Primary Outcome Measures:
  • Risk of CD-related complications at one-year, measured at the practice level [ Time Frame: 12 months ]
    CD-related complications include (1) CD-related surgeries and non-surgical CD events (such as disease flare, bowel obstruction, and bowel damage events (such as symptomatic bowel obstruction, fistula, abscess and CD related hospitalizations and 2) complications and hospitalizations related to CD medications or procedures.


Secondary Outcome Measures:
  • Risk of CD-related complications at 6 months. [ Time Frame: six months ]
    CD-related complications include (1) CD-related surgeries and non-surgical CD events (such as disease flare, bowel obstruction, and bowel damage events (such as symptomatic bowel obstruction, fistula, abscess and CD related hospitalizations and 2) complications and hospitalizations related to CD medications or procedures.


Other Outcome Measures:
  • Proportion of patients at one year who are in Deep Remission without disease progression [ Time Frame: twelve months ]
    Disease progression is defined as the de novo development of strictures or fistula, the occurrence of an intra-abdominal abscess, or surgery for CD (resection, bypass, stricturoplasty).

Arms Assigned Interventions
Active Comparator: Enhanced Treatment Algorithm
The Enhanced algorithm features the early use of combined antimetabolite/adalimumab therapy, and treatment intensification based on ileocolonoscopic findings. Failure to achieve or sustain Deep Remission, which includes sustained normalization of the imaging studies, will result in treatment intensification, according to the steps outlined in the algorithm, irrespective of symptoms.

Other Name: Adalimumab
Conventional Step-care Algorithm
Step-care algorithm that specifies treatment escalation solely on the basis of symptoms quantified using the Harvey Bradshaw Index (HBI).
Other: Conventional Step-care Algorithm
Step-care algorithm that specifies treatment escalation solely on the basis of symptoms quantified using the Harvey Bradshaw Score.

Detailed Description:

Crohn's disease (CD) is a chronic inflammatory disorder of the gastrointestinal tract. During disease exacerbations, pharmacological or surgical intervention is usually needed to re-establish remission. Ideally, strategies should be employed to maintain patients in long-term remission while minimizing exposure to corticosteroids and reduce therapy-related toxicity.

Nevertheless, in reality many patients with CD do not receive effective therapy and their disease often remains active, leading to uncontrolled inflammation and complications from either the underlying disease or corticosteroids.
