Market Overview

The South Korea interferon alpha-2a biosimilar market consists of the segment that develops, manufactures and distributes biosimilar alternatives to interferon alpha-2a, a recombinant cytokine that is used to treat chronic viral hepatitis, certain cancers as well as immune-related disorders. These alternative products provide a less expensive treatment option while providing a level of safety, quality, and efficacy similar to the originator product. The South Korean market has all the abatement factors for an established and expanding biosimilar market, including favorable government direction to expand biosimilars usage, a highly developed biologics manufacturing infrastructure, and the presence of capable domestic companies, with biosimilar experience outside of South Korea. Demand side dynamics are influenced by the need for affordable biologics in hospitals and clinics in South Korea, particularly by providers dealing with patients with chronic conditions. There are possible restraining factors. Demand will continue to be moderated around limited use of interferons for the treatment of hepatitis C, highly technical manufacturing processes, and strict national and regional identifier comparability and safety recommendations.
