LANN-study: Lantus, Amaryl, Novorapid, Novomix Study
Many diabetics gain weight while on insulin therapy. In this study, we evaluate the efficacy of the combination of glimepiride and short-acting insulin on weight control and glucose control. In this study, 150 diabetics whose diabetic control is inadequate while on maximal oral treatment will be randomized to either the new combination treatment or twice daily injections with a mixture of short- and longacting insulin or once-daily injection with a basal insulin analog. The study will compare glucose control and weight gain during a year after randomisation between the three treatments.

Diabetic patients failing on maximal oral treatment usually switch to twice daily administration of a mixture of short- and longacting insulin. Although this improves glycemic control, it is generally accompanied by a substantial gain in body weight. This may lead to an increase in body fat resulting in a worsening of insulin resistance, leading to an increase in insulin dose needed to maintain glycemic control.
The combination of glimepiride(amaryl) and short-acting insulin (novorapid) is thought to attain glycemic control with a smaller increase in body weight.
In this randomized controlled trial, 150 diabetics failing on maximal oral treatment will be randomized to preprandial use of Novorapid combined with Amaryl at 20.00 hours, twice daily Novomix 30, or once daily Lantus. Metformin will be continued.
In the year after randomisation, patients will be followed for glycemic control, body weight, body composition, recorded number of hypoglycemic events, plasma lipid levels, basal and stimulated C-peptide levels and adverse effects.
