Operator00:00:00Greetings, and welcome to the Vaxart Business Update and Second Quarter 2023 Financial Results Conference Call. A question and answer session will follow management's opening remarks. Individual investors may submit written questions to irvaxar.com. As a reminder, this conference is being recorded. I would now like to turn the webcast over to your host, Brandt Bann, Senior Vice President and Business Operations. Operator00:00:28Thank you. You may begin. Speaker 100:00:32Good afternoon, and welcome to today's call. Joining us from Vaxart are Andre Florio, our Chief Executive Officer Doctor. Sean Tom Tucker, our Founder and Chief Scientific Officer Doctor. James Cummings, our Chief Medical Officer and Phil Lee, our Chief Financial Officer. Before we begin, I would like to remind everyone that during this conference call, Vaxart 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 100:01:14Actual results could differ materially 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 ks 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 Andre Glorie. Andre? Speaker 200:01:51Thank you, Brandt, and thank you to all of you for joining us today. On today's call, we will highlight the recent progress we have made on our norovirus oral pill vaccine program. We will also look ahead to our remaining planned milestones for the second half of the year and briefly discuss our COVID program before opening the call to your questions. During the Q2, we are pleased to report positive preliminary results from our Phase 2 dose ranging study for our bivalent Norovirus oral vaccine candidate within our stated time line. James will provide a review of that data and what it means for this potentially groundbreaking vaccine. Speaker 200:02:34It is important to point out All our vaccines are designed to trigger mucosal immunity, and this is a very important distinctive feature of our platform. The clinical data we have generated thus far across our multiple programs suggests that mucosal vaccination could provide several important advantages: broader cross variant protection, reduction in viral transmission, More durable protection and a broader immune response through the activation of both serum and mucosal immunity. The other important distinctive feature of our vaccines is the oral pill format. The potential advantages of Oral pill vaccines are so fundamental that making them a reality could radically change how we think about vaccines and vaccination globally. Oral pill vaccines would allow us to vaccinate a lot more people faster, more easily and painlessly that we are doing today with injectable vaccines. Speaker 200:03:49This vision is the future of vaccination that we are working so hard to achieve. Across FactSet, we are excited about the potential of our norovirus vaccine program. We believe we have the most advanced Speaker 300:04:13intestinal Speaker 200:04:15system. Norovirus is a significant public health issue in developed countries, and there is no approved vaccine. More than 21,000,000 people are infected in the U. S. Each year, resulting in an annual disease burden of more than $10,000,000,000 in the U. Speaker 200:04:32S. Alone. And the virus continues to be a leading subject of infectious disease stories across the country This summer, as the number of cases has spiked to at least a 3 year high, we believe our norovirus vaccine program has the potential to address this need and the significant tremendous disease burden that norovirus carries. Looking ahead, we have 2 important clinical milestones this year, and we remain on track to achieve them both. 1st, We anticipate reporting top line data from the ongoing Phase 2 challenge study of our G11 norovirus vaccine candidate in the Q3 of this year. Speaker 200:05:15And then we look forward to initiating this year The Bill and Melinda Gates Foundation funded clinical trial to evaluate the ability of our norovirus vaccine candidates to induce antibodies in breast milk and transfer of antibodies to young infants. Before I turn the call over to James, I want to provide a brief update on our COVID program. To date, Vaxhar's COVID-nineteen vaccine constructs have demonstrated a favorable immune profile. Vaxhar continues to make progress on this program, and we believe, based on the mucosal cross reactivity data we have seen in our current constraints, That there may be a pathway to develop an oral and beta coronavirus vaccine. We are assessing next steps We'll provide updates as they become available. Speaker 200:06:11Recently, the White House announced a new Office Of pandemic preparedness and response policy. We are very encouraged by the U. S. Government's proactive approach to pandemic preparedness and strongly support Global efforts to get ahead of the next global health crisis. As we cope with the post emergency phase of the pandemic, we must build A cross protective vaccine could improve our ability to fight future pandemics and is committed to that effort. Speaker 200:06:50As you can see, we strongly believe in the potential of our technology and what it could mean for global public health and are excited for the opportunities that lie before us. Now, I'll turn the call over to James for a more detailed review of our norovirus program. Speaker 300:07:09Thanks, Andre. We made significant clinical progress in the Q2, highlighted by the positive Preliminary top line data that we reported from the Phase 2 dose ranging study for our bivalent norovirus vaccine candidate. We believe these data we have seen to date show promise for this vaccine candidate and more broadly our vaccine platform. Recall that this candidate contains 2 genotypes, G11 and G24, both of which have caused the majority of norovirus disease in humans over the past 20 years. As a reminder, this study enrolled 135 Healthy Adults at 3 sites in the United States. Speaker 300:07:55The first 10 Sentinel subjects received open label high dose vaccine And the remaining subjects were randomized to high or low dose vaccine or placebo. Each of the double blinded vaccine arms had 50 subjects And the placebo