Official title

A Pilot, Randomized, Double-blind, Placebo-controlled Phase I Study to Determine the Safety and Tolerability of Varenicline (Chantix®) in Treating Spinocerebellar Ataxia Type 3

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Spinocerebellar ataxia (SCA) is a group of inherited disorders characterized by cerebellar degeneration leading to imbalance, incoordination, speech difficulties and problems with walking. Recently, individual case reports have suggested that varenicline, a drug used in smoking cessation, produces substantial improvement in patients with several inherited ataxias. A modest response was noted in 5 patients with SCA, suggesting that it is potentially efficacious in this disorder as well. Although this agent is available for off-label use, the severe side effects noted with its use and the lack of long-term toxicity data demand that it be systematically assessed. The present study will test whether varenicline is safe and potentially efficacious in a heterogeneous cohort of adults with SCA.
