Study of Sacituzumab Govitecan-hziy (IMMU-132) in Adults With Epithelial Cancer

August 10, 2021 updated by: Gilead Sciences

A Phase I/II Study of IMMU-132 (hRS7-SN38 Antibody Drug Conjugate) in Patients With Epithelial Cancer

The primary objective in Phase I is to evaluate the safety and tolerability of sacituzumab govitecan-hziy (SG) as a single agent administered in 21-day treatment cycles in previously treated participants with advanced epithelial cancer. In Phase II, the primary objective is to evaluate the safety and efficacy of sacituzumab govitecan-hziy administered in 21-day treatment cycles at a dose selected in Phase I.

Tumor types in the study will include: cervical, colorectal, endometrial, ovarian, esophageal, gastric adenocarcinoma, glioblastoma multiforme, head and neck cancers- squamous cell, hepatocellular, prostate, non-small-cell lung cancer, pancreatic, renal cell, small-cell lung cancer, non-triple negative breast cancer (non-TNBC), triple-negative breast cancer (TNBC) and metastatic urothelial cancer (mUC).

Detailed Description

The outcome measures are planned to be assessed up to the data cutoff date. Following the data cutoff date, the participants will either stay on the study and will be followed for safety data collection or rolled into another Gilead-sponsored study. Therefore, only safety data will be collected after the data cutoff date.
