Gamida Cell Announces FDA Acceptance of Biologics License Application for Omidubicel with Priority Review

- If approved, omidubicel will be the first allogeneic advanced stem cell therapy donor source for patients with blood cancers in need of a stem cell transplant -

- PDUFA target action date is January 30, 2023 -

BOSTON, MA, USA I August 01, 2022 IGamida Cell Ltd. (Nasdaq: GMDA), the leader in the development of NAM-enabled cell therapy candidates for patients with hematologic and solid cancers and other serious diseases, announced today that the U.S. Food and Drug Administration (FDA) has accepted for filing the Company’s Biologics License Application (BLA) for omidubicel for the treatment of patients with blood cancers in need of an allogenic hematopoietic stem cell transplant. Omidubicel is a first-in-class, advanced NAM-enabled stem cell therapy candidate with breakthrough and orphan drug designations.

The FDA granted Priority Review for the BLA and has set a Prescription Drug User Fee Act (PDUFA) target action date of January 30, 2023. The FDA grants Priority Review to product applications that, if approved, would provide significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions when compared to standard applications. At this time, the FDA has indicated that it is not planning an advisory committee meeting as part of the BLA review.

“The FDA’s acceptance of our BLA with Priority Review signifies a critical milestone in our mission to deliver a new stem cell therapy option for patients in need of a donor for an allogeneic stem cell transplant,” said Julian Adams, Ph.D., chief executive officer of Gamida Cell. “We are encouraged by the positive and sustained follow-up results from patients participating in the Phase 3 trial of omidubicel, including a positive overall survival trend one-year out from treatment. These results provide promising rationale that, if approved, omidubicel could become a treatment of choice for patients in need of an allo-HSCT transplant. We look forward to working with the FDA throughout the review process to bring omidubicel to patients as quickly as possible.”

Upon FDA approval, omidubicel will be manufactured at the Gamida Cell owned manufacturing facility in Israel. This is a newly constructed, state-of-the-art, modular facility which allows for additional capacity to be added to address growing demand. Batches from this facility were used to support the BLA for omidubicel and the facility is currently manufacturing clinical batches.

The omidubicel BLA is supported by the statistically significant results from Gamida Cell’s pivotal Phase 3 study, the results of which were published in Blood, the official journal of the American Society of Hematology. Results for the study’s primary endpoint, the median time to neutrophil engraftment in patients with hematologic malignancies undergoing allogeneic bone marrow transplant with omidubicel compared to standard umbilical cord blood (UCB), demonstrated a median time to neutrophil engraftment of 12 days for patients randomized to omidubicel compared to 22 days for the comparator group (p < 0.001). The secondary endpoints of this Phase 3 study were all achieved and were statistically significant. These secondary endpoints were platelet engraftment, the rate of infection, and days alive and out of hospital. Omidubicel was generally well tolerated in the Phase 3 study.

The full Blood manuscript is available here: https://ashpublications.org/blood/article/doi/10.1182/blood.2021011719/476235/Omidubicel-Versus-Standard-Myeloablative-Umbilical.

In 2019, approximately 8,000 patients who were 12 years old and up with hematologic malignancies underwent an allogeneic stem cell transplant in the United States.1 Unfortunately, it is estimated that another 1,200 patients were eligible for transplant but could not find a donor source.2 If approved, omidubicel has the potential to improve outcomes for patients based on transplanter feedback and to potentially increase access for patients to get to transplant. If approved, omidubicel has the potential to treat approximately 2,000 – 2,500 patients each year in the U.S.

Conference Call Information

A replay of the webcast will be available approximately two hours after the event, for approximately 30 days.

About Omidubicel

Omidubicel is an advanced cell therapy candidate developed as a potential life-saving allogeneic hematopoietic stem cell (bone marrow) transplant for patients with blood cancers. Omidubicel demonstrated a statistically significant reduction in time to neutrophil engraftment in comparison to standard umbilical cord blood in an international, multi-center, randomized Phase 3 study (NCT0273029) in patients with hematologic malignancies undergoing allogeneic bone marrow transplant. The Phase 3 study also showed reduced time to platelet engraftment, reduced infections and fewer days of hospitalization. One-year post-transplant data showed sustained clinical benefits with omidubicel as demonstrated by significant reduction in infectious complications as well as reduced non-relapse mortality and no significant increase in relapse rates nor increases in graft-versus-host-disease (GvHD) rates. Omidubicel is the first stem cell transplant donor source to receive Breakthrough Therapy Designation from the FDA and has also received Orphan Drug Designation in the US and EU.

Omidubicel is an investigational stem cell therapy candidate, and its safety and efficacy have not been established by the FDA or any other health authority. For more information about omidubicel, please visit https://www.gamida-cell.com.

About NAM Technology

Our NAM-enabling technology is designed to enhance the number and functionality of targeted cells, enabling us to pursue a curative approach that moves beyond what is possible with existing therapies. Leveraging the unique properties of NAM (nicotinamide), we can expand and metabolically modulate multiple cell types — including stem cells and natural killer cells — with appropriate growth factors to maintain the cells’ active phenotype and enhance potency. Additionally, our NAM technology improves the metabolic fitness of cells, allowing for continued activity throughout the expansion process.

About Gamida Cell

Gamida Cell is pioneering a diverse immunotherapy pipeline of potentially curative cell therapy candidates 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 therapy candidates 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.
