Research summary 

There are a number of possible treatments for COVID-19 infection available. The Randomised Evaluation of COVID Therapy (RECOVERY) trial will test whether these treatments work better than the treatments that are given in hospital at the moment. As well as normal hospital treatment patients with COVID-19 infection will either receive no additional experimental treatment, or will receive one of the following treatments:

  •  a combination of Lopinavir-Ritonavir (antiviral drugs)
  • interferon β1b (used to treat some kinds of multiple sclerosis)
  • low-dose corticosteroids (used to reduce inflammation)
  • hydroxychloroquine (similar to a drug used to treat malaria).

The trial is designed so that it can also test other possible treatments as they become available.

Information on time in hospital, the number of deaths in hospital, and the need for artificial ventilation will be collected.  The study hopes to identify effective treatments within three months. Information is available at
