Thank you for joining us. Welcome to Invivyd’s First Quarter 2025 Earnings Conference Call. All participants are currently in a listen-only mode. Following the presentation, there will be a question-and-answer session. I will now turn the call over to Katie Falzone, Senior Vice President of Finance. Please proceed.

Thank you, Operator. A short while ago, we issued a press release announcing our Q1 2025 financial results and business highlights. That press release and the slides that are being used on today’s webcast can be found in the Investor section of the Invivyd website under the Press Release and Events and Presentation sections, respectively. Today’s discussion will be led by Marc Elia, Chairman of the Invivyd Board of Directors. He is joined by Tim Lee, Chief Commercial Officer; Bill Duke, Chief Financial Officer; Dr. Robert Allen, Chief Scientific Officer; and Dr. Mark Wingertzahn, Senior Vice President of Clinical Development. During today’s discussion, we will be making forward-looking statements concerning, among other things, our corporate and commercial strategy, our research and development activities, our regulatory plans, certain financial expectations, our future prospects and other statements that are not historical facts. These forward-looking statements are covered within the meaning of the Private Securities Litigation Reform Act, and are subject to various risks, assumptions, and uncertainties that may change over time and cause our actual results to differ materially from those expressed or implied today. These forward-looking statements speak only as of the date of this call, and Invivyd assumes no duty to update such statements. Additional information on the risk factors that could affect Invivyd’s business can be found in our filings made with the U.S. Securities and Exchange Commission, including our most recent Form 10-K and 10-Q, which are also available on our website. I will now turn the call over to Marc.

Good morning and thank you all for joining us. Turning to Slide 4, the first quarter and our early second quarter has been a very busy and productive time marked by transition. Our commercial organization is now wholly internalized, new in the field and reflects an intentional bet by this management team that our new internal team will drive broader adoption of PEMGARDA with associated commercial results. While it is early, our leading indicators are promising and we remain targeting near-term breakeven with continued revenue growth and operating expense management. Scientifically, we’re very pleased with what we see in the evolutionary journey of SARS-CoV-2 relative to the epitope we are exploiting with pemivibart, and as of now, we see no obstacle to long-term growth in our commercial PEMGARDA business. We have secured access to additional non-dilutive capital to grow if certain conditions and milestones are met, and we are expanding our pipeline to multiple disease areas in which we believe our scientific approach can add value to patients in need. Specifically, we have added discovery programs against new viral targets with the potential for identifying best-in-class medicines for diseases outside of COVID-19. Our previous work in influenza continues at a low intensity, but bird flu with pandemic potential has not meaningfully emerged, and in the very recent short time, we have actually seen more U.S. deaths from measles outbreaks than we have seen from avian influenza over the past year or so. At this point, it is reasonable to expect that trend to continue and our focus has shifted accordingly toward early measles discovery. Last year, we initiated a new discovery program for an RSV monoclonal antibody that Robbie Allen, our CSO, will describe in a bit more detail. RSV presents a very clear, high-value competitive landscape and some molecular properties we believe we can target to generate a potential best-in-class monoclonal antibody with blockbuster commercial potential. As we grow and expand our COVID franchise, we will accordingly want to make targeted, financially responsible investments in discovery that can yield drugs we can capitalize for development, either in concert with the equity markets or with potential strategic partners. There has been no shortage of interest in our work from potential partners, particularly those with a vaccine footprint. It’s important to note that our corporate goals, including targeting near-term breakeven, are audacious by design and reflective of our integrated strategic and operational choices. In the big picture, we want to create as much medical value for patients and society as fast as possible, and then we want to translate that value into per share shareholder value as efficiently as possible. In an easy biotech financing environment characterized by low interest rates and long return horizons with blue skies for investors, it is much easier for companies to raise large quantities of dilutive equity that may enable a mediocre or far-fetched biological premise to survive to the next catalyst. But such a business strategy rarely translates into long-term per share compounding of shareholder value. We are taking the opposite approach and trying to be highly disciplined with our expenditures and capital base to the maximum extent, not just because these days the biotech investing backdrop and equity cost of capital has been tougher. We’ve been taking our approach because we see full operational proof-of-concept in our ability to make medicines rapidly and efficiently, and we wish to exploit that advantage, which we see as unique in the industry as we grow our business so that our shareholders can benefit accordingly. Turning to Slide 5, in the bigger social picture, it is important to note that our fundamental corporate strategy reflects a great many macro-level realities that have also undergone transition, specifically a U.S. election result and new public health leadership focused on chronic disease who are moving in directions on multiple fronts that comport well with our business strategy. A quick reminder, Invivyd was started based on a simple reality, that SARS-CoV-2 was a unique virus designed to prey on a distinctly vulnerable human population. It was clear early that vaccines for COVID-19 disease would work over the short-term, but that waning responses would be problematic for every person, especially for immunocompromised persons. And on top of that, immune-evasive Omicron viruses have added another headwind, as has the growing underlying burden of long COVID. More, given the handling of COVID-19 vaccine policies, there is a regrettable secular shift underway with respect to American attitudes toward vaccination as a whole. Reviewing the last year’s events concerning COVID-19 vaccine, such a shift is indeed regrettable, but perhaps not surprising. Monoclonal antibodies can be designed to overcome challenges with vaccination. After all, we are all born immunocompromised and preloaded with a suite of non-self-monoclonal antibodies from our mothers. And yet, in the pursuit of freedom from the burden of SARS-CoV-2, our regulatory and public health complex for four years was single-mindedly focused on exposing humans serially and broadly to the spike protein, largely in mRNA form, in an effort to get us our protective antibodies the hard way. Rather than, as mother nature might suggest, providing mechanisms for humans to access additional antibody support so that humans don’t need to choose between dangerous infections and increasingly debatable vaccination. Unique in the industry, Invivyd has now fully developed, through multiple placebo-controlled RCTs, two monoclonal antibodies against SARS-CoV-2: adintrevimab against ancestral viruses like Delta, and now pemivibart against contemporary immune-evasive Omicron viruses. More, in our recent CANOPY Phase 3 clinical study assessing safety, immunobridging, and exploratory clinical efficacy analyses, we are reporting clinical results from a modern American population, specifically a population that has preexisting immune experience or seropositivity in both study and placebo arms. To some observers of the vaccine industry, conducting such studies is undoable or unthinkable. And yet, to us and others in the monoclonal antibody business, those studies are business as usual. You will see elements of our recent Citizen Petition to the U.S. FDA that focuses on these issues because to us, there is clearly within reach a mechanism to scale access to monoclonal antibodies if and when regulators so choose. As you will see later in this morning’s call, we have multiple parallel conversations with public health authorities designed to expand the consequences of our discovery and development work. With that, I’ll turn the call over to Tim Lee to discuss our commercial progress in the quarter.

