Rigel Pharmaceuticals, Inc. announced one oral and four poster presentations at the European Hematology Association (EHA) 2024 Hybrid Congress in Madrid, Spain being held June 13-16, 2024, and online. The oral presentation includes five-year results from the pivotal cohort of the registrational Phase 2 trial of REZLIDHIA® (olutasidenib) for the treatment of relapsed or refractory (R/R) mutated isocitrate dehydrogenase-1 (mIDH1) acute myeloid leukemia (AML). The oral presentation will be given by Dr. Jorge E. Cortes, Director, Georgia Cancer Center, Cecil F. Whitaker Jr., GRA Eminent Scholar Chair in Cancer, and Phase 2 trial investigator, who will present an overview of the five-year study results, including transfusion independence, overall survival and patients R/R to prior venetoclax.

In May, Dr. Cortes was published in the Expert Review of Hematology outlining the drug profile and summarizing key safety and efficacy data for olutasidenib, including in patients previously treated with venetoclax or ivosidenib. The company's poster presentations include data on the safety and efficacy of olutasidenib treatment in multiple subgroups, including elderly patients, patients who had previously failed venetoclax treatment and as a bridge to allogeneic hematopoietic stem cell transplantation (HSCT) in patients with R/R mIDH1 AML. In addition, data from olutasidenib treatment in patients with mIDH1 AML secondary to myeloproliferative neoplasms (MPN) will be presented.
