Welcome to the Viking Therapeutics twenty twenty one Fourth Quarter and Year End Financial Results Conference Call. At this time, all participants are in a listen only mode. Following management's prepared remarks, we will hold a Q and A session. As a reminder, this conference call is being recorded today, 02/09/2022. I would now like to turn the conference over to Viking's Manager of Investor Relations, Stephanie Diaz.
Please go ahead,
Speaker 1
Hello, and thank you all for participating in today's call. Joining me today is Brian Lian, Viking's President and CEO and Greg Zanti, Viking's CFO.

Speaker 2
Thanks, Stephanie, and thanks to everyone dialed in by phone or listening on the webcast. Today, we'll review our fourth quarter and full year 2021 financial results and provide an update on recent developments and progress with our pipeline programs and operations. 2021 was a very productive year for Viking. During the year, we continued to make progress with our lead program VK2809 currently in a Phase 2b study for patients with biopsy confirmed NASH and fibrosis, opening additional clinical trial sites and continuing enrollment of new patients. We expect to complete enrollment of this trial and report top line data by year end.
In 2021, we also reported data from the first in human study of VK0214, our second thyroid receptor beta programming program, demonstrating the compound's impressive safety, tolerability, and preliminary lipid lowering effects. Following completion of the first in human study, we initiated a Phase 1b study in patients with X linked adrenoleukodystrophy, a rare neurodegenerative disease for which there is no cure. We were recently informed that the FDA has placed this study on clinical hold pending completion of an additional preclinical study, and we expect to submit the results of this study in the second quarter. Finally, in recent months, we expanded our clinical pipeline with the addition of a new internally developed program targeting the GLP-one and GIP receptors for metabolic disorders. We reported two posters from this program at ObesityWeek in November, and last month announced the initiation of a first in human study of our lead compound VK2735.
I'll have more to say about these programs in a few minutes, but I'd like to highlight as we reflect on the past twelve to eighteen months that Viking has transformed over the past several quarters from a company with one clinical program to a company with three active clinical programs across a diverse range of indications with important data inflections for each expected in the next twelve to eighteen months. The breadth and depth of our clinical and preclinical pipeline represents an important progression from a single program story into a diversified biopharmaceutical company with programs advancing in multiple important indications. We are proud of the progress we've made and see the last twelve months as providing an important base from which we will advance multiple programs into late stage development. I'll provide further detail on our operations and development activities after we review our fourth quarter and year end financial results. For that, I'll turn the call over to Greg Ganti, Viking's CFO.
Speaker 3
Thanks, Brian. In conjunction with my comments, I'd like to recommend that participants refer to Viking's Form 10 ks filing with the Securities and Exchange Commission, which we expect to file this week. I'll now go over our financial results for the fourth quarter and full year ended 12/31/2021, beginning with the results for the quarter. Our research and development expenses for the three months ended 12/31/2021 were $9,800,000 compared to $9,000,000 for the same period in 2020. The increase was primarily due to increased expenses related to manufacturing for the company's drug candidates, preclinical studies, stock based compensation, salaries and benefits and services provided by third party consultants partially offset by decreased expenses related to clinical studies.
Our general and administrative expenses for the three months ended 12/31/2021 were $2,700,000 compared to $2,200,000 for the same period in 2020. The increase was primarily due to increased expenses related to salaries and benefits, stock based compensation and insurance, partially offset by decreased expenses related to legal services. For the three months ended 12/31/2021, Viking reported a net loss of $12,400,000 or $0.16 per share compared to a net loss of $10,900,000 or $0.15 per share in the corresponding period in 2020. The increase in net loss and net loss per share for the three months ended 12/31/2021 was primarily due to the increase in research and development expenses and general and administrative expenses noted previously as well as decreased interest income primarily due to the decline in interest rates available throughout the 2021 as compared to prevailing interest rates available during the same period of 2020.
