Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

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.
