Phase 12 Study of BDC-4182 for Advanced Gastric and Gastroesophageal Cancer to Find Safe Dose and Evaluate Treatment

What this Trial Is About

Researchers are evaluating BDC-4182, an immune stimulating antibody conjugate, in people with advanced gastric and gastroesophageal cancers. This first-in-human dose escalation study aims to assess the safety and tolerability of BDC-4182 and to find the recommended dose for Phase 2. Participants have cancers that are metastatic or unresectable and have usually undergone prior standard treatments or are intolerant to them. Participants receive escalating doses of BDC-4182 until the maximum tolerated dose is found. Additional participants may join backfill cohorts at cleared dose levels to collect more safety data, followed by an expansion phase at the recommended dose. BDC-4182 consists of an anti-claudin 18.2 monoclonal antibody linked to a TLR 78 dual agonist, given as a single agent. During the study, participants have safety assessments including adverse event monitoring for about two years, with dose-limiting toxicities evaluated within 21 days of treatment. Effectiveness measures like tumor response rates, duration of response, disease control, progression-free and overall survival, and pharmacokinetics of the drug are tracked for up to four years. Biopsies or archival tumor samples are collected, and organ function is monitored. Participation lasts through dose escalation and expansion phases with ongoing safety and outcome evaluations.
