Abstract:

BACKGROUND: Addition of the GLP-1 receptor agonist liraglutide to insulin can reverse insulin-associated weight gain, improve HbA1c and decrease the need for insulin, but is expensive. From a cost perspective, such treatment should be discontinued when it is clear that treatment targets will not be achieved. Our aim was to find the best cost-controlling treatment strategy: the shortest possible trial period needed to discriminate successfully treated patients from those failing to achieve predefined targets of treatment success. METHODS: We used data from the 'Effect of Liraglutide on insulin-associated wEight GAiN in patients with Type 2 diabetes' (ELEGANT) trial, comparing additional liraglutide (n = 47) and standard insulin therapy (n = 24) during 26 weeks, to calculate the costs associated with different trial periods. Treatment success after 26 weeks was defined by having achieved >/= 2 of the following: >/= 4% weight loss, HbA1c </= 53 mmol/mol (7%), and/or discontinuation of insulin. RESULTS: The additional direct costs of adding liraglutide for 26 weeks were euro 699 per patient, or euro 137 per 1 kg weight loss, compared with standard therapy. The best cost-controlling treatment strategy (identifying 21 of 23 responders, treating four non-responders) was to continue treatment in patients showing >/= 3% weight loss or >/= 60% decrease in insulin dose at 8 weeks, with a total cost of euro 246 for this t rial period, saving euro 453 in case of early discontinuation. CONCLUSION: An 8-week trial period of adding liraglutide to insulin in patients with insulin-associated weight gain is an effective cost-controlling treatment strategy if the liraglutide is discontinued in patients not showing an early response regarding weight loss or insulin reduction.
