Viking Therapeutics, Inc. ($VKTX)
Earnings Call Transcript · April 29, 2026
Highlights from the call
In the first quarter of 2026, Viking Therapeutics (VKTX) reported a significant increase in research and development expenses, leading to a net loss of $158.3 million or $1.37 per share, compared to a net loss of $45.6 million or $0.41 per share in the same quarter last year. The company is advancing its lead compound VK2735 through Phase III trials, with both subcutaneous and oral formulations expected to enter registration trials this year. Management maintained a strong cash position of $603 million, allowing for continued investment in clinical programs and operational growth, despite a decrease from $706 million at the end of 2025.
Main topics
- Progress in VK2735 Development: Viking has made substantial progress with VK2735, completing enrollment in both the VANQUISH-1 and VANQUISH-2 trials. Management stated, "Both studies continue to proceed on track," indicating confidence in the timeline for results.
- Increased R&D Expenses: Research and development expenses surged to $115.2 million from $41.4 million year-over-year, primarily due to increased clinical study costs. This significant rise in spending raised concerns about the sustainability of cash flow.
- Introduction of Auto-Injector: Viking successfully transitioned to an auto-injector device for VK2735 in the VANQUISH studies, enhancing patient convenience. The management noted, "This transition has been proceeding smoothly," which could positively impact patient adherence.
- Oral VK2735 Phase III Initiation: The company plans to initiate Phase III trials for the oral formulation of VK2735 in Q4 2026, following positive Phase II results. Management expressed optimism, stating, "We feel good about the supply chain and the capacity and efficiencies."
- Cash Position and Financial Guidance: Viking's cash and short-term investments decreased to $603 million, but management reassured that they remain funded through 2028. They expect cash usage to stabilize, stating, "We would anticipate having cash into '28 and through the catalysts we've talked about."
Key metrics mentioned
- Net Loss: $158.3M (vs $45.6M in Q1 2025, significant increase)
- EPS: $1.37 (vs $0.41 in Q1 2025, significant increase)
- R&D Expenses: $115.2M (vs $41.4M in Q1 2025, +178% YoY)
- Cash Position: $603M (vs $706M at end of 2025, decrease of 14.6%)
- General and Administrative Expenses: $14M (vs $14.1M in Q1 2025, slight decrease)

Brian Lian
ExecutivesThanks, Stephanie, and good afternoon to everyone listening in by phone or on the webcast. Today, we'll review our financial results for the first quarter ended March 31, 2026, and review recent progress with our pipeline programs and operations. During the first quarter, we made significant progress with our obesity franchise, highlighted by our lead compound, VK2735, a dual agonist of the GLP-1 and GIP receptors. As we have previously reported, in June 2025, following the positive results from our Phase II VENTURE study, Viking initiated its Phase III VANQUISH clinical program evaluating VK2735 dosed as a weekly subcutaneous injection. The Phase III VANQUISH program includes 2 studies: VANQUISH-1 evaluating the treatment of adults with obesity and VANQUISH-2 evaluating the treatment of adults with obesity and type 2 diabetes. Enrollment in the VANQUISH-1 trial was completed in the fourth quarter of last year. And during the first quarter of 2026, we were pleased to announce the completion of enrollment in the VANQUISH-2 trial. Both studies continue to proceed on track. Also in the first quarter, the company made progress with its oral VK2735 program. Following an end of Phase II meeting with the FDA, and based on the positive top line results reported in our Phase II VENTURE-Oral dosing study, the company elected to advance oral VK2735 into Phase III clinical development, which we plan to initiate later this year. Concurrent with the planning and execution of our subcutaneous and oral registration programs in October 2025, Viking initiated a maintenance dosing study with VK2735 to assess the effect of various maintenance regimens, including monthly, every other week or weekly dosing. This [indiscernible] has advanced rapidly with enrollment completed in the first quarter of this year, less than 3 months after initiation. We expect to report the results of this study in the third quarter. Finally, in the first quarter, we filed an IND with our novel amylin receptor agonist and pending clearance are on track to initiate the clinical development of this compound later this quarter. I'll have additional comments on our operations and development activities following a review of our financial results for the first quarter ended March 31. For that, I'll turn the call over to Greg Zante, Viking's Chief Financial Officer.
