Geron Corp., a company founded more than three decades ago, is finally celebrating its first U.S. FDA approval. The agency cleared imetelstat, branded Rytelo, for use in transfusion-dependent anemia in adults with low- to intermediate-risk myelodysplastic syndromes, specifically those requiring four or more red blood cell units over eight weeks who have failed or no longer respond to erythropoiesis-stimulating agents (ESA) or who are not eligible for ESA treatment.

After hearing two conflicting presentations of the safety and efficacy of Geron Corp.’s imetelstat, the U.S. FDA’s Oncology Drugs Advisory Committee (ODAC) voted 12-2 March 14 that the drug’s benefit outweighed its risks as a treatment for transfusion-dependent anemia in adults with low- to intermediate-1 risk myelodysplastic syndromes in patients who have failed or no longer respond to erythropoiesis stimulating agents (ESAs), or who are not eligible for ESA treatment.
