Clinical Trial Summary

RATIONALE: Topical cream containing amitriptyline and ketamine may help relieve pain, numbness, tingling, and other symptoms of peripheral neuropathy. It is not yet known whether topical amitriptyline and ketamine cream is more effective than a placebo in treating peripheral neuropathy caused by chemotherapy.

PURPOSE: This randomized phase III trial is studying the side effects and how well topical amitriptyline and ketamine cream work compared with a placebo in treating peripheral neuropathy caused by chemotherapy in patients with cancer.


Clinical Trial Description

OBJECTIVES:

- Compare the analgesic properties and safety of topical amitriptyline and ketamine hydrochloride cream vs placebo in cancer patients with chemotherapy peripheral neuropathy (CPN) who have received taxanes or other cancer chemotherapy agents.

OUTLINE: This is a multicenter, double-blind, randomized, placebo-controlled study. Patients are stratified according to Community Clinical Oncology Program (CCOP) site. Patients are randomized to 1 of 2 treatment arms.

- Arm I: Patients apply amitriptyline and ketamine hydrochloride topical analgesic cream twice daily to areas of pain, numbness, or tingling in the hands and/or feet.

- Arm II: Patients apply a placebo cream twice daily to areas of pain, numbness, or tingling in the hands and/or feet.

In both arms, treatment continues for 6 weeks in the absence of disease progression or unacceptable toxicity. Patients may continue treatment for up to a total of 12 weeks.

Patients complete a peripheral neuropathy intensity and quality of sleep diary daily. Patients also complete the European Organization for Research and Treatment of Cancer Quality of Life-Chemotherapy-Induced Peripheral Neuropathy (EORTC-CIPN20) to assess change in sensory score and the Brief Pain Inventory and Hospital Anxiety and Depression Scale to assess health-related quality of life in week 3 and 6. The Vulnerable Elders Survey (VES-13) is administered at baseline to assess level of physical activity and the University of Rochester Cancer Center (URCC) symptom inventory is administered to track other potentially important symptoms. The Patient Global Impression of Change Questionnaire is administered in week 6 to assess the patient's overall assessment of change since beginning treatment, including changes in pain, side effects, functional status, and overall satisfaction with treatment.

PROJECTED ACCRUAL: A total of 462 patients will be accrued for this study. ;
