New Study Testing the Delivery of the Best Asthma Treatment Based on Genetics

New Study Testing the Delivery of the Best Asthma Treatment Based on Genetics

 A study by researchers from across the UK is aiming to discover whether treating asthmatic children according to their genetic status can improve their quality of life by reducing hospitalisations, missed school days and other problems caused by the disease.

Previous studies have shown that 100,000 young people are routinely given an asthma controller medication called salmeterol, which has no effect on some of the patients it is prescribed for. Young volunteers are now being sought for the Personalised Medicine for Asthma Control (PACT) study which is funded by children's charity Action Medical Research. This study has been developed by researchers at Brighton and Sussex Medical School (BSMS), working alongside colleagues from the Universities of Dundee, Aberdeen, Queen Mary Univeristy of London and General Practitioners.

Children and young adults with asthma are being asked to join the study to see whether they respond better to a personalised approach to asthma treatment than to current standard treatments. PACT is looking to involve young people aged between 12 - 18 years with asthma.

One of the first participants to sign up was Molly Lynch, from Chichester. Molly was 11 when she was first diagnosed with asthma following a bout of pneumonia two years ago. Having previously suffered no respiratory problems she now needed an inhaler to control her asthma, experienced wheezing and feelings of being tight-chested. Of greatest concern were the coughing fits Molly experienced each morning and which could go on for an hour at a time.

Molly's mother Sarah heard about the PACT trial during a visit to their GP surgery. Molly agreed to take part and was randomised to a personalised medicine group. As a result of the personalised treatment she recieved, Molly's asthma improved significantly. All her symptoms have reduced, her Peak Flow Meter readings have improved and she now enjoys some mornings without coughing.

"We signed up for the trial because Molly had been diagnosed quite late and she went from a situation where she was fine to one where she was struggling," explained Sarah. "The cough was particularly extreme but Molly's asthma has improved a lot since she joined the trial. Personalised treatment has really helped and shown that she was obviously on the wrong medication before. I would encourage anyone who fits the study criteria to take part."

Professor Somnath Mukhopadhyay, Chair of Paediatrics at BSMS, said "Our research has previously found that 15% of children and young adults have a particular gene variation that is linked to poor asthma control with this treatment. That's why we are investigating whether young people's genetic make-up should be taken into account when deciding whether to give them the routinely-used salmeterol, or an alternative medication called montelukast."

Professor Mukhopadhyay said not receiving effective treatment for asthma results in more school absences and more emergency visits to the GP or hospital. Long term, this poor asthma control could have an impact on their education and future job prospects.

All new participants will be asked to provide a saliva sample in order to find out their genetic status. Up to half of the participants will be prescribed an asthma add-controller medication according to their gene test results, and the others will be given standard treatment without knowledge of their gene test, as is currently the case.

The participants will report from home online by completing questionnaires about their quality of life at 3, 9 and 12 months after commencing the study. This new method of collecting research data will avoid the need for hospital visits for children and young people, save costs and will show whether the personalised approach improves life quality. At the end of the study, all participants and their GPs will be given the results of their gene test and a summary of the study results.

Young people aged 12-18 years with asthma, parents of a young person with asthma, and healthcare professionals caring for patients with asthma can find out more about the study at or by calling the Tayside Clinical Trials Unit on 01382 383932.
