Phase II Trial Of Subcutaneous Amifostine For Reversal Of Persistent Paclitaxel-Induced Peripheral Neuropathy
Phase II Trial Of Subcutaneous Amifostine For Reversal Of Persistent Paclitaxel-Induced Peripheral Neuropathy
RATIONALE: Amifostine may be effective in reducing pain, numbness, tingling, and other symptoms of peripheral neuropathy.
PURPOSE: This phase II trial is studying how well amifostine works in reducing pain, numbness, tingling, and other symptoms of peripheral neuropathy in patients who have received paclitaxel for solid tumors.
OBJECTIVES:
Primary
Secondary
OUTLINE: This is an open-label, multicenter study.
Patients receive amifostine subcutaneously three times weekly for 4 weeks in the absence of symptom progression or unacceptable toxicity. Patients achieving a complete or partial response receive an additional 4 weeks of therapy.
Neuropathy symptoms are assessed using the FACT-GOG-NTX questionnaire administered at baseline, weekly during therapy, and at 12 weeks and the Weinstein Enhanced Sensory Test administered at baseline and at 4, 8, and 12 weeks.
Patients are followed at 12 weeks.
PROJECTED ACCRUAL: A total of 20-40 patients will be accrued for this study within 10-20 months.
