Greetings and welcome to the Vaxart Business Update and Fourth Quarter and Full Year twenty twenty four Financial Results Conference Call. A question and answer session will follow management's opening remarks. Individual investors may submit written questions to irbacksart.com. As a reminder, this conference is being recorded. I would now like to turn the webcast over to your host, Ed Berg, Senior Vice President and General Counsel.

Speaker 1

Good afternoon, and welcome to today's call. Joining us from Vaxart are Stephen Lowe, Chief Executive Officer Doctor. Sean Tucker, Founder and Chief Scientific Officer Doctor. James Cummings, Chief Medical Officer and Philip Lee, Chief Financial Officer. Before we begin, I would like to remind everyone that during this conference call, Baxart may make forward looking statements, including statements about the company's financial results, financial guidance, its future business strategies and operations, and its product development and regulatory progress, including statements about its ongoing or planned clinical trials.

Speaker 1

Actual results could materially differ from those discussed in these forward looking statements due to a number of important factors, including uncertainty inherent in the clinical development and regulatory process and other risks described in the Risk Factors section of Vaxart's most recently filed annual report on Form 10 K and also on other periodic reports filed with the SEC. Vaxart undertakes no obligation to update any forward looking statements after the date of this call. I'll now turn the call over to Stephen Lowe. Steve?

Speaker 2

Thanks, Ed, and thanks to all of you for joining us this afternoon. On today's call, I will highlight our business progress. I'll then have James and Sean share updates on our clinical and preclinical programs. Then Phil will discuss our financial results before we open the call for your questions. At Vaxart, our mission is to transform global public health by developing next generation oral pill vaccines to support pandemic preparedness and provide Americans and people around the world with a revolutionary new option to how they receive vaccines.

Speaker 2

Vaxart built a robust body of data across multiple clinical studies and we believe that our approach may provide important safety and immune response benefits compared to approved injectables. We have multiple programs in clinical development built on the strength of our oral vaccine platform. It is this platform that has generated promising data to date, harnessed in a pill formulation that can address many of the shortcomings of injectable vaccines. Our candidates have demonstrated broad immune and cross reactivity responses, reduction in viral transmission and shedding, long duration of protection and immune responses, and importantly, a benign safety and tolerability profile. Across 19 clinical trials against seven different viruses evaluating more than 800 participants, our vaccine candidates have shown favorable safety data.

Speaker 2

Starting with our COVID-nineteen program, as we stated previously, we received an award of approximately $460,000,000 to conduct an approximately 10,000 participant head to head study against an available mRNA comparator. In November 2024, we completed enrollment of the initial SENTINEL cohort of the study comprised of 400 participants, with 200 receiving Vaxart's XBB strain COVID-nineteen vaccine candidate and 200 receiving an approved XBB mRNA vaccine comparator. In January, an independent Data Safety Monitoring Board recommended the study to proceed without modifications based on initial safety assessment of the thirty day data. On February 21, we received a stop work order related to this BARDA funded Project Next Gen award from the U. S.

Speaker 2

Department of Health and Human Services or HHS. We were not provided a reason for the stop work order. It halted all activities related to the planned 10,000 participant portion of the study and is in effect for a period of up to ninety days. Within these ninety days, the stop work order will either be canceled, extended or work on this project will be terminated. To be clear, this does not apply to efforts associated with the 400 person SENTINEL cohort of the study and activities to monitor and further assess this cohort continue.

Speaker 2

Vaxart is aligned with HHS and BARDA's vision of improving efficiencies, while protecting Americans from known and emerging disease threats, underscored by the progress we achieved with our oral vaccine pill candidates. We recognize and appreciate the importance of oversight, transparency and fiscal responsibility in government funded biomedical research, and we are committed to working collaboratively with Secretary Kennedy, HHS, BARDA and other members of President Trump's administration as they evaluate their priorities as well as the data supporting the 10,000 participant portion of the Phase 2b study and determine whether and how the study should move forward. We maintain ongoing communications with our contacts at BARDA, primarily as it relates to the Sentinel Group follow-up work. At this time, we do not have any new updates to provide on the 10,000 participant portion of the trial. We will provide an update when we have additional information.

