NCT02088216

Brief Summary

Objective: To evaluate whether long-term oral N-acetylcysteine as an expectorant drug can reduce the frequency of acute exacerbations of patients with non-cystic fibrosis bronchiectasis and improve their quality of life. Methods: Patients with non-cystic fibrosis bronchiectasis will be randomly assigned to the observer group (participants receive 600 mg of oral N-acetylcysteine BID for 12 months) or the control group (participants receive oral tablet BID for 12 months). The primary endpoint was the frequency of acute exacerbations. Expected results: Compared with the control group, the frequency of acute exacerbations of the observer Group will decrease significantly. Hypothesis: Long-term oral N-acetylcysteine can reduce the frequency of acute exacerbations of patients with non-cystic fibrosis bronchiectasis and improve their quality of life.

Outcome Measures

Primary Outcomes (1)

  • Median Number of Exacerbations

    An exacerbation of bronchiectasis is defined as either a change in one or more of the common symptoms of bronchiectasis (sputum volume or purulence, dyspnea, cough, and fatigue/malaise) or the onset of new symptoms (fever, pleurisy, haemoptysis or need for antibiotic treatment).

    12 months

Secondary Outcomes (10)

  • Change of Volume of Sputum From Baseline Parameters After the 12-month Follow-up.

    12 months

  • Change of Number of Patients With a Positive Sputum Culture for Pseudomonas Aeruginosa

    12 months

  • Change of Chronic Obstructive Pulmonary Disease Assessment Test (CAT) Scores From Baselines

    12 months

  • Change in Percentage of Predicted Forced Expiratory Volume in One Second (FEV1%) From Baselines

    12 months

  • Change of Forced Expiratory Volume in One Second (FEV1) (L) From Baselines

    12 months

  • +5 more secondary outcomes

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • subjects were aged 18-80 years old;
  • a diagnosis of idiopathic or post-infective bronchiectasis was made;
  • patients had at least two exacerbations in the past year and were in a stable state for at least 4 weeks prior to the primary enrollment.

You may not qualify if:

  • Patients were excluded if they fulfilled any of the following criteria: current smokers; cigarette smoking within 6 months; cystic fibrosis or other etiologies (such as immunodeficiency, allergic bronchopulmonary aspergillosis, traction bronchiectasis caused by emphysema, advanced pulmonary fibrosis, etc.); pulmonary function test results showing a forced expiratory volume in 1 s (FEV1) ≤ 30% of the predicted value; a history of severe cardiovascular or neurological disease; comorbidity with liver disease, kidney disease, malignant tumor, gastric ulcer, or intestinal malabsorption; a known allergy to N-acetylcysteine; pregnancy or lactation (for women); a history of prior macrolide use of more than 1 week; and poor compliance.
