On April Gamida Cell Ltd. (Nasdaq: GMDA), the leader in the development of NAM-enabled cell therapies for patients with hematologic and solid cancers and other serious diseases, reported that the U.S. Food and Drug Administration (FDA) cleared its investigational new drug (IND) application and removed the clinical hold for a cryopreserved formulation of GDA-201 (Press release, Gamida Cell, APR 26, 2022, View Source [SID1234612985]). GDA-201 is an off-the-shelf cell therapy candidate for the treatment of patients with follicular and diffuse large B cell lymphomas. Gamida Cell expects to initiate a company-sponsored Phase 1/2 clinical study in patients with follicular and diffuse large B-cell lymphomas in 2022.

"FDA clearance of our IND for the cryopreserved formulation of GDA-201 represents a significant milestone for the company and reflects our team’s expertise in the development of NAM-enabled cell therapies," said Julian Adams, Ph.D., chief executive officer of Gamida Cell. "Previously announced data from an investigator-sponsored (IS) study evaluating the fresh formulation of GDA-201 demonstrated durable complete responses in heavily pretreated patients with relapsed or refractory lymphoma. We are pleased to advance our plans to begin the company sponsored Phase 1/2 study and progress our novel cryopreserved formulation of GDA-201 with objective to address the unmet need that exists for patients with follicular and diffuse large B cell lymphomas."
GDA-201 leverages Gamida Cell’s proprietary NAM technology platform to expand the number and functionality of NK cells to direct tumor cell killing properties and antibody-dependent cellular cytotoxicity (ADCC). In an investigator-sponsored Phase 1/2 study in patients with relapsed or refractory lymphoma, treatment with the fresh formulation of GDA-201 with rituximab demonstrated significant clinical activity. Of the 19 patients with non-Hodgkin lymphoma (NHL) , 13 complete responses and one partial response were observed, with an overall response rate of 74% and a complete response rate of 68%. At the December 2021 Annual Meeting of American Society of Hematology (ASH) (Free ASH Whitepaper), two-year follow-up data were reported on outcomes and cytokine biomarkers associated with survival. The data demonstrated a median duration of response of 16 months (range 5-36 months) and an overall survival at two years of 78% (95% CI, 51%–91%). In the IS study, GDA-201 was well-tolerated and no dose-limiting toxicities were observed in 19 patients with NHL and 16 patients with multiple myeloma. The most common Grade 3/4 adverse events were thrombocytopenia, hypertension, neutropenia, febrile neutropenia, and anemia. There was no incidents of cytokine release syndrome (CRS), neurotoxic events, GvHD or marrow aplasia.
About GDA-201
Gamida Cell applied the capabilities of its nicotinamide (NAM)-enabled cell expansion technology to develop GDA-201, an innate NK cell immunotherapy for the treatment of hematologic and solid tumors in combination with standard of care antibody therapies. GDA-201, the lead candidate in the NAM-enabled NK cell pipeline, has demonstrated promising initial clinical trial results. GDA-201 addresses key limitations of NK cells by increasing the cytotoxicity and in vivo retention and proliferation in the bone marrow and lymphoid organs. Furthermore, GDA-201 improves antibody-dependent cellular cytotoxicity (ADCC) and tumor targeting of NK cells.

GDA-201 is an investigational therapy, and its safety and efficacy have not been established by the FDA or any other health authority.
About NAM Technology
Our NAM-enabling technology, supported by positive Phase 3 data, 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.
