Earnings Call Analysis
Q4-2023 Analysis
Dynavax Technologies Corp
The company is making strides in advancing its clinical pipeline. They submitted an investigational new drug application (IND) for their Phase I/II trial of Z-1018, expected to start in the first half of 2024 with top line immunogenicity data anticipated in the latter half of 2024. For their Tdap vaccine, they plan to proceed to a human challenge study later this year after positive FDA feedback and promising results from previous studies. The company's collaboration with the Department of Defense on a plague vaccine is moving forward, with Phase II trial data expected by the end of 2024. Additionally, they are awaiting FDA action on extending the use of HEPLISAV-B for adults on hemodialysis, which could potentially open up a new market segment for them in 2024.
The company has reported a robust financial performance with HEPLISAV-B's net product revenue growing by 69% to $213 million in 2023, aided by a gross margin of approximately 76%. This positive momentum is expected to continue into 2024 with an estimated gross margin of around 80%. Other revenue, mainly from the plague vaccine program, also increased to $19 million in 2023, indicative of the progress in Phase II clinical contracts.
Research and development expenses rose to $55 million in 2023, reflecting the company's dedication to advancing its clinical and preclinical development programs. A rise in selling, general and administrative expenses to $153 million signals intensified commercial investments to expand HEPLISAV-B's market share and tap into new opportunities. Despite these investments leading to a net loss of $6.4 million in 2023, the company maintains a strong cash position of $742 million, estimated to be sufficient for their current pipeline and business requirements without needing external capital.
For the full year 2024, the company projects HEPLISAV-B net product revenue to be in the range of $265 million to $280 million, including a modest contribution from international sales. They anticipate the gross margin for HEPLISAV-B to remain high at around 80%, with research and development expenses expected to be between $60 million and $75 million, and selling, general and administrative expenses between $160 million and $180 million. Importantly, the company is poised to be cash flow positive by the end of 2024, reflecting a focused capital allocation strategy that aims to drive revenue growth and advance research programs.
The management remains committed to evaluating strategic opportunities to diversify its commercial and clinical portfolio. Investment priorities will revolve around driving growth for HEPLISAV-B, advancing internal clinical-stage assets, and considering other methods to generate shareholder value. Outsourcing of capital to partnerships or returning capital to shareholders will depend on circumstances and be approached judiciously.
The company asserts that macroeconomic factors and market dynamics for adult vaccination, particularly the HEPLISAV-B market, are not significantly impacted by broader economic issues thanks to strong reimbursement coverage under the Affordable Care Act. They anticipate continued growth in this sector despite general economic trends. Regarding their developmental programs like shingles vaccines, specific launch timings are yet to be determined, as these involve multi-year clinical development processes. The company prefers to follow a traditional vaccine development pathway without speculating on precise market entry dates.

Good day, ladies and gentlemen, and welcome to the Dynavax Technologies Fourth Quarter and Full Year 2023 Financial Results Conference Call. [Operator Instructions]
I would now like to turn the call over to Paul Cox, Vice President, Investor Relations and Corporate Communications. You may begin.
Thank you for participating in today's call. Joining me from Dynavax are Ryan Spencer, Chief Executive Officer; Donn Casale, Chief Commercial Officer; Rob Janssen, Chief Medical Officer; and Kelly MacDonald, Chief Financial Officer.
Earlier today, Dynavax released financial results for the fourth quarter and full year ended December 31, 2023. Copies of the press release and a supplementary slide presentation are available on Dynavax's website.
Before we begin, I advise you that we will be making forward-looking statements today based on our current expectations and beliefs, including, but not limited to, potential market sizes, market segmentation, effective marketing efforts, future expected market share and related growth rates and related ACIP recommendation impact on each financial guidance and trends, including revenue, profitability, cash flow and sufficiency of current capitalization, timing and results of FDA submissions, clinical trial starts and data readouts and and potential future uses of or demand for our CpG 1018 adjuvant.
These statements involve risks and uncertainties, and our actual results may differ materially. These risks are summarized in today's press release and detailed in the Risk Factors section of our SEC filings, including today's annual report on Form 10-K. Our forward-looking statements speak as of today and we undertake no obligation to update such statements.
And with that, I will now turn the call over to Ryan.
