Details and patient eligibility

About

The ultimate goal is to reduce unnecessary antibiotic prescriptions which drive the development of antibiotic resistance in the community. The primary objective of ABACOPD is to demonstrate in a sufficiently sized clinical study that there is no relevant increase in the "failure-rate" for patients with acute moderate exacerbations of COPD (AE-COPD) treated with placebo instead of antibiotic treatment both on top of standard of care. A patient is classified as treatment failure if additional antibiotic therapy is required during treatment period or until the test of cure visit (TOC at day 30, primary endpoint).

and

  • Doctor's diagnosis of acute (onset < 7 days) moderate exacerbation of COPD defined by a sustained worsening of the patient's condition (including at least 2 of the following symptoms: increased dyspnea, increased sputum production, sputum purulence and increased cough), from the stable state and beyond normal day-to-day variations, necessitating a change in regular medication in patient with underlying COPD, needing additional medical assistance.
  • Absence of community acquired pneumonia or lower respiratory tract infection with a clear indication for antibiotic treatment as determined by Procalcitonin level < 0.25 ng/mL and/or absence of pulmonary infiltrates on routine chest x-ray.
  • Smoking history of at least 10 Pack Years or more.
  • Patients must be able to complete diaries and quality of life questionnaires.
  • Patients must sign and date an informed consent prior to any study procedures.

Exclusion criteria

  • Severe exacerbation: defined by need for ventilatory support (indicated by severe dyspnea with failure to respond to emergency treatment and/or persistent hypoxemia (PaO2 <50 mm Hg despite O2 administration and / or respiratory acidosis (pH <7.35 and PaCO2> 45mmHg)) or mental confusion or circulatory insufficiency (need of vasopressors)

  • An antibiotic is clearly indicated for treatment of a known infection
  • Known MRSA (methicillin-resistant Staphylococcus aureus) colonization or infection
  • Patients with known bronchiectasis

  • Progressively fatal disease, or life expectancy ≤6 months
  • Mononucleosis
  • Lymphatic leukemia
  • Severe gastro-intestinal disorders with vomiting and diarrhea
  • Women who are breast feeding
  • Patients who have received treatment with any other investigational drug within 1 month prior to study entry, or have such treatment planned for the study period during treatment and follow up phase.
  • Patients with mental conditions rendering them unable to understand the nature, scope, and possible consequences of the study.
  • Patients unlikely to comply with the protocol, e.g., uncooperative attitude, inability to return for follow up visits, and unlikelihood of completing the study.
