Clinical Trial Summary

The purpose of this program is to provide participants with access to an investigational drug, nedosiran, for treatment of primary hyperoxaluria type 1 (PH1).

Novo Nordisk may terminate the program at any time for any reason, including if the drug receives regulatory approval and becomes commercially available, or if the drug does not receive regulatory approval. Nedosiran will be given once a month with a thin needle in the thigh or abdomen. The study doctor will ask the participant to come to the clinic monthly.
