Genetic PH1 mouse model (AGXT-/-): dose-dependent urinary oxalate reduction (~50% at 3 mg/kg)
“In vivo study in a genetic PH1 mouse model (AGXT-/-) (single dose): Single doses of 0.3, 1 and 3 mg/kg lumasiran resulted in a dose-dependent reduction of urinary oxalate and an increase in urinary glycolate. A single 3 mg/kg dose of lumasiran resulted in a reduction of urinary oxalate by approximately 50%.”
HAO1 target site conserved across mammals; rodent and monkey pharmacologically relevant
“The target site of lumasiran in the HAO1 mRNA is conserved across mammalian species and both rodent and monkey are pharmacologically relevant species.”
FDA: nonclinical data support efficacy in decreasing HAO1 mRNA, GO enzyme and oxalate production
“The nonclinical data support the efficacy of lumasiran to decrease levels of HAO1 mRNA, GO enzyme levels and the production of oxalate, based on the following data:”
