Help find treatments for COVID-19 from home
PRINCIPLE is a UK-wide clinical study from the University of Oxford to find COVID-19 treatments for recovery at home.
We are looking for medicines that can help people with COVID-19 symptoms get better quickly and stop them needing to go to hospital. PRINCIPLE is recruiting participants through this website and also through GP practices across the UK.
PRINCIPLE is open to all with ongoing symptoms of COVID-19, regardless of vaccination status.
If you are currently experiencing COVID-19 symptoms AND have a positive test, you may be eligible to join the PRINCIPLE trial and help the search for new treatments from the comfort of your own home.
Who is eligible to join PRINCIPLE:
You are currently experiencing COVID-19 symptoms for 14 days or less.
AND: You have had a positive test for COVID-19 in the last 14 days
AND: You are aged 18 or over
We are investigating these treatments:
Favipiravir (an antiviral drug)
Ivermectin (used to treat several types of parasitic infections)
The usual standard of NHS care
How to sign-up
PRINCIPLE is entirely remote, meaning you can participate from the comfort of your own home from anywhere in the UK with no face-to-face visits required. The trial team and your own GP will be available for you to contact throughout.
If you currently have COVID-19 symptoms:
