Oral semaglutide versus injectable glucagon-like peptide-1 receptor agonists: a cost of control analysis.

Aims: The efficacy and safety of oral semaglutide, the first glucagon-like peptide-1 (GLP-1) receptor agonist developed for oral administration for the treatment of type 2 diabetes, was evaluated in the PIONEER clinical trial program, and a recently published network meta-analysis allowed comparison with further injectable GLP-1 receptor agonists. The present study aimed to assess the short-term cost- effectiveness of oral semaglutide 14 mg versus subcutaneous once-weekly dulaglutide 1.5 mg, once-weekly exenatide 2 mg, twice-daily exenatide 10 µg, once-daily liraglutide 1.8 mg, once-daily lixisenatide 20 µg, and once-weekly semaglutide 1 mg, in terms of the cost per patient achieving glycated hemoglobin (HbA1c) targets (cost of control).Materials and methods: Cost of control was calculated by dividing the annual treatment costs associated with an intervention by the proportion of patients achieving the treatment target with an intervention, with outcomes calculated for targets of HbA1c ≤6.5% and HbA1c <7.0% for all included GLP-1 receptor agonists. Annual treatment costs were accounted in 2019 United States dollars (USD), based on 2019 wholesale acquisition cost.Results: For the treatment target of HbA1c ≤6.5%, once-weekly semaglutide 1 mg and oral semaglutide 14 mg were associated with the lowest costs of control, at USD 15,430 and USD 17,383 per patient achieving target, respectively. Similarly, the cost of control was lowest with once-weekly semaglutide 1 mg at USD 12,627 per patient achieving target, followed by oral semaglutide 14 mg at USD 13,493 per patient achieving target for the target of HbA1c <7.0%. All other interventions were associated with higher cost of control values for both targets.Conclusions: Oral semaglutide 14 mg is likely to be cost-effective versus dulaglutide, exenatide (once weekly and twice daily), liraglutide, and lixisenatide in terms of bringing people with type 2 diabetes to glycemic control targets of HbA1c ≤6.5% and HbA1c <7.0% in the US.

Evaluating the short-term cost-effectiveness of liraglutide versus lixisenatide in patients with type 2 diabetes in the United States.

AIMS: Bringing patients with type 2 diabetes to recommended glycated hemoglobin (HbA1c) treatment targets can reduce the risk of developing diabetes-related complications. The aim of the present analysis was to evaluate the short-term cost-effectiveness of once-daily liraglutide 1.8 mg vs once-daily lixisenatide 20 µg as an add-on to metformin for treatment of type 2 diabetes in the US by assessing the cost per patient achieving HbA1c-focused and composite treatment targets. MATERIALS AND METHODS: Percentages of patients achieving recommended targets were obtained from the LIRA-LIXI trial, which compared the efficacy and safety of once-daily liraglutide 1.8 mg and once-daily lixisenatide 20 µg as an add-on to metformin in patients with type 2 diabetes failing to achieve glycemic control with metformin. Annual costs were estimated from a healthcare payer perspective. An economic model was developed to evaluate the annual cost per patient achieving target (cost of control) with liraglutide 1.8 mg vs lixisenatide 20 µg for five end-points. RESULTS: Annual treatment costs were higher with liraglutide 1.8 mg than lixisenatide 20 µg, but this was offset by greater clinical efficacy, and the cost of control was lower with liraglutide 1.8 mg than lixisenatide 20 µg for all five end-points. The annual cost of control was USD 3,850, USD 11,404, USD 3,807, USD 4,299, and USD 6,901 lower for liraglutide 1.8 mg than lixisenatide 20 µg for targets of HbA1c < 7.0%, HbA1c ≤ 6.5%, HbA1c < 7.0% and no weight gain, HbA1c < 7.0% with no weight gain and no confirmed hypoglycemia, and HbA1c < 7.0% with no weight gain and systolic blood pressure <140 mmHg, respectively. CONCLUSIONS: Once-daily liraglutide 1.8 mg was associated with greater clinical efficacy than once-daily lixisenatide 20 µg, which resulted in a lower annual cost of control for HbA1c-focused and composite treatment targets.
