Last updated: October 8, 2024
Sponsor: Kara Yakhteh Tajhiz Azma Company
Overall Status: Active - Recruiting

Phase

1/2

Condition

Leukemia

Treatment

anti-CD19 CAR T cell therapy

Clinical Study ID

NCT06635330
IR.NREC.1403.003
  • Ages 2-18
  • All Genders

Study Summary

The goal of this clinical trial is to evaluate the safety and efficacy of CD19 CAR-T cells in pediatric patients of all genders, aged 2 to 18 years, with relapsing or refractory B cell acute lymphoblastic leukemia (r/r B-ALL). The main questions it aims to answer are as following:

  1. What is the percentage of patients with overall remission rate (ORR) of complete response (CR) or complete remission with incomplete blood count recovery (CRi)?

  2. What is the rate of Event-free survival at first month and 2-3 months after intervention?

  3. What is the rate of Overall survival at first month and at 3 months after the intervention?

Study Description

B-cell acute lymphoblastic leukemia (B-ALL), as the most common type of pediatric tumor, is identified by unregulated cell proliferation of immature lymphoid cells that can infiltrate the bone marrow and blood. Also, relapse and refractory B-ALL (R/R B-ALL) is the main reason of global mortality due to the constraints of combination chemotherapy.

Over the past few years, substantial advancements have been made in treatment of ALL, specifically in the R/R context. Chimeric antigen receptor T (CAR-T) cells are a type of cancer immunotherapy treatment that function through modification of patient T cells to express CAR antigen on their surface. CAR-T cells aimed at CD19 have demonstrated promising activity in treatment of r/r B-ALL. In this study we aim to evaluate safety and efficacy of Anti-CD19 CAR T cell therapy in children with R/R B-ALL.
