Thank you, Richard, and good morning, everyone. We appreciate you joining us today for a discussion of our first-quarter 2022 financial results and business update. We continue to advance multiple clinical trials for our lead product candidate, pemvidutide, a GLP-1 glucagon dual receptor agonist and are excited about reporting important data from these trials in the second half of 2022. Last month, we announced the initiation of the 48-week Phase 2 MOMENTUM trial of pemvidutide in subjects with obesity or who were overweight. That trial is ongoing at multiple sites in the United States with Dr. [Indiscernible], professor of clinical medicine at Weill Cornell Medical School, and a leading authority in obesity and obesity clinical trials, serving as the principal investigator. Dosing has commenced and a planned interim analysis to assess changes in body weight after 24 weeks of treatment is expected to readout in the fourth quarter of 2022. Enrollment in the Phase 1b non-alcoholic fatty liver disease or NAFLD trial has been completed, and data readouts for weight loss and liver fat reduction at 12 weeks of treatment are expected in the third quarter of 2022. In addition, a double-blind placebo-controlled 12-week extension of the NAFLD trials has been initiated with an expected data readout on weight loss at 24 weeks in the 4th quarter of 2022. We believe that the 24-week weight loss readout from the NAFLD extension trial will provide a valuable read through to the Phase 2 momentum obesity trial. A 12-week trial to characterize effects of pemvidutide on glucose control in diabetic subjects with overweight and obesity is also ongoing. This trial will further expand on the findings from our Phase 1 trial, in which decreased insulin resistance and maintenance of glucose control were observed in an obese and overweight patient population that included…

Thank you, Vipin, and good morning, everyone. First, let me talk about the Phase 2 two MOMENTUM trial of pemvidutide in obesity. We expect this trial will enroll approximately 320 non-diabetic subjects with either obesity or overweight, with at least one obesity related complication. Subjects will be randomized one-to-one to one-to-one to receive either 1.2 milligrams, 1.8 milligrams, 2.4 milligrams pemvidutide or placebo, administered weekly for 48 weeks. The primary endpoint of the MOMENTUM trial is the relative percent change in body weight at 48 weeks compared to baseline with additional readouts, including metabolic and lipid profiles, cardiovascular measures and glucose homeostasis. Dr. Louis Aronne from Weill Cornell Medical College, a leading authority in obesity and obesity clinical trials, is serving as the principal investigator. An interim analysis is planned to assess changes in body weight after 24 weeks of treatment with an expected readout in the fourth quarter of 2022, and a 48-week readout in the middle of 2023. As Vipin mentioned, we completed enrollment in our Phase 1b NAFLD clinical trial of pemvidutide and expect a data readout in the third quarter of 2022. This trial is designed to assess the effects of pemvidutide on liver fat, and body weight in subjects with obesity or overweight with NAFLD, defined as a 10% or greater liver fat content as measured by MRI-PDFF. Non-diabetic and diabetic subjects were randomized 1 to 1 to 1 to 1 to pemvidutide 1.2 milligrams, 1.8 milligrams, 2.4 milligrams or placebo over 12 weeks of treatment. The primary endpoint of this trial is the reduction in liver fat by MRI-PDFF. But a key secondary endpoint is weight loss at the end of 12 weeks of treatment as we believe that obesity is the key driver of NAFLD and NASH. Based on the results of our…

