PARIS, France, June 9, 2012 /PRNewswire/ -- Sanofi (EURONEXT: SAN and NYSE: SNY) announced today data demonstrating Lyxumia®* (lixisenatide), a once-daily investigational GLP-1 agonist, in combination with basal insulin plus oral anti-diabetic agents (OADs), significantly reduced HbA1c - glycated hemoglobin - in people with type 2 diabetes who were either new to insulin therapy (as early as 12 weeks after initiation) or already treated with insulin (for an average of 3.1 years).
Both GetGoal Duo 1(1) and GetGoal-L(2) studies achieved the primary efficacy endpoint of HbA1c improvement with an associated significant reduction in post-prandial glucose (PPG).
"Treatment with basal insulin and oral agents often controls fasting glucose and achieves glycemic goals for type 2 diabetes, but some patients may need additional treatment to further address post-prandial hyperglycemia. These results with lixisenatide are encouraging and provide scientific support as a potential approach for these patients," commented Dr. Matthew Riddle, Professor of Medicine in the Division of Endocrinology, Diabetes & Clinical Nutrition at Oregon Health & Science University, U.S.
"Efficacy and Safety of Once-Daily Lixisenatide Added on to Titrated Glargine plus Oral Agents in Type 2 Diabetes: GetGoal Duo 1 Study" [Abs A-4452]
GetGoal Duo 1 is a randomized, double-blind, multicenter study, assessing the efficacy and safety of lixisenatide, compared to placebo, in combination with insulin glargine and OADs (mostly metformin). During the 12-week run-in phase, 898 insulin-naive patients were treated with insulin glargine, which was titrated to reach a target fasting plasma glucose (FPG) of 80-100 mg/dL.
After the run-in phase, 446 patients with HbA1c >7% (despite controlled FPG levels) received either once-daily lixisenatide 20 microgram or placebo for 24 weeks while metformin and insulin glargine titration were continued.
HbA1c decreased on average from 8.60% to 7.60% during the run-in period with insulin glargine. The addition of lixisenatide led to a further significant HbA1c decrease to a mean value of 6.96% after 24 weeks compared to 7.3% in patients receiving placebo (p<0.0001). A significantly higher percentage of patients achieved target HbA1c <7.0% with lixisenatide compared to placebo (56.3% vs. 38.5%, respectively, p=0.0001).
Associated with HbA1c reduction, lixisenatide also significantly improved 2-hour PPG, after a standardized breakfast, with a mean difference of -3.16 mmol/L (p<0.0001) compared to placebo. The mean difference in change in body weight between the lixisenatide and placebo groups was
-0.89 kg (p=0.0012).
Incidence of symptomatic hypoglycemia was 22.4% among patients receiving lixisenatide vs. 13.5% in the placebo group. Other common adverse events in the lixisenatide group were nausea and vomiting, which occurred in 27.4% and 4.9%, respectively, compared to placebo (9.4% and 1.3%, respectively). Eighty-eight percent of patients in the lixisenatide arm reached and remained on the 20 microgram maintenance dose.
"Efficacy and Safety of Once-Daily Lixisenatide in Type 2 Diabetes Insufficiently Controlled with Basal Insulin +/- Metformin: GetGoal-L Study" [A-4379]
Also announced at the American Diabetes Association 72nd congress were data from GetGoal-L, a 24-week randomized, double-blind multicenter, placebo-controlled study of 495 people with type 2 diabetes, insufficiently controlled on basal insulin with or without metformin. In the lixisenatide arm, mean HbA1c was significantly reduced from baseline compared to placebo (-0.74% vs. -0.38%, p=0.0002) along with a significant decrease in mean 2-hour PPG (-5.54 mmol/L vs. -1.72 mmol/L, p<0.0001), after a standardized breakfast.
Patients in the lixisenatide arm of the study also experienced a significant mean reduction in body weight compared to placebo (-1.8 kg vs. -0.52 kg, p<0.0001). The incidence of per protocol symptomatic hypoglycemia was 27.7% for lixisenatide vs. 21.6% for placebo. Severe hypoglycemia occurred in 1.2% of patients treated with lixisenatide compared to none with placebo. Other common adverse events were nausea (26.2%), vomiting (8.2%), and diarrhea (7.3%).
Pierre Chancel, Senior Vice-President, Global Diabetes at Sanofi, added: "Due to the complexities in type 2 diabetes management, it is important to address the needs of all patients who are not at goal HbA1c, despite achieving, or nearly achieving, controlled fasting plasma glucose (FPG) targets with basal insulin. The results from GetGoal Duo 1 and GetGoal-L are encouraging and we will continue to evaluate Lyxumia® (lixisenatide), with its pronounced post-prandial glucose (PPG) lowering effect, for its potential use in people with type 2 diabetes."
The European Medicines Agency (EMA) acknowledged receipt of the Marketing Authorization Application filing for Lyxumia® (lixisenatide) in November 2011. Submission for regulatory approval of lixisenatide in the U.S. is expected in Q4 2012.
The full study results from the GetGoal program are planned for publication in a peer-reviewed medical journal later this year.
Lixisenatide, a glucagon-like peptide-1 agonist (GLP-1), is in development for the treatment of patients with type 2 diabetes mellitus. Lixisenatide was in-licensed from Zealand Pharma A/S (Copenhagen, Denmark), www.zealandpharma.com. Lyxumia® is the intended trademark of lixisenatide. Lixisenatide is not currently approved or licensed anywhere in the world.
GLP-1 is a naturally-occurring peptide that is released within minutes of eating a meal. It is known to suppress glucagon secretion from pancreatic alpha cells and stimulate insulin secretion by pancreatic beta cells.
The GetGoal phase III clinical program provides data for lixisenatide in adults with type 2 diabetes treated in monotherapy, with various oral anti-diabetic agents or in combination with basal insulin. The GetGoal program started in May 2008, has enrolled more than 5,000 patients and serves as support for the application for regulatory approval of lixisenatide.
*Lyxumia is the proprietary name submitted to the EMA for the company's investigational GLP-1 agonist lixisenatide. The proprietary name for lixisenatide in the United States is under consideration.
Diabetes is a long-term disease that occurs either when the pancreas does not produce enough insulin (the hormone that regulates blood glucose concentrations), or when the body cannot effectively use the insulin it produces, or both. This results in raised blood glucose concentrations (hyperglycemia).Over time, uncontrolled hyperglycemia leads to the macrovascular and microvascular complications of diabetes.(4) Macrovascular complications, which affect the large blood vessels, include heart attack, stroke and peripheral vascular disease. Microvascular complications affect the small blood vessels of the eyes (retinopathy), kidney (nephropathy) and nerves (neuropathy). The incidence of type 2 diabetes is growing at an alarming rate, with over 310 million people worldwide living with the condition today.(3)
