Title: A Phase 3, Randomized, Double-blind, Placebo-controlled, Parallel-group, Multicenter Study to Evaluate the Safety and Efficacy of Ustekinumab Induction Therapy in Subjects With Moderately to Severely Active Crohn's Disease (UNITI-2)
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.


Options:
A: 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)
B: Inclusion Criteria:

* Patients who received study agent at the start of study CNTO1275CRD3001 or CNTO1275CRD3002 and completed the Week 8 visit. Exclusion Criteria:
* Patients who underwent a Crohn's disease-related surgery since the start of induction study CNTO1275CRD3001 or CNTO1275CRD3002
* Patients who started a protocol prohibited medication since the start of studies CNTO1275CRD3001 and CNTO1275CRD3002
* Patients with protocol-specified changes to their concomitant medications due to Crohn's disease (due to lack of efficacy) since the start of studies CNTO1275CRD3001 and CNTO1275CRD3002
C: Inclusion Criteria:

* Plaque-type psoriasis diagnosed \>= 6 months prior
* Plaque-type psoriasis covering at least 10% of total body surface areas
* Psoriasis area-and-severity index score of \>=12 at screening and baseline

* Women of childbearing potential and all men must agree to use adequate birth control measures throughout the trials and for 12 months following the last injection of study agent
* Have no history of latent or active tuberculosis (TB)

Exclusion Criteria:

* Currently have nonplaque forms of psoriasis or drug-induced psoriasis
* Women who are pregnant or nursing, or men and women planning pregnancy while enrolled in the study
* Patients who have used any therapeutic agent targeted at reducing IL-12 or IL-23
* Patients who have had a Bacillus Calmette-Guerin (BCG) vaccination within the previous 12 months prior to screening
* Patients who have a history of chronic or recurrent infectious disease or who have or have had a serious infection requiring hospitalization or intravenous antibiotics within the previous 2 months prior to screening
* Patients who have or ever have had a nontuberculous mycobacterial infection or opportunistic infection
* Patients known to be infected with human immunodeficiency virus (HIV), hepatitis B, or hepatitis C
* Patients who have current signs or symptoms of severe, progressive, or uncontrolled renal, hepatic, hematological, gastrointestinal, endocrine, pulmonary, cardiac, neurologic, cerebral, or psychiatric disease
* Patients with a malignancy or who have a history of malignancy (with the exception of certain skin cancers and pre-invasive cervical cancer)
* Patients participating in another trial using an investigational agent or procedure
* Systemic immunosuppressants within 4 weeks of the first administration of study agent
D: 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 Disease Activity Index (CDAI) score of \>= 220 and \<= 450, with confirmation of active inflammation
* Has failed conventional therapy as demonstrated by having received corticosteroids and/or immunomodulators(ie, AZA, MTX, or 6-MP) at adequate therapeutic doses OR Have a history of failure to respond to or tolerate an adequate course of corticosteroids and/or immunomodulators (ie, AZA, MTX, or 6-MP) at adequate therapeutic doses OR Is corticosteroid dependent or has had a history of corticosteroid dependency AND Has not previously demonstrated failure of or intolerance to 1 or more TNF-antagonist therapies (ie, infliximab, adalimumab, or certolizumab pegol) per study criteria
* 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)
