Matthew Foehr

Thanks, Kurt. Good afternoon, everyone, and thanks for joining our second quarter conference call. I'll start today with an overview of our business here on Slide number 4 of the deck. At the core of OmniAb's business model is our proprietary discovery technology platform that's designed to help partners discover innovative therapeutics quickly and efficiently. In a simple sense, it's a model based on licensing innovative technologies to partners. OmniAb is differentiated in the marketplace by having the most diverse host systems for fully human bispecific -- fully human and bispecific antibody discovery with the industry's only 4-species platform. That includes transgenic mice, rats, chickens and cow-based technologies.

Our partners have an increasing number of antibodies in clinical trials that are from our technology and the versatility of our platform continues to be demonstrated in the number of modalities and formats being employed by our partners, both preclinically and clinically. We offer flexibility to meet our partners' evolving scientific needs as we believe generating large and diverse repertoires of high-quality antibodies increases the likelihood of success in optimizing desired therapeutic characteristics. Our technology and our core capabilities are driven by, what we call, the biological intelligence of our transgenic animals and are further strengthened by our innovative, high throughput screening and other technologies.

There are 74 partners with access to our technology or to OmniAb antibodies with over 300 programs in various stages of research and development. The antibody space is one of the fastest-growing parts of the drug industry with a market size expected to be larger than $250 billion within a couple of years. We believe we're in a great position to capitalize on this opportunity with our unique and expanding technology offerings.

We're constantly innovating our technology stack, and this past May, we introduced our newly branded OmniDeep offering, which is a suite of in silico capabilities, including structural modeling, large, multi-species antibody databases, molecular dynamic simulations, artificial intelligence and machine and deep learning sequence models that are applicable across our technology platforms to further enhance our partners' discovery process. In addition, we plan to introduce our novel heavy-chain-only OmniChicken that we will be branding as OmnidAb in the fourth quarter of this year. And I'll say more detailed [Audio Gap] and our excitement around that technology until later this year when we launch it.

On this next slide, I just want to reiterate that as a company and as a team, we're mission-driven to enable the rapid discovery of innovative pharmaceutical products by pushing the frontiers of drug discovery technologies. We're poised for continued growth, as shown here on Slide number 6 by the new license agreements we signed during the second quarter. In Q2, our team closed 4 new platform license agreements, one with Merck, Inc. and one with Neurocrine Biosciences as well as platform deals with Stanford University and Seattle Children's Hospital. Regarding Merck, this is a new agreement and is with the U.S. Merck & Co., not to be confused with the German Merck KGaA with whom we also have an agreement. We reached a total of 74 active partners at quarter end, up from a partner count of just slightly more than 60 as of a year ago.

Our discovery platform continues to garner interest in the industry among a diversified group of leading global pharmaceutical companies, allowing us to leverage our highly scalable business model. Adding partners like Merck Inc., who are global leaders in the industry and who are committed to using the power of leading-edge science to improve lives, bolsters our growing list of partners. We believe this is a testament to our effective and efficient discovery technologies to our in-house expertise for scientific collaboration services, our mindset for developing a deep understanding and also prioritizing the current and the future needs of our partners as well as our commitment to continued innovation.

Here on Slide number 8, our portfolio of active programs increased to 305 with 29 programs in the clinic under regulatory review or approved for commercialization at the end of Q2. During the second quarter, we added a net total of 4 new programs to our portfolio. Importantly, I want to note that when we report program count, we do so net of attrition, as attrition is expected in the pharmaceutical industry. In this quarter, attrition was seen only in the discovery stage of our partner pipeline.

The pie chart on the right-hand side of the slide breaks down our 305 programs by stage of development. The discovery phase consists of 261 programs in addition to 15 programs now in the preclinical stage. In the clinic, at the end of June, our partners had 22 programs in Phase I, 2 programs in Phase II, 1 in Phase III as well as 1 program currently under regulatory review. There are 3 approved drugs utilizing OmniAb-derived antibodies, and we're recognizing royalty revenue from commercial sales of zimberelimab and sugemalimab in China, both of which are also being pursued in other geographies.

