Robbins Geller Rudman & Dowd LLP Files Class Action Suit Against Cempra, Inc.

SAN DIEGO, Nov. 22, 2016

If you wish to serve as lead plaintiff, you must move the Court no later than 60 days from November 4, 2016.  If you wish to discuss this action or have any questions concerning this notice or your rights or interests, please contact plaintiff's counsel, Darren Robbins of Robbins Geller at 800/449-4900 or 619/231-1058, or via e-mail at djr@rgrdlaw.com.  If you are a member of this class, you can view a copy of the complaint as filed at http://www.rgrdlaw.com/cases/cempra/.  Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member.

The complaint charges Cempra and certain of its officers and directors with violations of the Securities Exchange Act of 1934.  Cempra is a clinical-stage biopharmaceutical company that develops antibiotics for the treatment of infectious diseases.  Cempra's lead product, solithromycin, is being developed in oral capsule, intravenous and suspension formulations for the treatment of community-acquired bacterial pneumonia ("CABP"), as well as for other indications.

The complaint alleges that throughout the Class Period, defendants violated the federal securities laws by disseminating false and misleading statements to the investing public.  Specifically, defendants misleadingly informed investors that solithromycin was not associated with liver toxicity and drug-induced liver injury.  As a result of defendants' false and misleading statements, Cempra stock traded at artificially inflated prices during the Class Period, reaching a high of $32.81 per share on November 25, 2015.

Then, on November 2, 2016, the U.S. Food and Drug Administration released a report analyzing Cempra's clinical development program of solithromycin to treat CABP, which highlighted a significant safety signal for hepatotoxicity and drug-induced liver injury.  As a result of this news, the price of Cempra stock dropped $11.35 per share to close at $7.30 per share on November 2, 2016, a one-day decline of nearly 61% on volume of 20.7 million shares.

Plaintiff seeks to recover damages on behalf of all purchasers of Cempra common stock during the Class Period (the "Class").  The plaintiff is represented by Robbins Geller, which has extensive experience in prosecuting investor class actions including actions involving financial fraud.
