TC-G203 treatment for GPC3-positive advanced solid tumors

Official title: A Preliminary Clinical Study of TC-G203 for Patients With GPC3-Positive Recurrent/Metastatic Solid Tumors

Run by Beijing GoBroad Hospital · NCT07242417 · Data updated 2026-11-12

This trial will test a single-dose TC-G203 cell therapy to see if it is safe and helps adults with GPC3-positive recurrent or metastatic solid tumors who have already tried other treatments.

Is this trial a fit for you?

Likely a good fit

Adults 18–75 years with GPC3-positive recurrent or metastatic solid tumors, ECOG 0–1, measurable disease, adequate organ and marrow function, who have failed or are unsuitable for standard therapy and can undergo leukapheresis and lymphodepletion.

Probably not a fit

Patients with GPC3-negative tumors, uncontrolled CNS metastases, active infections, autoimmune disease, significant cardiac disease, immunodeficiency, recent other malignancies, pregnancy, or inability to undergo leukapheresis or lymphodepletion are unlikely to benefit or be eligible.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a single-arm, open-label, early-phase dose-escalation trial of a one-time TC-G203 cell infusion for patients with GPC3-positive recurrent or metastatic solid tumors. The protocol includes screening, leukapheresis to collect peripheral blood mononuclear cells, lymphodepletion chemotherapy, TC-G203 infusion, and close post-infusion follow-up. Doses will be escalated to determine the maximum tolerated dose while monitoring safety, tolerability, and in vivo expansion and persistence of the infused cells. Secondary measures include preliminary anti-tumor activity by RECIST and correlative biomarker analyses.

Why it matters

Potential benefit: If successful, TC-G203 could provide a new cell-therapy option that produces durable tumor responses for patients with GPC3-positive tumors who have exhausted standard treatments.

How similar studies have gone: Early-phase trials of GPC3-targeted cellular therapies and other CAR-T approaches in hepatocellular carcinoma have shown limited but promising anti-tumor signals, though durable benefit in solid tumors remains unproven.
