About this study

Official title: A Study to Investigate the Gastrointestinal Safety of OTC Analgesics in Healthy Volunteers by Endoscopic Examination

What is being measured

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

  1. Gastromucosal Damage (GMD) Score of Paracetamol Tablet vs Ibuprofen Capsule

    Endoscopic examination of the upper gastrointestinal mucosa evaluated the extent of mucosal injury to the stomach and the duodenum separately using a 5-point Lanza scale, ranging from 0: normal stomach; 1: mucosal hemorrhages; 2: one or two erosions; 3: numerous areas of erosions; and 4: more than 10 erosions or ulcer.

    Measured: Day 7

Secondary outcomes (4)
  1. GMD Scores of Paracetamol Tablet; Ibuprofen Capsule; Ibuprofen Tablet; and Placebo Tablet

    Endoscopic examination of the upper gastrointestinal mucosa evaluated the extent of mucosal injury to the stomach and the duodenum separately using a 5-point Lanza scale, ranging from 0: normal stomach; 1: mucosal hemorrhages; 2: one or two erosions; 3: numerous areas of erosions; and 4: more than 10 erosions or ulcer.

    Measured: Day 7

  2. Duodenal Mucosal Damage (DMD) Scores

    DMD was measured using a 5- point Lanza scale: 0 - normal duodenum; 1 - mucosal hemorrhages; 2 - one or two erosions; 3 - numerous areas of erosions and 4 - more than 10 erosions/ ulcers.

    Measured: Day 7

  3. Incidence of Gastric and/or Duodenal Mucosal Injury

    Number of participants with endoscopy score equal to or more than 2 were determined based on Lanza score for both gastric and duodenal mucosal damage.

    Measured: Day 7

  4. Incidence of Fecal Occult Blood

    The incidence of fecal occult blood was recorded as a binary response (0 = no presence of blood; 1 = presence of blood).

    Measured: Day 7

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ibuprofen and Paracetamol in people with Gastrointestinal Mucosal Damage, run by GlaxoSmithKline at 1 site 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 4 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 31 Mar 2014. 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 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 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 31 Mar 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?

Gastromucosal Damage (GMD) Score of Paracetamol Tablet vs Ibuprofen Capsule (time frame: Day 7). 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 31 Mar 2014.
