R&D Momentum: Targeting High-Value Niche Markets

Rigel's R&D pipeline is equally compelling, with multiple late-stage trials advancing its leadership in genetically defined cancers and immune-mediated conditions. The company's olutasidenib program, for instance, is expanding beyond relapsed/refractory AML into newly diagnosed IDH1-mutated AML. A Phase 2 trial (NCT06782542) evaluating olutasidenib in combination with venetoclax and azacitidine began in June 2025Rigel Pharmaceuticals, Inc. - Drug pipelines, Patents, Clinical trials^[1], building on earlier data showing a 53% composite complete remission rate in post-myeloproliferative neoplasm (MPN) AML patientsRigel Pharmaceuticals, Inc. - Drug pipelines, Patents, Clinical trials^[1].

Another key catalyst is R289, a dual IRAK1/4 inhibitor for lower-risk myelodysplastic syndrome (MDS). With Orphan Drug and Fast Track designations from the FDARigel Pharmaceuticals, Inc. - Drug pipelines, Patents, Clinical trials^[1], R289 is in Phase 1b trials and has shown promising safety and efficacy signals.