Speaker 2

The company continues to work through the impact of the stop work order, including making necessary expense adjustments in order to extend our cash runway. Turning to our norovirus program, we are making meaningful progress on our key milestones and we are pleased to have initiated a Phase one trial earlier this month, evaluating our second generation oral norovirus vaccine constructs head to head against our first generation constructs. We believe this was a prudent and responsible path that aligns with the recommendations of FDA based on constructive conversations that we previously held with the agency. If the Phase one trial is successful, the next step pending a partnership or other funding would be to conduct a Phase two safety and immunogenicity study that could potentially begin as early as the second half of twenty twenty five. This Phase II trial would be followed by an end of Phase II meeting with the FDA.

Speaker 2

A Phase III trial could then begin as early as 2026 pending a successful end of Phase two meeting and funding. Currently, there are no approved vaccines against norovirus. This winter was particularly challenging with numerous reports of norovirus spreading across The United States and around the globe. Norovirus is not just a cruise ship virus, but one that is highly contagious and is the leading cause of acute gastroenteritis symptoms such as vomiting and diarrhea. This $10,000,000,000 annual U.

Speaker 2

S. Economic burden can affect up to approximately twenty million Americans, further illustrating the unmet need that we are determined to meet. Finally, we continue to carefully review our preclinical programs before determining if further investment is needed to advance other indications. Two such indications that we are evaluating are our avian influenza and HPV vaccine programs. Sean will provide an update on these programs shortly.

Speaker 2

I'll now turn the call over to James to provide a further review of the recent progress for our norovirus program.

Speaker 3

Thanks, Steve.

Speaker 4

Vaxart continues to make important advancements with our promising norovirus vaccine candidate in clinical development. Earlier this month, we initiated a Phase one clinical trial evaluating our second generation oral norovirus vaccine constructs head to head against our first generation constructs. Sean will discuss our new constructs in more detail shortly, but this is an exciting study that will measure safety and immune parameters that have been correlated to protection in the completed norovirus challenge study. I want to remind you of why we took this approach. By accumulating data from our first generation constructs, we measured efficacy against a robust controlled human infection model and identified important immune markers that track with norovirus protection.

Speaker 4

Importantly, our norovirus oral vaccine candidate has shown that it induces mucosal and systemic immune responses and has generated protection that associates with making a functional antibody response to norovirus in the serum and norovirus specific fecal IgA antibodies. Last year, our Phase II challenge study demonstrated encouraging data on the potential of our oral pill vaccine to reduce rates of norovirus infection, illness and viral shedding. Additionally, in our Phase one clinical trial that focused on lactating mothers, we demonstrated positive data that suggested our vaccine candidates can potentially help protect infants through passive antibody transfer. In addition to the robust immunogenicity and promising efficacy profile, our norovirus program has demonstrated a benign safety and tolerability profile consistent with the safety of our platform in previous studies. As previously exhibited in our CHALLENGE study, there were no significant differences in adverse events between our vaccine candidate and placebo.

Speaker 4

Now, we have promising preclinical data for our norovirus G11 and G24 constructs that we believe may be more potent than the first generation constructs being evaluated in clinical trials. We are testing this hypothesis to allow us to move forward with the right dose of the right construct. The combined preclinical and clinical data along with the constructive feedback on the correlative protection data we submitted gives us optimism that we will have the most effective and safe norovirus vaccine candidate in clinical development. We look forward to reviewing the top line neuro data that is expected as early as mid-twenty twenty five. I'll now hand the call over to Doctor.

Speaker 4

Sean Tucker, our Founder and Chief Science Officer, for a brief discussion of our norovirus second generation constructs, recent publications and preclinical programs. Shawn?

Speaker 5

Thank you, James. First, I'll highlight the research into our second generation vaccine constructs and discuss in greater detail the results of our recent publications in science translational medicine. Through the power of machine learning, we created new second generation norovirus G1one and G2four constructs. In preclinical testing, our data show our new constructs are more potent than the first generation norovirus constructs we previously evaluated in clinical trials. The second generation constructs are designed to express the antigenic protein at higher levels in the intestinal space, the site of delivery of our vaccine after release from the tablet.

