Thank you. Good day, everyone, and thank you for joining us. My name is Peter Zonabend, and I'm the Chairman of Vivesto, representing Arwidsro, Vivesto's main owner and long-term supporter. It's a pleasure to speak with you about the journey this company has undertaken and the opportunities that lie ahead. Arwidsro has been a steadfast long-term owner, providing stability, capital and confidence that has allowed Vivesto to successfully navigate the period of major transformation. Shareholder support has enabled the company to rebuild and refocus, emerging today as a lean oncology-driven biotech with a clear strategic direction and strong operational discipline. Vivesto has evolved from a broad R&D organization into a targeted oncology company, one that applies advanced delivery technologies to address real medical needs, both in human and veterinary medicine. Thanks to that focused effort, Vivesto is now stronger, more agile and positioned for sustainable growth with a clear mission and structure built for results. Today, you'll hear more about Vivesto's dual track strategy in both human and veterinary oncology, which provides multiple paths to value creation. Vivesto is truly at an inflection point with a sharpened portfolio, strong ownership backing and significant potential to make a difference in cancer treatment for patients and companion animals. The Board of Directors fully supports the recently announced financing plans and the strategy that Erik and his team are pursuing. We are confident that this approach positions Vivesto for both scientific impact and shareholder value. So with that, I'd like to hand things over to Erik, who will walk us through the details of the strategy and introduce some of the experts joining us today. They'll speak about the tremendous unmet medical need that Vivesto is addressing through its innovative treatments. Erik, the floor is yours.

Thank you. Thank you so much, Peter, for those kind words. And thank you, Arwidsro and Per. Let me also heartly welcome you all here at Investor Studios, those who are joining us online and those who are listening in after the live broadcast. I will introduce the program for today and starting with the agenda, which is divided up into 6 different blocks, starting with the introduction, followed by our focus programs being Paccal Vet, Cantrixil and then followed by a brief update on the commercial potential of these programs as well. I will then summarize prior to us moving into a Q&A session. This slide depicts the speakers of today. You just heard Peter Zonabend, who is the Chairman of the Board and also the representative of our main owner, Arwidsro and the Board as well. We have also Henrik Rönnberg, who's a professor -- a veterinarian professor specialized in oncology, who will talk on the general medical need in veterinarian medicine and the opportunities that follow that as well. Jim Perry will talk on the specific medical needs that our program has the potential to serve, namely hemangiosarcoma and solid cancers in cat. And he's also the medical responsible person for our ongoing studies in the U.S. Today, we have also the honor of welcoming Bjørn Tore Gjertsen, who is an MD and a professor in hematology, who will specifically address the unmet medical needs within acute myeloid leukemia. Teresa Fernandez will talk on the programs and update you on the positive results that we've seen in both our programs, both Paccal Vet and Cantrixil. And Johanna Rostin, Chief Regulatory Officer, will address the next steps, the development plans, taking us to market approval for these programs. Nina Herne, who is a PhD and MBA will then describe the commercial potential of our focus programs. So this slide depicts the pipeline that we have within Vivesto. So it's the human medicine pipeline with Cantrixil, which is in the late-stage preclinical and Apealea, which has gone through a registrational study for ovarian cancer. And within veterinary medicine, we have Paccal Vet for dog, where we have an ongoing pilot study in hemangiosarcoma, which we recently presented very positive interim results for. And for Paccal Vet, we're also running a dose-finding study in cats. So our aim is to leverage value in the existing project portfolio. And for Paccal Vet, we have paclitaxel in a proprietary micellar formulation. And in addition to that, we had through previous clinical studies in dogs, quite extensive positive safety and efficacy data supporting the now initiated pilot study in hemangiosarcoma in dogs. Cantrixil is our new proprietary chemotherapy agent with -- we looked at various cancer opportunities and found that we had a combination of both unmet medical need and strong data supporting to continue within hematological cancer and hence decided to initiate preclinical studies aiming at a preclinical proof of concept within this area. For Apealea, the opportunity to unlock value within that program is to find partners, and we have a first licensing agreement with Zhida Pharma, who have not only the rights to the commercialization of -- for the Chinese market, but also production. So as said, we recently had positive data in our focus programs that is within Paccal Vet, where we saw strong data in the interim analysis that was newly recently performed. And with that, if we have similar data when concluding this study in the second quarter of next year, that will support a pivotal and registrational study and the way to the market. What's also very positive is that we've seen positive efficacy data, promising efficacy data in the cat dose-finding study in addition to good tolerability in the doses tested up to now. For Cantrixil, we've done a number of studies in the preclinical field. We've looked at difficult-to-treat human cell lines, both for acute myeloid leukemia, lymphoma and multiple myeloma and seeing very strong effects in these cell lines. And in addition, in an animal model, again, with a difficult-to-treat acute myeloid leukemia cell line, we saw effects not only in -- with monotherapy, but also in combining the drug with standard of care agents. What this has done is given us support to continue the development, not only for human use, but we also see opportunities within veterinary medicine, and we'll come back to that. So why the interest in veterinary oncology. You will hear more about that throughout this afternoon. There is strong underlying growth, which is explained by the increasing number of dogs and cats around the world and in addition, dogs and cats living for a longer period of time. In addition to that, pet owners are increasingly willing to pay for advanced therapy, therapy, which is similar to that offered to humans. Also, the market dynamics are attractive in that the time to market is fast, explained by less documentation needed by the regulatory agencies, supporting the unmet medical need within the pet veterinary medicine field. And there's strong support also from the regulatory agencies to bring new treatment opportunities to the market. In addition to that, there's limited competition, which means that once you have a drug on the market, there's a great opportunity to expand the use. So we have a planned rights issue, which is fully supported by guarantors and existing shareholders. This will give us a runway until mid-2027. And the proceeds will be used to finish the ongoing pilot study in dogs, which we expect -- where we expect to have top lines during the second quarter of 2026 and also during the first half of next year, the results from the ongoing dose-finding study in cats. In addition to that, we will run a PK tox study supporting both the human and the planned veterinary medicine opportunities running the first half of next year. And with the data from that, we will be able to initiate a pilot study in dogs, which should support not only the human next steps, but also a veterinarian medicine program. And this is planned to run during the second half of next year and the first half of 2027. In parallel with this, we intend to initiate partnering activities for both these programs, Paccal Vet and Cantrixil. And with the strong data that we have received already, we plan to initiate this early next year. And we believe that the data received so far will create partnering opportunities already at this stage. So why partnering then? Well, the simple explanation is that this will increase the speed and the effectiveness of development and also the commercialization of these drugs by adding capabilities necessary, both in terms of production and marketing, and it will also add necessary capital to finalize the late-stage development documentation and activities necessary. In addition to that, there will be the possibility to add complementary expertise and experience within late-stage production, clinical development, regulatory and commercial. So with that introduction, I'd like to hand over to Professor Henrik Rönnberg, who will talk about the need, the therapeutic alternative needs within veterinary medicine and the opportunities that comes together with that. So Henrik, please.

