Hereditary transthyretin-mediated (hATTR) amyloidosis: a multisystem, often fatal disease1-3
- Neuropathic pain
- Bilateral carpal tunnel syndrome
- Difficulty walking
- Orthostatic hypotension
- Urinary retention
- Recurrent urinary tract infections
- Sexual dysfunction
- Sweating abnormalities
- Unintentional weight loss
- Conduction abnormalities
- Heart failure
ONPATTRO® (patisiran) does not treat all of the symptoms of hATTR amyloidosis.
hATTR amyloidosis can progress quickly and lead to significant burden4-6
- Inability to walk unaided
- Wheelchair-bound or bedridden
- Impairment in self-care
- Impairment in ability to perform usual activities
- hATTR amyloidosis can lead to premature death in 4.7 yearsa
aMedian survival following diagnosis.
Important Safety Information and Indication
Important Safety Information
Infusion-related reactions (IRRs) have been observed in patients treated with ONPATTRO® (patisiran). 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).
The most common adverse reactions that occurred in patients treated with ONPATTRO were upper respiratory tract infections (29%) and infusion-related reactions (19%).
ONPATTRO is indicated for the treatment of the polyneuropathy of hereditary transthyretin-mediated amyloidosis in adults.