Thank you, Marc, and good morning all. Turning to Slide 6, the first quarter cemented our transition from a contracted, largely outsourced model designed to hit a short seasonal window to a best-in-class commercial footprint to drive consistent growth via an in-house team. We did not have a fourth quarter call, so it’s been six months since I’ve had the opportunity to speak with the broad investor community. And it’s worth sharing a few general observations from the fall and winter before we walk through key indicators. Marc and the team asked me to create a best-in-class commercial effort to put behind PEMGARDA and our future molecules. I’m pleased with what we’ve done so far, but in many ways, we are just getting started. First, we spent an enormous amount of time with healthcare providers and health systems simply re-educating them on the existence of monoclonal antibodies as an alternative therapy available today. What began as a commercial interest, largely driven by those who knew and anticipated PEMGARDA, we’re now beginning to see institutional orders that are just beginning to reflect the underlying medical needs. Protocols, pathways, real-world experience and word of mouth in the clinical community are still in the early innings, and we expect real growth to follow as this familiarity rises. Second, healthcare providers began with real skepticism on the ability of PEMGARDA to navigate virus evolution, particularly following the FDA’s misguided and harmful insertion of inaccurate third-party virology data into the PEMGARDA fact sheet last fall. The combination of our communication of the underlying science, along with the empirical reality of the attractive continuing activity is now gaining notice and belief. Third, the understanding of COVID-19 in the community has undergone a notable evolution. Most healthcare providers are now moving beyond the pandemic era concept of an acute respiratory syndrome, the SARS part of SARS-CoV-2, and now see acute infection and corresponding respiratory disease as part of a much broader, more insidious long-term health challenge. We are, and we believe now, on the forefront of educating these clinicians on why patients who are battling cancer, navigating transplant or who lack sufficient immune cells to mount a response to vaccination need a protective option. The untapped market potential ahead of us remains numerically vast. As we execute in our new posture, we expect to see a meaningful acceleration in product growth. Now I can get into the specifics of execution. On Slide 7, you see here the top-level metrics accompanied by three of the structural elements we have installed at Invivyd. We have moved to a focused, trained, in-house team, ending our relationship with contract representatives. We have established and built a culture of accountability and measurement. We have substantially refined our messaging and believe that we are recognized as leaders in the COVID-19 field by healthcare providers and institutions broadly. All of these elements are the keys to each successful launch in the Pharmaceutical Growth Initiator Nation over my career. We’re also beginning to make progress around numerous fronts, including contracting. While not contemplated in the early launch, we are receiving scaled interest from organizations who wish to derive value from commitments to our large ordering and are pleased to be working with them. We’re seeing ourselves placed in pathways, protocols and guidelines nationally, leading to a deeper understanding of PEMGARDA. Turning to Slide 8, Slide 8 shows the continued steady growth in our commercial reach. While Q1 revenues dipped from Q4, we believe much of that is attributable to the lack of feet on the street. In January and February, as we deployed, hired our new sales team, encouragingly, we’ve seen strong revenues thus far in Q2, including, for example, our biggest ever commercial day and biggest ever commercial week. Day-by-day, the highs are getting higher and the lows are getting higher as well. This is the hallmark of ongoing growth. Turning to Slide 9, we would note that professional societies and guideline writers are taking notice of our work. In addition to the IDSA Guidelines, we now have PEMGARDA in the NCCN Guidelines for B-cell lymphomas, which is a substantial U.S. population that deserves high quality protection. We routinely see from KOLs at medical conferences an awareness of non-relapsed death, for example, among patients who undergo CAR-T therapy or deep immune ablation to manage lymphomas. In infectious disease deaths, COVID-19 is again a dominating contributor to that. Moving to Slide 10. Of course, in contrast to other infectious diseases, COVID is ever-present and characterized by periodic waves. While the sales of COVID-19 treatments are highly influenced by surges in disease, and we saw that clearly among certain bigger pharmaceutical companies in their Q1 earnings calls, prevention via monoclonal antibody may be a bit more predictable and steady. COVID is always a threat for these populations. As we go into the warmer months, we tend in the U.S. to see waves of COVID-19 among the Southern states. They will be launching a targeted digital campaign regarding the likely summer surge accordingly. Finally, on Slide 11. On pricing, we took in March a modest price increase, and still, PEMGARDA remains one of the lowest priced antibodies ever launched. Obviously, the original pricing analysis contemplated larger volumes and potentially lower risk and lower acuity patients, especially considering the potential for COVID-19 treatment. With treatment off the table for the moment, we took a small price increase to better reflect the value this medicine brings to populations in need. Note, the price increase only took effect in March and will be updated by CMS beginning in July. We’re pleased that PEMGARDA continues to be available through EUA and maintain a focused commitment on serving the immunocompromised community. I’ll now turn the call over to Robbie to discuss some of our progress in research and development.

