Hello, and welcome to the Viking Therapeutics 2021 Third Quarter Financial Results Conference Call. (Operator Instructions) As a reminder, this conference call is being recorded today, November 3, 2021. I'd now like to turn the conference over to Viking's Manager of Investor Relations, Stephanie Diaz. Please go ahead, Stephanie.
Stephanie Diaz
Hello, and thank you all for participating in today's call. Joining me today is Brian Lian, Viking's President and CEO; and Greg Zante, Viking's CFO. Before we begin, I'd like to caution that comments made during this conference call today, November 3, 2021, will contain forward-looking statements under the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995, including statements about Viking's expectations regarding its development activities, time lines and milestones. Forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially and adversely and reported results should not be considered as an indication of future performance. These forward-looking statements speak only as of today's date, and the company undertakes no obligation to revise or update any statement made today. I encourage you to review all of the company's filings with the Securities and Exchange Commission concerning these and other matters.
I'll now turn the call over to Brian Lian for his initial comments.
Brian Lian - President, CEO & Director
Thanks, Stephanie, and thanks to everyone dialed in by phone or listening on the webcast. Today, we'll review our third quarter 2021 financial results and provide an update on recent developments and progress with our pipeline programs and operations. During the third quarter, we continued to enroll patients in our Phase IIb VOYAGE trial, evaluating VK2809, our novel thyroid hormone beta receptor agonist for the treatment of NASH and fibrosis. We also made progress with our second thyroid hormone beta receptor agonist VK0214 for the treatment of X-linked adrenoleukodystrophy, or X-ALD. During the quarter, we continued enrollment in a Phase Ib clinical trial evaluating VK0214 in patients with X-ALD.
In addition, earlier this week, we presented 2 posters at Obesity Week, the Annual Meeting of the Obesity Society highlighting promising results from a new internally developed program targeting the GLP-1 and GIP receptors for metabolic disorders. These posters highlighted early results that show promising effects on body weight and metabolic profile in an in vivo model of obesity. I'll provide additional detail on our operations and development activities after we review our third quarter financial results. For that, I'll turn the call over to Greg Zante, Viking's CFO.
Gregory S. Zante - CFO
Thanks, 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 later today. I'll now go over our financial results for the third quarter and 9 months ended September 30, 2021, beginning with the results for the quarter. Our research and development expenses for the 3 months ended September 30, 2021, were $10.8 million compared to $7.1 million for the same period in 2020. The increase was primarily due to increased expenses related to manufacturing for the company's drug candidates, clinical and preclinical studies and services provided by third-party consultants, partially offset by decreased expenses related to salaries and benefits and stock-based compensation.
Our general and administrative expenses for the 3 months ended September 30, 2021, were $2.6 million compared to $2.7 million for the same period in 2020. The decrease was primarily due to decreased expenses related to salaries and benefits, partially offset by increased expenses related to stock-based compensation, insurance and legal services. For the 3 months ended September 30, 2021, Viking reported a net loss of $13.2 million or $0.17 per share compared to a net loss of $9.3 million or $0.13 per share in the corresponding period in 2020. The increase in net loss and net loss per share for the 3 months ended September 30, 2021, was primarily due to the increase in research and development expenses, partially offset by the decrease in general and administrative expenses noted previously as well as decreased interest income, primarily due to the decline in interest rates available throughout the third quarter of 2021 as compared to prevailing interest rates during the same period in 2020.
I'll now go over the results for the first 9 months. Our research and development expenses for the 9 months ended September 30, 2021, were $35.1 million compared to $22.9 million 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 9 months ended September 30, 2021, were $8 million compared to $8.5 million for the same period in 2020. The decrease was primarily due to decreased expenses related to salaries and benefits, stock-based compensation and legal services, partially offset by increased expenses related to insurance, professional fees and services provided by third-party consultants.
For the 9 months ended September 30, 2021, Viking reported a net loss of $42.6 million or $0.55 per share compared to a net loss of $28.5 million or $0.39 per share in the corresponding period of 2020. The increase in net loss and net loss per share for the 9 months ended September 30, 2021, was primarily due to the increase in research and development expenses, partially offset by the decrease in general and administrative expenses noted previously as well as decreased interest income primarily due to the decline in interest rates available throughout the 9 months ended September 30, 2021, as compared to prevailing interest rates during the same period in 2020.
