Current Primary Outcome Measures (submitted: August 10, 2021)

• Percentage of Participants Experiencing Any Treatment Emergent Adverse Events and Serious Treatment Emergent Adverse Events [ Time Frame: First dose date up to last dose for data cutoff date of 01 March 2019 (maximum duration: 55.2 months) plus 30 days ]
  Treatment-emergent adverse events (TEAEs) were defined as any adverse events (AEs) that begin or worsen on or after the start of study drug through 30 days after the last dose of study drug. The severity was graded based on the National Cancer Institute's Common Terminology Criteria for Adverse Events Version 4.03. An AE that met one or more of the following outcomes was classified as serious:

  • Fatal
  • Life-threatening
  • Disabling/incapacitating
  • Results in hospitalization or prolongs a hospital stay
  • A congenital abnormality
  • Other important medical events may also be considered serious AEs if they may require medical or surgical intervention to prevent one of the outcomes listed above

  Per planned analysis, populations to be used for evaluation of this outcome measure were as follows: Triple Negative Breast Cancer (TNBC) Target Population, HR+/HER2- Metastatic Breast Cancer (mBC) Population, Metastatic Urothelial Cancer (mUC) Population, and Overall Safety Population.

CR was defined as the disappearance of all target lesions and reduction in short axis of any pathologic lymphnode to <10 mm. PR was defined as ≥ 30% decrease in the sum of diameters of target lesions, taking the baseline sum diameters. Per planned analysis, ORR by ICR was assessed for the TNBC Target Population only.
• Objective Response Rate by Local Assessment [ Time Frame: Up to data cutoff date of 01 March 2019 (maximum duration: 74 months) ]
  ORR was defined as the rate an overall best response of either complete response (CR) or partial response (PR) by local assessment. CR was defined as the disappearance of all target lesions and reduction in short axis of any pathologic lymphnode to <10 mm. PR was defined as ≥3 0% decrease in the sum of diameters of target lesions, taking the baseline sum diameters. Per planned analysis, ORR by Local Assessment was assessed for TNBC Target Population, HR+/HER2-mBC Population, and mUC Population.

Descriptive Information

• Brief Title: Study of Sacituzumab Govitecan-hziy (IMMU-132) in Adults With Epithelial Cancer
• Official Title: A Phase I/II Study of IMMU-132 (hRS7-SN38 Antibody Drug Conjugate) in Patients With Epithelial Cancer

Brief Summary

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.
