Novo Nordisk’s Rivfloza OK’d for Rare Disease

FDA has approved a Novo Nordisk NDA for Rivfloza (nedosiran) injection, a once-monthly subcutaneous ribonucleic acid interference therapy for lowering urinary oxalate levels in children nine years of age and older and adults with primary hyperoxaluria Type 1 and relatively preserved kidney function. The rare genetic disease causes overproduction of oxalate by the liver that can lead to progressive kidney damage.

Approval was based on data from the pivotal Phase 2 PHYOX 2 clinical trial and interim data from the ongoing phase 3 PHYOX 3 extension study, according to the company. The study met its primary endpoint, showing that patients treated with Rivfloza achieved a marked reduction from baseline in 24 hour-urinary oxalate excretion from Day 90 to Day 180, it says.
