Janney Capital analyst Ken Trbovich notes that Sunovion Pharmaceuticals, a wholly owned U.S.-based subsidiary of Sumitomo Dainippon Pharma, reported positive top-line results from its Phase 3 trial of APL-130277 for treating OFF-rescue in Parkinson's Disease patients. While the respective Phase 3 studies were not head-to-head, it would appear APL-130277 may be the more potent OFF rescue treatment, with the trade-off being higher rates unpleasant side effects such as nausea and dizziness, the analyst notes. Trbovich believes this could take some of the luster off perceived M&A value of Acorda Therapeutics, but it is unlikely to eliminate interest. He reiterates a Neutral rating on Acorda Therapeutics' shares.