We saw some nice progression of programs in the quarter as well, with 3 programs transitioning from the discovery stage to the preclinical stage with 2 programs moving from the preclinical stage into their first human clinical trials and with 1 Phase III program moving to a regional filing for approval, shown here on this Slide number 8 pie chart on the right as BLA stage. Our large and growing portfolio features a diversified set of partners utilizing a variety of formats and modalities, as I mentioned earlier. I'd also like to note here that the count of active programs has increased from 270 in the year-ago period, up to 305 programs at the close of the second quarter, noting again that this is net of program attrition.

Despite some of the industry's challenges, including evolving financing environment and funding constraints, especially for some of the smaller players in our industry, our portfolio continues to expand from a combination of new and existing partners. We don't feel that it's entirely unexpected that macro factors can influence the velocity of growth of some of our business metrics. And although we see a slightly lower number of net new program additions compared to last year, OmniAb is in a very solid position for continued growth with an increasing number of both active programs and active partners.

Moving now on to Slide number 9. As I mentioned, in the second quarter, 2 new programs entered the clinic with Immunovant who initiated a Phase I clinical trial of IMVT-1402, which is a subcu FcRn inhibitor. Also, Gloria Pharmaceuticals initiated a Phase I/II study to investigate the safety, tolerability and preliminary efficacy of GLS-012 as a monotherapy in combination with GLS-010 in subjects with advanced solid tumors that have progressed following standard treatment. We've now had 3 new programs entered the clinic in the first half of this year, and we expect a potential 1 to 2 more to enter the clinic before year-end. I want to note that when 2023 began, we indicated that we expected 3 to 5 new programs to enter the clinic this year. By the end of June, we'd already reached 3, and we're now focused on an upward range of 4 to 5 new clinical programs for the year.

Our partners made numerous public announcements about their clinical and commercial progress during the second quarter and in recent weeks. And I'll highlight a few of them on this slide, Slide number 10, starting with batoclimab. During the second quarter, we earned milestone revenue related to advancement of batoclimab into pivotal studies in 2 additional indications of CIDP and TED. These are additional indications from the Phase III work that was started in generalized myasthenia gravis earlier in the year.

In addition, Harbour BioMed announced that China's NMPA accepted its biologics license application for the treatment of generalized myasthenia gravis. And for the same indication, HanAll announced that they're progressing towards initiation of a Phase III trial in Japan later this year. As for the next-generation anti-FcRn IMVT-1402, I mentioned that Immunovant initiated a Phase I trial to evaluate safety, tolerability and pharmacodynamics and they've communicated that initial data are expected in the second half of this year.

One of our newer partners, Cessation Therapeutics announced that they've received authorization to initiate a Phase I clinical trial. CSX-1004 was first discovered via collaboration with Scripps Research Institute and subsequently licensed to Cessation for development. Cessation is developing this compound for the prevention of fentanyl overdose, which is an indication that obviously it has an important and urgent unmet medical need.

Aptevo Therapeutics announced data for its bispecific AML drug candidate, APVO436, and that it plans to initiate 2 Phase II clinical trials in AML populations. And lastly, we achieved a research progression milestone for small molecule inhibitors of a genetically validated target relevant to neurological diseases in one of our ion channel collaborations with GSK. This triggered a $2 million progression payment for OmniAb and Kurt will discuss the accounting for this.

We're particularly excited about this program with GSK as it demonstrates the capabilities of our highly differentiated ion channel and transporters technology platform. Ion channels are key components in a variety of biological processes that involve rapid changes in cells, and they hold therapeutic potential in a broad range of indications, including neurological and metabolic diseases, pain, cancers, infectious diseases and many others. As a result, ion channel drug discovery provides a compelling opportunity, although it's been a challenging area for the industry to identify drugs to these high-value targets.

