Japan Orphan Drugs Industry Trends and Drivers:
The Japan market is growing rapidly for orphan drugs on account of the increasing government support toward drugs for rare diseases. The Japanese Ministry of Health, Labour and Welfare has adopted favorable measures for the production of orphan drugs such as a fast-track approval procedure, longer market exclusivity and financial support to pharmaceutical companies that develop orphan drugs. In addition, access to approved orphan drugs by patients is made possible by the country’s universal healthcare system combined with national health insurance, resulting in a solid and predictable market for them. Orphan drugs for oncology and hematology remain the largest disease areas, with pioneering biologics for the treatment of previously untreatable diseases, including rare cancer, blood diseases, and genetic diseases. The success of blockbuster orphan drugs such as Revlimid, Rituxan, Opdivo, and Keytruda attests to the commercial potential and clinical significance of this therapeutic arena.
Orphan drug R&D is being spurred on by technological advances in biotechnology, genomics and precision medicine that are also expanding treatment options. An increased understanding of the genetic basis of rare diseases is leading to the development of targeted biologic therapies by pharmaceutical companies, which are more effective and have better safety profiles. Japanese pharmaceutical companies as well as the global pharmaceutical companies are placing large R&D investments in rare diseases, knowing that there is an unmet medical need as well as a very attractive market. Rare disease patient advocacy groups have an increasingly important role in promoting awareness, funding research, and aiding in clinical trial recruitment for studies in rare diseases. The distribution channels are also changing, with hospital pharmacies still the primary point of supply for orphan drugs, as these treatments require that they be administered in a closely supervised medical setting. With the market for orphan drugs expected to grow significantly in multiple therapeutic areas and stages of development as Japan’s aging population drives up the number of patients with varied rare diseases and as the detection of these diseases at an early stage becomes easier, it is a market that will see high growth.
