Presentation

[Operator]

Greetings and welcome to Rigel Pharmaceuticals Financial Conference Call for the Second Quarter twenty twenty five. At this time, all participants are in a listen only mode. A brief question and answer session will follow the formal presentation. As a reminder, this conference is being recorded. It is now my pleasure to introduce our first speaker, Ray Furey, Rigel's Executive Vice President, General Counsel and Corporate Secretary. Thank you, Mr. Furey. You may begin.

[Raymond Furey, EVP, General Counsel & Corporate Secretary at Rigel Pharmaceuticals]

Welcome to our second quarter twenty twenty five financial results and business update conference call. The financial press release for the second quarter twenty twenty five was issued a short while ago and can be viewed along with the slides for this presentation in the News and Events section of our Investor Relations site on risel.com. As a reminder, during today's call, we may make forward looking statements regarding our financial outlook and our plans and timing for regulatory and product development. These statements are subject to risks and uncertainties that may cause actual results to differ from those forecasted. A description of these risks can be found in our most recent annual report on Form 10 ks for the year ended 12/31/2024 and subsequent filings with the SEC, including our Q2 quarterly report on Form 10 Q on file with the SEC.

[Raymond Furey, EVP, General Counsel & Corporate Secretary at Rigel Pharmaceuticals]

Any forward looking statements are made only as of today's date and we undertake no obligation to update these forward looking statements to reflect subsequent events or circumstances. At this time, I'd like to turn the call over to our President and Chief Executive Officer, Raul Rodriguez. Raul?

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

Thank you,

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

Ray, and thank you everyone for joining us today. Also with me today are Dave Santos, our Chief Commercial Officer Lisa Roiker, our Chief Medical Officer and Dean Schorno, our Chief Financial Officer. Beginning on Slide four, I will provide an overview of Rigel's accomplishments across the business and our financial results for the 2025. Let me start by saying that this was a really great quarter for Rigel. We continue to make significant progress on the execution of our corporate strategy.

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

For those not familiar with Rigel, our focus is on growing our hematology and oncology business through commercial execution, advancing our pipeline, product and licensing and acquisition and financial discipline. With this in mind, in the second quarter, we achieved net product sales of more than $58,000,000 an increase of 76% year over year and our best quarter ever. This all time high was driven by our growing commercial portfolio and increased sales across all our commercial products. Dave will provide a more detailed update on our three products and their second quarter contributions later on in the call. Total revenue for the second quarter was $101,700,000 including $42,700,000 in contract revenues from collaborations.

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

As I discussed during our May call, we notified Lilly that we would not exercise our right to share in future development expenses for okaducerptib, Rigel's RIPK1 inhibitor previously known as R552. As a result, we recognized $40,000,000 in non cash revenue in the second quarter. Dean will discuss the accounting of this in his remarks. Now let's talk about our development opportunities. We are excited about the potential of our development pipeline and our ability to fund the clinical development of R289 and olicitabine.

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

R289, our novel and selective dual IRAK1 and four inhibitor, is currently being evaluated in a Phase Ib clinical study in patients with relapsed or refractory lower risk MDS. We completed enrollment in the dose escalation part of this study in July, and expect to share updated data from the study later on this year. Lisa will walk us through the latest updates on our development pipeline. While we're focused on our internal development, we're also excited about the potential of vocadersertib, an important oral and selective inhibitor of RIPK1, and Lilly's efforts to advance this molecule. In parallel with growing our commercial business and expanding our development pipeline, we remain committed to pursuing additional in licensing deals or acquisitions of assets that fit our capabilities commercially and our product focus, such as we've already done successfully with both Brasilia and GAVRETO.

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

Underscoring this effort is an emphasis on maintaining financial discipline, while making the clinical development investments. This has resulted in both top line and bottom line growth and allowed us to generate $59,600,000 in net income and to increase our cash balance to more than $108,000,000 in the second quarter. Moving on to Slide five, you'll see the growth of our net product sales year over year. We have consistently delivered top line growth, as evidenced by the 32% compound annual growth rate or CAGR from 2021 to 2024. Year to date, in 2025, we have generated $102,500,000 in net product sales.

