- Gamida Cell conducted pre-BLA meeting for omidubicel with FDA

- FDA requested revised analysis of manufacturing data generated at Gamida Cell’s commercial manufacturing facility

- BLA submission expected in the first half of 2022

Gamida Cell Ltd. (Nasdaq: GMDA), an advanced cell therapy company committed to cures for cancer and other serious diseases, completed a Type B Pre-Biologics License Application (BLA) meeting with the U.S. Food and Drug Administration (FDA) for omidubicel, a potentially life-saving treatment for patients with blood cancers in need of stem cell transplant. The FDA requested that Gamida Cell provide revised analysis of the manufacturing data generated at Gamida Cell’s wholly-owned commercial manufacturing facility to demonstrate the comparability to the omidubicel that was produced at the clinical manufacturing sites for the Phase 3 study. The FDA did not request additional clinical data to initiate the BLA submission once analytical comparability is demonstrated. The company will continue to work collaboratively with the FDA and anticipates submitting the BLA in the first half of 2022 in lieu of the company’s previous plan to submit the BLA by the end of 2021.

“Despite the delay in timing to bring omidubicel to patients after a potential FDA approval, we are encouraged by the FDA’s reaction to our Phase 3 data as the pivotal trial of omidubicel. We have gained further clarity with the FDA on the requirements for demonstrating comparability for our commercial manufacturing facility,” said Julian Adams, Ph.D., Chief Executive Officer of Gamida Cell. “With the FDA’s feedback in hand, we believe that we are one step closer for omidubicel to be made available to patients in need.”

Omidubicel, an investigational advanced cell therapy for allogeneic bone marrow transplant

Omidubicel is the foundational product based on Gamida Cell’s proprietary NAM-enabled cell expansion technology. It is the first cell therapy for bone marrow transplant to receive Breakthrough Therapy Designation from the FDA. The BLA submission will be based on the results of an international, randomized Phase 3 study of omidubicel that was designed to evaluate the safety and efficacy of omidubicel in patients with hematologic malignancies undergoing a bone marrow transplant compared to patients who received a standard umbilical cord blood transplant. The study achieved its primary endpoint, a statistically significant reduction in time to neutrophil engraftment, as well as all key secondary endpoints. A key milestone in a patient’s recovery, neutrophil engraftment is a measure of how quickly the stem cells a patient receives in a bone marrow transplant are established and begin to make healthy new cells. In the Phase 3 study, the median time to neutrophil engraftment was 12 days for patients randomized to omidubicel compared to 22 days for the comparator group (p < 0.001). Additionally, the study met key secondary endpoints related to the speed of platelet engraftment, decrease in infections and reduction in hospitalizations, all significant clinical measures in bone marrow transplant.

About Gamida Cell

Gamida Cell is pioneering a diverse immunotherapy pipeline of potentially curative cell therapies for patients with solid tumor and blood cancers and other serious blood diseases. We apply a proprietary expansion platform leveraging the properties of NAM to allogeneic cell sources including umbilical cord blood-derived cells and NK cells to create therapies with potential to redefine standards of care. These include omidubicel, an investigational product with potential as a life-saving alternative for patients in need of bone marrow transplant, and a line of modified and unmodified NAM-enabled NK cells targeted at solid tumor and hematological malignancies.

About Omidubicel

Omidubicel is an advanced cell therapy under development as a potential life-saving allogeneic hematopoietic stem cell (bone marrow) transplant for patients with hematologic malignancies (blood cancers), for which it has been granted Breakthrough Status by the FDA. Omidubicel is also being evaluated in a Phase 1/2 clinical study in patients with severe aplastic anemia (NCT03173937). The aplastic anemia investigational new drug application is currently filed with the FDA under the brand name CordIn^®, which is the same investigational development candidate as omidubicel.
