Title: A Multi-Center, Randomized, Double-Blind, Placebo-Controlled Study of the Human Anti-TNF Monoclonal Antibody Adalimumab for the Induction of Clinical Remission in Subjects With Moderate to Severe Crohn's Disease Who Have Lost Response or Are Intolerant to Infliximab
Brief Summary: The goal of this study is to test whether adalimumab can induce clinical remission in subjects with active Crohn's disease who have been initially treated with infliximab and either lost response or discontinued its use as a result of intolerance to the drug.


Options:
A: Inclusion Criteria:

* Males and females between the ages of 18 and 75 who are diagnosed with mild to moderate Crohn's disease (defined by a CDAI \[Crohn's Disease Activity Index\] score of 220 and 450)
* Normal lab parameters
* Are willing to give informed consent
* Have previously used and either were intolerant to or lost response to infliximab

Exclusion Criteria:

* History of certain types of cancer
* Diagnosis of ulcerative colitis
* Pregnant female or breast feeding subjects

* History of listeria, human immunodeficiency virus (HIV), central nervous system demyelinating disease or untreated TB (tuberculosis)
* History of poorly controlled medical conditions
* Specific doses and durations of Crohn's medications
* Subjects that have previously used infliximab and have never clinically responded unless primary non-response was due to a treatment limiting reaction to infliximab
B: Inclusion Criteria:

* Definitive diagnosis of Crohn's disease confirmed (at least 3 months prior to study entry) either by radiological, endoscopic or histological evidence, affecting the terminal ileum (L1), colon (L2) or ileocolon (L3\*. \*Vienna Classification (1998)

* Male and female aged 18 years or above at screening.
* Patients who meet all concomitant medication criteria in the protocol specified table. For all drugs being taken at screening, the patient should be able to remain on a stable dose throughout the duration of the study, although steroids may be tapered starting at Weeks 8 to 12.

Exclusion Criteria:

* Crohn's Disease Related
* Fistula abscess present at screening.
* Stricturing type disease with symptoms or signs of non-inflammatory mechanical obstruction or bowel perforation in last 3 months.
* Short bowel syndrome.
* Functional colostomy or ileostomy (note: patients who have had a temporary stoma in the past, which has been reversed, are eligible to enter the study).
* Positive stool laboratory results for enteric pathogens.
C: Inclusion Criteria:

* Completed double-blind portion of the IM101064 study.
* Rheumatoid arthritis (RA) for greater than 1 year from the time of initial diagnosis
* American College of Rheumatology (ACR) functional class I, II, III
* Subjects currently or previously received an anti-TNF therapy at an approved labeled dose for at least 3 months

Exclusion Criteria:

* Subjects with active vasculitis of a major organ system (except subcutaneous rheumatoid nodules)
* History of cancer within the last 5 years (other than non-melanoma skin cell cancers cured by local resection)
D: Inclusion Criteria:

* adult patients at least 18 years of age with moderate to severe active RA for at least 6 months;
* inadequate response to current anti-rheumatic therapies, including MTX;
* inadequate response or intolerance to treatment with 1 or more anti-TNF therapies within 1 year of entering study;
* on stable MTX for at least 8 weeks before entering study;
* patients of reproductive potential must be using reliable methods of contraception.
