What is Onpattro (patisiran), and how does it work?
Onpattro is a treatment for hereditary transthyretin-mediated (hATTR) amyloidosis in people whose condition is driven by a gene mutation that leads to production of abnormal transthyretin (TTR) protein. It uses an RNA interference approach to reduce TTR production in the liver, lowering the amount of amyloid-forming protein available to build up in organs.
Who is Alnylam, and what does it have to do with Onpattro?
Alnylam is the company that developed and markets Onpattro (patisiran). In the supply and commercial sense, Alnylam is the relevant manufacturer/brand owner for Onpattro in the way patients and clinicians usually mean when they ask “Alnylam Onpattro.”
What is Onpattro used for?
Onpattro is used in patients with hATTR amyloidosis. It is typically considered for people with polyneuropathy caused by hATTR amyloidosis, and regulatory labeling depends on the specific patient group and geography.
How is Onpattro given?
Onpattro is administered by infusion (it is not a pill). Dosing schedules and required premedications can vary by label and clinical protocol, but the core point is that treatment is delivered through an infusion setting.
What side effects do patients ask about most?
Common concerns with Onpattro include infusion-related reactions and general treatment tolerability issues associated with infused biologics/therapies. Patients and clinicians also watch for lab and safety signals that may come with long-term therapy for amyloidosis.
How does Onpattro compare with other Alnylam medicines for hATTR?
Alnylam also markets another RNAi therapy for hATTR amyloidosis, which works through the same overall strategy (reducing TTR production), but differs by formulation, route of administration, dosing schedule, and sometimes the specific patient populations covered by labeling. If you tell me the comparison you care about (route, eligibility, or dosing), I can tailor it.