Thank you, Erik. Thank you, everybody, for coming here and being online. My name is Henrik Rönnberg. This is not my regular costume. I'm much more happy being in scrubs, as you can see there, performing clinical and clinical research in veterinary oncology. So I will share some views on veterinary oncology in general, and then we will have more specific information on the clinical trial currently ongoing in the U.S. So pets have become true family members emotionally and economically. We hear that from names like pet parenting for dog owners and cat owners and so on. So pet ownership drives well-being, mental health and lifestyle choices. We can feel that we are much better off when we have our dogs and cats together with us. And pet humanization fuels strong demand for advanced health care. So owners seek more good years, not just more years. So it's very important that the pets are feeling good when they are treated for different diseases. So the human animal bond has really evolved. Pets are family and society now expects veterinary medicine to deliver the same kind of quality of care we expect for ourselves. It's market driven by longevity and willingness to invest in the pets. So global companion animal health market is estimated to have USD 40 billion annual growth, which is a lot, and you can see references for that in the bottom of the slide. And owner spends more per pet each year. So it's really a growing market, and that's going to be on diagnostic, cancer care and also wellness. Interesting enough, there's international publications coming up as well on the willingness for owners to care more about their dogs. And 80% of owners say that they will pursue advanced treatment if available. That's also a thing that we need to develop more available treatments and the longevity trend and that rising lifetime health care spend per animal. So longevity, a success story with new health challenges, I would say. We have, over the years, got better food, vaccines and diagnostics, which in itself will create more longer lives. And then we see in our niche that age-related diseases really now dominates morbidity. Cancer is the leading cause of death in dogs over 10 years of age and mirrors human medicine a lot. So success leads to chronic disease management. As pets live longer, cancer becomes inevitable. It's an old man and old dog disease and old cat disease. So addressing it defines more modern veterinary care, I would say. Cancer in dogs then, scopes and relevance. Well, it's a high lifetime risk, 1 out of 3 dogs will develop cancer. And as I said in the earlier slide, over 10 years, it's the major cause of death in dogs. Frequent cancers that we see in the clinic is lymphoma, mammary tumors, osteosarcoma and hemangiosarcoma. We see that large breeds and pure breeds are over-representative to get these cancers. And it's also interesting to know that tumor biology closely parallels human oncology. Spontaneous cancer in dogs are not only a major welfare concern, I would say, that they are also true comparative models for human oncology, which I have done a lot of clinical research over the years and more and more interest in spending more finances on that, we'll see that. So how do you treat cancer today then? Well, surgery is still a cornerstone both for human and for veterinary cancer and that's specifically for local disease. We also have radiation, which works really well in a lot of indications. So it's effective, but unfortunately, limited access to that currently in veterinary medicine. And then we have chemotherapy, which is the main systemic approach for a lot of different tumors. We see more and more development into immunotherapy and target cancer treatments, but they're still in the early stage, I would say, and a lot in clinical research development and in the comparative space as well. So most dogs still rely on the classic cytotoxic chemotherapy that we are well aware of. So veterinary oncology has the same goals like human oncology, but unfortunately, far fewer dedicated tools available. There are a few drugs developed for dogs. So most that we see are off-label. So the majority of anticancer drugs that we use today, they are human generics, so-called off-label. Only a handful of veterinary-specific chemotherapeutics are approved globally. I would say that it's 5 to 7. Species-specific development increases scientifically -- scientific credibility and also safety information for us as clinicians. It enables individualized dosing, optimize efficacy toxicity balance and improved quality of life. So developing drugs specifically for dogs, I wouldn't say that that's a luxury. It's really essential for credibility, owners' trust and true precision medicine in veterinary oncology. So some people tell me that chemotherapy is really for the past, but it really remains foundational, I would say. So it's still the backbone of multimodal cancer therapy. Multimodal cancer therapy is a word meaning that you use different treatment options for treating the cancer. And sometimes you can then use lower dose intensity each treatment. You can go for less surgery, less radiation if you combine them, and you can also do less chemo if you combine the other 2. So multimodal cancer therapy is definitely what we try to use in the clinic. So the key role for chemo at adjuvant in surgery settings of postsurgical treatment, rescue or conditioning for immune therapy, which they the work on the immune system. So you have that to make the immune therapies work better. So many new modalities depend on the combination with chemotherapy. And we really need reliable, well-tolerated formulations, which remains a cornerstone of veterinary cancer care. So chemotherapy is definitely evolving just not disappearing. It's a platform up on next-generation treatments are really built. So the One Health Continuum then, naturally occurring cancer in dogs, they bridge human and veterinary medicine. Comparative oncology informs drug metabolism resistance and immune response and shared knowledge to really accelerate progress for both pets and people. So innovation in veterinary oncology exemplifies really the one medicine in practice. So every step forward for canine cancer care strengthen the one health link between animals and humans. And that's why I think it's really interesting that Vivesto has these shared tracks of human and animal oncology. I think that was it. So please.

Thank you, Henrik. After Henrik has been providing a more-broader perspective on veterinary oncology, I'm going to be focusing on our Paccal Vet program and the reasons why we believe this is a compelling market opportunity. As you may already know, paclitaxel is a well-established chemotherapeutic agent that has been used for decades in the treatment of human cancers. However, the formulations that are used for humans are unfortunately not available in veterinary medicine as cats and dogs are not able to tolerate it. And this is because the formulations are causing hypersensitivity reactions, but also they can lead to immunogenic reactions. So this has limited the use of paclitaxel in veterinary medicine. And this is exactly where Vivesto's technology is coming into play. We have already demonstrated that paclitaxel when it's administered in our XR-17 proprietary formulation, it's both safe and efficiently can be given to animals. So it is, therefore, we think we have a unique positioning for this program, and we are currently building up the value by having 2 studies that are ongoing in the U.S., one in dogs and one in cats, which I'm going to be focusing on in my next slides. So as I just mentioned, we are running a pilot study in dogs that have splenic hemangiosarcoma, which is an aggressive cancer that occurs commonly in dogs and the dogs are receiving surgery as the standard of care. And after that, for this particular trial, they are receiving as well 4 doses of Paccal Vet every 3 weeks. So the treatment phase is 12 weeks. And after that, the dogs are entering in a follow-up phase where they're being monitored with rechecks for tracking their health status, but also the treatment response. The trial is ongoing in the U.S. in 8 different veterinary clinics, which are spread across 4 different states. And currently, we have recruited 13 dogs out of the 18 that we have planned for completing the study. So we expect top line data in the second quarter of 2026 based on the current recruitment rate. And as Erik has already mentioned, a couple of weeks ago, we came out with some very exciting interim results from the ongoing study. The results are based on the first 11 dogs that entered, and we have compared these results to standard of care, which is the dogs treated only with surgery. And according to different publications, the overall survival of these dogs ranges around 60 to 86 days. However, in our ongoing study, we have seen that a median overall survival for the dogs receiving surgery and Paccal Vet increases to 138 days. That is what the black line is depicting in the graph here. And the 90% confidence interval ranges between 111 days and 163 days. That is shown by the dashed lines that are red and blue. And what that means is that the end results are with 90% confidence likely to be within this range. So that is very encouraging because even on the lower end, 111 days is already above this median overall survival for the surgery alone dogs. And you can also see in the graph that we have some dogs that have also been surviving for longer than 160 days. So in general, Paccal Vet seems to be doubling the survival of these dogs, which is extremely encouraging. Now moving to the Cat study. This is actually the first study being conducted in cats. And it was therefore important to test which dose the cats could tolerate. So this is a study that is being done in escalation until we can find the maximum tolerated dose. And we are recruiting cats that have different types of solid tumors, usually hard to treat or that have failed previous treatment modalities. And just like the dogs, these cats are also receiving 4 doses of Paccal Vet every 3 weeks. And the study is also being run in 3 sites in the U.S. and we have recruited 8 cats out of the 12 planned, and we expect top line data in the first half of 2026. As the study is ongoing, we only have preliminary results, but they are extremely promising. The first 2 groups that have completed the dosing have tolerated the treatment extremely well. We haven't seen any dose-limiting toxicities. So we are moving up to a third group that is currently ongoing at 80 milligram per square meter. So not only are the cats tolerating the treatment very well, but some clinical responses have also been observed in this study in different kinds of tumors, for example, in lymphoma and carcinoma. And Jim, who is joining us from the U.S., will be talking a little bit more in detail about both the cat and the dog studies and the medical need around that. So with that, I hand over to Jim. Thank you.

