Study of AZD5863 in Adult Participants With Advanced or Metastatic Solid Tumors

Summary

This research is designed to determine if experimental treatment with AZD5863, a T cell-engaging bispecific antibody that targets Claudin 18.2 (CLDN18.2) and CD3, is safe, tolerable and has anti-cancer activity in patients with advanced solid tumors.
