About this study
Official title: Efficacy and Safety Study of Acetylcysteine/Doxofylline 1200/400 mg Effervescent Tablet in the Treatment of Moderate-Severe Chronic Obstructive Pulmonary Disease (COPD)
The objective is to assess efficacy and safety of Acetylcysteine/Doxofylline 1200/400 mg Effervescent Tablet once daily treatment besides standard/usual treatment, as compared with placebo once daily in patients with stable moderate to severe COPD.
Read the detailed description
The objective is to assess efficacy and safety of Acetylcysteine/Doxofylline 1200/400 mg Effervescent Tablet once daily treatment besides standard/usual treatment, as compared with placebo once daily in patients with stable moderate to severe COPD.
Patients who met all inclusion criteria will be randomized to receive double-blind treatment with Acetylcysteine/Doxofylline 1200/400 mg Effervescent Tablet once daily (n = 35) or placebo (n = 35) once daily for 4 weeks.
Patients will be evaluated at 2 consecutive visits: screening \& treatment visit (first visit) and after treatment visit (second visit).
Spirometric measurements will be performed at pre-treatment during the first visit and post-treatment at two different time points (23 hr + 15 min and 23 hr + 45 min) during the second visit. The average of the values at 23 hr 15 min and 23 hr 45 min during the second visit will be defined as trough value.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Acetylcysteine/Doxofylline in people with COPD, run by Neutec Ar-Ge San ve Tic A.Ş at 2 sites in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Jun 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Mean changes in Breathlessness, Cough, and Sputum Scale (BCSS) score from baseline (time frame: 4 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jun 2020; AzTrials last refreshed its copy on 8 Nov 2026.