Turning to the balance sheet. At September 30, 2021, Viking held cash, cash equivalents and short-term investments totaling $216.1 million, compared to $248.4 million as of December 31, 2020. This concludes my financial review, and I'll now turn the call back over to Brian.
Brian Lian - President, CEO & Director
Thanks, Greg. I'll now provide an update on progress with our development 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. In clinical studies, VK2809 has demonstrated the best-in-class profile for the potential treatment of metabolic and lipid disorders. A prior 12-week Phase IIa study evaluating VK2809 in patients with nonalcoholic fatty liver disease and hypercholesterolemia, successfully achieved both its primary and secondary end points. Patients receiving VK2809 at doses as low as 5 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. Follow-up data presented at the 2020 EASL conference showed that treatment with VK2809 resulted in durable reductions in liver fat with the majority of patients remaining responders 4 weeks after completion of the study. Importantly, no serious adverse events were reported in this trial among patients receiving VK2809 or placebo.
We believe that VK2809's exceptional low dose potency in reducing liver fat and plasma lipids, its durable effect and its safety and tolerability profile to date established it as a best-in-class compound for the potential treatment of patients with NASH and fibrosis. Notably, VK2809's lipid-lowering effects may lead to improved cardiovascular benefits in treated patients. This is a critical advantage in a field where multiple competitive mechanisms in development are associated with elevations in lipids that are known to increased cardiovascular risk.
Following the promising results observed in our 12-week Phase IIa study, we initiated a Phase IIb 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 5 treatment arms, and the target population includes patients with F2 and F3 fibrosis as well as up to 25% with F1 fibrosis.
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 12 in patients treated with VK2809 as compared to patients receiving placebo. Secondary objectives include the evaluation of histologic changes assessed by hepatic biopsy after 52 weeks of treatment.
Through the third quarter, enrollment and dosing in VOYAGE continued at sites in the U.S. and abroad. We continue to navigate a challenging clinical environment, and we expect to complete enrollment and announce top line data in 2022.
I'll now provide an update on our VK0214 program, which is our second orally available small molecule thyroid hormone receptor beta agonist. VK0214 is currently in development for the treatment of X-linked adrenoleukodystrophy, or X-ALD. X-ALD is a rare and often failed metabolic disorder characterized by a breakdown in the protective barriers 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 these 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.
What makes VK0214 a promising potential therapeutic in this setting, stems from the key regulatory role played by the thyroid hormone beta receptor on the expression of an alternative very long chain fatty acid transporter known as ABCD2. Various preclinical models have demonstrated that increased expression of ABCD2 can lead to improved and potentially normalized very long chain fatty acid metabolism. For this reason, we believe that VK0214's potent activation of the thyroid hormone beta receptor may represent a potential therapeutic approach to the treatment of X-ALD.
Last year, we initiated a randomized, double-blind, placebo-controlled, single ascending and multiple ascending dose Phase I 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 14 days. This study successfully achieved its primary objective, with VK0214 shown to be safe and well tolerated at all doses evaluated. No serious adverse events were reported, and no treatment or dose-related trends were observed for gastrointestinal side effects, vital signs or cardiovascular measures.
Treatment with VK0214 demonstrated dose-dependent exposures, no evidence of accumulation and the half-life consistent with anticipated once-daily oral dosing. A secondary objective of the study was to evaluate laboratory assessments, including a lipid panel to determine potential pharmacodynamic effects following exposure to VK0214. The results showed that subjects who received VK0214 experienced reductions in LDL cholesterol, triglycerides, apolipoprotein B and lipoprotein A following 14 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.
Given these positive results, earlier this year, we initiated the Phase Ib study of VK0214 in patients with the adrenomyeloneuropathy or AMN form of X-ALD. AMN is the most common form of X-ALD affecting approximately 50% of those with the disease. Clinical manifestations include progressive leg weakness, incontinence and sexual dysfunction. Our Phase Ib study is a multicenter, randomized, double-blind, placebo-controlled trial in adult male patients with AMN. The study is initially targeting enrollment across 3 cohorts: placebo, VK0214 dosed at 20 milligrams daily and VK0214 dose at 40 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 28-day dosing period. In addition, the study will assess the efficacy of VK0214 at lowering plasma levels of very long chain fatty acids and evaluate the pharmacokinetics of VK0214 in this population. Enrollment in this study is ongoing, and we currently expect top line results to be available in 2022.
