- Allocation: Non-RandomizedIntervention Model: Sequential AssignmentIntervention Model Description: This study is conducted in two consecutive stages with 5 cohorts. A minimum of 28 days must separate each cohort. Within a 3 patient cohort, a minimum of 14 days must separate the first and second patient. Stage 1 Step 1 uses a fast-track design (1 patient per cohort) with a minimum of 28 days between each patient until one of the following: a) 1st occurrence of a pre-defined adverse event at which point the study moves to Step 2. The cohort size increases from 1 to 3 patients with 2 additional patients added. Escalation in Step 2 continues until the 1st DLT at which point Stage 2 continual reassessment method (CRM) is activated. If Cohort 5 is completed with 10 patients enrolled at the MTD without a DLT, Stage 2 (CRM) is not used. b) The 1st occurrence of a DLT the study moves directly to Stage 2 (CRM) and Step 2 is not used. c) Cohort 5 is completed without a pre-defined AE or a DLT - neither Step 2 nor Stage 2 is used if a total of 10 patients are enrolled in Cohort 5.Masking: None (Open Label)Primary Purpose: Treatment

FT516 is an off the shelf product comprised of allogeneic natural killer (NK) cells, expressing high-affinity non-cleavable CD16 (FT516). Enoblituzumab is an Fc-optimized monoclonal antibody that targets B7-H3 which is highly expressed on ovarian cancer. Based on data showing that within the ovarian cancer tumor microenvironment surface expression of CD16a on NK cells is diminished, the researchers hypothesize that the FT516 cellular product containing a non-cleavable CD16 will bypass the low CD16 expression issue and maximize NK cell cytotoxicity. Enoblituzumab is an Fc optimized humanized IgG1 monoclonal antibody that binds to B7-H3 (CD276). B7-H3 is an inhibitory immune checkpoint molecule that is widely expressed by a number of different tumor types and may play a key role in regulating the immune response. It is therefore hypothesized that the combination of FT516 with enoblituzumab will maximize NK cell cytotoxicity in patients with ovarian cancer.
