Baclofen-Amitriptyline Hydrochloride-Ketamine Gel in Treating Peripheral Neuropathy Caused by Chemotherapy in Patients With Cancer
The Use of Topical Baclofen, Amitriptyline HCI, and Ketamine (BAK) in a PLO Gel vs. Placebo for the Treatment of Chemotherapy Induced Peripheral Neuropathy: A Phase III Randomized Double-Blind Placebo Controlled Study

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.

OBJECTIVES:

Primary

  • Compare the effectiveness of baclofen-amitriptyline hydrochloride-ketamine (BAK) gel versus placebo, in terms of improving sensory neuropathy, in cancer patients with chemotherapy-induced peripheral neuropathy.

Secondary

  • Compare motor and autonomic symptoms and functioning, mood states, pain, and peripheral neuropathy in these patients.
  • Assess the adverse event profile of topical BAK gel.
  • Explore whether topical BAK gel is absorbed systemically.

OUTLINE: Patients are stratified according to neurotoxic chemotherapy (active vs non-active), current use of opioids or oral pain medications (yes vs no), pain rating (4-7 vs 8-10), and prior ineffective pharmacologic treatment for peripheral neuropathy (yes vs no). Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients apply 1 spoonful of baclofen-amitriptyline hydrochloride-ketamine gel topically to each area of pain, numbness, and/or tingling on the feet and/or hands twice daily for 4 weeks.
  • Arm II: Patients apply 1 spoonful of placebo gel topically to each area of pain, numbness, and/or tingling on the feet and/or hands twice daily for 4 weeks.

Some patients in both arms may choose to continue on the active gel or, if on placebo, begin the active gel for an additional 8 weeks off study.

Patients complete health, pain, mood, and quality of life questionnaires at baseline and periodically during study. Patients also record adverse symptoms weekly in a Symptom Experience Diary.

  • Placebo Comparator: Arm II
    Patients apply 1 spoonful of placebo gel topically to each area of pain, numbness, and/or tingling on the feet and/or hands twice daily for 4 weeks.

PRIOR CONCURRENT THERAPY:

  • See Disease Characteristics
  • More than 30 days since prior anticonvulsants, tricyclic antidepressants, monoamine oxidase inhibitor, or other neuropathic pain medication (e.g., carbamazepine, phenytoin, valproic acid, gabapentin, lamotrigine, topical lidocaine patch or gel, capsaicin cream, or amifostine)

    • Patients treated with any of these agents for peripheral neuropathy for ≤ 1 week during the past 30 days are eligible provided they are no longer taking the agent
  • More than 5 years since prior percutaneous transluminal coronary angioplasty or coronary artery bypass graft
