Presentation

[Operator]

Good afternoon, everyone. Thank you for standing by. Welcome to the Corvus Pharmaceuticals Second Quarter 2026 Business Update and Financial Results Conference Call. At this time, all participants are in listen-only mode. Later, we will conduct a question-and-answer session. Instructions will follow at that time. It is now my pleasure to turn the call over to Zack Kubow of Real Chemistry. Please go ahead, sir.

[Zack Kubow, Senior Group Director, Investor Relations at Real Chemistry]

Thank you, operator. Good afternoon, everyone. Thanks for joining us for the Corvus Pharmaceuticals Second Quarter 2026 Business Update and Financial Results Conference Call. On the call to discuss the results and business updates are Richard Miller, Chief Executive Officer, Leiv Lea, Chief Financial Officer, Jeff Arcara, Chief Business Officer, and Ben Jones, Senior Vice President of Pharmaceutical Development. The executive team will open the call with some prepared remarks, followed by a question-and-answer period. I would like to remind everyone that comments made by management today and answers to questions will include forward-looking statements.

[Zack Kubow, Senior Group Director, Investor Relations at Real Chemistry]

Forward-looking statements are based on estimates and assumptions as of today and are subject to risks and uncertainties that may cause actual results to differ materially from those expressed or implied by those statements, including the risks and uncertainties described in Corvus's annual report, quarterly report on Form 10-Q for the quarter ended June 30, 2026, and other filings the company makes with the SEC from time to time. The company undertakes no obligation to publicly update or revise any forward-looking statements, except as required by law. With that, I'd like to turn the call over to Leiv Lea. Leiv?

[Leiv Lea, CFO at Corvus Pharmaceuticals]

Thank you, Zack. I will begin with a brief overview of our second quarter 2026 financials. Then turn the call over to Richard for a business update. Research and Development expenses in the second quarter of 2026 total $16 million, compared to $7.9 million for the same period in 2025. The increase in R&D expenses was primarily due to higher clinical trial costs associated with the development of soquelitinib, as well as an increase in personnel costs. Net loss for the second quarter 2026 was $18 million, compared to a net loss of $8 million for the same period in 2025.

[Leiv Lea, CFO at Corvus Pharmaceuticals]

Included in the net loss for the second quarter of 2026 and 2025 were non-cash losses of $0.7 million and $0.4 million, respectively, from Corvus's equity method investment in Angel Pharmaceuticals, and a non-cash gain of $2 million in the second quarter of 2025 associated with a change in fair value of the company's warrant liability. Total stock compensation expense for the three months ended June 30th 2026 was $2.6 million, compared to $1.3 million for the same period in 2025. As of June 30th 2026, Corvus had cash equivalents, and marketable securities totaling $215.2 million as compared to $56.8 million at December 31st 2025. Cash as of June 30th 2026 included approximately $189.4 million in net proceeds received in a follow-on offering completed in Q1.

[Leiv Lea, CFO at Corvus Pharmaceuticals]

As announced on June 9th 2026, Corvus invested $5 million in a $13.5 million financing completed by Angel Pharmaceuticals in the second quarter of 2026. Based on our cash position at June 30th 2026 and our current plans, we expect our cash to fund operations into the second quarter of 2028. I will now turn the call over to Richard, who will discuss our clinical progress and elaborate on our strategy and plans.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Thank you, Leiv, and good afternoon, everyone. Thank you for joining us today for our update call. We are highly focused on soquelitinib, our first-in-class selective ITK inhibitor. Our efforts are primarily directed to driving patient enrollment and executing on our clinical trials to reach the next milestones for soquelitinib's two lead opportunities. Our phase III peripheral T-cell lymphoma program, or PTCL, and our phase II atopic dermatitis program. In parallel, we continue to advance soquelitinib's development across broad areas of medicine, including near-term plans to initiate trials in hidradenitis suppurativa and asthma, as well as the ongoing trial at the NIAID in ALPS. The growing body of clinical and pre-clinical evidence supports the broad potential of soquelitinib based on its novel mechanism of action and ability to reset or rebalance immunity.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Our ongoing development efforts with soquelitinib position Corvus to deliver key data readouts and milestones associated with our pipeline over the next year. I will start with a brief update on our phase III trial in relapsed refractory PTCL, which is planned to enroll 150 patients randomized one-to-one between soquelitinib and standard of care chemotherapy with belinostat or pralatrexate. The primary endpoint is progression-free survival, or PFS, which with current treatment options, has a median of about three months. Enrollment is on track with our expectations, with the next milestone being a futility analysis that will be conducted after a predefined number of PFS events have occurred. Based on current trends, we believe this interim futility analysis will occur in the first quarter of 2027.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

