Basically, the generic form of a biologic. Each batch of a biologic, even the copies of the molecules within a batch, will vary a bit and the drug is never “identical.” It would be impossible to truly “copy” the product, so there can’t be “generics” of them (drugs which have the exact same formula and structure but are made by different companies than the company that first introduced them). But there can be the equivalent – biologics that are super similar in composition to the original and function at least as well (are non-inferior). These super similar products are called biosimilars and they are often cheaper than the original “brand name” stuff.
