SOUTH SAN FRANCISCO, Calif., May 6, 2025 /PRNewswire/ -- Rigel Pharmaceuticals, Inc. (Nasdaq: RIGL), a commercial stage biotechnology company focused on hematologic disorders and cancer, today reported financial results for the first quarter ended March 31, 2025, including sales of TAVALISSE^® (fostamatinib disodium hexahydrate), GAVRETO^® (pralsetinib) and REZLIDHIA^® (olutasidenib), and recent business progress.

"Our first quarter results reflect the continued strength of our growing commercial business. This robust year-over-year revenue growth coupled with our continued financial discipline enabled us to generate more than $11 million in net income this quarter. These results uniquely position us to invest in our pipeline, including our ongoing Phase 1b clinical study evaluating R289 in patients with relapsed or refractory lower-risk MDS," said Raul Rodriguez, Rigel's president and CEO. "With a strong start to the year, we are focused on continuing our commercial growth, and building and advancing our development pipeline, including sharing data from the dose escalation portion of our R289 study later this year."

First Quarter 2025 Business Update

Commercial

• Net product sales of $43.6 million, an increase of 68% from the same period of 2024. Year-over-year commercial strength was driven by the expansion of the commercial portfolio, including the successful integration of GAVRETO.
• Rigel's partner Kissei Pharmaceutical Co., Ltd. (Kissei) announced in January that the Korean Ministry of Food and Drug Safety approved TAVALISSE for the treatment of thrombocytopenia in adult patients with chronic idiopathic thrombocytopenic purpura who have had an insufficient response to a previous treatment. In the first quarter, Rigel recognized $3.0 million in regulatory milestone revenue in connection with this approval.

Clinical Development

• R289¹, a novel and selective dual interleukin receptor-associated kinases 1 and 4 (IRAK1/4) inhibitor, was granted Orphan Drug designation for the treatment of myelodysplastic syndromes by the U.S. Food and Drug Administration (FDA) in January. R289 was previously granted Fast Track designation for the treatment of previously-treated transfusion dependent lower-risk myelodysplastic syndrome (MDS) by the FDA.
• Rigel continues to advance its Phase 1b clinical study evaluating the safety, tolerability, pharmacokinetics, and preliminary efficacy of R289 in patients with relapsed or refractory (R/R) lower-risk MDS. Enrollment in the sixth dose level (500 mg twice daily) is ongoing.

Corporate

• Dr. Mark Frohlich joined Rigel's Board of Directors as an independent director and member of the Board of Director's Corporate Governance, Health Care Compliance Oversight and Nominating Committee, and the Scientific and Clinical Trial Advisory Committee, effective March 6, 2025.
• In March, Rigel announced it entered into a settlement agreement with Annora Pharma Private Ltd., Hetero Labs Ltd., and Hetero USA, Inc. (collectively "Annora") resolving patent litigation related to TAVALISSE. The litigation resulted from submission by Annora of an Abbreviated New Drug Application to the FDA seeking approval to market a generic version of TAVALISSE in the United States. Under the terms of the settlement agreement, Annora will have a license to sell its generic product in Q2 2032 or earlier under certain circumstances. In accordance with the agreement, the parties terminated all ongoing litigation between Rigel and Annora regarding TAVALISSE patents pending in New Jersey.
• In late April, Rigel notified Eli Lilly and Company (Lilly) that it will not exercise its opt-in right related to the development and commercialization of ocadusertib (previously R552) for the treatment of non-central nervous system (CNS) diseases. As a result of this notification, in the second quarter of 2025, Rigel expects to recognize approximately $40.0 million in non-cash revenue resulting from the release of the remaining cost share liability currently on the balance sheet. Per the agreement with Lilly, Rigel will continue to be entitled to receive milestone and tiered royalty payments on future net sales of ocadusertib and its CNS penetrant program.

