Recruiting EARLY_PHASE1 Relapsed Acute Lymphoblastic Leukemia (ALL)

New treatment option for Relapsed Acute Lymphoblastic Leukemia (ALL)

Official title CAR-T Cell Therapy for ALL

ClinicalTrials.gov ID: NCT07695012

What this study is testing

What is CAR-T cell infusion?

CAR-T cell infusion is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for relapsed acute lymphoblastic leukemia (all).

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
Acute lymphoblastic leukemia (ALL) is the most common malignancy in children and the second most frequent acute leukemia in adults. B-cell ALL constitutes approximately 85% of all ALL diagnoses.
  • Phase 1: an early, usually small safety study
