Phase 1/2 Dose Escalation and Expansion Study Evaluating MCLA-129, a Human Anti-EGFR and Anti-c-MET Bispecific Antibody, in Patients With Advanced NSCLC and Other Solid Tumors
A phase 1/2 open-label multicenter study will be performed with an initial dose escalation part to determine the MTD and/or the RP2D of MCLA-129 in monotherapy or in combination in patients with NSCLC, HNSCC, GC/GEJ, ESCC, or other solid tumors and who are treatment naïve or have progressed after receiving prior therapy for advanced/metastatic disease.
⁃ Part One: Patients with NSCLC, GC/GEJ, HNSCC, or ESCC who have failed prior standard first-line treatment. Patients must have progressed on or be intolerant to therapies that are known to provide clinical benefit. There is no limit to the number of prior treatment regimens.
⁃ Part Two: Patients with NSCLC, HNSCC, other solid tumors and applicable mutations as determined by the investigator.