Our ion channel platform an OmniAb leverages our proprietary expertise in a combination of biological assays, medicinal chemistry and in silico and computational chemistry applications to enable the discovery of ion channels targeting therapeutics in a variety of formats and modalities. We believe our differentiated core capabilities can assist partners in their advancement of drug discovery against this target class. We're continuously expanding our capabilities in this area, and we believe we have one of the most experienced teams of ion channel experts anywhere.

We have an extensive bank of custom cell lines, reagents and assays that are designed to accelerate ion channel drug discovery and development, and that's what attracts partners to this element of our technology and capabilities. As these are higher value and more difficult targets to identify, we structure our collaboration agreements accordingly. These deals provide for exclusivity on various targets, and as a result, have higher milestone payments and higher royalty percentages than we typically get for standard platform access agreements. We have agreements with GSK for 2 neurology targets that are in discovery phase and another partner is Roche for 3 undisclosed targets that are also in the discovery phase. In total, we're eligible to receive $1 billion in milestones on these 5 programs alone, along with royalties should program be commercialized.

And this last slide for me, which is Slide number 13 in our deck, highlights our key areas of focus going forward. And it describes why we believe we're well positioned for future growth and can make an enduring impact on our industry and ultimately on global human health. Our business is highly scalable, and we're focused on increasing partners and expanding programs by continuing to invest in technologies and innovations to power the discovery and development of effective therapeutic candidates. A focus on stakeholders and building value for stakeholders is at the foundation of what we do. And that focus is guided in collaboration with our Board of Directors and it's present in every employee here as well.

While I mentioned our Board of Directors, I do also want to acknowledge on today's call that, earlier this week, with heavy hearts, we announced the passing of a beloved Board member here at OmniAb, Sunil Patel. Sunil was an accomplished biotech executive who was a longtime colleague and a co-architect of what we're building here at OmniAb. And I'll add that the team here is honoring Sunil's contribution and legacy as we continue to do our important work, expand our technology and grow our business.

And now before I hand the call back over to Kurt, I'll finish by saying that we look forward to keeping the investment community updated as we execute on our strategy. And with that, I'll pass it back over to Kurt now for a discussion of our second quarter financial results. Kurt?

Kurt Gustafson

Thank you, Matt. As a reminder, the financial results reported for the prior year periods are prepared on a carve-out basis, which were derived from Ligand's historical accounting records as if OmniAb were an independent company. As a result, certain comparisons to prior periods aren't reflective of true underlying business changes. This is primarily true for operating expenses, given the differences in corporate structure and the methodologies for reporting. You'll recall that OmniAb derives revenue from several sources, including upfront payments for partners to access our technology stack, payments related to service contracts when we do discovery work for our partners, milestone payments typically related to progress in the clinic and royalties on net sales of our partners' programs.

So moving specifically to our second quarter results. Total revenue for the second quarter of 2023 was $6.9 million compared to $7.2 million in the prior year quarter. We saw an increase in license and milestone revenue based on milestones that were hit this quarter, mostly related to progress with batoclimab, specifically the start of additional pivotal studies for 2 new indications. The increase in milestone revenue was offset by a decrease in service revenue, and this decrease is related to a few different things.

First, we've completed our portion of the work on certain programs, and these programs have been handed off to the R&D teams at our partners. As a result, we are no longer earning service revenue for these programs, but would still have the opportunity to earn milestones and royalties should these programs advance.

Second, the research period for one of our GSK ion channel programs was extended by approximately 1.5 years. The accounting impact of this extension is that the initial $7 million upfront payment that was being amortized over the initial research period had its amortization schedule adjusted to reflect the new length of the research period. This resulted in a onetime negative adjustment of $1.7 million this quarter. The full $7 million will all eventually be recognized. It's just that the recognition of the revenue will be spread over the new longer research period.

And third, as it relates to the GSK program that achieved the $2 million research progression milestone, this milestone is recognized as service revenue and will be amortized over the research period of this program. As this program is a bit more than halfway through its research period, we recognized a bit more than half of this milestone in the current quarter and the rest will be amortized over the remaining research period. The net result of the change in the amortization period and the new milestone recognition created a negative impact of about $500,000 in the quarter relative to what the trend would have been.