Gregory Zante
ExecutivesThanks, Brian. In conjunction with my comments, I'd like to recommend that participants refer to Viking's Form 10-Q filing with the Securities and Exchange Commission, which we expect to file shortly. I'll now go over our results for the first quarter ended March 31, 2026. Research and development expenses were $115.2 million for the 3 months ended March 31, 2026, and compared to $41.4 million for the same period in 2025. The increase was primarily due to increased expenses related to clinical studies, manufacturing for our drug candidates, consultants, salaries and benefits and preclinical studies, partially offset by a decrease in expenses related to stock-based compensation. General and administrative expenses were $14 million for the 3 months ended March 31, 2026, compared to $14.1 million for the same period in 2025. The decrease was primarily due to decreased expenses related to legal and patent services and stock-based compensation, partially offset by increased expenses related to consulting, salaries and benefits and scientific and disease education. For the 3 months ended March 31, 2026, Viking recorded a net loss of $158.3 million or $1.37 per share compared to a net loss of $45.6 million or $0.41 per share in the corresponding period in 2025. The increase in net loss for the 3 months ended March 31, 2026, was primarily due to increased research and development expenses partially offset by decreased general and administrative expenses compared to the same period in 2025. Turning to the balance sheet. At March 31, 2026, Viking [indiscernible] cash, cash equivalents and short-term investments of $603 million compared to $706 million as of December 31, 2025. This concludes my financial review. And I'll now turn the call back over to Brian.
Brian Lian
ExecutivesThanks, Greg. I'll now provide an update on Viking's clinical and operational progress, beginning with our lead obesity program, VK2735. VK2735 is a dual agonist of the glucagon-like peptide 1, or GLP-1 receptor and the glucose-dependent insulin atrophic polypeptide, or GIP receptor that has demonstrated promising efficacy, safety and tolerability across multiple clinical trials. As I mentioned in my opening comments, Viking is developing both an injectable and an oral formulation of VK2735 for the treatment of obesity as well as evaluating a novel maintenance dosing protocol to support long-term weight management. During the first quarter, Viking made substantial progress in each of these areas. With respect to the subcutaneous VK2735 program, Viking's prior Phase I and Phase II trial successfully achieved their primary and secondary endpoints, demonstrating significant weight loss compared with placebo as well as an impressive safety, tolerability and pharmacokinetic profile. In the Phase I subcutaneous study, subjects receiving VK2735 achieved up to approximately 8% weight loss from baseline after 4 weekly doses with no signs of plateau. In the Phase II VENTURE study, patients demonstrated statistically significant reductions in mean body weight from baseline ranging up to 14.7% after 13 weekly doses, again with no signs of plateau. Importantly, the VENTURE study also showed VK2735 to be safe and well tolerated through 13 weeks of dosing with the majority of treatment-emergent adverse events characterized as mild or moderate and resolving quickly. These results were highlighted in a presentation at the 2025 ObesityWeek Conference last November. The final results were also published in January 2026 in obesity, the peer-reviewed Journal of the Obesity Society. Following the VENTURE Phase II study, Viking held a Type C meeting with the FDA and subsequently an end of Phase II meeting with the agency. Based on feedback from these meetings in June of last year, the company initiated the VANQUISH Phase III registration program, evaluating subcutaneous VK2735 in patients with obesity. The VANQUISH program consists of 2 clinical trials, 1 in adults with obesity and 1 in adults with obesity and type 2 diabetes. Each study is a randomized, double-blind, placebo-controlled multicenter trial designed to assess the efficacy and safety of VK2735 administered by subcutaneous injection once weekly for 78 weeks. Enrollment in each of these trials was rapid with the VANQUISH-1 study enrolling approximately 4,500 patients by November 2025, approximately 5 months after trial initiation. Enrollment in the VANQUISH-I study was completed in the first quarter, enrolling approximately 1,000 patients. Participants in each trial are being randomized to weekly doses of 7.5 milligrams 12.5 milligrams, 17.5 milligrams or placebo. Primary endpoint of the VANQUISH trials is the percent change in body weight from baseline for participants receiving VK2735 as compared to placebo after 78 weeks of treatment. Secondary and exploratory endpoints will evaluate a range of additional safety and efficacy measures, including the percentage of patients who achieve at least 5%, 10%, 15% and 20% weight loss. Each study will include an extension portion, allowing participants the opportunity to continue receiving treatment following completion of the primary dosing period, including patients who were randomized