About this study

Official title: A 52-week Multicenter, Randomized, Double-blind, Placebo-controlled, Prospective Study to Evaluate the Efficacy and Safety of Arbidol in Reducing the Frequency of AECOPD.

Chronic Obstructive Pulmonary Disease (COPD) is currently the fourth leading cause of death in the world. Acute exacerbations of COPD (AECOPD) are the most important events in the course of the disease because they negatively impact health status, life quality, disease progression, patients survival and economic and social burden. Reducing frequency of AECOPD is the key goal of management for COPD. Since respiratory viral infections are the mainly trigger of AECOPD, anti-viral therapy would be the affective method to prevent the exacerbation or reduce the attack severity. However, there are no positive study results of treating or preventing AECOPD used by current anti-viral drugs approved by FDA so far.

Arbidol is a non-nucleoside antiviral drug. It inhibits viral DNA and RNA synthesis by inhibiting fusion of viral lipid vesicle membrane with host cell membranes. Arbidol has broad-spectrum antiviral activity. In addition to inhibition of influenza virus, it against a variety of viruses including respiratory syncytial disease (RSV), parainfluenza virus, human rhinovirus, coxsackie virus (CV), adenovirus (ADV) and so on. In recent years, some fundamental and clinical researches have shown that arbidol has a significant role in prevention and treatment of influenza virus and other acute respiratory viral infections. Therefore, the investigators speculate that Arbidol will effectively control COPD combined with upper respiratory virus infection, thereby reducing acute exacerbations of COPD.

This is a prospective, multicenter, randomized, double-blind, placebo-controlled, 52-week study. The purpose of this study is to evaluate the efficacy and safety of arbidol in improving the frequency and extent of moderate or severe acute exacerbations in patients with COPD. Eligible subjects will be randomly assigned to treatment group or placebo group at a 2:1 ratio. Subjects of treatment group receive an on-demand arbidol 200 mg three times per day while placebo group receives matched placebo. When the subject has a new respiratory infection, original respiratory symptoms worsen, or fever (the lower body temperature is greater than 37.3℃), oral medication is given immediately. The subjects are required to receive the first dose of drug within 8 hours after the symptoms of upper respiratory tract infection.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Arbidol in people with COPD Patients, run by Shengjing Hospital at 1 site in China.

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 8 inclusion and 11 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 20 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. 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?

Frequency of moderate or severe acute exacerbation in patients with chronic obstructive pulmonary disease (time frame: 52 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03851991, which also lists 3 linked publications.

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 20 Jul 2025.
