About this trial

This is a single-arm, open-label, dose-escalation clinical trial designed to evaluate the safety, tolerability, expansion, and persistence of TC-G203 in patients with GPC3-positive recurrent or metastatic solid tumors who have progressed after prior therapies. The primary objective is to determine the maximum tolerated dose (MTD), with a secondary aim to assess preliminary clinical efficacy in solid tumors.

Trial outcomes

Primary outcomes

1

Incidence of Dose-Limiting Toxicities (DLT) and Maximum Tolerated Dose (MTD)

DLT is defined as any CAR-T cell-related adverse event graded per ASTCT 2019 CRS criteria and NCI CTCAE v5.0, including: ≥Grade 4 hematologic toxicity not recovering to ≤Grade 2 by Day 28, ≥Grade 4 CRS lasting ≥3 days, ≥Grade 3 ICANS, or ≥Grade 3 non-hematologic toxicity lasting \>7 days (excluding fever, fatigue, nausea/vomiting).

Time frame
Within 28 days after TC-G203 infusion

Secondary outcomes

Objective Response Rate (ORR): Number of participants with complete response (CR) or partial response (PR) Duration of Response (DOR): Time from first documented response to disease progression or death Progression-Free Survival (PFS): Time from TC-G203 infusion to disease progression or death Overall Survival (OS): Time from TC-G203 infusion to death from any cause

Time frame
Up to 24 months

Other outcomes

1
