Brief Summary

The primary objective of this study was to demonstrate that tight control of disease activity, using stringent criteria based on Crohn's disease activity Index (CDAI), biomarkers (high sensitivity C-reactive protein \[hs-CRP\] and fecal calprotectin), and corticosteroid use, improves the rate of mucosal healing 48 weeks after randomization compared with management using less stringent criteria based only on CDAI and corticosteroid use.

Conditions

Crohn's Disease

Outcome Measures

Primary Outcomes (1)

• Percentage of Participants With Mucosal Healing and No Deep Ulcerations

  Percentage of participants with mucosal healing (defined as Crohn's disease endoscopy Index of severity \[CDEIS\] \< 4) and no deep ulcerations on ileocolonoscopy (defined as the absence of all deep ulcerations in all segments explored in CDEIS) at 48 weeks after randomization (48 weeks after the 1st Key visit). The ileocolonoscopies were evaluated by the site. CDEIS is an index for determining the severity of Crohn's disease. The CDEIS considers deep ulcerations, superficial ulcerations, ulcerated and non-ulcerated surface, and the presence of ulcerated/non-ulcerated stenosis evaluated in 5 pre-defined segments of the colon (ileum, ascending colon, transverse colon, descending colon and sigmoid loop, and rectum). The score ranges from 0 to 44 where higher scores indicate more severe endoscopic activity. Participants with missing data 48 weeks after Randomization were counted as non-responders.

Tight Control Management

EXPERIMENTAL

Participants randomized to receive management of disease activity using criteria based on Crohn's Disease Activity Index (CDAI), high sensitivity C-reactive protein (hs-CRP), fecal calprotectin, and corticosteroid use. Participants received customized therapy that could include prednisone, adalimumab, and azathioprine. Participants who randomized at Week 9 meeting success criteria started with no therapy; participants who randomized prior to Week 9 or who randomized at Week 9 but did not meet the success criteria began treatment with adalimumab. Therapy was escalated according to pre-specified tight control criteria: At Key Visit 1 the success criteria were CDAI \< 150, hs-CRP, \< 5 mg/L, fecal calprotectin \< 250 μg/g, and absence of prednisone use. At Key Visits 3, 4, and 5 (every 12 weeks after Key visit 1), the criteria were CDAI \< 150, hs-CRP \< 5 mg/L, fecal calprotectin \< 250 μg/g, and absence of prednisone during the preceding week.

Biological: Adalimumab; Drug: Prednisone; Drug: Azathioprine

Clinically Driven Management

ACTIVE COMPARATOR

Participants randomized to receive management of disease activity using criteria based on Crohn's Disease Activity Index (CDAI) and corticosteroid use. Participants received customized therapy that could include prednisone, adalimumab, and azathioprine. Participants who randomized at Week 9 meeting success criteria started with no therapy; participants who randomized prior to Week 9 or who randomized at Week 9 but did not meet the success criteria began treatment with adalimumab. Therapy was escalated according to pre-specified failure criteria using less stringent criteria: At Key Visit 1 the criteria for management of disease activity were a CDAI decrease ≥ 70 (CR-70) compared to Baseline or CDAI \< 200 at 1 week prior to the visit. At Key Visits 3, 4, and 5 (every 12 weeks after Key visit 1), the criteria for a change in treatment were a CDAI decrease of ≥ 100 (CR-100) compared to Baseline or CDAI \< 200, and absence of prednisone during the preceding week.

Biological: Adalimumab; Drug: Prednisone; Drug: Azathioprine

Interventions

Adalimumab BIOLOGICAL

If adalimumab was initiated, it was administered subcutaneously as a 160 mg induction dose the first week, followed by 80 mg 2 weeks later, followed by 40 mg every other week as a maintenance dose. The dose of adalimumab was increased from 40 mg eow to 40 mg every week in participants with an inadequate response and de-escalated to 40 mg eow in participants who met success criteria.

Also known as: ABT-D2E7, Humira

Clinically Driven Management; Tight Control Management

Prednisone DRUG

The suggested regimen for participants initiating prednisone consisted of a maximum dose of prednisone 40 mg/day for 2 weeks, followed by a fixed taper for 6 weeks.

Clinically Driven Management; Tight Control Management

Azathioprine DRUG

Participants with normal thiopurine methyltransferase (TPMT) enzyme activity could receive oral azathioprine 2.5 mg/kg/day. In participants with intermediate TPMT enzyme activity azathioprine was initiated at a dose of 1.25 mg/kg/day. The dose of azathioprine was adjusted according to abnormalities of white blood cell (WBC) count, platelet count, liver function tests (LFTs; i.e. alanine transaminase \[ALT\], aspartate transaminase \[AST\], alkaline phosphatase), lipase, blood urea nitrogen (BUN), and serum creatinine.

Eligibility Criteria

• Age: 18 Years - 75 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Diagnosis of ileal, colonic (including rectal), or ileocolonic Crohn's disease (CD) confirmed using imaging technology or endoscopy not more than 6 years prior to Baseline.
• CDAI score of greater than or equal to 220 and less than or equal to 450 at the Baseline visit in participants not receiving prednisone or equivalent at Baseline. CDAI score of greater than or equal to 200 and less than or equal to 450 at the Baseline visit if the participant is receiving prednisone less than or equal to 20 mg or equivalent for at least 7 days before Baseline. CDAI score of greater than 150 and less than or equal to 450 at the Baseline visit if the participant is receiving prednisone higher than 20 mg or equivalent for greater than or equal to 7 days before Baseline
• Participant or his/her legal representative have voluntarily signed and dated an informed consent approved by and compliant with the requirements of this study protocol which has been approved by an Institutional Review Board (IRB)/Independent Ethics Committee (IEC).
• Adequate cardiac, renal and hepatic function as determined by the Principal Investigator and demonstrated by Screening laboratory evaluations, questionnaires and physical examination results that do not indicate an abnormal clinical condition which would place the participant at undue risk and thus preclude participation in the study.
• Participant must be able to self-inject and orally administer study medication or have a designee or Healthcare Professional who can assist

You may not qualify if:

• Previous or current biologic use for Crohn's disease or participation in a biologic study
• Previous or current use of immunomodulators (e.g., methotrexate, azathioprine, 6-mercaptopurine, JAK inhibitor, alpha-integrin) for Crohn's disease or participation in a Crohn's disease study with immunomodulator(s). Current use of immunomodulators for non-Crohn's disease at Baseline.
• Greater than two previous courses of corticosteroid (systemic corticosteroid) or budesonide) for Crohn's Disease. A course is defined as 1) total duration for burst and taper ≥ 4 weeks and 2) prednisone or equivalent ≥ 40 mg (or budesonide ≥ 9 mg) for at least 2 weeks.
• Participants with a poorly controlled medical condition such as: uncontrolled diabetes with documented history of recurrent infections, unstable ischemic heart disease, moderate to severe congestive heart failure (New York Heart Association \[NYHA\] class III or IV), recent cerebrovascular accident and any other condition which, in the opinion of the Investigator or the sponsor, would put the participant at risk by participation in the protocol
• Participants with positive C. difficile stool assay at Screening.
