Plain English Summary
Background and study aims
In early 2020, as this study was being developed, there were no approved treatments for COVID-19, a disease caused by the novel coronavirus SARS-CoV-2 that emerged in China in late 2019. The UK New and Emerging Respiratory Virus Threats Advisory Group (NERVTAG) advised that several possible treatments should be evaluated, including lopinavir + ritonavir, low-dose corticosteroids and hydroxychloroquine (which has now been done). A World Health Organization (WHO) expert group issued broadly similar advice. These groups also advised that other treatments will soon emerge that require evaluation. Since then, progress in COVID-19 treatment has highlighted the need for better evidence for the treatment of pneumonia caused by other pathogens, such as influenza and bacteria, for which therapies are widely used without good evidence of benefit or safety.
This study is comparing several different treatments that may be useful for patients hospitalised with pneumonia caused by COVID-19, influenza or other organisms. RECOVERY is a platform trial which is able to compare multiple treatments at the same time using a single protocol. This type of trial allows new treatments to be added, and treatments that are ineffective to be dropped, throughout the course of the trial.
Who can participate?
Patients may be included in this study if they have one of the following diagnoses and are in hospital:
a) Confirmed SARS-CoV-2 infection
b) Confirmed influenza A or B infection
c) Community-acquired pneumonia with planned antibiotic treatment (excluding patients with suspected or confirmed SARS-CoV-2, influenza, active pulmonary tuberculosis or Pneumocystis jirovecii pneumonia)
Patients will not be included if the attending doctor thinks there is a particular reason why none of the study treatments are suitable.
What does the study involve?
If a patient decides to join, they will be asked to sign the consent form (for children, their parent/guardian will sign the consent form). Next, brief details identifying them and answering a few questions about their health and medical conditions will be entered into a computer. The computer will then allocate them at random (like rolling a dice) to one of the possible treatment options. Neither patients nor their doctors can choose which of these options will be allocated. In all cases, treatment will include the usual standard of care for the hospital.
Please see the trial website https://www.recoverytrial.net/ for details of the current study treatments.
What are the possible benefits and risks of participating?
The study treatment may or may not help patients personally, but this study should help future patients.
Some of the treatments being investigated may cause side effects from mild issues such as an upset tummy to more unlikely severe allergic reactions. All participants will be given information about possible risks in the Participant Information Sheet. This information is also available on our website at https://www.recoverytrial.net/study-faq.
Patients should ask their hospital doctor if they would like more information.
Once included in the study, patients and their doctors will know which treatment the computer has allocated for them. Doctors will be aware of whether there are any particular side effects that they should look out for.
Women who are pregnant may be included, however, the effect of some of the treatments on unborn babies is not known. Pregnant women will not be eligible to receive some of the available treatments as they may be harmful in pregnancy or when breast-feeding. Nearly all the available treatments have previously been used in pregnancy for other medical conditions without safety concerns being raised. Where a treatment has not been given to a pregnant woman before, as a precaution we advise that women who are not pregnant, should not get pregnant within 3 months of the completion of the trial treatment(s).
Where is the study run from?
The study is being conducted by researchers at the University of Oxford (UK), working with doctors at many hospitals across the UK and other countries.
When is the study starting and how long is it expected to run for?
The study started in March 2020. Funding is in place for recruitment to continue until June 2026 (although funding for some comparisons may end earlier).
Who is funding the study?
This study is supported by grants to the University of Oxford from UK Research and Innovation (UKRI)/National Institute for Health Research (NIHR) and the Wellcome Trust, Flu Lab, and by core funding provided by NIHR Oxford Biomedical Research Centre, the Wellcome Trust, the Bill and Melinda Gates Foundation, the UK Foreign, Commonwealth and Development Office (FCDO, formerly the Department for International Development [DfID]), Health Data Research UK, the NIHR Health Protection Research Unit in Emerging and Zoonotic Infections, the Medical Research Council Population Health Research Unit, and NIHR Clinical Trials Unit Support Funding.

Intervention
Current interventions as of 04/12/2023:
RECOVERY is a randomised trial among people hospitalised for pneumonia. Eligible patients are randomly allocated between several treatment arms, each to be given in addition to the usual standard of care in the participating hospital. For patients for whom not all the trial arms are appropriate or at locations where not all are available, randomisation will be between fewer arms.
RECOVERY has an adaptive trial design. The interim trial results are monitored by an independent Data Monitoring Committee (DMC). The DMC will assess whether the randomised comparisons in the study have provided evidence that is strong enough (with a range of uncertainty around the results that is narrow enough) to affect national and global treatment strategies. In such a circumstance, the DMC will inform the Trial Steering Committee who will make the results available to the public and amend the trial arms accordingly. New trial arms can be added as evidence emerges that other candidate therapeutics should be evaluated.

