What is being measured

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

  1. Harris Hip Score

    The Harris Hip Score was developed to assess hip disabilities and methods of treatment and has been in use for decades. It evaluates patients on the basis of pain, function, absence of deformity and range of motion. The Harris Hip Score could range from 0 to 100. Scores less then 70 are poor, scores 70 to 79 are fair, scores 80 to 89 are good, and scores 90 to 100 are excellent.

    Measured: Pre-op, 3 Month Post-Op and Annual Post-Op visits through 5 Years

Secondary outcomes (1)
  1. Continued Assessment of Implant Survivorship and Incidences of Adverse Events.

    A total of 37 Adverse Events were reported. There have been no UADEs reported in this study population. At the time of site closure all AEs were resolved or tolerated. Implant survivorship not reportable due to early study termination.

    Measured: At all follow-up visits through 5 Years and postcard follow-up 6 - 10 Years

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Trilogy AB Acetabular Hip Implant System in people with Osteoarthritis and Avascular Necrosis, run by Zimmer Biomet at 2 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 4 inclusion and 16 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 26 Nov 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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. 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 26 Nov 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?

Harris Hip Score (time frame: Pre-op, 3 Month Post-Op and Annual Post-Op visits through 5 Years). 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 26 Nov 2014.
