Data presented at the American Diabetes Association 73rd Scientific Sessions® also showed statistically significant reductions in mean daily glucose and body weight in treated study subjects


Boehringer Ingelheim and Eli Lilly and Company have announced results of two Phase III 24week clinical trials of the investigational compound empagliflozin* added to metformin with and without the addition of sulphonylurea, respectively, in people with Type 2 Diabetes (T2D). These results showed statistically significant reductions in blood glucose among people who received empagliflozin, as measured by reductions in HbA1c (average blood glucose) after 24 weeks.1,2

Empagliflozin is a member of the sodium glucose cotransporter 2 (SGLT2) inhibitor class of drugs 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 reducing glucose reabsorption in the kidney.

The studies, presented at the American Diabetes Association (ADA) 73rd Scientific Sessions®, also demonstrated statistically significant reductions in key secondary endpoints, including mean daily glucose and body weight.1,2 Overall adverse events were reported in a similar percentage of patients treated with empagliflozin 10mg, empagliflozin 25mg and placebo, respectively.

"Metformin is the foundation of treatment for Type 2 Diabetes in people without clinically relevant renal impairment. However, many people don't meet their blood sugar target due to the progressive nature of the condition and have difficulties managing other risk factors such as weight and increased blood pressure," said Professor Klaus Dugi, Corporate Senior Vice President Medicine, Boehringer Ingelheim. "The results from this study of empagliflozin as an addon to metformin or metformin plus sulphonylurea therapies are promising for people with Type 2 Diabetes".

24week study with empagliflozin as an addon to metformin

In this 24week randomised, doubleblind, placebocontrolled trial, the addition of empagliflozin to a background of metformin showed a placeboadjusted reduction in HbA1c of 0.57% (p<0.001) and 0.64% (p<0.001) for empagliflozin 10mg (n=217) and 25mg (n=213), respectively, compared with placebo (n=207).1 The study also showed a statistically significant placeboadjusted reduction at 24 weeks in mean daily glucose of 8mg/dL (p=0.006) with empagliflozin 10mg and 12mg/dL (p<0.001) with empagliflozin 25mg.1 Empagliflozin 10mg and 25mg also had a significant placeboadjusted reduction in body weight of 1.63kg (p<0.001) and 2.01kg (p<0.001), respectively.1

Further analysis also showed reductions in systolic blood pressure by 4.5mmHg (p<0.001) with empagliflozin 10mg and 5.2mmHg (p<0.001) with empagliflozin 25mg versus placebo.1 Other analysis findings showed reductions in fasting plasma glucose by 20.04mg/dL (p<0.001) with empagliflozin 10mg and 22.28mg/dL (p<0.001) with empagliflozin 25mg versus placebo.1

Adverse events were reported by 57.1% and 49.5% of patients on empagliflozin 10mg and 25mg, respectively, and 58.7% of patients on placebo. Common adverse events included hypoglycaemia (plasma glucose ≤70mg/dL and/or requiring assistance reported in 1.8% of patients on empagliflozin 10mg, 1.4% on empagliflozin 25mg and 0.5% on placebo, none required assistance), as well as adverse events consistent with urinary tract infection (reported in 5.1% of patients on empagliflozin 10mg, 5.6% on empagliflozin 25mg and 4.9% on placebo) and genital infection (reported in 3.7% of patients on empagliflozin 10mg, 4.7% on empagliflozin 25mg and none on placebo).

24week study with empagliflozin as an addon to metformin and sulphonylurea

In this 24week randomised, doubleblind, placebocontrolled trial, the addition of empagliflozin to a background of metformin plus sulphonylurea therapy showed a placeboadjusted reduction in HbA1c of 0.64% (p<0.001) and 0.59% (p<0.001) for empagliflozin 10mg (n=225) and 25mg (n=216), respectively, compared with placebo (n=225).2 The study also showed a statistically significant placeboadjusted reduction at 24 weeks in mean daily glucose of 10.02mg/dL (p<0.001) and 13.06mg/dL (p<0.001) with empagliflozin 10mg and 25mg, respectively. Loss of weight greater than 5% was achieved by 27.6% and 23.6% of patients treated with empagliflozin 10mg and 25mg (p<0.001; 1.75kg and 1.99kg), respectively, as addon to metformin plus sulphonylurea, versus 5.8% on placebo.2

Adverse events were reported by 67.9%, 64.1% and 62.7% of patients on empagliflozin 10mg, 25mg and placebo, respectively. Common adverse events include hypoglycaemia (plasma glucose ≤70mg/dL and/or requiring assistance reported in 16.1% of patients on empagliflozin 10mg, 11.5% on empagliflozin 25mg and 8.4% on placebo; none required assistance), as well as adverse events consistent with urinary tract infection (reported in 10.3% of patients on empagliflozin 10mg, 8.3% on empagliflozin 25mg and 8.0% on placebo) and genital infection (reported in 2.7% of patients on empagliflozin 10mg, 2.3% on empagliflozin 25mg and 0.9% on placebo).
