Therapeutics for Rare and Neglected Diseases (TRND)
TRND program supports preclinical development of therapeutic candidates intended to treat rare or neglected disorders, with the goal of enabling an Investigational New Drug (IND) application. Learn more.
About TRND
More than 6,500 rare and neglected diseases have been identified, yet only about 250 treatments are available for these conditions. The limited numbers of patients can make gathering information and designing drug studies difficult. As a result, scientists often know little about the symptoms and biology of these conditions. Also, some private companies may find it difficult to justify the cost of developing drugs for such small rare disease markets.
The Therapeutics for Rare and Neglected Diseases (TRND) program is designed to overcome these challenges. Its mission is to encourage and speed the development of new treatments for diseases with high unmet medical needs. TRND stimulates therapeutic development research collaborations among NIH and academic scientists, nonprofit organizations, and pharmaceutical and biotechnology companies working on rare and neglected illnesses. The program provides expertise and resources, working with research partners to move therapeutics through preclinical testing, including plans for clinical trials and submission of an IND application to the U.S. Food and Drug Administration (FDA). These efforts effectively “de-risk” therapeutic candidates and make them more attractive for adoption by outside business partners.
TRND Program Goals
The goal of the TRND program is to encourage and speed the development of new treatments for rare and neglected diseases. The program is designed to advance the entire field of therapeutic development by supporting scientific and technological innovations to improve success rates in the crucial preclinical stage of development.
TRND closes the gap that often exists between a basic research discovery and testing of new drugs in humans. That work includes the optimization and preclinical testing of therapies, with the goal to generate sufficient-quality data to support successful IND applications to the FDA and first-in-human studies in limited situations. Therapeutic clinical candidates that reach this stage should be attractive to biotechnology and pharmaceutical companies to take into clinical development.
