STARJEMZA
STARJEMZA (ustekinumab-hmny) is an interleukin-12 and -23 antagonist indicated for the treatment of several chronic inflammatory conditions in both adult and pediatric populations. In adults, it is approved for moderate to severe plaque psoriasis, active psoriatic arthritis, and moderately to severely active Crohn’s disease or ulcerative colitis. The therapy is also indicated for pediatric patients aged 6 years and older with moderate to severe plaque psoriasis or active psoriatic arthritis. For patients with plaque psoriasis, the medication is intended for those who are candidates for systemic therapy or phototherapy.
How STARJEMZA Works
STARJEMZA is a monoclonal antibody that binds specifically to the p40 protein subunit shared by the IL-12 and IL-23 cytokines. By targeting this subunit, the drug prevents these cytokines from interacting with the IL-12Rβ1 cell-surface receptor. This disruption inhibits the signaling and cytokine cascades that drive inflammatory and immune responses, including natural killer cell activation and T-cell differentiation. This mechanism is designed to reduce the chronic inflammation that characterizes diseases such as Crohn’s disease and ulcerative colitis.

STARJEMZA Target & Pathway
ProTarget
A cytokine that promotes Th17 cell development and maintenance. IL-23 is upstream of IL-17 in the inflammatory cascade driving psoriasis and inflammatory bowel disease. Blocking IL-23 provides sustained control of these conditions.
Pharmacists can substitute STARJEMZA for Stelara without calling the prescriber. This is a lower-cost alternative with no clinically meaningful differences.