The futility analysis will be conducted by an independent data monitoring committee that will determine whether the study should be continued or terminated for futility based on available safety and efficacy data at the time. No safety or efficacy data will be publicly released at that time. We remain excited about the potential of soquelitinib to provide a new treatment option for patients with relapsed refractory PTCL, particularly given the challenges with current therapies, none of which are fully approved for this indication. I should also mention that the results of our phase I trial are now in press in "Blood," the peer-reviewed medical journal of the American Society of Hematology. We expect the results will be published later this year, providing an important overview of soquelitinib's mechanism of action, rationale, and data obtained from the phase I trial.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Some of this data was presented at the ASH meeting last year. Turning to our other high-priority indications for soquelitinib atopic dermatitis. We remain very excited about the data to date and our path forward in this indication. During the second quarter, we presented the final data from the randomized, blinded, placebo-controlled phase I trial evaluating soquelitinib in patients with moderate to severe atopic dermatitis at the Society for Investigative Dermatology, or SID Annual Meeting. The data demonstrated safety and positive efficacy results, including 75% of soquelitinib patients achieving EASI-75 in Cohort 4, compared to 20% of placebo patients. Cohort 4 studied is the highest dose and longest dosing period tested in the trial, covering 24 patients randomized in a one-to-one ratio to receive 56-day, eight weeks, 200 mg twice a day daily regimen of soquelitinib or equivalent placebo.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

In addition to the compelling EASI-75 result, 25% of soquelitinib patients in Cohort 4 achieved EASI-90, and 33% achieved an IGA 0 or 1. No patients receiving placebo achieved EASI-90 or IGA 0/1. Importantly, soquelitinib's efficacy results were observed in patients who received prior systemic therapy, some of whom were confirmed to be treatment-resistant to these systemic therapies. The data also showed a dose-dependent efficacy trend and additional clinical benefit with longer treatment. Of significant interest was the observation of prolonged treatment benefit extending beyond the period of dosing without evidence of disease rebound. Disease rebound has been observed with other agents, including dupilumab, JAK inhibitors, and STAT6 degraders and inhibitors. The finding of soquelitinib's durable activity was not surprising given research done by Corvus and others demonstrating that ITK blockade results in enhancement of T regulatory function.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

In the SID presentations, we presented compelling data correlating the induction of Tregs with prolonged clinical responses. If confirmed in future studies, these findings may usher in a new treatment paradigm for autoimmunity, resetting or rebalancing of immunity. On the safety front, no significant safety issues were observed. No severe or serious adverse events were reported, and no significant lab abnormalities were seen. There was no conjunctivitis and, of course, no injection site problems since it is an oral drug. There was no difference in adverse events seen comparing placebo to the active groups. All of this is in line with our experience with soquelitinib in lymphoma patients, some of whom are on continuous drug for over two years.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Based on its novel mechanism of action, oral dosing, and the safety and efficacy data to date, we believe soquelitinib could become a leading therapy for atopic dermatitis that may find a valuable role in frontline therapy or treatment of relapsed refractory disease. Our strategy is to progress soquelitinib as quickly as possible through the typical development pathway, similar to the other approved systemic therapies for atopic dermatitis. This includes our phase II trial, the SIERRA-1 trial, which is currently enrolling patients, followed by the usual phase III trials. These trials will have a primary endpoint based on EASI score and IGA score at 12 or 16 weeks of therapy compared to placebo. Our goal is to make soquelitinib available as soon as possible for patients, and then expand the clinical evidence and label with post-marketing studies exploring some of its more unique attributes.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