Thanks, Tim. It’s an exciting time to be in infectious disease prevention and treatment as the central authorities in the United States reconsider the state of the world for COVID-19 and beyond. I’ll begin on Slide 14 by commenting on our now multiyear work with antibodies directed against the receptor binding domain or RBD of the SARS-CoV-2 spike protein. This is obviously a validated target and has been targeted repeatedly by our colleagues and competitors and other companies who would like to produce highly effective treatments and preventatives for COVID-19. The challenge they and we faced and that we believe we are overcoming is evolutionary. Invivyd proprietary technologies are designed to yield antibody medicines that target special real estate on a biological target in motion such as SARS-CoV-2. So far, pemivibart has been a total success on that front. When we back-of-the-envelope calculate the sheer number of mammalian SARS-CoV-2 infections and consider the quantitative dynamics of infections, the fidelity of the SARS-CoV-2 polymerase, et cetera, we begin to estimate that the virus has explored quadrillions of molecular variants over the past years. And throughout the epitope that defines the pemivibart binding site has remained structurally intact. Accordingly, the product potency has assessed in best-in-class industrial systems has remained stable. Reassuringly, of course, for our pipeline molecule 2311, VYD2311, the same is true; only EC50 values are holding more stable at much more potent levels. In fact, neither the measured potency nor any change for VYD2311 would be visible if we placed our neutralization data onto the chart at the bottom of Slide 14. Why? Slide 15 shows a graphical depiction of the SARS-CoV-2 spike protein with a blue area shaded indicating the pemivibart epitope. The genetic and structural changes observed over time at each amino acid residue in the spike are represented by intensity: yellow for minor, orange for moderate, and reddish for substantial change. You will note some yellow in a few spots of our epitope, but that change was all in the Omicron transition. Ever since then, for years, which can be in some ways considered a new phase of the pandemic or a very different endemic phase, our binding site has remained quiescent. More, as vaccination rates have dropped, pressure applied to the RBD at the population level has also dropped. Even more intriguing, data out of the Bloom Lab at Fred Hutchinson demonstrates that children who have not been vaccinated but who have been primarily infected by XBB virus variants appear to generate antibody suites directed more toward the internal domain and away from RBD. While these NTD mutations are in keeping with the known immune-evasive properties of Omicron variants, there appears to be less evidence of selective pressure at those classically and historically antigenic sites on RBD near the pemivibart binding site and viruses isolated from these more recent childhood infections. In short, we feel very good about continued pemivibart activity over the long-term based on the observed stability of the pemivibart epitope. Slide 16 provides a little more color on a discovery program we are moving through now related to RSV. Respiratory syncytial virus is a major medical burden, and there is a well-developed commercial category devoted to the use of monoclonal antibodies to prevent infection in neonates and children under two years at risk from seasonal RSV. At present, Nirsevimab or Beyfortus is the class-leading antibody, although Pavilizumab is still used, and Merck’s Clesrovimab has a near-term PDUFA date. The two more contemporary antibodies have certain strengths and liabilities, and the variation of the target F protein makes the RSV landscape an excellent opportunity to see if our platform can generate an attractive medicine to compete with the class leaders. In our screening and engineering, we can establish certain parameters designed to yield best-in-class properties, and we will look forward to updating on our progress later this year. Slide 17 provides further detail on our recently announced measles discovery program. By degree, measles shares some of the same features as COVID and RSV in terms of multiple circulating variants that require an engineered, broadly neutralizing monoclonal antibody, but which also presents a highly validated antibody target considering the generally understood efficacy of, for example, both MMR vaccine and IVIG in the post-exposure prophylaxis setting. We have begun our work, and our goal would be a tool useful for the treatment of acute infection and also useful in post-exposure or even pre-exposure prophylaxis use cases. We will look forward to reporting on our progress before the end of this year. I’ll now turn the call over to Mark Wingertzahn and Marc Elia to discuss clinical and regulatory.