arm had 25 subjects. The primary endpoints were safety and immunogenicity in order to determine a dose level for Phase 3 development. Now let's take a moment to review the results. As we described in detail in our July announcement, the preliminary results of the trial showed robust serum immune responses Across all doses at day 29 relative to day 1. Speaker 300:08:41Both vaccine doses showed a similar increase in serum antibody With no statistical difference between the medium and high dose arms. At day 29, Increases in serum IGA, serum IGG and BT50 for both the G24 And G11 strains in the vaccine arms were similar to those seen in previous norovirus studies conducted by Vaxart. The results also demonstrate that the bivalent norovirus vaccine candidate was well tolerated With a favorable safety profile that included no vaccine related serious adverse events or SAEs And no dose limiting toxicity. Adverse event rates for both doses were similar to placebo. I'd like to point out that the preliminary data were for serum responses. Speaker 300:09:38Mucosal and cell based assay data will be available at a later date. The totality of the data from this bivalent study and the data we expect from our ongoing norovirus challenge study Will help inform our selection of dosage levels in a larger Phase 2b study and could support an end of Phase 2 meeting with the U. S. Potentially in 2024. I'll now turn to the Phase 2 G11 norovirus challenge study, which is measuring the safety, immunogenicity and efficacy of our monovalent norovirus vaccine candidate. Speaker 300:10:20This study may also help identify a correlate of protection between immune responses to the vaccine and a reduction in the risk of norovirus infection Andor, acute gastroenteritis secondary to norovirus. Enrollment in this ongoing double blinded study It's now completed and we continue to expect to unwind the study and report top line data during the current Q3 of 2023. We continue to believe in the potential of our bivalent norovirus candidate as we proceed toward a BLA submission. We look forward to updating you on our progress in the coming months. I'll now hand the call over to Phil Lee, our CFO for a brief discussion of our financials. Speaker 300:11:07Phil? Speaker 400:11:08Thanks, James. The details of our financial results For the Q2 of 2023 are summarized in today's press release. Revenue for the Q2 of 2023 was $1,400,000 Compared to no revenue in the Q2 of 2022. Revenue in the Q2 of 2023 was primarily from revenue recognized for work performed under Vaxart's grant from the Bill and Melinda Gates Foundation. Vaxart ended the Q2 of 2023 With cash, cash equivalents, restricted cash and marketable securities of $67,900,000 compared to $71,800,000 as of March 31, 2023. Speaker 400:11:55The decrease was primarily due to cash used in operations as we advanced our norovirus program, which was partially offset by $13,600,000 of net proceeds from a public offering completed in June 2023. The offering extends the company's expected cash runway into the Q3 of 2024. On behalf of all of us at Vaxart, I'd like to thank you for your time today. We will now open the call for your questions. Operator00:12:28Thank you. At this time, we'll be conducting a question and answer Our first question comes from Charles Duncan with Cantor Fitzgerald. Please proceed with your question. Speaker 500:13:05Hi, Andre and team. Congratulations on the quarterly progress. So earlier this quarter, you announced Preliminary top line data from the Phase 2 dose ranging study for the bivalent norovirus vaccine candidate That you touched on during the prepared remarks. When you look at the immunogenicity data generated by the study and you compare it to responses observed, let's say, Natural infection to either strain. How do you feel about the response? Speaker 500:13:33And does the data suggest that you need to go lower or higher in dose? Where do you believe you have the right dose in hand? Speaker 300:13:44I'll take that one. Thanks. So we're fairly pleased that the data from that study to date is consistent with previous norovirus study results. You recall in the Preliminary top line data we announced in July, we showed robust serum immune responses across all doses at day 29 relative to 21. The mucosal and the cell based assay data, that's pending and that will be available at a later date. Speaker 300:14:10Once we've assessed that data, I think we can make a stronger decision moving forward. Speaker 500:14:15All right, James. Thanks. And also what are your thoughts on a 1 dose regimen versus a 2 dose regimen for this program? Speaker 300:14:24I think for adults, a one dose regimen. Speaker 500:14:28Right. And as we move into 3Q, we're anticipating seeing data from the Virus tone study. Just wondering if you can sort of lay out what you would like to see perhaps from a qualitative perspective rather Quantitative, that you would find encouraging and would like to take to the agency for the end of Phase 2 meeting? Speaker 300:14:50I don't want to project the data results before we have them. Certainly, if we stay on track with what we've seen in previous studies and note Robust responses from mucosal or cell based assays, that would be very encouraging. And then also we're looking forward to the Data that we should announce later in Q3 of this year in terms of the neuro G11 challenge. That will be inclusive of that for a decision being made as well. Speaker 500:15:19Okay. And just last question, sort of again, I know that you have had you The Phase 2 meeting, but when do you sort of anticipate or expect to operationalize the next study? And do you Backstart driving the program alone forward or you have thoughts of bringing in a partner? Speaker 300:15:39I'll take the first half and then pass the second half off to Andre, if that's okay. I think that from my standpoint, again, we'd like to see The data from this study as well as the 201 challenge study before going to the FDA, The second portion of a study, a larger study, would then lead us to a Phase IIb would lead us to the end of Phase II Discussions