Detailed Summary:
Sponsor: Bayer
Current Primary Outcome: Clinical failure at 8 weeks post therapy [ Time Frame: At day 63 ]
Original Primary Outcome: The primary efficacy variable is clinical failure at 8 weeks post therapy. [ Time Frame: 18 months ]
Current Secondary Outcome:
- Clinical failure rates [ Time Frame: Through to day 35 ]
- Bacteriological eradication rates [ Time Frame: Through to day 63 ]
- Clinical failure rates for subjects with positive sputum culture at enrollment [ Time Frame: Through to day 63 ]
- Weekly mean symptom scores measured by the AECB SS [ Time Frame: Through to day 63 ]
- Rates and speed of symptom relief measured by the AECB SS [ Time Frame: Through to day 63 ]
- Clinical failure rates for subjects with co-administration of systemic corticosteroids (stratum 1) [ Time Frame: Through to day 63 ]
- Clinical failure rates for subjects without co-administration of systemic corticosteroids (stratum 2) [ Time Frame: Through to day 63 ]
- Need for any change in dosage or additional respiratory medication such as bronchodilators and inhaled steroids, excluding short acting bronchodilators [ Time Frame: Through to day 63 ]
- Improvement in symptoms burden measured by the AECB SS [ Time Frame: Through to day 63 ]
- Improvement in health related QoL measured by the SGRQ [ Time Frame: Through to day 63 ]
- spirometry tests will be compared between treatment groups [ Time Frame: Through to day 63 ]
- HCRU relat. to chronic bronchitis management incl. rescue med., concomitant med., therap. adjuncts, diagn. procedures, other medical care/medical staff requirement, hospitalizations (incl. ward and duration), and work productivity and activity impairment [ Time Frame: Through to day 63 ]
- Safety and tolerability of moxifloxacin versus amoxicillin clavulanic acid, with particular attention to rates of diarrhea [ Time Frame: Through to day 63 ]
Original Secondary Outcome:
- The secondary efficacy variables are:- clinical efficacy rates at the During Therapy, EOT, and 4 weeks Post therapy [ Time Frame: 18 months ]
- Bacteriological eradication rates at During Therapy, EOT, 4 weeks Post therapy, and 8 weeks Post therapy visits [ Time Frame: 18 months ]
- Clinical efficacy rates for subjects with positive sputum culture at enrollment at the During Therapy, EOT, 4 weeks Post therapy, and 8 weeks Post therapy visits [ Time Frame: 18 months ]
- Weekly mean symptom scores measured by the AECB SS [ Time Frame: 18 months ]
- Rates and speed of symptom relief measured by the AECB SS [ Time Frame: 18 months ]
- Need for any change in dosage or additional respiratory medication such as bronchodilators and inhaled steroids, excluding short acting bronchodilators [ Time Frame: 18 months ]
- Improvement in symptoms burden measured by the AECB SS [ Time Frame: 18 months ]
- Improvement in health related QoL measured by the SGRQ [ Time Frame: 18 months ]
- Lung function test will be compared between treatment groups at each assessment visit [ Time Frame: 18 months ]
- HCRU related to chronic bronchitis management including rescue medications, concomitant medications, therapeutic adjuncts, diagnostic procedures, [ Time Frame: 18 months ]
- Other medical care/medical staff requirement, hospitalizations (including ward and duration), and work productivity and activity impairment [ Time Frame: 18 months ]
- Safety and tolerability of moxifloxacin versus amoxicillin clavulanic acid, with particular attention to rates of diarrhea [ Time Frame: 18 months ]