Speaker 4
I'll now go over
Speaker 3
the results for the full year 2021. Our research and development expenses for the full year ended 12/31/2021 were $45,000,000 compared to $31,900,000 for the same period in 2020. The increase was primarily due to increased expenses related to clinical and preclinical studies, manufacturing for the company's drug candidates, services provided by third party consultants and stock based compensation, partially offset by decreased expenses related to salaries and benefits. Our general and administrative expenses for the full year ended 12/31/2021 were $10,700,000 compared to $10,700,000 for the same period in 2020. This was primarily due to decreased expenses related to salaries and benefits and legal services offset by increased expenses related to insurance, professional fees, services provided by third party consultants and stock based compensation.
For the full year ended 12/31/2021, Viking reported a net loss of $55,000,000 or $0.71 per share compared to a net loss of $39,500,000 or $0.54 per share in the corresponding period in 2020. The increase in net loss and net loss per share for the year ended 12/31/2021 was primarily due to the increase in research and development expenses noted previously as well as decreased interest income primarily due to the decline in interest rates available throughout the year ended 12/31/2021 as compared to prevailing interest rates available during the year ended 12/31/2020. Turning to the balance sheet. At 12/31/2021, Viking held cash, cash equivalents and short term investments totaling $202,100,000 compared to $248,400,000 as of 12/31/2020. This concludes my financial review and I'll now turn the call back over to Brian.
Speaker 2
Thanks, Greg. As I mentioned in the opening comments, Viking has recently expanded its clinical pipeline and in doing so we have strengthened our commitment to the development of novel therapeutics for the treatment of metabolic diseases. Since the company's founding, we have advanced into clinical development two metabolic drug candidates that we believe represent best in class status in the case of our lead candidate VK2809, and first in class status in the case of our second clinical candidate VK0214. We believe that these programs, together with our expertise in metabolic diseases, places us in a leadership position in the development of next generation therapies for a range of metabolic disorders. This is exemplified by our recent introduction of VK2735, an exciting new program with the potential to advance in multiple indications.
I'll now provide an update on each of these programs beginning with our lead program VK2809. As a reminder, VK2809 is an orally available small molecule agonist of the thyroid hormone receptor that is selected for the liver as well as the beta isoform of the thyroid hormone receptor. The prior twelve week phase two a study evaluating VK2809 in patients with nonalcoholic fatty liver disease and hypercholesterolemia successfully achieved both its primary and secondary endpoints. Patients receiving VK2809 at doses as low as five milligrams daily demonstrated highly statistically significant reductions in liver fat content as well as improvements in LDL cholesterol. VK2809 also performed well on secondary measures in this study demonstrating significant reductions in other plasma lipids such as triglycerides, apolipoprotein B, and lipoprotein A.
In addition, patients treated with VK2809 in this study experienced durable reductions in liver fat with the majority of patients remaining responders four weeks after completion of dosing. This study also demonstrated the promising safety and tolerability profile of VK2809. Patients treated with VK2809 reported lower rates of GI disturbances such as diarrhea or nausea compared with patients receiving placebo. In addition, no serious adverse events were reported among patients receiving VK2809 or placebo. Combined, we believe these features establish VK2809 as a best in class compound for the potential treatment of patients with NASH and fibrosis.
It is also important to note that the compound's lipid lowering effects may lead to improved cardiovascular benefits, a significant advantage when compared to other drugs and competitive mechanisms in development that have been shown to increase plasma lipids. Based on the promising findings from our phase 2a study, we initiated a phase 2b study to evaluate VK2809 in patients with NASH. This trial called Voyage is a randomized double blind placebo controlled multicenter trial designed to assess the efficacy, safety, and tolerability of VK2809 in patients with biopsy confirmed NASH and fibrosis. The study is enrolling patients across five treatment arms, and the target population includes patients with at least 8% liver fat by MRI PDFF, as well as F2 and F3 fibrosis. Up to twenty five percent of enrolled patients may have F1 fibrosis so long as they possess at least one additional risk factor.