Thanks, Paul. good afternoon, everyone, and thank you for taking the time to join us to review Dynavax's results for 2023. 2023 was characterized by a record revenue growth for EPL delivering 69% growth year-over-year and becoming the market share leader in the 2 largest growth segments, which are retail pharmacies and integrated delivery networks, making HEPLISAV is the leading vaccine in the U.S. adult hepatitis B vaccine market. We expect 2024 to be an important year in building our vaccine portfolio of best-in-class products, including further growing HEPLISAV-B brand and advancing our pipeline programs into clinical trial initiations and data readouts. For HEPLISAV-B, we are again forecasting continued growth with net product revenue in the range of $265 million to $280 million for the year. In a few minutes, Donn will provide some additional commentary on how the U.S. hepatitis B vaccine market is evolving due to an active winter respiratory disease season and why we continue to be very confident in another year of growth for the brand and in the long-term prospects for HEPLISAV-B in a vaccine market with one of the largest total addressable populations in the United States.
For our development pipeline, we expect to achieve important milestones in the coming months, including our PDUFA action date for the HEPLISAV-B sBLA for hemodialysis expected in May. Clearing our Shingles IND currently being reviewed by FDA to begin our Phase I/II trial, advancing our TdaP program and delivering Phase II clinical and nonhuman primate challenge study data for our play program under collaboration with the U.S. Department of Defense.
Importantly, our strong financial position of $742 million of cash provides us with the optionality to continue to build value across our business, such as through incremental investments to drive the HEPLISAV-B market opportunity, continuing to advance R&D efforts, and pursuing new opportunities to accelerate our growth. As we've discussed previously, we continue to evaluate strategic opportunities to further diversify our clinical and commercial product portfolio.
We remain committed to disciplined capital allocation to generate significant value and accelerate growth. We look forward to providing updates on these efforts in the future.
I'll now turn the call over to Donnto provide more details on the HEPLISAV-B results and our guidance looking forward.
Thank you, Ryan. In 2022, we achieved record net product sales and market share, establishing HEPLISAV-B as the leading adult hepatitis vaccine in the U.S. market. Additionally, we drove significant hepatitis B market growth by effectively pulling through the ACIP universal recommendation. Our success in 2023 reaffirms our confidence in a sizable market opportunity and long-term revenue growth potential for HEPLISAV-B. The U.S. adult hepatitis market continued to grow in 2023 following the ACIP universal recommendation for hepatis B vaccination which now represents one of the largest vaccine market opportunities for adults. We believe this recommendation will continue to be a significant catalyst for growth and estimate the hepatitis B vaccine market update for HEPLISAV grew to approximately $525 million in 2023 on a clear path to approximately $800 million by 2027, with HEPLISAV-B achieving a majority market share by that time.
During the fourth quarter, we continue to see indicators of U.S. market expansion from the ACIP universal recommendation. Despite softness in the market related to reduced wellness visits, and an increased focus by health care providers on respiratory disease vaccines, including typical flu campaign and the launches of RSV and endemic COVID-19 vaccine. HEPLISAV-B continues to increase its total U.S. market share, achieving 42% at the end of 2023 compared to 35% at the end of 2022. Net product revenue in 2023 grew 69% year-over-year. This sales growth continues to be driven by HEPLISAV-B strong performance in 2 critical segments: Retail pharmacy and integrated delivery networks or IDN. We continue to focus our sales and marketing efforts on the retail pharmacy and IDN segments as we expect to see most of the anticipated market growth from the ACIP inversal recommendation in these segments. Estimating both will grow to represent over 60% of the total hepatitis B market by 2027. HEPLISAV-B is now the market share leader in both of these key segments. For IDNs, at the end of the year, HEPLISAV-B market share increased to approximately 56% compared to approximately 47% at the end of 2022.
We are focused on working with large health systems at the C-suite and clinic level to pull through ongoing adoption of the universal recommendation. Customers continue to respond positively to the ACIP change and recognize the need to adopt and implement the recommendation. Full year hepatitis B vaccine market growth in the IDN segment was 41%. In the Retail Pharmacy segment, we have made significant progress in several large national chains, making HEPLISAV-B the preferred adult hepatitis B vaccine. At the end of the year, HEPLISAV achieved approximately 58% market share in the Retail Pharmacy segment compared to approximately 42% at the end of 2022.
We continue to see and expect significant growth from the Retail Pharmacy segment. Full year hepatitis B vaccine market growth was 78%. As Ryan noted, we are providing full year 2024 net product revenue guidance for HEPLISAV-B to be in the range of $265 million to $280 million. This guidance reflects our momentum in the market while factoring in the evolving market landscape and emerging quarterly patterns of nonrespiratory vaccination that we expect to see in 2024. Based on feedback from customers, cough, cold and flu season has extended much further into January than expected, reducing the number of wellness visits and vaccination opportunities.
