Humira's biosimilars are roughly 20% of the cost of name-brand Humira ($600/mo). It can even be down to 10% of the original cost, or lower, in some shops. You can buy a month's supply for ~75 from an Indian pharam supplier online, for example. The slight kicker is that the biosimilars are not 100% the same (fat) molecule as the original adalimumab.

Insurance companies are starting to say they wont cover name-brand Humira without a strong doctor's note.

Still, the price of the drug went down from being completely unaffordable without insurance to the price of an car payment. It's still expensive, but much better than before. You're not as tied to your company providing good insurance, for example.
