Established to test a range of potential treatments for COVID-19, the RECOVERY trial has included a comparison of colchicine, an anti-inflammatory drug that is commonly used to treat gout, vs. usual care alone. There has been no convincing evidence of the effect of colchicine on clinical outcomes in patients admitted to hospital with COVID-19, and recruitment to the colchicine arm of the RECOVERY trial has now closed. Recruitment to all other treatment arms – aspirin, baricitinib, Regeneron’s antibody cocktail, and dimethyl fumarate – continues as planned.

The Randomised Evaluation of COVID-19 Therapy (RECOVERY) trial has demonstrated that tocilizumab, an anti-inflammatory treatment, reduces the risk of death when given to hospitalised patients with severe COVID-19. The study also showed that tocilizumab shortens the time until patients are successfully discharged from hospital and reduces the need for a mechanical ventilator.
Evidence supports WHO recommendation for primaquine combined with ACTs to block Plasmodium falciparum transmission
12 February 2021
Evidence from a new study, initiated by the Primaquine Roll Out Group and conducted at WWARN, supports the World Health Organization (WHO) recommendation for use of 0.25mg/kg dose of primaquine (PQ) combined with artemisinin-based combination therapies (ACT) to block Plasmodium falciparum transmission.

Baricitinib – an anti-inflammatory treatment for rheumatoid arthritis– is being investigated in the RECOVERY trial, the world’s largest clinical trial of treatments for patients hospitalised with COVID-19, taking place in 177 hospital sites across the UK and with over 33,000 patients recruited so far. As an anti-inflammatory, baricitinib may block the signalling activity of cytokine molecules which contribute to the hyper-inflammatory state seen in severe COVID-19. It is thought that baricitinib may act also have some anti-viral activity. The other treatments currently being investigated in the RECOVERY trial are Regeneron’s antibody cocktail, Aspirin and Colchicine.
RECOVERY trial closes recruitment to convalescent plasma treatment for patients hospitalised with COVID-19
15 January 2021
Convalescent plasma has been widely used as a treatment for COVID-19 but to date there has been no convincing evidence of the effect of convalescent plasma on clinical outcomes in patients admitted to hospital with COVID-19. Recruitment to the convalescent plasma arm of the RECOVERY trial has now closed. The preliminary analysis based on 1873 reported deaths among 10,406 randomised patients shows no significant difference in the primary endpoint of 28-day mortality. Recruitment to all other treatment arms – tocilizumab, aspirin, colchicine, and Regeneron’s antibody cocktail – continues as planned.

The responsiveness of a health system is one of its goals, alongside fairness in financing and outcomes. Listening and responding to the public can make a health system stronger and fairer. However, responsiveness is likely to be undermined, especially for vulnerable and marginal populations, in periods of crises such as disease outbreaks. In the current COVID-19 crisis, there has been more focus on health system control interventions, with minimal consideration of community views. KWTRP colleagues in Kenya consider community engagement and citizens feedback channels, concerns raised by the public and how they were handled, and highlight lessons learned.
15 December 2020
Established in March 2020, the RECOVERY trial tests a range of potential treatments for COVID-19, including azithromycin, a widely used antibiotic that also reduces inflammation. The azithromycin arm of the trial was established to determine whether or not the drug has a meaningful benefit among patients hospitalised with COVID-19. A preliminary analysis shows no significant difference in the primary endpoint of 28-day mortality; there was also no evidence of beneficial effects on the risk of progression to mechanical ventilation or length of hospital stay.
1 December 2020
A new study quantifying the high risk of Plasmodium vivax parasitaemia after treatment of Plasmodium falciparum malaria aims to identify populations in which a policy of universal radical cure, combining artemisinin-based combination therapy with a hypnozoitocidal antimalarial drug, would be most beneficial.
18 November 2020
As the world anxiously awaits COVID-19 vaccines, people working in healthcare settings remain at risk of infection from COVID-19. The Pakistani arm of COPCOV, the global study to test if hydroxychloroquine or chloroquine can prevent COVID-19 in healthcare workers, has begun to enrol participants at Aga Khan University, joining sites in the UK and Thailand.
6 November 2020
Aspirin will be investigated in the world’s largest clinical trial of treatments for patients hospitalised with COVID-19. The RECOVERY trial is taking place in 176 hospital sites across the UK, and has so far recruited over 16,000 patients. Patients with COVID-19 are at higher risk of blood clots forming in their blood vessels. Platelets seem to be hyperreactive in COVID-19 and may be involved in the clotting complications. As an antiplatelet agent, aspirin may reduce the risk of blood clots in patients with COVID-19.

No clinical benefit from use of lopinavir-ritonavir in hospitalised COVID-19 patients studied in RECOVERY
29 June 2020
The RECOVERY trial was established in March as a randomised clinical trial to test a range of potential treatments for COVID-19, including lopinavir-ritonavir, an antiviral treatment commonly used to treat HIV. There was no significant difference in the primary endpoint of 28-day mortality, and the results were consistent in different subgroups of patients. There was also no evidence of beneficial effects on the risk of progression to mechanical ventilation or length of hospital stay. The trial Steering Committee concluded that there is no beneficial effect of lopinavir-ritonavir in patients hospitalised with COVID-19 and closed that treatment arm.
UK regulator gives green light to clinical trial of hydroxychloroquine to prevent Covid-19 in healthcare workers
29 June 2020
The UK regulator MHRA announced on 26 June that it would again permit recruitment to the COPCOV COVID-19 prevention clinical trial. The MHRA decision came 5 weeks after it reacted immediately to the now-discredited paper published in The Lancet suggesting harms with hydroxychloroquine, and paused recruitment of UK participants. But The Lancet paper was based on fabricated data and was swiftly retracted. After this interruption, recruitment around the globe to COPCOV can now resume.
Dexamethasone reduces death in hospitalised patients with severe respiratory complications of COVID-19
16 June 2020
The RECOVERY trial tests a range of potential treatments for COVID-19, including low-dose dexamethasone (a steroid treatment). Patients were randomised to receive dexamethasone 6 mg once per day for ten days and were compared with patients receiving usual care alone. Dexamethasone reduced deaths by one-third in ventilated patients and by one-fifth in other patients receiving oxygen only; there was no benefit among those patients who did not require respiratory support. Based on these results, 1 death would be prevented by treatment of around 8 ventilated patients or around 25 patients requiring oxygen alone.
5 June 2020
A new statement has been released from Professor Peter Horby and Professor Martin Landray, Chief Investigators of the RECOVERY Trial.
