Anti-ALPP CAR-T Cells Immunotherapy for Advanced Solid Tumors

A Single-Arm, Single-Center, Open-Label Pilot Study of Anti-ALPP CART-cells in Patient With Alkaline Phosphatase, Placental (ALPP)-Positive Advanced Solid Tumor

The goal of this clinical trial is to evaluate the safety and efficacy of anti-ALPP chimeric antigen receptor (CAR)-modified T (CAR-T) cells in treating patients with ALPP-positive Advanced Solid Tumors.

Primary Objectives:

To evaluate the number of ALPP-positive participants with treatment-related adverse events as assessed by CTCAE v4.0 after infusion with anti-ALPP CAR-T cells.

Secondary Objectives:

The number of patients experience objective response from anti-ALPP CAR-T cells treatment

To evaluate the progression-free survival (PFS) of anti-ALPP CAR-T cells in patients with ALPP-positive patients.

The number and percent of ALPP-CART cells in peripheral blood from ALPP-positive patients at 6 months after infusion