The phase II SIERRA trial is planned to enroll approximately 200 patients with moderate to severe atopic dermatitis that have failed at least one prior topical or systemic therapy. It is double-blind, randomized, that includes four cohorts of 50 patients each with soquelitinib doses of 200 mg once per day, 200 mg twice per day, and 400 mg once per day, along with a placebo group. The treatment period is 12 weeks with a 90-day follow-up period with no treatment. The primary endpoint is reduction in mean EASI score at 12 weeks compared to the placebo. There is no OLE, or open-label extension, because we believe there will be durability of remissions that we do not want to obscure with additional treatment. Our OLE is no treatment.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Enrollment and site activations are on track with our plans, with anticipated enrollment completion in early 2027 and top-line data in the third quarter 2027. In parallel, we are working in close collaboration with our partner in China, Angel Pharmaceuticals, on their phase Ib/II clinical trial of soquelitinib in moderate to severe atopic dermatitis. The Angel trial has similar design to our phase II trial. It is blinded, placebo-controlled, and is evaluating a 12-week treatment regimen and 90-day follow-up period across a similar range of soquelitinib doses. Cohort 1 includes 24 patients randomized evenly to soquelitinib doses of 100 mg twice per day, 200 mg once per day, or placebo. Cohort 2 will include 24 patients randomized evenly to soquelitinib doses of 200 mg twice per day, 400 mg once per day, or placebo.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Depending on the results from these 48 patients in Cohorts 1 and 2, an additional 60-90 patients are anticipated to be enrolled in the phase II portion of the study. The trial is open at several leading dermatology centers in China who have been involved in many global registration trials. We anticipate that Angel will complete patient enrollment from the first cohort in September, and data from the first cohort of the trial will be available before year-end 2026. The soquelitinib doses studied in this cohort are the same as the lower dose level studied in our phase I trial, 200 mg total per day, taken as either 100 mg tablet twice per day or 200 mg once per day. The treatment period, however, is significantly longer at 12 weeks compared to the four-week period studied for these doses in our phase I trial.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Recall, we found evidence of efficacy at these lower doses in our phase I trial with four weeks of therapy. Angel is evaluating these doses in a 12-week dosing regimen. We anticipate that data from the Cohort 2 will be available in the second quarter of 2027. Just to reiterate the timelines for Angel, we expect they'll complete enrollment of the first cohort in September, data from this cohort by the end of this year, data from the second cohort in Q2 2027. With the Angel data, together with our own data that will be generated during the year of 2027, we could be in a position to start a phase III trial by the end of the year in 2027. In addition to providing clinical data supporting the value of soquelitinib in atopic dermatitis, there is another important strategic feature to the Angel trial.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

It is widely reported in the literature that Asian patients with atopic dermatitis have a greater component of TH17 disease and don't respond as well to IL-4 and IL-13-targeted treatments like dupilumab, which is designed to treat TH2 disease and does not affect TH17. Based on mechanism of action with ITK inhibition, which decreases both TH2 and TH17 cell function and their downstream cytokines, we think this positions soquelitinib well for this population. Finding results in these types of patients may serve to broaden and confirm the potential utility in TH17 diseases. An example of the importance of Angel to Corvus is our participation in Angel's recent $13.5 million financing. Corvus is a founder of Angel and continues to be its largest shareholder with $5 million invested in this new financing.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

The funding is anticipated to support Angel's ongoing phase Ib/II trial of soquelitinib for atopic dermatitis and a new phase II trial of soquelitinib for asthma that is expected to start in early 2027. We believe Corvus is positioned to benefit from both of these trials, which will contribute to the overall data set for soquelitinib in these indications and enhance the opportunity for ITK inhibition in the large Chinese inflammation and immunology market. I am the CEO and Chairman of Angel, and I must add that it has been a privilege and delight to work with the very talented team in China. In the U.S., Corvus remains on track to initiate our own phase II asthma trial later this year, along with a phase Ib proof of concept trial in patients with HS, hidradenitis suppurativa.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Our plan to expand the soquelitinib pipeline into these indications is aligned with the biology of ITK inhibition. We started with TH2 cells in T-cell lymphoma and then moved to atopic dermatitis, which is primarily driven by TH2 cells. Next, we are moving to hidradenitis suppurativa, which is primarily driven by TH17 cells, and then into asthma, which is primarily driven by TH2 cells, but in certain types dominated by TH17 cells. There is an important strategy to our clinical programs. With each program designed to not only address an important clinical indication, but also to provide data supporting soquelitinib's mechanism of action and potential utility across a spectrum of underlying drivers of disease. For the phase Ib hidradenitis suppurativa trial, we currently anticipate the trial will enroll up to 25 patients with moderate to severe disease. There will be no placebo group.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

All patients will receive the same dose of soquelitinib for 12 weeks, 200 mg BID. In addition to measuring safety and the standard hidradenitis suppurativa clinical response score, we're also planning to include intensive monitoring of skin and blood biomarkers, looking for TH17 effects. We plan to start this study in September. The potential broad utility of soquelitinib is an important factor in the design of our planned asthma study. We intend to enroll both the allergic or eosinophilic and non-allergic types of asthma. You may also hear these referred to as T2 and non-T2. Most asthma drugs and most clinical trials address only the allergic T2 patients. We intend to enroll both types based on our mechanism of action, which we believe will address both T2 and non-T2 disease. Approximately 40%-50% of asthma patients have the non-T2 type. It is a very substantial proportion of asthma patients.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

