E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To show that both treatments with NAC 600 mg/day and NAC 1,200 mg/day exhibit a superior efficacy, in terms of reduction of the composite score Breathlessness, Cough and Sputum Scale versus placebo in patients with COPD exacerbation. |
|
E.2.2 | Secondary objectives of the trial |
1.To evaluate a dose escalation effect for doses of 600 and 1,200 mg/day of NAC in reducing composite score in patients with COPD exacerbation. In the treatment groups 2.To compare the time for remission of symptoms and the number of recovered patients. 3.To compare the number of sleep awakenings due to cough. 4.to compare the consumptions of medications prescribed for COPD exacerbation 5.To compare the number of patients with hospitalizations for COPD. 6.To compare the change from baseline of FEV1 and FEV6. 7.To compare the change from baseline of the patient s well-being. 8.To evaluate the safety of the treatment with NAC 600 mg/day and NAC 1,200 mg/day in terms of incidence of adverse events. 9.To evaluate the global efficacy and tolerability of the treatment with NAC 600 mg/day and NAC 1,200 mg/day. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint is the change from baseline in the composite score at day 5 of treatment, by summing up single breathlessness, cough and sputum scores, assessed daily by the patient on a 5-point scale NAC doses 600 mg/day and 1200mg/day are compared to placebo |
