Experimental treatment for advanced solid tumors using AZD5863

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial evaluates the safety, tolerability, and anti-cancer activity of AZD5863, a T cell-engaging bispecific antibody targeting Claudin 18.2 and CD3, in adult patients with advanced or metastatic solid tumors. The study is structured in two modules: one administering AZD5863 intravenously and the other subcutaneously, with each module including dose-escalation and dose-expansion phases. Participants must have a confirmed diagnosis of specific adenocarcinomas and show positive expression of CLDN18.2 in their tumors.
