Maybe you disagree, but I don't think infliximab or even rituximab is close to the same level of importance as things like penicillin, Thorazine, misoprostol, or oral rehydration therapy. Insulin is, and it's technically a biological, but it was pre-01962.

I listed the three antivirals I think were revolutionary rather than evolutionary (all of which were post-01962), and I did list lovastatin, which was the first statin available, and widely applicable, and therefore the revolutionary one.
