About this study

Official title: The Efficacy of Budesonide/Formoterol in Cough Variant Asthma -- A Multi-center Randomized, Controlled Clinical Trial

Cough variant asthma (CVA), subtype of bronchial asthma, is considered to be one of the most common causes of chronic cough in different cough guidelines of United States, Europe, China and other countries. From a multicenter survey in China, over one third of chronic cough is caused by CVA, which is higher than western countries. CVA differs from classic asthma, usually manifesting a symptom of only coughing without wheezing or dyspnea and particularly coughing at night. With less clinical manifestation and medical intervention, CVA patients are easily be neglected and misdiagnosed, and 30-40% of them will develop to typical asthma in the next few years. Currently there's no specific therapy recommendation for CVA in GINA. Although cough guidelines in China recommend that CVA patients should be treated as typical asthma, no recommendation on details about ICS/LABA dosage and duration. There are only a few sporadic CVA therapy researches with small sample size. Two studiesfound that CVA patients can't get cough symptom relief even after treating by low dose of ICS/LABA for 3 months. Some patients' cough symptom relapses during the 24-week follow-up phase after treating by ICS/LABA for 3 months. Overall, the best treatment of CVA is not yet clear.

GINA 2018 emphasize that asthma need long-term management. Euro-SMART study found that budesonide/formoterol 2 inhalation twice daily plus as needed can reduce daytime asthma symptoms and night-time awakenings, as well as reduce exacerbation risk more than 1 inhalation twice daily. Based on the above reasons, We assume that increase the dosage of ICS/LABA can decrease relapse rate in CVA patients with severe cough. This multi-center, randomized, controlled clinical trial can help to clarify the best dosage of budesonide/formoterol of CVA in China.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. the proportion of CVA patient with symptom relapse

    Relapse rate during the 6-months' follow-up phase after treating by different doses of budesonide/formoterol for 3 months.

    Measured: during 6-months' follow-up phase

Secondary outcomes (1)
  1. the proportion of CVA patient with symptom relief

    symptom relief rate after treating by different doses of budesonide/formoterol for 3 months.

    Measured: after treating by different doses of budesonide/formoterol for 3 months.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing budesonide/formoterol in people with Cough Variant Asthma, run by Second Affiliated Hospital, Zhejiang University, School of Medicine 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 3 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 12 May 2020. 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. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Wen Li, Prof. (86-571-87783570, liwenzjhz0408@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

the proportion of CVA patient with symptom relapse (time frame: during 6-months' follow-up phase). 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 May 2020.
