High-risk Hematologic Malignancies
About Omidubicel
Omidubicel is a NAM-enabled stem cell therapy candidate under development as a potential life-saving allogeneic hematopoietic stem cell (bone marrow) transplant solution for patients with hematologic malignancies (blood cancers). Omidubicel is the first bone marrow transplant product to receive Breakthrough Therapy Designation from the U.S. Food and Drug Administration and has also received Orphan Drug Designation in the U.S. and EU.
Development status
Omidubicel has been studied in an international, multi-center, randomized Phase 3 clinical study evaluating its safety and efficacy compared to standard umbilical cord blood transplant.
- The study achieved its primary endpoint (p<0.001). In the intent-to-treat analysis, median time to neutrophil engraftment was 12 days for patients receiving omidubicel (95% CI: 10-15 days) compared to 22 days for the comparator group (95% CI: 19-25 days).
- Omidubicel was generally well tolerated. Among patients who were transplanted per protocol, rates of acute and chronic graft-versus host disease were similar and cumulative incidence of infections was significantly smaller in omidubicel compared to controls for both viral infections and bacterial or invasive fungal infections.
- The study also met all three of its secondary endpoints, improving platelet engraftment, and reductions in infections and hospitalizations, which are key measures for success for bone marrow transplant.
The Phase 3 data also show that during the first 100 days of treatment, omidubicel-treated patients had significantly shorter durations of hospitalization, intensive care unit time, consultant visits, procedures, and transfusions than the control arm. These data provide further evidence of the clinical benefit associated with the more rapid hematopoietic recovery in patients treated with omidubicel and the corresponding reduction in healthcare resource utilization.
Full safety and efficacy data from this Phase 3 study have been published in Blood.
On August 1, the U.S. Food and Drug Administration accepted for filing the Company’s Biologics License Application for omidubicel for the treatment of patients with blood cancers in need of an allogenic hematopoietic stem cell transplant. The FDA granted Priority Review for the BLA and has set a target action date of May 1, 2023.

About Omidubicel
Omidubicel is an advanced cell therapy under development as a potential life-saving allogeneic hematopoietic stem cell (bone marrow) transplant solution for patients with hematologic malignancies (blood cancers). Omidubicel is the first bone marrow transplant product to receive Breakthrough Therapy Designation from the U.S. Food and Drug Administration and has also received Orphan Drug Designation in the U.S. and EU.
Clinical Trial Information
Omidubicel is being evaluated in an ongoing investigator-sponsored Phase 1/2 study in patients with severe aplastic anemia.
In a poster presentation at the American Society of Hematology (ASH) 62nd Annual Meeting in December 2020, it was shown that patients with severe aplastic anemia treated with omidubicel achieved sustained early engraftment. These data are the first evidence that omidubicel can result in rapid engraftment and can achieve sustained hematopoiesis in patients who are at high risk for graft failure with conventional umbilical cord blood transplant.

Non-Hodgkin Lymphoma, Multiple Myeloma
About GDA-201
GDA-201 is an innate natural killer (NK) cell immunotherapy candidate for the treatment of hematologic and solid tumors in combination with standard of care antibody therapies. When combined with targeted antibodies, GDA-201 has shown enhanced antibody-dependent cellular toxicity, or ADCC. In April 2022, the U.S. Food and Drug Administration (FDA) cleared our investigational new drug (IND) application and removed the clinical hold for a cryopreserved formulation of GDA-201.
Clinical Trial Information
The study is a multi-center, open label trial evaluating the cryopreserved formulation of GDA-201. It is currently open to enrollment. The Phase 1 portion of the study is designed to evaluate the safety of GDA-201 in patients with follicular lymphoma (FL), diffuse large B-cell lymphoma (DLBCL)/high grade B-cell lymphoma (HGBCL), marginal zone lymphoma or mantle cell lymphoma. The Phase 2 expansion phase is designed to evaluate the safety and efficacy of GDA-201 in two patient cohorts, FL and DLBCL/HGBCL. The study will include patients who have relapsed or refractory lymphoma after at least two prior treatments. For more information about the study, please visit www.clinicaltrials.gov (NCT03019666).
GDA-201 has been evaluated in a Phase 1 investigator-led study in patients with refractory non-Hodgkin lymphoma (NHL) and multiple myeloma, demonstrating that GDA-201 generally was well tolerated in 35 patients. Of the 19 patients with NHL, 13 complete responses and one partial response were observed (CRR = 68%, ORR = 74%). No dose-limiting toxicities were observed.
Two-year follow up data in the same Phase 1 study demonstrated an overall survival rate of 78% at two years, with a median duration response of 16 months (Bachanova, et al. ASH 2021. Abstract #3854).

