Asthma Clinical Trial - Low Exhaled NO & ICS in Suspected Asthma

Status Not yet recruiting

Clinical Trial Summary

The purpose of this study is to determine whether a low exhaled nitric oxide reading (<27ppb) is a good predictor of a negative response to inhaled steroid treatment for patients with symptoms suggestive of asthma.

Clinical Trial Description

At the first visit, which will take place at either at the GP surgery or the Nottingham Respiratory Research Unit (NRRU) informed written consent for the study will be obtained. The patients will then have an exhaled NO measurement, spirometry, venepuncture (for Full Blood Count and research blood - if consent obtained) taken and complete an Asthma Control Questionnaire (ACQ), Medical Research Council dyspnoea scale (MRC) and Leicester Cough Questionnaire (LCQ). All procedures will be carried out by the NRRU research nurse.

The investigators may use the NRRU existing database of research volunteers to recruit as necessary and also the respiratory clinics held at the NUH. If patients from clinics are recruited they will be initially approached by their usual care doctor and an information sheet will be sent / given to them accordingly.

If all the inclusion criteria are met and none of the exclusion criteria, the patients will be randomised to receive either a placebo inhaler, to be taken one puff twice daily, or a low dose inhaled steroid treatment, Budesonide 200mcgs via Turbuhaler one puff twice daily, for 3 months. Dr Tim Harrison will be prescribing the inhalers and they will be dispensed from the Nottingham City Hospital Clinical Trials Pharmacy and delivered/given to the patient by the research nurses.

Participants will be asked to return for follow up visits at 4 weeks, 8 weeks and 12 weeks following randomisation. At these follow up visits, exhaled NO, spirometry and the 3 questionnaires will be repeated. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
