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

Sponsor: ImmunityBio, Inc.

View on ClinicalTrials.gov

Summary

QUILT-3.055 is a Phase 2b, open-label, multicohort study investigating combination immunotherapies in patients with advanced solid tumors who have previously been treated with PD-1/PD-L1 checkpoint inhibitors. The study aims to evaluate the safety and efficacy of NAI (nogapendekin alfa inbakicept) in combination with other agents like checkpoint inhibitors and cell therapies across various cancer types and treatment settings. The study includes multiple cohorts based on prior therapies and cancer types, with a focus on assessing overall response rate (ORR), overall survival (OS), and other measures of anti-tumor activity and immune response.
