What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Left Colon Mucosal Blood Flow (MBF)

    On Day 6 of each treatment period; 1 hour after dosing, subjects underwent a flexible sigmoidoscopy with Laser Doppler Flowmetry (LDF) to measure Mucosal Blood Flow (MBF). There were no pre-treatment LDF procedure, MBF was compared between the Healthy volunteers and D-irritable bowel syndrome (IBS) cohorts using the flow rates from the placebo treatment period.

    Measured: Day 6 after each treatment period

Secondary outcomes (2)
  1. Rectal Mucosal Blood Flow (MBF)

    On Day 6 of each treatment period approximately 1 hour after dosing, subjects underwent a flexible sigmoidoscopy with Laser Doppler Flowmetry (LDF) to measure Mucosal Blood Flow (MBF). There was no pre-treatment LDF procedure, MBF was compared between the Healthy and d-IBS cohorts using the flow rates from the placebo treatment period.

    Measured: Day 6 after each treatment period

  2. Left Colon and Rectal Mucosal Blood Flow Cohort Comparisons

    On Day 6 of each treatment period approximately 1 hour after dosing, subjects underwent a flexible sigmoidoscopy with Laser Doppler Flowmetry (LDF) to measure Mucosal Blood Flow (MBF). There was no pre-treatment LDF procedure, MBF was compared between the Healthy and d-IBS cohorts using the flow rates from the placebo treatment period.

    Measured: Day 6 after each treatment period

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing alosetron in people with Irritable Colon, run by GlaxoSmithKline at 1 site in United Kingdom.

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 15 inclusion and 45 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 18 May 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. 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. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 2 Apr 2009). 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?

Left Colon Mucosal Blood Flow (MBF) (time frame: Day 6 after each treatment period). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 18 May 2015.
