Targeting a Common Link in Otherwise Different Rare Diseases

February 21, 2020


Fibroblast growth factors are a group cell signaling proteins that play a critical role in growth and development. They have been implicated in achondroplasia, the most common genetic form of dwarfism, but these growth factors are also involved in a number of rare cancers. QED Therapeutics, a BridgeBio company, is developing infigratinib, an experimental tyrosine kinase inhibitor that targets multiple fibroblast growth factors, for both achondroplasia and certain forms of bile duct and bladder cancers. We spoke to Susan Moran, CEO of QED Therapeutics, about the company’s experimental tyrosine kinase inhibitor, the role fibroblast growth factors play in seemingly disparate rare diseases, and the challenges of learning to work with very different types of patient communities.