Speaker 5

We were able to improve expression by small changes in the DNA sequence. In preclinical models, this higher level expression has led to substantially improved immune responses compared to our first generation constructs. Further, these new constructs take advantages of recent changes in the backbone design to improve RNA stability. Our expectation is that the improvements will translate to better performance in humans either by eliciting more robust immune responses or by creating a similar response at a lower dose, also known as dose sparing or both. As James mentioned, we look forward to showcasing the potency of our new constructs against our first generation constructs in a Phase one study that we initiated earlier this month.

Speaker 5

On March 5, Science Translational Medicine published two articles on our norovirus studies that will underscore the efficiency of our platform in generating mucosal antibody responses. I'll start with our Phase 1b trial that evaluate safety and immunogenicity of our first generation oral norovirus vaccine candidate in two groups of healthy older adults, age 55 to 65 and 66 to 80 years old. We announced the data in a press release, but I would like to highlight a few key findings from the study. First, the vaccine candidate generated robust and durable systemic antibody responses induced VB1 specific mucosal homing antibody secreting B cells and mucosal homing T cells. These data support immunogenicity of our vaccine candidate in a patient population that often has age related reductions in immune responses to injected vaccines.

Speaker 5

Second, oral administration of the vaccine stimulates strong and durable IgA responses in the saliva and the nasal cavity, which could have important implications for use of our vaccine platform for norovirus and other indications as well. And third, the vaccine was safe and well tolerated in older adults. All solicited events were mild to moderate with no grade three events related to the vaccine. Based on these results, our oral pill norovirus vaccine program may be uniquely positioned to protect elderly individuals from adverse norovirus infection outcomes and prove to safely provide the benefits of the mucosal vaccine to patients at higher risk of adverse norovirus outcomes. The second publication in Science Translational Medicine focused on identifying broadly neutralizing antibodies targeting the human norovirus and to determine the biochemical and structure basis of broad humoral protective immunity.

Speaker 5

The majority of this work was performed by two academic groups, one at UT Austin and one at the University of North Carolina. Two donors were selected for detailed studies. Both candidates received a single dose of our oral candidate vaccine to G2-four and were selected based on their post vaccine immune responses to norovirus. In participant A, vaccination substantially boosted ligand binding blocking serum titers to all tested G2-four variants circulating from 3.5 to 68 fold increase on day twenty nine compared with pre vaccination serum collected on day one. Serum for participant B had exceptional cross genotype blocking serum breadth across seven gs2 and two gs1 genotypes on day one before vaccination and were modestly boosted from two point zero to 3.6 fold at day twenty nine after vaccination.

Speaker 5

Data suggests that immune imprinting largely affects the response to mucosa norovirus vaccination in adults creating a highly cross reactive response rather than a simple strain specific response due to prior norovirus exposure. The oral vaccine likely enhanced those cross strain responses. Indeed, several monoclonal antibodies were isolated from oral vaccinated subjects and many of those antibodies refined to bind to conserve epitopes of norovirus and led to that cross reactivity. We believe these data published are highly compelling from both efficacious and safety standpoints and support the continued advancement of our PROMIS norovirus vaccine candidate. I would like to take this time to thank our incredible R and D team and our collaborators for support in conducting these studies and making these publications possible.

Speaker 5

As Steve mentioned earlier, we are reviewing our preclinical programs in terms of the next steps of bringing future candidates into the clinic. On avian influenza, we published data demonstrating protection of preclinical model after oral immunization and recently created a new vaccine candidate to cover the latest CLAID 2.3.4b strain. We're in the process of conducting several preclinical studies to evaluate the new construct and preparing to manufacture it for clinical use. On our HPV vaccine, we have additional preclinical studies planned to further characterize immune stimulating anti tumor activity this candidate. Previously published data suggested our mucosal vaccine platform represents a possible non invasive approach to prevent the progression to cervical cancer.

