Therapeutics Development Network

The Cystic Fibrosis Therapeutics Development Network is the largest CF clinical trials network in the world. We bring together experts from across the country to evaluate the safety and effectiveness of new CF therapies through clinical studies.

The Therapeutics Development Network (TDN) is a collaborative organization composed of specialists in cystic fibrosis clinical research from a variety of disciplines and institutions:

  • A central coordinating center at Seattle Children’s Research Institute supports clinical trial development, management, and analysis.
  • Ninety-one CF Foundation-accredited care centers with demonstrated expertise in clinical research, called CF Therapeutics Development Centers, recruit study participants and conduct clinical trials.
  • A group of laboratories and interpretation centers, called National Resource Centers, specialize in developing and measuring CF clinical trial outcomes.

The Cystic Fibrosis Foundation is the primary source of funding for the TDN. Additional funding for some clinical studies comes from pharmaceutical companies or government agencies such as the National Institutes of Health and U.S. Food and Drug Administration.

Port CF Registry

The CF Foundation Patient Registry collects information on the health status of people with cystic fibrosis who receive care in CF Foundation-accredited care centers and agree to participate in the Registry. This information is used to create CF care guidelines, assist care teams providing care to individuals with CF, and guide quality improvement initiatives at care centers. Researchers also use the Patient Registry to study CF treatments and outcomes and to design CF clinical trials.
