About this study
Official title: Phase 4 Efficacy Study of Antimicrobials in the Treatment of Acute Otitis Media in Young Children
This is a prospective, randomized, double-blind, placebo controlled one-center study carried out in primary care setting of the health center of City of Turku, Finland. The study patients will be allocated to one of the two parallel treatment groups (amoxicillin-clavulanate or placebo). The hypothesis is that the symptoms and signs of acute otitis media are resolved more effectively with antimicrobial treatment than with placebo. Furthermore, this study aims at finding out prognostic factors that could help to direct antimicrobial treatment for correct subgroups of young patients.
- Conditions
- Acute Otitis Media
- Being tested
- amoxicillin-clavulanate, Placebo
- Medical subject headings
- Otitis Media
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
amoxicillin-clavulanateDrug
Amoxicillin clavulanate 40 mg/kg/day divided into two daily doses for 7 days. Capsules will be produced by pulverizing amoxicillin clavulanate tablets (Augmentin 875 mg; manufacturer Glaxo SmithKline Beecham; ATC Code: J01CR02) and mixing that with lactose monohydrate. Each capsule will contain Augmentin tablet powder 68 mg and lactose monohydrate 572 mg. This means amoxicillin 40 mg and clavulanate 5,7 mg respecting the dose per 2 kg.
PlaceboDrug
Placebo twice a day for 7 days. Placebo capsules contain lactose monohydrate 640 mg.
| Study group | Role | What they receive |
|---|---|---|
| 1 | Experimental | Reconstituted amoxicillin-clavulanate at 40/5.7 mg/kg/day in 2 divided doses for 7 days. Receives: Drug: amoxicillin-clavulanate |
| 2 | Placebo comparator | Reconstituted placebo in 2 divided doses for 7 days. Receives: Drug: Placebo |

Measured: First 7 days of follow-up
Compare the incidence of adverse events accompanying the 2 treatment regimens
Measured: Duration of study
Time to resolution of middle ear fluid in the ear(s) that is affected on study day 1
Measured: Duration of study

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing amoxicillin-clavulanate in people with Acute Otitis Media, run by University of Turku at 2 sites in Finland.
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 13 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: status not confirmed, as of the sponsor's last update on 11 Feb 2009. 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 Finland. 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?
Results are not available in the source record.
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?
Compare time to treatment failure in children receiving amoxicillin-clavulanate to children receiving placebo (time frame: During the first 8 days of follow-up). 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 NCT00299455, which also lists 7 linked publications.
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 11 Feb 2009; AzTrials last refreshed its copy on 8 Nov 2026.
