Thanks, Tryn. The highlight this quarter is that we are advancing assets from two AbCellera-led programs into IND-enabling studies. The first asset, ABCL575, targets OX40 ligand and is being developed as a potential best-in-class therapy for the treatment of atopic dermatitis and other indications in autoimmunity and inflammation. We discovered ABCL575 during our collaboration with EQRx as part of the co-development program that was initiated in 2021. We took ownership of this program in September after EQRx was acquired by Revolution Medicines. ABCL575 has been designed with potency, PK and developability to enable less frequent dosing, which provides a potential for differentiation. At present, we believe ABCL575 has the potential to be one of the first assets to follow amlitelimab, which is being developed by Sanofi and which recently had a positive Phase II readout, providing evidence for the potential of this new class. Our second asset, ABCL635, targets an undisclosed target with an indication in metabolic and endocrine conditions. It has the potential to be a first-in-class therapy in a market segment estimated at more than $2 billion in annual sales. For strategic reasons, we will disclose more details of this program and indication only once it reaches the clinic. ABCL635 is the first AbCellera-led asset derived from our GPCR and Ion Channel platform and is aligned with our strategy of leveraging our expertise and technology advantage to create an internal pipeline of first-in-class assets. We anticipate additional development candidates in the next 12 to 18 months from this platform, and we will announce them only when we have committed to move them forward into IND-enabling studies. We would caution that studies leading to an IND carry significant risk. That said, if things progress as expected, we would anticipate IND submissions for both ABCL575 and ABCL635 in 2025. For both programs, we see the potential to get early efficacy data from clinical trials. We believe that these two assets and future programs will provide growing evidence that we can repeatedly generate potential first-in-class and best-in-class therapies. Given the breadth of our discovery activities, we anticipate generating more assets than we will have the bandwidth or capital to advance ourselves. Thus, we will be selective in the ones we bring forward into the clinic and expect partnering and out-licensing to remain an important part of our strategy. Turning to partnering. In September, we announced a new partnership with Incyte, working in the area of oncology. We also expanded our existing collaboration with Regeneron. Under the original agreement, Regeneron has exercised its rights to advance antibody candidates from two completed programs, including one against a GPCR target. Other programs are still active. In addition to the two partnerships completed in the quarter, yesterday, we also announced a collaboration with Prelude Therapeutics to co-develop novel precision antibody drug conjugates, or ADCs, in oncology. We are excited to be working with the Prelude team on the development of a new class of therapeutics, with the first program focused on antibodies armed with small-molecule protein degraders. In summary, I would like to highlight that developments over this quarter are aligned with key business objectives that we laid out last year. First, we said we would select at least one candidate from our GPCR and Ion Channel platform and at least one candidate from a co-development platform for IND-enabling studies in 2023. With the commitment to advance ABCL575 and ABCL635, we have achieved that milestone. Second, we said we would focus on high-value strategic partnerships. Our deals with groups like Regeneron, Prelude and Incyte are aligned with this strategy. We also said we would advance our T-cell engager platform and expect to enter into a significant transaction in 2023. The science and development of this platform continue to progress as expected. And tomorrow, our team will be presenting new data at SITC in San Diego. While we haven't completed a transaction yet, we have increasing conviction in our TCE platform, both in its potential to generate internal assets and as a basis for strategic partnerships. And with that, I will hand it over to Andrew to discuss our financials.