Thank you, Scott. And good morning again everyone. For today's call, I'll be providing a brief update on Altimmune's first quarter 2022 financial and operating results. More comprehensive information will be available in our Form 10-K to be filed with the SEC later today. I also will provide some guidance on our expenses for 2022. Altimmune ended the first quarter of 2022 with approximately $180 million cash and cash equivalents compared to $190.3 million at the end of 2021. Turning to the income statement, revenue was minimal in the first quarter of 2022 compared to $800,000 in the same period in 2021. Our change in revenue for the quarter was primarily due to discontinuation of development activities for our T-COVID and [Indiscernible] programs, and it will be deminimis going forward. Research and development expenses were $15.1 million in the first quarter of 2022 compared to $11.9 million in the same period in 2021. The expenses for the quarter ended March 31, 2022, included $10.8 million in direct costs related to the development activities for pemvidutide and $2.5 million in direct costs related to development activities for HepTcell. As a reminder, we will owe one last development milestone of $3 million payable in common shares of the company within 60 days following dosing of the first patient in the Phase 2 trial pemvidutide, which occurred in April subsequent to quarter-end and will be reflected in the Q2 balance sheet. General and administrative expenses were $4.4 million in the first quarter of 2022 as compared to $3.8 million in the same period in 2021. The year-over-year change was primarily attributable to increased stock compensation expense. Net loss for the three months ended March 31, 2022 was $19.4 million or $0.44 net loss per share compared to $14.9 million or $0.38 net loss per share for the first quarter of 2021. We currently estimate that our research and development expenses for full-year 2022, including the $15.1 million reported in Q1 will be approximately $75 million. G&A expenses for the full-year 2022 are anticipated to be approximately $19 million. Approximately $8.5 million of these operating costs are for non-cash expenses, including stock compensation and depreciation and amortization. With the added financial flexibility afforded to the delay in initiation of a Phase 2 trial pemvidutide in NASH, our existing cash not only fully funds us through NAFLD and 48-week momentum obesity trial datasets, but we currently estimate that our cash is sufficient to allow us to operate well into 2024. I will now turn it back over to Vipin for his closing remarks. Vipin?

Thank you, Richard. Operator, that concludes our formal remarks. And we would like to open the line to take questions. Would you please instruct the audience on the Q&A procedure?

Thank you sir. [Operator Instructions] Thank you. Our first question will come from Seamus Fernandez with Guggenheim Partners.

Thanks, guys and congrats on the quarter. Obviously, good management and execution around the expenses. Can you help us understand a little bit, obviously, it's great to see the NASH study really more incorporated into potential strategic options going forward, but maybe you could just give us a little bit of clarity along those lines. How far into 2024 do you think the cash would likely take us? Just wanted to get a sense of that payment that you mentioned, Richard. Just wanted to get a little bit of clarification on the number that you mentioned there that's going to be paid, I think in the second quarter. I missed the absolute number I couldn't hear if it was 16 or 60, to be honest. And then the second question is really for Scott Harris, can you just help us understand what exactly you're looking to understand from these other Phase 1 studies in the context of the diabetic patient population and why the company's conducting those. I think those are some important questions. And then just my final question, Vipin, as you think strategically about the market opportunity here, obviously, you've mentioned the competitive landscape. But in the context of the size of this market opportunity, can you just help us better understand what you think the level of strategic interest is likely to be, and when that becomes a key discussion point for the company based on the data that you're bringing forward. Thanks.

Well, thank you, Seamus. Lots of questions there. We'll try to address them one-by-one. Let me just set the stage in terms of our rationale behind the NASH delay and the NASH study, the 52-week biopsy driven study. As you know, we've got a number of studies going on that will be generating significant amount of data in terms of liver fat reduction and we think that's going to be sufficient to drive the value proposition for people to draw the line. And we'll also be getting data from other companies, other players in NASH space during 2022. So we've put all that together, we think we'll have enough information to convince a strategic partner of the value proposition that we bring to NASH, which we think will be substantial. So given that, what we want to do is focus on obesity, generate as much data as we can and maintain financial flexibility. And truly driven by that, that we've decided to essentially postpone at this point initiation of a Phase 2 NASH study, which as you know are very long, so you're not going to see anything out of that study until sometime in 2024, even if we start that study right now. So it was given all of those considerations we felt we would still be able to retain the upside value of the NASH indication in our discussions. And I'm pretty sure that its strategic partner would want to pursue both the obesity and NASH indications just like other large pharma players are doing in this -- in the [Indiscernible] space. So there's no question that [Indiscernible] will play a role in NASH treatment ultimately. It's just a matter of timing. So that's the rationale that we're using. With that, let me just turn it over to Richard to talk about the -- your questions about the funding and financing, and how long will that last. Richard.