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

This is nearly the same net sales that we generated for the full year of 2023, and so a tremendous start to this year. We are now raising our total revenue guidance in 2025 to between $270,000,000 and $280,000,000 from the previous range of 200,000,000 and $210,000,000 which includes net product sales of $2.10 to $220,000,000 an increase from the prior range of $185,000,000 to $192,000,000 This new outlook reflects anticipated growth of 45 to 52% compared to 2024, exceeding the roughly 30% growth rate that we delivered over the last few years. Rigel is in a unique position as a self sustaining company with the added benefit of a promising pipeline of assets. We remain focused on the execution of our corporate strategy and continuing our progress throughout 2025 and beyond. Now with that, I will turn the call over to Dave to provide more information on our commercial business for you. Dave?

[David Santos, EVP & Chief Commercial Officer at Rigel Pharmaceuticals]

Thank you, Raul. On Slide seven, you'll see our three commercial products, TAVALISSE, GAVRETO and RESLIDIA. Moving to Slide eight, we are thrilled to report another excellent quarter from our commercial portfolio, marked by strong year over year growth and an all time high in revenues in the 2025. You can see on the slide how our quarterly and annual net product sales have increased since 2021. We have grown each quarter sales over the previous year and that growth continues.

[David Santos, EVP & Chief Commercial Officer at Rigel Pharmaceuticals]

In the 2024, we reported $33,500,000 and now for the 2025, we generated $58,900,000 Our second quarter results reflect accelerated demand through improved patient affordability in 2025 augmented by favorable gross to net dynamics, which drove a 76% increase year over year. Our commercial team has been dedicated to execution, driving continued momentum for TAVALISSE, raising awareness for GIVRETO after a successful transition into our portfolio and improving demand for ResLidia. Slide nine shows a summary of our commercial performance by product. First on TAVALISSE. I'm pleased to report another record quarter in which we generated $40,100,000 in net product sales, an increase of 52% compared to the 2024.

[David Santos, EVP & Chief Commercial Officer at Rigel Pharmaceuticals]

This growth was driven by continued strong new patient demand with another consecutive quarterly record high and increased carryover demand from new patients that started therapy in prior quarters. For GAVRETO, we delivered $11,800,000 in net product sales in Q2. As a reminder, in the 2024, we recorded $1,900,000 of revenue as GIVRETO just became commercially available from Rigel in 2024. On a sequential basis, we saw 32% revenue growth versus the 2025, as we continued to see an increase in new patients and carryover demand. We are focused on driving awareness of GIVRETO and ensuring patients are educated on the latest treatment guidelines that recommend the use of a RET inhibitor in the frontline setting.

[David Santos, EVP & Chief Commercial Officer at Rigel Pharmaceuticals]

And lastly for Reslidia, we reported $7,000,000 in net product sales, an increase of 36% compared to the prior year period reflecting demand growth. We continue to focus on educating healthcare providers about the potential benefits of Reslidia for patients with relapsed or refractory IDH1 mutant AML. Driving awareness of the efficacy data for Reslidia in the post venetoclax setting, which we believe is important to physicians, continues to be a key priority for us. We also believe we have compelling data for the earlier use of Reslidia in mutant IDH1 patients who relapse or are refractory to frontline therapy. To that end, at ASCO in June, we presented data for patients who received Reslidia after either one to two lines of therapy or three or more lines of prior therapy.

[David Santos, EVP & Chief Commercial Officer at Rigel Pharmaceuticals]

Patients in the one to two prior regimens group showed a higher overall response rate and longer median overall survival than those who had three or more prior lines of therapy, providing a rationale for initiating treatment with Brasilia earlier in the relapsed or refractory treatment paradigm. This supporting data shows why we believe we have significant opportunity to grow Reslidia in relapsed or refractory IDH1 mutant AML. Overall, we're very pleased by our commercial performance in the second quarter. And I would like to express our sincere thanks to the entire team for their outstanding performance in Q2. Moving to Slide 10, we continue to work on expanding access to our products in markets outside of The U.

[David Santos, EVP & Chief Commercial Officer at Rigel Pharmaceuticals]

S. TAVALISSE is commercially available in Japan, in Europe under the brand name Teveless and in Canada and Israel via our partners Kissei, Grifols and Medison. In addition, our partners continue to pursue regulatory approvals markets. Most recently, in early July, Kisei's licensing partner, JW Pharmaceutical Corporation, launched TAVALISSE in South Korea. For Reslidia, in 2024, we expanded our relationship with Kissei to include several countries in Asia for all potential indications.

