Geron Corporation

Geron is a late-stage clinical biopharmaceutical company focused on the development and potential commercialization of a first-in-class telomerase inhibitor, imetelstat, an innovative therapeutic for hematologic myeloid malignancies. Geron is committed to improving and extending the lives of patients by changing the course of these diseases by targeting telomerase. We are currently focused on the development and potential commercialization of imetelstat, a first in class telomerase inhibitor, and are conducting two ongoing Phase 3 clinical trials that are intended to enable registration: (i) IMerge Phase 3 in Low or Intermediate-1 risk myelodysplastic syndromes, or lower risk MDS, and (ii) IMpactMF in Intermediate-2 or High-risk myelofibrosis, or refractory MF.

Assuming enrollment in IMerge Phase 3 is completed in the fourth quarter of 2021, and top-line results from IMerge Phase 3 that support the submissions are available in the first quarter of 2023, we plan to submit in 2023 a New Drug Application, or NDA, in the United States, and a Marketing Authorization Application, or MAA, in Europe, for imetelstat in lower risk MDS. Under either a priority review or a standard review for the NDA, upon potential approval by the FDA, we expect that commercial launch of imetelstat in lower risk MDS in the United States could occur in the first half of 2024. In Europe, we anticipate review of the MAA by the European Medicines Agency, or EMA, could take approximately 12 months and commercial launch of imetelstat in lower risk MDS in Europe could occur in the second half of 2024.
