Hypochondroplasia (HCH) is a skeletal dysplasia similar to achondroplasia (ACH) but with milder features, that affects particularly the ossification of proximal long bones of arms and legs. Around 70% to 80% of cases of HCH are caused by N540K alterations in the FGFR3 gene. At the recent 6th Annual Achondroplasia & Skeletal Dysplasia Research Conference, researchers from Tyra Biosciences Inc. presented preclinical proof-of-concept data of TYRA-300, an oral FGFR3-selective inhibitor in a model of HCH.
Bridgebio Pharma Inc.’s data from the phase II study with infigratinib in achondroplasia “swings the pendulum of debate sharply in favor” of the firm, competing with Biomarin Pharmaceutical Inc. in the space, Leerink analyst Mani Foroohar said in a report.