[David Santos, EVP & Chief Commercial Officer at Rigel Pharmaceuticals]

And we entered into an exclusive license agreement with Doctor. Reddy's for all potential indications throughout Doctor. Reddy's territory. We are pleased that access to our products is expanding outside The U. S.

[David Santos, EVP & Chief Commercial Officer at Rigel Pharmaceuticals]

And we continue to explore other opportunities for partnerships to bring our products to other markets around the globe.

[David Santos, EVP & Chief Commercial Officer at Rigel Pharmaceuticals]

I will now pass the call over to Lisa to provide an update on our development pipeline. Lisa?

[Lisa Rojkjaer, EVP & Chief Medical Officer at Rigel Pharmaceuticals]

Thanks, Dave. I will now provide an overview of our pipeline progress and plans for the remainder of the year. I'm on Slide 12. Our hematology and oncology pipeline strategy is focused on the clinical development of R289, our novel dual IRAK1 and IRAK4 inhibitor in lower risk myelodysplastic syndrome, or MDS, and the expansion of elutacitinib beyond relapsed or refractory IDH1 mutated AML into other cancers with IDH1 mutations such as recurrent glioma. Beginning with R289, our Phase Ib study in patients with relapsed or refractory lower risk MDS is progressing well and enrollment in the dose escalation part of the study was completed in July.

[Lisa Rojkjaer, EVP & Chief Medical Officer at Rigel Pharmaceuticals]

We plan to share updated dose escalation data later this year. We remain on track to initiate the dose expansion part of the study in the second half of the year, which will be a randomized comparison of two doses of R289 in order to select the recommended Phase two dose for future studies. For elutacitinib, we believe it has potential in several cancers where mutated IDH1 plays a role. Regarding our partners, elutacitinib is being evaluated as maintenance therapy in IDH1 mutation positive glioma by the Connect Cancer Consortium and in IDH1 mutation positive AML and low and high risk MDS by MD Anderson. We remain open to additional opportunities or collaborations to evaluate elutacitinib in IDH1 mutated cancers.

[Lisa Rojkjaer, EVP & Chief Medical Officer at Rigel Pharmaceuticals]

Rigel also remains focused on evaluating potential acquisition and in licensing opportunities that strategically fit our hematology and oncology portfolio and infrastructure. We're focused on evaluating differentiated assets in hematology, oncology or related areas that are late stage programs. Now we'll spend a few moments on R289, our dual IRAK1 and IRAK4 inhibitor. On Slide 14, I'd like to spend a few minutes reviewing the value proposition of R289 in lower risk MDS. There are about 12,000 previously treated lower risk MDS patients in The U.

[Lisa Rojkjaer, EVP & Chief Medical Officer at Rigel Pharmaceuticals]

S. There's a high unmet need for therapies in this disease area, particularly for transfusion dependent patients. Dysregulation of inflammatory signaling is key to the pathogenesis of lower risk MDS and IRAK1 and four mediate this process. Blocking both IRAK1 and four may suppress marrow inflammation and leukemic stem and progenitor cell function and restore normal hematopoiesis. R835, the active moiety of R289, blocks Toll like receptor and IL-one receptor signaling in vitro and was active in various preclinical models of inflammation.

[Lisa Rojkjaer, EVP & Chief Medical Officer at Rigel Pharmaceuticals]

Clinical proof of concept of this anti inflammatory effect came from a healthy volunteer study in which R835 markedly suppressed LPS induced cytokine release compared to placebo. As a reminder, R289, which is currently being evaluated in the clinic, is the oral prodrug that is rapidly converted to R835 in the gut. R289 has both Fast Track and orphan drug designations from the FDA, giving the molecule an expedited regulatory pathway, potential priority review and seven years of market exclusivity upon approval. Both of these designations underscore the agency's interest in this rare disease, the unmet need of the patient population and the FDA's willingness to collaborate with Rigel in the development of R289. In addition, R289 has thus far demonstrated a promising clinical profile in a Phase Ib study.

