Theratechnologies Inc.: FDA Approves Alternative Storage Conditions for EGRIFTA(TM)

Theratechnologies Inc. (TSX:TH) (NASDAQ:THER) announced today that the U.S. Food and Drug Administration (FDA) has granted approval of a Supplemental New Drug Application (sNDA), filed by its commercial partner, EMD Serono, Inc., providing for the revision of the EGRIFTA(TM) (tesamorelin for injection) prescribing information, to include storage conditions for the 2 mg vial up to 12 weeks at or below 25 degrees C after dispensing to the patient. Previously, EGRIFTA(TM) could only be stored between 2 degrees C and 8 degrees C (36 degrees F and 46 degrees F) until the expiration date.

"Bringing incremental improvements to EGRIFTA(TM)'s presentation and formulation continues to be a top priority for Theratechnologies. Being able to store EGRIFTA(TM) at temperatures reaching 25 degrees C provides storage flexibility for patients who don't always have access to a refrigerator. Other potential improvements are part of our product lifecycle management strategy aimed at improving the product," stated Luc Tanguay, President and CEO of Theratechnologies.

In September 2012, EGRIFTA(TM) became available as a single-vial presentation.
