SOUTH SAN FRANCISCO, Calif., Jan. 13, 2025 /PRNewswire/ -- Rigel Pharmaceuticals, Inc. (Nasdaq: RIGL), a commercial stage biotechnology company focused on hematologic disorders and cancer, today provided a business update including preliminary total revenue and net product sales for the fourth quarter of 2024, ongoing activity from the commercial business and development pipeline, and its financial outlook for 2025.

"2024 was a transformational year for Rigel as we successfully executed on our corporate strategy to grow our hematology and oncology focused organization. We generated record sales of both TAVALISSE and REZLIDHIA and welcomed a third product to our commercial portfolio, GAVRETO, which made a substantial contribution to our sales in the latter half of the year. This commercial success, combined with our commitment to financial discipline, enabled Rigel to reach financial breakeven, a key milestone for the company," said Raul Rodriguez, Rigel's president and CEO. "In addition, we advanced our development pipeline, with the Phase 1b study of R289 in lower-risk MDS continuing to enroll patients and publishing promising initial safety and efficacy data. Building on this progress, we will continue to implement effective strategies that further grow and advance our portfolio in 2025, thereby generating significant value for Rigel and our shareholders."

Commercial Update

• TAVALISSE surpassed $100 million in net product sales in 2024, reporting $104.8 million in net product sales.
• Rigel entered into an exclusive license agreement with Dr. Reddy's in November to develop and commercialize REZLIDHIA in all potential indications throughout Dr. Reddy's territory, which includes Latin America, South Africa, certain countries in the Commonwealth of Independent States (CIS), India, certain countries in Southeast Asia and North Africa, Australia and New Zealand. Rigel is entitled to receive an upfront cash payment of $4.0 million with the potential for up to $36.0 million in future regulatory and commercial milestone payments.
• In December, Rigel's partner Knight Therapeutics announced Mexico's Comisión Federal para la Protección contra Riesgos Sanitarios approved TAVALISSE for the treatment of thrombocytopenia in adult patients with chronic immune thrombocytopenia (ITP) who have had an insufficient response to a previous treatment.

Clinical and Development Update

• R289¹, a novel and selective dual IRAK1/4 inhibitor, has been granted Fast Track designation for the treatment of previously-treated transfusion dependent lower-risk MDS and Orphan Drug designation for the treatment of MDS by the U.S. Food and Drug Administration (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 myelodysplastic syndrome (MDS). Enrollment in the fifth dose level (500mg / 250mg split dose) is ongoing.
• Rigel presented initial data from the ongoing Phase 1b clinical study of R289 at the 66th American Society of Hematology (ASH) Annual Meeting and Exposition in December, demonstrating that R289 was generally well tolerated in this heavily pretreated R/R lower-risk MDS patient population, the majority of whom were high transfusion burden (HTB) at baseline.
• In an ad-hoc analysis of the R289 Phase 1b initial data, responding patients (those achieving transfusion independence) appeared to have a greater increase in hemoglobin level over time compared to non-responding patients.
• Also at the ASH Annual Meeting, four posters were presented on olutasidenib, which included data that adds to the growing body of evidence supporting the benefits of its use in patients with mIDH1 AML.
• As part of a multi-year strategic development alliance, Rigel and The University of Texas MD Anderson Cancer Center (MD Anderson), opened enrollment for two trials in December. The trials are a Phase 2 study in patients with IDH1-mutated clonal cytopenia of undetermined significance (CCUS), lower-risk MDS and chronic myelomonocytic leukemia (CMML), and a Phase 1/2 study of olutasidenib maintenance therapy following an allogeneic stem cell transplant for patients with IDH1-mutated myeloid malignancies. The Phase 1b/2 triplet therapy trial of decitabine and venetoclax in combination with olutasidenib in patients with mIDH1 AML is ongoing.
• In December, in a paper titled "Olutasidenib demonstrates significant clinical activity in mutated IDH1 acute myeloid leukaemia arising from a prior myeloproliferative neoplasm", was published by Stéphane de Botton, M.D., Ph.D., head of translational research in hematology, Institut Gustave Roussy, France, in the British Journal of Haematology.
• In November, the National Comprehensive Cancer Network^® (NCCN^®) added olutasidenib to the latest NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines^®) for Myelodysplastic Syndromes. Olutasidenib was added as a recommended option to the following treatment algorithms: Management of Lower-Risk Disease, Management of Lower-Risk Disease - Evaluation of Related Anemia and Management of Higher-Risk Disease, and was recommended as NCCN Category 2B in all circumstances. If mIDH1 positive, olutasidenib was either recommended as a single agent, in combination with azacitidine, or both.*

2025 Outlook

Rigel anticipates 2025 total revenue of approximately $200 to $210 million, including:

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

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

In addition, Rigel plans to initiate a Phase 2 clinical study in recurrent glioma in 2025.

About ITP
In patients with ITP (immune thrombocytopenia), 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. People 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 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 20,800 new cases in the United States, most in adults, in 2024.²

Relapsed AML affects about half of all patients who, following treatment and remission, experience a return of leukemia cells in the bone marrow.³ 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.⁴ 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 NSCLC
It is estimated that over 230,000 adults in the U.S. will be diagnosed with lung cancer in 2024.  Lung cancer is the leading cause of cancer death in the U.S, with NSCLC being the most common type accounting for 80-85% of all lung cancer diagnoses.⁵ RET fusions are implicated in approximately 1-2% of patients with NSCLC.⁶

About TAVALISSE^®
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.

*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).
