About

This is a Phase I study of FT596 in combination with two different schedules (standard or alternate) of R-CHOP in subjects with B-cell lymphoma who are previously untreated or have received no more than one prior line of treatment. The study will consist of a dose-escalation stage followed by a dose-expansion stage.

Full description

This is a Phase I study of FT596 in combination with 2 different schedules (standard or alternate) of R-CHOP in subjects with B-cell lymphoma who are previously untreated or have received no more than one prior line of treatment.

The study will evaluate both the clinical benefit of FT596 when combined with R-CHOP given on a standard or alternate schedule.

Subjects will be enrolled in two stages: a dose-escalation stage and a dose-expansion stage. After safety and tolerability have been assessed to define the maximum tolerated dose (MTD) (or the maximum assessed dose [MAD] in the absence of dose limiting toxicities [DLTs] defining the MTD) in the dose-escalation stage, the dose-expansion stage will further evaluate the safety and activity of FT596 in combination.