Sure. Thanks Vipin. Thanks for the questions, Seamus. We didn't provide specific guidance on to how deep into 2024 we'll get; we believe it will be sufficient. We should have, give or take, approximately a year's cash when we have the data or completion of the MOMENTUM trial. So I hope that helps of course, a lot of changes as time goes on, depending on what the data looks like and additional studies that you may or may not need to do. But it is sufficient to gather all the data, get to the FDA and have discussions and then we believe engaged in these potential strategic discussions. Regarding the payout for Spitfire, the amount is $3 million, I'm sorry for the confusion on that. It gets paid within 60 days following the achievement on the milestone. And it will be paid in shares, Seamus, there's a preset formula and the formula indicates that it will likely result in the issuance of approximately 850,000 common shares of the company.

Perfect. That's super helpful. And then just a last question on the diabetes patients and maybe just an update. If you guys are willing to provide us general color on how the momentum study is recruiting so far and how you're feeling in terms of that tracking to providing an interim look, whether it'd be at the full patient population or part of the patient population in the fourth quarter. Thanks.

Scott, do you want to take the diabetes first?

Sure. Thank you Seamus, for the question. I'll take the diabetes part first and then I'll finish with some comments about MOMENTUM study. So as you know, within the obesity population, 80% of that population does not have diabetes. And you're well aware that what really controls [Indiscernible] chronically in this population is the weight loss that was shown in the step trials. The change in hemoglobin A1C at 52 weeks is predominantly driven by the weight loss. So over the long run, we think that this drug will have excellent applications in diabetics. Also in our Phase 1 study, we saw no perturbations in glucose control measure by fasting blood sugar hemoglobin A1C. And in fact, as you would have expected with the weight loss that was observed, we actually had a reduction of insulin resistance that bodes quite well for the results of what we're going to see in 52 weeks, either in a non-diabetic population or a diabetic population. I think that we felt the obligation at this point to study the effects of pemvidutide acutely on aspects of glucose control that are typically studied in more intense Phase 1 studies such as continuing glucose monitoring and the like. And we really couldn't do that in our current studies, without making them too complicated. So we elected to conduct a committed study in diabetics and that's what we're trying to get out of the study right now.

I'll answer the second question about the momentum study, and I'm happy to go back and backfill on that answer I just gave you on the obesity. So the MOMENTUM study is going quite well. We're very enthusiastic with enrollment. We think it's going to enroll very, very quickly, like most obesity studies do. And we have 25 extremely enthusiastic investigators. The best guidance I can give you is we'll give you an update when the enrollment in the study completes and tell you what our plan's right now. Right now, we're optimistic that we'll have a very meaningful readout at the end of the year.

And Seamus -

Thanks, guys. Appreciate it.

And to your question about strategic thinking and the process going forward, look, the whole obesity space is maturing. I think the latest data from [Indiscernible] is helping. It's growing awareness. There'll be a lot of interest from multiple players in this space. That's how we see it. And what we are trying to do is really generate important data that will put us in the best position to do a robust transaction -- partnering transaction around this asset. So a lot of the studies, we've said it many times, we're doing these studies because we think they would add value in our strategic partnering discussions. I think overall, there are multiple players out there that are going to want to play in this space and we just want to be ready for that.

Excellent, thanks so much. Appreciate it.

Thank you. Our next question will come from Yasmeen Rahimi with Piper Sandler Companies.

Good morning, team. And thank you for taking my questions. I'm going to go one-by-one. Maybe a good place to start off would be, can you comment on the 1b NAFLD study what you're seeing in regards to discontinuation rates, how many data safety monitoring committees have you had? And what your expectations on in terms of GI tolerability? Anything safety-related to the 1b that you've been previewed to during this time could be helpful for us. And then I have few more.

Thanks for the question, Yasmeen. As you know, we continue to be blinded in the study and I can't give you data that we don't have. I will tell you that from the safety point of view, we're extremely pleased as we've said before with the safety profile and tolerability of the compound in that study as well as the other studies that we're conducting right now. There is no official data monitoring committee for the Study, you wouldn't expect it with a Phase 1 study. However, we have a safety committee that reviews the data from the study in a blinded fashion on a regular basis and those meetings have not identified any issues to-date consistent with what I've said before. Regarding the GI tolerability, we think it's only going to improve going forward. Remember that with Phase 1 studies, the tolerability profile of the compound is less optimistic than it would be in Phase 2 and Phase 3. And the reason is number one, there's less known about the compound at that time, there's more heightened, there's more concern about anything that you see. Investigators are heavily attuned to asking patients questions repeatedly.

