Speaker #2: I'll now turn the call
Speaker #2: Steve, Thanks,
Speaker #3: Ed. And thanks to all of you for joining us this afternoon. I'll begin
Speaker #3: today's call with an overview of our James and Sean for the latest program over to Steven Lo. developments. Jeroen will then share an update of our have some closing comments before we open financials and finally, I will the call for your questions.
Speaker #3: Starting with our COVID-19 clinical program, announce an important value-creating last week we were excited to record in commercializing business, then we'll pass the call to innovative vaccines.
Speaker #3: As part of the agreement, Vaxart could potentially receive up commercial stage biopharmaceutical to $700 company that has a proven track million in total license partnership with Dynavax, a regulatory and milestone fees as well as royalties for our oral COVID-19 vaccine candidate.
Speaker #3: This is a major milestone for the company and this program, which validates the potential of our platform and will provide critical non-dilutive capital that forward.
Speaker #3: Here are some of the will help us advance this program important terms of the agreement. Dynavax will pay Vaxart an upfront license fee of $25 million and make a $5 million equity investment in premium to market pursuant to Vaxart at a per-share price the terms of the Securities Purchase Agreement.
Speaker #3: current cash position, our Combined with our cash runway now extends into the second quarter of 2027. Dynavax will receive an exclusive worldwide license to develop and commercialize oral COVID-19 vaccines based on Vaxart's delivery platform.
Speaker #3: Vaxart will retain full operational and financial responsibility for the oral COVID-19 vaccine program through the completion of the ongoing Phase 2B clinical trial and the subsequent end-of-Phase 2 meeting with the FDA.
Speaker #3: trial, Dynavax will pay an In addition, after receiving the additional fee of $50 million to Vaxart if Dynavax elects to assume responsibility for continued clinical development of the oral COVID-19 vaccine program.
Speaker #3: Dynavax elects to assume responsibility for the continued development of the oral COVID-19 program, Vaxart may be entitled to receive up to $195 Finally, if million in potential future regulatory milestone payments, million in potential future net sales milestone payments, up to $425 and tiered royalties at rates in the low to sales of our oral COVID-19 vaccines.
Speaker #3: We believe this collaboration is mid-teens on potential future net company. It not only extends our potential of our oral vaccine platform, which could be a major differentiator versus other cash runway, but it speaks to the vaccine delivery methods.
Speaker #3: Later on, James will highlight details of our Phase 2B progress, 2026. We appreciate multiple data sets in Dynavax's view that extremely important for Vaxart as a but we remain on track to announce society as infections, hospitalizations, and even death solutions are in order.
Speaker #3: At persist. And that the new the present time, there are very few deals in the vaccine space, and we appreciate Dynavax's to approval. Partnering with Dynavax will also allow Vaxart to become better positioned for late-stage development on other indications.
Speaker #3: To reiterate, this is a major step forward for the company. We also appreciate that Dynavax shares our view that our transformative approach could potentially revolutionize global public health and improve the distribution and administration of vaccines with their investment and expertise.
Speaker #3: We look assist in moving this project forward forward to sharing updates on our progress and collaboration in the future. Turning to our Norovirus program, as we previously shared, we were pleased to report positive Phase 1 top-line results from our second generation constructs, which demonstrated this vaccine technology produced much stronger antibody responses compared to our first generation constructs.
Speaker #3: Since this positive top-line data update, we have presented at multiple medical conferences highlighting the statistically significant increases in G11 and G24 Norovirus blocking antibodies as well as other analyses from the study, which underscores the potential for protection that provide.
Speaker #3: Sean will share more details of our compelling Norovirus shortly. Norovirus continues data acute gastroenteritis worldwide mortality in countries of all income levels, particularly amongst young children and older adults.
Speaker #3: At an economic cost of more than $10 billion in the United States alone, there remains an urgent need for a safe and effective Norovirus vaccine.
Speaker #3: candidate has first-in-class or best-in-class potential as currently there are no approved causing significant morbidity and vaccines and other products in development do not have the unique profile as well as delivery advantages platform.
Speaker #3: This program continues to dialogue with several interested parties since our last update. While we are committed to securing a partnership, we remain eager to advance. Please understand that these discussions are predicated on the parties' timelines, not just on our funding. We believe that our Norovirus vaccine will anticipate initiating the next clinical trial in Q3.
Speaker #3: ours. As a result, we now programs we look forward to further demonstrating the strength of our oral vaccine program. Now with a partner in Dynavax, we can further advance our COVID-19 program 2026, provided that we receive pending two potentially generate both systemic and robust data readouts in mucosal immunity, our oral 2026.