Thanks, Carl. First, let me highlight the progress made on our key business metrics during the third quarter of 2023. This quarter, we worked on four new discovery programs, taking us to a cumulative total of 110 partnered program starts. And as a reminder, the number of starts in any given quarter will be irregular. Over the trailing 12 months, we've started work on 18 partner-initiated programs. We agreed to five new programs under contract in the quarter and ended the third quarter of 2023 with 182 programs under contract with 42 unique partners. As we've stated in the past, we continue to focus on strategic partnerships rather than on deal volume. Our key business metrics do not include programs that are initiated by AbCellera internally. In Q3 of 2023, we saw NovaRock advance an additional molecule into the clinic for a cumulative total of 10 molecules in the clinic. We view our growing list of molecules in the clinic as specific examples of our near and midterm potential revenue from downstream milestone fees and royalty payments in the longer term. Turning to revenue. Revenue in the quarter was approximately $7 million, almost entirely driven by research fees related to work on partnership-initiated discovery programs. This compares to research fee revenue of approximately $8 million in Q3 of 2022. This reduction of research fee revenue is consistent with our increasing focus on more strategic partnerships, where AbCellera has a larger participation in the long-term value of the program. This quarter's revenue also includes some small amounts related to licensing fees. Unlike a year ago, there were no royalties and no milestone payments earned in the quarter. Turning to operating expenses. Our research and development expenses for the third quarter were approximately $38 million, representing a roughly $11 million increase over the same period of the previous year. This increase reflects the growth of program execution, continuing platform development and our investment in internal programs. In sales and marketing, expenses for the quarter were $3.5 million compared to just over $3 million in Q3 of 2022. In general and administration, expenses were just over $14 million compared to just under $14 million in Q3 of the previous year, reflecting good operating leverage. Looking at earnings, we're reporting a net loss of roughly $29 million. This compares to earnings of approximately $27 million in Q3 of 2022, the loss reflects our continued investments in the business and the absence of the royalty revenues that were present in Q3 of the previous year. In terms of earnings per share, this quarter's results work out to a loss of $0.10 per share on a basic and diluted basis. Looking at cash flows, operating activities for the first nine months of 2023 used roughly $24 million. In the absence of regular royalty revenues, we would expect our quarterly operating cash flow to be irregular and often negative as we continue to invest in the growth and capabilities of the company. Of note, from operations and investment activities in the third quarter, we used approximately $10 million of cash. As part of our treasury strategy, we have over $600 million invested in short-term marketable securities. Our investment activities for the first nine months of the year include approximately $113 million net increase in these holdings. All other investment activities amounted to approximately $95 million, including approximately $62 million invested in property, plant and equipment and approximately $37 million in other long-term investments. Investments in property, plant and equipment are, of course, driven in large part by our ongoing work to establish CMC and GMP manufacturing capabilities. Altogether, we finished the quarter with over $813 million of total cash, cash equivalents and marketable securities. We have historically been successful at raising nondilutive sources of capital. As a reminder, our continuing GMP facility build-out is separately co-funded by the Government of Canada's Strategic Innovation Fund. This available capital does not show up on our balance sheet. With over $800 million on the balance sheet and the unused portion of our previously secured government funding, we continue to have over $1 billion in total available liquidity. This is more than our liquidity position from one year ago when we reported our Q3 of 2022 financials. With respect to our operating expenditures, our capital need programs towards and into the clinic with excellent visibility and runway. We continue to believe that we have sufficient liquidity to fund well beyond the next three years of platform and pipeline investments and overall growth. And with that, we'll be happy to take your questions.

The first question will be from Allison Bratzel with Piper Sandler.

Thanks for the update. I guess could you maybe just speak more on what we can expect to see for the T-cell engager platform tomorrow in the posters at SITC? And really just help frame what's the bar you think potential partners are really looking for in order to have confidence that your TCE platform really is best-in-class and pull the trigger on a partnership. Your latest thoughts on the setup there would be really helpful.

