Mechanisms of Bortezomib-induced Peripheral Neuropathy

Project: Research project

Description

DESCRIPTION (provided by applicant): Chemotherapy-induced peripheral neuropathy (CIPN) is a serious side-effect arising in ~400,000 cancer patients yearly and often limits chemotherapy dosage. Pain and other quality of life impairments caused by CIPN are increasing as many forms of cancer become chronic conditions, with an estimated annual cost of ~$2.5 billion dollars (NCI Directors Consensus Workshop, June 2011). It has been assumed that as target-specific therapies were discovered, the off-target effect of peripheral neuropathy would lessen. However, as specific mechanism-based therapies (e.g. proteasome and Jak-2 inhibitors) have been introduced, the incidence of painful, chronic neuropathy has persisted at 30-40% of treated patients. Approaches to limit the impact of CIPN include prevention and symptomatic treatment of neuropathic pain. Preventive strategies are complicated by the risk that protection from CIPN may reduce the primary cancer cell killing effect of a drug. Symptomatic treatments for pain are frequently not successful, reflecting a lack of understanding of the underpinnings of neuropathic pain. In this application, the candidate proposes a comprehensive strategy to understand the biological mechanisms of CIPN caused by a specific chemotherapeutic drug (bortezomib) and the physiologic mechanisms underlying pain caused by the drug. The studies are expected to have broader implications for other diseases of the peripheral nervous system. The candidate is an M.D./Ph.D.-trained neurologist with advanced clinical training in peripheral nerve disorders whose career goal is to perform mechanistic and translational investigations of peripheral nerve disorders and neuropathic pain. Chemotherapy-induced peripheral neuropathy will be used as the model disease system to achieve this goal. The career development plan will be mentored by Dr. Anthony Windebank, a neuromuscular physician-scientist with expertise in CIPN, and Dr. Gianrico Farrugia whose lab focuses on structure-function studies of voltage-gated ion channels. The career development plan combines the strengths of the candidate, the mentors, and the research institution in order to provide an opportunity for the candidate to become a successful independent investigator of peripheral nerve disorders.
