Study 22001, "A Double-Blind, Placebo-Controlled, Flexible-Dose Evaluation of the Efficacy, Safety, and Tolerability of STX209 in the Treatment of Irritability in Subjects with Fragile X Syndrome" currently is evaluating the efficacy of STX209 (R-baclofen) for management of typical problem behaviors, such as irritability and aggression, in subjects with FXS.