Due to the softness in January, we anticipate little to no growth in the hepatitis B vaccine market for Q1 as compared to Q4 of 2023. Encouragingly, we expect the market to strengthen for the remainder of Q1 into Q2 as the focus of health care providers and retail pharmacy shifted back to prioritizing nonrespiratory vaccines. As a result, we expect to recognize up to 60% of our full year revenue range in the second and third quarters, with typical Q4 seasonality expected. We are extremely confident in the long-term expansion of the U.S. hepatitis B vaccine market and forecast annual market growth of approximately 10% to 15% over the next several years, with HEPLISAV-B gaining meaningful increases in total market share over that time.
In summary, we had a tremendous 2023, reaffirming our confidence that HEPLISAV-B will strengthen its position as a clear market leader in the expanding hepatitis B vaccine market. We are very proud of our commercial team's execution and encouraged by the progress and momentum for HEPLISAV-B establishing a majority market share in the key segments of retail pharmacy and IDN.
I will now turn the call over to Rob to take you through our clinical pipeline.
Thank you, Donn. As a reminder, in our development pipeline, we're advancing innovative and diversified vaccines that leverage our CpG 1018 adjuvant with proven antigens. We also continue to identify new opportunities to leverage our CpG 1018 adjuvant through multiple innovative preclinical and discovery efforts with leading collaborators. Starting with our shingles vaccine program, Z-1018. Currently, there's a successful licensed vaccine on the market, but we believe there's an opportunity to develop an improved vaccine given the challenging tolerability profile of the current market-leading product.
One of the unique advantages we believe of our CpG 1018 adjuvant is its safety and tolerability profile, combined with its ability to induce strong CD4 positive T cell responses, which we believe are critical to preventing the reactivation of disaster virus. Results from our Phase I trial support the continued development of Z-1018 as they demonstrate the opportunity to develop a shingles vaccine with an improved tolerability profile and comparable efficacy. Late last year, we received Type B meeting feedback from the FDA on the Z-1018 program, which we believe is supportive of our proposed clinical development plan that includes a pivotal placebo-controlled efficacy study.
We recently submitted an investigational new drug application or IND to the U.S. FDA to support the initiation of a Phase I/II trial of Z-1018 in the first half of 2024. We will be evaluating escalating doses of our GE protein, our selected dose of CpG 1018 with or without alum and different vaccination schedules. We plan to enroll approximately 400 subjects and anticipate top line immunogenicity data in the second half of 2024.
Now turning next to our TdaP1018 program. This is an investigational vaccine candidate intended for active booster immunization against tetanus, diphtheria and pertussis or Tdap. Current Tdap vaccines have limitations, including waning effectiveness. We believe there's an opportunity to improve the duration of protection using our CpG 1018 adjuvant to generate a TH1-biased immune response. We've completed both the Phase I clinical trial in adults and adolescents as well as a pertussis challenge study in nonhuman primates. We recently received Type B pre-IND meeting feedback from the FDA on the Tdap1018 clinical development and regulatory pathways. Together, results from our Phase I study our nonhuman primate study and the feedback from FDA all support proceeding to a human challenge study this year.
We plan to submit an IND to the U.S. FDA to support the initiation of this Phase II human challenge study of Tdap1018 in the second half of the year, upon completion of the independent study being conducted by the Canadian Center for vaccinology to establish the human challenge dose, which we will utilize in our Phase II study.
Moving on to the plague program. This is a collaboration with and funded by the U.S. Department of Defense. We are conducting a Phase II trial evaluating the immunogenicity, safety and tolerability of a 2-dose plague vaccine candidate that is adjuvanted with CpG 1018. The CpG 1018 adjuvanted vaccine candidates mechanism of action has the potential to speed up time to protection with fewer doses compared to the 3-dose alum adjuvanted vaccine previously developed by the Department of Defense.
We're currently conducting a randomized active controlled Phase II clinical trial evaluating immunogenicity, safety and tolerability of the plague vaccine candidate. And in parallel, we're conducting a non-human prime challenge study. We expect top line data from both of these studies by the end of 2024, and these data will inform next steps for the program.