Thanks, Robbie. Good morning, everyone. In early February, we re-reported our initial progress with VYD2311, our next-generation antibody designed to improve upon pemivibart. As a reminder on Slide 19, all Invivyd COVID-19 antibodies share identical scaffolding, and generally, our discovery process works such that each successive monoclonal antibody is a minor but essential tweak from the last. This process results in molecules that are near identical in terms of amino acid sequence, in fact, generally change about to a similar or even lesser extent than, let’s say, mRNA COVID vaccines from one generation to the next. With VYD2311, we are not trying to solve a problem related to variation or some threat to pemivibart activity. Rather, we are trying to engineer more medically and commercially attractive features into our medicines. Slide 20 quickly outlines our first in-human dose and route of administration ranging clinical trial designed to provide maximum forward flexibility for our go-to markets and regulatory conversations. You can see the cohorts on the slide and the concepts behind assessing them initially. We will be wrapping up the study soon and will be pleased to provide an update in the next weeks on our progress. Turning to Slide 21, it reminds us very quickly of the properties of VYD2311 relative to pemivibart and what we think those properties allow for. It is our belief that 2311 can be a major step forward for people sick with COVID-19 and people highly vulnerable to COVID-19, whether immunocompromised or not. VYD2311 represents a potential step change in accessibility and scalability for protection compared to PEMGARDA and may present the opportunity to also create a highly efficient and effective treatment. With that, I would like to turn the call back to Marc Elia, who will discuss a regulatory experience with our COVID-19 treatment EUA request and some next steps.

