Orencia expiry date?

When does Orencia lose patent protection?
Orencia (abatacept) was patented under US Patent 7,173,432, which expired in 2018. The primary patents covering the drug’s active ingredient and formulation have all expired, removing the legal barrier that once kept competitors out of the market. [1]

What does that mean for patients?
Patent expiry does not automatically bring generics to market because abatacept is a biologic. The U.S. FDA grants 12‑year exclusivity to biologics, meaning the first biologic entrant cannot be approved as a biosimilar until that period lapses. Orencia’s exclusivity period ends in 2028, so true biosimilar competition will not begin until then.

Which companies are working toward a biosimilar?
Several companies, including Sandoz and Pfizer, have filed for approval of abatacept biosimilars. These applications are still pending review, and none has received FDA clearance yet.

Will insurance cover a future generic or biosimilar?
Insurance plans typically cover biosimilars once approved and when they are listed on formularies. Once a biosimilar receives FDA approval and the manufacturer secures a price point competitive with Orencia, insurers are likely to adopt it.

What is the shelf life of the medication itself?
Orencia is supplied as a lyophilized powder that is reconstituted before use. The reconstituted solution has a shelf life of 24 hours when stored at 2–8 °C. The pre‑filled syringes have a shelf life of 5 years when stored in the refrigerator, but the exact expiration date is printed on each vial.

How can I confirm the expiration date on my medication?
Look for the “use by” or “expiration” date printed on the vial or the packaging. If you have a vial that has passed its printed date, do not use it.

What should I do if my prescription is close to its expiration date?
Contact your prescriber or pharmacy. They can prescribe a new supply, and you can use the medication within its shelf life after reconstitution.
