Summary
Brief summary (as posted)
20010133 is an open-label, dose escalation study in pediatric patients with acute leukemias receiving myelotoxic therapy (high dose etoposide, cyclophosphamide and total body irradiation \[TBI\]) followed by hematopoietic stem cell transplant (HSCT). The study will evaluate the safety and pharmacokinetics of palifermin in pediatric patients. Three doses (40 μg/kg/day, 60 μg/kg/day, and 80 μg/kg/day) are to be evaluated in each age group (1 to 2, 3 to 11, and 12 to 16 years, respectively) using a conventional dose escalation design. Palifermin is administered for 3 consecutive days (Day -10 to Day -8, respectively) before the start of the conditioning regimen and for 3 consecutive days (Day 0 to Day +2) following HSCT. Patients will be enrolled simultaneously to each age group to identify a safe, well tolerated, efficacious dose in each age group. Patients will also be followed for secondary malignancies, progression-free survival (PFS) and overall survival (OS)

- Palifermin Dose Escalation
- description
- A 3 dose escalation design. Sucessive cohorts of patient (9 patients per group) will each be administered Palifermin as an IV bolus injection (40, 60 or 80 µg) once daily for 3 consecutive days before the start of conditioning regimen (chemotherapy and total body irradiation) and after HCST (Day -10, -9, -8 and Day 0, +1, +2 respectively).

Primary outcomes (1)
- measure
- Incidence of Dose Limiting Toxicities (DLTs)
- timeFrame
- Approximately 1 month duration (Day -10 through Day +16)
- description
- A DLT is appearance of side effects during treatment severe enough to prevent further increase in dosage or strength of treatment agent, or to prevent continuation of treatment at any dosage level. A DLT was defined as: Grade 3 or 4 AE \[based on Cancer Therapy Evaluation Program Common Terminology Criteria for Adverse Events (CTCAE) v3.0\] considered by the investigator to be related to palifermin with the exceptions: Grade 3 erythema, pruritus or rash that resolves within 7 days of the last dose of palifermin. The percentage of particiapnts with a DLT during the study was assessed.