Sure. Thanks, Allison, Carl here. Happy to take that. So we have continued to make great progress here. The SITC presentations really focus on two developments on the R&D platform. One of them is the advancement of the platform towards being able to generate antibodies against MHC peptide targets. We see that as highly differentiated and a capability that opens up a broad array of targets that are expressed inside the cell, but that get presented to the surface of the cell and are highly specific to tumors. So being able to do that solves one of the key problems in TCEs, which is being able to find targets that are specific and reduce the on-target off-tumor toxicity. The other big highlight is evidence that shows that combining a broad diversity of CD3 binders with the OrthoMab platform and being able to change both the affinity of binders and the epitope importantly, allows you to obtain profiles in the mixture of cytokine release and killing that cannot be obtained using just affinity alone or many of the existing antibodies. That was the original thesis, and we have continued to push that forward and see it as very compelling in cases in particular where dose-limited toxicity has been a problem. What's not being shown at SITC, but something we're also excited about is more recent data that very clearly shows that you can decouple cell killing from cytokine release. That's something that has been pursued for some time. In our hands, we think we have by far the clearest demonstration of that compared to benchmarks that we've tested our antibodies against. So all of that is going very well. The timing of a transaction, I think, is always difficult to predict. But we are engaged with the top groups and have built relationships over the last year. On all fronts, I think it's going in the right direction.

The next question will be from the line of Robyn Karnauskas with Truist.

I have a question that might be challenging to answer directly, but perhaps you can provide a broader perspective on your capabilities. This morning, Regeneron stated that their OX40 may not be optimal, suggesting that the target might not be safe compared to Dupixent. How can you approach the design of this molecule differently to enhance its specificity or achieve a safer therapeutic index? If you're unable to discuss that particular molecule for competitive reasons, could you speak more generally about your capabilities? Many companies are encountering similar issues with suboptimal drugs that could be improved. How are you tackling these challenges?

Sure, Robyn. I'm happy to take that. So I think your question was related to ABCL575, which is our antibody that we're bringing forward against OX40 ligand. Maybe a few things to say about that. We're excited about that one for a few reasons. One is, we see this as a very compelling class, not just for atopic dermatitis, but for a wide array of different conditions and inflammation. It is a pathway for which there is a robust scientific literature that suggests that it is able to affect multiple pathways in the inflammation cascade and that it can do it in a way that not only suppresses the activation and proliferation of T-effector cells and T memory cells that are associated with disease, but also that can interact with T regulatory cells to help to reset homeostasis in the immune system. That body of evidence makes it a compelling pathway. The recent readout from Sanofi that we mentioned looks completely in line with that. So it looks to be safe. It looks to be effective. What was interesting in that study is that the effects seem to get better over time, which is what you'd expect if you were able to reset the immune system. So for all those reasons, we think the pathway is very exciting and has broad potential in a growing space in atopic dermatitis and also in other conditions. ABCL575, as I said, we believe, is one of the first behind it. Now you don't know what people have inside their pipeline that they haven't disclosed. But based on disclosures, we think this one has the potential to be one of the first to come behind it. We have engineered it in a way that we think provides the combination of potency and developability and formulation and half-life that would give an advantage in dosing. So that's why we're excited about that particular one. As it compares, I think you mentioned Regeneron and Dupixent. Dupixent is obviously an amazing drug. Our view is that in inflammation, not every patient responds to the therapies that are available, and there is a lot of interest in finding alternatives and perhaps even combining therapies in the future. So we don't see that as a negative at all, but rather as an example of the huge opportunity that exists in this space.

As a follow-up, do you believe there is room for improvement? Their perspective seems to be that the existing options on the market are not effective enough, or maybe they're too general. What aspects of AbCellera's technology could you leverage to develop a better OX40, especially since it's a very promising target right now? Perhaps you could also highlight the technology, and then I'll return to the queue.

So to be clear, we have an antibody that is going to get OX40 ligand, not OX40. There is, of course, an OX40 antibody that is being developed by Amgen. That antibody is a depleting antibody. It binds to OX40, which is presented on T cells and causes the ablation of those T cells. There's some evidence that that may cause problems. I mean, I don't want to speculate too much. The antibody that we have engaged in OX40 ligand, which is not presented on T cells, but rather on antigen-presenting cells. Our antibody has been engineered to be non-ablating. It has Fc Function that does not result in the killing of the antigen-presenting cells, very similar to amlitelimab, which I mentioned, which is being developed by Sanofi. We don't see a problem with it being dirty. We don't see a big problem with toxicity. Of course, we're getting that information from the disclosure that Sanofi has made, and they've got the most advanced molecules. To our knowledge, this looks like a quite clean profile, and one that's effective with significant potential in inflammation and other conditions.