Turning to operating expense. Our R&D expense for the second quarter was $14.1 million compared to $11.5 million in the prior year quarter. Similar to Q1, the increase was primarily due to higher personnel costs and higher costs associated with our new facilities. G&A expense was $8.7 million compared to $5 million in the prior year quarter, with the increase related to increased headcount and other costs associated with being a newly established public company. The net loss for the second quarter was $14.7 million or $0.15 per share versus a net loss of $10.3 million or $0.12 per share in the prior year period.

Turning to the balance sheet. We ended the second quarter with a total of $103.1 million in cash, cash equivalents and short-term investments. Our business model is not capital intensive and it's highly scalable. And while we are committed to growing the business and keeping our technology cutting edge, we're also committed to deploying our capital efficiently. We continue to expect that our cash balance at the end of 2023 will be slightly higher than the balance at the end of 2022 and that this cash balance provides sufficient runway to fund our operations for the foreseeable future.

Turning to our quarterly results, I'd like to make a few comments on some of the underlying trends that we see. Excluding the milestone revenue recognized specifically for teclistamab, we generally expect total revenue to grow. However, the majority of our revenue in the near- to medium-term will come from milestone payments and the exact timing of these milestones can be difficult to predict. As a result, our revenue growth will likely be a bit lumpy on a quarterly basis.

As we think about our operating expense going forward, I had indicated last quarter that our Q1 2023 actual results would be a good baseline from which we would grow. The second quarter results were consistent with that expectation, and we anticipate this trend will continue going forward as our operating expenses are now more predictable. We're forecasting that both R&D and G&A will grow slightly in subsequent quarters with the pace of G&A spend being more moderate than that of our R&D spend.

And with that, I'd like to open up the call for questions. Operator?

Question-and-Answer Session

Operator

[Operator Instructions] Your first question comes from Puneet Souda from Leerink Partners.

Puneet Souda

So Matt, maybe first one. Obviously, you talked about some of the headwinds in the market. And as you pointed out, you have -- there's a potential that you could see that. But maybe talk to us a little bit about the flip side of what's happening at the partners and what they are telling you in terms of the projects that they can potentially bring to you because you're providing them value and cost reduction. Maybe talk to us about what -- how do they think about that as they think about discovery stages and getting into Phase I.

Matthew Foehr

Yes. Puneet, thanks. This is Matt. I appreciate the question. Yes, as we -- I mean, one of the things I'll highlight that, obviously, this quarter, we entered into 4 new platform license agreements with new partners, right? Merck and Neurocrine. Merck, obviously, is a well-known player, global force in the industry that is really committed to leading-edge science and leveraging cutting-edge technologies to develop new medicines. Neurocrine, of course, is a 30-year-plus history in innovations and success of pursuing really what have become life-changing medicines in the neurology and neurological disease space. But also new partnerships with Stanford and Seattle Children's, both of which are leading academic centers, both of which are focused on translating their novel biology into new medicines. So sometimes it's not only the existing partners that tell us a lot about how we're bringing value to them, but it's the new partners as well, right?

So to your question of how we do that, we obviously get into a lot of deep discussions with our partners of areas they're interested in and why they see our technologies unlocking opportunities for them. That obviously translates into potential for increased success rates and faster pace in terms of finding quality antibodies to then take into the clinic. And that's why they're attracted to do licensing deals with us. I think there's also a recognition now -- a more broad recognition of our continued commitment to innovation, and that is also, I think, an important part as well. And obviously, our innovation is informed by our deep relationships with partners. So there's -- like what we like to call an intelligent feedback loop, where you get a sense of where the industry is headed, and that informs the sorts of innovations and investments we want to make in our technology. So it's really, at the end of the day, about speed and opportunity and efficiency and quality of the product, in this case, the antibodies that are coming out of our platform.

Puneet Souda

Got it. And then with that question, I was wondering -- what I was trying to get to is that if the biotech funding situations were to get worse, is there an opportunity for you to sort of gain more share in the marketplace? And then let me just follow up with a question on China. I mentioned -- I know you mentioned Gloria anti-LAG-3 in the Phase I trial now. Wondering if you could update us on what you're seeing in China. We are all seeing weakness in the discovery stages in China that's well known at this point. So wondering what you're seeing there. Any color you can provide geographically.