Hi, good afternoon. Thank you, Teresa, for that nice introduction and talk. I am -- my name is Jim Perry. Similar to Henrik, I'm a veterinary oncologist, and I practice based in the U.S. In addition to my clinical oncology duties as a veterinarian and probably the reason I'm here today is I'm also Co-Founder and CEO of CASTR Alliance, which is the contract research organization that is running these Paccal Vet trials, both the canine hemangio trial and the feline dose-finding study. So enough about CASTR. I want to move into the studies in general and why we're here. And Teresa, thank you again for going -- doing a brief overview of the results of the interim analysis of the hemangiosarcoma study and some of our early findings in the Cat study. But I think why I'm here and one of the goals of my part of the talk is just to really further explain the unmet need and the justification for what we're doing in these studies. And so I'll start with hemangiosarcoma. As many of you know, hemangiosarcoma is a tumor of blood vessels. It's very common in our veterinary population, and it's actually a similar disease what's seen in people. Also, it tends to be called angiosarcoma in people. but it's also aggressive in us and people as well, but it's extremely rare in people. So just setting the tone of not only is this a dog problem, but it's also a human problem as well. And just a perspective on how common it is, a recent study looking at -- it's the Golden Retriever lifetime study, where they're tracking Golden Retrievers specifically, they found 1 in 5 goldens have a lifetime risk of developing hemangiosarcoma. So very, very common. And to add to that, about 70% of cancer-related deaths in Golden Retrievers is from hemangiosarcoma. I don't want to just focus on goldens. I mean, very, as you'll see in our pet population of breeds in the study, which is in the lower right, we have a smattering of different breeds. German Shepherds is another very common breed. Portuguese Water Dogs and then obviously, mixed breeds are not immune to hemangiosarcoma either. So overall, it's very common, which proves that, yes, there is a market for this treatments for hemangiosarcoma. And one other point I wanted to make as far as this disease is that dogs of the disease aren't necessarily show any clinical signs until it's kind of at the life-threatening part. So dogs can kind of harbor this disease as it's growing in the spleen or potentially other organs. And when it becomes significant is when they actually grow to the point that the mass bleeds. So most of these dogs are presenting to emergency services or their primary vet on emergency with acute collapse secondary to bleeding. And just pulling our emergency service, our ER dogs here see about 3 to 4 cases per week of dogs with spontaneous rupture bleeding within their abdomen that could be hemangiosarcoma. And the reason I emphasize this is just these dogs are coming in, in essentially critical condition and their pet parents are faced with life or death decision. Do they send the dog to surgery to remove the spleen and stop the bleeding or do they elect humane euthanasia. And not to get too into the weeds here, but essentially, hemangiosarcoma is not the only disease that can cause rupture of the spleen or hemoabdomen, but what happens is when dogs come in, since hemangiosarcoma is relatively common and currently, the prognosis is relatively bleak, a lot of pet parents will decide to utilize their pet versus going to surgery under the assumption it might be hemangiosarcoma. And just another perspective is as a surgeon and oncologist, we probably see 1 to 2 of these cases going to surgery. I'd say to every other week, we see one of these cases going to surgery. So a lot of these pets are being euthanised. And statistically, about 30% to 40% of these pets being euthanised for rupture spleen may not even have hemangiosarcoma. So long story short, one of the goals of finding a treatment for hemangiosarcoma is not only to improve survival in dogs with hemangiosarcoma, but it might also decrease -- if there's a better prognosis with it, it might also decrease the number of dogs getting euthanised just with hemoabdomen. So kind of important from 2 points. And so I just added here kind of the average with surgery alone, the average survival is, as Teresa mentioned, about 1 to 2 months. And what we're seeing at least in the interim analysis in a relatively diverse population of dogs in the study so far, the survival time is about 4.6 months. So we are seeing a high likelihood that there is some single-agent positive effect to Paccal Vet against hemangiosarcoma. And that's important essentially or especially because if we have a veterinary approved if this gets through the approval process and we still see this benefit, this will provide not only an approved single-agent drug for this disease, but we can also potentially add it to other therapies that are not approved right now, but may have an additive effect against the treatment for this disease. So very, very exciting data, and hopefully, we can continue to see that trend. So that's the hemangiosarcoma study. Going back here, I just wanted to emphasize 2 of our pets as well that we've seen. So the German Shepherd in the upper right-hand corner is -- was our first patient and really set the stage for the trial. He was essentially the perfect patient every day coming into the trial. He'd walk in very noble and tolerated the treatment very well, got through all 4 treatments. The other dog in the Husky in this thing very similarly, tolerated -- did need some supportive care throughout, but got through all treatments and really helped shift this -- the curve in the right direction as far as showing improved survival. Now moving on to the cat study. So I will just right off the bat say we're especially excited to -- by the fact that Vivesto is interested in this treatment for cats as well just because right off the bat, cats are very much underserved, not only veterinary patients, but oncology patients. And it's not because they're necessarily underrepresented from a pet standpoint. I mean, looking statistically, there are more cats in U.S. households than dogs with over 75 million cats for the type of cats present in U.S. households alone. So there's definitely a market for therapies for these animals. And importantly, there are no FDA or USDA-approved cancer therapies in cats. Dogs, there's a few. So there's still not that many in our other species, but cats are especially underrepresented. And another big part of the cat picture is that the cancers that cats get do have a very similar -- I guess, a lot of the cancers that cats get are similar to the human side that are treated with paclitaxel. So the fact that they have a similar distribution of cancers as people with -- that get that treatment, having a treatment for cats that's paclitaxel-based is hopeful that we'll be able to treat these cats in general. And I've just put a graph here that shows kind of the more common cancers that we see in cats and how they are similar to what is on the human side that are treated with paclitaxel. So oral squamous cell carcinoma is probably one of the most common cancers we see in cats. It's the most common oral tumor of cats. It's also utilized as a model for the oral squamous cell carcinoma in people. Cats also get essentially the equivalent of triple-negative breast cancer, highly malignant cancer in cats that is also treated with paclitaxel in people. And then lastly, lymphoma, probably the most common malignant tumor we see in cats is commonly seen too. So the way we've designed the study in cats is that we're looking essentially at all measurable tumors. And since paclitaxel, really very few cats have been treated with paclitaxel based on how the traditional formulation is not tolerated well, no cats have received Paccal Vet. So one of the important parts of transitioning to this study is, one, find a dose that is safe for cats, make sure that they tolerate it. And then also in the recruiting of cats, we're doing all tumor types that are measurable, that will hopefully allow us to find a potential tumor type that might respond to paclitaxel or Paccal Vet. So the design of the study is essentially we're starting at a relatively lower dose just to make sure we don't overshoot tolerability. And we're enrolling 3 cats per group per dose. And as they receive the dose, we escalate the dose and continue to monitor responses. So, so far, we've enrolled 9 cats. 8 cats have received treatment so far with the ninth cat planned to receive treatment today. And really, I can't -- the data are pretty preliminary, but I'm very excited to see a lot of these response or cats we've seen so far have had at least stable disease as well as some partial responses, which is -- may not sound extremely exciting, but in the context of treating feline tumor specifically and also just any gross tumor, any response to chemotherapy to me is a positive. And while we may not be curing these tumors, one advantages of potentially using chemo in this setting is we might be able to use it in combination with surgery or other modalities to try to get that cure. So I just want to show an example. These are 2 cats that we've enrolled so far. The cat with the large neck mass in the first picture on the right, this is carcinoma cervical. This cat presented with a large mass next to his trachea, whether it being thyroid versus other type of carcinoma in the laryngeal region. This was very invasive based on palpation and had been resistant to other chemotherapies. Once we started the Paccal Vet trial, there was a noticeable shrinking. And also along with that, it became more movable. So there would be -- the hope was that we're going to be able to have a surgical option with this with more treatment with Paccal Vet. So we continued. It got to the point where we felt it was more surgical. We did a CT scan, but unfortunately, there's evidence of spread to the bone. So we weren't able to pursue surgery here, but it definitely provided an example of where neoadjuvant therapy with Paccal Vet might help us improve survival times. And then lastly, I'll end with the orange cat, St. Henry presented essentially in respiratory distress to our medicine department, was diagnosed with laryngeal and peritracheal lymphoma. The owners knowing that the lymphoma prognosis is so poor in general with standard chemotherapies, they wanted to try a new therapy. And Paccal Vet in the study put the cat into a strong partial remission to where essentially you could breathe normally and have a good quality of life again while on therapy. So the downside of the study is the -- or not downside, but just the way the study works. The study outlines 4 doses of paclitaxel. The carcinoma cat got through all 4. And as I mentioned on the next slide, the owners really wanted to continue paclitaxel, which just goes to show that people are wanting this therapy. The lymphoma cat unfortunately had to move away from our clinical sites. So it wasn't able to complete the full course of study. And unfortunately, that cat -- this disease progressed pretty quickly once it was off therapy. So the hope is here as we learn more about paclitaxel or Paccal Vet in cats, we'll be able to potentially dose it in a longer setting or make changes and really help more cats with these diseases as well. So I'll end with just kind of the preliminary data that both I and Teresa presented definitely shows promise for Paccal Vet in the setting of hemangiosarcoma in dogs as well as feline solid tumors in general, including carcinomas, lymphoma and potentially others. But importantly, too, I think the data speaks for itself, but also just what people are saying, and that's what really excites us as well. So not only the data, but just hearing what other oncologists have to say and also what the pet parents are saying. So I'll leave you with just the last discussion I had with one of our clinical sites, the PI there just really essentially said, thank you for bringing this trial to us and how much just the promise of new therapies and that we're working toward that is really helpful for their team and engagement and staying excited about the profession, especially when it can be pretty stressful seeing these pets progress and not have good treatment options. And then lastly, it's just the patient parents -- pet parents that enrolled in the study are just overall really happy with allowing their pets to be part of something that might not only help their pet, but also progress to helping other pets in the future. And again, as I mentioned with the cat, one of the clients was really, really hoping to get more. So I don't want to say addiction, but it is nice to see people wanting to continue with the therapy that they're receiving. And then just getting cats and other animals involved where everything else has failed is really nice and nice to give them an option. So with that, I just wanted to say thank you. If there's any questions, I'll be happy to entertain those. And next up, we'll have Johanna talk about how this drug will -- is being pushed through the manufacturing and study progress. Thank you.