with the FDA and as I mentioned before, that could be as soon as 2024. Andre, do you want to comment on the second section of that question? Speaker 200:16:13Sure, sure. So Steve, as our closest competitor in the nonovirus space Silavax has Noted earlier this year, late stage vaccine assets such as the norovirus Programs out of interest to many large pharmas and medium sized pharmas and we'll obviously Entertain those discussions once we have the data. And as you can appreciate, there are advantages and disadvantages To partnering and doing it alone, and we are open to evaluating the options and decide which ones will maximize value And bring the vaccine sooner to patients. Speaker 500:16:59All right. I look forward to the challenge study data and thank you for taking our questions. Speaker 200:17:07Our next question comes from Operator00:17:09Mayank Mamtani with B. Riley Securities. Please proceed with your question. Speaker 600:17:15Good afternoon, team. Thanks for taking our questions and congrats on the progress. So just for the monovalent challenge study, Kind of your execution and enrollment has gone, from what I can tell, faster than your original expectations. So could you just comment The learnings you may have executing on the study and time of the year When you get these infections and how could you apply some of this to additional, Obviously, maybe challenge study work you may have to do with your bivalent or maybe at some point execute on the East and the And Novartis, so we'd love to hear some commentary around that. And then on the Mucosal data that you may look to report incremental to your dose ranging By the way, the data that you already presented in the INDOCE data, could you just remind us what you had seen previously With your prior construct, so that we are able to kind of bracket some scenarios here for what we may I see on IDA and when would you look to kind of present that? Speaker 600:18:34Is there a medical conference you're targeting? Then I have a financial question and follow-up. Speaker 300:18:41Yes. Thanks, Mike. So I'll take the first portion and may have Sean Tucker, our CSO, chime in on the mucosal immunity as he is a world expert in mucosal immunity. So In terms of the learnings from the channel study, recall that the channel studies typically, they're much more aggressive than what you see In nature and the real world. The sample size of this study was built primarily for descriptive statistical analysis as we're looking to understand Really, the mechanics of how this vaccine works. Speaker 300:19:13And to do this, we have a number of measures we're looking at, including a decrease in the severity of Acute gastroenteritis caused by norovirus, a decrease in viral shedding, what our vaccines impact or effect could be on infectivity And then the effect on disease severity. So these are all things I think that from a clinical or global health standpoint are very important. Along with that, we're looking at safety and immunogenicity and the potential for taking a look at what a correlate of immunity might be. For those on the call or listening in, norovirus gastroenteritis is traditionally thought to be more seasonal in presentation. So you certainly have more norovirus by and large for seasonal distribution in the winter months. Speaker 300:20:02That said, There are outbreaks of norovirus that continue really on any month of the year. One only has to take a look at The CDC website here in the United States or the WHO's very robust database or The New York Times to take a look at when outbreaks occur Either in nursing homes or in cruise lines, etcetera. So I think that there is some seasonality to the traditional spread of norovirus, But it is a viral infection that impacts people year round. And because of that, I think it will take a look at executing Challenges in the future, should they be needed, both when the challenge model is available And we think that we have the best opportunity to recruit individuals to move forward in the study. As you mentioned, We're very fortunate to move this study forward and to be able to deliver the data on time. Speaker 300:21:04So we're very excited about that. For the mucosal immunity question, you asked specifically in terms of the I think the what we're looking at in terms of Mucosal immunity for the two zero two study. And for the two zero two study, we don't yet have that mucosal immunity. That would be upcoming, right? And for the historical mucosal immunity, I'd ask Doctor. Speaker 300:21:29Sean Tucker if you'd like to just make a small comment on that I see he ran that program at the time. Sean? Speaker 700:21:36Sure. Yes, it's a good question. So previously, we've reported that We get a mucosal response around somewhere between 2 to 10 fold increases if you're working at fecal or we even talked about nasal responses And you get a number of subjects that respond up to over 90% in terms of ASC count or In terms of the nasal response, if you look at it really carefully. So our expectation is that the G11 will see a similar Mucosal response as well? Speaker 600:22:12Got it. Appreciate the helpful comprehensive So just on the financial runway kind of extension that you guided to 3Q Next year, could you clarify how much incremental non dilutive funding you're baking in there, be it from Melinda Gates Foundation or even the any other forms of government funding? Speaker 200:22:41Ilya, do you Speaker 800:22:42want to Speaker 200:22:42take this? Speaker 400:22:44Sure. So I think in terms of our extended runway guidance, It's really based on our current plans and our existing grant from the Gates Foundation, right? So we Again, once we see the data from the 201 study and really determine the path forward for the study, then we'll kind of determine next steps And incremental spend as needed. But for now, it's all based on our existing plans and existing grant and no new grants at this time. Speaker 600:23:16Okay, got it. Thanks team for taking our questions and look forward to the data shortly here from the challenge study. Speaker 200:23:27Thank