Now in addition to these development programs, we've also filed a supplemental BLA for HEPLISAV-B vaccination of adults on hemodialysis, which the FDA has accepted with a PDUFA action date in May of 2024. If approved, this would allow us to promote a 4-dose regimen of HEPLISAV-B to the dialysis population. We look forward to continuing to make progress across these programs in the months ahead. and we're excited to initiate the next clinical trial for both our shingles and Tdap programs in the coming year.
I'll now turn the call over to Kelly to review our financial results.
Thank you, Rob. I'm pleased to report another quarter and full year of strong financial performance. I'll review the key financial results for 2023 as well as our financial guidance for 2024. Please note that all financial comparisons are versus the prior year period, unless otherwise noted. Please also refer to our press release and Form 10-K for more detailed financial information. Starting with HEPLISAV-B, net product revenue grew 69% year-over-year to $213 million in 2023, another record year for the franchise. We are also pleased with our continued trend in the margin profile for HEPLISAV-B and with gross margin of approximately 76% in 2023, consistent with our guidance of mid-70s percentage for the full year and significant improvement compared to about 68% in the prior year.
Looking forward, we expect gross margins of approximately 80% for the full year 2024, which is consistent with our long-term expectations of margin profile for this brand. Other revenue was $19 million in 2023 compared to $9 million in the prior year period, representing revenue related to the play vaccine program in collaboration with and funded by the U.S. Department of Defense. The increase was primarily driven by the advancement into a nonhuman primate challenge study as well as continued progress throughout our Phase II clinical contracts with the vaccine candidates.
Turning to our expenses. Research and development expenses for 2023 increased to $55 million compared to $47 million for the prior year period, with the increases reflecting continued advancement in our clinical and preclinical development programs. Selling, general and administrative expenses for 2023 were $153 million compared to $131 million for the prior year period, with the increase primarily driven by higher compensation and related personnel costs and an overall increase in targeted commercial investments designed to drive HEPLISAV-B market share and maximize the opportunities presented by the ACIP's universal recommendation. These results generated GAAP net loss of $6.4 million in 2023 compared to a GAAP net income of $293 million during 2022.
Moving to the balance sheet. We ended the year with cash, cash equivalents and marketable securities of approximately $742 million, which we believe is sufficient to progress our current pipeline assets and support our organic base business without the need to raise additional capital.
Turning towards 2024, we are providing the following full year financial guidance. HEPLISAV-B net product revenue is expected to be between approximately $265 million and $280 million, including approximately $3 million in ex U.S. sales through our commercialization agreement with Bavarian Nordic and Germany. We expect HEPLISAV-B gross margin of approximately 80% for full year 2024 and -- we expect R&D expenses to be between approximately $60 million and $75 million. We expect SG&A expenses to be between approximately $160 million and $180 million and we also expect to be cash flow positive for the full year ended December 31, 2024, reflecting our continued discipline towards allocating capital to drive top line revenue growth while thoughtfully advancing our research programs.
In closing, we believe that with our strong financial profile, we are well positioned to drive sustainable growth in our core HEPLISAV-B business, capture a majority market share and lead the expansion of the adult hepatitis B vaccine market. We look forward to progressing our R&D portfolio of vaccine candidates, while continuing to be extremely thoughtful in how we allocate our capital to accelerate growth and build beyond our current base business. We are excited about our progress to date, and we look forward to continuing to deliver on our goals for this year and beyond. Thank you, everyone, for your attention today.
Operator, we would now like to open the Q&A portion of today's call.
[Operator Instructions] Our first question comes from the line of Matthew Phipps with William Blair.
Congrats on a great '23. Last year, I just wanted to visit last year, and you initially gave guidance of that was lower $165, $185, something like that. And throughout the year, you raised it 20%, over 20% with subsequent updates. Just -- what were the factors you think that drove greater-than-expected sales from your initial point last year? Was it greater growth of the total market or market share gains -- just kind of wondering what factors might influence where your guidance goes from today in 2024?
Matt, thanks for the question. I think we have to remember, 2023 was the first year -- first full year coming out of both reconciliation of pandemic demand as well as the ACIP universal recommendation. So one of the things we said -- I think we were pretty clear about as I recall from our prior earnings calls is that the market growth in '23 outpaced our original expectations when we originally provided guidance earlier in the year. So we also had fairly successful growth in market share throughout the year. And so those 2 factors dominated by better market growth than originally projected.
Yes. Okay. And does your guidance for this year include any contribution from the dialysis segment?
