About BAT2206 (ustekinumab)

BAT2206 is a proposed biosimilar to Jansen’s Stelara® which is a human monoclonal antibody that inhibits the bioactivity of human IL-12 and IL-23 by preventing shared p40 from binding to the IL-12Rβ1 receptor protein expressed on the surface of immune cells. IL-12 and IL-23 are involved in inflammatory and immune responses, such as natural killer cell activation and CD4+ T-cell differentiation and activation. IL-12 and IL-23 have been implicated as important contributors to the chronic inflammation that is a hallmark of Crohn's disease and ulcerative colitis, among many other autoimmune diseases.  In the EU, Stelara® is currently approved for the treatment of 1) moderate to severe plaque psoriasis in adults and children above the age of 6 years whose condition has not improved with, or who cannot use, other systemic (whole-body) psoriasis treatments, 2) active psoriatic arthritis, alone or combined with methotrexate, in adults, when the condition has not improved enough with other treatments called disease-modifying anti-rheumatic drugs (DMARDs), 3) moderately to severely active Crohn’s disease in adults whose condition has not improved enough with other treatments for Crohn’s disease or who cannot receive such treatments, 4) moderately to severely active ulcerative colitis in adults whose condition has not improved enough with other treatments for ulcerative colitis or who cannot receive such treatments.
