Their Investment in Sanofi Pharmaceuticals, Inc. of Class Action Law Suit and
Upcoming Deadline -- GCVRZ

NEW YORK, Jan. 3, 2014 (GLOBE NEWSWIRE) -- Pomerantz Grossman Hufford
Dahlstrom & Gross LLP has filed a class action lawsuit against Sanofi
Pharmaceuticals, Inc. ("Sanofi" or the "Company") (Nasdaq:GCVRZ) and certain
of its officers. The class action, filed in United States District Court,
Southern District of New York, and docketed under 13-cv-8991, is on behalf of
a class consisting of all persons or entities who purchased or otherwise
acquired Contingent Value Rights-2011 ("CVR's") related to the performance of
the Company's anti Multiple Sclerosis ("MS") drug Lemtrada. (CUSIP: 80105N113)
between March 6, 2012 and November 7, 2013 both dates inclusive (the "Class
Period"). This class action seeks to recover damages against the Company and
certain of its officers and directors as a result of alleged violations of the
federal securities laws pursuant to Sections 10(b) and 20(a) of the Securities
Exchange Act of 1934 and Rule 10b-5 promulgated thereunder.

If you are a shareholder who purchased the CVR's during the Class Period, you
have until February 10, 2014 to ask the Court to appoint you as Lead Plaintiff
for the class. A copy of the Complaint can be obtained at

Sanofi is a global pharmaceutical group engaged in the research, development,
manufacture and marketing of healthcare products. Sanofi is the fifth largest
pharmaceutical group in the world and the third largest pharmaceutical group
in Europe. The company operates three main product segments: Pharmaceuticals,
Human Vaccines, and Animal Health.

The Complaint alleges that throughout the Class Period, Defendants made
materially false and misleading statements regarding the Company's business
and operations. Specifically, during the Class Period, Defendants
misrepresented to investors the efficacy and safety of the Company's MS drug
Lemtrada. The Company also misled investors regarding the design of its two
Lemtrada pivotal trials, the 323 and 324 trials, specifically failing to
disclose that the trials contained high levels of placebo effect and observer
bias which tainted the results, and thereby lowered the likelihood of approval
of Lemtrada by the FDA.

On November 8, 2013, the FDA Advisory Committee on Peripheral and Central
Nervous System Drugs issued a briefing report (the, "Briefing Report") in
advance of its November 13, 2013 hearing. The Briefing Report sharply
criticized the Company's submission to the FDA, and found that, "significant
concerns exist regarding the safety profile of alemtuzumab [Lemtrada] and the
adequacy of the efficacy data." On this news, Sanofi's CVRs declined $1.23 per
share or nearly 62%, to close at $0.77 per share on November 8, 2013 on volume
of over 30 million shares.