Subjects are admitted to the unit for much of the time, so they are under constant surveillance. And then they come back weekly. That's very different from a Phase 2 environment like the MOMENTUM study when patients will be coming back, say, every two to four weeks and not being well monitored constantly. And was well shown in the tirzepatide and semaglutide programs, that when they went from Phase 1 to Phase 2, that they had a tremendous [Indiscernible] in their adverse events. So we were very happy with the tolerability profile that we had with pemvidutide in our Phase 1 program, we had no adverse event discontinuations. We think it's only going to get better going forward.

Thanks, Scott. I just wanted to clarify on the commentary, you made. One; Do you get notified when a discontinuation occurs and then hope study or the MOMENTUM study, and have you been notified?

Yes. I mean, we are notified, I am not free to speak on this on a specific basis other than to say that we're very happy with what we're seeing right now.

Got it. And then when you made the remarks that safety to GI tolerability could be looking more favorable in our Phase 2 study, are you saying that the Phase 1b NAFLD study GI profile could be given the protocols more similar to that 1b obese dataset that we have seen, or the execution of the 1b more like the Phase 2 momentum. Could you clarify, please?

I think that clearly as we go from Phase 1 to Phase 3, the tolerability profile of the compound improves, so one would expect based on that, that the tolerability in to Phase 2 might even be better than a 1b. But once you get the patients out of the Phase 1 unit and you know more about the compound and you have more confidence of the investigators with what you've seen, it gets better. So we expect that the tolerability in the Phase 1b study will be better than it was in the first-in-human study, and that will progressively get better going forward.

Thank you. And then last question. Any more commentary on what exactly we should be expecting out of the interim? What goes into your decision to decide whether you're going to pick 20 patients per arm or 30 patients for arm? Now it's been about a month-and-a-half, two months into the study, can you help us narrow down what exactly -- how big the interim analysis will include? And thank you for taking my questions.

Happy to answer that for you, Yasmeen. As you know, we're right now in the beginning of May. We still have a long way to go with a very rapid recruitment. We simply going to have to look at the data at the time that we have to do the cut-off and make that decision about whether it's a complete set or if it's an incomplete set? How many patients are in it? Based on our current projections, we think that the amount of subjects included in the interim analysis, if not the complete set, will be meaningful enough to be convincing of the data that's being seen. That's the best guidance I can give you until we see how enrollment is going.

And when do you make that decision? When is that time period? Is this in July then or at what time?

Yeah. Probably in that time frame, the middle of the year.

Okay. Great. Thank you.

You're welcome.

Thank you. Our next question will come from Liisa Bayko with Evercore ISI.

Hi there, how are you?

Good morning, Liisa.

Can you hear me? Good morning.

Yeah.

Before -- I wanted to ask quickly, for the study you're doing that does not include diabetics, the obesity study, are you just -- are you not in a point where you can include diabetics now? I know you have an earlier study, I'm just curious why not to take it all comers in a way.

Thanks for the question, Liisa. Well, typically in obesity studies, Liisa, if you look at the STEP program, the SURPASS program, the SURMOUNT program, in these Phase 2 obesity studies and Phase 3, diabetics and non-diabetics are not included. And I believe that the agency would want it that way as well. So consequently, you have to choose one or the other and we think that the more meaningful readout is going to be in the non-diabetics. Obviously at some point we do an obesity chronic study, but that Phase 2 study right now is in non-diabetics. And we think that taking the lead, given the precedent with STEP 1 and also SURMOUNT 1 which are non-diabetics, it just makes sense that we matched up by doing non - diabetics in MOMENTUM.

Yeah, the recent tirzepatide data was all non-diabetic.

Exactly.

So that's pretty standard in the obesity space to sort of co-mingle them in large studies.

Do you see the tirzepatide data is kind of your new benchmark in a way?

