Oxford University and the COVID Symptom Study app are joining forces to widen access to the PRINCIPLE trial of potential treatments for COVID-19.

COVID Symptom Tracker and PRINCIPLE

The COVID Symptom Study App was developed and is managed by health technology company ZOE, with the research using data from the app being undertaken by academics at King's College London. The app has now been downloaded by over 3.5 million people in the UK and has recruited over 800,000 citizen scientists to its Vaccine and Trial Registry.

The registry was launched on 9 July and aims to raise awareness and rapidly recruit members of the public to the growing number of national and community-based clinical trials for COVID-19 in the UK.

Those users who have already signed up to the COVID Symptom Study Vaccine and Trial registry and test positive for COVID-19, or show signs of symptomatic COVID in the app, will be contacted and given the opportunity to join Oxford University’s PRINCIPLE and STOIC trials.

The PRINCIPLE Trial is evaluating whether treatment early on in the community can help people aged over 50 recover quickly from COVID-19 illness, without the need for hospital admission.

The trial, which is open across the UK to people aged over 50 with an underlying health condition or anyone aged over 65, can be easily joined online from home without face-to-face visits, or via GP practices across the country. It is one of the UK Government’s four national priority platform trials on COVID-19 treatments.

PRINCIPLE is currently evaluating azithromycin and doxycycline, which are two commonly prescribed antibiotics. These drugs are thought to have anti-viral and anti-inflammatory properties against coronavirus, and also treat bacterial infections like pneumonia, which is a common reason for deterioration in people with COVID-19. 

665 people have already signed-up to take part, but many more are needed to determine whether either of the treatments can help treat the disease. The collaboration with the COVID Symptom Study app will help to link eligible individuals with the PRINCIPLE trial. 

The partnership includes a second community study from Oxford University, the STOIC (STerOids In COVID) study, which is investigating the early use of a steroid inhaler, in people with symptoms suggestive of COVID-19, as a treatment to reduce the chance of needing to go to hospital.

Tim Spector, Professor of Genetic Epidemiology at King's College London, and lead scientist at the COVID Symptom Study app comments: 

‘We are really excited to be partnered with Oxford University. This is exactly why we set up the Vaccine and Trial Registry. We have millions of engaged loyal users, who all want to help play a role in the fight against COVID and this collaboration will help us link those individuals up with trials. Both the PRINCIPLE and the STOIC trials are conducting essential research, especially whilst we have no effective vaccine yet. This work will save lives and as always, we want to thank all our amazing users as they continue to allow us to make a real impact on COVID-19.’

Professor Chris Butler, a GP and Co-Lead of the PRINCIPLE Trial at the University of Oxford’s Nuffield Department of Primary Care Health Sciences, said: 

‘Until an effective vaccine is developed and made widely available, treating people at home who show symptoms of COVID-19 is the only way to help most people who get this awful illness to recover more quickly, and prevent those who are at most risk of serious illness from having to go to hospital. 

‘PRINCIPLE will answer a pressing question - which of the treatments showing promise against COVID-19 are effective in people at higher risk of complications early on in the illness? With the prospect of a second wave later this year, we urgently need many more people to join the trial to determine which, if any, of these drugs can be introduced into usual care. Our partnership with the COVID Symptom Study is an important step in facilitating access to this trial for those users who test positive for the disease.’
