Interim Phase I Clinical Data of FT576 As Monotherapy and in Combination with Daratumumab in Subjects with Relapsed/Refractory Multiple Myeloma
Results: As of a data cutoff date of 18 Jul 2022, 9 patients with R/R MM were treated and evaluable for safety and efficacy, in the first 2 dose levels of Regimen A (n = 6) and in the first dose level of Regimen B (n = 3). No dose-limiting toxicities, and no events of any grade of cytokine release syndrome (CRS), immune effector cell-associated neurotoxicity syndrome, or graft-versus-host disease (GvHD), were observed.
Conclusions: Administration of a single dose of FT576 at 100 or 300 million cells/dose alone or in combination with daratumumab is safe and well tolerated thus far without CRS, neurotoxicity, or GvHD. Interim clinical data, including safety and tolerability and initial anti-tumor activity, from the ongoing Phase I dose-escalation study of FT576 will be presented at the conference.