Yes. So we've been obviously looking at the whole landscape in obesity and I think first of all, let me say that it's really validating that the dual agonism approach is becoming more validated now. We clearly we can see benefit over just pure GLP-1 approach. So sort of the first benchmark was 15% to 20%, of that 15% range, we just have crossed the 20% mark. So tirzepatide, as you know, has about 20% to 22% weight loss. And that's great because I think the interest in multi agonism is going to grow with this. So we now know what GLP-1 and GIP can do. The question is, what can glucagon combined with GLP-1 do? Obviously we have some data at this point. And just to put things in perspective, tirzepatide showed about 20% to 22% after 72 weeks. We have shown 10% weight loss after just 12 weeks, 1/6 the time of just the tirzepatide data. So we feel very comfortable that we will be able to at least meet, perhaps, surpass that number as we go towards 48 weeks. So we're not only, we expect to be greater than tirzepatide, but also much faster in terms of getting there. In our 48-week study, we could already be approaching those numbers, so we feel very good about our prospects based on our Phase 1 data. Scott, you want to add something?

Yeah Liisa, I'll add to Vipin's comments that we're extremely excited by the prospect to delivering these results. Without dose titration we think this is a very, very important commercial advantage, both for patient satisfaction, patients who want to lose weight faster while they're paying for the drug in the first five months of therapy with tirzepatide and dose titration. And also the ease that it gives physicians for prescribing who really do not want to be involved in managing complex dose titration. It's well -- one of the thing I would point out is that our lipid profile appears to be superior to that of both tirzepatide and semaglutide. So you get the weight loss, it's certainly very important and it's very pleasing to people and doctors. But what you really want to do is decrease the comorbidities, and you achieved that by -- in many ways by reducing the lipids. The meaningful aspects of weight loss have to be translated into lipids to reduce the cardiovascular risk and we think we have a superior profile based on the inclusion of glucagon over the monotherapy or the dual therapy that includes GIP but not glucagon.

Okay. You seem to have pretty -- so far looks like you have pretty rapid weight loss at the beginning. I'm assuming this is not linear, right? So it'll start to probably level off. How do you think about the shape of the curve and predictive do you think this early effect is for more of a long-term weight loss?

Sure. Anyway, so this is Scot Roberts. When we look at the totality of the data out there, and this includes the step studies and the surpassed studies, we see a relationship between the initial slope of the weight loss and where the final weight loss ends up. And so we're encouraged because of that, because right now we have that the greatest rate of weight loss, certainly through 12 weeks. Will that slope eventually change over a year? I think that that's likely. But if you look at the data, there is a relationship there, at least we believe strongly. That the bottom is really set by the initial rate.

Interesting, it probably helps an encourages people to stay on drugs and everything, right.

They are saying more of that goes to the dose titration. In fact, that they're getting the full dose right out of the gate and so it happens rapidly. They feel good about that. And then there seems to be this relationship where the [Indiscernible] is already set by the initial slope.

Okay. Then finally can you maybe qualify, how much are you spending on the HepTcell program and is there any interim before the readout next year where you could make a go/no go if you want to continue spending on that program? Just because the majority of the value here from an investment perspective is in the obesity program and HepT cell is just a tough area and unclear commercial opportunity and it's just a difficult space, then difficult for people. Just wondering if you can make a -- some early read and if it's even worthwhile, depending on how much you're spending on it.

Yeah, that's a good question, Liisa, and we track that all the time, so we think towards the end of the year we'll be able to determine. I think main driver is going to be the rate of enrollment, it's a very difficult trials to enroll, particularly in the COVID setting, because these are international studies and COVID keeps flaring up in different parts of the world so things shutdown. So we hear you and we -- at this point, as you can do the math, most significant spend or most of the majority of the spend is on pemvidutide here. So we think there is value to finishing that study because without that study you really cannot make the argument about combining HepTcell with another antiviral. So we need that data, but we'll evaluate that at the end of the year. And if we need additional flexibility, clearly, that's a level that we can pull at that point.

Okay. Thank you, guys.

Thank you. Our next question will come from Mayank Mamtani with B. Riley Securities.

Good morning, team. Thanks for taking our question. So for conference data presentation this quarter, could you talk to what we should focus on in terms of understanding the differentiating attributes of [Indiscernible], but also maybe specifically at ADA of what might be the datasets that weren't maybe part of Lilly's outlined press release, just things that you're looking out for at ADA? And then I will couple of follow-ups.