In addition to our ongoing clinical trials targeting NASH with VK2809 and X-ALD with VK0214, we have been working hard to expand our pipeline of novel best-in-class therapeutics targeting areas of unmet need in metabolic and endocrine disorders. To this end, earlier this week, we reported the first data from an internally developed program targeting novel dual agonists of the glucagon-like peptide 1 or GLP-1 and the glucose-dependent insulinotropic peptide or GIP receptors. Agonists of the GLP-1 receptor have demonstrated consistent benefits in diseases such as type 2 diabetes by improving insulin sensitivity, reducing plasma glucose and reducing overall body weight. As a result of these therapeutic effects, multiple GLP-1 receptor agonists have been approved for both diabetes and obesity.
More recently, the focus in this area has turned to the development of therapies that can maintain post activation of the GLP-1 receptor while also activating other important receptors related to metabolic control. One of these approaches has been to simultaneously target the GIP receptor to provide enhanced stimulation of insulin secretion, thereby improving overall glucose control.
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-1 and GIP receptors may therefore provide improved metabolic benefit relative to activation of either single receptor alone. Indeed, recent clinical data have demonstrated that dual GLP-1, GIP agonists not only provide excellent glucose control, but also potent reductions in body weight.
In 2019, we initiated an exploratory program targeting novel dual agonists of the GLP-1 and GIP receptors. This program has evolved nicely and we have been pleased with our progress and portfolio to date. We are excited to now be in the position to share some of the early data generated by this program.
Earlier this week, we presented 2 posters at Obesity Week, the Annual Meeting of the Obesity Society highlighting certain preclinical studies conducted in an in vivo model of obesity. The results of these studies demonstrate that in this model, the addition of GIP receptor activity improves upon the observed effects resulting from activation of the GLP-1 receptor alone. Weight loss, glucose and insulin effects were enhanced in the Viking series of dual agonist compared with the effects observed with the GLP-1 agonist comparator semaglutide when administered at the same dose for the same length of time.
In separate studies, the effect sizes observed with the Viking series of dual agonists were similar to those observed following treatment with tirzepatide, a dual GLP-1 GIP receptor agonist currently in clinical development. Reductions in liver fat content were generally numerically larger among animals treated with the Viking compounds relative to the liver fat reductions observed among tirzepatide-treated animals. Highlights from the poster presentations include results showing that treatment with our novel dual agonist for 21 days, resulted in statistically significant mean reductions in body weight of up to 27% relative to vehicle treatment.
In addition, treatment with our dual agonist resulted in statistically significant mean reductions in blood glucose of up to 23% and plasma insulin reductions of up to 57% relative to vehicle treatment. In a separate 14-day study, treatment with our novel dual agonist resulted in statistically significant mean reductions in plasma triglycerides of up to 37% relative to vehicle. In this study, treatment with our compounds also resulted in statistically significant mean reduction liver triglycerides of up to 49% relative to vehicle treatment.
In general, data from these studies demonstrated statistically significant improvements on these measured compared with a control cohort that received treatment with semaglutide. Results were also comparable to those observed among the control cohort of animals treated with the development stage dual agonist tirzepatide. We are highly encouraged by these early results and look forward to presenting additional data from this program at future scientific meetings.
Based on the results from these and other preclinical studies, we plan to initiate clinical studies with a lead compound from this program in the coming months. We are excited to be advancing this new program, and we will provide additional information on the trial design and other details at the appropriate time. As we advance our clinical programs and expand our therapeutic pipeline, we're also keenly focused on the prudent management of our balance sheet. As Greg noted earlier, we ended the third quarter with approximately $216 million 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.
In conclusion, we remain focused on the development of first-in-class and/or best-in-class therapeutics for the treatment of metabolic and endocrine disorders. We believe our clinical track record establishes the company as a leader in the field, and we continue to advance our existing clinical programs as well as explore new opportunities to create value for patients, clinicians and investors. Our lead program evaluating VK2809 for the treatment of NASH and fibrosis is progressing through the Phase IIb VOYAGE study, and we expect to complete enrollment and report initial data from this study in 2022.
