Study summary

Phase I: To develop and validate laboratory urine and blood test for the detection of medications commonly used in the treatment of asthma Phase II: to test the developed assay in the clinic, to determine its practicality to conduct, and its clinical utility in adherence assessment.

Read the detailed description

Phase I: laboratory based study to develop LC-MS/MS assay of urine / blood to detect presence or lack asthma medication in 50 volunteers with asthma. Phase II: once the test is validated it will be tested in a 100 patients attending the asthma clinics to test its clinical utility. Urine and blood samples will be collected from patients at time of clinic attendance to test for asthma medication panel and outcome will determine adherence or non-adherence. Clinical outcomes of adherent versus non adherent groups will be compared in terms of asthma control, lung function, biomarkers FeNO and blood eosinophils, exacerbation frequency and hospitalisation.

Study population

Patients will be identified at the BRSAS, general asthma clinics and as inpatients admitted to wards at HEFT. The research team will approach patients in these settings.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Aged 18-80
  2. Able to give valid
  3. Prescribed one or more of the medications to be tested
  4. Able to provide a blood and urine sample
  5. Able to complete questionnaires in English

Exclusion criteria

Exclusion Criteria:

  1. Females who are pregnant or lactating.
  2. Patients known to have any blood borne virus that would render the sample hazardous. This includes , and .
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

What researchers measure

Primary outcomes

  1. To develop and validate laboratory urine and blood test for the detection of medications commonly used in the treatment of asthma

    5ml biochemistry SST and 2.5ml EDTA blood sample and urine 10ml sample will be collected simultaneously from the patient on the same day and transferred to biochemistry department at Heartlands hospital. These samples will be used to develop and validate the assays

    Time frame: 4 months

Secondary outcomes

  1. To test the developed assay in the clinic, to determine its practicality to conduct, and its clinical utility in adherence assessment.

    Patients' assessment will be similar to that described in phase I, however in phase II the administration treatment will not be directly observed. Patients will be recruited from the clinic. Patients will be asked to identify the time they took their prescribed medication and asked to provide a 5ml biochemistry SST and 2.5ml EDTA blood sample and urine 10ml sample.

    Time frame: 6 months

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 11, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