Matthew Foehr

Yes. Yes, I'll take that, Puneet. I'll take the China part first, and then Kurt maybe can add some color as well. Obviously, we announced this quarter that Gloria entered the clinic in China. So it was nice to see -- it's always nice to see clinical progression out of our pipeline. And we obviously have a couple of drugs that are approved in China that Kurt can probably comment on as well. A lot of that, in terms of the later-stage visible programs out of China, really come out of some very early partnerships with OmniRat that were struck years ago, and those programs progress quickly through the clinic and then -- or approaching the clinic, which is really a representation of what you see in our pipeline with some of our assets. But maybe, Kurt, you want to talk a little bit as well?

Kurt Gustafson

Yes, Puneet, I mean, I -- we don't have any specific knowledge relative to the sales forecast, if you will, of our partners. I know that one of our partners disclosed earlier this year that there have been supply chain issues in the first half of the year, in part due to challenges with COVID. But they also indicated that they expect that those supply chain issues will be alleviated in the second half of the year. And so they were forecasting sales to pick back up. And we obviously earn a royalty on that. I think the first part of your question, our partnerships are designed really to align sort of the economics that our partners pay with success, right? So I do think in a difficult -- if we're in a difficult funding environment, our model is conducive to have people continue to use it because they're really not paying -- they're not paying for -- or large sums of money until they actually have success, they discovering the drug and actually moving into the clinic. So I do think that there's opportunities there, and we're still continuing to see growth across our key metrics.

Operator

Your next question comes from Robyn Karnauskas from Truist Securities.

Robyn Karnauskas

I'm going to start off with a couple that I [don't know] you'll be able to answer. So can you talk a little bit about how the platform deals with Stanford and those are different than those of the pharmaceutical companies? Like how are they structured if you can give any color? And is your -- are your ion channel programs have -- do they have better economics given the scarcity of like being able to develop small molecules to those -- biologics to those programs? I would think that they have better economics since you're adding a lot more value.

Matthew Foehr

Yes, Robyn, thanks. I'll answer your second question first on the ion channel programs. And really, the short answer is yes. The way those programs are structured, we are granting exclusivity to the target -- to the specific target with that -- with those partners. They're accessing not only technology and capability, but novel cell lines, novel reagents, novel screening technologies, et cetera. So that then drives really a different and a higher economic structure. The 5 programs that are highlighted in the deck today for ion channel and transporter collaboration, both those are with GSK and with Roche, those 5 programs alone have $1 billion in milestones and royalties that are higher than our standard platform license agreements. So those are assets that we're excited about. Obviously, we highlighted the GSK program today. But the short answer is yes.

Now to your first question about the different sorts of deals. We have, in recent quarters, leaned into not only license agreements with leaders in the industry, commercial -- those that are investing a lot in R&D and commercialization like Merck and Neurocrine, but also with academic centers, leading academic centers. And just as a general matter of policy and based on confidentiality, we don't disclose specific deal structures, but we have -- and in our corporate deck, we've outlined typical deal terms for all of our deals. And they fall within boundaries that we previously disclosed. There are multiple parts of the deals, there are upfront payments, there are milestones, there are royalties and there's an interplay between those.

But in terms of access to the platform, there really are not major differences between the deals signed with, say, a traditional commercial pharma and the academic centers. But on the business side, obviously, it would be highly unusual for an academic center to commercialize the drug on its own. Obviously, these folks have leading-edge biology. They generally want to translate that into therapeutics that then get spun out into companies. So really, the only difference is we'll have special provisions with -- that specifically deal with how those economics will work when the academic institution chooses to out-license the program or form a company around it. But at a basic sense, they're very similar. There are just some specific provisions that are more applicable to the academic setting.

