Question · Q4 2025
Adi Jayaraman, on behalf of Cory Kasimov, asked about BridgeBio's perspective on the competitive landscape for infigratinib in achondroplasia, following the Phase III data, specifically against CNP pathway therapies and other FGFR3-targeted programs.
Answer
Justin To, CEO of Skeletal Dysplasias, asserted that infigratinib's balance of efficacy (+2.1 cm/year, first and only statistically significant proportionality improvement, normalized HV) and safety (no change in phosphate, no FGFR1/2 toxicity) positions it as best-in-class. He highlighted the known issues with CNP class therapies (vasodilation) and other FGFR3 inhibitors (VEGFR3 liabilities, spermatogenesis, impaired wound healing) as competitive disadvantages.
