Hello, smart scientists! What’s up with all these -“umab” suffix medicines I’m seeing popping up all over tv?

I’ve seen the adalimumab Humira commercials for a couple of years know (I think, or maybe 2020 just really has been the longest five years of my life). But lately I’ve seen all kinds of other medicines being advertised that end in the -umab suffix. Is it from a particular chemical formula/compound family, or a particular pharmacological lab? Do they all have similar uses or functions?

-mab is monoclonal antibody, they are manmade molecules that mimic antibodies in your immune system. So they are often drugs that mimic binding proteins for example, to target certain cells in the body to be destroyed.