Robyn Karnauskas

That's really helpful. And I guess a follow-up, it's like $1 billion is a lot. So have you been able to negotiate since you've been working with these companies, a little bit more disclosure about what you need to see to get those milestones? And then my last question, sorry for so many. You don't talk a lot about OmniDeep, and I know you believe that nature-based [indiscernible], but I'm just wondering if you're willing to leverage OmniDeep platforms to AI/ML-based in silico antibody design. It's a hot topic right now, so I thought I'd ask that question.

Kurt Gustafson

On the first part, just financially, the way these deals are structured, they're really structured the same way as our other deals, right? So there are typically clinical stage milestones as they progress through the clinic and royalties. The difference is that the magnitude of the payments are larger and mostly because of a function of the exclusivity on which we have written these deals. On the antibody side, all of the things that people are going after, those are nonexclusive targets. Whereas with the ion channels, these targets are being licensed out on an exclusive basis. And as a result, that's what triggers the larger economics. But there's nothing unusual necessarily about the types of things they fall within that same sort of deal structure of upfront payment and milestones and royalties.

Matthew Foehr

Yes, and I'll be happy to comment on the AI question, Robyn. Obviously, given the visibility and use of AI associated with technologies or industries that are, I'll say, highly visible in a popular sense or counted in a popular sense. This is obviously a question we do get. And OmniDeep, I'll just say, is our suite of in silico tools for therapeutic antibody discovery and optimization that are really woven throughout our various technologies and capabilities. And these tools include the structural modeling and large -- very large multi-species antibody databases, AI and machine learning sequence models and more. And it really -- it allows for optimization of identification of candidates that come out of our technology.

Now there's -- to the core of your question, obviously, there's a lot of discussion around AI and its use -- kind of sole AI approaches. And I think the element of that, that might not be as well understood is that there are really some important considerations and limitations of that, and that's why we think there's so much power in not only the biological intelligence of our animals, but also the leveraging our AI capabilities. Now we've been using in silicon and AI tools in our downstream work for a long time actually, especially on the screening side and some of our work around the ion channels and transporters. So we have deep expertise here in our organization that we really kind of rolled out in the concept of OmniDeep in Q2, but these have been woven throughout our organization and technology from the spirit of cutting edge and good science for quite a long time.

And in fact, more than a couple of years ago, we actually did a deal with landing AI for a vision portion of AI that we incorporated into our exploration platform successfully that has really been kind of a wild success story around how we leverage our screening. But I'll say on the technical level, there's a lot of limitations to just AI approaches. So really the power of OmniDeep comes from marrying it to, what I'll call, the biological intelligence of our transgenic animals because a carefully engineered transgenic animal system really has many of the tests that are needed to select a winning antibody inherently built into them as natural checkpoints. So you can essentially try and test millions of different sequence possibilities rather than just doing it in a model. And obviously, the biological system can weave those out. Now we do leverage AI and other ways downstream from that with large amounts of data. And I think that's where a lot of that power comes from. So I know I got a little technical there, but hopefully, that makes sense.

Operator

Your next question comes from Stephen Willey from Stifel.

Stephen Willey

I appreciate some of the macro commentary that you provided. I know some of your peers have been kind of talking about that of late. But I guess, have you seen much in the way of any uptick of attrition just on the discovery program front? And would you expect that to be kind of the better surrogate of some of the macro challenges just given some of the reprioritization of R&D spend and, I guess, kind of broader pipeline streaming efforts that we're starting to see across the space?

Matthew Foehr

Yes. I mean, a great question, Steve. I'd say, really nothing specific there on the attrition front. As we noted, obviously, I'll just say at the outset, attrition is a natural part of the pharmaceutical industry, as we all know, many things fail, and that's -- the fact that there is attrition is obviously expected. This last quarter, we only saw attrition in the discovery phase and just in discovery stage assets. Looking back a little bit in the fourth quarter of last year, we saw first program attrition at the clinical stage, 2 partners had exited certain therapeutic areas or specific therapeutic areas, those assets themselves may have potential in other hands, but are not included in our program count anymore. I bring that up as an example. It's difficult to say. Is that a macro thing? Is that just larger partners focusing in those specific instances? It's very difficult to say. So I think it's hard to answer your question specifically, but these are all metrics that we always monitor all the time, and obviously, keep having deep dialogue with our partners. So hopefully, that gives you a little more color.

