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 74
th 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.
