Brief Summary:
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).

Condition or disease Intervention/treatment Phase
Crohn's Disease IBD Colitis Inflammatory Bowel Disease Drug: Group 2 ustekinumab 130 mg Drug: Group 3: ustekinumab approximately 6 mg/kg Drug: Group 1: Placebo Phase 3

Detailed Description:
This study (CNTO1275CRD3001 or "UNITI-1") 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 who previously did not respond to, lost response to, or could not tolerate TNF-antagonist medications (specifically, infliximab, adalimumab or certolizumab pegol). 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 703 patients. 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'' [NCT01369355]), 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 (either placebo or ustekinumab) at the first (week 0) visit when they enter the study.There are 3 treatment groups: 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).

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of Participants With Clinical Response at Week 6 [ Time Frame: Baseline and Week 6 ]
    Clinical response at Week 6 was defined as a reduction from baseline in the Crohn's Disease Activity Index score of greater than or equal (>=) 100 points (in general, CDAI score ranges from 0 to approximately 600; higher score indicates higher disease activities). Participants with a baseline CDAI score of > = 220 to less than or equal (< =) 248 were considered to be in clinical response if a CDAI score of less than (<) 150 was attained. A CDAI score of less than 150 indicates clinical remission. A decrease in CDAI score over time indicates improvement in disease activity.


Secondary Outcome Measures :
  1. Number of Participants in Clinical Remission at Week 8 [ Time Frame: Baseline and Week 8 ]
    Clinical remission is defined as a CDAI score of less than (<) 150 points at Week 8.

  2. Number of Participants in Clinical Response at Week 8 [ Time Frame: Baseline and Week 8 ]
    Clinical response at Week 8 was defined as a reduction from baseline in the Crohn's Disease Activity Index (CDAI) score of greater than or equal (>=) 100 points. Participants with a baseline CDAI score of > = 220 to less than or equal (< =) 248 were considered to be in clinical response if a CDAI score of less than (<) 150 was attained. A CDAI score of less than 150 indicates clinical remission. A decrease in CDAI score over time indicates improvement in disease activity.

  3. Number of Participants With Crohn's Disease Activity Index (CDAI) 70-point Response at Week 6 [ Time Frame: Baseline and Week 6 ]
    70-point response is defined as at least 70 points reduction in CDAI score. The CDAI score is used to quantify the symptoms of participants with Crohn's Disease. A decrease in CDAI over time indicates improvement in disease activity.

  4. Number of Participants With CDAI 70-point Response at Week 3 [ Time Frame: Baseline and Week 3 ]
    70-point response is defined as at least 70 points reduction in CDAI score. The CDAI score is used to quantify the symptoms of participants with Crohn's Disease. A decrease in CDAI over time indicates improvement in disease activity.
