Efficacy and safety of ustekinumab in Japanese patients with moderately to severely active Crohn's disease: a subpopulation analysis of phase 3 induction and maintenance studies.

ABSTRACT:

Background/aims

Efficacy and safety of ustekinumab were evaluated in a Japanese subpopulation with moderately to severely active Crohn's disease (CD) in UNITI-1, UNITI-2 and IM-UNITI studies and results were compared with the overall population.

Methods

Overall, patients in UNITI-1 (Japan, n=56; failed response to tumor necrosis factor antagonist) and UNITI-2 (Japan, n=26; failed response to prior conventional therapy) were randomized to placebo or ustekinumab intravenous induction (130 mg or ~6 mg/kg) at week 0. Responders to ustekinumab induction therapy (Japan, n=21) were randomized to placebo or ustekinumab (90 mg, subcutaneous) maintenance (every 12 weeks [q12w] or 8 weeks [q8w]) in IM-UNITI. The primary endpoint was clinical response at week 6 for induction studies and