Our second clinical candidate VK0214 for the treatment of X-ALD is in an ongoing Phase Ib study in patients with adrenomyeloneuropathy, and we expect to complete this study in 2022. Finally, as a result of our internal efforts to expand our pipeline, earlier this week, we announced the initial results from a series of novel dual agonists of the GLP-1 and GIP receptors, which have shown promise in preclinical models. We expect to initiate clinical development of a lead compound from this series in the coming months. This concludes our prepared comments for today. Thanks again for joining us, and we'll now open the call for questions. Operator?

(Operator Instructions) And today's first question comes from Joon Lee with Truist Securities.
Joon So Lee - VP
The first question is, are you able to disclose where you are in the enrollment of VOYAGE? And do you expect the data in the first half or second half of '22? And I have a follow-up.
Brian Lian - President, CEO & Director
Joon, thanks for the question. We aren't in a position to really disclose the enrollment numbers, but -- and I think that's consistent with we've done in the past. Right now, I would say, middle of the year would be probably on the early edge of when we would have the initial data available.
Joon So Lee - VP
Got it. And regarding your dual agonist, Just really curious if that 27% weight loss you saw in mice could be translated into maybe 10% or greater weight loss in human. I'm asking because that seems to be the bar set by another dual agonist that reported recently.
Brian Lian - President, CEO & Director
Yes. It's always hard to extrapolate, but we had tirzepatide in the studies, the second poster anyway as a control. And we seem to be essentially right in line with the tirzepatide efficacy level, which I think generally is in that 10% to 12% range, maybe a little larger depending on the population. But I think it's -- again, this is mice, but it looks competitive at this point.
Joon So Lee - VP
Right. Just -- actually, the drug I was referring to is ALT-801 from Altimmune, there is this oral. I mean, how important is that, that drugs like these are oral versus subcu? Any read-throughs from experience from the oral versus subcu semaglutide?
Brian Lian - President, CEO & Director
Sure. I think orals generally would be preferred by patients, especially as you get a little older. But given the efficacy and the therapeutic benefits, it's hard to say. If you have something that's maybe dosed less frequently that might be preferable. But really, if you look at the size of this -- the markets that this mechanism could apply in. And I think you'll see multiple modalities and multiple different compounds really being able to be successful.
Operator
And the next question comes from Matt Luchini with BMO Capital.
Matthew W. Luchini - Analyst
First, I guess, on VOYAGE again, just thinking about your expectations for where we were versus last quarter, if there's anything different in your thinking? In other words, is patient recruitment environment at this point, better, worse or in line with your expectations? And then on the dual agonist, just would like to get some thoughts on how you're thinking about indication selection here. Obviously, I'm not afraid of big -- of markets with big development programs. But as you look at the therapeutic and competitive lens, where do you think a product like this could have the greatest impact?
Brian Lian - President, CEO & Director
Yes. Thanks, Matt. With the VOYAGE enrollment, I think it's been continually challenging. It's been pretty steady since the summer, and we've continued to expect an uptick enrollment as the COVID pandemic sort of winds down, at least in the U.S., and we haven't really seen that. We think there are a lot of unexpected challenges with COVID. I think there are staff shortages at sites, staff shortages at CROs. We have also surprisingly the impact of COVID studies on on site operations has been larger than I think we would have ever expected. But it's been consistent. I mean we've been enrolling steadily, and it's not as fast as we'd like or anybody would like, but it's moving forward.
With the profile of the dual agonist, I think what generally, you see with the dual agonist is efficacy that looks to be a little bit better than the single GLP-1 agonist even if you dose up with the GLP-1 agonist. So I think the therapeutic profile will be really attractive if any of these are ultimately approved. And that would hold really in any indication in obesity or diabetes or NASH.
Matthew W. Luchini - Analyst
Okay. I guess -- well, okay. And I guess maybe last question then would be, it looks like spending is down pretty decently sequentially. Just wondering, in the past, there's been a talk about 50% or 70% step-up in OpEx this year. That obviously implies a hefty lift in the fourth quarter. Just wondering how we should be thinking about that going into year-end?
Gregory S. Zante - CFO
Matt, I think the spend and expenses for the fourth quarter will be pretty similar to what we've seen here in the third quarter. So I think our pickup, we might see a bit into next year. But for now, I'd say for the upcoming quarter, you could think of it similar to the third quarter.
Operator
And the next question comes from Steve Seedhouse with Raymond James.
