Phase III Study of BNT3212 Alone or With Pumitamig for Safety and Early Effectiveness in Adults With Advanced Solid Tumors

What this Trial Is About

Researchers are evaluating the safety, tolerability, pharmacokinetics, immune response, and early clinical effects of BNT3212, both alone and combined with pumitamig, in adults with advanced solid tumors who have exhausted other treatment options. This first-in-human, open-label study includes dose escalation and expansion phases to find the best dose and assess how the treatments work across different tumor types. The study is divided into four parts Part A and Part B focus on BNT3212 as a single therapy, with dose escalation followed by dose expansion in specific tumor types. Parts C and D evaluate the combination of BNT3212 with a fixed dose of pumitamig, again starting with dose escalation and then expansion cohorts. Treatments are given by intravenous infusion, and doses are adjusted to find the maximum tolerated dose and recommended dose for further study. Participants will undergo regular monitoring including safety assessments, blood tests to study drug levels and immune reactions, and imaging to measure tumor response. Researchers will track side effects, treatment interruptions, and response rates over approximately 31 months. The study also measures progression-free and overall survival. Continuous evaluation of safety and clinical data supports participant well-being throughout the trial.