The primary endpoint of the study will evaluate the change in liver fat content as assessed by magnetic resonance imaging proton density fat fraction from baseline to week twelve in patients treated with VK2809 as compared to patients receiving placebo. Secondary objectives include the evaluation of histologic changes assessed by hepatic biopsy after fifty two weeks of treatment. During the fourth quarter, enrollment in the VOYAGE study continued at sites in The U. S. And abroad.
We expect to complete enrollment and report the initial data from this study by the 2022. I'll now provide an update on VK0214, our second orally available small molecule thyroid hormone receptor beta agonist in clinical development. VK0214 is currently in development for the treatment of X linked adrenoleukodystrophy or X ALD. X ALD is a rare and often fatal metabolic disorder characterized by a breakdown in the protective barrier surrounding brain and nerve cells. The disease for which there is no FDA approved therapeutic is caused by mutations in a gene known as ABCD1, which encodes a peroxisomal transporter of very long chain fatty acids.
As a result of mutations, transporter function is impaired, and patients are unable to efficiently metabolize very long chain fatty acids. The resulting accumulation of these compounds is believed to contribute to the onset and progression of clinical signs and symptoms in patients with X ALD. Interestingly, the thyroid hormone beta receptor has been shown to stimulate the expression of an alternative very long chain fatty acid transporter encoded by a gene known as ABCD2. Multiple preclinical models have demonstrated that increased ABCD2 expression can lead to improved and potentially normalized very long chain fatty As VK0214 has demonstrated a potent activation of the thyroid hormone beta receptor, we believe that it may also represent a potential approach to the treatment of XALD.
Last summer, we reported the results of a randomized, double blind, placebo controlled, single ascending and multiple ascending dose study of VK0214 in healthy volunteers. The objectives of the study were to evaluate the safety, tolerability, and pharmacokinetics of VK0214 administered orally once daily for up to fourteen days. This study successfully achieved its primary and secondary objectives with VK0214 shown to be safe and well tolerated at all doses evaluated. Among the more than 100 subjects enrolled in this study, no serious adverse events were reported. And no treatment or dose related trends were observed for vital signs or cardiovascular measures.
No gastrointestinal disturbances such as diarrhea or nausea were reported at doses up to and including the top dose of one hundred and twenty five milligrams. Treatment with VK0214 demonstrated dose dependent exposures, no evidence of accumulation, and a half life consistent with anticipated once daily oral dosing. Subjects who received VK0214 experienced reductions in LDL cholesterol, triglycerides, apolipoprotein B, and lipoprotein A following fourteen days of treatment. Many of the observed lipid reductions achieved statistical significance, though the study was not powered to demonstrate statistical significance on laboratory assessments. As a result of these findings, we initiated the phase 1B study of VK0214 in patients with the adrenal myeloneuropathy or AMN form of X ALD.
AMN is the most common form of X ALD affecting approximately fifty percent of those with the disease. Clinical manifestations include progressive leg weakness, incontinence, and sexual dysfunction. Our Phase 1b study is a multicenter, randomized, double blind, placebo controlled study in adult male patients with AMN. The study is initially targeting enrollment across three cohorts, placebo, VK0214 dosed at twenty milligrams daily, and VK0214 dosed at forty milligrams daily. Pending a blinded review of preliminary safety, tolerability, and pharmacokinetic data, additional dosing cohorts may be pursued.
The primary objectives of the study are to evaluate the safety and tolerability of VK0214 administered once daily over a twenty eight day dosing period. In addition, the study includes an exploratory assessment of the impact of VK0214 on plasma levels of very long chain fatty acid, as well as an evaluation of the pharmacokinetics of VK0214 in these patients. Last month, we were informed that this trial has been placed on clinical hold by the FDA. The agency has requested completion of an additional preclinical study prior to continuation. This request is not due to any findings from ongoing or previously completed studies.
