SECONDARY OBJECTIVES:

I. Other measures of neuropathy as measured by the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ) CIPN20 motor subscale, the EORTC QLQ CIPN20 autonomic scale, and the total Common Terminology Criteria for Adverse Events (CTCAE) neuropathy scale.

II. Adverse event profiles will also be assessed using symptom questionnaires and CTC...
