METHODOLOGY: Multiple approaches including assessing utilization and prices of insulins including biosimilars among six Asian countries and comparing the findings especially with other middle-income countries.

RESULTS: Typically, there was increasing use of long-acting insulin analogues among the selected Asian countries. This was especially the case enhanced by biosimilars in Bangladesh, India, and Malaysia reflecting their perceived benefits. However, there was limited use in Pakistan due to issues of affordability similar to a number of African countries. The high use of biosimilars in Bangladesh, India and Malaysia was helped by issues of affordability and local production. The limited use of biosimilars in Japan and Korea reflects limited price reductions and demand-side initiatives similar to a number of European countries.

RESULTS: Typically increasing use of long-acting insulin analogues across Europe including both Western and Central and Eastern European countries reflects perceived patient benefits despite higher prices. However, activities by the originator company to switch patients to more concentrated insulin glargine coupled with lowering prices towards biosimilars have limited biosimilar uptake, with biosimilars not currently launched in a minority of European countries. A number of activities were identified to address this. Enhancing the attractiveness of the biosimilar insulin market is essential to encourage other biosimilar manufacturers to enter the market as more long-acting insulin analogues lose their patents to benefit all key stakeholder groups.