Speaker 5

We will publish the results for preclinical studies when complete. I'll now hand the call over to Phil Lee, our CFO, for a brief discussion of our financials. Phil?

Speaker 3

Thank you, Sean. The details of our full year 2024 financial results are summarized in today's press release. Revenue for 2024 was $28,700,000 compared to $7,400,000 in 2023. Revenue in 2024 was primarily from government contracts related to BARDA and non cash royalty revenue from sales of INNOVERE in Japan. Revenue in 2023 was primarily from revenue recognized for work performed under Vaxart's grant from the Bill and Melinda Gates Foundation and non cash royalty revenue from sales of INNOVIR in Japan.

Speaker 3

Vaxhar ended 2024 with cash, cash equivalents and investments of $51,700,000 In the first quarter of twenty twenty five, the company implemented measures to reduce expenses, including a reduction in its workforce following the BARDA stop work order. Based on our current plan, Baxar anticipates cash runway into the fourth quarter of twenty twenty five. Vaxart continues to explore various strategies to extend its cash runway through strategic partnerships, non dilutive funding and other cost reduction initiatives. I will now turn the call back to Steve for closing remarks.

Speaker 2

Thank you, Phil. The team here at Vaxart is dedicated to reimagining the way global public health is approached. Advancing vaccine development is a time and capital intensive process that we are pursuing to ensure our vaccines are not just highly effective, but safe. Our unique strategy centered on mucosal immunity is a cornerstone of our vision for success, and we believe that our benign safety and tolerability profile reinforces our confidence in our science. As trailblazers in oral vaccines, we take pride in bringing groundbreaking innovations to the field.

Speaker 2

The desire to shield people from infectious diseases and promote longer, healthier lives fuels our team's passion every day. We look forward to sharing our progress with you in 2025 and beyond. Before we open the call for questions, we request that listeners do not ask questions related to the HHS stop work order directive. As we stated earlier, we do not have any additional information to provide at this time and so cannot comment further on this matter. We appreciate your understanding.

Speaker 2

Thanks everyone for your time today. We will now open the call for your questions.

Operator

Thank you. We will now be conducting a question and answer session. Our first question comes from the line of Chang Lee with Oppenheimer. Please proceed with your question.

Speaker 6

Hi. Thanks for taking the question and congrats on the progress as well as the publication on Science Translational Medicine. Just a couple of questions from us regarding the new Phase one study for norovirus. I'm wondering if you can talk about whether the new or second generation product is bivalent or it's a monovalent vaccine? And then for the Phase one study, whether you are planning to enroll both young adults and older adults in the trial?

Speaker 6

Thank you.

Speaker 2

Yes. Hi, Sean. Thanks for the question. I'll let James and Sean answer that. James, if you want to go first.

Speaker 4

Sure. Thanks, Steve. So, Shane, for the Phase one study, we are enrolling folks 18 40 nine into the study population. In terms of the second generation product, we are looking at a G11 and a G24 and I'll bounce it off to Sean for a little more definition in terms of what the second generation product might be. Sean?

Speaker 7

Sure. Yes, we made some small changes to the DNA backbone as well as this antigen sequence and we've found that those changes led to and they were very minor changes to enhanced expression in intestinal epithelial cells. And once we put those constructs into preclinical models, we found that the animals made much greater immune responses to the antigen of choice than our first generation. Obviously, we're very bullish and have moved this forward into the clinic.

Speaker 6

Got it. Thank you. And just maybe a quick follow-up. Can you maybe provide some color on the scope of the top line data we should expect in media? Thank you.

Speaker 4

I'll take that, Sean. So in terms of the top line data that we'd be looking for, it's safety and preliminary safety and immunogenicity.

Operator

Thank you. Our next question comes from the line of Mayank Mamtani with B. Riley Securities. Please proceed with your question.

Speaker 8

Hey guys, Madison on for Mayank. Thank you for taking our questions. Curious regarding the second generation version, the animal data that you've referenced, we see this greater immune response. Just wondering how this could translate to top line efficacy relative to what we've seen from the prior first gen? And then also wondering, will the data generated from the first gen still contribute to FDA discussions?

