About this study
Official title: Prospective, Multicenter, Randomized, Double-Blind, Placebo-Controlled Trial Comparing REMICADE (Infliximab) and Placebo in the Prevention of Recurrence in Crohn's Disease Patients Undergoing Surgical Resection Who Are at Increased Risk of Recurrence
REMICADE (infliximab) is a drug used to treat active Crohn's disease and is being tested in an experiment to see if it may be useful in preventing relapse of Crohn's disease after surgical resection. This study will compare the effects (both good and bad) of REMICADE (infliximab) to those of placebo. Placebo looks like the drug being studied but has no active ingredients.
Read the detailed description
The purpose of this study is to assess the effects of REMICADE (infliximab) in preventing relapse of Crohn's disease after surgical resection. Patients will be assigned to a group that will initially receive either infliximab or placebo. Each patient who is allowed to join the study is put into a group by chance (randomly), like flipping a coin. There is a possibility that patients can receive both the study drug and placebo at different times in the study. If a patient is initially randomized to receive placebo, and their study doctor confirms that they have had a return of active Crohn's Disease symptoms, they can receive infliximab. If a patient is initially randomized to receive infliximab, and their study doctor confirms that they are experiencing symptoms of Crohn's Disease, they may receive an increase in their infliximab dose. Infusions will be administered at Week 0 and then every 8 weeks thereafter through Week 200. The study will use a measure of Crohn's Disease activity that will be evaluated at each visit and at any time the patient has symptoms suggestive of their disease getting worse in order to capture recurrence. During the study, patients who meet the study definition of clinical recurrence will be eligible to have a blinded infliximab dose increase of 5 mg/kg. In other words, patients receiving placebo would receive infliximab 5 mg/kg, and patients receiving infliximab 5 mg/kg would have a dose increase to 10 mg/kg. Approximately 175 sites will be utilized, and approximately 290 patients will be enrolled. The interval between the first and last dose of study agent is 200 weeks. The planned duration of study participation is a maximum of 209 weeks (with a 1-week screening period, a 200-week treatment period, and a final study visit at Week 208). Group I (infliximab infusions): infliximab (5 mg/kg) will be administered by intravenous (IV) infusion at Week 0 and every 8 weeks thereafter through Week 200. Group II (placebo infusions): placebo will be administered by IV infusion at Week 0 and every 8 weeks thereafter through Week 200

What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants With Clinical Recurrence (CR) of Crohn's Disease (CD) Prior to or at Week 76
CR criteria:1) A >=70-point increase from baseline in CDAI score [in general, CDAI score ranges from 0 to approximately 600; higher score indicates higher disease activities];2)A CDAI score >=200;3)Evidence of endoscopic recurrence [ileal Rutgeerts score of >=i2 at anastomotic site or its equivalent elsewhere in GI tract] and 4)A negative stool test for C. difficile toxin (if, in the opinion of the investigator, the participant's symptoms are predominantly diarrheal); or at least 1 of followings:1) developing a new draining external fistula;2)re-opening and draining of a previously existing external fistula;3)developing a new internal fistula;4)developing a new perianal abscess or 5)developing a new intra-abdominal abscess more than 3 months after date of index surgery. In addition, participants who had a treatment failure [initiated a prohibited CD medication, had prohibited use of CD medication, or had surgery for CD] before or at Week 76 were considered to have clinical recurrence.
Measured: Baseline up to Week 76
Secondary outcomes (2)
Percentage of Participants With Endoscopic Recurrence of CD Prior to or at Week 76
Endoscopic recurrence is defined as an ileal Rutgeert's score of >= i2 either at the anastomotic site or elsewhere in the gastrointestinal tract. In addition, participants who had a treatment failure (initiated a prohibited CD medication, had a prohibited use of a CD medication, or had a surgery for CD) prior to Week 76, and who developed a new draining external fistula or re-opening and draining of a previously existing external fistula or developed a new internal fistula, new perianal abscess or new intra-abdominal abscess more than 3 months after the date of the index surgery were considered to have had endoscopic recurrence prior to or at Week 76.
Measured: Baseline up to Week 76
Percentage of Participants With Clinical Recurrence (CR) of Crohn's Disease (CD) Prior to or at Week 104
CR criteria:1) A >=70-point increase from baseline in CDAI score [in general, CDAI score ranges from 0 to approximately 600; higher score indicates higher disease activities];2)A CDAI score >=200;3)Evidence of endoscopic recurrence [ileal Rutgeerts score of >=i2 at anastomotic site or its equivalent elsewhere in GI tract] and 4)A negative stool test for C. difficile toxin (if, in the opinion of the investigator, the participant's symptoms are predominantly diarrheal); or at least 1 of followings:1) developing a new draining external fistula;2)re-opening and draining of a previously existing external fistula;3)developing a new internal fistula;4)developing a new perianal abscess or 5)developing a new intra-abdominal abscess more than 3 months after date of index surgery. In addition, participants who had a treatment failure [initiated a prohibited CD medication, had prohibited use of CD medication, or had surgery for CD]before or at Week 104 were considered to have clinical recurrence.
Measured: Baseline up to Week 104

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Infliximab in people with Crohn's Disease, run by Janssen Biotech, Inc. at 142 sites in 14 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 4 Feb 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 142 sites in United States, Canada, Germany, France, United Kingdom and 9 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 22 Oct 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of Participants With Clinical Recurrence (CR) of Crohn's Disease (CD) Prior to or at Week 76 (time frame: Baseline up to Week 76). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01190839, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Feb 2016.