Stephen Willey

Okay. And I guess the work that's ongoing in the ion channel space, I know that these, again, are being kind of out-licensed on a target exclusive basis. But I guess, for those targets that have already been claimed by either GSK or Roche, and I understand that all of these are difficult to drug. But I guess, how would you kind of characterize these targets that they've selected in the hierarchy of things that are difficult to do within the ion channel space itself? And how much more kind of green space in the target universe do you think that you have over the next kind of 1, 3, 5 years?

Matthew Foehr

Yes. Great question, Steve. The description -- obviously, there's a substantial amount of confidentiality considerations and other things with partners that we always respect of course. But the GSK relationship is around specific targets for neurological disorders. And at the discovery phase, it was an agreement that was originally struck a couple of years ago, so it's progressed well. Obviously, we announced the milestone in this quarter. And I'll just say when folks are pursuing ion channels and transporters, these are generally considered high-value targets, right?

And I'll just comment generally. I think GSK has a really ambitious innovation agenda in this area. They stated publicly a goal to positively impact the health of 2.5 billion people by the end of 2030. So that's a really aggressive goal and an ambitious one, and we're excited to be collaborating with them. I think these are our programs where we've got distinct capabilities and cell lines and reagents and other things as well as high-throughput screening as well as the ability to leverage multiple modalities, which I think are the kinds of things that can attract more of these sorts of partnerships potentially in the future.

Operator

Your next question comes from Matt Hewitt from Craig-Hallum.

Jack Siedow

This is Jack on for Matt. Obviously, you've recently just launched OmniDeep, and I was just kind of curious what the initial reception has been for your customers?

Matthew Foehr

Yes. Thanks, Jack. I'll say, very positive. We launched it at the PEGS Conference in Boston in May. And I'll say that the feedback in the room is a big area, a big presentation, very well attended, and the feedback from partners who were sitting in the room was almost immediate. And it continues to be an area of focus in terms of not only new programs, but potentially taking different approaches to increase the potential success rate of some existing programs with partners and our -- obviously, our research and innovation team and our BD team continues to partner on that as we talk with partners about it. So the feedback has been quite positive.

Operator

Your next question comes from Chad Wiatrowski from TD Cowen.

Matt, Kurt, it's Chad on for Steven Mah. Yes, congrats on the GSK milestone. Could you give us some more detail as to what differentiates your tech stack from peers who also claim at these historically difficult targets such as ion channels or an opportunity that they're pursuing as well?

Matthew Foehr

Yes, sure. Happy to talk more about it. I think one of the -- a few things differentiate our technology, right? At the core is the foundation of the multi-species approach that we can present. But beyond that, we highlighted a little bit about our commitment to continually expanding our capabilities around the ion channel space. We have a long history here that really date back decades in terms of building high-throughput screening that can be applicable to a variety of modalities, I think that is extremely important in this space where -- and especially in the industry overall, where the lines between different approaches and modalities are becoming creatively blurred intentionally. And I think we are really at a spot where we can leverage that different than others.

We've also built up an extensive bank of custom cell lines that are specifically designed to facilitate the discovery in these areas -- in some of these specific areas. That's something that's been built up over many years. And when you marry that with our other discovery and repertoire generation and screening technologies, it really does, I think, position us in a pretty unique fashion. And I think that's why folks like GSK and Roche are attractive to us for these sorts of partnerships.

Chad Wiatrowski

Really helpful. And I appreciate the improved downstream economics regarding ion channels, but there's sort of precedent that exclusivity of targets has led to some significant upfront payments. So is there an opportunity here to drive some upside in the near-term?