Rather, the FDA informed us that it considers the ongoing trial to be a Phase II trial rather than a Phase Ib. As a Phase II trial, FDA guidance requires that a rodent genotoxicity study is completed prior to initiation. We expect to complete the study and submit the requested information in the second quarter with a goal of resuming dosing in the study later this year. We are confident in the overall safety and potential efficacy profile of VK0214 to date. And while a short term delay is anticipated, we do not expect the long term development timeline for VK0214 to be significantly impacted.
I'll now provide an overview of the newest addition to our clinical pipeline, an internally developed program targeting dual agonist of the glucagon like peptide one or GLP-one and the glucose dependent insulinotropic peptide or GIP receptors. We believe these compounds represent an exciting therapeutic opportunity. In recent years, multiple GLP-one receptor agonists have been approved for the treatment of both diabetes and obesity due to their ability to improve insulin sensitivity, lower plasma glucose, and reduce overall body weight. More recently, research has focused on developing combination therapeutics designed to maintain potent activation of the GLP-one receptor while also activating other important receptors related to metabolic control. The benefits of simultaneous activation of the GLP-one and GIP receptors are of particular interest to Viking.
The GIP receptor is known to regulate insulin secretion and to provide modest activation of the glucagon receptor. A single molecule with combined activity at both the GLP-one and GIP receptors may therefore provide improved metabolic benefit relative to activation of either receptor alone. Recent clinical data have borne this out, demonstrating that dual GLP-one GIP agonists not only provide excellent glucose control, but also potent reductions in body weight. Some time ago, we initiated an exploratory program targeting novel dual agonists of the GLP-one and GIP receptors. We are pleased with our early findings from this program, which we shared for the first time last November at ObesityWeek, the annual meeting of the Obesity Society.
At this meeting, we presented two posters highlighting the improvements in metabolic profile observed among diet induced obese mice treated with R compounds as compared to control cohorts. Weight loss, glucose control, and insulin sensitivity were enhanced following treatment with our dual agonist compared to the effects observed with the GLP-one mono agonist semaglutide when administered at the same dose for the same time period. These results suggest that the addition of GIP receptor activity improves upon the effects achieved with activation of the GLP-one receptor alone. Reductions in liver fat were generally numerically larger among animals treated with our compounds relative to liver fat reductions observed among animals treated with semaglutide. Based on the results of these and other preclinical studies, we selected VK2735 as the lead candidate from our dual agonist program, and we announced last month the initiation of a Phase I trial evaluating VK2735 in healthy volunteers.
The phase one trial is a randomized, double blind, placebo controlled, single ascending and multiple ascending dose study in healthy adults. The primary objectives of the study include evaluation of the safety and tolerability of single and multiple ascending dose studies of VK2735 delivered subcutaneously as well as the identification of doses suitable for further clinical development. Study investigators will also evaluate the pharmacokinetics of VK2735 following single and multiple doses. Exploratory pharmacodynamic assessments include evaluations of changes in body weight and liver fat content after four weeks of once weekly administration. We are encouraged by the preclinical data from this program and excited to be moving forward with clinical development of this important compound.
Finally, to support our expanded pipeline, we continue to carefully manage our cash. As Greg noted earlier, we ended the year with over $200,000,000 in cash. We believe this provides us with the resources to complete our ongoing clinical studies and advance our programs well into later stage development. I'll conclude by reiterating some of my opening comments, highlighting that the past twelve to eighteen months have been especially productive at Viking. The company has transformed from having a single compound in active clinical development to a company that now has three active clinical programs as well as additional preclinical programs underway.
Our near term focus remains on our most important program VK2809 for NASH, where we expect to complete enrollment in the Phase IIb VOYAGE study and report initial data by year end. Our longer term focus has expanded to include the development of VK0214, where we expect to resume clinical development later this year for the treatment of X ALD. In addition, our newest program, VK2735, is now in a first in human study with data expected by year end. We believe this new program creates multiple opportunities for future development, and we look forward to sharing those plans as the program matures. As with the rest of our pipeline, the early data from VK2735 indicate the potential for a best in class compound addressing metabolic indications.
