A Phase 1, Open-Label Study Investigating the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Preliminary Antitumor Activity of BGB-B455 in Patients With Selected Advanced or Metastatic Solid Tumors
BeiGene
Summary
The goal of this clinical trial is to learn if BGB-B455 can treat advanced or metastatic solid tumors expressing claudin 6 (CLDN6), a protein that is found on some tumors. The main questions it aims to answer are: * What is the recommended dosing for BGB-B455? * What medical problems do participants have when taking BGB-B455? The study has two parts: * Phase 1a: dose escalation and safety expansion * Phase 1b: dose expansion
Description
Claudin proteins are cell proteins that can play an important role in how cancer starts and progresses. Because of its preferential expression in tumors compared to normal tissues, CLDN6 is an ideal tumor antigen to target for treatment. BGB-B455 is a bispecific antibody (BsAbs) that targets CLDN6 on tumor cells and the CD3 receptor on T cells, which may provide a CLDN6-dependent antitumor immune response in a more tolerable manner without undue systemic toxicity. This new study will check how safe and helpful this potential anticancer drug is. In addition, this study will explore the recomme…
