Primary Outcome Measures:
  • Improvement of neuropathy scores from baseline to the completion of 2 cycles will be analyzed.The same measurement after 4 cycles also will be analyzed & will be reported. [ Time Frame: 4 weeks ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 450
Study Start Date: July 2006
Estimated Study Completion Date: October 2014
Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: MV alone
Multivitamin only
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.
Experimental: MV+B6+B12
Multivitamin, plus B6 tablets and B12 injections
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

Detailed Description:

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.