The next question will be from the line of Andrea Tan with Goldman Sachs.

Carl, maybe one more question for you on 575 here. Strategically, can you speak to the decision to pursue atopic derm as the initial indication? Just curious given how crowded that landscape is. If there are other indications where mechanistically, it might make sense to also bring this asset forward but one where you could have an advantage of being first-in-class.

That's a great question. I mean atopic dermatitis is the most obvious place because there is data out already showing efficacy. It's also in derm one of the easier places to get early clinical data that shows efficacy, let's say, in a Phase I or IIa trial. So that's probably the main reason. We feel based on the pathway and what we've seen in the clinic from other molecules that this has a very high likelihood of working, not just in atopic dermatitis, but in other conditions. That's our sense right now. But this is a competitive space, as you mentioned. So right now, what's most important is that we not delay in getting this molecule through to the start of clinical development and through the early trials. There's going to be a lot of consideration and thinking between here and there. So we may change that, but it's also perhaps worth saying that at some point, I think it would be advantageous to find a large and highly enabled partner to accelerate clinical development because this is a molecule that would have potential in a variety of different classes and something that probably is done best by a big company. So that would be our current feeling right now in terms of subsequent steps. But as I said, the priority right now is to get this through to clinical development and get that early proof of concept. Sure, I'm happy to address that. This is a question that I often receive, usually framed as what our strategy is for internal programs. My typical response is that it's incorrect to think of a single strategy for internal programs. Each program must be evaluated on its own merits, as they will each have distinct timelines, costs, operational challenges, and clinical development paths. As we move forward, there will also be shifting priorities within the company, capital allocation changes, and various strategic opportunities. Currently, we are committed to advancing ABCL635 and ABCL575 through the end of Phase I. It is possible that these could be affected by the right business opportunity, but we are fully focused on achieving that milestone. After reaching that point, we will assess the risk and reward to determine what is best for the business and where we believe we can achieve the best return on investment. Advancing one of these into further trials is still a possibility if we feel that is the best direction.

And just, Andrea, if I can add there as well, this is Andrew speaking, the announcement we had earlier in the year about receiving some government funding allowed us to move molecules. That included funding molecules that we would advance into Phase I and received some significant amount of government funding that make it quite capital efficient for us to do that. So this is completely consistent with that announcement and that strategy.

The next question will be from the line of Stephen Willey with Stifel.

And congrats on procuring the OX40 ligand antibody. I think it’s interesting that you said both have been birthed by antibody platform discovery companies. I guess with respect to the Prelude deal, can you just talk a little bit about what you think makes a good antibody for the purposes of delivering a degrader? I guess do you want to have the same level of high internalization that you sometimes see on some more kind of chemo-conventional ADCs? Or is there a different kind of chemical angle that you want to take here? And just given that I think the degrader that they’re hoping to administer here this market to, which is, I think, relevant in SMARCA4 efficient tumors is probably relevant across a variety of different tumor types requiring a variety of different target antigens. Does this collaboration contemplate the notion that you could develop multiple antibody scaffolds that are targeted towards a specific tumor type, and then they can just kind of cut and paste their version of a SMARCA2 degrader on top of that?

