FDA approves RYTELO by Geron for myelodysplastic syndromes

Geron Corporation (Nasdaq: GERN), a pioneering biopharmaceutical company focused on changing the course of blood cancer treatment, has announced a landmark achievement with the U.S. Food and Drug Administration (FDA) approval of RYTELO (imetelstat) for adult patients with low- to intermediate-1 risk myelodysplastic syndromes (MDS) with transfusion-dependent anemia. This approval addresses a critical need for patients who have not responded to, lost response to, or are ineligible for erythropoiesis-stimulating agents (ESAs).

RYTELO: Innovating Treatment for Myelodysplastic Syndromes

RYTELO is the world’s first telomerase inhibitor approved for this indication, offering hope to approximately 14.4 million individuals projected to suffer from atrial fibrillation by 2060 in the European Union. The drug promises significant clinical benefits, notably the potential for patients to experience freedom from red blood cell transfusions and symptomatic anemia for more than 24 weeks.

John A. Scarlett, M.D., Chairman and Chief Executive Officer of Geron, expressed his enthusiasm for this breakthrough, stating, “The approval of RYTELO as the first telomerase inhibitor is a testament to the power of our science and the passion of our people to innovate in the field of blood cancer.”

The Clinical Impact of RYTELO

Derived from the results of the IMerge Phase 3 clinical trial, published in The Lancet, RYTELO has demonstrated significantly higher rates of red blood cell transfusion independence compared to placebo. The trial met its primary and key secondary endpoints, confirming RYTELO’s efficacy in achieving sustained and durable transfusion independence.

Rami Komrokji, MD, Vice Chair of the Malignant Hematology Department at Moffitt Cancer Center and an investigator of the trial, highlighted the treatment’s potential. “The approval of RYTELO potentially changes practice for us, providing a treatment that delivers sustained and durable transfusion independence and increases in hemoglobin levels, within a well-characterized safety profile,” he noted.

Safety and Administration

The safety profile of RYTELO is well-characterized, with the most common serious adverse reactions being manageable cases of neutropenia and thrombocytopenia. These side effects are familiar to hematologists and generally resolve with dose modifications. RYTELO is administered as an intravenous infusion every four weeks, aligning with routine blood count monitoring.

Future Directions and Patient Support

With the approval of RYTELO, Geron aims to transform the treatment landscape for patients with myelodysplastic syndromes. The company has also initiated the REACH4RYTELO Patient Support Program to ensure broad access to this innovative treatment, providing a range of resources to support access and affordability.

The FDA’s approval of RYTELO by Geron Corporation marks a significant advancement in the treatment of blood cancers, particularly low-risk myelodysplastic syndromes. This first-in-class telomerase inhibitor not only addresses a high unmet need but also sets a new standard for the care of patients with this challenging condition.