My name is Johanna Rostin, and I will talk about the Paccal Vet program going forward. But first, let me start with a brief background to this project. The Paccal Vet program actually builds on a strong foundation of previous development work, a lot of documented data and a history of regulatory interactions. Starting with safety. We have, through previous clinical trials, gained a lot of knowledge about the tolerability and safety of Paccal Vet, and it's been shown to be tolerable to administer to dogs, and it does have unacceptable safety profile. It's been given to more than 300 dogs in previous studies and with the recent clinical trial in hemangiosarcoma, I think we are up to about 330 dogs. Efficacy next. So in the studies performed previously, we have seen that Paccal Vet has indicated antitumor activity in several different cancer forms, squamous cell carcinoma, mast cell and mammary tumors. and these are published data. When it comes to the manufacturing process, Paccal Vet is manufactured by the same manufacturing process as our human product, Apealea. So that means the process has been developed, validated and approved by EMA for human use. It's a well-defined process, which manufactures drug to a high quality. Regarding the regulatory interactions, there have been many regulatory interactions with authorities, FDA in the U.S. and EMA in Europe. Recently, we've had regular interactions with FDA, the Center of Veterinary Medicine on the hemangiosarcoma development program, and they've actually been very helpful and interested in this program. FDA also granted Paccal Vet, the so-called MUMS designation. MUMS stands for Minor Use or minor species. And this designation is the veterinary version of human orphan drug designation. It provides nice incentives to the sponsor companies and urges companies to take on development. The EMA has also granted limited market classification, which is the European version of the MUMS or minor use. So looking then into the Paccal Development Program for market approval. So right now, you've heard we are conducting a pilot study in hemangiosarcoma dogs and a dose-finding study in cats. And the top line data are -- we anticipate them to come in the second quarter of next year. In order to be able to continue this development, we need a partner. There are 2 major blocks of activities that will be performed before we can get full approval and place the product on the market. So when it comes to the manufacturing process, as I said, we have a reliable process in place. However, it needs to be set up at a commercial manufacturer, a company that is willing to take on long-term manufacturing of a veterinary oncology product. So it has to have the right capabilities, scale, regulatory knowledge. The second major block of activities relate to the pivotal clinical trial. So in this trial, and just to be clear, we will focus on the dog pathway going forward. It's a program that has come the furthest. So in this pivotal clinical trial, Paccal Vet will be compared with standard of care and statistically evaluated for safety and efficacy. So when can we anticipate to get market approval? This regulatory strategy, of course, needs to be aligned with the partner. But our current thinking is to file first with EMA for a conditional approval. This is enabled by the limited market classification, where a filing can be made based on very limited clinical data. So that application could be submitted after the CMC part of the commercial manufacturing process is in place. And this is, of course, very beneficial to place the product come early to market. When it comes to the U.S. FDA, we are now thinking to target the full approval pathway and await the clinical trial data from the pivotal trial. These different strategies relate to the different regional regulations and are -- have to do with the exclusivity periods that are obtained at market approval in combination with the commercial strategy. With this, we switch over to Cantrixil. So please let me introduce Bjørn Tore Gjertsen. He's a Professor in Hematology and will address the medical need in human AML.

Thanks for that kind introduction. Acute myeloid leukemia is the most aggressive blood cancer we have in adults. In contrast to children's leukemia, which is a lymphoid leukemia, acute myeloid leukemia is a more heterogeneous disease where the majority of patients are in the higher age groups. There is about 4 per 100,000 per year with new AML patients. But that's overall. If you go into the age groups above 70 years of age, it's 17 per 100,000 per year. So with an aging population, we are going to see an increasing number of patients. It is a heterogeneous disease. Of course, from a patient perspective, age, as we have mentioned, comorbidities, but what we are mostly focused on in this area in a way is the genetics of the disease. So there is mutations that are present more or less in all of the patients. And some of these recurrent mutations are very important for establishing and planning the therapy of the patients. What's new in the field and what's moving forward is now that it's more panels of mutations that are taken into consideration. And we also see outline of more protein-based biomarkers and other ways to molecularly characterize the disease. Patients that we consider fit and is in the age between 18 and 65, they have an expected survival, long-term survival, 5 or 7 years of about 55%. So that's not really -- yes, it has its limitations. Unfortunately, in the higher age groups, these therapies are not available or too toxic. And for unfit patients, we can get disease control, but still cure is very complicated and maybe not possible, for example, because of the lack of consolidation therapy in the form of allogeneic stem cell transplantation. We can easily divide the patient group into 3. And the third group is, in a way, the patients that relapse after therapy. The first one was mentioned as the fit patients. This is actually a therapy, intensive chemotherapy given in courses of about 4 weeks at a time, 3 to 5 or 7 courses. It can actually cure the patient. But we consider stem cell transplantation as a necessity to be able to offer a good standard of care in this patient group. And it's because of the transplant that we actually see 55% long-term survival in the group overall. In unfit patients, there is happening quite a lot of quite exciting developments. We can now establish control of the disease in a majority of the patients. And some of the patients, they have a median survival of more than 40 months. The problem is we are missing a consolidation therapy. If we are not able to bring them ship shape to a transplant situation, it's very difficult to cure these patients and a relapse will emerge. And for the relapsed AML, as you understand, that is the majority of these patients, there is no such as a standard of care treatment. The therapeutics mentioned here is an example of combination chemotherapy, the first one, FLAG-IDA venetoclax is an intensive regime, while the other one is somewhat intermediate where we get good disease control. However, in this landscape, all new therapeutics that are as good as or better than the options we already have is very, very welcome. We foresee that these patients need to be treated more in a kind of program. As I mentioned, the majority will relapse. We need a second option, and we need a second option that is tolerated nicely. On the left side, you see a stuffed bone marrow where most of the cells are malignant. There is some mature cells. And of course, these mature cells, for example, making platelets or red blood cells, as you can see indicated here, these cells need to be preserved if the therapy is going to be successful. We have some new formulations now, very exciting drugs, simple to give. They can be provided and administrated in an outpatient basis, but they still are hampered with adverse events. So we need new therapeutic options. If you foresee Cantrixil into our development plan for acute myeloid leukemia, it's quite natural that we start out testing the drug, the dose-finding parts in relapsed/refractory AML. And there is plenty of these patients, as mentioned. It's not very difficult to recruit patients to clinical trial. These clinical trials, they will need to explore combinations, sequences that are beneficial. In all new drug development programs, it's very important to think about biomarker strategies and searching for subsets that are more sensitive than others. The current landscape of conventional chemotherapeutics is -- it is a fact that we know that some patients will have -- really have benefit from the drugs, but we cannot foresee which of the patients will be the beneficial responders to retreatment. So combinations and genetic subset, for example, as [indiscernible] is very important to bring with us also from the first patients that we treat. Then if we have a clear biomarker strategy, it's quite obvious that the first-line treatment that is given today is also in a kind of shift. There is interest for less intensive therapy, which can bring the patient to the consolidation therapy currently as all hematopoietic stem cell transplantation. So with those words, I will hand over the word to Teresa.

