A Multicenter, Randomized, Double-Blind Study to Evaluate Higher Versus Standard Adalimumab Dosing Regimens for Induction and Maintenance Therapy in Subjects with Moderately to Severely Active Crohn's Disease and Evidence of Mucosal Ulceration.

1. Males and females >= 18 and <= 75 years of age at Baseline.
2. Diagnosis of colonic, ileocolonic, or ileal Crohn's disease for >= 3 months prior to Baseline and
confirmed by endoscopy during the Screening period or endoscopy performed within 45 days before
Baseline, with exclusion of current infection, dysplasia, and/or malignancy. Appropriate documentation of biopsy results consistent with the diagnosis of CD, in the assessment of the
Investigator, must be available.
3. Simplified Endoscopic Score for Crohn's Disease (SES-CD) >= 6, excluding the presence of
narrowing component, or SES-CD >= 4, excluding the presence of narrowing component, for patients
with disease limited to the ileum, on a screening endoscopy or endoscopy performed within 45 days
before Baseline, confirmed by a central reader.
4. Crohn's Disease Activity Index (CDAI) >= 220 and <= 450 at Baseline despite concurrent or prior
treatment with a full and adequate course, in the opinion of the Investigator, of at least one of the
following (oral corticosteroids and/or immunosuppressants or both as defined below):
* Subject taking oral corticosteroids, excluding budesonide:
o Oral corticosteroid dose must be <= 40 mg/day (prednisone or equivalent);
* For subjects with a dose > 10 and <= 40 mg/day, dose has been stable for at least 7 days
prior to Baseline and the duration of the current steroid course has been at least 14 days
prior to Baseline.
* For subjects with a dose <= 10 mg/day, dose has been stable for at least 10 days prior to
Baseline and the duration of the current steroid course has been at least 14 days prior to
Baseline.
* Subject taking oral budesonide:
o Dose must not exceed 9 mg/day;
* For subjects with a dose >= 6 mg/day, dose has been stable for at least 7 days prior to
Baseline and the duration of the current steroid course has been at least 14 days prior
to Baseline;
* For subjects with a dose < 6 mg/day, dose has been stable for at least 10 days prior to
Baseline and the duration of the current steroid course has been at least 14 days prior to Baseline;
or,
* At least a consecutive 42-day course of azathioprine, 6-MP or injectable MTX prior to Baseline,
with a stable dose for at least 28 days prior to Baseline of azathioprine >= 1.5 mg/kg/day or 6-MP >= 1 mg/kg/day (rounded to the nearest available tablet or half tablet formulation or a documented 6-TGN level of at least 230 pmol/8 × 108 RBC to clarify a therapeutic level was achived on the current dosing regimen) or MTX >= 15 mg/week (subcutaneous [SC]/Intramuscular [IM]), or a dose that is the highest tolerated by the subject (e.g., due to leukopenia, elevated liver enzymes, nausea) during that time.
Note: If a subject is taking both an oral corticosteroid and an immunosuppressant listed above,
BOTH of the drugs need to meet the above criteria. Oral MTX use is allowed during the study
(at a stable dose for 28 days prior to Baseline) however current or prior use of oral MTX is not
sufficient for inclusion into the study.
or,
* Concurrent therapy with oral corticosteroids or immunosuppressants (azathioprine, 6-MP or
SC/IM MTX) is not required for subjects not currently taking these medications who were previously treated during the past 1 year and have confirmed documentation of failure to respond, or were previously treated during the past 5 years and have confirmed documentation indicating lack of tolerability.
5. Subject may be included if they have previously experienced a benefit from infliximab and
discontinued its use due to a subsequent loss of response (judged by the Investigator to have
responded to infliximab in the past and subsequently experienced an overall lack of improvement or
worsening of CD-related symptoms) or intolerance (in the opinion of the Investigator therapy was
discontinued as a result of a significant acute or delayed infusion/administration reaction to the
medication) to the agent. Confirmed documentation indicating loss of response or lack of tolerability
will be required.
6. Subject has a negative TB Screening Assessment (including a PPD test or QuantiFERON TB Gold test [or equivalent]) and negative chest x-ray (CXR - PA and lateral view) at Screening. If the
subject has evidence of a latent TB infection; the subject must initiate and complete a minimum of
2 weeks of an ongoing TB prophylaxis or have documented completion of a full course of anti-TB
prophylaxis, prior to Baseline.
7. If female, subject is either not of childbearing potential, defined as postmenopausal for at least 1 year
or surgically sterile (bilateral tubal ligation, bilateral oophorectomy and/or hysterectomy) or is of
childbearing potential and is practicing an approved method of birth control throughout the study and
for 150 days after last dose of study drug. Examples of approved methods of birth control which
result in a low failure rate (i.e., less than 1% per year) when used consistently are (see local informed consent for more detail):
* Implants, injectables, some intrauterine devices (IUDs), intrauterine hormone releasing system
(IUS)
* Sexual abstinence (when in line with preferred and usual lifestyle of the subject)
* Vasectomized partner
* Hormonal contraceptives for at least 90 days prior to study drug administration.
Note: low-dose progestin-only oral contraceptives such as norethindrone 0.35 mg and lynestenol
0.5 mg are not considered adequate.
8. Subject must be able and willing to give written informed consent and to comply with the requirements of this study protocol.
9. Subject is judged to be in otherwise good health as determined by the Principal Investigator based upon the results of medical history, laboratory profile, physical examination, CXR, and a 12-lead electrocardiogram (ECG) performed during Screening.