Speaker #3: With a platform designed to James.
Speaker #3: to transform global public health and revolutionize distribution and administration. I'll now turn the call over to Dr. Cummings for a review of our COVID-19 clinical program.
Speaker #2: Thanks, Steve. And thanks to everyone joining today's call. As Steve has discussed, we've made significant progress with our COVID-19 oral pill vaccine candidate on the business development front, with the signing of an exclusive license agreement with Dynavax.
Speaker #2: We also continue to make important progress in the clinical development of this asset. As we announced in August, we did receive a stop-work order from BARDA on our Phase 2B clinical study comparing our COVID-19 oral pill vaccine to a commercially available mRNA injectable vaccine.
Speaker #2: This order stopped enrollment, but allowed us to continue work associated with the per-protocol follow-up of subjects who had already received a vaccine. In October, we announced that BARDA will continue to provide funding for follow-up for the approximately 5,400 enrolled subjects, consisting of 400 subjects in the Sentinel cohort and approximately 5,000 subjects in the KP2 cohort enrolled in the trial.
Speaker #2: We believe that the trial data from the enrolled participants will provide useful insights and a strong foundation of evidence that could potentially advance our COVID program.
Speaker #2: As a reminder, the primary endpoint of this study is the relative efficacy of our oral pill vaccine compared with the mRNA vaccine for 12 months post-vaccination.
Speaker #2: The trial will measure efficacy for symptomatic and asymptomatic disease, systemic and mucosal immune induction, and adverse events in each cohort. We remain on track to report 12-month top-line data from the 400 participant Sentinel cohort in the first quarter of 2026 and to report 12-month top-line data for all participants in the fourth quarter of 2026.
Speaker #2: In addition to potentially advancing our COVID-19 program, we believe the results of this trial also support our oral pill vaccine platform technology and inform development of our additional pipeline assets.
Speaker #2: I'll turn the call over to Dr. Sean Tucker for an update on those assets.
Speaker #2: Sean. Thank you,
Speaker #3: James. In the third quarter, we presented additional Phase 1 data supporting the potential efficacy of our second generation Norovirus oral pill vaccine candidate at the ninth International Calicivirus Conference.
Speaker #3: The data showed a 25-fold increase in the G2/4 fecal IgA response and a 10-fold increase in the G11 fecal IgA response over baseline, with a high dose of the second generation vaccine candidates after a single tablet administration for each strain.
Speaker #3: The data also showed an 8-fold increase in the G2/4 fecal IgA response and a 7-fold increase in the G11 fecal IgA response over baseline, with a low dose of the second-generation vaccine candidates after a single tablet administration for each strain.
Speaker #3: While the Phase 1 study was not powered to determine superiority by statistical methods, the fecal IgA increases observed with the second generation constructs at the high dose compared favorably to the increases observed with the first generation constructs at the same high dose level.
Speaker #3: As a reminder, the results from the Phase 2 challenge study of our first generation constructs identified fecal IgA as a critical correlate to protection from Norovirus infection.
Speaker #3: The positive fecal IgA results observed with our second generation construct combined with the previously announced serum responses strongly suggest that the second generation constructs induced mus much more robust immunological responses than our first generation constructs.
Speaker #3: We believe this has the potential to translate into improved protection for our second-generation constructs. As previously discussed, this program is ready to advance to the next clinical study, pending a partnership or other funding.
Speaker #3: With the successful completion of a partnership with Dynavax for our COVID-19 program, Norovirus remains a highly attractive opportunity. And we continue to focus on securing resources to advance our second generation Norovirus program.
Speaker #3: We are updating our guidance for the potential timing of the next clinical trial to start in 2026. I'll now hand the call over to Jeroen Grasman for a brief discussion of our financials.
Speaker #3: Jeroen.
Speaker #4: Thank you, Sean. The details of our third quarter 2025 financial results are summarized in today's press release. Revenue for the third quarter of 2025 was $72.4 million.
Speaker #4: Compared to $6.4 million for the third quarter of 2024, revenue in the third quarter of 2025 was primarily from the BARDA contract awarded in June 2024.
Speaker #4: Revenue in the third quarter of 2024 was primarily from a separate BARDA contract awarded in January of 2024. Vaxart ended the third quarter with cash, cash equivalents, and investments of $28.8 million.
