PRESS RELEASE

Lyxumia® (lixisenatide)* in Combination with Basal Insulin plus
Oral Anti-Diabetics Significantly Improved Glycemic Control
– Data show investigational GLP-1 receptor agonist delayed gastric emptying and
significantly reduced post-prandial glucose –
– Results from the GetGoal Duo 1 and GetGoal-L Phase III studies also presented at
the annual EASD meeting –

Paris, France – October 2, 2012 – Sanofi (EURONEXT: SAN and NYSE: SNY) today announced
results from a study showing that the mechanism of action of once-daily Lyxumia® (lixisenatide)
significantly delayed gastric emptying, a process accompanied by significant post-prandial glucose
(PPG) lowering. These data were presented at the 48th Annual Meeting of the European
Association for the Study of Diabetes (EASD) in Berlin, alongside Phase III trial results that support
the clinical rationale for lixisenatide as a potential once-daily GLP-1 receptor agonist (RA) in
combination with basal insulin.
"Effects of lixisenatide once daily on gastric emptying and its relationship to postprandial
glycaemia in type 2 diabetes mellitus" [Abs 808-EASD]


Treatment after a standardized breakfast with a final dose of once-daily 20μg lixisenatide and up to
two OADs contributed significantly to slowing the rate of gastric emptying, compared with placebo
(p=0.0031) in this 28-day, randomized, double-blind, placebo-controlled, parallel-group study in
patients with type 2 diabetes (lixisenatide n=19; placebo n=22; final dose reached after titrating from
5–20μg with 2.5μg increments every 4 days). This had a pharmacodynamic effect on blood glucose
levels throughout the day. Delayed gastric emptying is associated with lower PPG levels. At day 28,
PPG was significantly reduced after a standardized breakfast (p<0.0001), after lunch (p=0.0004)
and after dinner (p=0.0082).No such relationship was found for placebo.

"Gastric emptying, the rate at which food passes through the stomach into the intestine, is
modulated by GLP-1 and is a major determinant of PPG in both health and diabetes,"
explained
Professor Michael Horowitz from the Royal Adelaide Hospital, Australia. "Not all GLP-1 RAs are the
same. Those, such as lixisenatide, that are associated with a sustained deceleration of gastric
emptying with a consequent significant reduction in PPG levels are likely to best complement the
FPG-lowering effect of basal insulin to help type 2 diabetes patients achieve their target HbA ."



"Once-daily lixisenatide added on to consistently titrated insulin glargine plus oral agents in
type 2 diabetes: The GetGoal Duo 1 study" [Abs 807-EASD]
and "Efficacy and safety of
once-daily lixisenatide in type 2 diabetes insufficiently controlled with basal insulin ±
metformin: GetGoal-L study" [Abs 3-EASD]
Also presented at EASD (and previously at the American Diabetes Association [ADA] scientific
sessions 2012) were results from the GetGoal Duo 11 and GetGoal-L2 studies, which demonstrated
that lixisenatide in combination with basal insulin plus oral anti-diabetic agents (mostly metformin in
GetGoal Duo 1, with or without metformin in GetGoal-L) significantly reduced HbA1c – glycated


hemoglobin A1c – in people with type 2 diabetes who were either new to insulin therapy (as early as
12 weeks after initiation) or already treated with insulin (for an average of 3.1 years), respectively.
GetGoal Duo 1 and GetGoal-L both achieved the primary efficacy endpoint of HbA1c improvement
with an associated significant reduction in PPG. Results showed that lixisenatide caused mild and
transient nausea and vomiting, the most common adverse events, and a limited additional or
comparable risk of hypoglycemia.
These studies are part of the GetGoal Phase III clinical program for lixisenatide, which includes a
broad range of patients with type 2 diabetes, including a large number of patients treated with basal
insulin (706 patients in three trials).3
To achieve target blood glucose levels, both fasting plasma glucose (FPG) and PPG need to be
addressed.4 Despite basal insulin therapies providing effective FPG control, due to disease
progression some patients over time might no longer be at their glycemic targets and need
additional treatment to further address uncontrolled HbA1c. A GLP-1 that has a pronounced PPG
effect in combination with basal insulin may therefore be beneficial for those patients.
"The positive data for Lyxumia® (lixisenatide) are of particular significance as the new Position
Statement of the ADA and EASD recognizes that combining therapies may be helpful,"
said Pierre
Chancel, Senior Vice-President, Global Diabetes at Sanofi. "Taken together, the results from the
GetGoal Duo 1 and GetGoal-L trials, as well as lixisenatide's significant effect on gastric emptying
and PPG, support the clinical rationale for the potential use of our investigational GLP-1 receptor
agonist in combination with basal insulin to improve glycemic control by addressing both PPG and
FPG."

The European Medicines Agency (EMA) acknowledged receipt of the Marketing Authorization
Application filing for Lyxumia® (lixisenatide) in November 2011. Submission for regulatory approval
of lixisenatide in the U.S. is expected in December 2012.
About Lyxumia® (lixisenatide)
*Lixisenatide, a glucagon-like peptide-1 receptor agonist (GLP-1 RA), is in development for the
treatment of patients with type 2 diabetes mellitus. Lixisenatide was in-licensed from Zealand
Pharma A/S (NASDAQ OMX Copenhagen: ZEAL), www.zealandpharma.com. Lyxumia® is the
proprietary name submitted to the EMA for the company's investigational GLP-1 RA lixisenatide.
The proprietary name for lixisenatide in the United States is under consideration. Lixisenatide is not
currently approved or licensed anywhere in the world.
GLP-1 is a naturally-occurring peptide hormone that is released within minutes after eating a meal.
It is known to suppress glucagon secretion from pancreatic alpha cells and stimulate glucose-
dependent insulin secretion by pancreatic beta cells.
The GetGoal Phase III clinical program provides data for lixisenatide in adults with type 2 diabetes
treated in monotherapy, with various oral anti-diabetic agents or in combination with basal insulin.
The GetGoal program started in May 2008, has enrolled more than 5,000 patients and serves as
support for the application for regulatory approval of lixisenatide.
About Diabetes
Diabetes is a chronic disease that occurs as type 1 diabetes, which is an autoimmune disease
characterized by the lack of insulin (the hormone that regulates blood glucose concentrations)
production by the pancreas, and type 2, a metabolic disorder in which there are two main biological
defects: a deficient production of insulin and reduced ability of the body to respond to the insulin
being produced. Type 1 and type 2 diabetes are characterized by an increase in blood glucose


concentrations (hyperglycemia). Over time, uncontrolled hyperglycemia leads to the macrovascular
and microvascular complications of diabetes. Macrovascular complications, which affect the large
blood vessels, include heart attack, stroke and peripheral vascular disease. Microvascular
complications affect the small blood vessels of the eyes (retinopathy), kidney (nephropathy) and
nerves (neuropathy). More than 18 million people worldwide are living with type 1 diabetes.5 And,
the incidence of type 2 diabetes is growing at an alarming rate, with nearly 348 million people
worldwide living with the condition today.5