Yes. I mean, we don't really provide guidance segment by segment. So we want to sit through that. Our guidance for the year takes into account a lot of different puts and takes on how the year can evolve, so we're not going to be able to comment on one specific segment.
Our next question comes from the line of Jonathan Miller with Evercore ISI.
Also congrats on '23 growth. I wanted to drill down a little bit into that comment you made on little growth in the hep B market in Q1. And do you still have an opportunity to grow share in Q1? To what extent is share growth tied to market -- overall market expansion, I guess?
And then secondly, what are your expectations on regulatory requirements for plague beyond the Phase II and the NHP studies this year. What do you expect from regulators? And what do you expect from DoD?
Why don't we take the thanks, John. Thank you for the questions. I'm going to have Donn tap your first question, and I'll pick up the second one.
Jonathan, regaining share, actually, we're excited about our ability to continue to take market share. this quarter is no different. It's one of the things to be consistent around is the ability to take market share. So we like our position and our ability to take market share in the first quarter, even with the market being where it is.
And then the second question regarding the plague plan, the regulatory plan, I think it's important to know the reason we're doing the nonhuman primate study is because that's a key part of the regulatory path for a product like to [indiscernible] the animal and so what we don't know yet is a specific path on whether or not there will be additional work required to satisfy the filing needed under that pathway with the agency. Rob, I don't know if you have any other comments you want to make around plague.
No, I think you covered it. I don't think at this point, we know what would be required, say, for an EUA versus a full approval, not at this point.
A little bit -- the data will also be an important aspect of that. So we really need to see that data before we can confirm the pathway.
And then just one more on gross margin. you said 80% plus for HEPLISAV, but how does the potential DoD collaboration revenue and other revenue line tie into that, could total gross margin, overall gross margin still be in the mid-80s higher?
So the guidance -- so thanks for the question. The guidance is approximately 80% for the full year for HEPLISAV. Our other revenue line item is predominantly our play contract reimbursement which doesn't carry significant margin -- or sorry, significant cost of goods at loss doesn't carry any cost of goods, but also, yes, to the extent we continue recognizing which we expect to continue recognizing other revenues through that contract, our total company gross margins would be slightly higher than that 80%.
Our next question comes from the line of Paul Choi with Goldman Sachs.
Congrats on the strong finish to '23 from us as well. I want to maybe just ask on your thinking with regard to the guidance. And as you think about the macroeconomic environment we're in and people's price sensitivity and sensitivity in terms of thinking about health care spending versus the high inflation environment. How do you think about maybe sort of the puts and takes of that in terms of the demand growth over the course of the year? And would that -- is that something you're thinking about in terms of in your guidance? And then I had a follow-up on capital allocation.
Thanks for the question, Paul. -- our guidance, obviously, is very specific to the market dynamics for adult vaccination and we don't see some of those macro factors having a big impact here at all on the tie hepB market. It's a very -- the reimbursement for that segment is incredibly well. There's a first dollar coverage required under the Affordable Care Act. So we think we're in a good position as it relates to some of those macro factors to continue to grow the vaccine market through 2024 and beyond.
Okay. And then as a follow-up, I know you and the team have talked about BD and/or partnering here. But I guess as you sort of survey the landscape and sort of where potential bid-ask spreads or perhaps risk appetites are. I guess if is partnership where BD opportunities don't materialize in the, let's say, in the next 12 to 18 months, how would you think about then rank ordering your capital allocation outside of investing in the HEPLISAV business?
Yes. No, I think I appreciate you highlighting the fact that there's there's a lot of flexibility in identifying the right asset for Dynavax. So Kelly, why don't you provide some commentary on our overall capital allocation strategy?
Sure. So our exceptional commercial execution for HEPLISAV-B along with our adjuvant supply business, of course, has created this strengthening of our financial profile. We certainly believe the strong position will help us drive further growth including, first and foremost, looking for opportunities to invest in driving growth in HEPLISAV-B as well as advancing our organic clinical-stage assets as well as our preclinical portfolio. As we reflect on opportunities outside of that, to Ryan's comments around corporate development, we do continue to evaluate strategic opportunities to diversify our commercial and clinical product portfolio. And then beyond that, certainly, we do evaluate and consider other opportunities to either return capital to shareholders if and when appropriate, as well as other ways to generate value for our shareholders. something that's sort of the right quarter where we stand today.
Our next question. next question comes from the line of Ernesto Rodriguez Dumont with Cowen.
