RECOVERY Trial

The Randomised Evaluation of COVID-19 Therapy (RECOVERY Trial)[1] is a large-enrollment clinical trial of possible treatments for people in the United Kingdom admitted to hospital with severe COVID-19 infection.[2][3][4] The trial was later expanded to Indonesia, Nepal and Vietnam.[5] The trial has tested ten interventions on adults: eight repurposed drugs, one newly developed drug and convalescent plasma.[2]

Operations[edit]

The trial is run by the Nuffield Departments of Population Health and of Medicine at the University of Oxford[12][9] and supported by the National Institute for Health Research (NIHR). The study is led by Peter Horby and Martin Landray who serve as Co-Chief Investigators of the trial.[15][16] By July 2020, the trial was in progress at 176 NHS hospitals in the UK, involving many thousands of health professionals.[17]


The trial began in March 2020. As of March 2021 the trial had enrolled more than 40,000 COVID-19 participants admitted to hospitals in the UK;[7] the estimated primary completion date was December 2021, and the estimated study completion date was December 2031.[6][13]

Around a third of patients in the trial were still in hospital at the end of the 28-day trial period, so their final outcomes were not known.

As an , there are fears that dexamethasone could make the illness worse, and prolong the infection in patients where the immune system has not yet overreacted and caused inflammation.[9][29]

immunosuppressive drug

The preprint authors themselves warned that "the results are consistent with possible harm" in patients who did not require oxygen at the time of enrolment. The trial observed a 22% increase in mortality in these patients (rate ratio 1.22 [95% Confidence Interval 0.93 to 1.61]; p=0.14), though this observation may still be due to chance.[18]

[18]

Responding to the publication, the emphasized that dexamethasone should only be used for patients with severe or critical disease, under close clinical supervision, stating that "There is no evidence this drug works for patients with mild disease or as a preventative measure, and it could cause harm."[30]
