Interventions

Participants will receive monthly SC doses (3.5 mg/kg, not exceed 170 mg) of nedosiran over 6 months.The maximum injection volume in participants is 0.5 mL
if the participants weight requires an injection volume > 0.5 mL, the total dose will be administered as 2 SC injections. No dose modifications are allowed, except for dose adjustments based upon weig
