phase 1 trial of azd6422 in cldn18.2+ gi tumors

Conditions: Gastrointestinal Tumors

Summary: this is a ftih, phase 1 iit to evaluate the safety, feasibility, cellular kinetics (ck), pharmacodynamics (pd), immunogenicity, and preliminary antitumor activity of azd6422 in adult participants with advanced or metastatic cldn18.2+ gi tumors.

qualified researchers can request access to anonymized individual patient-level data from sponsor or the collaborator group of companies sponsored clinical trials via the request portal. all requests will be evaluated as per the sponsor disclosure commitment. yes, indicates that sponsors are accepting requests for ipd, but this does not mean all requests will be shared.
