About this study

Official title: A Multicenter, Active-Controlled, Randomized Study to Evaluate the Safety and Efficacy of Oral Levofloxacin Versus Cefaclor in the Treatment of Acute Bacterial Exacerbation of Chronic Bronchitis in Adults

The purpose of this study is to evaluate the safety and effectiveness of levofloxacin, an antibiotic, compared with cefaclor, another antibiotic, in the treatment of adults with chronic bronchitis experiencing rapid onset of worsening of symptoms caused by bacteria.

Read the detailed description

This is a randomized, open-label, parallel group, multicenter study to determine the effectiveness and safety of 488 mg of levofloxacin (once daily by mouth for 5 - 7 days) compared with 250 mg of cefaclor (every 8 hours for 7 - 10 days) in adults with chronic bronchitis experiencing rapid onset of worsening of symptoms caused by bacterial infection. The study consists of 3 visits: one visit for screening and enrollment, and 2 visits for assessment of safety and effectiveness (one visit on Days 3 - 5 of the study and one visit [post-therapy] 5 - 7 days after the last dose of the study drug). The total duration of patient participation in the study is approximately 2 weeks. Levofloxacin and cefaclor are antibacterial agents used for the treatment of many types of infections, including infections with a rapid onset and brief duration caused by bacteria. The primary assessment of effectiveness in this study is the microbiologic response to treatment (the rate of elimination of disease-causing bacteria, by patient, and by type of bacteria), 5 - 7 days after the last dose of study drug. Safety evaluations (incidence of adverse events, physical examination, laboratory tests) are performed throughout the study. The study hypothesis is that treatment with levofloxacin is at least as effective and as well tolerated as treatment with cefaclor in adult patients with chronic bronchitis experiencing sudden worsening of symptoms caused by bacterial infection. Levofloxacin 488 mg by mouth once daily for 5 - 7 days, or cefaclor 250 mg by mouth every 8 hours for 7 - 10 days.

What is being measured

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

  1. Rate of elimination of disease-causing bacteria, by patient, and by type of bacteria, 5 - 7 days after the last dose of study drug.

Secondary outcomes (1)
  1. Clinical response rate (reduction in signs and symptoms) at post-therapy (5 - 7 days after the last dose of study drug). Incidence of adverse events; changes in physical examination and laboratory tests after treatment with the study drug.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing levofloxacin in people with Bronchitis and Bronchitis, Chronic, 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 5 inclusion and 5 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 10 Jun 2011. 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 combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Rate of elimination of disease-causing bacteria, by patient, and by type of bacteria, 5 - 7 days after the last dose of study drug.. 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 NCT00257140, 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 10 Jun 2011.