[Lisa Rojkjaer, EVP & Chief Medical Officer at Rigel Pharmaceuticals]

The initial dose escalation data that were presented at last year's ASH Annual Meeting demonstrated promising preliminary safety and clinical activity in elderly heavily pretreated patients with relapsed or refractory lower risk MDS. While I'm here, I wanted to mention that we noted that with a recent data cut, there was a change in status for one patient previously reported with a minor response, that is a reduction in the number of red cell transfusions by more than fifty percent compared to baseline. We discovered that this patient had received additional red cell transfusions that were not entered into the database at the time of the initial analysis. Thus, this patient is no longer considered a responder. I'll discuss the study design in a moment.

[Lisa Rojkjaer, EVP & Chief Medical Officer at Rigel Pharmaceuticals]

On Slide 15, I'd like to update you on several key milestones for the program that we're focused on this year. First, as mentioned, we completed enrollment in the dose escalation part of our ongoing Phase 1b study in July. We remain on track to initiate the dose expansion phase in the second half of this year, potentially within the third quarter. We recently engaged with the FDA to discuss the dose expansion phase and to seek preliminary input on a potential path to registration. We're aligned with the FDA on the dose expansion part of the study and will provide more details on the registrational path following completion of the Phase Ib study and once we've aligned with the agency on the design of our pivotal study.

[Lisa Rojkjaer, EVP & Chief Medical Officer at Rigel Pharmaceuticals]

And lastly, we look forward to sharing updated data from the study later in the year. On the next slide, I'll review the study design. This is our multicenter open label Phase Ib study in patients with relapsedrefractory lower risk MDS that are either transfusion dependent or have symptomatic anemia. Initial data from the study was presented at ASH in late twenty twenty four. The study aims to evaluate the safety, PK and preliminary efficacy of R289 in this patient population, as well as select a dose for future studies.

[Lisa Rojkjaer, EVP & Chief Medical Officer at Rigel Pharmaceuticals]

It includes a dose escalation part utilizing a modified three plus three design evaluating six dose regimens of R289 and a dose expansion phase, which will compare two doses of R289 head to head in order to select the recommended Phase two dose. Once this occurs, we'll open up a cohort of patients to explore upfront dosing of R289 in patients that are relapsed, refractory to or ineligible for ESAs. On slide 17, I'd like to talk about the treatment landscape for lower risk MDS. MDS is a clonal disorder of hematopoietic stem cells, leading to dysplasia and ineffective hematopoiesis. The main consequences for patients are anemia and transfusion dependence, which adversely impact quality of life.

[Lisa Rojkjaer, EVP & Chief Medical Officer at Rigel Pharmaceuticals]

In addition, infections, iron overload from transfusions, and subsequent organ dysfunction all negatively impact the patient. Therapies used in the upfront setting include erythropoiesis stimulating agents or ESAs, if patients are eligible or luspatercept. Luspatercept and more recently imetelstat are also approved for ESA failure transfusion dependent lower risk MDS patients. Finally, hypomethylating agents or HMAs are also approved. However, the percentage of patients achieving transfusion independence is low.

[Lisa Rojkjaer, EVP & Chief Medical Officer at Rigel Pharmaceuticals]

With eight week transfusion independence rates approaching forty percent with luspatercept and ometelstat, there's still a need for safe effective therapies for transfusion dependent lower risk MDS patients that are relapsed refractory to or ineligible for ESAs. Now I'll shift focus to our strategic collaborations. As I've mentioned, we have collaborations in place with CONNECT and MD Anderson to evaluate elutacitinib and other cancers harboring IDH1 mutations. I'm now on Slide 19. CONNECT is a global pediatric neuro oncology consortium that we entered into a collaboration with last year.

[Lisa Rojkjaer, EVP & Chief Medical Officer at Rigel Pharmaceuticals]

In CONNECT's TARGET trial, a molecularly guided Phase trial for high grade glioma, the Rigel sponsored arm of the study called TARGET D will evaluate a post radiotherapy maintenance regimen of elutacitinib in combination with temozolomide followed by elutacitinib monotherapy in newly diagnosed patients between 12 and 39 years of age with IDH1 mutation positive high grade glioma. This study is open for enrollment. In addition to this collaboration with CONNECT, we continue to look at other opportunities to expand our studies of IDH1 mutated cancers through our own studies or collaborative partners, including a potential Rigel led Phase II glioma study. We, along with CONNECT, are excited about elutacitinib's potential to provide a much needed new treatment option to this underserved patient population with significant unmet need. On slide 20, we summarize our strategic alliance with the MD Anderson Cancer Center to advance elutacitinib more broadly into AML, MDS and beyond.