Previous intervention as of 21/10/2021:
RECOVERY is a randomised trial among people hospitalised for COVID-19. Eligible patients are randomly allocated between several treatment arms, each to be given in addition to the usual standard of care in the participating hospital. For patients for whom not all the trial arms are appropriate or at locations where not all are available, randomisation will be between fewer arms.
RECOVERY has an adaptive trial design. The interim trial results will be monitored by an independent Data Monitoring Committee (DMC). The DMC will assess whether the randomised comparisons in the study have provided evidence on mortality that is strong enough (with a range of uncertainty around the results that is narrow enough) to affect national and global treatment strategies. In such a circumstance, the DMC will inform the Trial Steering Committee who will make the results available to the public and amend the trial arms accordingly. New trial arms can be added as evidence emerges that other candidate therapeutics should be evaluated.

Previous intervention as of 09/11/2020:
RECOVERY is a randomised trial among people hospitalised for COVID-19. Eligible patients are randomly allocated between several treatment arms, each to be given in addition to the usual standard of care in the participating hospital: No additional treatment vs corticosteroids (for children only) vs azithromycin vs intravenous immunoglobulin (children only). In a factorial design, eligible patients are allocated simultaneously to no additional treatment vs convalescent plasma vs synthetic neutralising antibodies. Separately, all participants aged 18 years or older will be allocated to no additional treatment vs aspirin. The study allows a subsequent randomisation for patients with progressive COVID-19 (evidence of hypoxia [or in children a hyper-inflammatory state] and raised inflammatory markers): No additional treatment vs tocilizumab. For patients for whom not all the trial arms are appropriate or at locations where not all are available, randomisation will be between fewer arms.
RECOVERY has an adaptive trial design. The interim trial results will be monitored by an independent Data Monitoring Committee (DMC). The DMC will assess whether the randomised comparisons in the study have provided evidence on mortality that is strong enough (with a range of uncertainty around the results that is narrow enough) to affect national and global treatment strategies. In such a circumstance, the DMC will inform the Trial Steering Committee who will make the results available to the public and amend the trial arms accordingly. New trial arms can be added as evidence emerges that other candidate therapeutics should be evaluated.

Participant inclusion criteria
Current inclusion criteria as of 04/12/2023:
Patients are eligible for the study if all of the following are true:
(i) Hospitalised
(ii) Pneumonia syndrome
In general, pneumonia should be suspected when a patient presents with:
a) typical symptoms of a new respiratory tract infection (e.g. influenza-like illness with fever and muscle pain, or respiratory illness with cough and shortness of breath); and
b) objective evidence of acute lung disease (e.g. consolidation or ground-glass shadowing on X-ray or CT, hypoxia, or compatible clinical examination); and
c) alternative causes have been considered unlikely or excluded (e.g. heart failure).
However, the diagnosis remains a clinical one based on the opinion of the managing doctor (the above criteria are just a guide).
(iii) One of the following diagnoses:
a) Confirmed SARS-CoV-2 infection (including patients with influenza co-infection)
b) Confirmed influenza A or B infection (including patients with SARS-CoV-2 co-infection)
c) Community-acquired pneumonia with planned antibiotic treatment (excluding patients with suspected or confirmed SARS-CoV-2, influenza, active pulmonary tuberculosis or Pneumocystis jirovecii pneumonia)
(iv) No medical history that might, in the opinion of the attending clinician, put the patient at significant risk if he/she were to participate in the trial

Participant exclusion criteria
Current exclusion criteria as of 04/12/2023:
Participants will be excluded if the attending clinician believes that there is a specific contra-indication to one of the active drug treatment arms (see Protocol Appendix 2; section 8.2, Appendix 3; section 8.3 for children, and Appendix 4 for pregnant and breastfeeding women), or that the patient should definitely be receiving one of the active drug treatment arms then that arm will not be available for randomisation for that patient. For patients who lack capacity, an advanced directive or behaviour that clearly indicates that they would not wish to participate in the trial would be considered sufficient reason to exclude them from the trial.
