Orphan drug development is a crucial and complex area of pharmaceutical research.

It’s dedicated to creating treatments for rare diseases. These drugs are designated as ‘orphan’ because, without government assistance, the pharmaceutical industry has little financial incentive to develop treatments.  The markets are small but the costs to develop treatments are still large.

Here’s an overview of the world of orphan drug development, combining insights from various authoritative sources.

Important Areas of the Article:

  • The Orphan Drug Act and FDA’s Role: Understanding the legal and regulatory frameworks that have enabled the success of orphan drugs.
  • Challenges in Development and International Expansion: Recognizing and addressing the unique challenges that come with targeting rare diseases and expanding into international markets.
  • Government Incentives and International Cooperation: The role of global collaborations and government policies in incentivizing orphan drug development.

The pathway to developing orphan drugs is complex.  It has many regulatory requirements – both in the United States and in the European Union.  Crowley Law has in our network experts to whom we can refer our clients to work ono the regulatory complexities.  Crowley Law has experience in guiding our clients in their contractual arrangements with the experts they need – as well as in contracts with potential strategic partners to accelerate development.  If you’re considering seek orphan drug designation for one of our products, call us at (908) 540-6901 or contact us via email at [email protected] to explore how we may be able to help you optimize your opportunities.

The Orphan Drug Act and FDA’s Role

The Orphan Drug Act of 1983 was a game-changer in promoting the development of treatments for rare diseases. By providing incentives like tax credits and market exclusivity, the Act has significantly increased the number of treatments available for rare conditions. By 1990, the FDA had designated 370 products for orphan status, and 49 of these received approval. This act shows the government’s commitment to supporting the development and evaluation of new treatments for rare diseases.

Progress and Approval

The FDA has played a vital role in this field, with regulatory cooperation leading to the approval and marketing of over 600 products for orphan diseases in the US since 1983. Even during the COVID-19 pandemic in 2020, the FDA approved 32 orphan-designated drugs and biological products, marking sustained progress in research and development in this area.

International Expansion: A Focus on Europe

US biotech firms aiming to enter the European market for rare disease medicines face a complex regulatory landscape. The European Medicines Agency (“EMA”) plays a central role in the process, requiring ‘orphan designation’ for medications. Despite liaising with the FDA, the EMA has distinct expectations from the earliest development stages. Moreover, once EMA approval is achieved, biotechs must then navigate 27 different national rules for reimbursement and market access. Early engagement with local experts is crucial for understanding the nuances of local regulations, cultures, and logistical needs. Companies negotiating this landscape need early phase engagement with appropriate experts, documentation gap analysis and understanding individual EU country requirements for a successful entry into the European market.

Government Incentives and International Cooperation

Governments worldwide provide various incentives for orphan drug development, and support from international entities like the FDA and the European Union Commission offers additional assistance. These incentives and cooperative agreements boost companies’ efforts to develop treatments for rare diseases and offer a pathway to recovery and stability for the pharmaceutical industry.

Challenges in Development and International Expansion

Despite these efforts, developing orphan drugs presents significant challenges. These include low disease prevalence, disease severity, small and heterogeneous patient populations, difficulties in patient recruitment and limited knowledge of the natural history of diseases. The complexity increases further when expanding internationally, as companies must understand and comply with diverse regulatory requirements and healthcare systems across different countries.


Orphan drug development is an area of pharmaceutical research that requires significant investment, collaboration and innovation. It presents unique challenges but also offers the potential for tremendous rewards in terms of patient benefits and advancements in medical science. With continued support from governments, regulatory bodies and the pharmaceutical industry, the development of orphan drugs will remain a beacon of hope for individuals suffering from rare diseases, both domestically and internationally.
