Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence of Dose-Limiting Toxicities (DLTs) Within Each Dose Level Cohort	The incidence of DLTs within each dose level cohort will be reported. A DLT is any adverse event (AE) that is at least possibly related to FT516 that occurs after the first FT516 infusion through the end of the DLT assessment period on Cycle 1 Day 29, and meets 1 of the criteria from the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0 or the American Society for Transplantation and Cellular Therapy (ASTCT) Consensus Grading Guidelines for Cytokine Release Syndrome and Neurological Toxicity Associated with Immune Effector Cells.	Up to Day 29 after the end of Cycle 1 (each cycle is 28 days)
Primary	Severity of DLTs Within Each Dose Level Cohort	The severity of DLTs within each cohort will be reported. DLT is any adverse event (AE) that is at least possibly related to FT516 that occurs after the first FT516 infusion through the end of the DLT assessment period on Cycle 1 Day 29, and meets 1 of the criteria from the NCI CTCAE v5.0 or the ASTCT Consensus Grading Guidelines for Cytokine Release Syndrome and Neurological Toxicity Associated with Immune Effector Cells.	At the end of Cycle 1 (each cycle is 28 days)
Secondary	Number of Participants with =1 Adverse Events (AE)	An AE is any untoward medical occurrence in a participants temporally associated with the use of study treatment, whether or not considered related to the study treatment.	Up to 15 years
Secondary	Investigator-Assessed Duration of Response (DOR)	DOR is the time from the first occurrence of a documented, objective response until the time of disease progression, relapse or death from any cause, whichever occurs first, per modified Response Evaluation Criteria in Solid Tumors (iRECIST) response criteria.	Up to 15 years
Secondary	Disease Control Rate (DCR)	DCR is defined as the percentage of participants with Stable Disease more than 6 months, Partial Response or Complete Response, per iRECIST response criteria.	Up to 15 years
Secondary	Progression Free Survival (PFS)	PFS is defined as the time from first dose of lympho-conditioning to disease progression or to the day of death for any reason, whichever occurs first, per iRECIST response criteria.	Up to 15 years
Secondary	Overall Survival (OS)	OS is defined as the time from first dose of lympho-conditioning to death from any cause.	Up to 15 years
Secondary	Determination of PK of FT516 in peripheral blood	The pharmacokinetics of FT516 in peripheral blood will be reported as the relative percentage of product (FT516) DNA versus patient DNA (% chimerism) measured from blood samples at the specified time points	Study Days 1, 2, 4, 8, 11, 18, 22, 29
