Breast Cancer Clinical Trial
FT538 in Combination With Monoclonal Antibodies in Advanced Solid Tumors
This is a Phase 1 dose-finding study of FT538 in combination with monoclonal antibodies.
This is a Phase 1 dose-finding study of FT538 given in combination with a monoclonal antibody following lymphodepletion in subjects with advanced solid tumors. The study will consist of a dose-escalation stage and an expansion stage where participants will be enrolled into indication-specific cohorts.
Subjects with locally advanced or metastatic disease who have progressed after at least one line of therapy and diagnosis of one of the following by treatment cohort:
Cohort A: The following solid tumor malignancies where anti-PD-1/PD-L1 antibodies are approved: cutaneous melanoma, non-small cell/small cell lung cancer, renal cell carcinoma, head and neck squamous cell cancer, microsatellite instability-high/ mismatch repair deficient cancer, gastric cancer, esophageal cancer, cervical cancer, merkel cell carcinoma, endometrial carcinoma, tumor mutation burden-high ≥ 10 mutations/megabase], cutaneous squamous cell carcinoma, triple-negative breast cancer.
Cohort B: HER2+ breast cancer that has relapsed or progressed on trastuzumab and progressed on either pertuzumab or HER2-targeting antibody drug conjugate; HER2+ gastric cancer that has relapsed or progressed on trastuzumab-containing therapy; OR any other HER2+ solid tumor having progressed on at least one line of standard-of-care therapy. For any tumor type in this cohort, HER2 status must be documented by a U.S. Food and Administration (FDA) approved test to be ≥2+ IHC or Average HER2 copy number ≥4 signals per cell by in situ hybridization.
Cohort C: CRC having progressed following prior cetuximab treatment or has KRAS/NRAS mutation; HNSCC having progressed following prior cetuximab.
