This study uses a single dose of the investigational product FT596 in the early post-transplant period. Rituximab or an FDA approved by biosimilar including Rituxan®, Truxima®, and Ruxience™ is given 48 to 72 hours prior to FT596. The goal of this study is to 1) establish a maximum tolerated dose (MTD) of FT596 when given 30 days after transplant and 2) to confirm the MTD and safety of giving a single dose of FT596 at Day 7 post-transplant starting at one dose level below the MTD identified at Day 30.
This is a Phase I multi-center study to evaluate the safety of FT596 when given with rituximab as relapse prevention in patients who have undergone an autologous hematopoietic stem cell transplant (auto-HSCT) for diffuse large or high-grade B cell lymphoma.