[Lisa Rojkjaer, EVP & Chief Medical Officer at Rigel Pharmaceuticals]

All four studies within this collaboration are open for enrollment, and we look forward to sharing updates in the future. Now I'll pass the call to Dean to discuss our partnered program with Eli Lilly and our financial results for the quarter. Dean?

[Dean Schorno, Executive VP & CFO at Rigel Pharmaceuticals]

Thank you, Lisa. I'm on Slide 22. Before I review our financial results for the quarter, I want to provide a brief update on our collaboration with Lilly and the related impact to our financial statements during the quarter. The RIPK1 inhibitor programs are progressing well, we're excited about the program's potential. Ocadusertib, the non CNS penetrant RIPK1 inhibitor, previously referred to as R552, is currently being studied in an adaptive Phase 2b clinical trial in up to three eighty patients with active moderate to severe rheumatoid arthritis.

[Dean Schorno, Executive VP & CFO at Rigel Pharmaceuticals]

Enrollment in the Phase 2a study is ongoing. The preclinical CNS penetrant RIPK1 inhibitor program is also progressing toward lead candidate nomination. As Raul mentioned, we notified Lilly that we will not exercise our opt in right related to the development and commercialization of ocadersertib. As a result, we recognized $40,000,000 in collaboration revenue in the second quarter. This is non cash and related to the release of the remaining cost share liability that was on our balance sheet.

[Dean Schorno, Executive VP & CFO at Rigel Pharmaceuticals]

Note that under the terms of our collaboration agreement, Ryger will continue to be entitled to receive milestone and tiered royalty payments of future net sales. Moving on to our financials. I'm on Slide number 24. We reported net product sales of $58,900,000 for the second quarter, a growth of 76% year over year, including TAVALISSE net product sales of $40,100,000 a growth of 52% year over year, GAVRETO net product sales of $11,800,000 As a reminder, GAVRETO became commercially available for Rigel in 2024, and we reported $1,900,000 of revenue for the 2024. Lastly, we reported Reslidia net product sales of $7,000,000 a growth of 36% year over year.

[Dean Schorno, Executive VP & CFO at Rigel Pharmaceuticals]

Our net product sales were recorded net of estimated discounts, chargebacks, rebates, returns, co pay assistance and other allowances of $20,700,000 We also reported $42,700,000 in contract revenues from our collaborations the second quarter, primarily consisting of the $40,000,000 of non cash revenue from Lilly as well as contributions from Riffles, Kisei and Medison related to delivery of drug supply and earned royalties, bringing our total revenues for the second quarter to $101,700,000 Moving to Slide '25 and down the income statement to cost and expenses. Our cost of product sales were approximately $4,500,000 the 2025. Total cost and expenses were $40,600,000 compared to $36,400,000 for the same period of 2024. The increase in cost and expenses was mainly due to higher cost of product sales, increased research and development costs driven by the timing of clinical activities related to elutacitinib and R289 and higher personnel related costs and stock based compensation expense. We reported net income of $59,600,000 for the second quarter compared to a net loss of $1,000,000 in the same period in 2024.

[Dean Schorno, Executive VP & CFO at Rigel Pharmaceuticals]

We ended the quarter with cash, cash equivalents and short term investments of $108,400,000 compared to $77,300,000 as of the 2024. Turning to our financial outlook for 2025, we're raising our total revenue guidance to approximately $270,000,000 to $280,000,000 an increase from our prior range of $200,000,000 to $210,000,000 This includes updated net product sales expectations of approximately $210,000,000 to $220,000,000 an increase from the prior range of $185,000,000 to $192,000,000 and contract revenues from collaborations of approximately $60,000,000 an increase from the prior range of $15,000,000 to $18,000,000 The updated total revenues and contract revenues from collaborations expectations are inclusive of the $40,000,000 in non cash contract revenue related to Rigel's agreement with Lilly. In addition, we continue to anticipate that we will report positive net income for the full year 2025, while funding existing and new clinical development programs. To wrap up my section, we look forward to continued financial discipline for the remainder of 2025 and beyond. With that, I'd like to turn the call back over to Raul. Raul?