Speaker #4: Based on our current plan, which includes proceeds from our license agreement with Dynavax received after the quarter close, Vaxart expects cash runway into the second quarter of 2027.
Speaker #4: Vaxart will continue to remain aggressive in seeking strategic partnerships pursuing other non-diluted funding options and managing our expenses prudently in order to extend our cash runway.
Speaker #4: I will now turn the call back to Steve for closing remarks.
Speaker #5: Thank you, Jeroen. To recap, everyone here at Vaxart is excited about the collaboration agreement with Dynavax for our COVID-19 program. The support from Dynavax and their late-stage expertise will be instrumental as we advance this program.
Speaker #5: Moreover, this partnership further validates our oral vaccine platform, underscoring its potential in transforming global public health. We look forward to sharing multiple data readouts from our COVID Phase 2b trial in 2026.
Speaker #5: Our pipeline of Norovirus flu and HPV assets which our backed by promising preclinical and clinical data demonstrate the broad value of our oral vaccine platform.
Speaker #5: We remain actively engaged with many interested parties about partnership opportunities for each of these programs, and we'll share updates on developments as they become available.
Speaker #5: Before we take your questions, I would like to remind our listeners that we have a scheduled webcasted fireside chat on Tuesday, November 18th at 4:30 p.m.
Speaker #5: Eastern Time. At the fireside chat, we look forward to addressing more of the frequently asked questions we have received from our stockholders. As a reminder, you can submit written questions to ir@vaxart.com.
Speaker #5: We will do our best to answer as many questions as possible at the fireside chat. Since we have the fireside chat next Tuesday, we will not take written questions on the call today.
Speaker #5: Thanks, everyone, for your time today. Operator, you may open up the line for questions.
Speaker #5: questions. Thank you.
Speaker #6: Well, now we can note any question and answer session. If you would like to ask a question, please press star one on your telephone keypad.
Speaker #6: A confirmation tone will indicate your line is on the question queue. You may press star two to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys.
Speaker #6: One moment, please, while we pull for questions. Thank you. Our first question is from Chang Li with Oppenheim.
Speaker #7: Oh, hi. Thanks for taking the questions. And congratulations on the progress and the collaboration with Dynavax. Maybe two questions from us. First, can you maybe talk about why Dynavax decided to reach a deal now instead of maybe waiting for a few months to see the data from the Sentinel cohorts in early '26?
Speaker #7: And also, can you provide some color on the data they saw before maybe reaching the deal? And I have a follow-up question.
Speaker #8: Great. Hi, Chang. Thanks for the question. Yes. So, first of all, we're, of course, very excited to have our partnership with Dynavax. In terms of just what they looked at, right, I think at the high level, first, it's the science and the platform.
Speaker #8: And I think there was a lot of discussions around what the platform can offer, right, and all the things we've talked about in terms of the oral delivery, the mucosal immunity, et cetera.
Speaker #8: And then on top of that, right, I think this was a good time for both companies even before the data came out because of the good fit between the companies, right, as we're really happy to have a proven vaccine company that has been able to take a product through FDA approval as well as through commercialization.
Speaker #8: And I think it just worked out really well from a timing standpoint. And we're delighted to have them on board. In terms of the data that they would have seen, and Jane's can certainly comment on this, we're blinded to the clinical data.
Speaker #8: But as well, in any partnership deal, there's quite a bit of due diligence. And so we're actually pleased that they did take their time to go through the diligence.
Speaker #8: And in the end, felt very comfortable with moving forward with the deal. James, if you want to just comment or reiterate on the fact that certainly in the clinical trial, we're blinded.
Speaker #8: I'll let you comment more on that.
Speaker #9: Thanks, Steve. So from the clinical trial currently ongoing, we are, it's a double-blinded trial. So both ourselves as well as the participants, are unaware of which product they may have received.
Speaker #9: And we continue to collect data on them. The Sentinel cohort will have top-line data available in Q1 of 2026. The larger KP2 cohort, which is approximately 5,000 individuals, will have top-line data available when that study is concluded doing its 12-month follow-up.
Speaker #9: And that would put us in Q4 of 2026. Until that time, because we are double-blinded, we can't comment on further on the study.
Speaker #9: Over. Got it.
Speaker #2: That's helpful. And I guess just another question is with the additional funding, like upfront payments from Dynavax. Can you maybe talk about your thinking about the Norovirus program, whether you can maybe start the Phase 2b trial by yourself?
Speaker #2: If not, what kind of the pipeline priority you are thinking with the additional funding? Thank you.