About GDA-301
GDA-301 is an investigational genetically modified NAM-NK cell therapy candidate aimed at targeting hematologic malignancies and solid tumors. Preclinical data presented in a poster session, titled “GDA-301: Engineered NAM-NK Cells via CISH Knockout and Membrane-Bound IL-15 Expression Increases Cytotoxicity Against Malignancies,” demonstrated that after six hours of co-culture with a chronic myelogenous leukemia (K562) or multiple myeloma (RPMI) cell line, GDA-301, a combined genetic manipulation of CISH gene editing and the engineered expression of mb IL-15, showed increased cytotoxicity compared with control NAM-NK cells. Additional in vitro assays showed elevation of degranulation marker CD107a, and intracellular proinflammatory cytokines interferon-γ and tumor necrosis factor-α, suggesting increased potency of GDA-301 compared with control. The potency and cytotoxicity data suggest that GDA-301 represents a novel potential immunotherapeutic targeting hematologic malignancies as well as solid tumors.

About GDA-601
GDA-601 is an investigational genetically engineered NAM-NK cell therapy candidate designed to target multiple myeloma (MM) cells. Preclinical data presented in a poster session, titled “GDA-601: NAM-NK Cells With CD38 Knockout Expresses Enhanced CD38 Chimeric Antigen Receptor and Targets Multiple Myeloma Cells With Increased Cytotoxicity,” showed that in vitro killing assays performed six hours after co-culture of GDA-601 with a MM (RPMI) cell line showed increased cytotoxicity compared with control NAM-NK cells. Fratricide attributable to CD38 antigen was effectively eliminated with GDA-601. There was a significant enhancement of potency against CD38-positive MM cells demonstrated by elevation of the degranulation marker CD107a and intracellular proinflammatory cytokines interferon-γ and tumor necrosis factor-α in vitro. These results suggest that GDA-601 displays superior antitumoral responses against MM cells and represent a promising adoptive cell therapeutic strategy against MM.
PLATFORM
Gamida Cell is pioneering a diverse approach to cellular therapy that utilizes nicotinamide (NAM) to expand multiple cell types — including stem cells and natural killer (NK) cells — while maintaining their original phenotype and potency. When applied to umbilical cord blood–derived cells in the production of our investigational omidubicel product for allogeneic stem cell transplant, NAM-enabled cells have improved clinical measures such as engraftment time and infection rate, potentially leading to better outcomes for patients.
NK cells are cytotoxic lymphocytes of the innate immune system capable of killing virally infected and/or cancerous cells, and can be engineered using CAR and gene editing to increase targeting and activation. After expansion in culture however, NK cells typically lose some of their ability to traffic, localize and proliferate in vivo. This has been suggested as a major cause for the poor survival of adoptively transferred NK cells and their inability to overcome immune resistance in the tumor microenvironment. To address this obstacle, Gamida Cell has developed a reliable, scalable and GMP-compliant culture method for NAM expansion that yields highly functional NK cells. These cells have demonstrated ability to kill cancerous cells in both animal models and clinical trials, and are being developed in both unmodified and genetically engineered forms.
