Topiramate as a Disease Altering Therapy for Cryptogenic Sensory Peripheral Neuropathy

NeuroNEXT [1] and the National Institute of Neurological Disorders and Stroke (NINDS) [2] are undergoing a double-blind, placebo clinical trial looking at the effectiveness of treating peripheral neuropathy [3] with the FDA-approved drug, topiramate [4]. This is a 96-week placebo-controlled trial of topiramate at a target dose of 100 mg daily (50 mg twice daily) as a potentially disease altering therapy for Cryptogenic Sensory Peripheral Neuropathy (CSPN).

What is Cryptogenic Sensory Peripheral Neuropathy?

A common cause of neuropathy is diabetes, but in about 25 to 50% of the population, no cause is found.  This group is often referred to as Cryptogenic Sensory Peripheral Neuropathy. Symptoms of CSPN typically progress slowly. On examination, there may be additional mild toe flexion and extension weakness. Electrophysiologic testing and histology reveals axonal neuropathy. Prognosis is usually favorable, as most patients maintain independent ambulation. Besides patient education and reassurance, management is focused on pharmacotherapy for neuropathic pain and physical therapy for balance training, and, occasionally, assistive devices.