to placebo for the initial 78-week treatment period. Another important achievement during the first quarter for both the VANQUISH-1 and VANQUISH-2 studies was the successful introduction of an auto-injector device into the trials. As a reminder, both VANQUISH-1VANQUISH and VANQUISH-2 were initiated using a vial and syringe for administration of VK2735. In the fourth quarter of 2025, Viking conducted a bioequivalent study to facilitate the introduction of an auto-injector, which we believe will add optionality to treatment and may represent a more convenient method of administration for patients. This study was successfully completed. And in the first quarter of 2026, participants in both VANQUISH studies began transitioning to the auto-injector device. This transition has been proceeding smoothly, and we are very pleased to now have both VANQUISH studies advancing with our state-of-the-art auto-injector. I would now like to provide an update on Viking's oral tablet formulation of VK2735. I referenced a moment ago that we believe the auto-injector device in our subcutaneous VANQUISH studies will provide optionality and treatment. The concept of optionality is becoming increasingly important based on our conversations with physicians and KOLs about treatment regimens. Every patient's weight loss journey is unique, and we consistently hear from health care providers about the need for flexible treatment and administration options. We have long believed that an oral tablet formulation has the potential to be an attractive option for those who prefer to initiate treatment with an oral therapy or for those seeking to maintain the weight loss they have already achieved via weekly injection. Providing this optionality has been an important driver for the development of our oral program. Given the recent success of another oral peptide for obesity, we are even more optimistic about the promise of oral administration. Viking's prior Phase I and Phase II studies evaluating oral VK2735 successfully achieved their objectives, in addition to excellent safety and tolerability, our Phase I study demonstrated dose-dependent reductions in mean body weight from baseline ranging up to 8.2% after 28 daily doses. In addition, the Phase II VENTURE-Oral dosing study of VK2735 achieved its primary and secondary endpoints with participants receiving once daily doses of the tablet formulation demonstrating statistically significant reductions in mean body weight after 13 weeks, ranging up to 12.2% from baseline. Statistically significant differences compared to both baseline and placebo were observed for all doses above 15 milligrams starting at week 1 and continuing throughout the 13-week treatment period. Up to 80% of subjects in VK2735 treatment groups achieved at least 10% weight loss after 13 weeks compared with only 5% of placebo-treated subjects. The tablet formulation of VK2735 also demonstrated encouraging safety and tolerability through 13 weeks of once daily dosing. The vast majority, 98% and of drug-related treatment emergent adverse events were characterized as mild or moderate in severity. Importantly, in the dose range we plan to explore in future studies we believe the data show no meaningful difference in GI-related adverse events between subjects treated with VK2735 and placebo. The tolerability data from the VENTURE-Oral dosing study also suggests that future titration regimens, starting at lower doses and utilizing longer titration intervals are likely to further improve oral VK2735's tolerability profile. As with our subcutaneous program, following the completion of the VENTURE-Oral dosing study, we held an end of Phase II meeting with the FDA. Based on feedback from this meeting, the company plans to advance oral VK2735 into Phase III development for the treatment of obesity. We currently expect to initiate this program in the fourth quarter of this year, and we'll provide more details on study design at that time. As part of our goal to create an optimal treatment experience for patients on their weight loss journey, Viking is actively engaged with KOLs and health care providers and advocates who are focused on improving the lives of those living with obesity. Through these relationships, we have the opportunity to listen to a range of stakeholders in the community and to work towards solutions that best meet their treatment needs. Viking's efforts at developing a novel maintenance dosing strategy emerged as a result of these conversations. In approaching how the best design a maintenance study, we consider the unique characteristics of the VK2735 molecule, namely its potency and unique PK profile. We believe these features may allow the development of maintenance regimens that utilize less frequent dosing than the weekly regimens used by existing agents. This could be an attractive option for those patients who have achieved their weight loss goals and are seeking to maintain that weight loss going forward. By using the same therapeutic agent for both the induction and the longer-term maintenance phase of weight management, we believe patients may experience reduced side effects compared with options that require switching between different therapeutic