** SAREPTA THERAPEUTICS INC, $26.4401, +32.33 pct
The company said data from an extended study of its drug to treat a rare muscular disorder in young boys showed continued stabilization of walking ability in patients.

In October 2012, Sarepta said the trial met its main goal of increasing the level of a key protein after 48 weeks of treatment. The study was extended to monitor the drug's safety and efficacy.
