What is a rare disease?

Although the number of patients per disease is small, more than 7,000 rare diseases have been identified worldwide, and the total number of patients is estimated to be 300 million. Although definitions differ from country to country, according to the "Orphan Drug, Orphan Medical Device, and Orphan Regenerative Medicine Product Designation System" based on the Law Concerning Quality, Efficacy, and Safety Assurance of Pharmaceuticals, Medical Devices, etc. (Pharmaceutical Affairs Law), the requirements for designation are that "the number of eligible patients is less than 50,000 in Japan The requirements for designation are: "the number of target patients is less than 50,000 in Japan," "there is a high medical need for the product," and "the product has a high potential for development. In the U.S., the number of patients is less than 200,000, and in Europe, the number of patients per 10,000 population is less than 5. In addition to the small number of patients, the disease is characterized by its high severity and the fact that the mechanism of pathogenesis is unknown, making the development of treatment methods difficult and limiting effective therapies.

That is all.