agents. By reducing side effects, we believe adherence to treatment may be improved, allowing patients to ultimately realize the long-term benefits of weight loss and maintenance, including improved cardiovascular health enhanced physical function and increased quality of life. With these goals in mind, in the fourth quarter of 2025, we initiated a Phase I study to explore a range of maintenance dosing regimens. In this study, all subjects will receive initial weekly doses of VK2735, followed by a transition to a range of maintenance regimens or placebo. The objectives of the study are to evaluate the safety, tolerability and pharmacokinetic profile of VK2735 under these various regimens. Exploratory endpoints will assess the change in body weight from baseline as well as the change in body weight from the time of transition to the end of the study. The timing of this study is particularly important to our broader development program as we believe the results from these maintenance regimens could be utilized in the upcoming 52-week VANQUISH extension studies. As a result of this timing, and the importance of selecting doses for immediate use in the subcutaneous extension studies, we have bifurcated the study to focus first on the subcutaneous maintenance cohorts followed by the oral maintenance cohorts. To this end, we've expanded the number of subcutaneous dosing arms in this study from 4 to 8. This increase in cohorts will provide a broad and robust data set from which to choose for inclusion in the VANQUISH extension study. Following the completion of the subcutaneous maintenance cohorts, we will continue the study to evaluate a similarly wide range of oral cohorts. We expect to report the results of the subcutaneous portion of the study in the third quarter of this year and expect to report the oral maintenance results in the first half of next year. Moving to our other pipeline programs. Viking is also evaluating a series of novel agonists of the amylin receptor. Early data demonstrate that activation of the amylin receptor is an important potential mechanism for regulating appetite and body weight making this program an excellent addition to our obesity franchise. In 2025, we made significant progress with our lead amylin agonist VK3019, and we recently filed an IND for this program. Pending clearance, we expect to initiate a Phase I clinical trial for VK3019 later this quarter. As VK2735 advances through Phase III development and toward potential approval and commercialization, we continue to thoughtfully grow our organization to meet the opportunities and challenges that lie in the not-too-distant future. Key recent additions to our team include staffing across a range of scientific and operational roles, including supply chain management, manufacturing and quality. To coalesce these functions into an efficient and effective commercialization strategy, the company announced in the first quarter the appointment of Neil Aubuchon as its first Chief Commercial Officer. Neil brings to Viking more than 20 years of industry experience, including nearly 17 years at Eli Lilly. He has held leadership roles across global commercial and marketing functions in the cardiometabolic space, making him uniquely qualified to lead our commercial strategy for VK2735. We are excited to have him on board to lead this critical operation. As always, Viking remains vigilant in managing the company's balance sheet to ensure we're able to successfully execute our objectives. As Greg reported a few minutes ago, the company held approximately $600 million in cash at the end of the first quarter, which allows us to reach important corporate milestones, including the completion of our ongoing Phase III obesity trials as well as to pursue development of our additional programs. In conclusion, I'm happy to report that the advances and momentum of 2025 have continued through the first quarter of 2026. Looking ahead, we plan to have both our subcutaneous and oral VK2735 programs in Phase III registration trials during the year. Our maintenance dosing trial continues, and we look forward to reporting data from this study in the third quarter. With respect to our earlier stage pipeline, we expect to initiate a Phase I trial for our amylin agonist VK3019, shortly. Operationally, as our programs continue to progress toward potential approval and commercialization. Our organization continues to evolve as well. Our team is focused on executing a timely and strategic expansion plan that ensures that Viking has the partnerships, vendors and in-house expertise required to succeed in all areas including clinical, regulatory, manufacturing and commercialization. And finally, we expect to offer industry-leading options with respect to administration, dosing and maintenance that physicians and patients need to optimize the path to individual weight loss goals and long-term health. We look forward to reporting our advances on these fronts in the coming months. This concludes our prepared comments for today. Thanks for joining, and we'll now open the call for questions. Operator?
Operator
Operator[Operator Instructions] We have the first question from the line of Steve Seedhouse from Cantor.
