Phase 1a/1b Study of TPST-1495 as a Single Agent and in Combination With Pembrolizumab in Subjects With Solid Tumors

Completed · Phase 1

Conditions studied: Solid Tumor, Colorectal Cancer, Non Small Cell Lung Cancer, Squamous Cell Carcinoma of Head and Neck, Urothelial Carcinoma, Endometrial Cancer, Gastroesophageal Junction Adenocarcinoma, Gastric Adenocarcinoma, Solid Tumors With PIK3Ca Mutation

In brief

This is a first-in-human Phase 1a/1b, multicenter, open-label, dose-escalation, dose and schedule optimization, and expansion study of TPST-1495 as a single agent and in combination with pembrolizumab to determine its maximum tolerated dose (MTD) and or recommended Phase 2 dose (RP2D), safety, tolerability, pharmacokinetics, pharmacodynamics and preliminary anti-tumor activity in subjects with advanced solid tumors. Subjects with all histologic types of solid tumors are eligible for the escalation and dose-finding portions of the study. However, the preferred tumor types for enrollment are colorectal cancer (CRC), non-small cell lung cancer (NSCLC), squamous cell carcinoma of the head and neck (SCCHN), urothelial cancer, endometrial cancer, and gastroesophageal junction (GEJ) or gastric adenocarcinoma. Enrollment in the expansion cohorts is limited to the following tumor types: endometrial, SCCHN, CRC, and a basket cohort in subjects selected for an activating mutation in PIK3Ca.