Great questions. Let me start by saying that we’re excited about the collaboration. We have emphasized our focus on strategic partnerships. This one is certainly a 5-star strategic partnership in that we have two teams that are very experienced and have deep expertise on both sides of the molecule that you need, the small molecule development and the antibody development coming together to enable what we think will be an exciting new class of antibody conjugates. The first program, as you rightly pointed out, is an antibody conjugate for a degrader. It will be related to SMARCA. I think that may have even been mentioned in the press release. The question about what exactly do you want an antibody to do to be effective is the thing that we’re going to be working together to figure out. We’ve got some hypotheses about what might be needed. But the proof is ultimately in the assays that you do preclinically to show that you can get a good therapeutic index and deliver enough degrader at the effect that you want in the tumors. So this is the first of the programs. There certainly is the potential for that particular small molecule degrader to go into different cancers, and that would require a different antibody. So that’s on the table. The collaboration has the potential also to go into other antibody drug conjugates where the concept is to use small molecules, not just as sort of a blend instrument poison, like many cytotoxics, but to be much more targeted at precision pathways. And that could be degraders that could also be other molecular entities that the team at Prelude is able to bring forward. So we’re at the very beginning of this, and one of the big values for both teams is we get into a new space, and we’ll be learning and working together. We’re excited about the chance to do something that makes a difference for patients. Hopefully, and I’ve got confidence this will be a successful one, and we’ll be able to update you as it progresses.

The next question will be from the line of Puneet Souda with Leerink Partners.

A couple of questions here. Just maybe first a simple one for 575 and 635. When do we see the early data here for both of them? Maybe just let's start there.

Yes. For 575, I expect that we will provide some preclinical data ahead of the IND filing. I am not sure about the exact timeline right now, but we will update you as we have more information. Regarding 635, for strategic reasons, we believe it is not wise to disclose the target or the indication at this time. We will keep that information confidential until it reaches the IND stage.

And Puneet, Carl mentioned in his prepared remarks that the INDs would be in 2025.

Yes, yes. So that's related to my second question is, Andrew, can you just remind us what the level of investment or CapEx that you have towards the GMP facility, sort of the outlay that you have for 2024 here before the opening of that facility? And obviously, if you have a drug that's going to be filed into IND, there's a lot of early stage work that needs to be done. So can you maybe talk about sort of how you are going to set the priority for or who's going to set the priority for what is going to be manufactured in that GMP facility? And then maybe just if you look at the overall capacity in the CDMO landscape today, there's a bit of an overcapacity situation. Does that impact you at all as you think about how to fill that facility in '25?

Carl, here. Maybe I'll start, and Andrew can fill in if I miss something. First of all, for the first two programs, ABCL575 and ABCL635, we will be having these manufactured by a third-party since our manufacturing facility is not up and running. For both programs, we believe it's imperative these move forward as quickly as possible. The manufacturing capability should come online in 2025. That's the same year that the INDs we expect to be filed for 635 and 575. The first program through the GMP facility are very likely to be AbCellera internal programs. We also expect that we'll be doing programs that come from strategic partnerships, obviously with firms that do not have large manufacturing capabilities internally. The last part of your question was, does it affect you that there's a slowdown, let's say, in a lot of the CDMO market that I think is broadly tracking the macro environment today. Perhaps there is some effect of that, but we are expecting to use our facility not as a CDMO. We're not going to be taking inbound on molecules that we have not developed ourselves. So the pipeline that we expect to put into the manufacturing facility is molecules that have been done either internally or at AbCellera or that have been done at AbCellera in collaboration with partners. Based on that, I think we've got a good line of sight as to what will be used in the facility.

Got it. And then maybe this is a sort of a tangential question. The Beacon platform for antibody discovery changed hands and now acquired by Bruker. Could you maybe update us on if that changes your thinking a bit on the competitive landscape there? And I just wanted to make sure what's left on the litigation front there? If you could just clarify.

Yes, Puneet, I'll address that. The litigation with Berkeley Lights, now involving Bruker, started a couple of years ago. The initial response aimed to invalidate our patents, but the proceedings determined that our patents are valid and fully enforced. The litigation was paused during this process and is now active again. We plan to continue pursuing this matter in court with Bruker, and we will monitor the outcome of these proceedings, which we anticipate will progress throughout 2024 and possibly into 2025.

The next question will be from the line of Steven Mah with Cowen.