Thank you, Mark. As previously mentioned, we have been watching evolution at HHS and FDA with great interest. One of the key messages new HHS and FDA leadership has sent has been a desire for greater transparency, especially as it relates to communication between FDA and industrial sponsors. At this time, we have not seen any convention emerge on this front among our colleagues in industry, nor do we have any guidance on this topic from the agency. However, we are aligned with the notion that transparency is a generally good thing for regulators, patients, sponsors, and citizens. With that in mind, and given the sheer volume of correspondence companies like ours have with the FDA, we are today beginning by providing direct excerpts and data from one recent correspondence back in February, specifically the declination by the legacy Biden FDA of our application for expansion of our EUA to include treatment of active mild-to-moderate COVID in immunocompromised persons with no treatment options. This action generated many questions to our company from HCPs and patients, and we hope that today’s presentation provides some answers. Importantly, we believe our presentation today reflects both the core of scientific review by the agency and the bulk of their communication to us on the topic, and would resemble in some ways the major points the agency might render to, for example, an advisory committee if that were an operative forum. We are including our rebuttals to those points, which ultimately will build to our intended next steps. Importantly, at Invivyd, we are Americans and taxpayers, and some of us are patients too, in addition to industrial sponsors, and so we view our partnership with FDA as fundamentally collaborative on behalf of patients in need. Slide 22 describes the operative background. Immunobridging of antibodies for COVID-19 has its roots in a December 2022 joint EMA-FDA webinar attended by regulators and academic and industrial experts, including Invivyd, and was devoted to accelerating COVID-19 monoclonal antibody development. In our case, our immunobridging prototype molecule, adintrevimab, went through full Phase 3 registrational RCTs for both PrEP and treatment of COVID-19, and as such, adintrevimab represents a biophysical profile well-associated with demonstrated placebo-controlled clinical efficacy. Industry, academic and regulatory confidence in sVNA titer or clinical antibody antiviral activity is sufficiently high to use that surrogate as a way to bridge from one dataset to a new molecule without the need for full preauthorization clinical studies, just as we did for our PrEP authorization. From a regulatory perspective, it was clear in 2022, and has been clear for the last three years, that EUA was the pathway FDA preferred or believed was the best fit with what was understood to be a short, useful life of all COVID-19 monoclonals. This is, of course, a contrast to vaccines, which enjoy full approval and SPLA updates on the basis of similar comparative titers. Either way, in the spring of 2024, a bridging EUA for treatment seemed to be a structure that might suit both our and FDA’s interest sets, depending on the nature of the titer bridge, just as was the case for our PrEP authorization. The clear desire from the agency throughout has been for what they would consider, quote, conservatism, unquote, or the highest possible antiviral titers, and therefore antibody dose, to satisfy some of the epistemological limitations of immunobridging. This is an understandable desire, if you remember that the first job of the agency is assurance or confidence in likely clinical benefit, rather than stewardship of a medicine’s overall profile. There are, of course, consequences to the degree of assurance required by the agency that takes some careful thought in unpacking, which is where we’ll spend some time today. It is an important exercise, in part for reasons embedded into our Citizen Petition. There is a wide gap between the assumptions and habits of CBER and CDER, respectively, as between assurances traditionally required of COVID vaccines versus assurances traditionally required for COVID monoclonal antibodies. And we believe regulatory evolution is required for the benefit of patients in need. A few more background points. First, pemivibart and adintrevimab, despite being near identical molecularly, have very different potencies and hence different routes of administration and doses, which means their PK and PD profiles cannot overlap but can be easily compared to one another visually and quantitatively. Second, the proposal for EUA expansion was for immunocompromised persons for whom alternative therapies are inaccessible or not clinically appropriate. So the choice here is between pemivibart or nothing. Third, we will not touch much on the pemivibart safety profile in this overview, both because pemivibart was and remains authorized for use by people who are well, which would seem to create a safety pathway for use by people who are sick, and because the bulk of FDA feedback relates to the science of assurance of efficacy benefit in immunobridging. Slide 23. The major FDA finding on the application for treatment presented in terms that are drawn straight from the EUA statute is that they are unable to reasonably conclude that the known and potential benefits of pemivibart in treatment outweigh the known and potential risks. They offered four specific scientific conclusions related to assurance of clinical benefit in the immunobridging exercise, which we have paraphrased here and will present in more detail on the next slide. Slide 24 depicts curves and comparison between adintrevimab and pemivibart PK and PD expressed as sVNA titer or clinical antiviral activity, the primary basis for immunobridging. On the upper left chart, you can see that adintrevimab being administered intramuscularly starts with very low circulating titers and rises slowly over five days to seven days toward its peak. By contrast, pemivibart is dosed intravenously and so begins instantly very high and then settles over time. You can read below the FDA interpretation of the comparative curves, which they describe as, quote, similar to or higher than, unquote, adintrevimab for only three days, after which it is less than. And you can see a table in the upper right expressing