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, Conn. and INDIANAPOLIS, June 9, 2012 /PRNewswire/-- 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. 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. 
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.
Approximately 25.8 million Americans and an estimated 366 million people worldwide 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. Diabetes is a chronic disease that occurs when the body either does not properly produce, or use, the hormone insulin.
