Trial summary

Persistent cough is a common symptom, accounting for about 20% of referrals to outpatient chest clinics. Most coughs are caused by self-limiting viral infections such as the common cold. However, 1 in 4 people with a viral infection develop a persistent cough, which can go on for several weeks. Read more about this study

About this study

Official title: A Double Blind Randomised Placebo Controlled Trial of Montelukast in the Treatment of Acute Persistent Cough in Young People and Adults in Primary Care

Persistent cough is a common symptom, accounting for about 20% of referrals to outpatient chest clinics. Most coughs are caused by self-limiting viral infections such as the common cold. However, 1 in 4 people with a viral infection develop a persistent cough, which can go on for several weeks. Whooping cough is a common cause of persistent cough in young people and adults. Although the whooping cough vaccine gives lifelong protection against severe infection, it does not appear to give such long-term protection against milder infections, which can make someone cough for many weeks. There are currently no proven efficacious treatments for persistent cough following either a viral infection or infection with whooping cough.

Montelukast is a medication which is already licensed for the treatment of asthma. It works by blocking the action of chemicals called leukotrienes, which make the airways of people with asthma inflamed and sensitive. There is strong evidence to suggest that leukotrienes are also involved in causing persistent cough following viral or whooping cough infection. Montelukast may therefore also help settle persistent coughs in these settings.

Over 18 months, we will recruit patients aged 16-49 years with a cough lasting 2-8 weeks from general practices in England. An oral fluid sample will be taken from each participant to be tested for whooping cough. Participants will be randomly allocated to receive a 28-day course of montelukast or placebo tablets and asked to complete a daily cough diary for two weeks. They will be assessed after two weeks by their GP (face-to-face) and after four weeks by another member of practice clinical staff (telephone). Some participants will be given a 24-hour cough monitor to wear on study entry and at two-week follow-up. This study will be funded by the National Institute for Health Research's School of Primary Care.

Secondary outcomes (11)
  1. Change in Leicester Cough Questionnaire (LCQ) physical, psychological and social domain scores at 2 and 4 weeks post randomisation.

    Measured: 2 and 4 weeks post randomisation

  2. Overall cough severity according to cough visual analogue scale (VAS) scores over the 2-week period post randomisation (area under the curve).

    Measured: 2 weeks post randomisation

  3. Paroxysmal cough severity over the 2-week period post randomisation (area under the curve).

    Measured: 2 weeks post randomisation

  4. Proportions of participants reporting cessation of cough at 2 and 4 weeks post randomisation.

    Measured: 2 and 4 weeks post randomisation

  5. Recruitment rate among young people and adults presenting with acute persistent cough.

    Measured: End of study

  6. Follow-up rates at 2 weeks and 4 weeks post randomisation.

    Measured: 2 weeks and 4 weeks post randomisation.

  7. Medication adherence rates at 2 and 4 weeks post randomisation.

    Measured: 2 and 4 weeks post randomisation

  8. Prevalence of whooping cough among participants.

    Measured: End of study

  9. Correlations between subjective cough outcome measures (diary-recorded paroxysms of cough, cough visual analogue scale score and exercise-related cough score) and objective cough frequency measured using the Leicester Cough Monitor.

    Measured: 2 and 4 weeks post randomisation

  10. Proportions of participants undergoing further intervention (re-consultation, investigation, prescription of other medication).

    Patient notes will be reviewed in this time frame

    Measured: 4 - 8 weeks

  11. Proportions of participants with adverse events.

    Measured: End of study

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Montelukast in people with Persistent Cough and Whooping Cough, run by University of Oxford at 1 site in United Kingdom.

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 8 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 10 Oct 2012. 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 United Kingdom. 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?

Results are not available in the source record.

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?

Change in Leicester Cough Questionnaire (LCQ) total score at 2 and 4 weeks post randomisation. (time frame: 2 and 4 weeks post randomisation). 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 NCT01279668, 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 10 Oct 2012.
