Phase IIIa Study of AZD8205 Alone or Combined With Other Cancer Drugs in Adults With Advanced Solid Tumors

What this Trial Is About

Researchers are evaluating AZD8205, a new antibody drug conjugate, as a possible treatment for advanced or metastatic solid tumors including breast cancer, biliary tract cancer, ovarian, endometrial, and squamous non-small cell lung cancers. This Phase IIIa multi-center, open-label study aims to determine the safety, tolerability, and appropriate dosing of AZD8205 alone or combined with other anticancer agents such as rilvegostomig, saruparib, and AZD9574. The study includes dose escalation and expansion parts to assess anti-tumor activity in select solid tumors. Participants are assigned to one of four sub-studies that involve different combinations of AZD8205 with other drugs. Each sub-study has two parts Part A focuses on dose escalation to find safe doses, and Part B evaluates the anti-tumor effects at the recommended doses. Some sub-studies may add triplet combinations based on safety data and may include future protocol amendments. Treatment is given according to the assigned sub-study and dosing schedules. During the study, participants undergo assessments including monitoring for adverse events, serious adverse events, dose-limiting toxicities, and changes in laboratory tests, ECGs, and vital signs. Researchers also measure responses such as objective response rate, duration of response, progression-free survival, disease control rate, overall survival, pharmacokinetics, and immunogenicity over approximately two years. Study participation includes regular visits for treatment and evaluations, with safety follow-up until 30 days after the last dose.
