A General Strategic Review on Rare Diseases & Orphan Drugs
Joan Chambers
Senior Strategic Advisor
Rare diseases are generally defined as diseases that affect fewer than 200,000 people in the United States. Because rare diseases touch so few people, pharmaceutical companies traditionally did not pursue drug treatment for them. In addition, only a few types of rare diseases are tracked in the United States. That makes it more difficult to know exactly how many rare diseases exist and how many people have them.1 Treating these diseases has its own unique challenges, said Scott Schliebner, vice president of scientific affairs – rare diseases for PRA Health Sciences. Schliebner, considered an industry expert on this topic, is also a well-recognized speaker about rare diseases.
