Welcome to the Invivyd Third Quarter 2022 Update Call. I will now turn the call over to Kyra Faircloth, Vice President of Government Affairs, Advocacy and Corporate Communication.

Thank you for joining us today. Before we get started, I wanted to attend to a few housekeeping items. I invite you to review our press release and the Q3 financials included with them both of which can be found on the investor section of our website. I would like to remind you that during today's discussion, we will be making several forward-looking statements. Forward looking statements include statements concerning, among other things, the future of the COVID-19 landscape including the expectation of continued evolution and emergence of new variances of variants. Our ongoing research and clinical development plans including the timing of such plans, technology and resources to develop therapeutic or preventative options for other infectious diseases, our expected cash runway, and other statements that are not historical fact. Other factors that may cause our actual results to differ materially from those expressed or implied in the forward-looking statements are described under the heading risk factors in our filings made with the U.S. Securities and Exchange Commission, including our most recent quarterly report file today. It is now my pleasure to welcome the Invivyd management team to the call. I'm joined by David Hering, CEO of Invivyd, Laura Walker, Chief Scientific Officer, and Fred Driscoll, Interim Chief Financial Officer. With that, I'd like to turn the call over to Dave.

Good afternoon, and thanks for joining Invivyd third quarter call. It happens to be our first quarterly earnings call as a public company and my first call as Chief Executive Officer, so our agenda will be just a little different than it may be going forward. Specifically, I'd like to start by sharing my enthusiasm for Invivyd in our future. Then our CSO , Laura Walker will describe our unique capabilities, pipeline and ongoing activities. I will then come back and talk a bit about near term opportunities. Finally, our interim CFO Fred Driscoll will walk through our financial results after which we are happy to open the line for any questions. As always, we will be glad to follow up with analysts or investors one on one following this call. As you may recall, prior to joining Invivyd my role at Pfizer was the global franchise head for the mRNA portfolio. Essentially, I have the operational responsibility for the COVID vaccine in the U.S. which included worldwide production allocation and the sale of the vaccine, which is now the market leading mRNA vaccine for the prevention of COVID-19 and future mRNA products and development. Being involved in that effort was a great privilege, given the urgency of the medical situation and the ability to make an important vaccine broadly available. At the same time, it was made clear that there would always be practical limits to the benefits of SARS-COV2 vaccine to provide especially for vulnerable populations, such as the immunocompromised or other people who may not respond well to vaccination. After all, neutralizing antibody titers in response to natural SARS-COV2 two infection weighing relatively quickly, rendering all humans vulnerable to repeat infection. Over the past year, we, alongside the broader scientific community have learned that viral evolution can…

Thanks, Steve. It's an exciting time in Invivyd. Recently, we announced that we've nominated our proprietary combination, anti SARS-COV2 receptor binding domain or RBM studies for clinical development, which we are calling NVD 200. We look forward to describing the properties of these antibodies further, as we advanced towards clinical development. But of now one number of that combination is indeed a reengineered version of Adintrevimab our former lead molecule. This reengineering is an important subtlety, as our ability to evolve in Adintrevimab to rescue its activity against Omicron and its sub lineages with relatively few amino acid changes, supports our founding hypothesis, that there are indeed sites on the SARS-COV2 RBD that one can target with a monoclonal or multiple monoclonal and exert broad neutralization before through emerging variants of concern, as well as backwards to prior SARS-COV2 variants, and even more divergent for beta viruses such as SARS-COV2. As David mentioned, our plan is to utilize our integrated discovery platform against the threat of ongoing SARS-COV2 viral evolution, with ongoing novel antibody discovery and engineering, as well as to develop a best in class suite of early stage candidate antibodies that anticipate potential emerging variants. Our vision, which we look forward to engaging with global health authorities on in the coming weeks or months, is that a steady stream of viable antibody therapies for patients in the face of anticipated viral variation. To that end, we are pleased to announce today that we have multiple candidates in late stage discovery on track for plans preclinical activities in the first half of 2023. Each of the two components within our lead MBD to on this combination, as well as our other candidates represent unique molecules that have been shown in vitro to target distinct, amino recessive binding site on…

