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.

Interventions

• AZD5863 · DRUG

  T cell-engaging bi-specific antibody that targets CLDN18.2 (Claudin18.2) on tumor cells and CD3 on T cells

• AZD2936 · DRUG

  Rilvegostomig is a bi-specific antibody targeting the immunosuppressive PD-1 and TIGIT pathways.
