Geron Announces PDUFA Date for Imetelstat NDA in Lower Risk MDS

Geron Corporation (Nasdaq: GERN), a late-stage clinical biopharmaceutical company, today announced that the United States Food and Drug Administration (FDA) has assigned a standard review and a Prescription Drug User Fee Act (PDUFA) action date of June 16, 2024 for Geron’s New Drug Application (NDA) for imetelstat for the treatment of transfusion-dependent anemia in patients with lower risk myelodysplastic syndromes (MDS). In addition, the FDA informed the Company that it is currently planning to hold an advisory committee meeting as part of the NDA review.

“We look forward to working with the FDA to complete the NDA review process on a timely basis,” said John A. Scarlett, M.D., Geron’s Chairman and Chief Executive Officer. “With the PDUFA date now set, we continue to expect an imetelstat launch in the United States by the end of the first half of 2024, subject to FDA approval.”

About Imetelstat

Imetelstat is a novel, first-in-class telomerase inhibitor exclusively owned by Geron and being developed in hematologic malignancies. Data from non-clinical studies and clinical trials of imetelstat provide strong evidence that imetelstat targets telomerase to inhibit the uncontrolled proliferation of malignant stem and progenitor cells in myeloid hematologic malignancies resulting in malignant cell apoptosis and potential disease-modifying activity. Imetelstat has been granted Fast Track designation by the U.S. Food and Drug Administration for both the treatment of adult patients with transfusion dependent anemia due to Low or Intermediate-1 risk MDS that is not associated with del(5q) who are refractory or resistant to an erythropoiesis stimulating agent, and for adult patients with Intermediate-2 or High-risk MF whose disease has relapsed after or is refractory to janus associated kinase (JAK) inhibitor treatment. Imetelstat is currently not approved by any regulatory authority.
