Question · Q3 2025
Maxwell Skor asked about physician perspectives on initiating Setrusumab for osteogenesis imperfecta, specifically whether they would prioritize younger patients or those with more advanced disease, based on KOL interactions.
Answer
Howard Horn, Chief Financial Officer, indicated that initial adoption would likely prioritize patients with the most severe disease (Type IIIs and IVs), often younger, but noted that adult patients with Type I OI also experience significant bone dysfunction. He anticipated use across the spectrum, with younger, more severe patients gaining immediate access, drawing parallels to Crysvita's growing adult use.
