A Study of the Safety and Effectiveness of Oral Levofloxacin Compared With Cefuroxime Axetil in the Treatment of Adults With Persistent Bronchitis Experiencing Rapid Onset of Severe Worsening of Symptoms Caused by Bacteria

Condition(s) targeted: Bronchitis, Chronic

Intervention: levofloxacin (Drug)

Phase: Phase 3

Status: Completed

Sponsored by: Johnson & Johnson Pharmaceutical Research & Development, L.L.C.

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

Official title: A Multicenter, Randomized Study to Compare the Safety and Efficacy of Oral Levofloxacin With That of Cefuroxime Axetil in the Treatment of Acute Bacterial Exacerbation of Chronic Bronchitis in Adults

Study design: Treatment, Randomized, Open Label, Active Control, Parallel Assignment, Safety/Efficacy Study

Primary outcome: Clinical response rate (reduction in signs and symptoms) at post-therapy (5 - 7 days after the last dose of study drug)

Secondary outcome: Rate of elimination of disease-causing bacteria, by patient, and by type of bacteria; incidence of adverse events; changes in physical examination and laboratory tests after the last dose of study drug

Detailed description: This is a randomized, open-label, parallel group, multicenter study to determine the safety

and effectiveness of 500 mg of levofloxacin (once daily for 5 - 7 days) compared with 250 mg

of cefuroxime axetil (every 12 hours for 10 days) in adults with chronic bronchitis experiencing rapid onset of severe worsening of symptoms caused by bacteria. 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. The primary efficacy assessment is the clinical

response 5 - 7 days after the last dose of study drug, (categorized as cured, improved, or

failed) based upon changes in signs and symptoms. 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 cefuroxime axetil in adult patients with chronic bronchitis experiencing sudden worsening of symptoms caused by bacterial infection.

Levofloxacin 500 mg by mouth once daily for 5 - 7 days, or cefuroxime axetil 250 mg by mouth

every 12 hours for 10 days

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion Criteria:

- Diagnosis of chronic obstructive lung disease (chronic bronchitis and/or emphysema)

with rapid onset of worsening of symptoms caused by bacterial infection

- Recent increase in cough

- Change in type or amount of sputum (the mucus produced on coughing)

- Findings during the physical examination of clinical signs and symptoms of chronic

obstructive lung disease

- Received previous antibiotic treatment if the previous treatment lasted for 24 hours

or less, or if the previous treatment lasted longer than 24 hours but there was no improvement or stabilization of the disease

Exclusion Criteria:

- Illness requiring antibiotic treatment by injection into a vein, beneath the skin, or

into a muscle, or patient has a requirement for a second antibiotic medication taken orally in addition to the study drug

- Infection due to bacteria known (prior to the start of the study) to be resistant to

the study drugs

- Previous allergic or serious adverse reaction to antibiotics similar to the study

drugs

- Diagnosis of pneumonia determined by x-ray at the start of the trial

- Has cystic fibrosis, seizure disorders, kidney disease, or an unstable psychiatric

condition
