GT201 injection for advanced solid tumors

A Single-Arm Phase I/II Clinical Study of Autologous Tumor-Infiltrating Lymphocyte Injection (GT201) for The Treatment Of Advanced Solid Tumors

PHASE1; PHASE2 · Grit Biotechnology · NCT06144671

This study is testing a new injection called GT201 to see if it can safely help people with advanced solid tumors who haven't had any local treatments before.

What this trial studies

This clinical trial evaluates the safety and efficacy of GT201 injection in patients with advanced solid tumors. It employs a modified '3+3' dose-escalation design, which includes both accelerated dose escalation and traditional methods. The trial aims to enroll 7 to 18 evaluable subjects across three dose groups, with the first group undergoing accelerated titration and the subsequent groups following the traditional escalation principle. The study focuses on patients with resectable lesions who have not received prior local therapies.

Who should consider this trial

Good fit: Ideal candidates are adults with a confirmed diagnosis of advanced solid tumors and at least one resectable lesion.

Not a fit: Patients with active autoimmune diseases or those who 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 advanced solid tumors.

How similar studies have performed: Other studies utilizing similar dose-escalation approaches have shown promise, but this specific treatment is novel.
