A Study of CLSP 5282 in HLA-A*03:01 Positive Adult Patients With Solid Tumors (SENTINEL-101)

Sponsored by Clasp Therapeutics, Inc.

About this study

Phase 1, open-label, multicenter study to evaluate the safety, tolerability, PK, PD, and preliminary clinical activity of CLSP 5282 when administered to HLA A\*03:01-positive adult patients with advanced solid tumors that harbor the KRas G12V mutation.

CLSP-5282-101 is a Phase 1, open-label, multicenter study designed to evaluate the safety, tolerability, PK, PD, and preliminary clinical activity of CLSP-5282 when administered to HLA A\*03:01-positive adult patients with advanced solid tumors that harbor the KRas G12V mutation. The study will be conducted in 2 parts: Part A Monotherapy Dose Escalation to determine the MTD and/or RDE(s) to characterize safety and clinical activity of CLSP-5282. Part B Monotherapy Expansion to explore the preliminary antitumor activity and further characterize the safety, tolerability, PK, and PD of CLSP-5282 at the RDE(s). Part B will include three indication-specific cohorts in pancreatic adenocarcinoma (PDAC), colorectal cancer (CRC), and non-small cell lung carcinoma (NSCLC) as well as an all-other …
