Injection of immune cells to treat advanced solid tumors

Single-center, Single-arm Phase I Clinical Study of Autologous Tumor-infiltrating Lymphocyte Injection (GT201) for the Treatment of Metastatic/recurrent Advanced Solid Tumors

Phase 1 Interventional Grit Biotechnology · NCT05430360

This study is testing a new treatment that uses immune cells from patients' own tumors to see if it can help people with advanced solid tumors feel better.

What this trial studies

This phase I clinical trial evaluates the safety and efficacy of autologous tumor-infiltrating lymphocyte therapy for patients with metastatic or recurrent advanced solid tumors. The approach involves a regimen of lymphodepleting chemotherapy followed by the infusion of autologous tumor-infiltrating lymphocytes and interleukin-2. The study will enroll 30 subjects, with a focus on those who have accessible tumor tissue for lymphocyte preparation. Participants will undergo a structured process including screening, treatment, and follow-up periods.

Who should consider this trial

Good fit: Ideal candidates are patients with metastatic or recurrent advanced solid tumors who have accessible tumor tissue and an ECOG performance status of 0 or 1.

Not a fit: Patients with uncontrolled tumor-related pain, significant respiratory diseases, or those who have not responded to prior surgeries or radiation therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could provide a novel treatment option for patients with advanced solid tumors who have limited treatment alternatives.

How similar studies have performed: While this approach is being explored in various contexts, the specific application of autologous tumor-infiltrating lymphocyte therapy in this manner is relatively novel.
