Long-Acting Insulin Analogues In Type 2 Diabetes: Advantage Over Human Insulin Not Proven
Long-term effects of insulin detemir are not assessable / Evidence base is insufficient, even if unpublished data are considered
It has so far not been proven that long-acting insulin analogues (LAIAs) have an advantage over conventional human insulin in the treatment of patients with type 2 diabetes. Even though the results of a 5-year study are available for one of the two LAIAs assessed (insulin glargine), the potential long-term benefits and harms of this drug class have still not been sufficiently investigated. This is the result of the final report published by the Institute for Quality and Efficiency in Health Care (IQWiG) on 19 March 2009.
The final report is part of a comprehensive commission package awarded by the Federal Joint Committee, by means of which key therapy options for people with diabetes are to be assessed. The reports on rapid-acting insulin analogues in diabetes mellitus type 1 and 2 have already been completed.
Only one study lasting longer than 12 months was available
For the assessment of the LAIAs, IQWiG searched for studies that either compared one of the two currently approved LAIAs for the treatment of type 2 diabetes (insulin glargine and insulin detemir) with human insulin, or compared the benefits of the two LAIAs with each other. A precondition for study inclusion was that patients had been randomly allocated to one of the treatment groups and that the treatment period had lasted at least 24 weeks, as the aim of the project was to assess the potential benefits and harms of long-term therapy.
A database search and queries to the manufacturers resulted in the retrieval of a total of 18 studies for inclusion in the evaluation. Of these studies, 15 (glargine: 9; detemir: 6) compared an LAIA with neutral protamine Hagedorn (NPH) insulin, a longer-acting (intermediate-acting) insulin based on human insulin. The other 3 studies compared the two LAIAs with each other. In 11 studies, insulin was used in addition to oral antidiabetics, in 6 studies within the framework of intensified insulin therapy…