you, Operator00:23:35One moment while we poll for questions. Our next question comes from Roger Song with Jefferies. Please proceed with your question. Speaker 800:23:46Good afternoon. This is Liang Chang on Roger Stone. Thank you for taking our questions. Our first question is about the upcoming Phase 2 challenging data. So could you give us some Like color on what would be the go no go decisions for the Phase 2 challenging data? Speaker 300:24:08I can give you some color as opposed to gono go, I think we'd have to talk as a team, but certainly we're looking at Several endpoints and indicators. So looking at a decrease in severity of acute gastroenteritis, I mentioned before that a challenge study It's very aggressive compared to what someone sees in nature. So we're trying to ensure that those who could get sick would get sick, right? But we're looking for a decrease in severity of acute catheteritis secondary to norovirus, potentially a decrease in shedding. And I think that shedding is important because That could then be somewhat of a surrogate for decreasing shedding, you would decrease transmission or you may. Speaker 300:24:51Effect on infectivity, I think is going to be very important. And again, I tie that to viral shedding. And then disease severity, right? So How ill are people actually getting? I think we're looking at all of those items along with the immunogenicity and the safety, But also trying to tease out if we can what a correlative immunity might look like. Speaker 300:25:13And I think those are the things that we're considering as we look at that data set. Speaker 800:25:23Sure. Thank you. This is very helpful. So In terms for the larger Phase 2b study, do we have any guidance and could you provide some colors on the study design? Speaker 300:25:36Sure. So I can give you some thoughts. We would look at the evidence we see or the data that we are seeing from both the two zero two study that we're talking about that data and Some of that data in hand now, but waiting on the UCCOSAL data as well as the impact of the data we see from the 201 challenge And taking a look at both of those, I think we'll be able to determine or help determine what size of the study might look like. One of those factors that may impact it is if we are able to determine a correlate, right? Having a correlate in hand would mean decreasing the size of, if not the Phase 2, certainly the Phase 3. Speaker 300:26:18So Phase 2b study would be larger. You need to have enough people enrolled to ensure that you have a safety That would be acceptable to the FDA. I don't necessarily want to speak with the FDA, but certainly it would be larger than the study we had done now. And we would be Ready to execute once we have those data in hand and have met internally. Hope that answers your question. Speaker 800:26:44Got it. Great. Thank you. Maybe a quick one for Lars. So in terms for the pivotal Phase 3, I know not that probably you don't have much information. Speaker 800:26:55So what age populations would be prioritized, If you can comment on that. Speaker 300:27:03Sure. I'll speak specifically to that question and are generally about the Phase III, right? Again, that Phase 3 would depend on results of the G11 challenge study, the Phase 2b And the end of Phase 2 meeting with the FDA, we take the guidance of the agency literally to heart as we're all, I think, Interested in providing a solution for what is now unanswered, which is there's no approved vaccine for norovirus, Right. I think that we'd address the timing for the Phase 3 once we have more visibility informed by those milestones. In terms of where we're at right now, We have tested in this study the vaccine 18 and older, and I think that's what we're looking for as we march forward. Speaker 300:27:50But That would be dependent. The Phase 3 design would be dependent on conversations with the agency, the FDA. Speaker 800:28:00Thank you. I think that's all from us. Thanks. Operator00:28:07There are no further audio questions at this time. I'd like to turn the call back over to your host, Brent Bien. Speaker 100:28:16Thanks very much. So we had a lot of questions that had been sent in previously ahead of time on various channels. I think most of those have now been asked between Charles and Meg Charles and Meg. So I'm going to Here's one that I don't think has been answered completely yet, James. This one's coming to you. Speaker 100:28:38Do you see any accelerated past commercialization such as an EUA or a smaller Phase 3 study for norovirus and what's a realistic timeline to commercialization? James? Speaker 300:28:49Fair enough. Thanks, Brent. So we continue to address the potential options and the timing for commercialization. Once we have more visibility informed These study results that we're just discussing now. Based on those results, those data and interactions with regulatory agencies, We'll determine the best plan and timeline for commercialization. Speaker 100:29:12That's fantastic, James. Thanks. And another one I don't think we hit on during the call and James, this is also going to be for you. Please remind us what you're looking for in the infant study and potential implications for your norovirus program. James? Speaker 100:29:28Sure. Speaker 200:29:29Thank you. Speaker 300:29:29So it's unknown how norovirus infectivity and spread would be impacted or affected by a vaccine. As I mentioned, there's no currently approved vaccine against norovirus. However, there are some studies that suggest That if you vaccinate children, you can also improve the health of adults. You might not be able to protect against all illness, But we know that children acquire disease and can infect their families. So that's one of the pieces we're looking at. Speaker 100:30:04Fantastic. Thanks, James. So that's the majority of the other Norovirus questions have been asked already and answered by you. So thank you so much for that. I think investors and people on the line that have further questions can take a look at our fireside chat platform on the Investors So at this point, we'll close the meeting. Speaker 100:30:32Thank you. Operator00:30:35This concludes today's conference and webcast. You may disconnect your lines at this time. And we thank you for your participation.Read morePowered by Conference Call Audio Live Call not available Earnings Conference CallVaxart Q2 202300:00 / 00:00Speed:1x1.25x1.5x2x Earnings DocumentsPress Release(8-K)Quarterly report(10-Q) Vaxart Earnings HeadlinesVaxartto Present at World Vaccine Congress Washington 2025 on April 23April 16, 2025 | globenewswire.comVaxart price target lowered to $2 from $2.50 at B.

