Recruiting PHASE1 Acute Lymphoid Leukemia

New treatment option for Acute Lymphoid Leukemia

Official title UCD19 CAR T Therapy in Adults With B-ALL and MRD Positivity in CR1

ClinicalTrials.gov ID: NCT05535855

What this study is testing

What is CD19 Directed CAR T Cell?

CD19 Directed CAR T Cell is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for acute lymphoid leukemia.

Also referred to as UCD19 CAR T cells.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
This open-label, single arm Phase 1/1b trial aims to determine the safety and tolerability of anti-CD19 chimeric antigen receptor-expressing (CAR) T cells (UCD19 CAR T) in adults with B-ALL that are in first complete remission with MRD positivity. This trial will enroll 10 patients during Phase 1 for apheresis, treatment with lymphodepleting chemotherapy, and UCD19 CAR T cell infusion.
