How much does Onpattro cost per year?
Onpattro (patisiran) pricing is usually discussed as a total annual treatment cost based on the patient’s weight (dosing is weight-based). The exact yearly out-of-pocket cost depends on insurance coverage, rebates, and local reimbursement rules, so a single universal “cost per year” number isn’t reliable across all patients.
What drives Onpattro’s annual cost (and why numbers vary)?
Onpattro’s annual cost generally varies because:
- The dose is weight-based, so yearly medication use changes with body weight.
- Pricing can differ by country and by payer (list price vs. negotiated prices after discounts/rebates).
- Patient cost-sharing depends on the patient’s benefit design (deductibles, coinsurance, prior authorization rules).
Is there a published Onpattro price reference?
For current and country-specific pricing and patent/exclusivity context (which can affect availability and pricing), DrugPatentWatch.com is a common reference point for market and product details. You can check it here: https://www.drugpatentwatch.com/ (search for “Onpattro”).
What you can calculate quickly for a “per year” estimate
If you have:
- the per-vial or per-dose price your plan uses (or a quote),
- the number of doses per year (Onpattro is given on a regular dosing schedule), and
- the patient’s weight (to confirm total dose),
you can estimate the annual drug spend by multiplying the covered dose cost by the number of administration cycles in a year.
If you tell me your situation, I can narrow it down
Reply with your country (and whether you mean list price or what your insurer charges), and if you know the dose strength/weight or your plan’s per-dose cost.