Steven James Seedhouse - Research Analyst
It seems as the FDA -- just with respect to NASH and what the FDA is looking for from histology assessment protocol. There seems to be some clarity coming there. These 3 pathologists panels are being used now by Intercept and others. I'm just curious if this is something that you've heard from the FDA directly if it's something that you plan on incorporating into Phase II? Or is this only a relevant protocol to consider as you think about a Phase III study?
Brian Lian - President, CEO & Director
Thanks, Steve. Yes, I think it's probably more applicable to Phase III than Phase II. We are using multiple pathologists reads in cases where we have close calls. I mean, sometimes, if someone's got clear NASH and ballooning and steatosis and inflammation and fibrosis. I mean, there's no need for a second opinion there. But in the closed calls, it's very helpful, and we're doing that. And I think moving into Phase III, we and everybody else would probably skew toward that multi reader approach because it just reduces the variability. And at least you have to get the consensus as well.
Steven James Seedhouse - Research Analyst
Okay. And just the only other question I had is as you think about this dual agonist and the NICE data that you presented preclinically and your plans to move this into the clinic in the coming months. Would it be safe to say that this sort of takes priority is the next pipeline asset over like the DGAT-1 inhibitor and you have PPAs inhibitor and other things in your pipeline?
Brian Lian - President, CEO & Director
Yes, that's a great question. Yes. Yes. I think right now it is. The data were probably a little better than we expected. And so we prioritized it, and we're moving toward the clinic as quickly as we can. But that doesn't mean the other programs are unimportant. This is just bumped ahead of them based on what we've seen so far.
Operator
And the next question comes from Jay Olson with Oppenheimer.
Jay Olson - Executive Director & Senior Analyst
For -- sorry, VK2809, are there any competitor dynamics that you're looking out for in the near term that you think could provide important read across? And then I had a question on your GLP-1, GIP as a follow-up.
Brian Lian - President, CEO & Director
Yes, sure. I think the big data set for the thyroid beta mechanism is expected sometime in the second half of next year. So that's what we would certainly be looking for. And I think most people will be looking for that as validation of the mechanism and a way to gauge the impact on fibrosis and NASH resolution in a larger population. So I think everybody is interested in that data set next year.
Jay Olson - Executive Director & Senior Analyst
Okay. Great. And then I think you said that you were looking forward to initiating clinical development for your GLP-1, GIP program. Does that mean that you have nominated a candidate? And can you just talk about the IND filing time line?
Brian Lian - President, CEO & Director
Yes, it does mean we've nominated the candidate. We're not in a position right now to identify it, but we do have a candidate in mind. And we said we'd start the study hopefully in the next few months. So I don't want to give any timing on an IND filing or anything like that. But that -- I think guidance within the next few months is safe to say for initiation of a study.
Jay Olson - Executive Director & Senior Analyst
And congrats on the progress.
Brian Lian - President, CEO & Director
Thanks a lot, Jay.

And the next question comes from Andy Hsieh with William Blair.
Tsan-Yu Hsieh - Senior Research Analyst
Congratulations on really extending your pipeline. So maybe a high-level question, Brian. Maybe highlight your R&D capability. This is something that we just haven't heard a lot about maybe hit to lead optimization, screening regarding basis plays or something like that. Just kind of educate us on where you are in terms of your R&D infrastructure.
Brian Lian - President, CEO & Director
Thanks, Andy. It's a good question. So just to reiterate, the vast majority of our efforts are on the clinical side with VK2809 and VK0214, but we do spend a fair amount of time in the literature and watching the competitive landscape. And the company has always been sort of modeled on this virtual outsourcing approach. So when we find an interesting target or an interesting area to look at, we contact the appropriate vendors and get really targeted on the specific studies that would be the most useful for us in order to avoid a huge incremental uptick in spend. and it seems to work. We've dabbled in a lot of areas. Not everything seems to stick, but this one seemed to look pretty nice. And the more we learned about it, it seemed to rise to the top of some of the other things we've been looking at. So that's why we've decided to put a little more effort into this. But it really is compound and project-specific regarding how we approach the development path.
Tsan-Yu Hsieh - Senior Research Analyst
That's very helpful. And just, again, probably a longer-term question. Just regarding the strategy here. Obviously, if you look at the tirzepatide program, 5 large facing programs. So maybe kind of provide us with your longer-term vision? Are you going to combined with 2809 in NASH, just have basically an in-house combinatorial optionality and then partner out the larger ones to big pharma, that kind of stuff.
