The Short-Term Cost-Effectiveness of a Fixed-Ratio Combination of Insulin Degludec and Aspart: A Cost of Control Analysis in Australia and India



The real-world ARISE study demonstrated initiation of fixed-ratio combination insulin degludec and aspart (IDegAsp) led to improvements in people achieving key glycemic control targets compared with prior therapies in Australia and India. This study evaluated the short-term cost-effectiveness of IDegAsp in these countries, in terms of the cost per patient achieving these targets.


A model was developed to evaluate the cost of control (treatment costs divided by the proportion of patients achieving each target) of IDegAsp versus prior therapies received in ARISE for 2 endpoints: glycated hemoglobin (HbA1c) 7.0%, and HbA1c less than a predefined individual treatment target. Costs, expressed from a healthcare payer perspective, were captured in 2022 Australian dollars (AUD) and 2022 Indian rupees (INR).


The number of patients needed to treat to bring one to endpoints of HbA1c 7.0% and less than an individualized target, respectively, in Australia and INR 211 142 and INR 537 490 lower with IDegAsp compared with prior therapies in India.


IDegAsp was estimated to be cost-effective versus prior therapies when considering an individualized HbA1c target in Australia, and when considering an individualized HbA1c target and HbA1c 7.0% in India.
