  Purpose

This study will be a prospective, open label, randomized, comparative study. Comparing the efficacy of adalimumab with immunomodulator therapy (i.e. 6-mercaptopurine, 6-MP), in maintaining remission of post-operative CD patients, with a high risk of disease recurrence.

Patient assessment for efficacy will be conducted through interval endoscopic surveillance at 24 and 52 weeks.

Patients in the adalimumab arm, showing endoscopic remission at 52 weeks of therapy, will be re-randomized to either maintain adalimumab therapy for an additional 52 weeks or conclude therapy. A third endoscopic assessment for these patients will be conducted at 104 weeks.

The investigators expect a substantial increase in both endoscopic, as well as clinical remission rate in patients on adalimumab therapy.

Further study details as provided by Tel-Aviv Sourasky Medical Center:

Primary Outcome Measures:
  • The proportion of patients with endoscopic recurrence at 12 months, as evaluated by the Rutgeerts endoscopic scoring system. [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]
    Primay outcome measure will assess the efficacy of adalimumab, compared to immunomodulator therapy in maintaining mucosal healing after 52 weeks (1 year).


Secondary Outcome Measures:
  • Proportion of patients in clinical remission at 12 months as assessed by the CDAI score. [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]

Estimated Enrollment: 100
Study Start Date: July 2012
Estimated Study Completion Date: July 2016
Estimated Primary Completion Date: July 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Adalimumab Drug: Adalimumab
Subcutaneous adalimumab injections, loading dose of 160 mg and 80 mg on 0 and 2 weeks and maintenance of 40 mg every other week for the duration of the study.
Other Name: Humira
Active Comparator: 6-mercaptopurine Drug: 6 Mercaptopurine

6MP will be administered orally starting at a dose of 6MP of 50mg/day with escalating doses every 1-2 weeks as tolerated, to a target dose of 1-1.5 mg/kg.

Criteria

Inclusion Criteria:

  • 18-70 years old at the time of screening
  • Male or female
  • Firs ileocolonic surgical resection (
  • Evidence of both macroscopic as well an microscopic evidence of Crohn's disease in the resected intestinal segment
  • Patient able to undergo pre randomization screening no earlier then 14 days and no later then 45 days post operatively.
  • Patients may receive anti-TNF-agents (i.g. infliximab or adalimumab)previously
  • Patients may receive corticosteroids, 6MP/AZA, methotrexate, or mesalamine prior to surgery.
  • Antibiotics, or mesalamine, must be discontinued within the screening/baseline 4 week period. Patients on steroids may be enrolled as long as steroids are tapered off.
  • Remission as defined by a CDAI ≤ 150.
  • Women of childbearing potential, and men, must use medically acceptable methods of contraception [surgical sterilization, IUD, hormonal preparations, or double barrier method (e.g. condom or diaphragm, and spermicide)] throughout the study and for a period of 6 months after receiving the last injection.
  • Screening lab results must be within prespecified limits: Hemoglobin ≥ 8.8 g/dl; SGOT/SGPT < 3 X the upper limit of normal; Neutrophil count ≥ 1.0 X 109/L & lymphocyte cont of ≥ 0.5 X 109/L
  • Must have a documented PPD ≤ 5 mm, in patients taking steroids, within the month before randomization, or taking immunomodulators 2 months prior to randomization. Other patients must have documented PPD ≤ 10 mm prior to randomization. PPD must be preformed and documented by an appointed member of the investigatory stuff. Patients must have a normal chest radiograph (both posterior-anterior and lateral views), read by a certified radiologist, within 3 months prior to randomization.
  • Commitment to adhere to study protocol requirements
  • Negative stool cultures for enteric pathogens (Salmonella, Shigella, Campylobacter, Ova & parasites), and negative clostridium difficile toxin assay in stool.
  • Patients are able to self-inject or have a designee or healthcare professional who can inject the study medication at the appropriate intervals.
  • Patient's with long standing (>5Y), as well as recently diagnosed Crohn's disease ,will be eligible if they show radiologic (i.e. CT enterography, MR enterography , small bowel follow through) evidence, as well as laboratory (i.e. CRP, platelets level, fecal calprotectin, ESR ) evidence for an active inflammatory process within a 3 months period prior to the qualifying surgery

Exclusion Criteria:

  • evidence of macroscopic inflammatory disease at the surgical margins or else ware, according to the surgeon
  • Patients who discontinued anti TNF-alpha agents due to loss of efficacy or tolerability issues.
  • Patients with temporary ileostomy.
  • Patients with longstanding quiescent CD undergoing surgery for the treatment of a fibrostenotic lesion, without an active inflammatory disease process in the resected segment.
  • Any of the following medications taken within 3 months prior to randomization: cyclosporine, tacrollimus, mycophenolate mofetil, or other investigational anti-inflammatory agents. Medication targeting the reduction of TNF-alpha (infliximab, golimumab, cetrolizumb pegol, etanercept), natalizumab, or other FDA approved biological agents may be administered up until to index surgery.
  • Patient who have an ongoing active infection within the baseline period: intra-abdominal abscess, enteric infection as determined by stool cultures for bacteria, parasites and clostridium difficile toxin, other serious systemic bacterial infection within 3 months before randomization (e.g. Pneumonia; pyelonephritis; meningitis).
  • Patients with active TB, patients in close contact to individuals with active TB, patients with latent TB whether receiving or not receiving prophylaxis.
