Sanofi Announces Results of ORIGIN, the World's Longest and Largest Randomized Clinical Trial in Pre- and Early Diabetes
PARIS, France, June 11, 2012 /PRNewswire/ -- Sanofi (EURONEXT: SAN and NYSE: SNY) announced today results from the landmark ORIGIN trial (Outcome Reduction with Initial Glargine Intervention), which showed that Lantus® (insulin glargine [rDNA] injection) had no statistically significant positive or negative impact on cardiovascular (CV) outcomes versus standard care during the study period. Results also showed that insulin glargine delayed progression from pre-diabetes to type 2 diabetes and there was no association between insulin glargine use and increased risk of any cancer. The study findings were presented today at the American Diabetes Association 72nd Scientific Sessions and also published online in the New England Journal of Medicine (NEJM).
ORIGIN was a six-year randomized clinical trial designed to assess the effects of treatment with insulin glargine versus standard care on CV outcomes. The study involved over 12,500 participants worldwide with pre-diabetes or early type 2 diabetes mellitus and high CV risk, with 6,264 participants randomized to receive insulin glargine titrated to achieve fasting normoglycemia. The co-primary endpoints were the composite of CV death, or non-fatal myocardial infarction, or non-fatal stroke; and the composite of CV death, or non-fatal myocardial infarction, or non-fatal stroke, or revascularization procedure, or hospitalization for heart failure.
"We now know more about insulin glargine than about any other glucose lowering drug with respect to future health outcomes," commented Dr. Hertzel Gerstein, McMaster University, Hamilton, Ontario/Canada and Principal Investigator of the ORIGIN trial. "Specifically, it maintains excellent glycemic control, slows progression of dysglycemia and has no long-term serious health effects. Moreover, this academically led and analyzed trial is an excellent example of collaboration between industry and academia."
The study demonstrated that achieving fasting normoglycemia did not affect CV outcomes in these participants with early dysglycemia during the study period (first co-primary endpoint: Hazard Ratio [HR]: 1.02; p = 0.63, NS; and second co-primary endpoint: HR: 1.04; p = 0.27, NS).
Insulin glargine achieved targeted long-term glycemic control (median fasting plasma glucose 5.2 mmol/L and HbA1c 6.2%), which was sustained over the 6.2 years of follow-up.
There was no association between insulin glargine and increased risk of any cancer (HR: 1.00; p = 0.97, NS). Neither analysis of all cancers combined, nor analysis of any organ-specific type of cancer, suggested an increased risk for the users of insulin glargine.
Results showed that insulin glargine delayed progression from pre-diabetes (IFG or IGT) to type 2 diabetes mellitus by 28% (HR: 0.72; p = 0.006). Other secondary outcomes included a composite microvascular outcome (metrics of kidney or eye disease; (HR: 0.97; p = 0.43), and all-cause mortality (HR: 0.98; p = 0.70).
"In patients with pre-diabetes or early type 2 diabetes and high CV risk, ORIGIN shows that it is possible to maintain low and stable HbA1c levels that are close to normal over a long time, and to potentially delay the progression from pre-diabetes to diabetes. Sanofi is proud to have sponsored this trial as a vital contribution to improving understanding of diabetes and the impact of long-term glycemic control," commented Riccardo Perfetti, MD, Vice President Medical Affairs, Global Diabetes, Sanofi.
Hypoglycemic events were infrequent. In the insulin glargine arm, the rate of severe hypoglycemia was 0.01 episodes per patient-year of exposure versus 0.003 episodes per patient-year for standard care. Rates for overall hypoglycemia with insulin glargine were 16.7 patients with events per 100 patient-years of exposure versus 5.2 patients with events per 100 patient-years for standard care. In addition, weight gain was modest for participants in the insulin glargine arm, at an average of 3.5 pounds over the duration of the study.
ORIGIN investigated the use of insulin glargine in a population in which insulins are not typically used,(1) providing new data on the potential benefits and risks of initiation of insulin glargine therapy earlier in the course of diabetes (average disease duration since diagnosis at entry in trial: 5.8 years).
"Our commitment to funding this vitally important long-term trial exemplifies our aim to help identify new ways of treating and understanding diabetes," commented Pierre Chancel, Senior Vice President, Global Diabetes, Sanofi. "I am pleased to announce that Sanofi will extend the observations of ORIGIN by an additional two years. All of these data will build on the extensive Lantus® evidence in more than 47 million real-life patient-years(2) and over 10 years of clinical experience involving 80,000 participants in clinical development programs."
The extension of the observations of ORIGIN will be called ORIGINALE (Outcome Reduction with an Initial Glargine Intervention and Legacy Effect).
ORIGIN (Outcome Reduction with Initial Glargine Intervention) is a unique, six-year landmark cardiovascular (CV) outcomes trial, evaluating Lantus® (insulin glargine) versus standard care in over 12,500 individuals who are at high CV risk with pre-diabetes or early type 2 diabetes mellitus. Spanning 40 countries worldwide, it is the world's longest and largest randomized clinical trial of its type in this population, and the first to formally evaluate the effects of insulin on CV outcomes. The trial used a 2x2 factorial design to determine whether using insulin glargine to target fasting normoglycemia (FPG less than or equal to 95mg/dL), and separately omega-3 polyunsaturated fatty acids (PUFA), could reduce cardiovascular morbidity and/or mortality(3). Participants assigned to standard care were treated on the basis of the investigator's best judgment and local guidelines, including lifestyle measures, dietary modifications, metformin, sulfonylureas and other oral anti-diabetic agents.
About Lantus (insulin glargine [rDNA origin] injection)
Prescription Lantus is a long-acting insulin used to treat adults with type 2 diabetes and adults and children (6 years and older) with type 1 diabetes for the control of high blood sugar. It should be taken once a day at the same time each day to lower blood glucose.
Do not use Lantus to treat diabetic ketoacidosis.
Important Safety Information for Lantus
Do not take Lantus if you are allergic to insulin or any of the inactive ingredients in Lantus.
You must test your blood sugar levels while using insulin, such as Lantus. Do not make any changes to your dose or type of insulin without talking to your healthcare provider. Any change of insulin should be made cautiously and only under medical supervision.
Do NOT dilute or mix Lantus with any other insulin or solution. It will not work as intended and you may lose blood sugar control, which could be serious. Lantus must only be used if the solution is clear and colorless with no particles visible. Do not share needles, insulin pens or syringes with others.
The most common side effect of insulin, including Lantus, is low blood sugar (hypoglycemia), which may be serious. Some people may experience symptoms such as shaking, sweating, fast heartbeat, and blurred vision. Severe hypoglycemia may be serious and life threatening. It may cause harm to your heart or brain. Other possible side effects may include injection site reactions, including changes in fat tissue at the injection site, and allergic reactions, including itching and rash. In rare cases, some allergic reactions may be life threatening.
Tell your doctor about other medicines and supplements you are taking because they can change the way insulin works. Before starting Lantus, tell your doctor about all your medical conditions including if you have liver or kidney problems, are pregnant or planning to become pregnant, or are breast-feeding or planning to breast-feed.

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(5).