Our pipeline is more diverse than ever, and our expanding platform allows us to focus on programs targeting large indications such as NASH, as well as orphan indications such as X ALD. And we have now advanced an internal preclinical asset into a clinical development program with significant potential. We look forward to advancing each of these programs as well as continuing to evaluate novel early stage opportunities targeting metabolic diseases. This concludes our prepared comments for today. Thanks again for joining us and we'll now open the call for questions.
Operator?

We will now begin the question and answer session. Our first question comes from Steve Seedhouse with Raymond James. Go ahead.
Speaker 4
Oh great. Thanks so much for taking the question. Brian, I was just hoping you could clarify in the two fourteen study given the hold, just how far along were you into patient enrollment and treatment? And are you able to as you resolve that with the assay that the FDA is requiring, are you able to continue to screen patients and sort of keep sites online such that you won't have too much of a disruption?
Speaker 2
Hey, Steve. Thanks for the question. So we will keep sites online. We're not shutting any sites down. But the hold does not allow us to continue screening or enrolling patients.
I think one thing that will mitigate a potential delay is that we're also moving to open sites in Europe, and, we expect those sites to come online around midyear. And so if that aligns with the potential reopening of the study, we think that that would help mitigate some of the slowdown here. But there's no shutting down of any sites at this time.
Speaker 4
Okay, thanks. And just separately, and I know obviously the hold isn't related to, you know, the emerging data from Phase one, but I just had a question because it got me thinking about just the safety margin for this drug and, you know, the the when you think about it in the context of legacy TR beta agonists that weren't, liver directed and, you know, the doses that you're using in the study, how confident are that that you've seen impact on on, you know, very long chain fatty acids already? How confident are you that you're going have a wider safety margin than some of those legacy drugs that had problems?
Speaker 2
Yes, it's a good question. So we look at the phase one data, we didn't see any effect on any cardiovascular measures. And so no change to heart rate or blood pressure or anything like that. And so that would be, you know, one sign of potential thyroid alpha activation. And as far as like the dose level, we don't think we have to go all the way up as high as we went to the in the single or the multiple ascending dose portion.
We think, when you look at the lipids sort of plateauing around, you know, twenty to fifty milligrams, we think that the XALD study won't have to push as high as we did in the, multiple ascending dose study, which should help, as well. And then finally when we, you know, look at the data so far from the tox studies we don't see any significant effect on the target tissues that you would want to watch out for and that's bone and cardiovascular system. So far so good. But it's still relatively early development.
Speaker 4
All right. Thanks for the thoughts, everyone. Appreciate the question.
Speaker 2
Thanks, Steve.
Speaker 0
The next question comes from Joon Lee with Truist Securities. Please go ahead.
Speaker 5
Good afternoon. This is Les on for June. Congratulations on the progress and thank you for taking my questions. First on the NASH program, can you just kind of provide an update on the enrollment? And has the enrollment improved and catching up to your internal timing targets?
And what is the earliest we could expect to see the twelve week data?
Speaker 2
Yes. Thanks, Les. So we haven't really given patient by patient enrollment updates historically. But I would say, you know, in the first part of the year, enrollment has picked up a little bit relative to the 2021. And I'll caveat that by saying, you know, you typically see a lag in the screening pipeline to patients actually enrolled.
So, you know, any effect on the trial from Omicron probably won't be felt right away. But enrollment has ticked up slightly in the first part of the year. And we've not given a lot of granularity. We've just guided to completion of enrollment and the initial twelve week data by the end of the year.
Speaker 5
Got it. That is helpful. And then just my follow-up regarding the dual agonist program and congrats on the selection. I just wanted to see if you have any supporting endpoints that you'd be looking for in determining indication selection? And if it is a large indication, at what stage of the program would you consider partnering discussions if you do decide to partner on that?
Thank you.
Speaker 2
Yeah, sure. So the multiple ascending dose portion of that study is going to be four weeks long. And so it's a little short to get a good handle on efficacy and to, you know, first in human study anyway. But we will be looking at, you know, plasma glucose. We'll look at insulin.
