What is being measured
The primary outcome is the main question the study is designed to answer.
Percent of Subjects Without Recurrence of Diverticulitis
Recurrence of diverticulitis is defined as the presence of each and all of the following 3 items: 1) abdominal pain, 2) a 15% increase in white blood cell count from baseline, 3) bowel wall thickening (>5 mm) and/or fat stranding as evidenced by spiral computerized axial tomography (CT) scan; OR surgical intervention for diverticular disease. Withdrawals are considered as recurrences.
Measured: Up to 104 weeks
Secondary outcomes (6)
Percent of Subjects Who Were CT-Recurrence Free of Diverticulitis
CT-recurrence of diverticulitis is defined as: a positive spiral CT scan for diverticulitis showing, at a minimum, fat stranding with or without bowel wall thickening >5 mm or surgical intervention for diverticular disease. Withdrawals considered as CT-recurrences.
Measured: Up to 104 weeks
Number of CT Scans Performed Within 7 Days of Suspected Recurrence of Diverticulitis That Were Positive
A positive CT scan was defined as a CT scan that showed bowel wall thickening (>5 mm) and/or fat stranding as read by the central reader.
Measured: Up to 104 weeks
Number of CT Scans Performed Within 7 Days of Suspected Recurrence of Diverticulitis That Were Negative
A negative CT scan was defined as a CT scan that did not show bowel wall thickening (>5 mm) and/or fat stranding as read by the central reader.
Measured: Up to 104 weeks
Number of CT Scans Performed More Than 7 Days From Suspected Recurrence of Diverticulitis That Were Positive
A positive CT scan was defined as a CT scan that showed bowel wall thickening (>5 mm) and/or fat stranding as read by the central reader.
Measured: Up to 104 weeks
Number of CT Scans Performed More Than 7 Days From Suspected Recurrence of Diverticulitis That Were Negative
A negative CT scan was defined as a CT scan that did not show bowel wall thickening (>5 mm) and/or fat stranding as read by the central reader.
Measured: Up to 104 weeks
Percent of Subjects Requiring Surgery for Diverticulitis
Measured: Up to 104 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing SPD476 (1.2g), SPD476 (2.4 g) and SPD476 (4.8 g) in people with Diverticulitis, run by Shire at 121 sites in 11 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 4 inclusion and 14 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: finished, as of the sponsor's last update on 14 Jun 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 121 sites in United States, Israel, France, India, Australia and 6 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 25 Jan 2013). 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?
Percent of Subjects Without Recurrence of Diverticulitis (time frame: Up to 104 weeks). 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 NCT00545740, 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 14 Jun 2021.
