Results from the ELIXA trial were presented in June at the 75th Scientific Sessions of the American Diabetes Association.

FDA has accepted a new drug application (NDA) for Sanofi’s lixisenatide, a GLP-1 receptor agonist, marking the first time that such a filing included data from a cardiovascular (CV) outcomes trial, the company announced September 29, 2015.

Lixisenatide, approved in Europe under the brand name Lyxumia, treats adults with type 2 diabetes; it has been studied both alone and in combination with Sanofi’s mainstay insulin, Lantus. The NDA announcement is based on results from the Get-Goal clinical program, whose results were reported in 2014,1,2 and whose CV results were presented in June at the 75th Scientific Sessions of the American Diabetes Association (ADA).3

In support of the NDA, Sanofi included results of 11 multinational, phase 3 clinical trials, in which the main efficacy endpoints were met, with reductions in glycated hemoglobin (A1C) ranging from 0.7% to 1.0%.1 Results from one of those trials, reported in Diabetic Medicine in February 2014, found that lixisenatide, given once daily in both 1- and 2-step dose increases, significantly improved A1C at week 24 compared with placebo and allowed more patients to achieve an A1C of less than 7.0%.2

What sets lixisenatide apart is the ELIXA trial, which were the first CV results from the glucagon-like peptide 1 (GLP-1) receptor agonist class.3 The trial found that there were no CV benefits or risks from the therapy, which works in the pancreas by suppressing glucagon secretion from the alpha cells and stimulating glucose-dependent insulin by the beta cells. Of note, the ELIXA trial found no risk of pancreatic injury, something that has been of particular concern to FDA.

US regulators have been requiring long-term CV trials for new diabetes and cholesterol medications in the wake of embarrassing events in the prior decade. In one episode, the agency was forced to limit sales of rosiglitazone after that blockbuster drug was linked to risk of heart attacks based on a report published in the New England Journal of Medicine.4 For example, when the FDA recently approved the new class of cholesterol medications, the PCSK9 inhibitors, it limited indications while awaiting results of long-term safety trials, which are expected in 2017. Indications in Europe for these same drugs are much broader.5

In a statement, Sanofi’s Pierre Chancel, senior vice president and head of Global Diabetes, said, “Sanofi’s integrated portfolio of marketed products provides treatment, monitoring and support at every stage of the diabetes journey. Lixisenatide is a critical element of this portfolio, and we look forward to working with the FDA during the review process with the goal of bringing lixisenatide to patients in the United States.”1 References