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

Thank you, Dean. And moving on to Slide 26. To reiterate, we have made significant advancements over the last several years in expanding our hematology and oncology business. We have consistently delivered meaningful top line growth, enabling us to fund our business and strategic priorities. We have now raised our net product sales expectations for 2025 and now expect to generate 45% to 52% year over year growth, an increase from the roughly 30% growth that we delivered in the prior four years.

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

Moving on to Slide '27. For the remainder of the year, we continue to focus on increasing sales of our three commercial products and delivering on our revenue guidance. We are committed to advancing our Phase 1b clinical study evaluating R289 for the treatment of patients with lower risk MDS. We plan to share updated data by year end and potentially initiate the dose expansion phase of the study in the third quarter. For elutecitinib, we plan to continue progress to initiate a Rigel sponsored Phase II study in recurring glioma, while supporting our strategic collaborations with the CONNECT organization, as well as MD Anderson.

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

We will also continue to look for opportunities to expand our product portfolio through in license and or acquisition of synergistic late stage assets. With our anticipated strong revenue growth and continued financial discipline, Rigel is well positioned for the near term and for the long term. In closing on Slide '28, Rigel has delivered a strong 2025, and we are focused on continuing that momentum throughout the remainder of the year. Our proven strategy has built Rigel into a profitable, growing and sustainable business. And with that, I'd like to thank you for your interest, and we will now open the call to your questions. Back to you, operator.

[Operator]

Thank

[Operator]

And your first question comes from Joe Pantginis with H. C. Wainwright. Please state your question.

[Joseph Pantginis, MD & Senior Healthcare Analyst at H.C. Wainwright & Co.]

Hi, everybody. Thanks for taking the questions. So it really I mean, great growth, your nice blocking and tackling on GARVETRO and RYSLIDIA, excuse me for the pronunciation. I just I get. With regard to TAVALISSE, it looks like it saw a very nice inflection obviously with regard to the 52% growth.

[Joseph Pantginis, MD & Senior Healthcare Analyst at H.C. Wainwright & Co.]

You mentioned obviously it's due to new patient demand and increase of carryover. Just curious, can you split up the percentages contribution to this growth here?

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

Dave, can you comment on that? Thank you, Joe. Thank you for the question.

[David Santos, EVP & Chief Commercial Officer at Rigel Pharmaceuticals]

Yes. Joe, great question. And I will say that particularly in the first half of the year, we did have more new patient starts than ever before. So our percentage of our growth due to new patient starts was higher. And I think you heard me say in my prepared remarks that that was accelerated by improved patient affordability in 2025.

[Joseph Pantginis, MD & Senior Healthcare Analyst at H.C. Wainwright & Co.]

No, that's great. And just curious like what level of surprise is that and I'm sort of playing devil's advocate, surprise did you have about that growth and the affordability versus a potential bear case out there that TAVALISSE has reached a level of steady state?

[David Santos, EVP & Chief Commercial Officer at Rigel Pharmaceuticals]

Well, listen, we have been planning to continue to grow TAVALISSE. As you know, we've remained focused on new patient growth. And what did happen this year, as you know, is the coverage gap was eliminated in 2025 due to the Inflation Reduction Act. And we knew that this could potentially help us this year because as you know, Part D drugs or oral drugs, what happened in the past is patients would enter into that coverage gap, particularly at the beginning of the year, and it would be difficult for them to access product. And this year, with a $2,000 annual out of pocket cap for patients and their ability to potentially even smooth those payments out through the year.

[David Santos, EVP & Chief Commercial Officer at Rigel Pharmaceuticals]

They have much easier ability to access a drug like TAVALISSE, an oral agent. And I think, we were prepared to ensure that patients that we were ready to address this change at the beginning of the year. And so I will say that, we've always been focused on new patient starts. Is it potentially a little more benefit from improved affordability than we had anticipated? I'm not sure I would say that, but I think the team executed extremely well.

[David Santos, EVP & Chief Commercial Officer at Rigel Pharmaceuticals]

And because we have a portfolio of oral therapies, I think the entire portfolio benefited from improved portfolio affordability in 2025. And that also helped us improve our gross to net dynamics.

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

Really it's confluence of those things. It's a confluence of those things, Joe. And I think we were well aware of this coming in and well prepared to it. So it required both of those things to know what's coming, to know what you're going to do about it. And we executed, I'd say very well in the first half of the year.