Steven Seedhouse
AnalystsFirst is just on the change from 4 to 8 subcu maintenance cohorts in the ongoing study. I was hoping you could just elaborate on what like doses and intervals, the new 8 cohorts are testing. And then also, if you wouldn't mind just quickly commenting on R&D just for our modeling, maybe connecting the dots between the like $160 million-ish or so net loss versus about $100 million in net cash change. And I think folks specifically were expecting R&D to come down a bit this quarter from some onetime Phase III start-up costs. So I just would hope if you could clarify if you're expecting R&D cost to come down next quarter or if this is maybe the new run rate?
Brian Lian
ExecutivesThanks, Steve. This is Brian. I'll take the clinical question, and Greg will take the cash question. So on the maintenance study, just given the importance of this study for implementation into the VANQUISH extensions, we decided to extend the cohorts and then defer the oral dosing to a second part. So we'll retain those first 4 cohorts that we had earlier, which were 22.5, 20 17.5 mg monthly as well as 7.5 mg every other week. But we've added 15 monthly, 10 monthly 10 every other week and 5 every other week. So we got a nice range of every other week and a broader range of monthly doses.
Gregory Zante
ExecutivesYes. And Steve, on the OpEx and cash, for one, the disconnect on that a bit is really timing, a function of timing. They just were higher expenses and cash usage and that stuff evens out over time. But over the -- looking ahead in this next quarter, I think our cash usage and expense will be around where we were at quarter 1, maybe a bit lower. But toward the second half of this year, I would expect this to taper down a little bit. So the overall usage is still in line with our projections from our last call. And we would anticipate having cash into '28 and through the catalysts we've talked about, including the oral Phase III data points. So we remain funded as we expected, but we probably used a little bit more in the first quarter than I anticipated, but we are on track.
Operator
OperatorWe have the next question from the line of Thomas Smith from Leerink Partners.
Nathanael Charoensook
AnalystsThis is Nathanael on for Tom Smith. We have a couple of questions. So the first one now that both VANQUISH-1 and VANQUISH-2 full enrolled, what baseline characteristics are you seeing? And are they consistent with your expectations? Are you seeing any difference of enthusiasm, seen failure rates or retention between VANQUISH-1 and VANQUISH-2? And we have a follow-up.
Brian Lian
ExecutivesYes, sure. So we're actually going to present the baseline demographics at 2 conferences this year. I think in the European Congress of obesity, we'll have the VANQUISH-1 demographics. And then at EASD, we'll have VANQUISH-2 demographics. So I'll defer to those conferences for the demographic disclosures. But I don't think anything is kind of out of the ordinary with respect to the population relative to other studies that are kind of down the middle of the fairway.
Nathanael Charoensook
AnalystsGot it. Yes. And the second one, how should investors think about the expected weight loss in type 2 diabetic versus nondiabetic OBC patients?
Brian Lian
ExecutivesYes. Hard to know. It's obviously the individual investor to make that estimation. But generally, type 2 patients are a little bit more resistant to weight loss than non-type 2 patients. So I don't think that would be surprising to see in the weight loss data from these studies. I think probably see more robust effect in the straight obesity and maybe a little bit lower efficacy in type 2 diabetics, just like everybody else has shown.
Nathanael Charoensook
AnalystsAnd finally, on the Phase II initiation of oral VK2735, which is now expected in 4Q '26, what changed versus prior expectation for [ 2226 ].
Brian Lian
ExecutivesNothing really changed. We're moving incredibly fast and scaling up dramatically here. And as you do that, you learn a lot about the process and efficiencies, making 100 tablets is different than making 1 million tablets. And so you learn a little bit more about engineering processes and et cetera, that get optimized along the way just to ensure you got the most efficient and cost-effective methods in place. And all of that takes some time. We feel good about the supply chain and the capacity and efficiencies and where we're at in the development cycle. So I look forward to initiating as early as possible in the fourth quarter.
Operator
OperatorWe have the next question from the line of Mike Ulz from Morgan Stanley.
Michael Ulz
AnalystsMaybe just a follow-up on the maintenance study. Obviously, you're testing a number of different regimens, subcu, oral, et cetera. Just curious, early in the study, if you're getting a sense of which one of those options that's sort of resonating most with the patients? And could it be the monthly dosing? Or is that a wrong interpretation?
