Effectiveness and Safety of Spondylitis Related to Inflammatory Bowel Disease

Study Overview
=================
Brief Summary
-----------------
Adalimumab is an antibody treatment that targets and neutralizes a molecule produced in the body that is associated with inflammation, tumor necrosis factor (TNF). This molecule is an important factor in causing the inflammation seen in people with a form of inflammatory spinal arthritis called spondylitis as well as inflammation in the bowel called Crohn's disease. Spondylitis and Crohn's disease tend to go together and this study will assess to what degree this treatment is effective for those patients that have both disorders at the same time.

Detailed Description
-----------------
The primary objective of the present study is to assess the efficacy of adalimumab in ameliorating the signs and symptoms of spondyloarthritis associated with CD. Although AS patients with IBD were recruited in phase III trials of anti-TNF therapy and shown to respond to treatment, this has not been established in a cohort of patients with exclusive enteropathic spondyloarthritis. Evaluation of such a cohort will address several important issues: Firstly, it will answer the question of whether or not patients with enteropathic spondyloarthritis respond to treatment with adalimumab. Secondly, since patients with IBD represent a cohort at high risk of developing spondyloarthritis, this approach will allow the study of the efficacy of adalimumab in patients with pre-radiographic inflammatory back pain as determined by clinical, laboratory, and radiological outcomes. In particular, the use of MRI as an outcome measure will be explored. In addition, this will allow the further evaluation of diagnostic criteria for pre-radiographic AS. Thirdly, the efficacy of adalimumab in treating IBD associated with SpA has not been previously determined. It has been assumed that the response should be the same as that observed in idiopathic disease. However, it is important to note that the bowel disease related to spondyloarthritis has different genetic associations from idiopathic disease and may have a different underlying pathophysiology. Several biomarkers have been shown to reflect response to anti-TNF therapies in spondyloarthritis e.g. MMP3 and VEGF. However, other surrogates of disease, such as bowel permeability, have yet to be examined.

Exclusion criteria Patient has current diagnosis of colitis other than Crohn's disease Patient has symptomatic known strictures Surgical bowel resections within the past 6 months or is planning any resection at any time point while enrolled in the study Ostomy or ileoanal pouch Short bowel syndrome as determined by the investigator Patient has received prior treatment with intravenous immunoglobulin or any investigational agents within four weeks of Baseline, or five half-lives of the product, whichever was longer Patient has been previously treated with total lymphoid irradiation or anti-CD4 or CAMPATH 1H monoclonal antibodies resulting in persistent CD4 lymphopenia (CD4 lymphocytes < 500/mm3) Patient was previously exposed to a biologic TNF-inhibitor Patient has a history of cancer or lymphoproliferative disease other than: Successfully and completely treated Cervical dysplasia, with no recurrence within the last five years Has a history of uncontrolled diabetes, unstable ischemic heart disease, congestive heart failure, New York Heart Association (NYHA) III, IV, recent stroke (within three months), chronic leg ulcer and any other condition (e.g., indwelling urinary catheter) which, in the opinion of the Investigator, would put the subject at risk by participation in the protocol or who would make the subject unsuitable for the study Positive serology for hepatitis B indicating acute or chronic infection Subject is known to have immune deficiency, history of human immunodeficiency virus (HIV) or is immunocompromised Persistent or recurrent or severe infections requiring hospitalization or treatment with intra-venous (IV) antibiotics within 30 days, or oral antibiotics within 14 days, prior to Baseline Female subjects who are pregnant or breastfeeding Has a history of an allergic reaction or significant sensitivity to constituents of adalimumab Has a history of clinically significant drug or alcohol abuse in the last year Previous diagnosis or signs of central nervous system demyelinating diseases (e.g., optic neuritis, visual disturbance, gait disorder/ataxia, facial paresis, apraxia) Patient has a history of active tuberculosis (TB), histoplasmosis or listeriosis, or other currently active infections suggestive of significant or profound immunosuppression, such as Pneumocystis carinii, aspergillosis or other systemic infections Patient has latent TB (positive PPD skin test) or has other risk factors for the activation of latent TB, e.g. previous exposure to TB, and has not initiated TB prophylaxis prior to the first adalimumab treatment. In either case, the Principal Investigator (sponsor) must be contacted before initiating the study treatment (see Section 5.6.4, Screening for Latent Tuberculosis) Subjects will be excluded if the CXR is found to have changes suggestive of old healed tuberculous lesion (e.g. calcified nodule, fibrotic scar, apical or basilar pleural thickening etc.) Patient has any condition that would prevent participation or completion in this study, including language limitation or possibility that the patient will not be available for the complete study period Patient, in the opinion of the principal investigator, is unlikely to comply with the study protocol or is unsuitable for any other reason.
