BAY12-8039: 5 Days for Sinusitis vs Placebo

• Treatment Day When Patients Reached Symptom Improvement as Measured by Patient Reported Data, Using Last Observation Carried Forward (LOCF) Approach [ Time Frame: Daily until 'Test-Of-Cure' (Day 1-5 after end of treatment) ] [ Designated as safety issue: No ]
  The Sino-Nasal Outcome Test (SNOT-16) was used to assess subject-reported time to symptom improvement. Improvement was defined as a decrease of at least 14 units on the test. This difference is the smallest difference that has been identified as beneficial to subjects.
• Treatment Day When Patients Returned to Normal Activities as Measured by Patient Reported Data, Using LOCF Approach [ Time Frame: Daily until 'Test-Of-Cure' (Day 1-5 after end of treatment) ] [ Designated as safety issue: No ]
  The Activity Impairment Assessment (AIA) questionnaire was used to assess activity impairment at baseline and time to return to normal activities. The AIA was administered prior to first dose, every 24 hours during treatment, and at the TOC visit. Improvement in the AIA total score was defined as a decrease of at least 3 units.
• Percentage of Subjects With Clinical Improvement During Therapy [ Time Frame: Day 3 of treatment ] [ Designated as safety issue: No ]
  A secondary efficacy variable was clinical response (CR) at the During Therapy visit at day 3 or 4 of treatment. CR was rated as improvement, cure, failure, or indeterminate. Clinical evaluation was based on the presence and severity (mild, moderate, or severe) of several signs and symptoms of acute sinusitis.
• Percentage of Subjects With Continued Clinical Cure During Long-Term Follow-Up [ Time Frame: Day 12 to 26 after end of treatment ] [ Designated as safety issue: No ]
  A secondary efficacy variable was clinical response (CR) at the Follow-up visit 17-21 days following the start of treatment. CR was rated as continued cure, failure/relapse, or indeterminate. Clinical evaluation was based on the presence and severity (mild, moderate, or severe) of several signs and symptoms of acute sinusitis.

The purpose of the study is to evaluate the effectiveness and safety of Avelox in a 5 day treatment of adult patients with acute bacterial sinusitis and to measure the amount of time it takes for symptom relief. Avelox is currently not approved for the 5 day treatment of acute bacterial sinusitis, therefore in this study Avelox is considered an investigational drug. In this study Avelox will be compared to placebo.

Inclusion Criteria:

Subjects must meet all the following criteria at the time of enrollment:

• Age >/= 18 years

• Clinical diagnosis of acute bacterial sinusitis with signs and symptoms present for = 7 days but < 28 days as defined by A), radiographic, and B) clinical criteria, as follows:

  • Radiographic Criteria: The presence of one or more of the following on a radiographic paranasal sinus film (Waters' view): - Evidence of air-fluid levels - Opacification

  • Clinical Criteria: The presence of two major symptoms, or the presence of at least one major and one minor symptom as defined in the list below:

    • Major symptoms: - Purulent anterior or posterior nasal discharge - Unilateral facial pain or malar tenderness
    • Minor symptoms: - Frontal headache - Fever (oral = 38.0°C/100.4°F, tympanic = 38.5°C/101.2°F, axillary = 37.5°C/99.5°F) - Culture material obtained by sinus puncture; the aspirated specimen sent for Gram stain, quantitative culture and susceptibility testing prior to initiation of antimicrobial therapy

Exclusion Criteria:

Subjects with one or more of the following criteria will not be eligible for this study:

• History of chronic sinusitis defined as greater than four weeks of continuous symptoms (subjects with recurrent acute sinusitis will be included)
• History of sinus surgery (antral sinus puncture is not considered as a surgery)
• Any symptoms that suggest the subject's current illness is allergic rhinitis (e.g. repetitive sneezing, itchy nose or eyes, provocation by an allergen) and not acute bacterial sinusitis
• Known bacteremia, meningitis or infection infiltrating the tissues neighboring the sinuses
