Phase 3: testing Fludarabine for B-cell Acute Lymphoblastic Leukemia

The researchers are doing this study to find out whether PK-targeted fludarabine is an effective Lymphodepletion (LD) chemotherapy approach for people with relapsed/refractory B-cell acute lymphoblastic leukemia (B-ALL) who will receive tisagenlecleucel CAR T-cell therapy. The researchers will compare PK-targeted fludarabine dosing with standard fludarabine dosing to see which treatment approach is more effective.

Official registry: https://clinicaltrials.gov/study/NCT07223021 · Memorial Sloan Kettering Cancer Center · enrollment listed as 130

What this phase means

Phase 3: this treatment already looked useful in smaller studies. Now it is tested in a large group, often against standard care or a dummy treatment, to see if it should be approved.

Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.

What the registry says happens

If you join, the listed intervention(s) are Fludarabine, Cyclophosphamide, or Fludarabine. The registry lists allocation as randomized. The researchers are doing this study to find out whether PK-targeted fludarabine is an effective Lymphodepletion (LD) chemotherapy approach for people with relapsed/refractory B-cell acute lymphoblastic leukemia (B-ALL) who will receive tisagenlecleucel CAR T-cell therapy.

They plan to enroll about 130 people at 8 sites. Taking part typically means taking a study drug (or dummy pill), an infusion or injection of a biologic plus check-ins.

Primary outcome (registry wording): compare the event free survival (EFS )

Who it is for (from inclusion criteria)

  • Ages 1 Year to any
  • Patients with B-ALL and eligible to receive commercial tisagenlecleucel
  • Patient's weight \> 9 kg at time of lymphodepleting chemotherapy
  • Adequate organ function at time of LD is required and is defined:
  • Hepatic: Serum bilirubin ≤ 2 mg/dL, unless benign congenital hyperbilirubinemia
  • Hepatic: AST and ALT \< 5x the upper limit of normal for age, unless thought to be leukemic disease-related
  • Renal: Calculated glomerular filtration rate (GFR) ≥ 70 ml/min/1.73m\^2. (based on Schwartz formula GFR (mL/min/1.73 m²) = (36.2 × Height in cm) / Creatinine in mg/dL
