PTC Therapeutics, Inc. provided revenue guidance for the fiscal year ending December 31, 2017. For the period, the company expects to achieve ex-U.S. Translarna nmDMD net sales of between $105 and $125 million, assuming current exchange rates, representing continued strong growth year-over-year of its sustainable DMD business. This is driven by both increased penetration into the over 25 countries where Translarna is currently available as well as continued geographic expansion into new territories.
