About this study

Official title: A Randomized, Double-Blind, Phase 3 Study of the Efficacy and Safety of HZT-501 in Subjects Requiring NSAID Treatment

The purpose of this study is to evaluate whether HZT-501 is effective in reducing the rate of development of ibuprofen-associated ulcers in patients who require long-term daily use of ibuprofen.

Read the detailed description

HZT-501 is a combination product including ibuprofen and the acid reducing agent famotidine. The study is designed to determine whether the combination product reduces the rate of ulcer development in subjects who require long-term daily use of ibuprofen.

Subjects will be assigned randomly, in approximately a 2:1 ratio, to treatment with either HZT-501 (ibuprofen 800 mg/famotidine 26.6 mg) or ibuprofen (800 mg) three times daily for a 24 week treatment period or until they develop either an endoscopically-diagnosed upper gastrointestinal ulcer and/or prohibitive toxicity. Subjects will visit the study center for Screening and at Weeks 4, 8, 16, and 24. Physical exams will be performed, and clinical laboratory measurements made, at selected times during the study. Endoscopic exams will be performed during Screening and at Weeks 8, 16, and 24. Subjects will be contacted four weeks following study completion.

What is being measured

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

  1. Number of Subjects Who Develop Endoscopically-diagnosed Upper Gastrointestinal Ulcers Confirmed by Endoscopy.

    The primary efficacy endpoint was the number of subjects with upper gastrointestinal (i.e., gastric and/or duodenal) ulcer at any time throughout 24 weeks of treatment. An ulcer was defined as a mucosal break of at least 3 mm in diameter with unequivocal depth. A subject is considered to have completed the study if all scheduled assessments up through the Week 24 visit have been performed.

    Measured: 24 weeks

Secondary outcomes (3)
  1. Number of Subjects Who Develop Endoscopically-diagnosed Gastric Ulcers During the 24-week Treatment Period.

    The secondary efficacy endpoint was the number of subjects with gastric ulcer at any time throughout 24 weeks of treatment. An ulcer was defined as a mucosal break of at least 3 mm in diameter with unequivocal depth. A subject is considered to have completed the study if all scheduled assessments up through the Week 24 visit have been performed.

    Measured: 24 weeks

  2. Number of Subjects Who Develop Endoscopically-diagnosed Duodenal Ulcers During the 24-week Treatment Period.

    The secondary efficacy endpoint was the number of subjects with duodenal ulcer at any time throughout the 24 weeks of treatment. An ulcer was defined as a mucosal break of at least 3 mm in diameter with unequivocal depth. A subject is considered to have completed the study if all scheduled assessments up through the Week 24 visit have been performed.

    Measured: 24 weeks

  3. The Incidence Rate of NSAID-associated Serious Gastrointestinal Complications.

    The secondary efficacy endpoint was the number of subjects developing a NSAID-associated serious GI complication at any time throughout 6 months of treatment. A NSAID-associated serious GI complication was defined as a perforation of ulcers, gastric outlet obstruction due to ulcers, and/or GI bleeding.

    Measured: 24 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing HZT-501 and Ibuprofen in people with Peptic Ulcer, run by Amgen.

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 2 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 16 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

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 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 21 Jun 2011). 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 Subjects Who Develop Endoscopically-diagnosed Upper Gastrointestinal Ulcers Confirmed by Endoscopy. (time frame: 24 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 NCT00450658, 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 16 Dec 2024.
