Early Phase 1
Recruiting
Conditions
Relapsed/Refractory Acute Myeloid Leukemia
Interventions
Biological: gdT cell injection targeting B7-H3 chimeric antigen receptor
Registration Number
NCT05722171
Lead Sponsor
PersonGen BioTherapeutics (Suzhou) Co., Ltd.
Brief Summary

This is a single-arm, open-label, dose-escalation study to explore the safety, efficacy, and cytodynamic characteristics of the drug, and to initially observe the efficacy of the drug in subjects with relapsed/refractory B7-H3-positive acute myeloid cell line leukemia.

Detailed Description

Eligible subjects will receive 1.0×10\^8 CAR gdT, 2.0×10\^8 CAR gdT, 4.0×10\^8 CAR gdT, or additional doses may be added at the discretion of investigator and sponsor.
