PEG-Interferon Alfa-2b in Treating Young Patients With Plexiform Neurofibroma
RATIONALE: PEG-interferon alfa-2b may interfere with the growth of tumor cells.
PURPOSE: This phase I trial is studying the side effects and best dose of PEG-interferon alfa-2b in treating young patients with plexiform neurofibroma.
Neoplasm of Uncertain Malignant Potential
Unspecified Childhood Solid Tumor, Protocol Specific
Biological: PEG-interferon alfa-2a
|Study Design:||Primary Purpose: Treatment|
|Official Title:||A Phase I Trial of Peginterferon Alfa-2b (PEG-Intron) for Plexiform Neurofibromas|
|Study Start Date:||September 2005|
|Study Completion Date:||January 2011|
- Determine the maximum tolerated dose of PEG-interferon alfa-2b in patients with unresectable plexiform neurofibroma. (Dose escalation portion of study closed to accrual as of 2/2005.)
- Determine the toxicity profile of this drug in these patients.
- Obtain, preliminary, information about the efficacy of this drug in these patients.
- Evaluate the growth rate of plexiform neurofibroma using volumetric MRI analysis in patients treated with this drug.
- Evaluate the impact of this drug, in terms of "worst symptom" score, in these patients.
OUTLINE: This is a dose-escalation, multicenter study. (Dose-escalation portion of the study closed to accrual as of 2/2005.)
Patients receive PEG-interferon alfa-2b subcutaneously once weekly for 2 years in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of PEG-interferon alfa-2b until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 1 of 6 patients experience dose-limiting toxicity. A total of 12 patients receive treatment at the MTD.
After completion of study treatment, patients are followed every 6 months.
PROJECTED ACCRUAL: A total of 36 patients will be accrued for this study.