Before we begin, I would like to remind everyone that during this conference call, Vaxart 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 100:01:14Actual results could differ materially 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 ks 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 Andre Glorie. Andre? Speaker 200:01:51Thank you, Brandt, and thank you to all of you for joining us today. On today's call, we will highlight the recent progress we have made on our norovirus oral pill vaccine program. We will also look ahead to our remaining planned milestones for the second half of the year and briefly discuss our COVID program before opening the call to your questions. During the Q2, we are pleased to report positive preliminary results from our Phase 2 dose ranging study for our bivalent Norovirus oral vaccine candidate within our stated time line. James will provide a review of that data and what it means for this potentially groundbreaking vaccine. Speaker 200:02:34It is important to point out All our vaccines are designed to trigger mucosal immunity, and this is a very important distinctive feature of our platform. The clinical data we have generated thus far across our multiple programs suggests that mucosal vaccination could provide several important advantages: broader cross variant protection, reduction in viral transmission, More durable protection and a broader immune response through the activation of both serum and mucosal immunity. The other important distinctive feature of our vaccines is the oral pill format. The potential advantages of Oral pill vaccines are so fundamental that making them a reality could radically change how we think about vaccines and vaccination globally. Oral pill vaccines would allow us to vaccinate a lot more people faster, more easily and painlessly that we are doing today with injectable vaccines. Speaker 200:03:49This vision is the future of vaccination that we are working so hard to achieve. Across FactSet, we are excited about the potential of our norovirus vaccine program. We believe we have the most advanced Speaker 300:04:13intestinal Speaker 200:04:15system. Norovirus is a significant public health issue in developed countries, and there is no approved vaccine. More than 21,000,000 people are infected in the U. S. Each year, resulting in an annual disease burden of more than $10,000,000,000 in the U. Speaker 200:04:32S. Alone. And the virus continues to be a leading subject of infectious disease stories across the country This summer, as the number of cases has spiked to at least a 3 year high, we believe our norovirus vaccine program has the potential to address this need and the significant tremendous disease burden that norovirus carries. Looking ahead, we have 2 important clinical milestones this year, and we remain on track to achieve them both. 1st, We anticipate reporting top line data from the ongoing Phase 2 challenge study of our G11 norovirus vaccine candidate in the Q3 of this year. Speaker 200:05:15And then we look forward to initiating this year The Bill and Melinda Gates Foundation funded clinical trial to evaluate the ability of our norovirus vaccine candidates to induce antibodies in breast milk and transfer of antibodies to young infants. Before I turn the call over to James, I want to provide a brief update on our COVID program. To date, Vaxhar's COVID-nineteen vaccine constructs have demonstrated a favorable immune profile. Vaxhar continues to make progress on this program, and we believe, based on the mucosal cross reactivity data we have seen in our current constraints, That there may be a pathway to develop an oral and beta coronavirus vaccine. We are assessing next steps We'll provide updates as they become available. Speaker 200:06:11Recently, the White House announced a new Office Of pandemic preparedness and response policy. We are very encouraged by the U. S. Government's proactive approach to pandemic preparedness and strongly support Global efforts to get ahead of the next global health crisis. As we cope with the post emergency phase of the pandemic, we must build A cross protective vaccine could improve our ability to fight future pandemics and is committed to that effort. Speaker 200:06:50As you can see, we strongly believe in the potential of our technology and what it could mean for global public health and are excited for the opportunities that lie before us. Now, I'll turn the call over to James for a more detailed review of our norovirus program. Speaker 300:07:09Thanks, Andre. We made significant clinical progress in the Q2, highlighted by the positive Preliminary top line data that we reported from the Phase 2 dose ranging study for our bivalent norovirus vaccine candidate. We believe these data we have seen to date show promise for this vaccine candidate and more broadly our vaccine platform. Recall that this candidate contains 2 genotypes, G11 and G24, both of which have caused the majority of norovirus disease in humans over the past 20 years. As a reminder, this study enrolled 135 Healthy Adults at 3 sites in the United States. Speaker 300:07:55The first 10 Sentinel subjects received open label high dose vaccine And the remaining subjects were randomized to high or low dose vaccine or placebo. Each of the double blinded vaccine arms had 50 subjects And the placebo arm had 25 subjects. The primary endpoints were safety and immunogenicity in order to determine a dose level for Phase 3 development. Now let's take a moment to review the results. As we described in detail