We'll look at body weight. We'll look at liver fat content. So a lot of different metrics that would help direct the program in future studies. But it is, you know, pretty short, so all those reads will be preliminary. Thank you.
Thanks, Wes.
Speaker 0
The next question comes from Joe Pantginis with H. C. Wainwright. Please go ahead.
Speaker 4
Hey, everybody, good afternoon. Thanks for taking the question. Brian, I guess when you have all these programs going and you're still enrolling Voyage, I want to talk about the overall running of Viking. And I guess overall, the industry is facing a lot of, headwinds right now. And, you know, I guess, wanna ask how agile or if, how agile you've been with regard to, you know, dealing with supply chain constraints, preparing for manufacturing, you know, above and beyond what you usually might have, anything that you might have been able to, you know, go above and beyond that you usually would not have.
Speaker 2
Yeah, thanks Joe. It's an interesting question. You know, the pandemic has affected a lot of things in a lot of different ways. And what we've noticed in particular is, you know, with clinical sites and with CROs is staffing issues are a consistent problem that we hear about when we never heard about prior to the pandemic. And so maintaining staff, you know, a turnover lot at CROs more than you would anticipate.
And what we've done is tried to, to the extent possible, try to plan ahead a little bit better. We have noticed some of the queues for manufacturing, for preclinical studies, for in vivo studies. The queues are longer than they were prior to the pandemic, so it it makes you have to decide a little earlier and and and try to get in queues earlier. Hopefully, all of this will normalize, but it is, these little ripple effects are they're a challenge.
Speaker 4
Understood. Thanks a lot.
Speaker 2
Thanks, Joe.
Speaker 0
The next question comes from Jay Olson with Oppenheimer. Please go ahead.
Speaker 6
Hey,
Speaker 7
Brian. Thanks for the update and thanks for taking the question. Can you talk about what level of MIPDFF liver fat reduction at twelve weeks you'll be looking for in the VOIDGE study and what's sort of your benchmark there and what would be clinically meaningful? And then maybe related to that are there any competitive dynamics in NASH that you've been watching and new data that you're interested in and also any new mechanisms on the horizon that you're excited about especially anything that could be used in combination with 2809? Thank you.
Speaker 2
Yeah, thanks Jay. So I think the hurdle that we're most focused on is that responder hurdle, the 30% fat reduction, relative reduction in liver fat content, because that's really the only hurdle that has been talked about or established with respect to improving the odds of a histologic benefit. So if we can see most of our patients being characterized as responders, we think that would improve the odds of NASH resolution and we think also improve the odds of seeing some improvement in fibrosis. Anything above that would be great, but, that's what we're hoping for initially. We saw quite a bit better than that in the twelve week study.
As far as the competitive landscape, it's a rich competitive landscape. We're comfortable with the competitive profile with the safety and tolerability and efficacy that we've seen so far. I think the molecule is great and the effect on lipids is a clear differentiator versus other mechanisms. So reducing atherogenic proteins, as I said in the prepared comments, it's a real benefit that you don't see necessarily with other mechanisms. I think the mechanisms that are most intriguing to us are the ones that improve insulin sensitivity and also have direct impacts on body weight and liver fat.
And that's those things on the incretin axis, GLP-one, GIP, where we're also involved with the dual agonist. So we really like that axis and as far as combinations that might be an attractive way to position a combination therapy with a thyroid agonist. Super helpful. Thanks Brian. Thanks Jay.
Speaker 0
The next question comes from Alex Ramsey with William Blair. Please go ahead.
Speaker 8
Hi Brian, this is Alex on for Andy.
Speaker 0
I got a couple of
Speaker 8
questions related to Prader Willi syndrome which you mentioned being potentially interesting indication for VK280735. So the questions that I have are first, if you could give us a sense of the overall market size of the indication and how much of it Viking might be able to capture? And then second, what kind of results or benchmarks would you be looking at in the earlier stages of the clinical trials to give confidence that Crater really might be an interesting indication to pursue? And then finally, was wondering what kind of defined developmental or regulatory pathways there are for this indication?
