Summary

This trial tests DRP-104, a new cancer drug, alone and with atezolizumab, an immune-boosting drug, in patients with advanced solid tumors, especially those with specific genetic mutations. DRP-104 aims to kill cancer cells directly, while atezolizumab helps the immune system fight the cancer.

Trial Design

4Treatment groups

Experimental Treatment

Group I: Part 4Experimental Treatment2 Interventions

Phase 1 combination safety expansion at the MTD/MAD/RP2D, route, and schedule of administration of DRP-104 with atezolizumab in a similar patient population as the dose-escalation (N=14 patients).

Group II: Part 3Experimental Treatment2 Interventions

Phase 1 combination dose escalation of DRP-104 and atezolizumab in patients with advanced solid tumors (excluding primary CNS tumors and HCC) previously treated with an agent targeting checkpoint pathway inhibition (such as anti-PD-1, anti-PD-L1, and/or anti-CTLA-4 antibody), starting one dose level below the MTD/MAD/RP2D (MTD-1) of the recommended phase 2 route and schedule of administration of singleagent DRP-104 and in combination with 1200 mg atezolizumab administered via intravenous infusion on day 1 and repeated every 3 weeks (up to approximately 12 patients);

Group III: Part 2Experimental Treatment1 Intervention

Cohort 1: Phase 1 single-agent safety expansion of DRP-104 administered subQ (the RP2R) in patients with advanced solid tumors (excluding primary CNS tumors and HCC). DRP-104 will be administered twice weekly subQ in this safety expansion at the twice weekly subQ MTD/MAD/RP2D of DRP-104 determined in Part 1-Cohort 1b. A minimum of 14 and up to 20 patients will be enrolled. Cohort 2: Phase 2a expansion at the MTD/MAD/RP2D/RP2R and schedule of administration (subQ twice or thrice weekly) of DRP-104 in patients with locally advanced or metastatic NSCLC whose tumors contain a known mutation in kelchlike ECH-associated protein 1 (KEAP1), nuclear factor erythroid 2-related factor 2 (NFE2L2) and/or serine/threonine kinase 11 (STK11), (N=55). If the thrice weekly schedule is selected as the RP2S, a safety review will be conducted after 8 patients have enrolled and are followed for at least one cycle of treatment before additional patients are enrolled into Part 2-Cohort 2.

Group IV: Part 1a & Part 1bExperimental Treatment1 Intervention

Single-agent dose escalation of DRP-104 to define the MTD (up to approximately 50 patients) starting at Dose Level 1 of 3.3 mg/m2 via intravenous injection Single-agent dose escalation of DRP-104 to define the MTD (up to approximately 50 patients) starting at Dose Level 1 at 10 mg via subcutaneous injection
