Brief summary

This study (UNITI-2) will compare the effects (both positive and negative) of an initial treatment with ustekinumab to a placebo over 8 weeks in patients with moderately to severely active Crohn's disease.

Detailed description

This study (CNTO1275CRD3002 or UNITI-2) examines ustekinumab (an antibody medication that inhibits the inflammatory proteins IL-12 and IL-23) versus a placebo (otherwise identical except without the ustekinumab antibody) given intravenously (by an IV) in adults with moderately to severely active Crohn's disease. Ustekinumab (also known as Stelara) is approved as a treatment for the skin condition of moderate to severe plaque-type psoriasis, but this study will examine if ustekinumab can provide benefit in Crohn's disease and also assess for any risks or side effects. Both the positive and negative outcomes of IV placebo versus two different doses of IV ustekinumab will be tracked and compared over eight weeks, in approximately 612 patients who have previously failed or were intolerant to corticosteroids or immunomodulators (methotrexate, azathioprine, or 6-mercaptopurine) or are dependent on corticosteroid medications. Patients enrolling in this study will be assigned to one of the 3 treatment groups by chance (randomly, like rolling dice), and all will receive a single IV administration of study agent at the first study visit (after the screening period), and then will be asked to return for 3 additional visits through Week 8. Patients who complete this study through the Week 8 visit and remain eligible can enter the maintenance study (CNTO1275CRD3003 or IM-UNITI), where they will receive additional study agent, including the administration of ustekinumab in patients who receive placebo in this study and have not had improvement in their Crohn's disease. Patients who do not enter the CNTO1275CRD3003 study will have a final safety follow-up visit approximately 20 weeks after they received study agent when they entered into this study at the Week 0 visit. .All patients will receive a single intravenous (IV) administration of study drug (placebo or ustekinumab) at the start of the study.There are 3 treatment groups in this study: Group 1: Placebo; Group 2: ustekinumab 130 mg, Group 3: weight-range based ustekinumab doses approximating ustekinumab 6 mg/kg: 260 mg (weight \<= 55 kg), 390 mg (weight \> 55 kg and \<= 85 kg), and 520 mg (weight \> 85 kg).

Participant flow

Recruitment details

A total of 640 participants were randomly assigned to receive study agent. The analyses (efficacy) were based on the 628 participants who were randomized after the study was restarted. However, one additional participant was excluded from efficacy analyses due to misconduct by the investigative site.

Pre-assignment details

In November 2011, due to stability issue with the batch of the IV drug (130 mg Ustekinumab) sponsor temporarily suspended dosing of participants with ustekinumab. Study was restarted with 90 mg/ml on 17 February 2012.
