Arms Assigned Interventions
Experimental: Arm I
Patients receive oral L-carnitine L-tartrate twice daily beginning on day 2 of the first course of chemotherapy and continuing until after completion of 4 courses of chemotherapy.
Drug: L-carnitine L-tartrate
Given orally
Placebo Comparator: Arm II
Patients receive oral placebo twice daily beginning on day 2 of the first course of chemotherapy and continuing until after completion of 4 courses of chemotherapy.
Other: placebo
Given orally

Detailed Description:

OBJECTIVES:

  • To evaluate the tolerability and usefulness of the dietary supplement, L-carnitine L-tartrate, in the prevention of chemotherapy-induced peripheral neuropathy in women with metastatic breast cancer.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive oral L-carnitine L-tartrate twice daily beginning on day 2 of the first course of chemotherapy and continuing until after completion of 4 courses of chemotherapy.
  • Arm II: Patients receive oral placebo twice daily beginning on day 2 of the first course of chemotherapy and continuing until after completion of 4 courses of chemotherapy.

Patients complete questionnaires periodically to assess neuropathy, pain, fatigue, sleep, and activities of daily living.

After completion of study treatment, patients are followed at 4 weeks and then every 3 months thereafter.
