2025, the company expects to report fourth quarter total revenue of $69.8
million, compared to $57.6 million for the same period of 2024.
-- Rigel expects to report fourth quarter of 2025 gross product sales of
$84.5 million. Net product sales are expected to be $65.4 million,
compared to $46.5 million for the same period of 2024, including:

million, including net product sales of $232.0 million and contract
revenues of $62.3 million, compared to total revenue of $179.3 million in
2024, which included net product sales of $144.9 million and contract
revenues of $34.4 million. Expected 2025 contract revenues and total
revenue include $40.0 million in non-cash revenue recognized in the

share liability related to the agreement with Lilly for the development
and commercialization of ocadusertib.
-- Rigel expects to report cash, cash equivalents, and short-term
investments of approximately $154.6 million as of December 31, 2025,
compared to $77.3 million as of December 31, 2024.
The above information is preliminary, has not been audited, and is subject to change upon the audit of Rigel's financial statements for the fourth quarter and year ended December 31, 2025. Rigel expects to provide complete fourth quarter and full year 2025 financial results in March 2026.
Commercial
-- Rigel's commercial portfolio is expected to report preliminary full-year
net product sales of $232.0 million, growth of 60% compared to 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.
-- Rigel announced updated data from the dose escalation phase of the
ongoing Phase 1b clinical study of R289 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 at least 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, 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.
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.
2026 Outlook
Rigel anticipates 2026 total revenue of approximately $275 to $290 million, including:
-- Net product sales of approximately $255 to $265 million. -- Contract revenues of approximately $20 to $25 million.
The company anticipates it will report positive net income for the full year 2026, while funding existing and new clinical development programs.
Upcoming Investor Event
Raul Rodriguez, Rigel's president and CEO, will present a company overview at the 44th Annual J.P. Morgan Healthcare Conference in San Francisco, CA on Wednesday, January 14, 2026 at 3:00 p.m. PT (6:00 p.m. ET).

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.
About TAVALISSE(R)
TAVALISSE (fostamatinib disodium hexahydrate) tablets is indicated for the treatment of thrombocytopenia in adult patients with chronic immune thrombocytopenia (ITP) who have had an insufficient response to a previous treatment.
Please click here for Important Safety Information and Full Prescribing Information for TAVALISSE.
About GAVRETO(R)
GAVRETO is indicated for the treatment of adult patients with metastatic rearranged during transfection (RET) fusion-positive non-small cell lung cancer (NSCLC) as detected by an FDA-approved test and adult and pediatric patients 12 years of age and older with advanced or metastatic RET fusion-positive thyroid cancer who require systemic therapy and who are radioactive iodine-refractory (if radioactive iodine is appropriate).*
*Thyroid indication is approved under accelerated approval based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trial(s).