Speaker 2
Yeah, thanks Alex. I appreciate the questions. So we're still pretty early in the learning curve for Prader Willi syndrome. We think the mechanism to the extent these patients have this hyperphagia uncontrolled appetite, the dual activity of GLP-one and GIP in the hypothalamus might be really, really beneficial for this population in mitigating, you know, appetite. And to the extent that we can, control, you know, insulin sensitivity, plasma glucose, that sort of thing, which many of these patients suffer from, I think that's an added benefit and something that we think could really help, this population.
When we look at case studies, the GLP-one agonists seem to have some benefits in some of these patients. So the addition of the GIP receptor should be helpful as well. As far as the market side, you know, it's probably under ten thousand in The U. S. And similarly in Europe.
But again, we're pretty early in the learning curve here so those numbers may be different but that's the way we're thinking about the market size there.
Speaker 8
Okay, awesome. That's very helpful. Thank you so much.
Speaker 2
Thanks Alex.
Speaker 0
The next question comes from Yale Jen with Laidlaw and Co. Please go ahead.
Speaker 6
Good afternoon and thanks for taking the questions. I just got two quick ones. The first one is that Metabrel recently reported their Phase three, one of the Phase three study and I know a number of analysts have commented on that. I'm just curious what's your thoughts in terms of that data readout? And then I have a follow-up.
Speaker 2
Yeah, thanks Yale. Yeah, think the data looked good there. It's an NAFLD study and the effect on liver fat was really impressive. And I think it supports the mechanism that further confirmatory data that activation of thyroid beta receptor is a, you know, really potent means of reducing liver fat content and plasma lipids. So we thought the data were positive.
Speaker 6
Okay, great. And the follow-up question is that we believe that the triazepatide may also have a Phase III readout sometime in second half of this year. Just curious what's your thoughts? If that readout is positive, what kind of sort of impact on the development of two thousand seven hundred thirty five? And thanks.
Speaker 2
Yeah, I think there will be obesity data later this year for tirzepatide. And the mechanism, at least in diabetics, has shown to be very potent at reducing body weight. So if you're looking at the overall obesity population with or without diabetes, it might be even more effective in the nondiabetic patients. That would be really exciting for us because we think the profile is dissimilar, maybe in some ways slightly better with VK2735 relative to tirzepatide, but the mechanism, very attractive and really potent there. And I think if they have positive data it bodes well for the potential efficacy of VK2735.
Speaker 6
Okay, great. Thanks and again congrats on the excitement.
Speaker 2
Thanks, Yale.
Speaker 0
The next question comes from Scott Henry from Roth Capital. Please go ahead.
Speaker 9
Thank you and good afternoon. Just a couple of questions. The first one is kind of a tough question, but I'm just curious your thoughts. With regards to data by year end for 2809, just want to get a sense of your confidence level. I mean, would you be surprised if it wasn't in there?
Or is that a stretch target? Just any kind of color you can give of how confident you are of that target.
Speaker 2
Well Scott we're as confident as we can be but having said that we've missed every estimate so far. So we're going to try and do the best we can, and that's where we think the models point right now. But, again, the pandemic has really thrown a wrench into all projections, that we've ever, you know, thought about. So we'll do the best we can and that's what we think right now.
Speaker 9
Okay. Fair enough. And then with regards to X ALD, assuming the you get the, genotoxicity study data in 2Q, should we be thinking about that data perhaps '3? Just trying to get a sense of how much time we should bake in for the turnaround of that in getting the trial back up and running.
Speaker 2
Yes. You mean the top line data from the study available in the '3? Yes. Well, the way we looked at that is really it's probably a six month delay in the study. So if we were previously expecting data by the end of the year 2022 probably imply the data 2023, mid-twenty twenty three, something like that.
Speaker 9
Okay, perfect. Thank you. And then with regards to, 2735, are you going to file an IND for that product? I assume the phase one is outside The US. Just trying to get a sense of that.
