Evaluating AST-201 for GPC3-positive advanced solid tumors
Official title: A Multi-center, Open-label, Dose Escalation and Expansion, Phase 1 Study to Evaluate the Tolerability, Safety and Pharmacokinetics of AST-201 in Patients With GPC3-positive Advanced Solid Tumors
Run by Aptamer Sciences, Inc. · NCT06687941 · Data updated 2026-11-12
This study is testing a new treatment called AST-201 to see if it can help people with advanced solid tumors that have a specific marker called GPC3.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 19 and older with GPC3-positive advanced recurrent solid tumors.
✕Probably not a fit
Patients with ischemic heart disease or those who have received anti-tumor treatment within the last four weeks may not benefit from this study.

What this trial studies
This clinical study is the first in humans to evaluate AST-201, a novel aptamer-drug conjugate, in patients with GPC3-positive advanced solid tumors. The study is divided into two phases: Phase 1a focuses on determining the maximum tolerated dose and pharmacokinetic properties of AST-201, while Phase 1b assesses its safety and preliminary efficacy across specific tumor types. Patients will receive AST-201 as a single agent, and the study aims to gather data to support future clinical development of this treatment for GPC3-positive tumors.
Why it matters
Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced solid tumors that express GPC3.
How similar studies have gone: While this approach is novel, preclinical studies have shown promising efficacy of AST-201 in GPC3-positive tumor models.