Kurt Gustafson

All deals are become a negotiation, right? And so I think to the extent that we show success that we always try to leverage that for higher payments. I think as we look historically, a lot of this -- the difference between this and the antibody business has been more just on the exclusivity. The other thing that I would point out on the ion channel side and Matt talked a little bit about the expertise that we have. And so for the most part, with these ion channel programs, there's a license that for a target on an exclusive basis, but then we are continuing to do all of that work.

And so a big portion of the service revenue that we generate comes from the ion channel side of the business. In many cases, the partners are pre-paying for that and sort of gave the example today on the specific GSK program where they paid $7 million upfront that was being amortized over the research period. So we are able to generate relative to the antibody side of that business, call it, outsized economics just on a relative basis. But a lot of that is just this function of that it's on an exclusive basis.

[Operator Instructions] Your next question comes from Yuan Zhi from B. Riley.

Brandon Carney

This is Brandon Carney on for Yuan. You talked some about the trends you've been seeing in the discovery stage. Can you comment on the clinical stage regarding delays or cancellations of clinical trials? Can you comment on what you've observed so far related to the projects you're tracking the biologics to build them?

Matthew Foehr

Yes. This is Matt. I'll comment and Kurt have some comments here. When we started the year, we said we expected 3 to 5 new clinical entrants this year. At the end of Q2, we were actually already at 3. And today, we're focused now on a higher area there of 4 to 5 this year. And so we're seeing nice clinical progression or graduation into the clinical stage. We are pleased this quarter to see some assets move out of discovery into preclinical, which means that they're then preparing to enter the clinic. So we are seeing nice progression in the portfolio. I don't know, if, Kurt, anything you'd want to add to that?

Kurt Gustafson

We have not actually seen a lot of clinical attrition in terms of the clinical attrition that we have seen, it's really not -- it's been a function of partners exiting therapeutic areas as opposed to sort of any failure of a study or something like that. As Matt said, attrition is part of this business, and it will happen. But our experience thus far on the clinical side has actually been pretty darn good relative to industry averages.

Brandon Carney

That's helpful. And one last one from us. Have you noticed any shifted interest in biologics development due to the Inflation Reduction Act?

Kurt Gustafson

I mean, I'll just make a comment. I mean, our business is mostly on the antibody business -- on the antibody side. So it is probably a more attractive place to develop drugs just given the benefits that have been afforded by the Inflation Reduction Act. But given that we -- if we had a small molecule offering and an antibody's offering, would we see more people moving over the antibody? I don't know. It's tough to say. We believe that we've got a great platform, and we're continuing to attract new players as evidenced by the 4 new deals that we signed this quarter. So Matt, I don't know if you have?

Matthew Foehr

Yes. I think -- I mean, I'd add that because of the higher success rates of antibody-based medicine as compared to small molecules, from a scientific and technical perspective, there've been an evolving shift in the industry because of those higher success rates. So that's something obviously we see and hear and know. Now, the IRA, obviously, the legislation will allow Medicare to negotiate drug prices with manufacturers for a select number of high-cost drugs starting, I believe, in 2026, and there are exceptions to how all those negotiations can happen and that sort of thing. But there are, I'll say, a longer tail that's afforded to biologics medicines, which is something that may accelerate the interest in the industry and a shift towards biologic medicines that we saw happening already in advance of IRA.

So I think if anything, it can help accelerate the interest there. But I think the science and the probability of success in medical benefit in terms of the specificity that antibody-based medicines provide and predictability for development was already starting that shift. So if anything, it just may accelerate it.

There are no further questions at this time. I will turn the call back over to the CEO, Matt Foehr.

Matthew Foehr

Great. Thank you. I'd like to thank everyone for participating in today's call and for your questions. We look forward to keeping you updated on our progress and speaking with you next quarter and at various investment conferences we'll be attending in the coming weeks and in the fall. We'll be at the Stifel Conference coming up. We'll also be at H.C. Wainwright, Cantor as well as the Craig-Hallum Capital Conferences in New York in the fall. So in the meantime, we appreciate your interest in OmniAb, and thanks again. Have a great day.

Operator

Ladies and gentlemen, this concludes your conference call for today. We thank you for joining, and you may now disconnect your lines.
