What is being measured

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

  1. Number of Participants Classified as an Overall Responder for Abdominal Pain

    An overall responder for abdominal pain is defined as a participant who is a weekly responder for at least 75% of observed treatment weeks.

    Measured: within 12 weeks

Secondary outcomes (8)
  1. Number of Participants Classified as a Weekly Responder for Abdominal Pain

    Participants rate their pain on a pain intensity scale where 0=no pain and 10=worst pain. A higher score means the pain is worse.

    A weekly responder for abdominal pain is defined as a participant reporting ≥ 30% reduction from baseline in average of 24-hour worst abdominal pain scores for the preceding week.

    Measured: within 12 weeks

  2. Number of Participants Classified as a Monthly Responder for Abdominal Pain

    A monthly responder for abdominal pain is defined as a participant who is a weekly responder for abdominal pain at least 2 of 4 weeks in the preceding month.

    Measured: within 3 months

  3. Number of Participants Classified as a Weekly Responder for Stool Consistency

    A weekly responder for stool consistency is defined as a participant having at least 50% reduction from baseline in percentage of days with extreme stool consistency for a given week.

    Measured: within 12 weeks

  4. Number of Participants Classified as a Monthly Responder for Stool Consistency

    A monthly responder for stool consistency is defined as a participant who is a weekly responder for stool consistency at least 2 of 4 weeks in the preceding month.

    Measured: within 3 months

  5. Number of Participants Classified as an Overall Responder for Stool Consistency

    An overall responder for stool consistency is defined as a participant who qualifies as a weekly responder for stool consistency for at least 75% of observed treatment weeks.

    Measured: within 3 months

  6. Number of Participants Classified as a Weekly Responder for Irritable Bowel Syndrome (IBS) Symptoms

    A participant who achieves adequate relief of IBS symptoms during the preceding week is classified as a weekly responder for IBS symptoms.

    Measured: within 12 weeks

  7. Number of Participants Classified as a Monthly Responder for IBS Symptoms

    A participant who is a weekly responder for IBS symptoms for at least 2 of the 4 weeks in the preceding month is classified as a monthly responder for IBS symptoms.

    Measured: within 3 months

  8. Number of Participants Classified as an Overall Responder for IBS Symptoms

    A participant who is a weekly responder for IBS symptoms for at least 75% of observed treatment weeks is classified as an overall responder for IBS symptoms.

    Measured: within 3 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Lubiprostone in people with Irritable Bowel Syndrome, run by Sucampo Pharma Americas, LLC at 16 sites in United States.

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 3 inclusion and 3 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 27 Dec 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 16 sites in United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 27 Dec 2019). 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?

Number of Participants Classified as an Overall Responder for Abdominal Pain (time frame: within 12 weeks). 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 27 Dec 2019.
