Purpose
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)

Primary Outcome Measures:
- Incidence of Dose Limiting Toxicities (DLTs) [ Time Frame: Approximately 1 month duration (Day -10 through Day +16) ] [ Designated as safety issue: Yes ]
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.
Secondary Outcome Measures:
- Incidence of Serum Palifermin Antibody Formation [ Time Frame: Approximately 4 month duration (Through Day + 100 (+/- 40 days)) ] [ Designated as safety issue: Yes ]The percentage of participants developing palifermin antibodies during the study was assessed.
- Incidence of Severe Adverse Events (AEs) [ Time Frame: Approximately 1 1/2 months duration (Through Day +30/End of Treatment) ] [ Designated as safety issue: Yes ]The percentage of participants with a severe AE during the study was assessed.
- Incidence of Laboratory Abnormalities [ Time Frame: Approximately 1 1/2 months duration (Through Day +30/End of Treatment) ] [ Designated as safety issue: Yes ]The percentage of participants with a laboratory value outside the normal ranges during the study.
- Pharmacokinetics of Palifermin, Clearence (CL) After the 1st Intravenous (IV) Bolus Injection for Multiple Dose Levels [ Time Frame: Day -10 ] [ Designated as safety issue: No ]Clearence was estimated as dose divided by the area under serum concentration-time curve from time zero to infinity where the dose was given in amount palifermin actually administered.
- Pharmacokinetics of Palifermin, Volume of Distribution at Steady State (Vss) After the 1st IV Bolus Injection for Multiple Dose Levels [ Time Frame: Day -10 ] [ Designated as safety issue: No ]
- Pharmacokinetics of Palifermin, Terminal Half-life (t½,z) After the 1st IV Bolus Injection for Multiple Dose Levels [ Time Frame: Day -10 ] [ Designated as safety issue: No ]The terminal half-life was calculated as ln(2)/lambda,z where lambda,z was estimated using at least three quantifiable serum concentrations of the terminal log-linear phase.
- Pharmacokinetics of Palifermin, t½,z After the 3rd IV Bolus Injection for Multiple Dose Levels [ Time Frame: Day -8 ] [ Designated as safety issue: No ]The terminal half-life was calculated as ln(2)/lambda,z where lambda,z was estimated using at least three quantifiable serum concentrations of the terminal log-linear phase.
- Pharmacokinetics of Palifermin, Area Under the Concentration Time Curve From Zero to the End of the Dosing Interval (AUCtau) After the 1st IV Bolus Injection for Multiple Dose Levels [ Time Frame: Day -10 ] [ Designated as safety issue: No ]
The AUC was estimated using the linear/log trapezoidal method for AUC0-tau from time zero to the end of the dosing interval (24 hours (hrs) post-dose)
Data collected at time points: 0, 2 minutes (min), 15 min, 30 min, 60 min, 2 hrs, 4 hrs, 6, hrs, 10, hrs and 24 hrs post-dose.
- Pharmacokinetics of Palifermin, AUCtau After the 3rd IV Bolus Injection for Multiple Dose Levels [ Time Frame: Day -8 ] [ Designated as safety issue: No ]
The AUC was estimated using the linear/log trapezoidal method for AUC0-tau from time zero to the end of the dosing interval (24 hours (hrs) post-dose)
Data collected at time points: 0, 2 minutes (min), 15 min, 30 min, 60 min, 2 hrs, 4 hrs, 6, hrs, 10, hrs and 24 hrs post-dose.
- Long-Term Follow-Up: Incidence of Secondary Malignancies [ Time Frame: Up to 4 years duration (Assessments performed on months 6, 9, 12 (+/- 30 Days) for the first year and then annually) ] [ Designated as safety issue: Yes ]
- Long-Term Follow-Up: Progression Free Survival [ Time Frame: Up to 4 years duration (Assessments performed on months 6, 9, 12 (+/- 30 Days) for the first year and then annually) ] [ Designated as safety issue: Yes ]Progression free survival (PFS) was defined as the number of days between the date of first investigational product administration and the date when physical or radiological evidence of disease progression is determined or death (regardless of cause)
- Long-Term Follow-Up: Overall Survival [ Time Frame: Up to 4 years duration (Assessments performed on months 6, 9, 12 (+/- 30 Days) for the first year and then annually) ] [ Designated as safety issue: Yes ]Overall survival was defined as the number of days from the date of first investigational product administration to the date of death (regardless of cause)