First Quarter 2025 Financial Update
For the first quarter ended March 31, 2025, total revenues were $53.3 million, consisting of $43.6 million in net product sales and $9.8 million in contract revenues from collaborations. Net product sales grew 68% compared to $26.0 million in the same period of 2024. TAVALISSE net product sales were $28.5 million, growth of 35% compared to $21.1 million in the same period of 2024. GAVRETO net product sales were $9.0 million. GAVRETO became commercially available from Rigel in June 2024. REZLIDHIA net product sales were $6.1 million, growth of 25% compared to $4.9 million in the same period of 2024. Contract revenues from collaborations primarily consisted of $4.7 million of revenue from Grifols S.A. related to delivery of drug supplies and earned royalties, $4.6 million of revenue from Kissei related to the milestone payment and delivery of drug supplies and $0.4 million of revenue from Medison Pharma related to delivery of drug supplies and earned royalties.

Total costs and expenses were $40.6 million compared to $36.5 million for the same period of 2024. The increase in costs and expenses was mainly due to increased personnel-related costs, and higher research and development costs driven by timing of clinical activities related to R289 and olutasidenib. In addition, cost of product sales increased, driven by increased product sales, higher royalties and amortization of intangible assets. These increases were partially offset by decreased stock-based compensation expenses.

Rigel reported net income of $11.4 million, or $0.64 basic and $0.63 diluted per share, compared to a net loss of $8.2 million, or $0.47 basic and diluted per share, for the same period of 2024. The basic and diluted share and per share amounts for the prior period have been restated to reflect the 1-for-10 reverse stock split effected on June 27, 2024 on a retroactive basis.

Cash, cash equivalents and short-term investments as of March 31, 2025 was $77.1 million, compared to $77.3 million as of December 31, 2024.

2025 Outlook
Rigel continues to anticipate 2025 total revenue of approximately $200 to $210 million, which includes:

• Net product sales of approximately $185 to $192 million.
• Contract revenues from collaborations of approximately $15 to $18 million.

The revenue ranges above exclude approximately $40.0 million in non-cash revenue that Rigel expects to recognize in the second quarter of 2025 related to the release of the remaining cost share liability from Rigel's collaboration with Lilly for the development and commercialization of ocadusertib.

The company anticipates it will report positive net income for the full year 2025, while funding existing and new clinical development programs.

About ITP
In patients with immune thrombocytopenia (ITP), the immune system attacks and destroys the body's own blood platelets, which play an active role in blood clotting and healing. Common symptoms of ITP are excessive bruising and bleeding. Patients suffering with chronic ITP may live with an increased risk of severe bleeding events that can result in serious medical complications or even death. Current therapies for ITP include steroids, blood platelet production boosters (TPO-RAs), and splenectomy. However, not all patients respond to existing therapies. As a result, there remains a significant medical need for additional treatment options for patients with ITP.

About NSCLC
It is estimated that over 226,000 adults in the U.S. will be diagnosed with lung cancer in 2025. Lung cancer is the leading cause of cancer death in the U.S, with non-small cell lung cancer (NSCLC) being the most common type accounting for 85-90% of all lung cancer diagnoses.² RET fusions are implicated in approximately 1-2% of patients with NSCLC.³

About AML
Acute myeloid leukemia (AML) is a rapidly progressing cancer of the blood and bone marrow that affects myeloid cells, which normally develop into various types of mature blood cells. AML occurs primarily in adults and accounts for about 1 percent of all adult cancers. The American Cancer Society estimates that there will be about 22,010 new cases in the United States, most in adults, in 2025.⁴

Relapsed AML affects about half of all patients who, following treatment and remission, experience a return of leukemia cells in the bone marrow.^5,6 Refractory AML, which affects between 10 and 40 percent of newly diagnosed patients, occurs when a patient fails to achieve remission even after intensive treatment.⁷ Quality of life declines for patients with each successive line of treatment for AML, and well-tolerated treatments in relapsed or refractory disease remain an unmet need.