in our July announcement, the preliminary results of the trial showed robust serum immune responses Across all doses at day 29 relative to day 1. Speaker 300:08:41Both vaccine doses showed a similar increase in serum antibody With no statistical difference between the medium and high dose arms. At day 29, Increases in serum IGA, serum IGG and BT50 for both the G24 And G11 strains in the vaccine arms were similar to those seen in previous norovirus studies conducted by Vaxart. The results also demonstrate that the bivalent norovirus vaccine candidate was well tolerated With a favorable safety profile that included no vaccine related serious adverse events or SAEs And no dose limiting toxicity. Adverse event rates for both doses were similar to placebo. I'd like to point out that the preliminary data were for serum responses. Speaker 300:09:38Mucosal and cell based assay data will be available at a later date. The totality of the data from this bivalent study and the data we expect from our ongoing norovirus challenge study Will help inform our selection of dosage levels in a larger Phase 2b study and could support an end of Phase 2 meeting with the U. S. Potentially in 2024. I'll now turn to the Phase 2 G11 norovirus challenge study, which is measuring the safety, immunogenicity and efficacy of our monovalent norovirus vaccine candidate. Speaker 300:10:20This study may also help identify a correlate of protection between immune responses to the vaccine and a reduction in the risk of norovirus infection Andor, acute gastroenteritis secondary to norovirus. Enrollment in this ongoing double blinded study It's now completed and we continue to expect to unwind the study and report top line data during the current Q3 of 2023. We continue to believe in the potential of our bivalent norovirus candidate as we proceed toward a BLA submission. We look forward to updating you on our progress in the coming months. I'll now hand the call over to Phil Lee, our CFO for a brief discussion of our financials. Speaker 300:11:07Phil? Speaker 400:11:08Thanks, James. The details of our financial results For the Q2 of 2023 are summarized in today's press release. Revenue for the Q2 of 2023 was $1,400,000 Compared to no revenue in the Q2 of 2022. Revenue in the Q2 of 2023 was primarily from revenue recognized for work performed under Vaxart's grant from the Bill and Melinda Gates Foundation. Vaxart ended the Q2 of 2023 With cash, cash equivalents, restricted cash and marketable securities of $67,900,000 compared to $71,800,000 as of March 31, 2023. Speaker 400:11:55The decrease was primarily due to cash used in operations as we advanced our norovirus program, which was partially offset by $13,600,000 of net proceeds from a public offering completed in June 2023. The offering extends the company's expected cash runway into the Q3 of 2024. On behalf of all of us at Vaxart, I'd like to thank you for your time today. We will now open the call for your questions. Operator00:12:28Thank you. At this time, we'll be conducting a question and answer Our first question comes from Charles Duncan with Cantor Fitzgerald. Please proceed with your question. Speaker 500:13:05Hi, Andre and team. Congratulations on the quarterly progress. So earlier this quarter, you announced Preliminary top line data from the Phase 2 dose ranging study for the bivalent norovirus vaccine candidate That you touched on during the prepared remarks. When you look at the immunogenicity data generated by the study and you compare it to responses observed, let's say, Natural infection to either strain. How do you feel about the response? Speaker 500:13:33And does the data suggest that you need to go lower or higher in dose? Where do you believe you have the right dose in hand? Speaker 300:13:44I'll take that one. Thanks. So we're fairly pleased that the data from that study to date is consistent with previous norovirus study results. You recall in the Preliminary top line data we announced in July, we showed robust serum immune responses across all doses at day 29 relative to 21. The mucosal and the cell based assay data, that's pending and that will be available at a later date. Speaker 300:14:10Once we've assessed that data, I think we can make a stronger decision moving forward. Speaker 500:14:15All right, James. Thanks. And also what are your thoughts on a 1 dose regimen versus a 2 dose regimen for this program? Speaker 300:14:24I think for adults, a one dose regimen. Speaker 500:14:28Right. And as we move into 3Q, we're anticipating seeing data from the Virus tone study. Just wondering if you can sort of lay out what you would like to see perhaps from a qualitative perspective rather Quantitative, that you would find encouraging and would like to take to the agency for the end of Phase 2 meeting? Speaker 300:14:50I don't want to project the data results before we have them. Certainly, if we stay on track with what we've seen in previous studies and note Robust responses from mucosal or cell based assays, that would be very encouraging. And then also we're looking forward to the Data that we should announce later in Q3 of this year in terms of the neuro G11 challenge. That will be inclusive of that for a decision being made as well. Speaker 500:15:19Okay. And just last question, sort of again, I know that you have had you The Phase 2 meeting, but when do you sort of anticipate or expect to operationalize the next study? And do you Backstart driving the program alone forward or you have thoughts of bringing in a partner? Speaker 300:15:39I'll take the first half and then pass the second half off to Andre, if that's okay. I think that from my standpoint, again, we'd like to see The data from this study as well as the 201 challenge study before going to the FDA, The second portion of a study, a larger study, would then lead us to a Phase IIb would lead us to the end of Phase II Discussions with the FDA and as I mentioned before, that could be as soon as 2024. Andre, do you want to comment on the second section of that question? Speaker 200:16:13Sure, sure. So Steve, as our closest