Brian Lian
ExecutivesYes, we're not really getting that level of feedback, Mike, and it would be hard to interpret because it's a placebo-controlled study. But we made the addition of the subcu cohorts before anybody had transitioned to the maintenance setting. So no one had actually entered into the oral maintenance portion. We made the decision and expanded the subcu portions. We'll do the oral then in a separate part of the study.
Operator
OperatorWe have the next question from the line of Ryan Deschner from Raymond James.
Ryan Deschner
AnalystsWhat were the key factors that went in selecting the 19-week period as the subcu induction time period for the maintenance study? And then I have a follow-up.
Brian Lian
ExecutivesYes. Thanks, Ryan. It was really driven by the time to titrate to the 22.5 mg dose. That was the highest dose, and we wanted to put people -- first get people up there and then keep them there for I think it's a 3-week treatment time there and then transition everybody to the maintenance at the same time point. So that was sort of the rate-limiting factor, the time it took to titrate to the highest dose.
Ryan Deschner
AnalystsGot it. That's helpful. And I guess I just wanted to kind of feel out what the odds might be. Would you add an additional oral cohorts potentially later on in the maintenance study. Is that something that could be on the table?
Brian Lian
ExecutivesYes, absolutely. Great question. Yes, we will be adding more cohorts to the oral portion of the study. So we'll probably look at a few more doses as well as potentially alternative regimens.
Operator
OperatorWe have a next question from the line of Anna Samimy from Stifel.
Annabel Samimy
AnalystsSo obviously, with the addition of new cohorts or maintenance studies seems to have gotten a little bit more involved. And I guess I'm trying to figure out what the various possibilities are for that extension trial? Are you going to select 1 of these cohorts? Are you going to give the option for multiple cohorts going into the extension study? Like what is the purpose of having all these 8 additional cohorts. I'm just trying to understand exactly what you intend to do with these cohorts going forward? Is it just for information purposes and their selection in the extension study? And then I guess taking it forward, are you going to develop it any further past this extension study for possible inclusion in the label? Or is it just developing a wealth of data for physicians to draw and sort of use the data as an art rather than a very prescriptive formula for maintenance for these patients.
Brian Lian
ExecutivesYes. Thanks, Annabel. Two great questions. I think with the second question, at a minimum, we would hope to be able to publish the extension data from the VANQUISH extension, utilizing some of these maintenance cohorts. So that would provide valuable information in the form of publications to clinicians and patients. And what do we expect to learn from the maintenance cohorts? So really, the best maintenance strategy to employees is every other week dosing preferable. It seems like a lot of people are doing that now just out in the real world. is monthly going to be the better strategy. And if so, what dose. And so we had only 3 monthly doses and 1 every other week dose in the prior study. And so we thought to better inform the cohorts that would go into the extension of VANQUISH, and there will be more than 1 dosing arm in the extension studies for maintenance and Vanquish. It just made sense to expand the subcu cohorts and then defer the oral since we went as time sensitive on the oral to a separate part of the study.
Annabel Samimy
AnalystsOkay. Got it. So just to clarify, you will have a very defined set of cohorts in that extension study. Drawing from this data, the Phase I data?
Brian Lian
ExecutivesOh, sure. Yes, definitely. It will be multiple maintenance cohorts there that will be drawn from these data. Yes. Thanks, Annabel.
Operator
OperatorWe have the next question from the line of Biren Amin from Piper Sandler.
Biren Amin
AnalystsBrian, I guess just on the VANQUISH expansion, when will the maintenance doses be introduced for the subcu? Will that be at week 78 or week 84? And how long will you be evaluating those subcu doses? And I guess just a follow-on question for the VANQUISH dose cohorts in the treatment phase of 7.5 and 12.5 weekly, how do you think about the transition of those patients to maintenance doses given the maintenance trials evaluating 15 milligrams weekly and higher in that 19-week induction period.
