Stelara
- Brands Stelara
- Product Code: Stelara
Stelara is a fully human immunoglobulin G1κ monoclonal antibody that binds specifically to the p40 subunit shared by IL-12 and IL-23, preventing their interaction with the IL-12Rβ1 receptor. This action inhibits downstream inflammatory pathways—particularly Th1 and Th17 cytokine responses—thereby reducing pathological inflammation.
Indications
Stelara is indicated for:
-
Plaque psoriasis in adults (and in some regions, children);
-
Psoriatic arthritis, alone or with methotrexate;
-
Moderately to severely active Crohn’s disease;
-
Moderately to severely active ulcerative colitis.
For patients with Crohn’s or ulcerative colitis, it is used when they have failed conventional or biologic therapies.
