What this trial studies

This study evaluates the safety and tolerability of Autologous Tumor-Infiltrating Lymphocyte (GT307) injections in adults with solid tumors, specifically focusing on those with ovarian cancer that has progressed after initial chemotherapy. It is a single-arm, open-label design that aims to assess pharmacokinetics and efficacy to determine the optimal biological dose. Participants must meet specific eligibility criteria, including having measurable disease progression and a good performance status.

Why it matters

Potential benefit: If successful, this treatment could provide a new immunotherapy option for patients with advanced ovarian cancer.

How similar studies have gone: While similar immunotherapy approaches have shown promise in treating various cancers, this specific application of GT307 is novel and has not been extensively tested.
