What this trial studies

This multicenter, single-arm phase I clinical trial aims to evaluate the safety and efficacy of GT101, an autologous tumor-infiltrating lymphocyte therapy, for patients with unresectable recurrent or metastatic solid tumors. The study involves a screening period, lymphodepleting chemotherapy, GT101 infusion, and post-infusion treatment with interleukin-2. A total of 20-31 subjects will be enrolled, with 14-20 expected to be evaluable for treatment outcomes. The trial will assess the response of the tumors to this innovative therapy.

Who should consider this trial

Good fit: Ideal candidates include adults with unresectable recurrent or metastatic solid tumors who have at least one resectable lesion for lymphocyte preparation.

Not a fit: Patients with solid tumors that are resectable or have received prior local therapies may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat metastatic or recurrent solid tumors.

How similar studies have performed: While this approach is innovative, similar therapies have shown promise in other studies, indicating potential for success.
