Chemotherapy Induced Peripheral Neuropathy Natural History Study (EPIPHANY)

Study Overview
=================
Brief Summary
-----------------
This is a prospective natural history study of CIPN in approximately 200 participants receiving taxanes (paclitaxel, docetaxel) for breast cancer, bortezomib for multiple myeloma, oxaliplatin-based regimens for colorectal cancer, or vincristine for lymphoma.. Demographic data, medical history, electronic PROs, ClinROs blood biomarkers including NF-L, PGx DNA analyses and Bedside-QST will be assessed at Baseline. The Observation Period will initiate with the first dose of chemotherapy and conclude with the last dose of chemotherapy. During the Observation Period, participants will be evaluated for the development of CIPN using PROs and ClinROs. Blood biomarkers and Bedside-QST will be measured at various timepoints corresponding with treatment regimen schedules throughout the observation period. The Post Chemotherapy Follow-up Period will begin with the first visit after the last dose of chemotherapy and conclude 6 months after the last dose of chemotherapy. During the Post Chemotherapy Follow-up Period, participants will be evaluated for CIPN using PROs and ClinROs. Blood biomarkers and Bedside-QST will also be measured at the beginning and at the end of the Post-Chemotherapy Follow-up Period. PROs will be assessed electronically on a monthly basis.