the ratio of those two curves over various increasingly longer time periods. The agency here is justifiably focused on whether pemivibart delivers comparative titers to adintrevimab for the longest possible time. Next Slide, 25, conveys our perspective on this primary immunobridging. In contrast to FDA description, we see pemivibart titers as much higher than or comparable to adintrevimab for four days, then modestly below for day five, after which the pemivibart titers settle below adintrevimab but are, of course, still quite high compared to nothing for many days and then weeks, given the half-life of the molecule. Why are we at Invivyd so interested in five days? Three reasons. First, over five days, adintrevimab conferred the majority of its measured virologic benefit compared to placebo, even starting at very low titers. Second, treatment alternatives, Paxlovid and Lagevrio, are five-day regimens themselves, after which, of course, they stop and confer zero antiviral activity. And third, as a general statement, treating early in the course of an infection of COVID-19 is associated with improved outcomes. So to us, that five-day duration comparison is rather interesting, and the seven-day comparison is attractive, although we agree that conferring long-term antiviral activity to help with persistent shedding or viral rebound is a wonderful potential benefit of using long-acting antibodies in treatment settings. Finally, to us, while an immunobridging analysis like this one compares a predicate antibody to a new antibody, of course, for patients in need today, the actual choice in front of the FDA is between the new antibody and nothing at all, to which we will return in a moment. Slide 26, next slide, depicts one of two conceptually and substantively similar meta-analyses presented to the agency. In this case, you can see that pemivibart is not among the most potent antibodies ever developed for COVID-19, which we understand and agree with. It is, however, well within the range of effective MAB titers and would provide antiviral activity a good bit above sotrovimab used to treat COVID-19 to great effect in the pandemic phase of COVID-19. Also on this chart, on the right side of the curve, you will see convalescent plasma titers. Convalescent plasma, interestingly enough, retains a treatment EUA, and you can see that the range of antiviral activity conferred by convalescent plasma is far below both sotrovimab and pemivibart. Nonetheless, the FDA notes here that they would wish pemivibart to be nudged more to the right to sit among other mAbs, irrespective of the fact that moving rightward appears to have a de minimis predictive effect on expected clinical outcomes. Slide 27 presents our view on this point. Moving rightward may confer some benefit to patients, and we may be able to do it with newer molecules, but alas, we are again not picking between all of these molecules as if any of the comparators currently exist. The only active molecules depicted on this chart are pemivibart and the components of convalescent plasma well to the left. Further, agency leadership was well aware and communicated to us in the past that antibodies have been consistently overdosed, which seems like a minor, maybe even academic problem until now, when a decision has to be made about an antibody like pemivibart. We look at the activity conferred by pemivibart and see it as well in an antiviral range validated by RCT as having an attractive treatment effect. Slide 28 is the FDA language describing the residual clinical uncertainty of what pemivibart dose may be optimal for those severely immunocompromised patients who are fighting an active infection without adequate immunologic response. Slide 29 notes that there is a peculiar and deeply unfortunate consequence to the FDA’s perspective for patients in such clear need. Slide 30 relates to the fact that, indeed, comparator antibodies are different and may have subtle differences in mechanism of action, and those differences may be difficult to measure but weigh on regulatory consideration. Slide 31 notes our view that, indeed, other than neutralization activity, we assessed and found effector function essentially identical between pemivibart and adintrevimab, which should not be a surprise given the identical backbones. As for antibody non-neutralization, non-effector activities that are undescribed and unmeasured by both industry and FDA, those are a little hard for us to assess and respond to. We would humbly submit that these ambiguities are ever present in medicines new and old, and, indeed, we would welcome guidance on what unknown and undescribed thing we might measure going forward. So, Slide 32, where are we? Well, we have a new leadership team at the FDA, a changing agency, and as described, changing priorities at FDA and HHS. We intend to continue engagement with FDA, both on pemivibart, which is here today, and on our new molecule, VYD2311, which we have rapidly accelerated through early clinical development. As a final point on the matter, Slide 33 depicts the result of a similar analysis for bridging to treatment for VYD2311 using arithmetic from currently circulating variants. You can see on the Y-axis that both proposed doses of VYD2311 provide sVNA titer well in excess of adintrevimab and indeed can either approach from below or well exceed the titers delivered by Regen-Cov, which sat toward the top of the old antibody leaderboard, if you’re keeping score at home. With data like these for VYD2311, we see the majority of the agency’s pemivibart concerns well addressed. We hope that this comparison and recitation of the pemivibart treatment declination logic answers outstanding questions in the field. We will be working up a manuscript to describe the situation for a scientific journal in the next week. In the biggest picture, we’re thrilled with the medical potential we see in our medicines. We appreciate the FDA’s alignment with our desire for greater public transparency and we look forward to reengaging with a new FDA to discuss pemivibart, VYD2311, and this field of medicine generally. Needless to say, it is our overarching goal as a company to bring important, high-value medicines to patients in need as rapidly as possible. I’ll now turn the call over to Bill Duke to talk about the financials before we move to Q&A.

