PTC THERAPEUTICS SHAREHOLDER ALERT:  Kessler Topaz Meltzer & Check, LLP Reminds Shareholders of Class Action Lawsuit – PTCT

RADNOR, Pa., April 12, 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”).

Investors 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 please visit https://www.ktmc.com/new-cases/ptc-therapeutics-inc#join.

PTC shareholders who wish to discuss this action and their legal options are encouraged to contact Kessler Topaz Meltzer & Check, LLP (Darren J. Check, Esq., D. Seamus Kaskela, Esq. or Adrienne O. Bell, Esq.) at (888) 299 – 7706 or at [email protected].

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 because “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.

A lead plaintiff is a representative party who acts on behalf of other class members in directing the litigation.  In order to be appointed as a lead plaintiff, the Court must determine that the class member’s claim is typical of the claims of other class members, and that the class member will adequately represent the class in the action.  Your ability to share in any recovery is not affected by the decision of whether or not to serve as a lead plaintiff.
