IRDiRC releases Drug Repurposing Guidebook

The International Rare Diseases Research Consortium (IRDiRC) has published an article in Nature Reviews Drug Discovery presenting their new Drug Repurposing Guidebook (DRG). This resource, which follows the Orphan Drug Development Guidebook (ODDG) launched in 2020, serves as a guide for undertaking drug repurposing projects for rare diseases.
Drug repurposing refers to the process of developing an existing marketed drug outside the scope of its original indication, with the ultimate goal of obtaining approval for a new indication. It is a powerful strategy for the development of novel rare disease treatments, and has great potential to help fulfil the large volume of unmet medical need currently faced by the community. However, there are a number of challenges which are unique to drug repurposing. IRDiRC’s DRG aims to help developers overcome these challenges by describing the available tools and initiatives for repurposing, and how they can be applied most effectively. This includes a checklist with considerations to help initiate repurposing projects, an interactive roadmap, and an activity chart highlighting the key activities for each development phase.
The DRG’s utility was tested using three simulated development programmes, and it can support a wide group of stakeholders including academics, clinicians, small and medium-sized enterprises, and patient groups. By providing developers with a better understanding of the available tools to facilitate repurposing, the Guidebook will hopefully lead to more efficient, successful repurposing of drugs for use in rare diseases.
