Study Description

Brief Summary:
Many types of chemotherapy may cause nerve damage as a side effect. This neurotoxicity can manifest as peripheral sensory neuropathy (characterized by numbness, tingling, or pain). The goal of this study is to determine the efficacy of the combination of vitamin B6 and B12 in preventing chemotherapy induced neuropathy.

Condition or disease Intervention/treatment Phase
Cancer Dietary Supplement: Multivitamin (MV) Dietary Supplement: Multivitamin + Vitamin B12 + Vitamin B6 Drug: Chemotherapy Phase 3

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.

Arm Intervention/treatment
Active Comparator: Multivitamin (MV)
1 multivitamin pill will be taken orally, daily starting on the first day of chemotherapy and continuing for no more than 30 days past the cumulative chemotherapy dose (until the next cycle starts)
 Dietary Supplement: Multivitamin (MV)
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.

Drug: Chemotherapy

Patients are treated per standard of care according to the choice of the treating physician with heavy metals (cisplatin, oxaliplatin), taxanes (paclitaxel, docetaxel), or vinca alkaloids (vincristine, vinorelbine)

Ranges of cumulative doses (in mg/m2) are:

paclitaxel, 700-960; docetaxel, 240-400; vincristine, 8-16; vinorelbine, 360-480; cisplatin, 240-400; oxaliplatin, 400-800; abraxane, 1200-1800

  • Vinorelbine tartrate (Navelbine)
Experimental: Multivitamin + Vitamin B12 + Vitamin B6

1 multivitamin pill will be taken orally, daily starting on the first day of chemotherapy and continuing for no more than 30 days past the cumulative chemotherapy dose (until the next cycle starts).

The patient will also take the following, starting on the first day of chemotherapy:

  1. pyridoxine 50 mg three times per day, orally and continue for no more than 30 days past the cumulative chemotherapy dose (until the next cycle starts)
  2. Vitamin B12 one mg injected intramuscularly, every 3 or 4 weeks, depending on the timing of the chemotherapy for 4 doses.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Neurotoxicity Assessment at Baseline [ Time Frame: At study start; prior to treatment (week 0) ]
    Neurotoxicity is evaluated using The Functional Assessment of Cancer Therapy-Taxane (FACT-Tax) questionnaire. FACT-Tax is a validated, self-reported instrument. The questionnaire consists of 11 questions and possible scores for each question range from 0 (no neurotoxicity symptoms) to 4 (worst possible neurotoxicity symptoms). The total score for any patient can therefore range from 0 to 44. The questionnaire is given to patients to fill out at baseline (prior to chemotherapy treatment) and the mean total score for all patients is reported.

  2. Neurotoxicity Assessment at Cycle 2 [ Time Frame: 2 weeks ]
    Neurotoxicity is evaluated using The Functional Assessment of Cancer Therapy-Taxane (FACT-Tax) questionnaire. FACT-Tax is a validated, self-reported instrument. The questionnaire consists of 11 questions and possible scores for each question range from 0 (no neurotoxicity symptoms) to 4 (worst possible neurotoxicity symptoms). The total score for any patient can therefore range from 0 to 44. The questionnaire is given to patients to complete at completion of cycle 2 of chemotherapy treatment and the mean total score for all patients is reported.

  3. Neurotoxicity Assessment at Cycle 4 [ Time Frame: 4 weeks ]
    Neurotoxicity is evaluated using The Functional Assessment of Cancer Therapy-Taxane (FACT-Tax) questionnaire. FACT-Tax is a validated, self-reported instrument. The questionnaire consists of 16 questions and possible scores for each question range from 0 (no neurotoxicity symptoms) to 4 (worst possible neurotoxicity symptoms). The total score for any patient can therefore range from 0 to 44. The questionnaire is given to patients to fill out at completion of cycle 4 of their chemotherapy treatment and the mean total score for all patients is reported.

  4. Change in Neurotoxicity Assessment Between Cycle 4 and Baseline [ Time Frame: 4 weeks ]
    Neurotoxicity is evaluated using The Functional Assessment of Cancer Therapy-Taxane (FACT-Tax) questionnaire. FACT-Tax is a validated, self-reported instrument. The questionnaire consists of 11 questions and possible scores for each question range from 0 (no neurotoxicity symptoms) to 4 (worst possible neurotoxicity symptoms). The total score for any patient can therefore range from 0 to 44. The questionnaire is given to patients to fill out at baseline, cycle 2, and cycle 4 of their chemotherapy treatment. Change in neurotoxicity scores from baseline to the completion of 4 cycles are reported as the mean total score for all patients.
