About this study
Official title: Phase 4 Study Into the Effect of Minocycline and Amoxicillin Administration of the Prevalence of Antibiotic Resistant Bacteria and on the Indigenous Oral, Faecal, Cutaneous and Nasal Microbiotas
A randomised, open labelled study design is selected in order to determine the emergence and persistence of antibiotic resistant bacteria in humans and on the composition of the indigenous microbiotas at various body sites. These will involve the administration to volunteers of minocycline and amoxicillin- a control group will receive a placebo. Microbiology of the skin, saliva, faecal, skin and nasal micro flora, safety and adverse events, vital signs, will be evaluated. The objectives of metagenomic analysis are:
- To identify the in vivo molecular mechanisms responsible for antibiotic resistance and its transfer in the indigenous oral and faecal microbiotas using metagenomics resistome analysis.
- To determine the impact of the use of antimicrobial agents on the oral resistome
- To determine the impact of the use of antimicrobial agents on the faecal resistome
- To determine the ecological impact of the use of antimicrobial agents on the relative abundance of phylotypes of the indigenous oral microbiota
- To determine the ecological impact of the use of antimicrobial agents on the relative abundance of phylotypes of the indigenous faecal microbiotas
- Conditions
- Antibiotic Resistant Bacteria
- Being tested
- 3 doses of amoxicillin daily for 7 days, 2 doses of minocycline daily for five days, 2 doses of placebo daily for five days
- Keywords
- The impact of a number of different types of antibiotics, The emergence and persistence of antibiotic resistance

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing 3 doses of amoxicillin daily for 7 days and 2 doses of minocycline daily for five days in people with Antibiotic Resistant Bacteria, run by Helperby Therapeutics Ltd at 1 site in United Kingdom.
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 12 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 9 Jan 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 Kingdom. 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?
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?
Percentage of resistant bacteria collected from body sites in subjects receiving minocycline/ amoxicillin compared to the baseline. (time frame: 12 Months). 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 9 Jan 2014.
