Brief summary

This is a Phase I dose-finding study of FT819 as monotherapy and in combination with IL-2 in subjects with relapsed/refractory B-cell Lymphoma, Chronic Lymphocytic Leukemia and Precursor B-cell Acute Lymphoblastic Leukemia. The study will consist of a dose-escalation stage and an expansion stage where participants will be enrolled into indication-specific cohorts.

Design outcomes

Primary

MeasureTime frame
Incidence and nature of dose-limiting toxicities within each dose level cohortUp to Day 29

Secondary

MeasureTime frameDescription
Investigator-assessed objective-response rate (ORR)Up to approximately 2 years after last dose of FT819
For BCL and CLL Only: Investigator-assessed duration of objective response (DOR)Up to 15 years
For BCL and CLL Only: Investigator-assessed duration of complete response (DoCR)Up to 15 years
For BCL and CLL Only: Progression-free survival (PFS)Up to 15 years
Overall survival (OS)Up to 15 years
Determination of the pharmacokinetics of FT819 cells in peripheral blood.Study Days 1, 2, 3, 4, 5, 8, 11, 15, 22, and 29The PK of FT819 in peripheral blood will be reported as the relative percentage of product (FT819) DNA versus patient DNA (% chimerism) measured from blood samples at the specified time points
For B-ALL Only: Investigator-assessed relapse-free survival (RFS)Up to 15 years
