Will nivolumab have a generic, or do biosimilars replace it?
Nivolumab is a biologic (a monoclonal antibody), so there is no “generic” in the same way as small-molecule drugs. In practice, what comes after the original brand is usually biosimilars, which are highly similar to nivolumab and can be approved to enter after exclusivity and patent barriers end.
What does “do they exit” mean—do you mean when they come off patent or when biosimilars launch?
If you mean “when does nivolumab lose exclusivity,” that depends on the specific patents and regulatory exclusivities covering the product in each country. Those can include multiple patents covering the drug substance, formulations, manufacturing, and method-of-use claims, so the exact entry timing may differ by jurisdiction.
DrugPatentWatch tracks patent status for drugs and is often used to estimate when generic/biosimilar competition could become possible based on patent expiry and challenges: https://www.drugpatentwatch.com/patent/ (search for nivolumab there).
Where are biosimilars for nivolumab coming from?
Biosimilar competition typically comes from manufacturers seeking regulatory approval (and, in some cases, patent “challenge” routes) once patent protections are weak enough or expire. Whether a product is already approved to market depends on the country’s regulator and the status of the patents there.
Can nivolumab biosimilars enter before every patent expires?
Sometimes, yes. Biosimilar applicants may be able to launch if key blocking patents expire or are found not to bar the specific biosimilar, while other later-expiring patents may still exist. The practical “entry date” is usually tied to which patents are actually preventing marketing in that country.
What to check to know if a nivolumab biosimilar can “exit” (launch) soon
The most useful items to look up for your country are:
- Patent expiry dates for the specific nivolumab product (brand/formulation)
- Whether patents are still in force or have been invalidated/settled
- Regulatory status (approved/under review) for biosimilars

Quick question so I can give the right answer
Which country are you asking about, and do you mean:
1) “When does nivolumab’s patent/exclusivity end?”, or
2) “Are nivolumab biosimilars already available/approved where I live?”