Thank you, Marc. Turning to Slide 35, prior to today’s call, we released our Q1 2025 results, including PEMGARDA net product revenue of $11.3 million and March ending cash and cash equivalents of approximately $48 million. As previously mentioned, to drive long-term topline growth, we made a strategic decision to internalize our sales force at the beginning of 2025. Although this shift created a short-term headwind reflected in PEMGARDA net product revenue during Q1, we are now seeing positive momentum with a return to growth and early signs of acceleration in Q2. We are pleased with the continued execution of financial discipline, reporting a continued reduction of operating expenses. We recorded $27.4 million in operating expenses in Q1 2025 compared to $32.3 million in Q4 2024, a 15% reduction quarter-over-quarter. This was after a decrease from Q3 to Q4 of over 50%. We anticipate operating expenses will continue to decrease in the second quarter as we have manufactured sufficient supply of PEMGARDA and VYD2311, and do not plan for a significant further manufacturing expense in the near-term. Backed by a strong cash position and potential to access up to $30 million in non-dilutive funding through our term loan facility with SVB secured in April, we remain focused on growing PEMGARDA at topline revenue, continued financial discipline, and continue to target profitability by the end of the first half of 2025. I’ll now turn the call over to the Operator to open the call for questions.

Thank you. Our first question comes from Michael Yee of Jefferies. Please go ahead, Michael.

Good morning, everyone. I appreciate the opportunity to ask questions. This is Kyle Yang from Michael Yee. I have a couple of questions. First, could you provide your insights on your recent interactions with the new agency, especially regarding your Emergency Use Authorization for COVID prevention and future applications, including treatment and the use of surrogate endpoints like virus titers for approval? Secondly, regarding Q1 sales, could you elaborate on the challenges you faced during that quarter? I know your team touched upon it briefly. Could you provide more details on how you addressed those areas for improvement in Q2 and share your thoughts on sales expectations for Q2? What gives you confidence that the momentum will carry on into the second quarter? Thank you.

