RIDGEFIELD, Conn. and
June 22, 2013 /PRNewswire/ -- Boehringer Ingelheim Pharmaceuticals, Inc. and Eli Lilly and Company (NYSE: LLY) today announced results of a 24-week phase III clinical trial, which showed that treatment with the investigational compound empagliflozin* as monotherapy produced statistically significant reductions in HbA
1c (average blood glucose) versus placebo, in adults with type 2 diabetes (T2D) who had never received treatment or had not received treatment in the last 12 weeks.
Empagliflozin is a member of the sodium glucose co-transporter-2 (SGLT2) inhibitor class of compounds, and is being investigated for the reduction of blood glucose levels in adults with T2D. The emerging SGLT2 inhibitor class removes excess glucose through the urine by blocking glucose re-absorption by the kidney.
Presented at the American Diabetes Association 73rd Scientific Sessions
®, the study in people with T2D (n=899) investigated the safety and efficacy of two doses (10 mg and 25 mg) of empagliflozin for 24 weeks.
1 Results of the primary endpoint showed placebo-adjusted reductions in HbA
1c from baseline to week 24 of 0.74 percent and 0.85 percent (p<0.001) for the 10 mg and 25 mg doses, respectively.
1 Sitagliptin 100 mg (which was used as an active comparator to validate the trial design and not for a head-to-head comparison with empagliflozin) showed a reduction in HbA
1c of 0.73 percent compared to placebo (p<0.001).
Study findings at 24 weeks also showed significant improvements with empagliflozin in secondary endpoints
- Findings included statistically significant placebo-adjusted reductions in systolic blood pressure of 2.6 mmHg for empagliflozin 10 mg (p=0.023) and 3.4 mmHg for empagliflozin 25 mg (p=0.003).
1 Sitagliptin 100 mg did not show a statistically significant change in systolic blood pressure versus placebo.
- After 24 weeks, body weight significantly decreased by 4.25 lbs and 4.74 lbs (p<0.001) in patients treated with empagliflozin 10 mg and 25 mg, respectively, versus placebo.
1 Sitagliptin 100 mg showed a weight increase of 1.15 lbs versus placebo (p=0.036).
- Changes in diastolic blood pressure were statistically significant for the empagliflozin 25 mg treatment group only (1.9 mmHg reduction versus 0.5 mmHg reduction for placebo, p=0.030).
"Adults with type 2 diabetes have an increased risk of developing serious health problems and are tasked with managing their disease," said
, MD, PhD, vice president, metabolic-clinical development and medical affairs, Boehringer Ingelheim Pharmaceuticals, Inc. "With more than 330 million people worldwide living with type 2 diabetes, varied treatment options are needed to help these people better manage their condition."
The proportions of patients reporting drug-related adverse events from each study group were: 12.1 percent, empagliflozin 10 mg; 17.5 percent, empagliflozin 25 mg; 7.4 percent, placebo; and 8.5 percent, sitagliptin.
Adverse events consistent with urinary tract infection were reported in 6.7 percent and 5.4 percent of randomized patients on empagliflozin 10 mg and 25 mg, respectively, and in 5.2 percent on placebo and 4.9 percent on sitagliptin.
Adverse events consistent with genital infection were reported in 3.1 percent and 4.0 percent of patients on empagliflozin 10 mg and 25 mg, respectively, and in 0.0 percent on placebo and 0.9 percent on sitagliptin.
One patient in each study group experienced a confirmed hypoglycemic event, none of which required assistance.
Additionally, a subset of patients with baseline HbA
greater than 10 percent (mean=11.5 percent, N=87), which was above the study inclusion criteria, were placed on open-label empagliflozin 25 mg for 24 weeks and obtained a mean reduction of 3.7 percent from baseline HbA
Drug-related adverse events were reported by 12.6 percent of patients included in this subset.
About the study
The 24-week, randomized, double-blind, placebo-controlled trial investigated the safety and efficacy of empagliflozin in drug-naive patients with T2D. Patients were randomized to receive empagliflozin 10 mg (n=224) or 25 mg per day (n=224), sitagliptin 100 mg per day (n=223) or placebo (n=228) for 24 weeks. Patients with HbA
more than 10 percent (n=87) received open-label empagliflozin 25 mg per day for 24 weeks. The primary endpoint of the trial was change from baseline HbA
at week 24. Secondary endpoints were change from baseline in body weight, systolic blood pressure and diastolic blood pressure at week 24.
About the Empagliflozin Phase III Clinical Trial Program
Empagliflozin is being investigated in adults with T2D in a phase III clinical trial program that has enrolled more than 14,500 patients. This program includes more than 10 multinational clinical trials, including a large cardiovascular outcomes trial.
Approximately 25.8 million Americans
and an estimated 371 million people worldwide
have type 1 or type 2 diabetes. T2D is the most common type, accounting for an estimated 90 to 95 percent of all diabetes cases.
Diabetes is a chronic condition that occurs when the body does not properly produce or use the hormone insulin.
Diabetes was estimated to cost the U.S.
in direct medical costs and reduced productivity in 2012.
