Gamida Cell Presents Updated, Expanded Results from Phase 1 Study of Natural Killer Cell Therapy GDA-201 at ASH Annual Meeting and Exposition
—GDA-201 was well-tolerated and no dose-limiting toxicities were observed—
—GDA-201 demonstrated significant clinical activity in patients with non-Hodgkin lymphoma, with multiple complete responses observed—
—Phase 2 clinical trial of GDA-201 in non-Hodgkin lymphoma planned; IND submission anticipated in 2021—
GDA-201 was well-tolerated and no dose-limiting toxicities were observed in 35 patients (19 with NHL and 16 with MM). The data show that therapy using GDA-201 with monoclonal antibodies demonstrated significant clinical activity in heavily pretreated patients with advanced NHL. Of the 19 patients with NHL, 13 complete responses and one partial response were observed, with an overall response rate of 74 percent and a complete response rate of 68 percent. The maximum tolerated dose was not achieved, as no dose limiting toxicities were observed in patients who received the maximum target dose (2 x 108 cells/kg).
“Data from an expanded group of patients in this Phase 1 clinical study for GDA-201 show that NK cell therapies continue to exhibit impressive therapeutic potential to treat relapsed and refractory patients with lymphomas, while maintaining a favorable safety profile,” said Veronika Bachanova, M.D., Ph.D., Professor of Medicine in the
NK cell immunotherapies are thought to offer tremendous potential for transforming the care of hematologic malignancies. With GDA-201,
“These additional results again show that GDA-201 has striking signs of efficacy and safety in patients with heavily pre-treated NHL,” said
GDA-201 Phase 1 Clinical Data
The presentation, “Results of a Phase 1 Trial of GDA-201, Nicotinamide-Expanded Allogeneic Natural Killer (NK) Cells in Patients with Refractory Non-Hodgkin Lymphoma (NHL) and Multiple Myeloma,” described results from the Phase 1 clinical study of GDA-201 in heavily pre-treated patients with advanced NHL and MM. Preliminary results from this study were presented at the 2019 ASH Annual Meeting.
In the study, cell therapy using GDA-201 with monoclonal antibodies was shown to be safe; there were no dose-limiting toxicities, neurotoxic events, confirmed cytokine release syndrome, graft versus host disease or marrow aplasia. Overall survival and progression-free survival at one year in the NHL cohort suggest durable disease control, with a median follow-up of ten months (range 1–28 months). The most common adverse events were decreased neutrophil count, febrile neutropenia, anemia and low platelet counts.
In the NHL cohort, durable complete responses were observed in patients with both follicular and diffuse large B cell lymphoma, with an overall response rate of 74 percent. Future development of GDA-201 may include cryopreservation and the exploration of multiple treatment cycles in a multi-center Phase 2 trial in patients with NHL.
GDA-201 is an investigational therapy, and its safety and efficacy have not been established by the
About the NAM Therapeutic Platform
Gamida Cell’s proprietary NAM-based cell expansion platform is designed to enhance the number and functionality of donor cells in culture, enabling the creation of potentially transformative therapies that move beyond what is possible with existing approaches. The NAM therapeutic platform leverages the unique properties of nicotinamide to enable the expansion of multiple cell types — including stem cells and natural killer (NK) cells — with appropriate growth factors to maintain the cells' original phenotype and potency. This can enable the administration of a therapeutic dose of cells with the potential to improve patient outcomes.
