Crohn's Disease Clinical Trial
Official title:
A Randomized, Double-Blind, Placebo-Controlled, Dose-Finding, Safety Study of Two Parallel Dose Levels of Subcutaneously Administered Human Monoclonal Antibody to Interleukin-12 (J695) in Patients With Active Crohn's Disease
This study will examine the safety and effectiveness of an experimental drug called J695 for
treating patients with Crohn's disease-a long-term recurring inflammation of the small and
large intestine. This disease is currently treated with steroids, sulfasalazine
(Azulfidine), 5-ASA drugs (Pentasa, Asacol), immune suppressants, antibiotics, and an
antibody against TNF-alpha. Despite the number and variety of available therapies for
Crohn's disease, many patients do not respond adequately to treatment or they develop severe
side effects from the medicines. Therefore, new treatments must be developed. J695 is an
antibody that is identical to a human antibody but chemically changed so that it can attach
to and eliminate an inflammatory chemical made by the body called interleukin-12 (IL-12).
Animal studies have shown that eliminating IL-12 with an antibody can prevent inflammation
in the gut and can also heal inflammation that has already developed.
Patients 18 years of age and older who have had Crohn's disease for at least 4 months may be
eligible for this study. Candidates will be screened with a medical history and physical
examination, electrocardiogram, chest X-ray, blood and urine tests, stool analysis and
possibly a review of medical records. They will complete a Crohn's Disease Activity Index
Questionnaire for 7 days. Participants will be randomly assigned to one of two treatment
groups, as follows:
Group 1
Patients in this group will receive an injection of either J695 or placebo (a solution that
does not contain any active medicine) under the skin on day 1 of the study, on day 29, and
then weekly for a total of seven injections. After the last injection, patients will be
followed for an additional 18 weeks. They will be monitored periodically throughout the
study with physical examinations, disease activity index scores, and blood and urine tests.
Group 2
Patients in group 2 will receive an injection of J695 or placebo on day 1 of the study and
then weekly for a total of six injections. They will be followed for an additional 18 weeks.
Patients will be monitored as described above for group 1.
Participants may be asked to undergo additional tests as part of a sub-study in this
protocol. These include colonoscopies to examine changes in inflammation in the gut and
blood tests to analyze changes in the cells and body chemicals that affect the inflammation.

INCLUSION CRITERIA All subjects must have a verifiable diagnosis of Crohn's disease of at least 4 months' duration. The diagnosis must be supported by characteristic 1) clinical features (symptomatic or endoscopic) or radiographic findings and 2) histopathologic changes. All subjects must be over age 18. Subjects must be male or female who are surgically sterile (hysterectomy and/or bilateral oophorectomy), have a history of tubal ligation, or are post-menopausal with greater than or equal to 12 months duration of spontaneous amenorrhea. Subjects are eligible if the Crohn's disease is mildly to moderately active based on a Crohn's Disease Activity Index score between 220 and 450 (with a diarrhea rating or abdominal pain rating greater than or equal to 25). If currently receiving any medications for Crohn's disease, subjects may only be on a stable regimen of one or a combination of the following drug doses and durations: Antibiotic therapy greater than or equal to 2 weeks, Corticosteroids (less than or equal to 20 mg Prednisone/d, or Prednisone equivalent) greater than or equal to 4 weeks, 5-ASA/Sulfasalazine greater than or equal to 4 weeks, Azathioprine/6-MP greater than or equal to 8 weeks, (Note: patients receiving azathioprine or 6-MP must have been receiving these medications for greater than or equal to 12 weeks before randomization). Use of prophylactic methods of birth control throughout the study period for male and female subjects who are not surgically sterile or postmenopausal: abstinence or barrier methods for male subjects, use of additional form of contraception (abstinence, barrier or hormal method) for women of child-bearing potential with a history of tubal ligation, and use of two forms of contraception for women of child-bearing potential who had been enrolled in this study prior to knowledge of the developmental toxicity data in monkeys. Women of child-bearing potential (women who are not surgically sterile or postmenopausal) must have a negative serum Beta-hCG to exclude early pregnancy. Subjects must have negative results on stool examination for culture of enteric pathogens (Salmonella, Shigella, Yersinia, Campylobacter, Vibrio, E. coli O157/H7), Clostridia difficile toxin assay, enteric parasites and their ova (including Cryptosporidia). Subjects must have a chest X-ray free of changes consistent with any infections or malignancy. Subjects who cannot meet the above requirements are excluded. Subjects using any of the following medications within the specified time period prior to the first dose of study drug or at any time during the study are excluded: NSAIDs/COX-2 inhibitors/ greater than 500 mg/d aspirin within 24 hours, Corticosteroid enema or 5-ASA enema or suppositories within 7 days, Corticosteroids (greater than 20 mg Prednisone/d or Prednisone equivalent) within 4 weeks, Methotrexate, Cyclosporin, Tacrolimus (FK506), Thalidomide, Etanercept (Enbrel), Mycophenolate mofetil (CellCept), or any biological therapy, Monoclonal antibodies to TNF within 4 months, Any experimental agent within 1 month. Subjects with multiple bowel resections (greater than or equal to 200 cm) AND enteral or parenteral therapy to maintain weight are excluded. Subjects with use of any other investigational agent within 30 days of randomization for this study are excluded. Subjects must not have any of the following abnormalities on an electrocardiogram: QT(c) greater than 0.48 sec, Mobitz type II second or third degree atrioventricular block, left bundle branch block or right bundle branch block with any fascicular block, changes consistent with acute ischemia. Subjects with moderate persistent asthma defined as the presence of one of these features are excluded: Clinical features before treatment: Daily symptoms, exacerbations affect activity and sleep, nighttime asthma symptoms greater than 1 time a week, peak expiratory flow (PEF) or forced expiratory volume (FEV1) greater than 60% to less then 80% of predicted, variability greater than 30%; Daily medication required to maintain control: Daily controller medications (especially for nighttime symptoms): inhaled corticosteroids or long-acting bronchodilators. Subjects with severe persistent asthma defined as the presence of one of the features listed below are excluded: Clinical features before treatment: Continuous symptoms, frequent exacerbations, frequent nighttime asthma symptoms, physical activities limited by asthma symptoms, PEF or FEV(1) less than 60% predicted, variability greater than 30%; Daily medication required to maintain control: Multiple daily controller medications (long-term): high-dose inhaled corticosteroids, long-acting bronchodilators and oral corticosteroids. EXCLUSION CRITERIA Subjects with a history of tuberculosis or BCG vaccination are excluded. Subjects with a diagnosis of ulcerative colitis are excluded.
