Brief Title
Anti-ALPP CAR-T Cells Immunotherapy for Ovarian and Endometrial Cancer
Official Title
A Single-Arm, Single-Center, Open-Label Pilot Study of Anti-ALPP CART-cells in Patient With Alkaline Phosphatase, Placental (ALPP)-Positive Metastatic Ovarian and Endometrial Cancer.
Brief Summary
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
metastatic ovarian and endometrial cancer.
Detailed Description
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
Study Phase
Phase 1/Phase 2
Study Type
