    The CRDAC provides the FDA with independent, expert advice and recommendations on marketed and investigational medicines for use in the treatment of cardiovascular and renal disorders. The CRDAC’s vote, while not binding, will be considered by the FDA when making its decision regarding the potential expanded indication for patisiran. The FDA has set an action date of October 8, 2023, under the Prescription Drug User Fee Act.

    Patisiran is the established name for ONPATTRO, which is approved by the FDA for the treatment of the polyneuropathy of hereditary ATTR amyloidosis in adults.

    ONPATTRO Indication and Important Safety Information

    Indication

    ONPATTRO is indicated for the treatment of the polyneuropathy of hereditary transthyretin-mediated amyloidosis in adults.

    Important Safety Information

    Infusion-Related Reactions

    Infusion-related reactions (IRRs) have been observed in patients treated with ONPATTRO. In a controlled clinical study, 19% of ONPATTRO-treated patients experienced IRRs, compared to 9% of placebo-treated patients. The most common symptoms of IRRs with ONPATTRO were flushing, back pain, nausea, abdominal pain, dyspnea, and headache.

    To reduce the risk of IRRs, patients should receive premedication with a corticosteroid, acetaminophen, and antihistamines (H1 and H2 blockers) at least 60 minutes prior to ONPATTRO infusion. Monitor patients during the infusion for signs and symptoms of IRRs. If an IRR occurs, consider slowing or interrupting the infusion and instituting medical management as clinically indicated. If the infusion is interrupted, consider resuming at a slower infusion rate only if symptoms have resolved. In the case of a serious or life-threatening IRR, the infusion should be discontinued and not resumed.

    Reduced Serum Vitamin A Levels and Recommended Supplementation

    ONPATTRO treatment leads to a decrease in serum vitamin A levels. Supplementation at the recommended daily allowance (RDA) of vitamin A is advised for patients taking ONPATTRO. Higher doses than the RDA should not be given to try to achieve normal serum vitamin A levels during treatment with ONPATTRO, as serum levels do not reflect the total vitamin A in the body.

    Patients should be referred to an ophthalmologist if they develop ocular symptoms suggestive of vitamin A deficiency (e.g., night blindness).

    Adverse Reactions

    The most common adverse reactions that occurred in patients treated with ONPATTRO were upper respiratory tract infections (29%) and infusion-related reactions (19%).