Thanks, Laura. As you all heard we are firm believers in the potential for our integrated development platform to generate high value antibody candidates that have a high probability of providing protection to populations in need. Regarding antibody protection, very recently in that archive, and currently out for review is a paper by Laura and other colleagues that describes a very tight relationship between the protection from symptomatic COVID-19 disease mediated by both varying levels of vaccine induced polyclonal antibody neutralizing titers and varying levels of monoclonal antibody neutralizing titers. This paper draws on sampling from vaccine recipients and participants in our recent evade pivotal clinical trial, has the scientifically fortuitous timing of studying of Bebtelovimab in a prep setting across 2021. The study included patients and outcomes across both pre-Omicron and post-Omicron virus which have different Bebtelovimab neutralization potency, in a controlled study with corresponding clinical outcomes. That embed study data, along with companion work on vaccine elicited titers, all performed in a consistent assay provide a unique natural experiment for assessing the relationship between protection from disease mediated by vaccination and protection from disease mediated by monoclonal antibody. Obviously, a vaccine engages the immune system broadly whereas a monoclonal antibody is highly specific and its target biology. What is unusual about the observations found within our post hoc analysis is that they underline an intuitive results. The vaccine correlation of protection neutralizing antibody titers turns out to be mechanically replicable by neutralizing monoclonal antibody titers. The analysis found within the paper also shows that the degree of protection from symptomatic disease afforded by a neutralizing monoclonal falls nicely on the curve described by the degree of protection afforded by vaccination. It is our belief that these data suggest that monoclonal antibody neutralization potency, combined with associated dosing and…

Thanks, Dave, and good afternoon, everyone. For the quarter with respect to operating expenses, RV was $34.1 million for the third quarter of 2022 compared to $49.4 million for the comparable period of 2021. The decrease is attributable to the wind down of adding [indiscernible] clinical trials and manufacturing related activities. This decrease was partially offset by increased contract manufacturing expenses related to the production of materials for use in the non-clinical studies and planned NVD 200 clinical trials. Our SG&A expenses were $13.2 million for the third quarter of 2022 compared to $11.1 million for the comparable period of 2021. This increase is attributable to higher public company costs, professional services, and personnel related expenses. The net loss for the third quarter of 2022 was $45.1 million compared to $60.4 million for the comparable period in 2021. Basic and diluted net loss per share was $0.42 for the third quarter of 2022 compared to $0.98 for the comparable period in 2021. We exited the third quarter in a strong balance sheet position with cash, cash equivalents and marketable securities of $419 million. Based on our current operating plans, we expect our cash will enable the company to fund its operating expenses into the second quarter of 2024. With that said, we are currently working on a 2023 zero based budget approach looking for cost efficiency opportunities and plan to update our cash runway guidance once we complete our budget, and close our fiscal year 2022. With that operator, please open the call for questions.

[Operator Instructions] Our first question comes from a line of Michael Yee with Jefferies. Your line is now open.

Hey, good afternoon. This is [indiscernible] for Mike. Just two quick questions. One, when kind of thinking about the clinical path moving forward for NVD 200 what kind of clinical trial design are you planning given that may be challenging to find patients with new infections COVID or they're going to be highly vaccinated. So talk a bit about that. And then my second question is how are you thinking about your guidance moving forward to 2023 in terms of clinical trial ramp up, etc. Thank you.

Yes, great, thanks for the question. As you know, it's a very dynamic space. One that didn't even exist three years ago. And what we've been doing here in Invivyd is really looking at what recent sponsors have done, how they've partnered with global regulators and seeing how they bring past programs forward, knowing that it's not a one size fits all. So is it relates to where we are, as we guided, we have NVD200, which will be entering the clinic in Q1 of next year. And what we've seen is these phase one studies can be done rapidly. And while we haven't provided guidance yet on this specific clinical designs, we do anticipate ongoing data throughout calendar year 2023. And our goal is to apply the learnings that we've had over the last few years as well as learnings we've seen from other companies in this space and to do this as quickly as possible given the urgent unmet need.

Thank you.

Our next question comes from a line of Stephen Willey with Stifel. Your line is now open.

Hi, Guys, can you hear me?

Yes.

Hi, this is [indiscernible] on for Stephen Willey at Stifel. Thank you for taking my question and congrats on the quarters. So I just have a very quick question regarding NVD200. So given that there are newly emerging variants, as we all know, so like, [indiscernible] etc, you name them. So I know that you can, you guys cannot comment with exclusive details. But can you guys just qualitatively comment on neutral neutralization activity of NVD 200 against these newly emerging variants, at least just in a qualitative manner?

