OC-005 A Multicenter, Double-Blind, Placebo (PBO)-Controlled Ph3 Study of Ustekinumab (UST), A Human IL-12/23P40 MAB, in Moderate-Severe Crohn’s Disease (CD) Refractory to anti-TNFΑ: UNITI-1

Introduction In a Ph2b study(CERTIFI), 1 UST intravenous(IV) induction followed by subcutaneous(SC) maintenance was effective in moderate-severe CD refractory to anti-TNF therapy. This Ph3 study examined efficacy&safety of IV UST induction in these pts. Methods Pts with moderate-severe CD(CDAI 220–450) who previously failed/were intolerant to ≥1 TNF-antagonist were randomised 1:1:1 at Wk0 to a single dose of IV PBO, UST 130  mg, or weight-based tiered UST dosing ~6 mg/kg. Primary endpoint was clinical response at Wk6(baseline [BL] CDAI score reduced by ≥100); pts with BL CDAI ≥220 to ≤248 were considered in clinical response if CDAI score of Results The 741 randomised pts had history of TNF-antagonist failure, with BL median CDAI = 317, CRP = 9.9 mg/L, and prior disease duration of 10.1 yrs. Of these, 51% had previously failed ≥2 anti-TNFs with 29.1%, 69.4%, and 36.4% of pts, respectively. Clinical response at Wk6 was observed in 33.7%/34.3% of the ~6 mg/kg/130 mg UST grps vs 21.5% on PBO(p = 0.003, p = 0.002, respectively). Clinical remission(CDAI Conclusion In a population of moderate-severe CD pts refractory to ≥1 prior TNF-antagonists, IV UST induced clinical response and remission and was well-tolerated throughout induction, confirming the previous positive induction data from CERTIFI.
