What this Trial Is About

Researchers are evaluating the bispecific antibody MCLA-158 in patients with advanced solid tumors, including metastatic colorectal cancer (mCRC) and head and neck squamous cell carcinoma (HNSCC). This Phase 1/2 open-label study aims to determine the recommended dose for further testing and assess the safety, tolerability, pharmacokinetics, pharmacodynamics, immunogenicity, and anti-tumor activity of MCLA-158 alone or combined with other treatments. The study includes patients with tumors showing dependence on EGFR signaling. The study has two parts: a completed dose escalation phase to find the recommended Phase II dose (RP2D) of MCLA-158, and a dose expansion phase to evaluate safety and activity at the RP2D of 1500 mg every two weeks. Patients receive MCLA-158 by intravenous infusion every 14 days in 28-day cycles. The expansion phase includes single-agent cohorts for various tumor types and combination cohorts where MCLA-158 is tested with pembrolizumab or chemotherapy regimens FOLFIRI or FOLFOX in specific colorectal cancer settings. Participants undergo regular assessments including monitoring for side effects, response to treatment, and laboratory tests such as blood work and heart function scans. Researchers measure outcomes like dose-limiting toxicities, overall response rates, treatment modifications due to adverse events, and survival over periods ranging from weeks up to 36 months. The study also evaluates drug levels in the body and immune responses during treatment. Total participation duration varies with each patient's treatment course and follow-up.
