About this study
The purpose of this study is to evaluate the safety and effectiveness of four oral antibiotic treatment regimens for bacterial infections in patients with chronic bronchitis. The study goals are to demonstrate that 1) levofloxacin 750 mg once daily for three days is no worse than azithromycin 250 mg twice a day for one day and then 250 mg once a day for four more days, and 2) levofloxacin 750 mg once daily for five days is no worse than amoxicillin/ clavulanate (875/125 mg) twice daily for 10 days.
Read the detailed description
This is a randomized, double-blind, multicenter treatment study to evaluate the efficacy and safety of high-dose, short-course oral levofloxacin treatment versus treatment with other oral antibiotics in acute bacterial exacerbation of chronic bronchitis (ABECB). This study evaluates the use of high-dose (750 milligrams) and short-course (3 or 5 days) levofloxacin compared with conventional doses and schedules of other effective antibiotics for controlling acute bacterial infections in patients with chronic bronchitis, The study will divide the 700 patients into two groups--one group with less severe (uncomplicated) chronic bronchitis, and one with more severe (complicated) chronic bronchitis. Patients with uncomplicated disease will receive levofloxacin 750 mg once daily for 3 days or azithromycin 250 mg twice a day for 1 day and then 250 mg once a day for 4 more days. Patients with complicated disease will receive levofloxacin 750 mg once daily for 5 days or amoxicillin/ clavulanate (875/125 mg) twice daily for 10 days. All patients will take study medication orally. Effectiveness will be measured by comparing the patient's signs and symptoms present at the Test-of-Cure Visits (study days 13 - 22) with those observed at the Study Entry Visit. Safety will be evaluated throughout the study on the basis of the occurrence and severity of unexpected and undesirable events as well as by laboratory tests and physical examinations. The hypothesis of the study is that a shorter course (3 days) of 750 mg levofloxacin will be at least as effective and well tolerated as azithromycin for 5 days for uncomplicated ABECB, and that 750 mg of levofloxacin for 5 days will be at least as effective and well tolerated as amoxicillin/ clavulanate for 10 days for curing complicated ABECB cases.
Uncomplicated ABECB: Oral doses of levofloxacin 750 mg once daily for 3 days, or azithromycin 250 mg twice daily on day 1, then 250 mg once daily on days 2 - 5. Complicated ABECB: Oral doses of levofloxacin 750 mg once daily for 5 days, or amoxicillin/clavulante 875/125 mg once daily for 10 days.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing levofloxacin, azithromycin, amoxicillin/clavulanate in people with Bronchitis and Chronic Bronchitis, run by Johnson & Johnson Pharmaceutical Research & Development, L.L.C..
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 3 inclusion and 4 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 28 Apr 2010. 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?
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?
Clinical response rates based on signs and symptoms at posttherapy visit.. 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 NCT00042718, 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 28 Apr 2010.
