Prior Authorization (Initial Authorization)

Length of Approval: 12 Month(s)

• Diagnosis of primary immunoglobulin A nephropathy (IgAN)
AND

AND
• Used to slow kidney function decline
AND
• One of the following:
• Patient has been on a minimum 90-day trial of a maximally tolerated dose of one of the following:

OR
• Patient has a contraindication or intolerance to both ACE inhibitors and ARBs
AND
• Medication will not be used in combination with any of the following:
• Angiotensin receptor blockers or angiotensin receptor-neprilysin inhibitor (ARNI) [e.g., Entresto (sacubitril/valsartan)]

End Notes

1. The International IgAN Prediction Tool incorporates clinical information at the time of biopsy and is a valuable resource to quantify risk of progression and inform shared decision-making with patients [2]
