Lilly Diabetes Presents Phase II Blood Pressure and Heart Rate Data on Investigational GLP-1 Analog Candidate, Dulaglutide, in Patients with Type 2 Diabetes at the 27th American Society of Hypertension Scientific Meeting

NEW YORK, May 22, 2012 /PRNewswire/ -- Eli Lilly and Company (NYSE: LLY) today announced that dulaglutide, its investigational, long-acting glucagon-like peptide 1 (GLP-1) analog being studied as a once-weekly treatment for type 2 diabetes, met its primary endpoint of non-inferiority for mean 24-hour systolic blood pressure (SBP, or pressure while the heart contracts) after 16 weeks. The results came from a Phase II study that compared two doses of dulaglutide to placebo, using ambulatory blood pressure monitoring (ABPM) to characterize changes in blood pressure and heart rate. In addition, the 1.5 mg dulaglutide dose significantly reduced mean 24-hour SBP compared to placebo. These data were presented during a late-breaking clinical trial session at the 2012 Annual Scientific Meeting of the American Society of Hypertension (ASH) in New York.  

"Cardiologists and hypertension specialists are increasingly involved with evaluating the cardiovascular effects of diabetes medications," said Keith C. Ferdinand, M.D., FACC, FAHA, FASH, professor of clinical medicine, Section of Cardiology, Tulane University School of Medicine. "This study used the gold standard measurement technique of ABPM to evaluate the blood pressure and heart rate effects of dulaglutide, an investigational GLP-1 receptor agonist."

ABPM is a non-invasive, fully automated technique to measure blood pressure at specific intervals (usually every 15-30 minutes) throughout an entire 24-hour period. This approach allows clinicians to more accurately characterize a person's blood pressure levels throughout a normal day.

"We are very encouraged by these clinical trial results, in addition to the rest of the clinical trial data we've seen to date for dulaglutide," said Gwen Krivi, Ph.D., vice president, product development, Lilly Diabetes. "Dulaglutide is currently in Phase III clinical trials, where it will continue to be evaluated on its efficacy to lower blood glucose levels, overall safety, weight effects and effects on cardiovascular outcomes.  We believe dulaglutide, if approved, can bring significant benefits to people with type 2 diabetes."

Both dulaglutide doses were shown to be non-inferior (NI) (margin 3 mmHg) compared to placebo at week 16 for mean 24-hour SBP, which was the primary objective of the study. Since the NI criterion was satisfied, superiority testing was conducted, and the 1.5 mg dose demonstrated statistically significant reductions in mean 24-hour SBP compared to placebo.

• Dulaglutide 0.75 mg: -1.07 mmHg (97.3% CI: -2.83, 0.68)
• Dulaglutide 1.5 mg: -2.79 mmHg (97.3% CI: -4.58, -1.00)

Similar results were observed for comparisons at week 26.

The study also had several secondary objectives, including effects on mean 24-hour diastolic blood pressure (DBP, or pressure when the heart relaxes between beats) and mean 24-hour heart rate. For mean 24-hour DBP, the NI criterion (2.5 mmHg) was met for both dulaglutide doses compared to placebo at weeks 16 and 26.

For mean 24-hour heart rate, the 0.75 mg dulaglutide dose met the NI criterion (3 bpm) at both weeks 16 and 26 compared to placebo (1.62 bpm [97.3% CI: 0.32, 2.92] and 1.26 bpm [97.3% CI: -0.13, 2.64], respectively). The 1.5 mg dose did not meet the NI criterion at either week 16 (2.84 bpm [97.3% CI: 1.52, 4.16] or week 26 (3.50 bpm [97.3% CI: 2.10, 4.91]). This effect on heart rate is consistent with what has been observed for other compounds in the GLP-1 agonist class.

Both doses of dulaglutide demonstrated statistically significant reductions in HbA1c (average blood glucose levels over a three-month period) from baseline, compared to placebo, at weeks 16 and 26.

The most frequently reported adverse events were gastrointestinal (including diarrhea, nausea and vomiting). This is consistent with other GLP-1 agonists.

About the Study

This Phase II, randomized, double-blind, placebo-controlled, 26-week, parallel study included 755 patients with type 2 diabetes on one or more oral diabetes medications, of whom about 67 percent had a preexisting diagnosis of hypertension. Patients who were hypertensive took three or fewer antihypertensive medications, with a stable regimen for at least 30 days and no change on study. The study evaluated whether changes from baseline to week 16 in mean 24-hour SBP of dulaglutide 0.75 mg and dulaglutide 1.5 mg, dosed once-weekly, were NI to placebo, as measured by ABPM, using a NI margin of 3 mmHg. Superiority testing was performed if the statistical criterion for non-inferiority was satisfied.

About Diabetes

Approximately 25.8 million Americans[1] and an estimated 366 million people[2] worldwide have type 1 and 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.[3]