Scott.

So Mayank, thanks for the question. We'd highlight the differentiating features our number one, the potential to achieve even higher levels of weight loss with pemvidutide than the other compounds that have been studied both so far as Scott mentioned in his reply earlier, the rate of weight loss initially leads us to believe that the final weight loss that we will achieve will be higher, we're very optimistic about that. Second, we think the absence of dose titration is extremely important because we think that that's right there where the pen hits the prescription pad. And physicians are going to prefer this much more to regimens that they have to follow over five-nines with a physician extender or some other kind of help. And then the primary care setting when the primary care doctor has eight minutes in front of the patients, to manage this is really not feasible and it's only going to get worse. And finally, we think we differentiate strongly on lipids because the effects of GIP in GLP-1 are mediated indirectly through weight loss. The lipids are mainly a hepatic event and as you know, we have tremendous reductions in liver fat. That also represents the mechanism for the serum lipids and that's why the serum lipids decrease so much. That's the direct effects of glucagon on the liver and the lipids, which is well described in the literature. So we think that for lipid reduction, which is what physicians are going to focus on, they're going to see pemvidutide as having superior attributes. We're seeing effects on lipids that are similar to statins and fibrates in terms of reduction in total cholesterol, LDL cholesterol, and triglycerides. With regards to ADA, obviously, there's going to be other compounds that are being presented at that time. I'm expecting to see some data from a literally and they're dual and triple agonists. We'll have to wait and see if and what they present. And that will be up extreme interest as well to us. But we'll be on the podium. We'll be presenting the results of our Phase 1 trial. Sam Klein, who is extremely well known name in obesity research from Washu will be presenting that and we're really looking for great session.

Great. Thanks for that color. And then now that you have some cost savings from the 52 week NASH study and you talk about this broad guided metabolic benefit. I was just curious, maybe it's still early days, but we are hearing ingredient therapies, getting to see the outcome trials. Is that part of your plan? Initial discussions and is that in any way big [Indiscernible] as you think about the Phase 3 trial design, 2022, 2024 onwards.

Well, thank you for the question Mayank, as you know, the CV outcome trials are trials that you do predominantly after approval. And maybe even in this space now exclusively after approval. So all their eyes are on it, it's something that's really not on the drawing board right now. At this point in time, we're looking at the surrogate markers, which are -- should be very predictive of the outcomes and that would be the lipids. I mean, that's your best marker of cardiovascular risk that we have. So at this stage of development and the absence of an outcome straw, which is some time away, we'd be focusing on the lipids and it looks really good.

Yeah, the other part I would just add Mayank is that once we have the Phase 2 data, our focus would then shift to immediately having an end of Phase 2 meeting with the FDA, so that would be another important milestone. That's really going to be our first substantative discussion with the FDA on the Phase 3 plan for pemvidutide for obesity.

And just my final -- that's a good question on MOMENTUM. So now you'll add 25 sides, any chance you are able to comment, how these sides compare to other [Indiscernible] studies in terms of patient enrollment per month, how it ramps up as -- you know, things of that sort, screening to dosing. I mean, do you see any issues of competitive enrollment or running placebo-controlled trials as an issue in the future and if like not having titration is critical element of enrollment, not just real world prescription later on.

Thanks, Mayank. There's several parts of that question. Let me make -- let me try to hit on them, and if I don't backfill slowly, please ask your question again. Regarding the sites that we have in the trial, each of those sites are accomplished sites in obesity, each IFA track record, not only on enrollment -- in rapid enrollment, but also retention, which is very important because we're focusing on that. There is a tremendous -- and I want to emphasize this, tremendous amount of investigator enthusiasm. Investigators want to be in this space, and boy, patients really want to be in these studies. There's always a challenge in these studies of keeping people in the studies, particularly, the placebos. So the enthusiasm in the investigator and the enthusiasm that's given to the patient to stay in the trial with lots of attention, help with their lifestyle, management of the like, is extremely important. The ability to keep the placebos in the trial are important as well. None of these sites have competitive studies, and we don't think that the prep -- the titration or the absence of it is any issue, if anything it's a plus because patients are looking forward to more rapid weight loss when they come into the program. And that's why they're coming in as the potential for the more rapid weight loss and the greater weight loss.