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

Many of those patients carry over into subsequent quarters. And what used to be a, you know, difficult Q1s in the past, this IRA has helped that. And needless to say, more patients are getting drugs that perhaps in the past couldn't have gotten them because of the change. So that's a good thing overall.

[Joseph Pantginis, MD & Senior Healthcare Analyst at H.C. Wainwright & Co.]

No, fantastic. Appreciate all the added color and very nice to see.

Thank you. And your next question comes from Yigal Nochomovitz with Citigroup. Please state your question.

[Yigal Nochomovitz, Director at Citigroup]

Hey guys, congrats on a nice progress commercially and on the pipeline. I'm curious about the comment regarding the 32% CAGR which you noted from 2021 to 2024 and then the apparent inflection higher, substantially higher 45 to 52. Is the statement that this is the expectation sort of for the business on a go forward basis, not only this year, but into 2026 and beyond? Is it are we on a new sort of trajectory here? Or how would you frame that inflection point in terms of thinking about the longer term performance of the business?

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

Yes, I can take that, but I'll also ask Dave to comment on that. This has been a fantastic start to the year. And I think things have happened, dynamics. David just explained a few of them that occurred earlier in this year that I think gave us a boost. But the underlying business had been growing quite nicely, 32% year on year in TAVALISSE, specifically, a strong performer throughout those years, even though it's been on the market already.

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

So really a confluence of various things drove this increase in sales this year. We haven't given guidance beyond this year other than to say we continue to expect growth in the business, and we continue to have confidence that the product provide meaningful value to these patients. And now we can give make sure that more of them benefit from these products, being that they're oral in particular. And so we're very, very enthusiastic about what's to come. And I think a good, great first half of the year, the best ever, and we expect the dynamics to not change dramatically going forward. Dave?

[David Santos, EVP & Chief Commercial Officer at Rigel Pharmaceuticals]

Yeah, Raul, I would just add that we've got a growing business, obviously. We have been laser focused on ensuring patients have the opportunity to try TAVALISSE, Reslidia or Devretto, depending on what the clinician which type of patient the clinician has. And we do everything possible to make sure we're efficient in that targeting. And I think what you're seeing is our ability to grow revenues with very little incremental costs on a three product portfolio.

[David Santos, EVP & Chief Commercial Officer at Rigel Pharmaceuticals]

And that's exactly what we're executing on, looking at our impactable opportunities, targeting those and with laser like focus and going out and getting it. So yes, we definitely plan to continue to grow new patient starts and demand as we move forward.

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

You also note the leverage in the business. You have a stable, good quality commercial organization that really has delivered in the past. And now you add additional products to it and you see the economic benefit of that.

[Yigal Nochomovitz, Director at Citigroup]

Okay, thanks. And then I had a few more specific questions on glioma and the ALUTA development. What more can you say with respect to the Phase two design? How would you do that study? What would be the right comparator arm?

[Yigal Nochomovitz, Director at Citigroup]

And then regarding the work you're doing with this CONNECT and the TARGET D trial, if that looks good, how would what would you do with that data? Is that something you could then, use to first submission in pediatric or would you need to then pursue another company sponsored study to take that, pediatric segment to market?

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

I'll ask Lisa to comment on those two.

[Lisa Rojkjaer, EVP & Chief Medical Officer at Rigel Pharmaceuticals]

Yes. Thanks, Raul. And thanks for the question, Miguel. So regarding our plans, for glioma, we will be disclosing more about the design of the study in recurrent glioma probably later this year, once we're not yet in the position to do that, but stay tuned. And for the CONNECT study, that's a very good question as well.

[Lisa Rojkjaer, EVP & Chief Medical Officer at Rigel Pharmaceuticals]

We still have to discuss a little bit more with CONNECT and potentially with the agency on a potential for looking at that to support a filing. We haven't done any of that yet. I don't anticipate that we would be doing an additional study in that same space.

[Yigal Nochomovitz, Director at Citigroup]

Okay, got you. Thank you very much.

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

Thank you, Gal.

And your next question comes from Haak with Jefferies. Please state your question.

