Report Overview

Since the enactment of the Orphan Drug Act in 1983, the drug development landscape for rare diseases in the U.S. has changed significantly. The law was enacted to incentivize pharmaceutical companies to concentrate on the development of drugs for rare diseases, i.e., diseases that afflict fewer than 200,000 individuals. Prior to the Act, these diseases had been virtually ignored because of the low economic enticements to firms to develop them. The expenses for developing medications were significant but the patient base was small, creating uncertainty about the monetary returns. The Orphan Drug Act altered this situation by providing a range of incentives, the most significant among which was a seven-year market exclusivity following approval. This assisted in the making of development of treatments for rare diseases economically viable.

More drugs have over the years acquired orphan drug status. To date, hundreds of drugs in development have been assigned such status with the indications ranging from rare tumors to genetic conditions, cardiovascular diseases, and neurologic conditions. The FDA orphan drug designation not only encouraged the development of novel treatments but also has resulted in some unexpected commercial success stories. Those drugs initially designed for limited patient populations now are showing to be profitable products, reversing the opinion that orphan drugs cannot exhibit good market performance.

One of the best examples is Merck's Keytruda (pembrolizumab), an immune checkpoint inhibitor that originally received orphan drug designation in 2012 for malignant melanoma. Since then, Keytruda has had its indications broadened to include various cancers, such as esophageal carcinoma, lymphoma, and lung cancer, among others, many of which are orphan diseases. Although an orphan drug, Keytruda is now amongst the world's best-selling cancer medications, with 2024 revenue of almost U.S.$ 29.4 billion, an astonishing 18% increase over last year. Importantly, more than 60% of this originated from the U.S. alone. This business success demonstrates how orphan drugs, in the long run, can discover larger markets and generate sizeable returns.

Likewise, Gilead's Biktarvy, an HIV drug, was given orphan drug designation and is now one of the company's best-selling drugs. In 2024, it recorded U.S.$ 13.4 billion in sales, up 13% from the previous year. Both drugs underscore how treatments for rare diseases can evolve from specialty therapies into big moneymakers.

The success of these drugs in the market shows that orphan drug development can be both clinically effective and profitable. With appropriate incentives, companies are more likely to invest in the treatment of rare diseases, even if the number of patients is small. The incentives created by the FDA and other regulatory authorities, including the potential for market exclusivity and fast-track review, enable firms to break even on their investment and reap huge profits in the long term. These advantages have motivated numerous firms to enter the orphan drug area, particularly since rare diseases are increasingly being understood as a result of advances in genomics and biotechnology.

In addition, the development of the orphan drug market has contributed to the rise in collaborations between pharmaceutical firms. Collaborations can assist in the division of the cost and the acceleration of the development of new medicines. An example is the partnership between Cadrenal Therapeutics and Abbott, established in March 2025 to aid in the development of tecarfarin, a new oral anticoagulant, in patients with HeartMate 3™ Left Ventricular Assist Devices (LVADs). Tecarfarin, granted orphan drug status, is under investigation in a clinical trial for enhancing anticoagulation benefit in patients with advanced heart failure. This alliance reflects the increased trend of grouping together resources and expertise to make therapies for rare conditions, as the scientific and logistical hurdles associated with orphan drug development can be significant.

In the future, the U.S. market for orphan drugs will continue to grow. The regulatory environment will continue to shift to facilitate orphan drug development, with increasingly streamlined approval procedures and additional incentives to stimulate innovation. As rare diseases are increasingly well understood, and as advances in science offer new means of attacking them, the market for orphan drugs will increasingly be characterized by diversity in the types of diseases being treated. There is also increased awareness that rare diseases tend to have common molecular mechanisms, raising the possibility that treatments applicable across larger groups could be developed.