Speaker 8

Thanks.

Speaker 2

Yes. Thanks for the question. I'll go ahead. I was going to let James and Sean go and take that. From our standpoint, right, even the first construct, first version, we had pretty good results.

Speaker 2

But please go ahead, James.

Speaker 4

Actually, I'll have Sean go first and I'll back clean up. Sean?

Speaker 7

Yes. So, yes, the new constructs, we know that they make better immune responses in animals. And again, our expectation is that even like a small change in humans because of the exponential amplification of the signal will make a big difference from the standpoint of protective efficacy. Again, this is through mathematical modeling. We think we know what antibodies are needed in the intestinal space as well as when we measure it, the serum, and we think that just the small increases would be phenomenally better from the standpoint of efficacy.

Speaker 7

I'll let James answer the regulatory question.

Speaker 4

Thanks, Don. And from a regulatory standpoint, finding the right construct, the right dose moving forward is the key for us. I think that it will be part of the overall discussion as we want to pick the best vaccine to bring to people to protect them.

Operator

Thank you. Our next question comes from the line of Liang Chang with Jefferies. Please proceed with your question.

Speaker 9

Hey, good afternoon. Thank you for taking our questions. This is Liang Chang for Roger Tsong. Song. I guess my first question is about the Novartis program, so congrats on your progress initiating the Phase one study.

Speaker 9

So understanding that's going to be head to head study versus your first gen construct. So I guess for the top line readout, so what immunogenicity measurement should we focus on and how would you expect that translate into the protection efficacy?

Speaker 7

Yes. I would say the two things that we're going to measure initially from that study are we're going to measure the serum, what we call NBAA response, norovirus blocking antibody assay fighters. We know that that in our clinical study or the challenge study, we know that that correlated with protection pretty well. And the other thing we're going to measure is going to be the fecal IgA. And again, that also was part of the top line data that is most important from the standpoint of showing efficacy in that CHALMZ bottle.

Speaker 9

Thanks, John. Maybe a follow-up question. So regarding the second generation construct, so you mentioned that the stronger potency. So how should we think about that regarding the dose that are going to be used in a clinical study compared to first generation?

Speaker 4

Sure. I'll take that, Sean. So we're enrolling a total of 60 patients in the Phase one trial in three separate cohorts of 20. So in taking a look at the new construct, it would be considered low dose and high dose and then the traditional or the original construct would be considered the high dose looking at both G11 and G24. Our enrolling takes into account the best practices for safety dose and for clinical development.

Speaker 4

And it's I'm happy to say it's progressing smoothly.

Speaker 9

Thanks, James. Maybe final question regarding the COVID-nineteen program. So understanding that the DSMB have seen the data and recommended go ahead without any change. So has FDA ever seen the data for the Sentinel cohort?

Speaker 4

Yes. This is James. The data was sent to the FDA at the same time it was sent to the DSMB.

Speaker 9

Got it. Thank you. That's it from us. Congrats again.

Speaker 7

Thank

Speaker 1

you. Thank you.

Operator

And we have reached the end of the audio question and answer session. I'll now turn it back over to Ed Berg for the written questions.

Speaker 1

Thank you. We have a number of questions that have been submitted by our shareholders. The first question, this one clearly is for Steve. Are you managing the company differently given the challenging and rapidly evolving regulatory and political environment?

Speaker 2

Great. Thanks for the question. We're a small company, so we always operate in a very lean fashion and we also pride ourselves in being nimble and adaptable and we'll continue to do so. As the listeners know, the science of vaccines represents a big achievement in modern medicine. So they're one of the most powerful tools in combating infectious diseases, safeguarding against safeguarding public health, etcetera.

Speaker 2

And we all know vaccines have profoundly reduced illness and death rates around the world. We still consider Vaxart to be an innovator in this field given our oral vaccine platform. It's demonstrated a clean safety profile to date that's similar to placebo. And it's that type of differentiator that we believe could assist with the acceptance of vaccines, allowing consumers and physicians to have more options. We're certainly appreciative of our working dialogue with FDA, BARDA and HHS.