Great. Thanks so much. Let me start and then I’ll ask Tim to answer the second part. So regarding EUA, you asked a couple of different things, but with respect to maintenance of EUA, it is actually our preference to move with the FDA beyond that construct. Indeed, it’s generally understood that EUAs are designed to effectively convert at some pace and subject to some mechanism. We’ve not had that conversation with the new FDA, which, as you may or may not know, is effectively recently seated, but we’re looking forward to it very much. Critically, our current EUA for the prevention of COVID-19 in certain immunocompromised persons, yes, was generated on the basis of immunobridging, but of course carries with it the results of a randomized clinical study interrogating both safety and exploratory clinical efficacy. So in our minds, those data are unique in the field. This is the point we’ve raised in a few different domains, particularly our recent Citizen Petition. So unlike any other company we’re aware of that has an authorized preventative or approved preventative, we actually have contemporary efficacy data and so would seek to leverage that in one form or another subject to discussion with the FDA about moving toward BLA. That would be our preference and it would certainly be our preference going forward. So I don’t think any of that is either nerve wracking nor surprising. It’s in fact embedded into the very nature of a granted EUA and we’re really looking forward to talking with them about that. On a go forward basis, I think what we see is a pretty clear scientific, and I mean, sort of academic and clinical understanding that sVNA titers are a highly useful validated surrogate endpoint. And you can see that embedded into, of course, the work that we’ve done with FDA to date, and in fact, the evolution of our product fact sheet, which alludes to some of the meta-analytics describing these relationships. So we see the endemic virus situation as an opportunity to normalize all of this away from EUA into a landscape akin to an accelerated approval with a post-market conversion study, which I think not coincidentally, perhaps, appears to be the direction of travel for COVID-19 vaccines. All of that is to us highly welcome and embedded into all of our plans for both pemivibart and our molecules going forward. You have to remember that an EUA does not carry an express obligation to generate randomized clinical data on the other side of it, but of course, accelerated approvals do. So we would look forward to that paradigm and it’s going to be a major feature of what we believe will be our upcoming discussions with the agency. So I hope that’s clear. If it’s not, please, please get back into the queue. But meanwhile, I’ll ask Tim to expand on our Q1 changes and our confidence going forward.

Thank you, Marc. I briefly touched on this, but reflecting on our achievements in Q1, they were quite impressive. We separated from the contract sales organization and established our own top-notch sales team, which we trained and activated quickly with the support of our human resources team. Although this caused some disruption in field activities, we were strategic in our approach and boosted our efforts through digital marketing to help fill the gap. Currently, I am pleased to share that from January 1 to April 30, we are observing a significant increase in the number of accounts and engagement from our sales team. We have shifted our focus to what we call our core four specialists, including rheumatology, where we've had a positive response and adoption, indicating this as a strong focus area for us. Additionally, regarding PEMGARDA, when I first updated you about a year ago, we had about 120 sites available. Now, our infusion finder lists over 880 sites. We are actively expanding access to PEMGARDA through various channels and are beginning to see results. I want to reiterate that we are achieving strong numbers in Q1, and we are excited about this progress.

Thank you. Our next question comes from the line of Patrick Trucchio of H.C. Wainwright. Go ahead Patrick.

Hi, good morning. I apologize for being muted. This is Luis standing in for Patrick. Thank you for the opportunity to ask questions. We recognize that these are tough times, but we value the team's efforts and progress so far. Regarding a follow-up question to what we discussed earlier, could you provide more details about the measles program and whether you plan to transition to measles? Additionally, could you share any information on the anticipated clinical trial development path and potential market size? Also, in light of your current cash position and the non-diluted loan facility, how are you planning to prioritize your efforts? Thank you.

Yeah. Let me start. This is Marc, and I’ll see, maybe Robbie can add some color. But when we’re discussing our discovery programs, that is spending that is essentially in all of our standing budgets, and it doesn’t represent a particularly incremental draw from our forecasted cash balances. It is a matter of priority. So, yes, we’re adding a program, for example, in measles, but I want to say you might have used the word pivot, which is not something that I would agree with. We’re not pivoting any more than when we leave English class and go to math class, we’re pivoting and deciding to just focus on math. We’re adding something that we think could be potentially important and that could create a lot of value for patients in need and shareholders over time. So doing these early discovery programs provides us with a basis for considering clinical development under the right circumstances. And again, as stewards of capital, we are always going to try to be disciplined about spending shareholder money only on those projects that we see having a very, very attractive near-term return profile. Now, in the case of measles, there may well be some interest at the even national level and we will look forward to exploring that potential. But I don’t think you can consider any of it as a change or a particular draw on our capabilities or interests elsewhere. It is all about adding optionality and setting into place the ability to grow over the long-term, both in terms of the scale of our business, but more importantly, growing the scale of our anticipated medical impact. Is that clear?

Yes. That’s helpful. Thank you so much.

Thank you. I would now like to turn the conference back over to the company for any closing remarks.

Okay. Well, thank you very much all for joining us this morning and we will look forward to any further questions in follow-up later today. Thanks all. Bye-bye.

This concludes today’s conference call. Thank you for participating. You may now disconnect.
