The National Institutes of Health (NIH) has awarded approximately $26 million in grants in the fiscal year 2025 to begin the fifth cycle of funding for the Rare Diseases Clinical Research Network (RDCRN). This national network brings together scientists, clinicians, patients, families, and patient advocates to study a wide range of rare diseases.
Today, the network consists of 21 research consortia, including 10 that are joining the network for the first time, five that were active in the previous cycle and have been awarded a five-year renewal, and six Cycle 4 consortia that are continuing through a one-year extension of their previous award. An additional $5.6 million has been awarded to a separate Data Management and Coordinating Center hosted at Cincinnati Children’s Hospital Medical Center to support these research efforts.
Addressing the Challenges of Rare Diseases
About one in every nine Americans is affected by a rare disease. Of the approximately 10,000 known rare diseases, only around five percent have US Food and Drug Administration (FDA)-approved treatments. To get a drug from discovery to market, it can take as long as 10 to 15 years and cost up to $2.6 billion. And because most rare diseases are genetic, they often affect infants and children.
To advance rare disease research, Congress passed a law in 2002 authorizing several agencies within the NIH to launch the RDCRN. Each of the 21 consortia that make up the network study at least three different rare diseases.
Since its establishment, the RDCRN has supported hundreds of studies at over 300 clinical sites around the world. These efforts have resulted in over 3,000 publications with topics ranging from natural history studies and case reports to practice guidelines and clinical trials of new treatments. Findings from these studies have contributed to the approval of 11 treatments for rare diseases by the FDA.
