Rare diseases and orphan drugs, difficulties and statistics
Language version: EN PL
Rare diseases affect only or as much as 6 - 8% of humanity. They are very rare, but they do exist and people suffer from them.
In Poland disease is defined as a rare when for 10,000 people up to 5 of them become ill. If you take into account the number of people in Poland (almost 38 million), the rare disease is affected from 2.3 to 3 million people. Taking into account the voivodships, there may be up to 150,000 sick people in each.
Difficulty in such diseases is based on the diagnosis and treatment of patients. About 6 thousand rare diseases are diagnosed (there can be up to 8 thousands of them!) and the doctor does not meet with enough patients every day to easily and quickly recognize symptoms indicating a given bankruptcy, as it is the case with more common diseases.
The difficulty of therapy lies in the access to medicines, the price of their preparation and their low sales, which gives a small profit to pharmaceutical companies that will not invest in a product whose sale will not cover the costs of research and will not generate income. All these problems result from the small number of patients.
Orphan drugs - this is the name of medicinal products for rare diseases - are subject to the Regulation of the European Union, the European Parliament and the Council No. 141/2000 of 16 December 1999 on orphan medicinal products. The European Medicines Agency – EMA - consists, among others to make it easier for pharmaceutical companies to develop and authorize medicines for rare diseases.
Sponsors / Pharmaceutical companies that want to conduct research on an orphan drug can take advantage of a number of incentives offered to them by the EMA which supports the development of the drug, the registration procedure and giving orphan products the privilege of exclusive trading on the market for a period of 10 years*.
These incentives are aimed at increasing the amount of research on orphan drugs and lowering their prices.
