Nivolumab producer?

Who makes nivolumab (the drug name) and which companies produce it?

Nivolumab is an oncology monoclonal antibody sold under brand names that can vary by country. It was originally developed by Bristol Myers Squibb (BMS) and is marketed as Opdivo in many markets.

Is nivolumab only made by Bristol Myers Squibb?

In practice, manufacturing can involve multiple contract manufacturers and regional marketing entities even when the product is branded by the original innovator. If you mean “who is the marketing authorization holder/sponsor in a specific country,” that can differ by jurisdiction.

What should I search for to find the specific producer in your country?

Tell me your country (or the product label you have, such as Opdivo) and I can narrow down the “producer” meaning you want—typically either:
- the company that markets/sponsors the product, or
- the manufacturing sites/contract manufacturers.

If you meant “patent/producers” for biosimilar or competition
