Clinical trials

This is a Phase I, first-in-human, open-label study of CRPA1A2, a bispecific T-cell engager, in participants with HLA-A\*02:01-positive and MAGE-A1-positive advanced solid tumors. The study is designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary anti-tumor activity of CRPA1A2, and to identify recommended dose(s) for further evaluation. The study consists of 2 parts: a dose escalation part (Part A) and a dose optimization part (Part B). In Part A, participants will receive escalating doses of CRPA1A2 to determine the recommended dose(s) for optimization, with additional backfill cohorts permitted. In Part B, 2 to 3 selected recommended dose(s) will be further evaluated in participants with selected tumor types to better characterize safety and preliminary anti-tumor activity. CRPA1A2 will be administered by intravenous infusion in 28-day cycles, starting at 0.0003 mg/kg. Weekly dosing is planned, although alternative dosing schedules may be explored based on emerging data. Treatment will continue until disease progression, intolerable toxicity, initiation of new anti-tumor therapy, other discontinuation criteria are met, or study termination.

A single center, open, single arm dose escalation and dose expansion phase I study to evaluate the safety, tolerability, and efficacy of CRTE7A2-01 TCR-T cells in HLA-A\*02:01+ Subjects HPV16 positive advanced cervical, anal, or head and neck cancers. The study will determine RP2D of CRTE7A2-01 TCR-T cell injection.