Speaker #8: Yeah. Thanks, Chang, for the question. I think overall, we're number one excited that we have the validation from a proven vaccine company that our technology has good utilization in the marketplace.
Speaker #8: And certainly for a COVID vaccine candidate, right, they share Dynavax shares in our same view about this still being a good opportunity in the marketplace.
Speaker #8: In terms of our other assets, whether it's HPV, Norovirus, even flu, it's created some opportunities for us to really have ongoing dialogue with potential partners on any of these assets.
Speaker #8: So the priority is still the same, which is including Norovirus, being able to have productive conversations with anyone who is interested in partnering with us.
Speaker #8: On top of that, Sean, who's sitting right here, I think he can also attest to the fact that with the validation of the platform, I think there's also folks who may be interested in providing us their antigen, to our platform.
Speaker #8: Sean, if you want to comment more on that.
Speaker #9: Sure. Yeah. I think that given the strength of our clinical data and, of course, with this recent validation by our friends across the bay at Dynavax, there's been a lot of interest coming up about using some novel antigens with our system.
Speaker #9: And of course, these possible collaborations are still at a very early stage. But we remain committed on the current pipeline. But if something comes along, we're very excited about moving it forward.
Speaker #2: Got it. Thank you so much, and congrats again.
Speaker #1: Our next question is from Thanks. Roger Song with
Speaker #1: Japan.
Speaker #7: Hey,
Speaker #7: team. This is Nabilan for Roger. Thanks for the updates. Just maybe a couple from us. How do you think about this year's COVID season and in comparison with last year?
Speaker #7: And kind of the market potential for something that is, again, oral. How do you also think about your product's strain ability to respond to strain change, as we've seen also not just in COVID, but previously in Norovirus?
Speaker #7: Thank
Speaker #7: you. Great.
Speaker #8: Hi, Nabil. Thanks for the question. Yeah. I'll make some general comments about the market and I think the best person to talk about strains and being able to respond to that is going to be James.
Speaker #8: But I'll just make an additional comment just on our manufacturing. So I think the audience knows that we do our clinical manufacturing right here in South San Francisco.
Speaker #8: And for the COVID trial, we were pretty pleased to be able to produce not only just for the XBB strain, but also for the KP2 strain.
Speaker #8: So, as a company, we think we are pretty versatile in being able to manufacture something for a strain in a very timely manner. I think you've seen, as well, just to your first question around the COVID marketplace, right?
Speaker #8: And it's still a sizable market. Certainly, there are less folks who are taking the COVID shots now. It could be attributed to what's happening in the press.
Speaker #8: It could be attributed to their perceived side effects. It could be just perceived on the fact that it's a bit of a hassle to schedule an appointment, go to the pharmacy, get the shot.
Speaker #8: And from our standpoint, we offer a lot of advantages as well as alternatives to that. So I think from our standpoint and Dynavax certainly evaluated as well that there is still a good market opportunity as it relates to COVID.
Speaker #8: I'll turn it over to James if you want to comment a bit just on strains and so
Speaker #8: forth. Thanks,
Speaker #9: Steve. And thanks for the question. So I think two things. One, in terms of strain changes, what we've shown earlier in our development of this product is that we have the ability for cross-reactivity, not just for the strain of interest, the strain that was developed for this product, but also across newly developing strains.
Speaker #9: And so the benefit of this one of the benefits of this protocol is that we're looking at efficacy over and up to 12-month period.
Speaker #9: And during that time, not only taking a look at was someone ill, or infected with the virus, and/or symptomatically ill, but also taking a look at what the potential strains may be.
Speaker #9: As we know, the coronaviruses do have an ability to adapt and to shift or strain change. And so we would expect over the course of a 12-month period that we'll see more than likely one strain circulating certainly in the United States, but really across the globe.
Speaker #9: And so that's some of the data that we'll be taking a look at as part of this
Speaker #9: study. Thank
Speaker #9: study. Thank One other thing you.
Speaker #1: That's helpful.
Speaker #9: I one other thing I'd like to add on, and this is one of the again, one of the key things about that we demonstrated in a nice animal model is we showed that our vaccine in Bruce and these producing these mucosal responses, it could impact the ability of the virus to be transmitted to others.
Speaker #9: So it may have a better overall health benefit and certainly this kind of this platform makes it much because it's oral too, much more differentiated than other things that are out there.
Speaker #1: Thank you, team. Thank you. This concludes our question and answer session. We want to thank you again for your participation today. You may disconnect your lines.
