Model description

Adult and paediatric olipudase alfa ERT model for acid sphingomyelinase deficiency.

What can be done with this model

  • Residual ASM activity and sphingomyelin burden
  • Olipudase alfa PK, tissue uptake and lysosomal delivery
  • Lyso‑SM, ceramide, spleen, liver, DLCO and platelet endpoints
  • Adult-to-paediatric dose-bridging and regimen optimisation

Free/open layer