This doubles the potential population of patients. The trial design will include an interim analysis, which will allow us to discontinue a disease type, such as T2 or non-T2, if there is futility. We remain excited about soquelitinib's potential to modulate several key cellular functions that are not currently targeted by approved and in-development stage biologic therapies with an oral tablet. At the SID meeting, Stanford professors Chu and Saran presented new immunologic and biomarker data that showed the potential of ITK inhibition with soquelitinib to increase persistent Treg cells and influence multiple inflammatory pathways. These data support the potential for soquelitinib to reset or rebalance the immune system and treat a range of autoimmune and inflammatory diseases. Longer term, it also raises the very intriguing potential to produce drug-free remissions, a long-sought goal.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

In closing, our confidence in soquelitinib continues to grow. We are making good progress with our key priorities to unlock the opportunity to help a broad range of patients with ITK inhibition. Over the remainder of the year, we are focused on, first, driving enrollment in our soquelitinib phase III registration PTCL trial and our phase II atopic dermatitis trial. Second, coordinating closely with our partner in China, Angel Pharmaceuticals, on their phase Ib/II atopic dermatitis trial with data from the first cohort before year-end and data from the second cohort in the second quarter of 2027. Third, advancing the broader soquelitinib opportunity with the planned initiation of trials for asthma and hidradenitis suppurativa before year-end.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

As we achieve these milestones, we believe there will be increased appreciation for the potential of ITK inhibition and immunomodulation, which could lead to new and better therapies for inflammatory, autoimmune, fibrotic diseases, and cancers. I will now turn the call over to the operator for the question-and-answer period. Operator?

[Operator]

Thank you. Ladies and gentlemen, we will now begin the question-and-answer session. If you have a question, please press star followed by the number one on your touch tone phone, and you will hear a prompt that your hand has been raised. If you wish to decline from the polling process, please press the star followed by the number two. One moment please for your first question. Your first question comes from the line of Jeff Jones of Oppenheimer. Your line is now open.

[Jeff Jones, Analyst at Oppenheimer]

Hi, guys. Can you hear me?

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Yes. Hear you fine.

[Jeff Jones, Analyst at Oppenheimer]

Great. Hi, Richard, and congrats on all the progress and continued progress for this program. On the topic of drug-free remissions, have you had any discussions with the agency about the potential for drug-free remissions and how you would generate a claim on the label and what study design could look like?

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Jeff, everything we're doing now, the design is straightforward. We compare soquelitinib to placebo, EASI scores, EASI-75s, IGAs at 12 or 16 weeks. Same as everybody else. That's what's required. Those are our protocols. What we do in the remission periods or drug-free periods, just like everybody else, dupilumab, JAK inhibitors, they continue to treat some patients, or some they allocated to placebos, to determine whether or not there was disease rebound, and there almost always is. Therefore, they determined that the maintenance therapies were required for those diseases. Those were not part of the original approvals. That is not necessary to do that. We think it's very important if we have sustained remissions that don't require a drug.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

That represents an amazing opportunity and unique advantage for soquelitinib. That is not part of the regulatory strategy. Later, should you want to be able to re-treat patients, of course, you would do additional trials to confirm that. Does that make sense?

[Jeff Jones, Analyst at Oppenheimer]

Great. Yep, makes perfect sense. Then just one follow-up. Obviously, top dose appears to be 200 mg BID right now. Are you guys doing any work to look at extended-release formulations?

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

We do have work going on in the company looking at other formulations. We also have a lot of work going on in terms of other ITK inhibitors, other chemical structures, et cetera. I think that we're going to end up here probably with a regimen that's once-a-day dosing, because I think as we treat patients longer than four weeks, there will be very suitable efficacy with a once-a-day dosing regimen. We're looking at various regimens. As you know, in our cancer study, we went up to 600 mg BID. We know that a single dose of 200 mg will completely saturate the ITK target.

[Jeff Jones, Analyst at Oppenheimer]

Great. Thank you very much, Richard. Congrats again on all the progress.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Thank you.

[Operator]

Your next question comes from the line of Graig Suvannavejh of Mizuho. Please go ahead.

