Enhanced ALPP CAR-T treatment: Enhanced ALPP CAR-T cells Treatment follows a lymphodepletion Drug: Fludarabine and Cyclophosphamide.
Study summary
This is a single-arm, open-label, dose-escalation clinical trial designed to evaluate the safety, tolerability, expansion, and persistence of functionally enhanced ALPP-targeted engineered T Cells (Herein referred to as Enhanced ALPP CAR-T) in patients with ALPP-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.
