Study to Demonstrate That Antibiotics Are Not Needed in Moderate Acute Exacerbations of COPD

Phase 4
Completed
Conditions
Chronic Obstructive Pulmonary Disease (COPD)
Interventions
Drug: Placebo
Registration Number
NCT01892488
Lead Sponsor
Hannover Medical School
Brief Summary

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).

Inclusion Criteria

    • is surgically incapable of bearing children, or

    • is of childbearing potential, and the following conditions are met:

      • has a negative pregnancy test (urine- or serum-based) immediately before study entry (i.e., before the start of treatment or any other study procedure that could potentially harm the fetus), and one or more of following criteria

      • having only female sexual partners
      • sexual relationship with sterile male partners only
  • Patients diagnosed with COPD stages I-IV as defined by the Global initiative for chronic Obstructive Lung disease (GOLD).

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)
  • Fever (>38.5°C)
  • Known impaired hepatic or renal function
  • Active or suspected tuberculosis infection of the respiratory tract
  • Acute exacerbation of asthma
  • Suspected or known hypersensitivity to, or suspected serious adverse reaction to sultamicillin; suspected or known hypersensitivity to penicillins or cephalosporins
  • Immunosuppression or Immunosuppressive therapy (cytostatic chemotherapy within last 28 days or neutropenia (neutrophils < 1000/µ)l; systemic corticosteroids (≥20 mg prednisolon equivalent/day > 14 days; HIV-infection; immunosuppression after organ- or bone marrow transplant)- Patients with metastatic or hematological malignancy, splenectomized patients or patients with known hyposplenia or asplenia
  • Oral/parenteral antibiotic use within 30 days prior to randomization (a singular administration of antibiotics prior to randomization is allowed)
  • In-patient treatment within the last 30 days
  • An antibiotic is clearly indicated for treatment of a known infection
  • Known MRSA (methicillin-resistant Staphylococcus aureus) colonization or infection
  • Patients with known bronchiectasis
  • Patients with known bacterial airway colonization (>3 positive sputum cultures in the previous year)
  • 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.

Primary Outcome Measures
NameTimeMethod
Additional antibiotic therapy to study medication during treatment period or until the test of cure visit (at day 30)up to day 30

Assessment of additional antibiotic therapy:

Patients will be asked at every visit about use of additional antibiotic therapy. In the case of use of additional antibiotic therapy the exact starting date, the active compound, the dose administered, the route of administration,the length of treatment and the indication will be registered. Only additional antibiotic therapy for AE-COPD will be counted as treatment failure.

Secondary Outcome Measures
NameTimeMethod
To evaluate long-term consequences of Placebo treatmentup to 1 year

* Relapse rate

* Time to relapse

To assess patient's clinical improvement relative to treatmentup to 30 days

* Clinical cure rate at the "end of therapy visit" (at day 6)

* Clinical cure rate at the "test Of cure visit" (at day 30) (both determined by patient-centered outcomes (diary cards))

To assess additional efficacy endpoints and health outcome evaluationsup to 1 year

* Changes in COPD Assessment Test(CAT)

* Changes in Exacerbations of Chronic Pulmonary Disease Tool-Patient reported outcome (EXACT-PRO)

* Additional antibiotic therapy

* Time to next exacerbation

* Number of exacerbations during follow up

* Per-subject relapse rate at the LFU (Late Follow Up) visits in the subset of subjects in the CE population who were clinically cured at the TOC visit

* Changes in length of stay in hospital for hospitalized patients

* All cause mortality