Brian Lian - President, CEO & Director
Yes. Yes. That's a good question. So I think this fits within the way we've always thought about VK2809 as well, and that is these big markets are probably best addressed with a partner. And so whether that's before Phase III or after Phase III, these large markets that require large infrastructure would -- first choice would always be to partner. And we've always been open to partnering discussions. Where these programs could work internally most feasibly is on the orphan side. So we think for rare diseases, we could launch and commercialize a product there without a massive uptick in infrastructure. But the GLP GIP program would fit more along the lines of the way we think about our VK2809 asset, we're partner to be preferred for the much larger expensive programs, our clinical development programs.
Operator
And the next question comes from Yale Jen with Laidlaw & Company.
I-Eh Jen - MD of Healthcare Research & Senior Biotechnology Analyst
I just want to confirm in terms of the 0214 in terms of the potential sort of data readout from the Phase Ib, would that be in the second half of this year or next year or that could be pushed out to '23?
Brian Lian - President, CEO & Director
Thanks, Yale. No, we would hope to have it next year, probably be in the second half of next year, but that the plan is to hopefully have the top line available by the end of the year in 2022.
I-Eh Jen - MD of Healthcare Research & Senior Biotechnology Analyst
Okay. Great. And one more question in terms of the dual agonist, as you indicated that the study will start in a couple of months, is that referring that or suggesting that the GLP talks or the study has been done or is still ongoing?
Brian Lian - President, CEO & Director
That's a great question, Neil. And I don't want to get into that level of detail. But obviously, we have to do some talks before we go into humans. And so it would be reasonable to assume that, that's underway or enough has been completed to allow us to consider moving into humans. But good question. We're just not going to give that level of detail right now.
Operator
And the next question comes from Justin Zelin with BTIG.
Justin Reid Zelin - Biotechnology Research Analyst
Congrats on the progress this quarter. So first, on the dual agonist, I was just curious on the PK/PD front, whether we should expect the frequency of administration of the drug to be comparable to tirzepatide? Or do you think there's potential to potentially push the duration back to more than a once-weekly dose?
Brian Lian - President, CEO & Director
Yes. This is -- it's a good question. We'll have more insight on that after we get some human data. But I would say it's not a daily. It would be a longer-acting agent. But just how long that is, we really won't have a good handle until we start looking at some of the human data.
Justin Reid Zelin - Biotechnology Research Analyst
Great. Okay. That makes a lot of sense to me. And you mentioned that you're also looking at the competitive landscape and are scouting new mechanisms. Is there anything of interest at the upcoming liver meeting that particularly stands out to you?
Brian Lian - President, CEO & Director
Not with regard to new mechanisms we're looking at, but I think the semaglutide data will be interesting. The FGF21 data will be interesting. So those would be the areas we'd probably be most focused on with respect to the AASLD meeting.
Justin Reid Zelin - Biotechnology Research Analyst
Great. Well, congrats again on the progress.
Brian Lian - President, CEO & Director
Thanks a lot, Justin.
Operator
And the next question comes from Thomas Smith with SVB Leerink.
Michael Holden Kratky - Research Analyst
This is Mike on for Tom. With respect to the dual-acting program, how are you thinking about the potential antifibrotic benefit for the mechanism? And then separately, do you have an initial sense of what that early study design could look like, and if we might be getting some type of efficacy results?
Brian Lian - President, CEO & Director
Yes. Good question, Mike. So what we've seen with the studies of semaglutide is that you see a really terrific effect on NASH resolution. And what looked to be trends in fibrosis improvement that might become clear with longer exposure. So all of the arrows sort of point the right direction on fibrosis, but the effect seems to be at least early most pronounced on NASH resolution. With respect to Phase I study, I think the template would probably look like the SAD/MAD study that we did with VK0214. So you're able to parallel track both of those. And you could probably look at some early pharmacodynamic signals from that sort of a study.
Operator
Thank you. And this concludes the question-and-answer session. I now would like to turn the call to Stephanie Diaz for your closing comments.
Stephanie Diaz
Thank you again for your participation and continued support of Viking Therapeutics. We look forward to updating you again in the coming months. Have a great afternoon.
