QUILT-3.055: a Study of Combination Immunotherapies in Patients Who Have Previously Received Treatment with Immune Checkpoint Inhibitors

Description

This Phase 2b, multicohort, open-label clinical trial (QUILT-3.055) evaluates combination immunotherapies in patients with various advanced solid tumors who have progressed following prior PD-1/PD-L1 checkpoint inhibitor therapy. The trial includes six cohorts: Cohorts 1-4: Patients who progressed after an initial response (PR or CR) to prior PD-1/PD-L1 therapy, receiving combination therapy with N-803 and a PD-1/PD-L1 checkpoint inhibitor. (Closed to enrollment) Cohort 5: Patients who progressed while receiving treatment in cohorts 1-4; they receive combination therapy with N-803, a PD-1/PD-L1 checkpoint inhibitor, and PD-L1 t-haNK cells.(Closed to enrollment) Cohort 6A \& 6B: Patients with acquired resistance to prior PD-1/PD-L1 therapy; they receive combination therapy with N-803, docetaxel, and either pembrolizumab (6A) or nivolumab (6B). Treatment is administered for up to two years or until disease progression, and participants are closely monitored for adverse events (AEs), including immune-related AEs, with specific dose modifications outlined. The primary endpoint is objective response rate (ORR) assessed by RECIST v1.1. The study uses Simon's two-stage design for cohorts 1-3 to determine the optimal dose and further assesses safety and efficacy endpoints for all cohorts.

Conditions
