Brief Summary:

The purpose of the study is to investigate, in patients with moderate to severe chronic obstructive lung disease, whether intermittent antibiotic treatment leads to:

  • A slower rate of decline in forced expiratory volume in one second (FEV1);
  • A reduction in the frequency and severity of exacerbations;
  • Fewer hospital admissions for chronic obstructive pulmonary disease (COPD);
  • Lower mortality;
  • An improved quality of life as compared to a group of placebo treated patients.

Condition or disease Intervention/treatment Phase
Pulmonary Disease, Chronic Obstructive Drug: azithromycin Phase 4

Drug Dose: 500 mg once daily for 3 days every month.

Duration of Treatment: 3 years

Number of Evaluable Patients: 200 per treatment arm

Number of Included Patients: 400 per treatment arm, 800 patients in total.

Ages Eligible for Study:   50 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patients above 50 years of age, with a current admission for exacerbation of COLD or at least one admission within the previous two years.
  • Current or ex-smoker
  • Postbronchodilator FEV1 < 60% in stable condition (> 4 weeks after hospitalisation)
  • < 300 ml bronchodilator reversibility in FEV1

Exclusion Criteria:

  • Patients with end-stage COLD, who are not expected to survive for 3 years (typically bedridden patients being dyspnoeic in rest).
  • Patients with known other respiratory tract infection, e.g. tuberculosis or aspergillosis, in whom the intervention is known to be inefficient.
  • Patients with pulmonary malignancy
  • Patients with other pulmonary diseases than COLD.
  • Patients with immunodeficiency. However, COLD patients treated with steroids can be included.
  • Patients with known hereditary disposition to lung infections such as alfa-1-antitrypsin deficiency, cystic fibrosis or primary ciliary dyskinesia.
  • Patients receiving longterm antibiotic treatment ( e.g. recurrent cystitis).
  • Patients with known allergy or intolerance to azithromycin
  • Pregnant or breastfeeding women
  • Manifest heart, liver or renal insufficiency
  • Patients that, for reasons not stated above, are unlikely to be able to participate in a study period of 3 years.