Speaker 2
Yes, that's right. We'll file an IND later this year or early next year. But, yes, the Phase I study is not, in The U. S. That's correct.
Speaker 9
Okay. And then I guess, kind of the final question on 2735. That Phase I data, how should we think about what we might learn as far as the obesity endpoint? Granted those are healthy subjects, so I would imagine we would expect to see a smaller difference. Just want to get your sense of how much insight we may learn from that early obesity data.
Speaker 2
Yeah. It's a fair question and a difficult question. You know, we would look for weight loss at the higher doses, but, you know, you're right. It is a healthy volunteer study. So it's a little more difficult to show an effect.
But when we look at, you know, diabetes, for example, and other indications, when you when you see weight loss, it it happens in both the, you know, so called normal to to heavier, patients. You just don't see it as much in the in the normals. So, it'll be an interesting dataset. Certainly, when we look at body weights at baseline, we'd want to pay attention to the ones that are a little heavier and see how they respond, relative to the ones that are leaner. But, again, hard extrapolate since they are healthies.
Speaker 9
Okay. And absolute final question, spending for 2022, any patterns to how we should think about R and D?
Speaker 3
Hey, This is Greg. Yes, I think we spent about $46,000,000 in 2021. About three quarters of that was direct costs essentially for our development programs or three development programs. Looking at 2022, think you could think about that increasing by about 25% to 30% on the cash usage standpoint. But we're funded well through major catalysts in all three programs at this point from an overall runway standpoint.
Speaker 9
Okay. And would you expect that to increase throughout the year or relatively consistent?
Speaker 3
I think pretty consistent throughout the year.
Speaker 9
Okay, great. Thank you for taking all the questions.
Speaker 2
Thanks Scott.

The next question comes from Thomas Smith with SVB Leerink. This
Speaker 10
is Mike Cracki on for Tom. Assuming you achieved statistical significance on the primary endpoint at three months in voyage, would you plan on waiting for the full twelve month histology results before moving to a Phase III study? And then as a follow-up to that, how quickly do you
Speaker 5
think you could initiate a pivotal Phase III?
Speaker 2
Hey, Mike. Good question. So the guidance as it exists now requires the histology data from, twelve months or whatever the endpoint is in your phase 2b study. So, we can start preparing, for phase three, and, we can hopefully determine the doses that we would, or, you know, get a little better focus on the doses that would likely proceed in phase three based on the twelve week data. But we won't be able to really, you know, file the final protocol and and really start the study, until I'd say a minimum six months after completion of the study.
Speaker 10
Got it. That's helpful. And then just separately, you've mentioned that MADRIL is going to have their pivotal data expected as early as the third quarter of this year. Do you anticipate to see some increased interest from potential partners ahead of that or on that in the event that they're successful?
Speaker 2
Sure. I'm not sure I mentioned that. But I understand their day will be later this year. And, yeah, if the study is successful, I think that there will be interest from multiple parties in both data sets, their data as well as our data. So yeah, would think so, yeah.
Speaker 10
Understood. Thanks for taking our questions.
Speaker 2
Thanks, Mike.

The next question comes from Justin Thielen with BTIG. Please go ahead.
Speaker 4
Hi, thanks for taking the question. Brian, wanted to follow-up on Yale's question earlier regarding the competitive landscape. So from my perspective, the safety profile of 2809 appears to be fairly clean. Just wanted to ask if you'd expect the safety to be pretty consistent in VOYAGE or whether potentially, you could see some higher events of GI adverse events given patients may also be on GLP-1s or other concomitant medications?
Speaker 2
Yeah, it's an interesting question. I don't know. I mean they are probably a little sicker and it is a gastrointestinal disease, you know, NASH. So maybe there's a little higher baseline. But we've not seen any GI impact, really either compound, in phase one or phase two with VK2809.
So, it's possible once you get into a larger study like this in a more diseased population, but there's no indication that that's, you know, likely to happen. Great. Thanks for taking the
Speaker 6
Justin.
