Feb 24, 2016, 06:00 ET from Block & Leviton LLP

BOSTON, Feb. 24, 2016 /PRNewswire/ -- Block & Leviton LLP (, a Boston-based law firm representing investors nationwide, is investigating possible violations of the federal securities laws by PTC Therapeutics, Inc. (NASDAQ: PTCT) ("PTC" or the "Company") and/or its officers and directors.

Shares of PTC Therapeutics plummeted yesterday by over 60% after the Company announced that it had received a "refusal to file" letter from the FDA regarding its New Drug Application (NDA) for its lead drug candidate, Translarna.

Analysts describe refusal-to-file letters as "rare and embarrassing" and issued only when "the application was not sufficiently complete to permit a substantive review."  Notably, insiders at PTC Therapeutics have been engaging in significant sales of their PTC shares prior to this news.

Block & Leviton's investigation seeks to determine whether PTC and/or any of its officers or directors violated federal securities laws in connection with disclosures concerning the NDA process for Translarna.