Thank you so much, Bjørn Tore. So I'll be focusing now on our Cantrixil program, which is a new class of chemotherapy that we are developing for hard-to-treat hematological cancers. So Cantrixil is a potent and selective third-generation benzopyran that has a unique mode of action and we've previously shown that it can actually target the full spectrum of cancer cells, including those more resistant tumor-initiating cancer cells that are thought to drive cancer relapse in patients. As you already know, we are currently in preclinical development. And we have previously also shared throughout this year and the previous year, some positive results within the program. However, we haven't really been able to share many details on these results because we were working on filing a patent, and it is, therefore, very important to keep those results confidential. We have now filed that method of use patent which means that I'm happy to be able to share the results that form the basis of that patent with you today. We still have some preclinical work ahead of us. So we are expecting to enter in clinical development sometime after 2026. So I would like to guide you through the first set of experiments and results we obtained within the hematological cancer [ sphere ]. And here, we began by testing Cantrixil in a panel of different cell lines derived from patients with diverse hematological malignancies. We selected these cell lines based on different mutations and disease backgrounds to sort of have a good starting point to understand whether Cantrixil could be effective in all of them or maybe just in a subset. What you can see in the graph is that Cantrixil was effective and has strong effects throughout all of these cell lines and what the bar is representing is that the shorter they are, the strongest effect of Cantrixil was. So it was very, very interesting for us to see that we obtained the strongest results in the cell lines that were coming from patients with relapse. So it was because of that with these results and also the high unmet medical need and the strategic business potential that we decided to move on to AML as an indication. And as Bjørn Tore has already explained, AML is often treated with multiple drugs. So we wanted to set Cantrixil in the context and understand whether it could enhance the effect of standard of care agents already used today. And here, you have 3 graphs where Cantrixil was tested alone, but also in combination with venetoclax in blue. We have azacitidine in green and cytarabine in orange. And in the same way here, the shorter the bars, the strongest effect and the bars that are striped are the ones showing the effect of Cantrixil in combination, with this standard of care agents. So what the graphs are telling us is that Cantrixil actually had synergistic effects with all of these different agents, which is interesting and important moving forward in the development. These results were obtained in vitro. And obviously, it was also important to understand whether these effects are also consistent when we move into animals. So we performed some experiments using a mouse model of AML. Basically, these mice are injected with cell lines derived from AML patient that are then left to spread around the body to cause tumors And the tumor growth can be followed, and we can also follow the overall survival of this mice. So what you can see on the graph on the left is the effect of Cantrixil in the tumor growth as compared to a control group that was treated with cell line. So we had 3 different groups where Cantrixil was dosed at different levels. And in all of the 3 groups, we saw that the tumor growth was statistically significant. So it was lower than in the control group. And what we also saw is in a different set of experiments. We compare the standard of care with venetoclax and azacitidine to a group having also country. So basically a triple combination group. And it was interesting to see that, firstly, this animal tolerated triple combination treatment extremely well, which is important because we don't want to be adding any extra toxicity to this group, but also we saw a significant improvement in the overall survival of the mice when Cantrixil was added together with the standard of care. And although in the curve, it doesn't look as a very big difference on the days. I want to highlight that this is a very aggressive model and small differences in the days is expected, but there were still significant -- statistically significant and of importance is that the survival curves are not really overlapping. So that adds also a level of significance to these results. And the results I have presented to you today are comprising the patent application that has now been filed and hopefully can extend the IP for Cantrixil until 2044. So with that, I leave the floor to Johanna.

Okay. So I will talk about a potential development program for Cantrixil in human AML. So Vivesto is now preparing to perform an exploratory PK tox study in dogs. We will investigate the pharmacokinetic properties and toxicity in dogs, a larger animal model at this time. And this would be performed during the first half of next year. In order then to continue the development program, we need a partner. Since Cantrixil is now entering in clinical phase with a new indication, we would start with the Phase I study and then progress to the conventional Phase II and III. We also need a partner to support in the CMC development. There remains to be done and to optimize that process. With that said, I would like to switch over to talk about Cantrixil for veterinary use. We think this is a really interesting opportunity given Cantrixil's unique mechanism of action and promising safety profile. It may be very beneficial and a good option for treating animals. First, to explain a little bit more about the synergies that we see between Cantrixil human and veterinary medicine development and to do those pathways in parallel. With the synergistic development pathway, we mean that the study data from any in vivo study can be useful in adding information both to the human development as well as to the veterinary programs. For example, the upcoming PK dog study in dogs will support rationale and justifications for giving -- for guiding on the dosing in both animals and humans. A lot of research has been done on Cantrixil already, and we now have knowledge about the biological effects across species. So we have gained positive results in multiple species and different -- several different cancer indications. We see that costs and time lines can be shared and thereby reduced in preclinical work as well as on the development of manufacturing process. So the Cantrixil development program in dogs then would look like this. Once more, I already described the PK tox study that we are planning for to be conducted first half of next year. We're also planning to initiate a pilot study in cancer sick dogs, and that will provide a very important milestone. It will be -- give information on the safety and efficacy in cancer sick dogs, and that will guide us also on -- to predict on the human side, if it has potential. In order to continue the development program, we need a partner. We need to do a regulatory required safe study, the clinical pivotal trial and also CMC development, which could be a joint effort then with the human development work. And I will stop there, and I will give the word to Nina Herne and talk about the commercial potential.

Thank you, Johanna. We will talk -- I will talk about the 2 programs that Vivesto has and some data around and information around the markets that they are targeting. But first, I would like to start with why Vivesto and its owner considered the global veterinary industry to be a very interesting industry. Well, the global veterinary industry is fast growing, and there are mainly 2 reasons for this. One has to do with the pet owner's mindset and the other has to do with the industry as a whole. As Henrik Rönnberg talked about before, and I'm just summarizing and repeating what he said here is that there is a change in the mindset of the pet owners such as they view their pets in a different way. They consider them more to be family members than to be pure animals. And with this, there is a willingness to pay not just for treatments, but for other benefits as well for these new family members. This means that they want their animals to live as long as possible. So with good nutrition and good treatments, there is an aging pet population. And with this, they will also suffer and be exposed to new type of diseases, including cancers. This means that there is a growing need for treatments that are not just investigated but also developed for pets. On the industry side, there is a change in the landscape. There is a growing interest from the big pharma companies to move into animal health. And they do this in a focused manner, by having focused animal health companies to be specialized on new treatments for pets. With this, there is also an unprecedented right in an ecosystem around the animal health industry, which is -- has a clear focus on pharmaceuticals and biotechs. So there is new inventions and new treatments coming into this industry. This means that the global companion animal health market has more or less doubled in the last 10 years. And if you're looking on the top 10 companies within the animal health companies, they are growing faster today than the top 10 pharma companies. The estimated value in 2023 of the top 10 global animal health companies was up to USD 143 billion. We're now move into the Paccal Vet program with the clear folks within dog cancer, but also cat, but I will only speak about the drug cancer today. There is a growing number of pets, especially within -- on the dog side. The market -- estimated market size in 2025 was nearly 94 million registered dogs in U.S., close to 100 million in Europe and in the rest of world, almost 300 million. The prevalence of the disease target or the targeted disease that we have or indication within Paccal Vet program, which is hemangiosarcoma, is 53 dogs out of 100,000. We believe that the Tanovea, which is a recently approved drug for lymphoma is a good benchmark for pricing -- setting the pricing for Paccal Vet within hemangiosarcoma both in U.S. and Europe, and the estimated pricing then will land between USD 3,000 to USD 3,500 for a full treatment. So this is -- there is a good market for Paccal Vet within hemangiosarcoma, but there is also a good opportunity outside hemangiosarcoma because as we talked about before, there's 1 in 3 dogs that will develop tumors and 1 in 2 dogs will actually over 10 years, will suffer from cancer. So the incident in dogs are close to 400 dogs per 100,000 dogs will suffer from cancer at some stage in life. So there is a large opportunity here to expand into other tumors outside hemangiosarcoma, such as the squamous cell carcinoma, where we already have data, but also mast cell and mammary tumors. Moving into the Cantrixil in AML. A few words here on the market within the AML. The market size here in the 8 major markets, and now we're counting U.S., Europe, Japan and China as well. Their estimated number of patients within 2032 will be close to 96,000 patients. The market value of that will be close to USD 3.7 billion. And as Bjørn Tore talked about, even if there are treatments today, standard of care treatments, there is still a large unmet medical need within this patient population group. The incidence is around 4.3 patients per 100,000. And the prognosis is very poor, 5-year relative survival is close to 33%. Bjørn Tore talked about a little bit where there is the greatest need within AML, and there is a large need within the relapsing in refractory patients where there is no standard of care and where Cantrixil could be a drug to meet that unmet medical need. To give you a sense of possible pricing of Cantrixil within AML, we look towards venetoclax, which was recently approved for AML patients. And here, we're looking towards an annual pricing around USD 80,000 in U.S., in Europe, half of that and in Japan, roughly the same as in Europe. And now moving over to summary to Erik, back to you.