[Amin Makarem, VP - Biotech Equity Research at Jefferies]

Hi, this is Amin on for Farzin. Congrats on the quarter and thank you for taking our questions. A couple of questions from us. Well, based on what you're seeing so far in 3Q in numbers of bottles shipped and the IRA impact, how does that shape your thinking around the guidance going forward? And are there any anticipated headwinds or tailwinds specifically around TAVALISSE sales and GAVREITOR ramp up at this point? And I have a follow on.

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

Thank you, Farshan. I'll ask Dave to comment on that.

[David Santos, EVP & Chief Commercial Officer at Rigel Pharmaceuticals]

Yes. So we just grew, if you take the six months that we just completed and you look at the six months prior to that or the 2024, we just give 20% revenues in revenues. And in our guidance, at the midpoint of our guidance, we're still projecting double digit growth in our revenues. And at the top end, it's about 15%. So we are expecting growth to continue.

[David Santos, EVP & Chief Commercial Officer at Rigel Pharmaceuticals]

And when I said that about improved affordability dynamics in the first half of the year, as I said in my earlier remarks, the coverage gap was really an issue at the beginning of the year when patients hadn't been on medications and they were restarting the clock. And that was the time the doughnut hole experience was more. So we do expect that as we move into the second half of the year, there are fewer patients that kind of fall into that. So we're I don't think the impact of that will be as strong in the second half of the year. I hope that helps.

[Amin Makarem, VP - Biotech Equity Research at Jefferies]

Yes, very helpful. And how much impact are you seeing on the gross to net for the three drugs with the Part D?

[Dean Schorno, Executive VP & CFO at Rigel Pharmaceuticals]

So we haven't been specific on the gross to net. I will say that from a gross to net consideration, there's a variety of factors. There's the we made some distribution channel changes that we talked about in the back half of last year. So that's had an effect and a favorable effect. The mix also impacts gross to net, and there's some favorability, as Dave said, with respect to the IRAD adjustments.

[Dean Schorno, Executive VP & CFO at Rigel Pharmaceuticals]

And then on a go forward basis, the mix and some of the programs we do will have an impact on gross to net. So we haven't been specific on the individual products, but we expect to see some favorable gross to net as we've seen in the last couple of quarters persist.

[Amin Makarem, VP - Biotech Equity Research at Jefferies]

Thank you very much.

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

Thank you, Parsab.

And your next question comes from Kristen Kluska with Cantor Fitzgerald. Please state your question.

[Ayan Hussein, Equity Research Associate at Cantor Fitzgerald]

Hi, this is Ayn on Kristen's line. Thank you for taking our question. I understand that the primary goal in treating lower risk MDS is to reduce or eliminate transfusion dependence. What have you heard from physicians on degree of transfusion reduction or independence that is actually considered clinically meaningful in this setting?

[Lisa Rojkjaer, EVP & Chief Medical Officer at Rigel Pharmaceuticals]

Yes, I could take that. I mean, you know that as I mentioned in my prepared remarks, the, approvals of luspatercept and ometostat were based on a eight week transfusion independence rate of around thirty eight percent to forty percent for both agents. So around sixty percent of patients are still not benefiting. So I think that there's still room for improvement in this area. And with hypomethylating agents that were approved around twenty five years ago, it's really not much better.

[Lisa Rojkjaer, EVP & Chief Medical Officer at Rigel Pharmaceuticals]

So lots of room to improve. So I don't know that physicians are I think anything above this people would be looking forward to. And also considering those agents, there are also associated toxicities and a bit of an inconvenience with the route of administration. So I think, aside from the activity there, there's also room for improvement in administration.

[Ayan Hussein, Equity Research Associate at Cantor Fitzgerald]

Thank you. Understood.

[Operator]

Thank you. And there are no further questions at this time. I would like to turn the floor back over to Mr. Raul Rodriguez for closing comments. Thank you.

[Raul Rodriguez, President, CEO & Director at Rigel Pharmaceuticals]

Well, thank you. I'd like to be grateful for your attendance to this call and your interest in Rigel. I think this first half of the year, we've really have delivered well and are extremely proud on what we've been able to accomplish both in the commercial business, the financial position of the company much stronger today and stronger than I believe it's ever been, and really good advancements also in terms of our product portfolio. So for that, I'd like to thank the employees of Rigel and their dedication to what we're trying to accomplish here. This was a substantial step forward this first half of the year, we look forward to continuing that. Take care.
