Targeted T Cell Therapy for B-Cell Acute Lymphoblastic Leukemia

Pilot Study of the Efficacy and Safety of Cluster of Differentiation Antigen 19 (CD19) /Cluster of Differentiation Antigen 22 (CD22) CART in the Treatment of Relapsed or Refractory B-Cell Acute Lymphoblastic Leukemia.

Phase1; Phase2 Interventional Shanghai Unicar-Therapy Bio-medicine Technology Co.,Ltd · NCT03614858

This study is testing a new type of immune therapy that uses specially engineered T cells to see if it can help people aged 6 to 65 with hard-to-treat B-cell acute lymphoblastic leukemia.

What this trial studies

This study evaluates the safety and efficacy of chimeric antigen receptor engineered T cell immunotherapy targeting CD19 and CD22 in patients with relapsed or refractory B-cell acute lymphoblastic leukemia. Patients aged 6 to 65 years will receive infusions of CART cells specifically designed to attack CD19 and CD22 positive leukemia cells. The study aims to enroll 20 patients and will assess their response to the treatment over time. It is an open-label, single-center study that combines both Phase 1 and Phase 2 methodologies.

Who should consider this trial

Good fit: Ideal candidates are male or female patients aged 6-65 with CD19+/CD22+ relapsed or refractory B-cell acute lymphoblastic leukemia.

Not a fit: Patients with uncontrolled infections, active hepatitis, or significant cardiovascular issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could provide a new treatment option for patients with a poor prognosis due to relapsed or refractory B-cell acute lymphoblastic leukemia.

How similar studies have performed: Other studies utilizing CAR T-cell therapies have shown promising results in treating similar conditions, indicating potential for success in this approach.
