i am pretty sure there is someone on the forum who was (until they approved it) a clinical trial patient. She (I think she) had good results. Yes, a lot like Humira but (I will quote to be accurate)
"Cimzia is the first and only PEGylated anti-TNF (Tumour Necrosis Factor) antibody. Cimzia retains the potency of the original antibody without the possible cytotoxicity mediated by the Fc portion present in conventional anti-TNFs."
I don't really understand pharmaceutically what "PEGylated" means, but I do know it's a different structure than Remicade and Humira. Maybe the person whose had success in the trial can explain?
