Geron Corporation announced the completion of patient enrollment in the IMerge Phase 3 clinical trial to evaluate imetelstat, a first-in-class telomerase inhibitor, in lower risk myelodysplastic syndromes (MDS). Based upon current planning assumptions, Geron expects top-line results for IMerge Phase 3 to be available at the beginning of January 2023. Patients from the IMerge Phase 2 clinical trial achieved durable transfusion independence with imetelstat treatment, including transfusion-free periods greater than one year, irrespective of the disease subgroup, such as ringed sideroblast positive or ringed sideroblast negative. Such durability provides significant and meaningful clinical benefit to lower risk MDS patients given their chronic anemia and the debilitating impact of serial blood transfusions. In addition, depletion of cytogenetic abnormalities and reductions in key driver mutations associated with lower risk MDS were observed, and these results were also correlated with transfusion independence. Based on the IMerge Phase 2 data, taken together, the durability, molecular and cytogenetic data provide strong evidence for disease-modifying activity of imetelstat, which has the potential to differentiate it from other currently approved and investigational treatments in lower risk MDS.
