Stelara (ustekinumab) - J&J
Early but not serial ustekinumab concentration measurements are associated with clinical outcomes in Crohn's disease and ulcerative colitis: the Stockholm Ustekinumab study (STOCUSTE). (PubMed, Eur J Gastroenterol Hepatol) - Sep 22, 2026 - "In this study, an early (≤3 months) UST concentration was associated with remission, whereas concentrations measured at later time points did not differ between remission and nonremission. In this real-world cohort serial monitoring beyond 3 months showed poor correlation with clinical outcomes."
