PTC THERAPEUTICS, INC. SHAREHOLDER REMINDER: Kessler Topaz Meltzer & Check, LLP Reminds PTC Therapeutics, Inc. Shareholders of Class Action Lawsuit — PTCT

RADNOR, PA / ACCESSWIRE / April 4, 2016 / The law firm of Kessler Topaz Meltzer & Check, LLP reminds PTC Therapeutics, Inc. (Nasdaq: PTCT) (“PTC” or the “Company”) shareholders that a class action lawsuit has been filed on behalf of purchasers of the Company’s securities between May 6, 2014 and February 29, 2016, inclusive (the “Class Period”).

PTC shareholders who purchased their securities during the Class Period may, no later than May 2, 2016, petition the Court to be appointed as a lead plaintiff representative of the class. For additional information about this lawsuit, or to request information about the action online, please visit https://www.ktmc.com/new-cases/ptc-therapeutics-inc#join.

PTC is a biopharmaceutical company focused on the discovery, development and commercialization of orally administered, small molecule therapeutics targeting an area of ribonucleic acid (“RNA”) biology, known as post-transcriptional control.

The shareholder class action complaint alleges that PTC and certain of its executive officers made a series of false and misleading statements, and failed to disclose material adverse facts, about the Company’s new drug application (“NDA”) for its lead product candidate, Translarna.

On February 23, 2016, PTC disclosed that it had received a “Refuse to File Letter” from the FDA regarding the Company’s NDA for Translarna as “the application was not sufficiently complete to permit a substantive review.” On this news, shares of PTC’s stock declined $17.42 per share, or over 61%, to close on February 23, 2016 at $10.84 per share.

On February 29, 2016, PTC provided additional details about the FDA’s Refusal to File Letter, and disclosed that: (1) “in the view of the FDA, both the Phase 2b and ACT DMD trials were negative and do not provide substantial evidence of effectiveness;” (2) the FDA “characterized certain of the company’s adjustments to the ACT DMD study as post hoc and therefore not supportive of effectiveness;” and (3) “the FDA noted that the NDA did not contain adequate information regarding the abuse potential of Translarna, a requirement for new molecules that cross the blood-brain barrier.” On this news, shares of PTC’s stock declined an additional $2.43 per share, or over 30%, to close on March 1, 2016 at $5.55 per share.

PTC shareholders who purchased their securities during the Class Period (May 6, 2014 – February 29, 2016) may, no later than May 2, 2016, petition the Court to be appointed as a lead plaintiff representative of the class.