Thank you so much, Nina, and thank you all the speakers for today. I think it's been a really exciting afternoon. Thank you to everyone in the room listening still and also on line. I think we've had not only an exciting afternoon, but an exciting year as well. We've had really positive results that will help us in the upcoming year as well. Those positive results really paved the way to the next steps in the program and also the expansion of the programs in terms of the cat study when it comes to Paccal Vet and the Cantrixil Vet study as well. . So with the planned rights issue, we will have investments that will take us through very important milestones also next year, those being the completion of the dog pilot study, the second quarter next year and the cat study sometime the first half of next year, enabling not only initiating pivotal registrational study, but a conditional approval along the way in Europe. We will also have a PK and tox study in Cantrixil during the first half of next year, supporting both human -- continued human and veterinarian medicine, clinical development and a pilot study with Cantrixil in dogs starting towards the second half of next year and continuing the first half of the year after that. In parallel, we will initiate partnering activities starting early next year on the back of the positive results that we've seen so far. So with that, the presentations are concluded and I asked the Vivesto team to come up. We will also have the experts available. So if you haven't already mailed your questions, please do so now. And yes, we'll be ready to take any questions you have.

#13

Well, thank you very much. It was a Lam presentation, but I think it was very giving for investors. And I think we should begin with the Q&A. We have a lot of questions from the viewers, but I'll begin with a general question about the company. Considering that we have talked about a lot of drugs in development currently Paccal Vet and, of course, Cantrixil. I'm also curious Apealea because it seems like you're stepping into one part of business into another when you're starting these developments. What sort of key highlights do you take with you from the time with Apealea into the time now that you're developing new drugs?

Erik Kinnmann

executive
#14

I think that's what we were alluding to somewhat and what also Peter gave us a background is that we are a much more focused company now. The company had previously the ambition to do both early discovery, preclinical work, development, production and commercialization. I think what we've learned throughout those years is that given also the development of the capital markets, it's better to be focused. So hence, the focus on the current programs and relying upon partners, not only for those programs at a later stage, but also leveraging the value in Apealea.

Mikael Magnusson

attendee
#15

And what are your expectations ahead? Can we expect in the super long term, perhaps that you will add more programs?

Erik Kinnmann

executive
#16

I think so. Still focusing on late-stage preclinical and early clinical. That's certainly possible. And as we heard today, veterinary medicine is a great opportunity, and there's a great medical need as well. So it's not unlikely that we will look at programs in that field.

Mikael Magnusson

attendee
#17

We'll move on to your liquidity and capital raise. You're raising capital SEK 53.8 million. And considering your current portfolio of projects, I know that you spoke about this in the presentation, Erik, but what will you be able to achieve with this capital raise?

Erik Kinnmann

executive
#18

The capital raise will take us through the important milestones that we outlined. I think on the back of the very positive results that we've seen, we will also be able to initiate partnering activities. They will be curious to see and excited to see the data that we've shown so far. And with the capital raise, we will be able to complete the ongoing activities, which I think will enable us to actually strike deals also with partners that will be able to add the resources necessary to the programs.

Mikael Magnusson

attendee
#19

If you were asked how much capital will be added to the bank after the rights issue is completed, do you see any income within the next 2 years? Or shall we calculate another rights issue in 2027?

Erik Kinnmann

executive
#20

I think that's a very valid question. We have in our budget for enabling these various activities is not anticipated partnerships -- partnership deals being struck. But on the other hand, if they do, we will expect significant upfronts, which will help us to continue as we said, now the runway is some to the mid of 2027, that would certainly extend that as well. And what I'd like to be clear about is the continuation of the programs, as we've said, also requires partners who we expect to actually provide not only resources in terms of capabilities and expertise, but also financial resources.

Mikael Magnusson

attendee
#21

And Peter here with [indiscernible], you're supporting this capital raise, of course, during your [ pro rata ] we say, which other significant shareholders are committing to this issue?

Peter Zonabend

executive
#22

Well, I think we are the largest one by far. So we have seen interest from the other ones on the top 10 shareholder list. But given our size, it's obviously most important that we not only take our pro rata share, but we have also committed to SEK 50 million in the underwriting.

Mikael Magnusson

attendee
#23

And your support doesn't -- isn't really limited to just being shareholder. There's also a credit facility that investor has SEK 10 million, which has been utilized so far. What is the terms of the credit facility?

Peter Zonabend

executive
#24

Well, the credit facility that was put in place earlier this year was SEK 10 million at 8% interest rate and...

Erik Kinnmann

executive
#25

It's the same terms.

Peter Zonabend

executive
#26

It's the same terms, yes.

Erik Kinnmann

executive
#27

8%.

Mikael Magnusson

attendee
#28

All right. And tell me, Erik, is it reassuring to have the largest shareholder being this sort of pillar of support?

Erik Kinnmann

executive
#29

Of course. Obviously, always been there for the long haul, and we're really, really grateful for them continuing to supporting us. And I think that sends a strong signal. Peter and I have very frequent contacts, and I think that should send a strong signal also to other investors that we're on the right track and new strategy and the focused portfolio and especially since we've received these very positive results now recently as well.

Mikael Magnusson

attendee
#30

And of course, there's also milestone payments in the pipeline as far as I understand, linked to Apealea and the deal with China in [ Zhida ] $5.85 million in milestones plus royalty. How much of that package do you consider to be achievable? And what sort of time horizon?

Erik Kinnmann

executive
#31

I think all of it is achievable. I mean, we have already performed the pivotal trial, and that led to a market approval in Europe. We don't think that the regulatory agencies will look very differently upon those data that's been achieved previously. Obviously, there is some activities that needs to be done. Some complementary studies will be needed in China as well as setting up new production since [ Zhida ] Pharma will actually produce the drug, at least for the Chinese market as well. So there there's a couple of years needed before we get any significant milestones and royalties, I would say.

Mikael Magnusson

attendee
#32

If you asked if there's any signal from the Chinese party, they want to move forward to sell Apealea on the market? And when can that happen?

Erik Kinnmann

executive
#33

We have some interest from various territories in the world, nothing concrete at this stage. So this is not our focus. We do think that there's some value there, but it necessitates new partners as well. Obviously, if the Chinese companies are successful, they would be able to produce this provided that they get the approval in other territories as well. And with production in place and approval in China, it would be more attractive to expand into other territories as well.

