90-week data suggest sustained glucose reduction and weight loss with 
investigational SGLT-2 inhibitor, empagliflozin 
 
Study evaluating the efficacy and safety of empagliflozin up to 90 weeks 
presented during a late-breaking session at the American Diabetes Association's 
72nd Scientific Sessions® 
 
Ridgefield, CT and Indianapolis, IN, June 9, 2012 - Boehringer Ingelheim 
Pharmaceuticals, Inc. and Eli Lilly and Company (NYSE: LLY) presented results 
that showed empagliflozin (BI 10773), alone or as an add-on to metformin, 
reduced hemoglobin A1c (HbA1c or A1C) levels, fasting plasma glucose (FPG) 
levels and body weight when given to adults with type 2 diabetes for up to 90 
weeks. A1C is measured in people with diabetes to provide an index of blood 
glucose control for the previous two to three months. The new data, from a 
phase 2b open-label extension study, were presented during a late-breaking 
session at the American Diabetes Association's (ADA's) 72nd Scientific Sessions 
®. 
 
Empagliflozin inhibits SGLT-2, which blocks glucose reuptake in the kidney, 
thereby removing excess glucose through the urine. 
 
"These new findings provide additional information about the use of 
empagliflozin in type 2 diabetes, and support the phase 3 trials that are 
underway to confirm the drug's efficacy and safety profile," said John Smith, 
M.D., Ph.D., senior vice president for clinical development and medical 
affairs, Boehringer Ingelheim Pharmaceuticals, Inc. 
 
In the open-label study, adults with type 2 diabetes (n=659) who participated 
in one of two 12-week, blinded, dose-finding empagliflozin trials, were treated 
for an additional 78 weeks with open-label empagliflozin 10 mg or 25 mg 
(monotherapy or add-on to metformin), metformin alone, or sitagliptin as add-on 
to metformin. 
 
At week 90, decreases in average A1C levels (percent), FPG levels (mg/dL), and 
body weight (kg, weight) were observed with empagliflozin 10 mg alone (-0.34; 
-30.4; -2.24, respectively) and 25 mg alone (-0.47; -27.8; -2.61, 
respectively), versus metformin (-0.56; -26.0; -1.28, respectively). When used 
as an add-on to metformin, empagliflozin showed reductions versus sitagliptin 
on A1C levels (-0.34 EMPA 10 mg; -0.63 EMPA 25 mg; and -0.40 sitagliptin); FPG 
levels (-21.3 EMPA 10 mg; -31.8 EMPA 25 mg; and -15.6 sitagliptin); and body 
weight (-3.14 EMPA 10 mg; -4.03 EMPA 25 mg; and -0.41 sitagliptin). 
 
"The alliance is leveraging the collective scientific expertise of two leading 
research-driven pharmaceutical companies to address patient needs arising from 
the growing global diabetes epidemic," said Professor Klaus Dugi, Corporate 
Senior Vice President Medicine, Boehringer Ingelheim GmbH. "We are committed to 
developing medications to help patients with diabetes throughout the course of 
their condition." 
 
The study showed empagliflozin (10 mg or 25 mg) was generally well-tolerated. 
When given for a treatment duration of at least 78 weeks and for up to 90 
weeks, adverse events (AEs) were reported in 63.2 to 74.1 percent of patients 
on empagliflozin and in 69.6 percent of patients on metformin alone or 
sitagliptin plus metformin.1 More than 90 percent of these AEs were of mild or 
moderate severity. Between 0.9 and 3.6 percent of patients on empagliflozin 
reported hypoglycemic events, versus 7.1 percent on metformin only and 5.4 
percent on sitagliptin. AEs related to urinary tract infections were reported 
in 3.8 to 12.7 percent of patients on empagliflozin, 3.6 percent of patients on 
metformin only, and 12.5 percent of patients on sitagliptin. AEs related to 
genital infections were reported in 3.0 to 5.5 percent of patients on 
empagliflozin, 1.8 percent of patients on metformin only, and none of the 
patients on sitagliptin. 
 
Empagliflozin is currently in phase 3 clinical development with over 14,500 
patients planned to be enrolled. 6 
 
Safety and Efficacy of Empagliflozin as Monotherapy or Add-On to Metformin in a 
78-Week Open-Label Extension Study in Patients With Type 2 Diabetes 
 
In this extension study, patients treated with 10 mg or 25 mg of empagliflozin 
(monotherapy or add-on to metformin), metformin alone, or sitagliptin as add-on 
to metformin in one of two 12-week trials continued on the same treatment for 
an additional 78 weeks. Patients in the 12-week trial who had received 1, 5 or 
50 mg of empagliflozin or placebo were randomized to 78 weeks of treatment with 
either 10 mg or 25 mg of empagliflozin (monotherapy [106 on 10 mg; 109 on 25 
mg] or add-on to metformin [166 on 10 mg and 166 on 25 mg]), metformin only 
(56) or sitagliptin (56). Results for empagliflozin monotherapy were compared 
with those of patients treated with metformin alone, while data among patients 
on empagliflozin plus metformin were compared with those of patients on 
sitagliptin plus metformin. 
 
About Diabetes 
 
Approximately 25.8 million Americans3 and an estimated 366 million people 
worldwide4 have type 1 or type 2 diabetes. Type 2 diabetes is the most common 
type, accounting for an estimated 90 to 95 percent of all diabetes cases.3 
Diabetes is a chronic disease that occurs when the body either does not 
properly produce, or use, the hormone insulin.5
