SOUTH SAN FRANCISCO, Calif., March 3, 2026 /PRNewswire/ -- Rigel Pharmaceuticals, Inc. (Nasdaq: RIGL), a commercial stage biotechnology company focused on hematologic disorders and cancer, today reported financial results for the fourth quarter and year ended December 31, 2025, including sales of TAVALISSE® (fostamatinib disodium hexahydrate), GAVRETO® (pralsetinib) and REZLIDHIA® (olutasidenib), and recent business progress.
"I am proud to highlight Rigel's tremendous progress during 2025 across each of the key value drivers of our business. We delivered record net product sales, total revenues and net income while making meaningful advances in our Phase 1b study of R289 in lower-risk MDS," said Raul Rodriguez, Rigel's president and CEO. "These 2025 accomplishments set the stage for a strong 2026, as reflected in our financial guidance and our plans to advance our R289 program in lower-risk MDS and other potential indications."
Fourth Quarter and Full Year 2025 Business Update
Commercial
Fourth quarter net product sales were $65.4 million, an increase of 41% from the same period of 2024.
2025 net product sales were $232.0 million, an increase of 60% from the same period of 2024.
Clinical Development and Regulatory
Rigel continues to advance its Phase 1b clinical study evaluating the safety, tolerability, pharmacokinetics, and preliminary efficacy of R2891, a potent and selective dual inhibitor of interleukin receptor-associated kinases 1 and 4 (IRAK1/4), in patients with relapsed or refractory (R/R) lower-risk myelodysplastic syndrome (MDS). In October 2025, Rigel announced enrollment of the first patient in the dose expansion phase of the study, where up to 40 patients will be randomized to receive either 500 mg once daily (QD) or twice daily (BID) to determine the recommended Phase 2 dose for future clinical trials.
Rigel is on track to complete enrollment of the dose expansion phase of the Phase 1b study and select the recommended Phase 2 dose for future clinical studies in the second half of 2026. The company anticipates sharing preliminary data from the dose expansion phase of the study by the end of 2026.
Updated data from the dose escalation phase of the ongoing Phase 1b clinical study of R289 were presented in an oral session at the 2025 American Society of Hematology (ASH) Annual Meeting and Exposition in December, indicating that R289 continued to be generally well tolerated in a heavily pretreated R/R lower-risk MDS patient population, the majority of whom were high transfusion burden (HTB) at baseline. Furthermore, red blood cell transfusion independence (RBC-TI ≥8 weeks) was achieved by 33% (6/18) of evaluable transfusion dependent patients receiving R289 doses of 500 mg QD and higher.
Also at the ASH Annual Meeting, four posters were presented on olutasidenib, which included data that add to the growing body of evidence supporting the benefits of its use in patients with R/R mutated isocitrate dehydrogenase-1 (mIDH1) acute myeloid leukemia (AML).
In October 2025, the first patient was enrolled in the CONNECT Phase 2 TarGeT-D study evaluating olutasidenib in combination with temozolomide, followed by olutasidenib monotherapy as a maintenance regimen for newly-diagnosed adolescent and young adult patients with a high-grade glioma harboring an IDH1 mutation (NCT06161974).
Rigel presented sub-analysis data from the ARROW study evaluating pralsetinib for the treatment of metastatic rearranged during transfection (RET) fusion-positive non-small cell lung cancer (NSCLC) at the 2025 North America Conference on Lung Cancer (NACLC) in December. The two poster presentations included efficacy and safety data for patients previously treated with immunotherapy and for patients from the United States. In the trial, median overall survival (OS) was 44.3 months for the overall patient population. Longer median OS was seen in patients treated in the United States (62.4 months).
Rigel presented the first data release for pralsetinib from the TAPISTRY study (NCT04589845) in a poster presentation at the 2026 American Society of Clinical Oncology – Gastrointestinal Cancers Symposium (ASCO-GI) in January. The analysis reported results from the Phase 2 global, open-label, multicohort study, in which the efficacy and safety of pralsetinib was evaluated in a cohort of patients with RET fusion-positive solid tumors, including pancreatic, colorectal, and hepatobiliary cancers. Pralsetinib demonstrated robust and durable activity against RET fusion-positive solid tumors, including gastrointestinal (GI) tumors, and in the efficacy evaluable population showed an overall response rate (ORR) of 67% (26/39). These data validate RET fusions as a tissue-agnostic target with sensitivity to RET inhibition, suggesting the potential therapeutic utility of pralsetinib in these patients.
On December 22, 2025, the U.S. Food and Drug Administration (FDA) notified Rigel of the approval of a Prior Approval supplemental New Drug Application for GAVRETO, which updated the U.S. Prescribing Information to add a boxed warning regarding serious infections, including opportunistic infections. Rigel previously communicated this risk information to healthcare providers via a Dear Healthcare Provider letter in October 2024. The FDA also notified Rigel that it has met its postmarketing commitment for GAVRETO from its September 2020 accelerated approval to submit the final report for the AcceleRET-Lung study. In October 2023, the FDA granted full approval to GAVRETO for adult patients with metastatic RET fusion-positive NSCLC.
Publication
A paper titled "Olutasidenib for Mutated IDH1 Acute Myeloid Leukemia: Final Five-Year Results from the Phase 2 Pivotal Cohort" was published in November 2025 by Jorge E. Cortes, M.D., Phase 2 trial investigator and Director, Georgia Cancer Center, Cecil F. Whitaker Jr., GRA Eminent Scholar Chair in Cancer, in the Journal of Hematology & Oncology. The publication reports the final 5-year data from the pivotal cohort of the registrational trial evaluating olutasidenib for the treatment of patients with R/R mIDH1 AML, which includes an additional two years of efficacy and safety data. These 5-year data further support the durable responses and manageable safety profile observed with olutasidenib in patients with R/R mIDH1 AML, including those previously treated with venetoclax-based regimens.
Corporate
Michael P. Miller joined Rigel's Board of Directors as an independent director and member of the Board of Directors' Compensation Committee, effective February 1, 2026.

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 229,000 adults in the U.S. will be diagnosed with lung cancer in 2026. 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 77% 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 22,720 new cases in the United States, most in adults, in 2026.4
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.