Mikael Magnusson

attendee
#34

Yes. Exactly. And that leads me to the question from the viewer. Are any partners being sought for -- any other markets here, example, Latin America and European?

Erik Kinnmann

executive
#35

To be honest, I think Europe may be challenging. We've been there already. But both Middle East and Latin America and African countries would probably be of more interest. These are areas where some of the major other pharma companies are not as active and there are other players who actually successfully can find margins and success in those territories.

Mikael Magnusson

attendee
#36

I'll continue to ask questions openly and anyone can just jump in because now we'll move on to Paccal Vet. And I'm curious, considering the sort of niche towards pets and animal dogs and cats. How does the regulatory process differ from working with drugs for humans?

Johanna Rostin

executive
#37

Well, in general, the requirements are not lower, but less extensive proof of burden on the sponsor companies, I would say. So where we would have multiple studies with hundreds of patients in human cancer type. It doesn't really have to be that many patients on the veterinary side and the studies can be much shorter. So -- and I mean it's from a safety, it's from an efficacy, it's ethical standpoint as well, maybe not as high requirements on the veterinary side as on the human side.

Mikael Magnusson

attendee
#38

And what does that mean in terms of time lines?

Johanna Rostin

executive
#39

Well, it does mean that the time lines can be significantly shorter than compared to human program. It's difficult to say exactly how, but in general, the regulatory required studies are not so many on the pet side.

Mikael Magnusson

attendee
#40

And assuming that the final pilot data in dogs remain in line with the interim readout. What are the next concrete regulatory steps to sort of determine whether or not you will move into a pivotal registration-enabling trial?

Johanna Rostin

executive
#41

I would say that the first thing we would do is to share the clinical study report with the FDA and submit that to our open IND that we have and then go for -- start preparing for a quite extensive scientific advice meeting both with the EMA and FDA. It's very important to align the strategies and activities with the regulatory expectations. So...

Mikael Magnusson

attendee
#42

So what will be the minimal viable design that still satisfies regulatory and future commercial partner.

Johanna Rostin

executive
#43

What do you mean...

Mikael Magnusson

attendee
#44

What is the minimum viable design that still satisfy the regulators and the future commercial partner?

Erik Kinnmann

executive
#45

I think it will somewhat depend upon the final results we get from the study. But if we see similar effects as outlined by Teresa earlier, it's a quite limited study. The regulatory agencies will require safety data, given what Johanna also outlined in terms of we have already since before, 314 dogs, and we're adding to that. I think the efficacy will be what actually steers the number of dogs required in the pivotal study. So we're expecting at least 100 dogs, but somewhere between 100 and 150 dogs.

Mikael Magnusson

attendee
#46

And remind me, when do you expect this to be on the market?

Johanna Rostin

executive
#47

On the market, I think it depends on the partner. Of course, we hope for a strong partner that can support us very efficiently. But I would say 3 years or 4 years, something like that.

Erik Kinnmann

executive
#48

Three years. And we might add to that also that in terms of initiating such a study, obviously, there needs to be a regulatory agency interaction, and we planned an international study, and I think a partner will agree. But to start that, we need a clinical trial material also, and there is existing clinical trial materials. So it's not a bottleneck. Johanna outlined the need to start commercial production. That will be sort of the limiting factor in terms of getting approval and reaching the market as well. So the sooner we can get a partner, the better.

Mikael Magnusson

attendee
#49

It sounded also in the presentation that you need a partner. Can you elaborate a little bit on why having a partner is so important in this and why you can't do it on your own?

Erik Kinnmann

executive
#50

I mean the obvious reason is the capabilities in terms of production and the marketing organization as well as financing the program. I think ideally, we would find a partner amongst the 10 largest veterinary medicine companies. But if it would be such a company or a company that would like to focus on one territory, then I think that based upon that and validated by that, we could seek additional funding. But that's not the first option. It's sort of a second option as well. But I think that finding a partner is both finding the resources, but also finding the validation of the program. You've heard quite a lot of support for both the medical need and the commercial potential of these programs as well. But I think an additional such validation will be through a partner as well. That's an additional factor for why it's important.

Mikael Magnusson

attendee
#51

And without telling us too much, have you already initiated discussions with potential partners?

Erik Kinnmann

executive
#52

We've had a couple of very few preliminary discussions, but that has been more sort of circumstantial. I think that, as I indicated, we will start a process more in the beginning of next year. What I can tell you is that we are looking into the possibility of working with business development consultants to make this as effective and professional as possible. And this is something that we have put in the budget for next year and the first part of the year following that as well.

Mikael Magnusson

attendee
#53

And it's also a matter of finding the right partners. There is a view...

Erik Kinnmann

executive
#54

Exactly.

Mikael Magnusson

attendee
#55

Express a little bit of concern that one might find a partner, but the partner might not take the product to market. What -- how do you ensure that, that won't happen?

Erik Kinnmann

executive
#56

Well, one reason for choosing a very professional business development partner is to actually get the boxes checked in terms of the resources and the capabilities to actually take a program and take it successfully, not only through development, but also in production and also commercialization of the programs.

Mikael Magnusson

attendee

The same viewer also expressed as a little bit concerned about the market that Paccal Vet that will meet in terms of, for instance, dog insurance et cetera and the sort of payment power of the pet owners/customer. Can you elaborate a little bit on the sort of market you will enter into the U.S.A. with Paccal Vet?

Erik Kinnmann

#58

And I think, as we heard throughout the afternoon, this is certainly an increasing market, not only in terms of numbers, but also in terms of willingness to pay. And we're seeing that through not only the few products that are actually approved for veterinary oncology and -- but the prices paid. And what we've become more and more aware of is that there are actually activities ongoing in terms of developing drugs specifically for the veterinary market, even drugs that will have really high prices because these are biologics and more expensive to produce as well. So there's -- it's not only us that believe that this is a growing a very interesting market, but there are also some competition even if it's not the same as in pharma.

We're also going to talk about Cantrixil. But before we do that, I will turn to the crowd and see if there's any questions here. No. All right. Then we'll move on to Cantrixil, giving the synergistic effect seen with standard of care drugs. Do you envision the first AML trial as monotherapy dose escalation study followed by combination? Or would you move directly into combination trial?

Erik Kinnmann

executive
#60

I think that the first trial needs to be a monotherapy, but you start then with the combination therapy and work towards a monotherapy once on the market. And I would turn to Bjørn if you have any comment on what a development program for Cantrixil will look like.

Bjørn Tore Gjertsen

attendee
#61

Yes. As the development of these drugs in such a complex disease can have different solutions in a way. One model can be to launch a Phase I trial, which is signed with the idea that it can be adapted. So first, we determine the dosing, looking for signals of therapeutic effect and then eventually build it up with one or a few combinations in small arms. One of the design that I fancy myself just now is a small design that we use in academic trials where we try to repurpose label drugs, 8th patient, for example. And if we strictly defined clinical benefit, then you can say that if there is one or more clinical benefits, then we can scale it up plus 16 patients. And in that way, you have a go/no-go level at all stages. I think that's very important. If there is unforeseen toxicity or problems or a group of patients that do not should have this treatment, it's important to identify them early on. What's may be more interesting is the fact that in these early trials, you can get signals on who are actually really responders. And of course, we are searching for exceptional responders the whole time. That's what we hope that you have in your portfolio.

And assuming that you reached full funding, what are the next steps and time frames to get Cantrixil to first clinical study?

Erik Kinnmann

executive
#63

Thank you, Johanna -- Could you take that question?

Johanna Rostin

Mikael Magnusson

#65

Assuming that you have reached your funding, what are the next steps to get the Cantrixil to first clinical study?

Johanna Rostin

executive
#66

So as I said, we will run now a PK tox study. We will do a pilot study in the dogs. Then we need to -- I mean, we have for Cantrixil a lot of data in various models, animal models, and we also have in humans. Still, we might need to do a gap analysis on the GLP tox to do some complementary work there. And we need to have CMC development coming a bit further then we could start in Cantrixil Phase I.

Mikael Magnusson

attendee
#67

And what is your strategy regarding partnerships to Cantrixil? And how does it differ from Paccal Vet?