Congrats on a great year. I have a question about the effects that you described from the longer-than-expected respiratory vaccine season and the Q4 seasonality, are those effects over come during Q4 and Q3 -- or do you have to like internally adjust your estimates for 2024 based on that?
And then second question regarding the gross margins. What's driving the improvement in gross margin, you see economies of scale and lower cost? Or are you expecting to have more pricing power?
Yes, I'll take the first one and Kelly, if you can handle the second one. As far as -- Ernie, thank you for the question. I interpreted the first part of the question to say what we see in Q1 impact how we think about the rest of the year, does it change how we update our guidance. I mean, ultimately, we we only drive 1 guidance number when we're ready to provide it. So I don't -- it's kind of hard to think about how individual factors impacted. But like we said in the call script, -- we know that Q2 and Q3 will continue to be the strongest quarters of the year. Our continued interactions with our customers are incredibly positive. So we're very excited to get out of the respiratory season and the respiratory vaccine season and start working with our customers on the nonrespiratory part of the year and to really drive growth in this market. Kelly, can you handle the gross margin?
Sure. On gross margins for HEPLISAV-B, these margin improvements have been driven by a couple of things, but namely just decreasing our per unit manufacturing costs, we made a number of investments in our antigen manufacturing facility in Germany. I really proud of the way that we've been able to pull through those improving yields over time to realize sort of an estimate of approximately 80% gross margin for 2024. To reiterate, a point that I made in the prepared remarks, we do expect this 80% gross margin range to represent levels that are consistent with our long-term expectations for this brand.
Our next question comes from the line of Edward White with H.C. Wainright.
This is Steve on for Ed. A few questions. for the shingles vaccine, do you have an expected timing to market?
We haven't commented on the long-term specificity of our launch. Obviously, it's full clinical development program, so it takes multiple years to move forward. We have commented on the Phase I/II trial and the expectation of that data in 2025. and then we'll have to roll forward from there, Stephen, on expectations for moving into the next study, citing the study looking at enrollment dynamics to figure out exactly when that would be able to read out. So it's a little premature for us to predict the specific timing of filing and ultimate approval. But we have provided general commentary that it's traditional vaccine development pathway. And there's good reference points for prior trials conducting in the space to get a sense of the time lines taken for those studies.
Okay. And so there were no adjuvant sales this year, right?
No adjuvant sales this year. We don't contemplate additional adjuvant sales for our COVID partnerships in 2024 at this time.
Okay. And what about in 2025 and going forward?
It's unclear. -- depend on how the market demand, how the markets evolve and how are individual collaborators products are utilized and the efforts they put behind keeping up with the shifting landscape, including strain management. So obviously, we'll be supportive of our partners and their initiatives, we believe COVID vaccination will continue globally for the years to come, and it's an important product in the marketplace. And so we will be there to support them as needed.
Our next question comes from the line of Roy Cannon with Citizens JMP.
Just a couple of quick ones on the plague. Are you going to announce the results of the not human challenge trial in the Phase II at the same time later this year. Can you remind me, are you making any cell-mediated immunity assessments in the plague Phase II? And do you think those might be important. Any thoughts on that?
I'll take the first one, and then I'll ask Rob to follow up on the second. One of the things you got to realize with the study with the -- by the DoD is this is data that is -- we have to work with our DoD partners on the release data release. And so that has not been clarified yet on exactly what the opportunity will be to share the data in what forum for either trial. So we need to basically complete these trials for [indiscernible] and we'll be able to make some top line comments like we have in the past. -- but we don't have a data release plan across both trials together, but we will work to be able to provide as much clarity on how the program is progressing in partnership with DoD. The primary endpoint is antibodies that Rob, please treat any other commentary you have around cell media immunity in the plague program.
Yes. The primary endpoint is looking at to antibodies because that's been -- that's what DoD has used previously as they've developed this vaccine particularly with respect to looking at antibodies in nonhuman primates and then applying those to humans. We aren't looking at cell media immune or T cells in our -- in this Phase II study.
Thank you. At this time, I'd like to hand the conference back over to Mr. Ryan Spencer for closing remarks.
Thank you, operator, and thank you all for joining us today. We appreciate your interest in Dynavax. We're excited about our recent accomplishments and the strength of our position overall. We look forward to updating you on our progress focused on protecting the world against infectious diseases. Operator, you may end the call.
Ladies and gentlemen, thank you for joining us today. This concludes today's conference call. You may now disconnect. Everyone, have a wonderful day.
