ViroPharma is set to initiate VP20629 Phase II trial in the second half of 2013

ViroPharma: Strengthening Financial Profile & Pipeline Indicate Long-Term Upside, Ivan Deryugin, December 27, 2012

VP20629 is licensed from Intellect Neurosciences for the treatment of Friedreich’s Ataxia (FA), a rare neurodegenerative disease that affects about 1 in 50,000 people. Symptoms of FA include heart disease, speech problems, and gait disturbance. It is estimated that there are 6,000 FA patients here in the United States. Phase I data for VP20629 showed that the drug was well-tolerated at all dose levels, and ViroPharma is set to initiate a Phase II trial in the second half of 2013, and the company plans to file for orphan drug status once Phase II data is available