[Salim Syed, Analyst at Mizuho]

Hi, this is Salim on for Graig. Thanks for taking our question, and congrats on the progress, team. Maybe just on the PTCL. It seems that there was a delay in the potential interim readout by a quarter. I'm just curious what the considerations were there and do you guys still anticipate the phase III data by the end of next year or is that more of a 2028 story now? Thanks.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

We anticipate the final data late 2027, as originally stated. The interim analysis, of course, is projected based on events. It's hard to say exactly when they occur, because it's based on number of events, according to our statistical plan and agreement with FDA. Based on event rates, we're now projecting early in 2027. That could change a little bit depending on the number of events that occur.

[Salim Syed, Analyst at Mizuho]

Very helpful. Thanks so much, Richard.

[Operator]

Your next question comes from the line of Paul Choi of Goldman Sachs. Please go ahead.

[Erik Wong, Analyst at Goldman Sachs]

Hi, this is Erik on for Paul. Thanks for taking the question. I have a quick question. Are you able to use the Angel partner data as part of the safety database for further FDA filings? Are you assuming incrementally better efficacy in the Chinese population for AD? What are your thoughts, or can you provide us some color on what your thoughts are on how you expect efficacy to change in the Chinese population?

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Yes, we can use the Chinese safety and efficacy data in our regulatory filings, and vice versa. They can use our data in their filings. That's one of the reasons we initiated this collaboration several years ago. The idea behind it was accelerated and extend our capabilities and leverage the Chinese population and regulatory authorities and clinical trial infrastructure, all that. Yes, the data can be shared. The second part of your question is, do I expect comparable data from Angel? It is a different study. It's an entirely different clinical trial done at a different point in time at different institutions. Hard to predict exactly. Theoretically, I think that we could beat the placebo by more because we have this combined effect on the TH17/TH2.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

One might expect, let's say, compared to other treatments, a better effect. It's going to be hard to compare across clinical trials and across the Pacific Ocean. The Chinese trials are being done at, I think there's around 10 centers now. They're very good, well-known, academic, large hospital and dermatology clinics. They're commonly sites for large pharma and many other agents in dermatology and atopic dermatitis in particular. We feel very good about the quality and the information we're going to get out of there.

[Erik Wong, Analyst at Goldman Sachs]

All right. Really helpful. Thanks.

[Operator]

Your next question comes from the line of Cha Cha Yang of Jefferies. Please go ahead.

[Cha Cha Yang, Analyst at Jefferies]

Hi, this is Cha Cha on for Roger. Thanks for taking my question here. I have two. One is, can you just tell us more about the thought process behind doing a 12-week versus the 16-week trial for AD for your phase II? My second question is, you may have touched on this, I may have missed it, but can you just tell us more about the trial design and some of the baseline characteristics for your HS and asthma trials? Thanks.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

We have looked at four weeks of we looked initially at four weeks of dosing, then went to eight, and now we're doing 12 weeks of dosing. We saw very good efficacy at four weeks with 200 mg BID. We saw very good efficacy at eight weeks with curves continuing to go down. We'll look at the 12-week data that we get both from Angel and from what we're doing in our phase II, and we'll make a decision beyond that. I know that there's a lot of questions like 16 weeks is magic. It isn't. In our view, if you can get excellent efficacy with a shorter dosing regimen, why wouldn't you do that? Now eventually, if we see the curves continuing to go down, we will go to 16 weeks. I don't see any reason to do that now.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

We've had some of our dermatology experts tell us that, "Gee, your results at four weeks are as good as what you're seeing at 16 weeks." By the way, I would go back and look at the publications on dupilumab and JAK inhibitors, and you'll see 12 and 16 weeks of treatment. Guess what? Those curves plateau at around six or eight weeks. Most of the efficacy in these 12 and 16-week regimens, go back and look at the EASI curves. Most of the efficacy is seen in the first couple of months. After that, the changes are really pretty small. Okay. Was there another part of your question? Can you-

[Cha Cha Yang, Analyst at Jefferies]

Yeah. Just about trial design and baseline characteristics for your HS and asthma trials.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Moderate to severe HS, moderate to severe asthma. The asthma trial in particular, that's worth talking about. As you know, most studies are allergic or T2, and they'll frequently use an eosinophil count of 300 or 150 above 300 or above 150, that's changing these days, as an eligibility requirement. We're allowing both T2 and non-T2. That is, we'll take patients above 150 and below 150 eosinophils. Now, we have looked at our AD data with respect to eosinophil count. We have patients who are above 150 and patients who are below, and in terms of the efficacy, we see basically equal efficacy in both groups.

