Inaticabtagene Autoleucel (Inati-cel; CNCT19) Treatment for MRD-Positive B-ALL Patients in CR1

Recruiting now · Phase 2

Conditions studied: Acute Lymphoblastic Leukemia

In brief

This investigator-initiated, prospective, single-arm, open-label, single-center clinical study aims to evaluate the efficacy and safety of Inaticabtagene autoleucel (Inati-cel;CNCT19)CD19 CAR-T theraphy in adults B-ALL that are in first complete remission(CR1) with minimal residual disease (MRD) positivity. This trial will enroll 20 participants for leukapheresis and treatment with lymphodepleting chemotherapy followed by Inati-cel CAR T cell infusion. Patients will be assessed for MRD negativity rate(at months 1, 2, 3, and 6 after CAR-T transfusion), duration of MRD negativity, overall survival(OS), relapse-free survival(RFS), pharmacokinetics(PK) characteristics, incidence of adverse events(AEs), exploratory biomarker research at 1,2,3,6,9,12,15,18,21 and 24- months post Inati-cel infusion.