Harris, thanks for taking our question.

Sure.

Thank you. Our next question will come from Jonathan Welandon with JMP Securities LLC.

Thanks for taking the question and congrats on the progress. I guess, I have a little question on just want focus on obesity, which we appreciate, but also understanding the opportunity in NAFLD. I think means more in your hands that someone else's and how do you have these discussions with strategies if you are successful in obesity won't that, pardon the pun, eat into a NAFLD opportunity? Just wondering how someone else would think of how [Indiscernible] could be used in NASH if you're out there in obesity as well.

Yeah. No, that's a good question, Jonathan. Let me just say this that we've always said that the path to treating NASH is through obesity. So if you look at other players that are working in GLP-1 space or GLP-1 -- GIP space as well, they're all following both obesity and NASH. We think the data that we have generated so far on FLD speaks for itself and the data that we will generate will be sufficient to connect the dots between obesity and NASH, so just pursuing obesity doesn't exclude due from pursuing NASH. So whoever we partner with, ultimately we think they would value NASH in addition to the obesity indication. And really that would be the ideal way for us to proceed with both those indications in parallel. By the way, we will be ready to execute a Phase 2 NASH study as soon as possible. So we're making all the preparations, we're not putting the pen down. We just not going to -- going to undertake major expense and start the study, but we'll be ready to pull the trigger on that, which we think has value. So we are preparing for all that needs to be done in order to start that study as quickly as possible.

Got it. I guess to that and Richard, I kind of missed in the prepared remarks, the 2022 guidance, I was hoping you could run through that one more time.

Sure. The -- I just want to get to operating cost guidance, Jonathan. R&D expenses for the year projected to be about $75 million for the full-year, so that's inclusive of the $15 million we've spent in Q1, and then G&A is around $19 million in expense. And of all that expense, about $8.5 million of that is non-cash.

Very helpful. Thanks again.

Thank you. Our next question will come from Patrick Trucchio with H.C. Wainwright & Co., LLC.

Good morning, team. This is [Unidentified Analyst] on for Patrick. And so I have a couple of questions on the HepTcell program. So the first one is, what do you -- what do you view as ideal antivirals combined with HepTcell and what is the current status of potential collaboration on HepTcell? And then I have two follow-up questions after that.

You will take that?

Yeah, Scott?

Hey, [Unidentified Analyst]. I think that from a combination standpoint, certainly agents that knockdown surface antigen are the most likely candidates. I think that we look towards the RNA type of inhibitors. Those are the natural selections. There are others that are out there, whether that other nucleic acid approaches. The capsids may have some use, but I think we're really focused on significant knockdown of surface antigen creating a window, a better opportunity then for HepTcell to go in and activate those T-cells.

Okay, great. So to look forward to the data readout for first the half are we basically anticipating for clearances surface antigen initial dataset?

Yes. And I think in terms of your question about partnering status, that goes hand-in-hand. We've got initial discussions with folks pending the data. So it's really a question of who do we combine with and it's for them as well as for us, which is the best combination and that would only be determined after we have the data.

Okay, great. That's really helpful to know. And then the last question about HepTcell. Will we have a new functional cure rate in the initial data or will we wait for another six months to fully assess, and what rate of functional cure would you anticipate in this trial?

Scot.

Yeah, the trial's really not set up to look at a functional cure. This is meant to look at a neurological endpoint. We think that that's the data we need to take, the next important step in the program. So it's really not focused on functional cures. Certainly, we'll be looking for that, would not go beyond that. Again, the study is focused on the neurological endpoints, validating the approach, and setting us up then for a combination study that I think everybody who's in this area understands is really going to be the successful path forward.

Great. Thank you so much.

Thank you. It appears we have no further questions at this time. I would now like to turn the program back over to our presenters for any additional or closing remarks.

Yes. Thank you, everyone for participating today. We appreciate this opportunity to share our results and outlook with you and thank you for your continued interest. Have a nice day.

Thank you, ladies and gentlemen. This concludes today's event. You may now disconnect.