competitor in the nonovirus space Silavax has Noted earlier this year, late stage vaccine assets such as the norovirus Programs out of interest to many large pharmas and medium sized pharmas and we'll obviously Entertain those discussions once we have the data. And as you can appreciate, there are advantages and disadvantages To partnering and doing it alone, and we are open to evaluating the options and decide which ones will maximize value And bring the vaccine sooner to patients. Speaker 500:16:59All right. I look forward to the challenge study data and thank you for taking our questions. Speaker 200:17:07Our next question comes from Operator00:17:09Mayank Mamtani with B. Riley Securities. Please proceed with your question. Speaker 600:17:15Good afternoon, team. Thanks for taking our questions and congrats on the progress. So just for the monovalent challenge study, Kind of your execution and enrollment has gone, from what I can tell, faster than your original expectations. So could you just comment The learnings you may have executing on the study and time of the year When you get these infections and how could you apply some of this to additional, Obviously, maybe challenge study work you may have to do with your bivalent or maybe at some point execute on the East and the And Novartis, so we'd love to hear some commentary around that. And then on the Mucosal data that you may look to report incremental to your dose ranging By the way, the data that you already presented in the INDOCE data, could you just remind us what you had seen previously With your prior construct, so that we are able to kind of bracket some scenarios here for what we may I see on IDA and when would you look to kind of present that? Speaker 600:18:34Is there a medical conference you're targeting? Then I have a financial question and follow-up. Speaker 300:18:41Yes. Thanks, Mike. So I'll take the first portion and may have Sean Tucker, our CSO, chime in on the mucosal immunity as he is a world expert in mucosal immunity. So In terms of the learnings from the channel study, recall that the channel studies typically, they're much more aggressive than what you see In nature and the real world. The sample size of this study was built primarily for descriptive statistical analysis as we're looking to understand Really, the mechanics of how this vaccine works. Speaker 300:19:13And to do this, we have a number of measures we're looking at, including a decrease in the severity of Acute gastroenteritis caused by norovirus, a decrease in viral shedding, what our vaccines impact or effect could be on infectivity And then the effect on disease severity. So these are all things I think that from a clinical or global health standpoint are very important. Along with that, we're looking at safety and immunogenicity and the potential for taking a look at what a correlate of immunity might be. For those on the call or listening in, norovirus gastroenteritis is traditionally thought to be more seasonal in presentation. So you certainly have more norovirus by and large for seasonal distribution in the winter months. Speaker 300:20:02That said, There are outbreaks of norovirus that continue really on any month of the year. One only has to take a look at The CDC website here in the United States or the WHO's very robust database or The New York Times to take a look at when outbreaks occur Either in nursing homes or in cruise lines, etcetera. So I think that there is some seasonality to the traditional spread of norovirus, But it is a viral infection that impacts people year round. And because of that, I think it will take a look at executing Challenges in the future, should they be needed, both when the challenge model is available And we think that we have the best opportunity to recruit individuals to move forward in the study. As you mentioned, We're very fortunate to move this study forward and to be able to deliver the data on time. Speaker 300:21:04So we're very excited about that. For the mucosal immunity question, you asked specifically in terms of the I think the what we're looking at in terms of Mucosal immunity for the two zero two study. And for the two zero two study, we don't yet have that mucosal immunity. That would be upcoming, right? And for the historical mucosal immunity, I'd ask Doctor. Speaker 300:21:29Sean Tucker if you'd like to just make a small comment on that I see he ran that program at the time. Sean? Speaker 700:21:36Sure. Yes, it's a good question. So previously, we've reported that We get a mucosal response around somewhere between 2 to 10 fold increases if you're working at fecal or we even talked about nasal responses And you get a number of subjects that respond up to over 90% in terms of ASC count or In terms of the nasal response, if you look at it really carefully. So our expectation is that the G11 will see a similar Mucosal response as well? Speaker 600:22:12Got it. Appreciate the helpful comprehensive So just on the financial runway kind of extension that you guided to 3Q Next year, could you clarify how much incremental non dilutive funding you're baking in there, be it from Melinda Gates Foundation or even the any other forms of government funding? Speaker 200:22:41Ilya, do you Speaker 800:22:42want to Speaker 200:22:42take this? Speaker 400:22:44Sure. So I think in terms of our extended runway guidance, It's really based on our current plans and our existing grant from the Gates Foundation, right? So we Again, once we see the data from the 201 study and really determine the path forward for the study, then we'll kind of determine next steps And incremental spend as needed. But for now, it's all based on our existing plans and existing grant and no new grants at this time. Speaker 600:23:16Okay, got it. Thanks team for taking our questions and look forward to the data shortly here from the challenge study. Speaker 200:23:27Thank you, Operator00:23:35One moment while we poll for questions. Our next question comes from Roger Song with Jefferies. Please proceed with your question. Speaker 800:23:46Good afternoon. This is Liang Chang