Brian Lian
ExecutivesYes. Well, we'll -- for the first question, we'll transition people at 78 weeks won't be a sort of a washout or anything like that out and we plan to run the extension for 52 weeks. As far as the transition from $17.5 million to whatever the maintenance dose might be. Yes, if you were to go from 17.5% to a higher 22.5 mg dose or something like that, there could be some incremental adverse events. That's not really what you see after a prolonged exposure like this, but those are all the things that we'll find out during the trial. Thanks, Biren.
Operator
OperatorWe have the next question the line of Jay Olson from Oppenheimer.
Jay Olson
AnalystsCongrats on all the progress. Just a follow-up on some of the factors that informed your decision to initiate the Phase III oral study in the fourth quarter. Did you want to see the results of the Phase I maintenance study in the third quarter before starting the Phase III oral study in the fourth quarter? Or were there other factors involved -- and then we also had a question on 3019. Could you just talk about your plans for the Phase I amylin program? Are you thinking about induction, maintenance combination, I guess, what's kind of on the table there for your amylin program.
Brian Lian
ExecutivesYes. Thanks, Jay. For the oral study, no, we weren't planning to wait for the data. They're just independent factors, the maintenance data and the initiation of the oral studies that were not related. With the 3019 molecule, the first study will be -- before you think about combos and that sort of thing, first, you want to understand the compounds basic properties. And so the first 2 studies will be a SAD study and then a MAD study. We are initiating combo talks with the 2735 compound. So longer term, I think that's a really promising area to look at. But the initial studies will just be single agent. And it would be kind of the playbook we used for 2735 with a [indiscernible] followed by a 28-day mat. Nice opportunity with this mechanism to potentially target people who are a little lower BMI, 32 to 34, 35 or people who can't maybe can't tolerate the GLP-1 and want to try something different, but both are very significant opportunities for the amylin program.
Operator
OperatorWe have the next question from the line of Andy Hsieh from William Blair.
Tsan-Yu Hsieh
AnalystsJust for the extension portion of the VANQUISH study, I'm curious about maybe the patient's ability to select just given the open-label nature of the study? And also do you allow patients to maybe down titrate if you're they're at a higher monthly dose or up titrate if they actually see like a weight regain -- just maybe from a practical protocol-related nation.
Brian Lian
ExecutivesYes. Thanks, Andy. Great question. It's not really an open-label study. And so people -- if you were on placebo, you will be randomized to active agents, but you don't know which dose level you'll be at -- and we're not going to, I think, discuss many design details otherwise until we actually start the study, but you can imagine some people staying on their current therapy and some people transitioning maybe to a maintenance regimen. So different groups of people might be randomized to different cohorts. I think it's a very elegant and nice study design, but we probably won't discuss too many details until we actually start it. Thanks, Andy.
Operator
OperatorWe have the next question from the line of Roger Song from Jefferies.
Jiale Song
AnalystsGreat. To put a final point on the VANQUISH extension regimen from the maintenance data you will report. I understand that you want to expand every 2 weeks dosing. And then is that fair to say you want to pick 1 monthly on for every 2 weeks. And how much delta among those dosing regimens you will take multiple within those 2 frequency?
Brian Lian
ExecutivesThanks, Roger. Yes. So I think more generally, we want to select the most effective arms and doses. So not wedded to a certain number of every other week or a certain number of monthly just whatever seems to be the most effective. So we would look at multiple arms to come forward, and those will be based on whatever seems to look best in this initial 102 maintenance study. Thanks, Roger.

OperatorWe have the next question from the line of William Wood from B. Riley Securities.
William Wood
AnalystsVery nice progress you've been making. So two from us, one upfront and then a follow-up. I'm just curious in terms of your maintenance trial with the additions of the new subcu and then also it sounds like the new additions of the oral. Should we expect any delay in timing throughout the third quarter, maybe from the beginning to the end and/or should we expect sort of multiple data cuts throughout the third quarter in terms of whether it's at the 19-week and then the final maintenance or we'll get the subcu first and then the oral. Maybe just if you could clarify on that? And then I have a follow-up.
Brian Lian
ExecutivesYes. Thanks, William. It will probably be 2 data releases, 1 for the subcu cohorts and then subsequently for the oral cohorts. But the subcu will be in the third quarter, and we don't anticipate there being a substantial difference in the timing for the data to be available. Maybe a little bit, but nothing significant.
