Detaljeret beskrivelse

This is a multicenter, randomized study of IL-12p40 (CNTO 1275), hereafter referred to as ustekinumab, in 2 populations of participants with moderately to severely active Crohn's disease of at least 6 weeks duration. A total of approximately 120 volunteers will participate in this study in Canada, Belgium, and the United States. Two separate groups of participants (Population 1 and Population 2) will be evaluated. The primary population of participants (Population 1) will consist of approximately 100 participants with Crohn's disease despite treatment with standard Crohn's disease medications (includes agents to decrease intestinal inflammation such as 5-ASA medications such as PENTASA, ASACOL), corticosteroids such as prednisone and/or other drugs known to suppress the immune system called immunomodulators such as azathioprine, 6-mercaptopurine, methotrexate, infliximab or adalimumab [marketed under the trade name of HUMMIRA]). Participants in Population 1 will be randomly assigned (assigned by chance, like "flipping a coin") to double-blind treatment (participants and study staff will not know the identity of the treatments) with ustekinumab and placebo (inactive substance) in 1 of 4 treatment groups as follows: (1) 4 weeks of treatment with ustekinumab 90 mg followed by 4 weeks of treatment with placebo injected subcutaneously (SC, under the skin), (II) 4 weeks of placebo followed by 4 weeks of ustekinumab 90 mg injected SC, (III) 1 intravenous (IV, in the vein) infusion of ustekinumab 4.5 mg/kg followed by 1 IV infusion of placebo, and (IV) 1 IV infusion of placebo followed by 1 IV infusion of ustekinumab 4.5 mg/kg. Population 2 consists of approximately 20 participants who failed to respond to previous therapy with infliximab (trade name REMICADE), a type of antibody that decreases inflammation in patients with moderate to severe Crohn's disease). All participants in Population 2 will receive open-label (un-blinded) treatment with ustekinumab 4.5 mg/kg administered SC for 4 weeks or as one IV infusion. Placebo will not be given to participants in Population 2. The duration of the study for each participant is 28 weeks (not including a screening period of up to 2 weeks) with participants returning at Week 54 to have blood samples collected to assess the concentration of ustekinumab and antibodies to ustekinumab. Adverse events (side-effects) as a measure of safety and tolerability and results from routine laboratory tests will be monitored and reported throughout the study from the time that informed consent is documented up to 3 days after the final blood sample collection at Week 54. Note: doses of ustekinumab used in the study were adjusted by a factor of 0.9 to be consistent with the corrected absorptivity constant for ustekinumab. Therefore, ustekinumab doses of 100 mg and 5 mg/kg previously stated in the study protocol have been restated as 90 mg and 4.5 mg/kg, respectively. No change was made to the amount of ustekinumab given to participants in this study.

Tidsramme
Number of Participants in Population 1 With a Clinical Response at Week 8
Tidsramme: Week 8
The table below provides the number of participants in Population 1 with a clinical response at Week 8 defined as a reduction from baseline in the CDAI (Crohn's disease activity index) score of >= 25% and >= 70 points at Week 8. A reduction in CDAI score correlates with improvement in the severity of illness. The CDAI is derived as a weighted sum of 8 different Crohn's disease related variables: extra-intestinal manifestations, abdominal mass, weight, hematocrit, total number of liquid stools (or bags emptied for participants with a stoma), abdominal pain/cramping, use of antidiarrheal drug(s) and/or opiates, and general well being. The primary endpoint analysis was based on the comparison between the combined SC and IV Placebo and combined SC and IV ustekinumab treatment groups in Population 1.