Great. On the new partner adds, can you give us some color on what you're seeing given the macro environment? Maybe give us some color on the level of your inbound and discussions with potential partners. And if these inbounds and discussions are weighted more to one type of player, larger or smaller. And I ask that given that the Prelude was a little bit on the smaller side.

Yes. So Carl, here, happy to take that. First, on the macro, I think you don't have to be a biotech analyst to see that this is a bear market for biotech and has been for some time. So what that means is that there is absolutely a slowdown in the formation of new companies and financing new companies. The companies that are out are preserving capital. They are prioritizing programs. All of that results in a smaller ocean of opportunities for partnering. So that said, we have for the last two years been consistently communicating that our focus is not on deal volume. Our focus is on finding strategic partnerships where strategic means one of two things. It either means that we found a company that is bringing a unique technology such as Prelude or a company that is bringing unique target insight and biology. Together with them, we have a great opportunity to make a therapeutic that we have conviction in and that we're able to get a significant stake in that therapeutic. So that's the first category of strategic. The second category is relationship building and setting up deeper engagements with some of the very large and well-enabled companies, companies like Regeneron and Incyte. Examples from this quarter that line up with that mean we are looking at lower volume. It also means that we're primarily looking at the bigger firms. The bigger firms are quite robust in this market. They're continuing to invest in R&D. I don't think that we're going to see a lot of impact on that, and we're just going to continue with our strategy.

Okay, great. And if I could just ask one more question. Have there been any changes to the timing of the GMP biologics manufacturing facility? Additionally, as you begin to develop that downstream capability, is it affecting your partnership discussions? I’m curious to know if perhaps the Prelude collaboration has benefited from the GMP biologics manufacturing capabilities you are developing.

Yes, I’ll address the first part of that question. We are continuing to invest in both CMC and GMP manufacturing. Our plan is to produce the initial pilot and engineering batches for CMC development in 2024. The qualification batches from the production facility are scheduled for 2025, which is also when the first batches supporting Phase I will be produced. This means that the discoveries from the programs we are starting today could progress through our CMC cell line development and GMP manufacturing capabilities. I believe this is of interest to potential partners, and I’ll let Carl provide further insights on that.

Yes. Not too much to add except that we have a variety of discussions, particularly in the space of new venture creation or early companies, obviously that are not equipped with manufacturing capabilities internally, where the integration of the front-end discovery, lead optimization, translational science, CMC, GMP altogether is a very attractive part of working with AbCellera. It provides a way to substantially shrink the time in going from an idea through to the start of clinical development and frankly, reduce a huge amount of hassle that exists, particularly for smaller firms when they're having to set up CDMO networks and relationships and manage that and jockey with the bigger firms to make sure that their programs are coming in, in the right slots and with some flexibility. We see it as a very important strategic advantage, that's why we're investing in it. It's a heavy lift to put it together, but we're crossing that right now and are confident that we'll have that in place in 2025, as Andrew said.

The next question will be from the line of Malcolm Hoffman with BML.

Malcolm on for Evan. I wanted to first ask about ABCL575. It's noted that the molecule has been designed with greater potency and PK to enable less frequent dosing than benchmark molecules. Are you able to provide more color on what those benchmark molecules are? Are they the approved assets or other in-development molecules from AbCellera?

Sure. To be clear, what I said is that it's been engineered and selected to have a combination of potency, PK, and developability, particularly meaning high-concentration formulations that we believe would allow it to be dosed less frequently than existing benchmark molecules. We are, of course, testing the ones that are disclosed out there, amongst them are the clinical assets, including the one I mentioned earlier.

Thank you. At this time, there are no additional questions registered in the queue, so I will turn the call back over to Carl for final remarks.

Thank you, everyone, for joining the call today. This remains an exciting time for AbCellera with two big milestones in advancing our development candidates forward. We look forward to keeping you updated on future calls and wish you well.

That concludes today's conference call. Thank you all for your participation, and you may now disconnect your lines.