on Roger Stone. Thank you for taking our questions. Our first question is about the upcoming Phase 2 challenging data. So could you give us some Like color on what would be the go no go decisions for the Phase 2 challenging data? Speaker 300:24:08I can give you some color as opposed to gono go, I think we'd have to talk as a team, but certainly we're looking at Several endpoints and indicators. So looking at a decrease in severity of acute gastroenteritis, I mentioned before that a challenge study It's very aggressive compared to what someone sees in nature. So we're trying to ensure that those who could get sick would get sick, right? But we're looking for a decrease in severity of acute catheteritis secondary to norovirus, potentially a decrease in shedding. And I think that shedding is important because That could then be somewhat of a surrogate for decreasing shedding, you would decrease transmission or you may. Speaker 300:24:51Effect on infectivity, I think is going to be very important. And again, I tie that to viral shedding. And then disease severity, right? So How ill are people actually getting? I think we're looking at all of those items along with the immunogenicity and the safety, But also trying to tease out if we can what a correlative immunity might look like. Speaker 300:25:13And I think those are the things that we're considering as we look at that data set. Speaker 800:25:23Sure. Thank you. This is very helpful. So In terms for the larger Phase 2b study, do we have any guidance and could you provide some colors on the study design? Speaker 300:25:36Sure. So I can give you some thoughts. We would look at the evidence we see or the data that we are seeing from both the two zero two study that we're talking about that data and Some of that data in hand now, but waiting on the UCCOSAL data as well as the impact of the data we see from the 201 challenge And taking a look at both of those, I think we'll be able to determine or help determine what size of the study might look like. One of those factors that may impact it is if we are able to determine a correlate, right? Having a correlate in hand would mean decreasing the size of, if not the Phase 2, certainly the Phase 3. Speaker 300:26:18So Phase 2b study would be larger. You need to have enough people enrolled to ensure that you have a safety That would be acceptable to the FDA. I don't necessarily want to speak with the FDA, but certainly it would be larger than the study we had done now. And we would be Ready to execute once we have those data in hand and have met internally. Hope that answers your question. Speaker 800:26:44Got it. Great. Thank you. Maybe a quick one for Lars. So in terms for the pivotal Phase 3, I know not that probably you don't have much information. Speaker 800:26:55So what age populations would be prioritized, If you can comment on that. Speaker 300:27:03Sure. I'll speak specifically to that question and are generally about the Phase III, right? Again, that Phase 3 would depend on results of the G11 challenge study, the Phase 2b And the end of Phase 2 meeting with the FDA, we take the guidance of the agency literally to heart as we're all, I think, Interested in providing a solution for what is now unanswered, which is there's no approved vaccine for norovirus, Right. I think that we'd address the timing for the Phase 3 once we have more visibility informed by those milestones. In terms of where we're at right now, We have tested in this study the vaccine 18 and older, and I think that's what we're looking for as we march forward. Speaker 300:27:50But That would be dependent. The Phase 3 design would be dependent on conversations with the agency, the FDA. Speaker 800:28:00Thank you. I think that's all from us. Thanks. Operator00:28:07There are no further audio questions at this time. I'd like to turn the call back over to your host, Brent Bien. Speaker 100:28:16Thanks very much. So we had a lot of questions that had been sent in previously ahead of time on various channels. I think most of those have now been asked between Charles and Meg Charles and Meg. So I'm going to Here's one that I don't think has been answered completely yet, James. This one's coming to you. Speaker 100:28:38Do you see any accelerated past commercialization such as an EUA or a smaller Phase 3 study for norovirus and what's a realistic timeline to commercialization? James? Speaker 300:28:49Fair enough. Thanks, Brent. So we continue to address the potential options and the timing for commercialization. Once we have more visibility informed These study results that we're just discussing now. Based on those results, those data and interactions with regulatory agencies, We'll determine the best plan and timeline for commercialization. Speaker 100:29:12That's fantastic, James. Thanks. And another one I don't think we hit on during the call and James, this is also going to be for you. Please remind us what you're looking for in the infant study and potential implications for your norovirus program. James? Speaker 100:29:28Sure. Speaker 200:29:29Thank you. Speaker 300:29:29So it's unknown how norovirus infectivity and spread would be impacted or affected by a vaccine. As I mentioned, there's no currently approved vaccine against norovirus. However, there are some studies that suggest That if you vaccinate children, you can also improve the health of adults. You might not be able to protect against all illness, But we know that children acquire disease and can infect their families. So that's one of the pieces we're looking at. Speaker 100:30:04Fantastic. Thanks, James. So that's the majority of the other Norovirus questions have been asked already and answered by you. So thank you so much for that. I think investors and people on the line that have further questions can take a look at our fireside chat platform on the Investors So at this point, we'll close the meeting. Speaker 100:30:32Thank you. Operator00:30:35This concludes today's conference and webcast. You may disconnect your lines at this time. And we thank you for your participation.Read morePowered by