[Cha Cha Yang, Analyst at Jefferies]

Okay. Thank you

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

I think we're starting to now talk about what are the potential advantages of our novel mechanism of action. Well, the non-T2 asthma, if you look at their lungs, you don't see TH2 cells. You see a lot of neutrophils, you see other inflammatory cells that are induced by TH17 cells. TH17 cells make neutrophil attractant things like GM-CSF and things like that. We've seen in our animal models that we can affect that. Of course, mechanistically, we know we're blocking the differentiation of the TH17 cell. The major eligibility there is the eosinophil count. Now, of course, we look at pheno and other things, but that's the major thing. All right.

[Cha Cha Yang, Analyst at Jefferies]

Thank you.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Thanks.

[Operator]

Your next question comes from the line of Li Watsek of Cantor Fitzgerald. Please go ahead.

[Analyst at Cantor Fitzgerald]

Hi, this is Mubina on for Li. One question about your asthma program. You said that you're targeting both the T2 and the non-T2 as well. Can you explain mechanistically why you think soquelitinib would be able to work in both T2 and non-T2 as well? Thank you.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Well, the reason it's called T2, because it's TH2 mediated, and of course, as we've mentioned previously, we'll block the differentiation of TH2 cells and the resulting cytokines. The TH2 is sort of obvious. The non-T2 is TH17. Mostly you see TH17 cells and other inflammatory cells. The other inflammatory cells are induced by these TH17 cells. Since we blocked the differentiation of activated TH2 and TH17 cells, we would expect to see activity in both T2 and non-T2. There's another important cell involved in both of these, T2 and non-T, which is called the innate lymphoid cell type 2. Highest expression of ITK of any lymphocyte, and we know we inhibit that very well also. There are many reasons to think that we would affect the non-T2, and this represents a great opportunity for us to test this in the clinic.

Of course, provides a unique advantage over other asthma treatments.

[Analyst at Cantor Fitzgerald]

Thank you. That's helpful.

Your next question comes from the line of Kevin DeGeeter of Ladenburg. Please go ahead.

[Kevin DeGeeter, Analyst at Ladenburg]

Great. Thanks for taking our questions. I also have a question on the asthma program, specifically, the planned Angel Pharma phase II program. Can you just comment a little bit more about potential study design there and how the learning from that study will be incorporated into the global program? Thank you.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Sorry, you're asking about the Angel AD study or?

[Kevin DeGeeter, Analyst at Ladenburg]

Oh, correct. Yes.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Well, I'm not sure I'm.

[Kevin DeGeeter, Analyst at Ladenburg]

I know. The Angel asthma study. The Angel asthma study.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Okay. Yeah. The current plan is for the Angel trial to basically be identical to ours. Our current plan is to run two identical phase II trials. It'll be essentially the same protocols in both places, but run independently.

[Kevin DeGeeter, Analyst at Ladenburg]

Great. On those protocols, can you just help us better understand the decision tree with regard to the ability to drop either T2 or non-T2? Is it a certain number of patients that will go into that assessment? Yeah, just a little bit more on that part of the study design. Thank you.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

Yes. Actually, we're going to base it on the percentage of the trial patients treated. At that time, we'll look at the data. We've written that part of it sort of with broad criteria. The success in non-T2 is different than T2. The bar for efficacy is lower. It's harder to treat. We have general guidelines now. After a certain number of patients are treated, if we don't meet a certain threshold in the T2 or the non-T2, we can drop either one of those, or we can drop them all. The reason we're doing that is because let's just say it's not working in the non-T2, we wouldn't want to continue and dilute out the effect, let's say, positive effect on the T2. Make sense?

[Kevin DeGeeter, Analyst at Ladenburg]

It does. Thank you very much.

[Operator]

There are no further questions at this time. I would like to turn the call back to Zack for the closing remarks.

[Richard Miller, President and CEO at Corvus Pharmaceuticals]

All right. Thank you, operator. First of all, thank you everyone for joining us today. We're very busy here at Corvus. The team, which I might add, has a lot of experience in conducting randomized trials, is working very hard now, meeting the goals I've outlined. We look forward to keeping you updated as we move through the rest of this year and next year. Thank you very much.

[Operator]

Ladies and gentlemen, this concludes today's conference call. Thank you everyone for your participation. You may now disconnect.
