Anavex Life Sciences Corp. reported top-line data from the 33-subject phase III study with Anavex 2-73 (blarcamesine) in adult females with Rett syndrome, turning up a statistically significant improvement over placebo for the primary efficacy endpoint as well as for all the secondary efficacy endpoints. The sigma-1 receptor activator, given as a once-daily, oral liquid, proved well-tolerated, too, with good compliance by patients, Anavex said.
