Description

Summary

The purpose of this study is to characterize the safety, tolerability, pharmacokinetics, pharmacodynamics and preliminary antitumor activity of DRP-104 administered via intravenous infusion as a single agent and in combination with atezolizumab in patients with advanced solid tumors and to assess preliminary safety and efficacy in two expansions of patients, advanced non-small cell lung cancer (NSCLC) with defined genetic mutations and advanced squamous cell carcinoma of the head and neck (SCCHN).

Official Title

Phase 1 and Phase 2a, First-in-human Study of DRP-104, a Glutamine Antagonist, in Adult Patients With Advanced Solid Tumors

Details

This study will be conducted in 4 Parts: Part 1: Phase 1 single-agent dose escalation of DRP-104 in patients with advanced solid tumors to define the MTD (up to approximately 50 patients) Part 2, Once the MTD of DRP-104 has been declared and includes 3 specific cohorts: - Cohort 1: Phase 1 single-agent safety expansion at the of DRP-104 in patients with advanced solid tumors (N=14 patients); - Cohort 2: Phase 2a expansion at the of DRP-104 in patients with locally advanced or metastatic NSCLC whose tumors contain a KEAP1 mutation, NFE2L2 mutation and/or STK11 mutation (N=55 patients) - Cohort 3: Phase 2a expansion at the MTD of DRP-104 in recurrent, unresectable or metastatic SCCHN (N=15-25 patients). Part 3: Phase 1 combination dose escalation of DRP-104 and atezolizumab in patients with advanced solid tumors previously treated with an anti-PD-1, anti PD-L1, and/or anti-CTLA-4 antibody, starting one dose level below the MTD of single-agent DRP-104 and in combination with atezolizumab (up to approximately N=12 patients). Part 4: Phase 1 combination safety expansion at the MTD of DRP-104 with atezolizumab in a similar patient population as the dose-escalation (N=14 patients).
