Medical Uses
OTULFI (ustekinumab-aauz), from Fresenius Kabi, is a biosimilar to Stelara, indicated for the treatment of moderate to severe plaque psoriasis, active psoriatic arthritis, and moderately to severely active Crohn’s disease and ulcerative colitis in adult patients.
Ustekinumab-aauz is a monoclonal antibody that targets the p40 subunit shared by interleukin-12 (IL-12) and interleukin-23 (IL-23), blocking their interaction with immune cell receptors and reducing the inflammatory cascade underlying these autoimmune conditions.
