Less Glycemic Variability, Better Patient Reported Outcomes with Lantus[R] and Apidra[R] Regimen vs. Premix Analog Insulin.

- Study Findings Presented at American Diabetes Association's 70th Annual Scientific Sessions -

PARIS, June 26 /PRNewswire-FirstCall/ -- Sanofi-aventis (EURONEXT: SAN and NYSE: SNY) announced today results of a study which demonstrated that patients using Lantus[R] (insulin glargine [rDNA origin] injection) once-daily and Apidra[R] (insulin glulisine [rDNA origin] injection) before meals reported improved patient reported outcomes and decreased glycemic variability versus premix analog insulin. Two abstracts from this study were highlighted at the American Diabetes Association's 70th Annual Scientific Sessions (ADA).

People following a basal-bolus insulin regimen use separate injections of a basal insulin and a mealtime insulin. This regimen is designed to address hyperglycemia before it happens by providing adequate insulin to cover fasting and prandial insulin needs. A premix insulin regimen combines prandial insulin analogs and the intermediate-acting insulin, NPH, in one injection. The results of this study demonstrated that patients using a basal-bolus regimen, with Lantus[R] and Apidra[R], reported improved outcomes and quality of life.

"These results indicate that patients treated with a basal-bolus insulin regimen consisting of Lantus[R] and Apidra[R] demonstrate an improved quality of life and patient reported outcomes compared to those treated with premix analog insulin," said Donald Simonson, MD, MPH, ScD of the Endocrinology, Diabetes and Hypertension Division of Brigham and Women's Hospital in Boston, Massachusetts and principal investigator of the study.

About study results

In this multicenter, randomized clinical trial conducted in 52 US centers, 388 insulin treated patients (82 Type 1 diabetes, 306 Type 2 diabetes) were randomized to open-label daily Lantus[R] and premeal Apidra[R] (Lantus[R] and Apidra[R]; n=192) or twice-daily premix 75/25 or 70/30 (premix; n=196) for 12 weeks (Period 1) and crossed to an alternate arm for 12 weeks (Period 2) while being titrated to A1C of <7%. The baseline A1C was 7.8+/-0.7%.

The study is highlighted at ADA in two separate abstracts.

1. Patient Satisfaction, Quality of Life and Glycemic Variability in Type 1 and 2 Diabetes: A Cross-over Trial of Insulin Glargine + Glulisine versus Premix Analog Insulin

Abstract Number 2163-PO demonstrated that more patients treated with Lantus[R] and Apidra[R] achieved greater satisfaction, improved quality of life, better glycemic control and less variability, without increased risk of hypoglycemia or other adverse events versus premix analog insulin. Outcomes showed:

* Reductions in mean A1C with Lantus[R] and Apidra[R] (-0.53 +/- 0.10%) versus premix (-0.2 +/- 0.10%) for Period 1 (p<0.0001) and -0.25 +/- 0.10 % versus +0.10 +/- 0.10% for Period 2 (p<0.0001), respectively.

* 55% of Lantus[R] and Apidra[R] patients reached A1C<7% versus 31% for premix (p<0.0001) for Period 1, with no differences in serious adverse events (5.4 versus 4.9%, p=NS) or hypoglycemia.

* Patient Satisfaction Net Benefit scale (0-100) improved from 51.1 to 60.5 +/- 1.2 for Lantus[R] and Apidra[R], but worsened to 45.4 +/- 1.2 for premix (p<0.0001).

* Overall quality of life was improved significantly for the Lantus[R] and Apidra[R] regimen versus premix (p<0.001).

2. Decreased Glycemic Variability during Insulin Therapy Improves Patient-Centered Outcomes in Type 1 and Type 2 Diabetes

Abstract Number 0001-LB demonstrated that glycemic variability, as estimated by continuous glucose monitoring (CGMS), was lower for the Lantus[R] and Apidra[R] group than the premix group, and exhibited more favorable patient reported satisfaction and perceived health. Patient satisfaction consisted of glycemic effectiveness, advocacy, preference and general satisfaction; perceived health consisted of vitality, general health and sleep. Outcomes showed:

* Continuous glucose monitoring standard deviations were lower in the Lantus[R] and Apidra[R] group compared to premix analog insulin by 12.2 +/- 2.6 mg/dl and, as such, more favorable patient satisfaction (p<0.0001) and perceived health (p<0.01) was exhibited.

* The statistical model estimated that, for each 10 mg/dl decrease in continuous glucose monitoring standard deviation, patient satisfaction significantly improved by 2.2 +/- 0.5 (p<0.001), Patient Satisfaction Net Benefit scale (0-100).

* The data analysis indicated that while patient satisfaction worsened for each year of insulin use by 2.3 +/- 0.9 (p<0.01), it increased by 6.1 +/- 1.2 for each percent decrease in A1C (p<0.001).

About Diabetes

Diabetes is a chronic, widespread condition in which the body does not produce or properly use insulin, the hormone needed to transport glucose (sugar) from the blood into the cells of the body for energy. More than 230 million people worldwide are living with the disease and this number is expected to rise to a staggering 350 million within 20 years. It is estimated that nearly 24 million Americans have diabetes, including an estimated 5.7 million who remain undiagnosed. At the same time, approximately 40 percent of those diagnosed are not achieving the blood sugar control target of A1C <7 percent recommended by the ADA. The A1C test measures average blood glucose levels over the past two-to-three-month period.