Erik Kinnmann

executive
#68

Well, for Cantrixil, we wish to get a partner also at this stage to actually enable the activities that Johanna outlined. I think the expectation in terms of Cantrixil is perhaps a more specialized pharma company, and it could be a global player. It could also be a regional player. But we are quite open in terms of the structure of such a deal, but we certainly do want a partner before taking the next steps. We will do is the preparatory activities in terms of the PK tox that's covered by the planned rights issue, and also the pilot study.

Mikael Magnusson

attendee
#69

And as Johanna sort of mentioned in the beginning of this Q&A, the regulatory times and the process, it differs a lot. What about when looking for partnerships comparing the veterinary line towards the human line?

Erik Kinnmann

executive
#70

Yes, that's going to be quite different. I myself have a background with human medicine as well. So I know business development quite well and how to optimize that in terms of human medicine. I'm not as familiar about veterinary medicine and partnerships in that field. And obviously, there are some similarities in terms of companies having a veterinary medicine arm as well as human medicine. There are separate veterinary medicine companies that are amongst the largest as well. But all in all, this is a good reason for why we want to find and identify a business development consultant who actually is knowledgeable, especially about the veterinary medicine field, but also human medicine and a potential partner for Cantrixil as well.

Mikael Magnusson

attendee
#71

We will soon turn to Jim Perry, who is joining us via link. But before we do that, we will turn to the audience again if there are any questions.

Unknown Analyst

analyst
#72

Yes. Just a reminder about the toxicity profile of Cantrixil. And how it -- if it's overlapped with the drugs like venetoclax and azacitidine perhaps.

Teresa Zafra

executive
#73

So at the moment, in the preliminary results that we have seen, we have actually not seen any toxicity. Usually, when you do studies in mice, you would like to see that they don't lose more than 10% of weight. And we have been within that level. So that's the reason why now we would like to do this PK tox in dogs to see that these results are replicating. I know that venetoclax and especially azacitidine are quite toxic. So if we would be able to add Cantrixil, that maybe would allow us to have a lower dosing on these venetoclax and azacitidine as well to have a more powerful effective treatment. So that's the reason why it's so important to see synergy in these results, but also that there is no overlapping toxicity. But we need to look a little bit more in depth now. And that's why we want to turn to the dog studies, which is auspicious that resembles humans much more than mice.

Unknown Analyst

#74

And also out of curiosity, why do you think you see better results in the cell lines with resistant tumors?

Teresa Zafra

executive
#75

It's very interesting. I know that we have already data from other cancer types, and we have seen the same. Perhaps it is -- has to do with the mechanism of action of Cantrixil. So I mean, it's very encouraging, and I hope that we can dig into that much further. But at the moment, yes, we were happy to see these results and also interested. Yes.

Erik Kinnmann

executive
#76

What has been observed previously is that there is an effect on stem cells, maybe that could be one of the factors actually explaining that finding.

Mikael Magnusson

attendee
#77

Thank you as well. Are there any other questions from the audience? No. All right. So then we turn to Jim Perry, who gave us a slide here in the presentation. Jim, from your perspective, as study operator, what will the pilot study need to show justify moving into a larger registration-enabling trial. Jim? From your perspective as a study operator, what will the pilot study need to show to justify moving into a larger registration-enabling trial?

James Perry

attendee
#78

I think from my perspective, again, as medical monitor and running the studies in the U.S., I think just seeing a continued promising benefit of efficacy in the pilot study would gear that next step to justifying a pivotal trial and also continuing to see the tolerable dose that we can use to kind of match the potential efficacy.

Mikael Magnusson

attendee
#79

There is more owners today willing to pursue advanced care for their pets. How strong is the demand today for more advanced -- more effective veterinary oncology treatments?

James Perry

attendee
#80

I mean my perspective is mostly just on the clinician side. So I just see the pets that come to me. So speaking for sheer numbers is a little difficult from my perspective. But just for my clinical practice, we see -- our schedules are filled up with patient clients that are willing to pursue treatments for their pets. So at least from an on-the-ground perspective, there's no -- kind of no limitation on the number of pets that we see. Relative to the available veterinary specialists to treat these pets, we see plenty of willingness to move forward with advanced treatments and costly treatments to be honest.

Mikael Magnusson

attendee
#81

Henrik showed a slide that 80% is willing to pursue these advanced carry, if I'm not mistaken. But what about the other 20%? Why did they not to move on to advanced care?

James Perry

attendee
#82

I'm sorry, can you repeat that again?

Mikael Magnusson

attendee
#83

From Henrik's slide, I saw a statistic that was 80% of owners want to pursue advanced care, but I'm curious more about the 20%, why they do not wish to pursue more advanced care?

James Perry

attendee
#84

Yes. I mean I think -- and Henrik, I don't know if you want to add to that. I mean, I can give my perspective. A lot of it comes in, not necessarily cost, but also after the discussion of giving the estimated prognosis with a certain treatment as well as cost. And another big component is just ability to come to the clinic and spend time based on the pet parent schedule. Is that something that they can do feasibly, not just financially, but from a time standpoint. So I think that's my best estimate of why we do have a fair number of people not able to pursue treatment or they like to pursue other nontraditional therapies based on what their feelings are.

Mikael Magnusson

attendee
#85

What can you tell us about how it's treated today?

James Perry

attendee
#86

Yes. So I mean that's a good point. We didn't go in too in depth about and specifically hemangiosarcoma, but it's kind of 2 points of standard of care throughout these studies, we're comparing a lot to surgery alone, but a step above which most treatments of their clients that are pursuing chemotherapy for hemangiosarcoma were using doxorubicin as a single agent, and that's off-label. So not approved for veterinary medicine, but it's obviously generic and a long-running chemotherapy. So standard chemotherapy for hemangiosarcoma right now is doxorubicin and also has single-agent efficacy shown throughout many trials or not necessarily trials, but just experience. Importantly, with doxorubicin, while it is tolerated fairly well in most animal patients, it does have a unique toxicity that makes it not necessarily available for all pets. It has very specific cardiotoxicity. It also has limited number of doses you can give based on that toxicity. So not only having another efficacious drug out there for the hemangiosarcoma, it might be able to be used -- Paccal Vet could be used instead of doxorubicin in those patients or there's potential once we get more information on the use of Paccal Vet hemangiosarcoma, there might be an option to combine it with doxorubicin or other modalities that are yet to be out there. So I think it's not a direct competition with doxorubicin or other drugs we use now, but it's potentially complementary and just having more option out there is useful in my perspective from a clinician.

Mikael Magnusson

attendee
#87

Another statistics that I noticed in the presentation. I don't recall if it was yours or Henrik, but 1 in 3 dogs get cancer. And if we compare that to other domestic animals and even humans, how does that statistic short of sort of compare?

James Perry

attendee
#88

Yes. I mean I can't comment too much. I mean, from other veterinary species cats as well that develop a lot of cancers. I think it just more represents the -- that's a lot of numbers out there. So I don't know if I have a specific answer to shift, but there's definitely the need there.

Erik Kinnmann

executive
#89

Can I just -- my response to that from a human perspective would be that working better and better to actually prevent and treat cardiovascular disease for humans. So it's becoming less common. And because of that cancer is becoming more and more common in humans as well. And it's a disease of the elderly as well. So -- and probably if you look a number of years ahead, it will be the most common reason for dying as humans as well and perhaps neurodegenerative diseases as well. But it could be that we're getting more healthy in a way, similar to our pets.

Mikael Magnusson

#90

And as I now head into the final question, I will turn to the crowd once more and see if there's any questions here. All right. Then moving on towards the new year-end 2026, 2027, can you share with us some highlights that investors should look forward to?

Erik Kinnmann

executive
#91

Of course, those following Vivesto have a lot to look forward to. We've had a very exciting 2025 and look forward to an even more exciting 2026. And delivering these programs, both in terms of the cat and the dog study for Paccal Vet and the continued Cantrixil studies. And what we also have ahead of us, I think, is news as we move along 2026 in terms of partnering as well.
