A double-blind, placebo-controlled trial of a topical treatment for chemotherapy-induced peripheral neuropathy: NCCTG trial N06CA.
Summary
RATIONALE: Baclofen-amitriptyline-ketamine (BAK) gel may lessen peripheral neuropathy caused by chemotherapy. It is not yet known whether BAK gel is more effective than a placebo in treating peripheral neuropathy caused by chemotherapy .
PURPOSE: This randomized phase III trial is studying BAK gel to see how well it works compared with a placebo in treating peripheral neuropathy caused by chemotherapy in patients with cancer.
