Patients Continuing On Sanofi's Lantus® Had Lower Blood Sugar Levels Than Those who Switched to Insulin Detemir -- Real World Outcome Study of Patients with Type 2 Diabetes Presented at American Diabetes Association 74th Scientific Sessions --
BRIDGEWATER, N.J., June 14, 2014 /PRNewswire/ -- Sanofi US announced today results from a real world outcome study of type 2 diabetes (T2D) patients that show switching from Lantus® (insulin glargine [rDNA origin] injection) to insulin detemir demonstrated higher average blood sugar levels (A1C) and lower A1C reduction over a span of 12 months compared to maintaining patients on Lantus. Alternatively, switching patients from insulin detemir to Lantus resulted in a significantly lower A1C compared to maintaining patients on insulin detemir. The study findings were presented at the 74th Scientific Sessions of the American Diabetes Association in San Francisco, Calif.
"The results of this real world study demonstrate variable patient outcomes when switching between basal insulin analogs," said Philip Levin, MD, Co-Director, Model Clinical Research, Greater Baltimore Medical Center, Baltimore, MD, and lead author of the study. "It is important to understand that every patient is different and healthcare professionals need to determine the best treatment approach based on individual needs."
This was a retrospective study (using an electronic medical records database) of two cohorts of adult T2D patients who had hemoglobin A1C (A1C) and weight measures at baseline that were examined between 2006 and 2012. Overall, 13,942 patients were included (female 54%, mean baseline age 58 year, average A1C 8.7%). Cohort 1 was switched to insulin detemir (DET-S) from insulin glargine or continued on insulin glargine (GLA-C) and Cohort 2 was switched to insulin glargine (GLA-S) from insulin detemir or continued on insulin detemir (DET-S).
At one year follow up, in Cohort 1, compared with GLA-C patients, DET-S patients were significantly less persistent with treatment (52.5% vs 61.4%; P < 0.0001), had a significantly higher A1C (8.5% vs. 8.2%, P < 0.0001), experienced significantly less A1C reduction (-0.24% vs. -0.46%, P<0.0001) and a significantly lower proportion of patients achieved A1C <7% (21.0% vs. 26.1%, P<0.0001) and A1C <8% (45.7% vs. 53.2%, P<0.0001) despite a significantly higher proportion of DET-S patients using rapid acting insulin (57.7% vs. 52.5%, P<0.0001); there were no significant differences in hypoglycemia rate (DET-S: 2.1% vs. GLA-C: 2.1%, P=0.8894) or weight gain (DET-S: -0.35 lbs. vs. GLA-C: 0.21 lbs., P=0.3480) between the groups.
In contrast, at one year follow up, in Cohort 2, compared with DET-C patients, GLA-S patients had a significantly lower A1C (GLA-S: 8.1% vs. DET-C: 8.3%, P=0.0213) and a similar A1C reduction (GLA-S: -0.6% vs. DET-C: -0.5%, P=0.0703); the proportions of patients achieving A1C <7% (GLA-S: 25.1% vs. DET-C: 23.6%, P=0.3929), A1C <8% (GLA-S: 54.8% vs. DET-C: 51.3%, P=0.0794), and hypoglycemia rates (GLA-S: 2.3% vs. DET-C: 1.7%, P=0.2314) were similar between groups; GLA-S patients had significantly greater weight gain than DET-C (GLA-S: 3.2 lbs. vs. DET-C: 0.07 lbs., P<0.001).
"Sanofi is committed to helping the 26 million people in the U.S. who are living with diabetes through our portfolio of innovative, integrated and personalized offerings," said Andrew Purcell, Vice President, Head of U.S. Diabetes Patient Centered Unit, Sanofi US. "This study reinforces the importance of evaluating potential patient outcomes when there might be a change in therapy."
Clinical data also needs to be considered when making treatment decisions as there are some limitations to real world outcomes data.
Abstract: Therapeutically Exchangeable? A Real-World Outcome Study of Switching Between Basal Insulin Analogs Among T2DM Patients (Levin et al.) [Abstract No. 915-P, Poster Presentation on Saturday, June 14, 11:30 a.m. to 1:30 p.m. PDT].
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 patients (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 (insulin glargine [rDNA origin] injection)
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.
Tell your doctor about other medicines, especially ones called TZDs (thiazolidinediones), 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 heart failure or other heart problems, liver or kidney problems, are pregnant or planning to become pregnant, or are breast-feeding or planning to breast-feed. If you have heart failure, it may get worse while you take TZDs with Lantus.
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 swelling, weight gain, 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.
