A Randomized Phase III Study of Vitamins B6 and B12 to Prevent Chemotherapy-Induced Neuropathy in Cancer Patients
A Randomized Phase III Study of Vitamins B6 and B12 to Prevent Chemotherapy-Induced Neuropathy in Cancer Patients.

Primary Objective:To determine the efficacy of the combination of vitamin B6 and B12 in preventing chemotherapy induced neuropathy

Neuropathy can be a significant side effect of chemotherapy using platinum compounds, taxanes, and vinca alkaloids. There is clinical and preclinical data that vitamin B6 and B12 may alleviate neuropathy in experimentally induced neuropathy in animal models, or clinical neuropathy such as diabetic neuropathy. This is a randomized phase III study of the use of multivitamins with or without vitamin B6 and B12 to prevent or relieve neuropathic toxicity from chemotherapy in patients receiving chemotherapy. Patients will be stratified by type of chemotherapy agent (3 groups), presence or absence of neuropathy at baseline, and randomized to receive placebo or vitamin b6/b12 supplementation.

  • Dietary Supplement: Multivitamin
    Multivitamins containing no more than 10 mg of pyridoxine and/or 10 micrograms of Vitamin B12 will be given to the patients on this arm.
  • Dietary Supplement: Vitamin B12, Vitamin B6

    On the first day of chemotherapy, start

    1. pyridoxine 50 mg tid orally and continue for no more than 30 days past the cumulative chemotherapy dose (until the next cycle starts)
    2. Vitamin B12 one mg. i.m., q 3 or 4 weeks, depending on the timing of the chemotherapy for 4 doses.Cumulative doses(in mg/m2) are: paclitaxel-700;docetaxel-300;vincristine-16;navelbine-480;cisplatin-300;oxaliplatin-400
  • Active Comparator: MV alone
    Multivitamin only
    Intervention: Dietary Supplement: Multivitamin
  • Experimental: MV+B6+B12
    Multivitamin, plus B6 tablets and B12 injections
