Gamida Cell Presents New Data from NAM-Enabled Genetically Modified Natural Killer (NK) Pipeline at International Society for Cell & Gene Therapy 2022

• Poster selected for inclusion in conference’s Elevator Pitch Session: GDA-301 produces enhanced potency and persistence with combined genetic manipulation of CISH gene editing and the engineered expression of membrane-bound IL-15 for targeting hematologic malignancies and solid tumors
• GDA-601 generates promising immunotherapeutic potential to target multiple myeloma cells
• Company plans to select a genetically modified NK cell therapy candidate for IND enabling study by the end of 2022

Excerpt from the Press Release:

BOSTON–(BUSINESS WIRE)–Gamida Cell Ltd. (Nasdaq: GMDA), the leader in the development of NAM-enabled cell therapies for patients with solid and hematological cancers and other serious diseases, today will share preclinical data at the International Society for Cell & Gene Therapy (ISCT) 2022, being held in San Francisco, CA, May 4-7, 2022 on GDA-301 and GDA-601, two product candidates in the Company’s NAM-enabled genetically modified natural killer (NK) pipeline.

“The preclinical data generated from our expanding pipeline of NAM-enabled cell therapies is already showing signs of meaningful potential as a future approach to fighting cancer,” said Julian Adams, Ph.D., Chief Executive Officer of Gamida Cell. “With evidence of enhanced cytotoxicity demonstrated across hematologic cancers and solid tumors with these diverse, genetically modified NK cell immunotherapy programs, we look forward to continuing our progress toward opening new frontiers in cancer immunotherapy.”

GDA-301 is an investigational genetically modified NAM-NK cell therapy candidate aimed at targeting hematologic malignancies and solid tumors. The poster (#501), 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.
