Gamida Cell Presents Data on its NAM-Enabled NK Cell Therapies at Protein & Antibody Engineering Summit (PEGS) Europe

Gamida Cell Ltd. (Nasdaq: GMDA), an advanced cell therapy company committed to cures for cancer and other serious diseases, today announced that Aviad Pato, Ph.D., Head of Immunology Research, presented data on two nicotinamide (NAM)-enabled NK cell therapies, GDA-501 and GDA-301, at the Protein & Antibody Engineering Summit (PEGS) Europe taking place in Barcelona, Spain, and virtually November 2-4, 2021.

The presentation included data from early-stage studies of GDA-501, Gamida Cell’s investigational cell therapy comprised of CAR-engineered NK cells designed to enhance homing and activation against cancers with HER2 overexpression such as breast, ovarian, lung, bladder, and gastric cancers. Data were also presented on GDA-301, which combines a CRISPR/Cas9 knockout of the CISH (cytokine inducible SH2 containing protein) gene in NK cells with a membrane-bound IL-15/IL-15Ra CAR, which is designed to improve tumor killing by promoting activation and inhibiting negative feedback signals and has potential application in a range of solid tumors and hematologic malignancies.

Data presented by Gamida Cell demonstrated that the engineered GDA-501 NK enhances potency and cytotoxicity against a HER2-expressing tumor cell line. Data also showed that GDA-301 has cytotoxic activity against a chronic myelogenous leukemia cell line (K562) and a multiple myeloma cell line (RPMI).

“The field of NK cell immunotherapy is advancing beyond what has previously been understood from T cell gene editing,” said Yona Geffen, Ph.D., Vice President, Research and Development at Gamida Cell. “We are pleased to share this important update on two key potential therapies in Gamida Cell’s robust NK pipeline that show their potential as clinical immunotherapy agents.”

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.
