About this study
Official title: Multi-Center Phase 3 Trial of Minocycline HCl 1 mg Microspheres for the Use in Subjects With Peri-Implantitis: Clinical and Microbiological Evaluations
The objective of the study is to evaluate the safety, effectiveness and anti-microbial effects of Arestin (minocycline HCl) 1 mg Microspheres in the treatment of subjects with peri-implantitis, when used in combination with mechanical debridement.
The hypothesis of the study is that Arestin in combination with mechanical debridement is more effective in the treatment of peri-implantitis when compared to mechanical debridement alone. The primary efficacy measure will be the reduction of probing depth at Day 180 as measured at qualifying implant sites.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Minocycline HCl Microspheres in people with Peri-Implantitis, run by OraPharma at 10 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 5 inclusion and 9 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 26 Aug 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 10 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 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Change in mean Probing Depth of qualifying implant sites (time frame: Baseline to Day 180). 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 Aug 2015; AzTrials last refreshed its copy on 6 Nov 2026.
