OC-007 A Multicenter, Double-Blind, Placebo (PBO)-Controlled Ph3 Study of Ustekinumab (UST), A’Human MAB to IL-12/23P40, IN PTS with Moderately-Severely Active Crohn’s Disease (CD) Who are Naïve or not Refractory to anti-TNFΑ: UNITI-2: Abstract OC-007 Table 1

Abstract

Introduction In the Ph2b CERTIFI study, a single intravenous (IV) UST induction dose was effective & safe in CD pts previously failing anti-TNFs, 1 but efficacy in pts only failing conventional therapy is unknown. We evaluated 2 IV UST induction dose regimens in a CD population not refractory to anti-TNFs. Methods Pts with moderate-severely active CD (CDAI 220–450) who failed conventional therapy but were not refractory to anti-TNFs were randomised 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 (reduction in CDAI score of ≥100 pts). At Wk8, pts transitioned to IM-UNITI maintenance study or had safety follow-up through Wk20. Results Of 628 pts randomised, median disease duration was 6.4 yrs; baseline (BL) mean CDAI was 303; 39% & 35% were receiving steroids & immunomodulators, respectively at BL; 69% were naive to anti-TNFs. At Wk6, 55.5% & 51.7% in ~6 mg/kg & 130 mg UST grps were in clinical response vs 28.7% PBO (p Conclusion IV UST induced clinical response & remission in pts with moderate-severe CD not previously failing anti-TNFs & was well-tolerated through induction.
