@jeff97 thank you for sharing. So, the letters are a code, like a VIN# on a car, detailing various aspects of its manufacture? I suspected as much but didn’t know.

“mab” is monoclonal antibodies? Does that mean “single or individually cloned”?
I wonder. “Clone.” Is cloning now commonplace? Are biologics a result of cloning?

I had thought the “il” represented Interleukin (made sense to me) but sometimes letters other than i and l still mean Interleukin (IL) though.
For example:
Secukinumab (Cosentyx): Blocks IL-17A.
Ixekizumab (Taltz): Targets IL-17A.
Brodslumab (Siliq): Blocks the IL-17 receptor.
Bimekizumab (Bimzelx): Inhibits both IL-17A and IL-17F.

Your explaination of the “il”representing the target immunomodulators group explains it, and the IL is a subgroup target, with the number 6 or 17 being specific target in the subgroup of the group.

I’m trying to reverse engineer it in my brain.

I know that hamster ovaries cells are used as little factories to manufacture biologics. Humira (adalimumab) is an example.

I thought saralumab was too, but it may have been an assumption.

Continuing to think out loud, sar vs sars, I don’t think sar in sarilumab relates to severe acute respiratory syndrome. I’m thinking out loud again and maybe trying too hard. Maybe it is a scientists initials or lab name abbreviation.

Thanks again.
