That's one side of the coin. The other is when will any biosimilar actually hit the market?

The "no refrigeration required" screams freeze dried Humira. So that gives rise to the possibility that the Unifill will be a dual chamber (Ezi-mix type) syringe slapped in a Lisa for administration. Improved shelf life and temp stability puts the biosimilars in the shade as they will require refrigeration or ice pack storage for when you are on the move. Not an issue for a freeze dried powder
