Summary
Brief summary (as posted)
This study (UNITI-1) will compare the effects (both positive and negative) of an initial treatment with ustekinumab to placebo over 8 weeks, in patients with moderately to severely active Crohn's disease who have either failed or could not tolerate at least one TNF-antagonist medications in the past (specifically, infliximab, adalimumab, or certolizumab pegol).

Inclusion Criteria: * Have Crohn's disease of at least 3 months' duration with colitis, ileitis, or ileocolitis, confirmed at some time in the past by radiography, histology, or endoscopy * Have active Crohn's disease, defined as a baseline Crohn's Disease Activity Index (CDAI) score of \>= 220 and \<= 450 * Have received infliximab, adalimumab, or certolizumab pegol at a dose approved for the treatment of Crohn disease and did not respond initially (ie, primary nonresponse) * Or responded initially but then lost response with continued therapy (ie, secondary nonresponse) * Or were intolerant to the medication * Have screening laboratory test results within protocol-specified parameters. Exclusion Criteria: * Patients who have had any kind of bowel resection within 6 months * Are pregnant or planning pregnancy (both men and women) while enrolled in the study or for 20 weeks after receiving study agent * Patients who have received infliximab, adalimumab or certolizumab pegol \< = 8 weeks before the first administration of study drug * Patients with certain complications of Crohn's disease that would make it hard to assess response to study drug * Patients with a history of or ongoing chronic or recurrent infectious disease * Patients who have previously received a biologic agent targeting IL-12 or IL-23, including but not limited to ustekinumab (CNTO 1275) or briakinumab (ABT-874)