Yes. Of course. And thanks for the question that. As we've seen, it's becoming an incredibly pressing need, once again, seeing the reduced activity that both of [indiscernible] antibodies that are left on the market for prevention and treatment are showing. And so, for us, it really validates our approach this focus that we have on our platform, and as you've asked specifically about NVD200 and as I mentioned in our upfront commentary, we're pleased that so far, in vitro testing, that NVD200, as well as candidates, beyond that we have in late stage discovery have all shown retained activity against these current and emerging variances as you mentioned the ones that are there. And it's a really fascinating space, because previously, what we saw was this sort of singular virus change from alpha to beta to gamma. Now, what we're seeing as it's been put in the press is this swarm of scrabble variants. And so it's really even more critical that we utilize our underlying technology focused in engineering, not just searching for new antibodies and mining for new antibodies, and that is one of the areas that we feel is critically differentiated for us, and why we're so excited for where we are today.

Okay, thank you. And my second question would be more related to the receptivity of the platform. So I know you guys have been just like, observing the current evolution of like variants and I mean, like, it's been changing. So kind of, like rapidly. So with your current capability like how can you, let's say like, next like, maybe three months, if there is like, more, like, more novice variant emerges? Like, how quickly can you guys actually come up with like new potent candidates – if you guys have any idea on like time?

Yes, I mean, listen, speed is definitely the name of the game, right. And what I would say is to-date, the company has been incredibly successful focused on that key determinant. So the company's not even two and a half years old. We already have demonstrated our ability to put forward candidates, generate clinical data with meaningful clinical results, manage the curveball of Omicron, created new candidates, and have them slated to go into the clinic again in less than a year from that change. And so the whole company is now built and focused on that instability that is been observed from the virus, right. I mean, we've seen the evolution and how fast this virus changes. And so what we're targeting is with this platform not just NVD200, but planning for the probability that it as well as other antibodies will eventually have obsolescence that the virus will move past them. And so that's where we're focused to continue to do this as rapidly as possible. And more to come, we will certainly showcase that speed as we move forward. But that is how Invivyd was set up with that in mind to make sure that we can get ahead and stay ahead of the variant.

All right, great. Thank you very much. Thank you for my question.

[Operator Instructions] Our next question comes from the line of [indiscernible] with Guggenheim. Your line is now open.

Hi, guys. Thanks for taking the question. Interesting work by Laura. Have you guys discussed the surrogate marker with FDA and other regulatory agencies? Just wondering how the conversation with the regulators has gone recently?

Yes. So we don't comment specifically on, conversations that we've had with global regulators. But what we can say is that this approach is certainly something that we're hearing and seeing in the broader scientific community. We all have noted the need for increased speed. And we are now generating this data, this paper is available on that archives. We'll be posting it as well, on our website. We're looking for it to eventually get published, but it is available in preprint. And we think it really covers a lot of these critical components that we're talking about, which is, how do we continue to have products that can meet the speed of the virus knowing that these huge populations in immunocompromised in particular etc, are being left underserved with the current situation that we have. So we are really excited about this recent scientific work that we've done with this paper, and we look forward to having conversations, both with global regulators and the weeks and months to come up, weeks and months to come as well as that the broader scientific community.

Great. And I have just one follow up. How should we be thinking about prioritization of prevention versus treatment opportunities, particularly given lack of available options for certain patients on the prevention side? Thanks.

Yes. We certainly see prevention is the most critical opportunity in particular as I mentioned, for populations like immunocompromised. This is a group that even if the vaccines were working perfectly, which they are not, they would still be left underserved, given their immune systems and their lack of being able to create really meaningful immune responses. And so for us, that is the key area. It's certainly one that we've seen with [indiscernible] and the uptake, which continued even with their Q3 numbers, this announcement today, that just continues to grow and then necessity there continues to grow. And so what we've seen over time is a shift in antibodies being utilized for treatment into prevention and we anticipate that continuing and it's certainly our highest priority.

Great, thanks, guys.

That concludes today's question and answer session. I'd like to turn the call back to David Hering for closing remarks.

Thank you so much. And thank you all for joining us for our first quarterly earnings call. It concludes our meeting for today. As always, we're happy to follow up with analysts or investors one way, one-on-one after the call tonight and tomorrow, but thank you all for joining.

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