Speaker 2

Our plan in 2025 has always been to advance more than one vaccine program and we're happy to report that we continue to do so.

Speaker 1

Thanks. A couple of questions on the COVID-nineteen program. The first one is about the DSMB. Did they provide specific feedback? And then maybe James, you can also cover sort of how we think about the FDA submission if anyone is unclear.

Speaker 1

But for James both around sort of what has occurred with regard to the monitoring and the oversight of the program from the scientific bodies?

Speaker 4

Thanks, Ed. So the DSMB, as we mentioned, reviewed thirty day safety data on 400 participants from our single cohort of the COVID-nineteen Phase 2b study. And they recommended very clearly after review of that data that the study proceed without modification based on their assessment. And we believe that this recommendation underscores that really the robust safety profile of our vaccine candidate in and of our platform, again, very similar to placebo. In terms of submission to the FDA, that data was sent forward to the FDA at the same time and they've reviewed that data.

Speaker 4

And so there's no hold on that in terms of moving things forward. From our standpoint, it's we're tracking for continuing the program. Over.

Speaker 1

Thanks, James. The next question, how does the stop work order impact manufacturing? Was the product already produced for the trial? If so, what's the shelf life? Can it be salvaged if the stop work order lasts the full ninety days or later?

Speaker 1

So a set of questions around manufacturing and the use of the product we've produced. And with that, I'll ask Ray Stapleton, who is our Chief Technical Officer

Speaker 10

to answer for us. We have him here. Thank you, Ed. We're fortunate that we maintain our own GMP manufacturing facilities and they are all inside The United States. These capabilities have allowed us to pivot quickly in support of this trial.

Speaker 10

This was demonstrated when we initially manufactured product targeting the XBB strain of COVID and subsequently manufactured product targeting the KP2 strain of COVID. As part of our ongoing manufacturing plan, we routinely monitor product stability. And based on our stability data across our platform to date, shelf life is expected to last for two years. As we obtain clarity on the stop work order, we remain confident that we can adjust to it.

Speaker 1

Thanks, Ray. Next question is on our neurovirus program, and this is about how do we think about the market opportunity given there is a competitor already in Phase three and I'll ask Steve to answer that.

Speaker 2

Sure. Thanks for the question. I think any time a large company with lots of resources believes that there is a significant unmet need, we're encouraged by that because we see it the same way as well. So, yes, there is a significant market opportunity for norovirus, which has $10,000,000,000 impact to The U. S.

Speaker 2

And we certainly believe that consumers and physicians will appreciate having options for future vaccines. Obviously, we believe an oral option is going to be competitive in the marketplace. And as we've been talking about earlier, we're excited that we are on track to have some top line data in our Phase one as early as mid year this year.

Speaker 1

Thank you. Questions on our other programs for Sean. First, when can we expect updates with regard to your preclinical studies in influenza and HPV? And then follow another question separately, is there a way for Vaxart to expedite work on the bird flu vaccine?

Speaker 7

Great. Thanks. Well, the company is in the process of conducting several preclinical studies to evaluate our second generation construct and is also preparing to manufacture those constructs for clinical use. Obviously, we will publish the results when the preclinical studies are complete.

Speaker 1

Thanks. And we have a question on finance. What partnership or non dilutive funding options are you considering? I'll ask Phil to answer that.

Speaker 3

Thanks, Ed. So we have and we really do continue to engage and really update certain parties as we make progress on our programs and platform. We also additionally participate in both financial and scientific conferences where we do connect with new third parties. We are just in general really encouraged that a number of these parties continue to show interest in our vaccine candidates and really the promise of the oral pill vaccine platform. We while we cannot provide further details at this time, we certainly will make announcements when it's appropriate and we have something to say.

Speaker 1

Thank you, Phil. That concludes the questions that have been submitted. With that, I'll turn it back over to the operator to close our session. Thank you. And ladies and

Operator

gentlemen, this does conclude today's conference. You may disconnect your lines at this time. We thank you for your participation.
