Lixisenatide significantly reduces hba1c without increasing hypoglycemia in patients uncontrolled on sulfonylureas

Sanofi-aventis Press Release
Lixisenatide Significantly Reduces HbA1c Without Increasing Hypoglycemia in Patients Paris, France – April 12, 2011 – Sanofi-aventis (EURONEXT: SAN and NYSE: SNY) announced
today that lixisenatide, a once-daily GLP-1 receptor agonist under development for people with
Type 2 diabetes, achieved its primary efficacy objective of significant HbA1c reduction and
improved glycemic control from baseline versus placebo. The top-line results also showed that
people treated with lixisenatide had a significant decrease in body weight.
The GetGoal-S trial, one of nine studies in the GetGoal Phase III clinical program, investigated the
efficacy and safety of lixisenatide as an add-on therapy for people with Type 2 diabetes whose
condition was inadequately controlled by sulfonylureas, with or without metformin. GetGoal-S was a
randomized (double-blind), placebo-controlled study with a 24-week main treatment period. A total
of 859 patients were randomized to receive either lixisenatide or placebo. Both groups received a
step-wise increase in dose, up to a maintenance dose of 20µg daily.
Top-line results of the GetGoal-S study showed that people in the lixisenatide group experienced a
significant reduction in their HbA1c levels, with a -0.74% difference versus placebo (p<0.0001) at
week 24. Lixisenatide also significantly improved patients’ 2-hour post-prandial glucose (p<0.0001)
and fasting plasma glucose (p<0.0001) levels. In addition, people treated with lixisenatide had a
significant decrease in body weight (p<0.0001), versus those receiving placebo.
Results from GetGoal-S also showed that lixisenatide did not significantly increase the risk of
symptomatic hypoglycemia at week 24 (p=0.23), compared with placebo.
“The results of GetGoal-S are another positive step for lixisenatide and reinforce the efficacy and
safety profile of this new GLP-1,” said Pierre Chancel, Senior Vice President, Global Diabetes
Division, sanofi-aventis. “The demonstration of benefits in terms of improving glycemic control and
reducing body weight in this population, without significantly increasing the risk of symptomatic
hypoglycemia, confirmed that lixisenatide is a potential important new therapy in Type 2 diabetes to
help people manage their condition more effectively.”

The full study findings are planned to be presented at the 47th European Association for the Study
of Diabetes (EASD) Annual Meeting, in September 2011.