William Wood
AnalystsRight. That's very helpful. And then on your VK3019. You've mentioned in the past that, that asset has shown better efficacy or potentially weight loss than your 2735, at least preclinically. I was curious if you could provide some of those comparative parameters of the 2 drugs, maybe Cmax, Tmax or half-life or even weight loss understanding it all be preclinical and how this might have compared to tirzepatide or even per amylin, if you've done any of those studies. Just sort of trying to get a better understanding of what stood out on this particular asset that decided for you to bring it to the clinic.
Brian Lian
ExecutivesYes. Thanks, William. Yes, unfortunately, I don't carry a lot of those data around in my head. There's too much other junk up there. But it was very potent on the receptors, very good PK profile that would be amenable to weekly dosing, we think, and that marries up nicely with the 2735-PK profile. When we looked at data in rodents, it seemed to be better than cagrilintide. When we looked in obese monkeys, it seemed to provide better weight loss than VK2735.But I don't have those numbers off the top of my head, these are just general comments. Thanks, William.

OperatorWe have the next question from the line of Hardik Parikh from JPMorgan.
Hardik Parikh
AnalystsJust a couple of questions on the oral program. So just one is I know in the past, you've talked about you're working on reducing the number of tablets you have to take at a dose. I was wondering if you have any updates there on where you are in that progress? And then just a high-level question on -- you mentioned the launch of another oral peptide -- just what are you -- how are you -- where do you think the takeaways from that launch in terms of just what it says about the overall market and then the role of oral peptides in general?
Brian Lian
ExecutivesYes. Thanks, Hardik. So we would want to have no more than 2 tablets as the higher dose option lower doses would be 1 tablet. So in the Phase II trial, everybody took 4 tablets and the feedback we received was that's just people weren't real satisfied with that -- so no more than 2 tablets. And we generally don't comment too much about competitive dynamics. But I think the launch of the current oral peptide has been very robust, and it supports this real, I think, high interest level in the oral modality. And interestingly, it's represented more of a market expansion than any sort of cannibalization of the injectable market. So it's been, I think, a very, very impressive launch. And Neil Aubuchon is our Chief Commercial Officer. He's here as well. Neil, do you have any additional color on that?
Neil Aubuchon
ExecutivesYes. Brian, I think you characterized it well, Hardik, this is Neil here. Yes, I think what we're seeing is this is growing the market. So it just goes to show that there's significant opportunities still -- it's too early to comment on the latest launch. I think it's just several weeks in. So we wouldn't have commented in any way, but it's awfully early. It's going to be quite competitive dynamic between these 2 companies, as you would expect. The only thing I would also just remind you is that both the orals on the market are GLP-1s, where ours is going to be a dual agonist oral. So we expect to have the first dual agonist oral on the market. And I don't know if that's fully appreciated by folks in the ecosystem. So we're pretty excited about the opportunity for oral. Thanks, Hardik.

OperatorWe have a next question from the line of Yale Jen from Laidlaw & Company.
Yale Jen
AnalystsIn terms of the VANQUISH expansion study, would that also include both VANQUISH-1 and VANQUISH-2 in terms of the type 2 diabetes patients as well as if you will incorporate some maintenance regimen into those -- in that study, would that also include type 2 diabetes patients as well.
Brian Lian
ExecutivesYes, it will. Yes.
Operator
OperatorOur final question will come from Jeet Mukherjee from BTIG.
Unknown Analyst
AnalystsThis is [ Blake ] on for Jeet. In regards to the subcu maintenance data coming in the third quarter, what does good look like to you guys in -- are you comfortable reporting a modest [indiscernible]? If so, is there a BARDA standard that qualifies as weight to retention?
Brian Lian
ExecutivesYes. Thanks, Blake. It's a good question. I guess the way we look at it is best case scenario is you see a continuation of weight loss when you transition to the maintenance regimen, just slope might change a little bit. I think our base case is -- which is a great outcome. It's just a real maintenance, less than really a few percent either way up or down. And then the worst case would be you see a sharp rebound. So those are kind of the general scenarios that we're looking at. And I think a flat lining or relatively flat after the transition would be a really great outcome for us.
