Plain English Summary
Background and study aims
COVID-19 is an infectious disease caused by the virus SARS-CoV-2, which has spread across the world since December 2019. The effects of COVID-19 in the early stages of illness are now well known, and research projects have identified new treatments to help patients at this early stage. 1 in 10 patients die 3 months after being discharged from hospital. There is now evidence that around 20% of COVID-19 patients develop new or worsened symptoms, often involving their heart, lungs and circulation, after discharge from hospital. These symptoms are often grouped together as part of a syndrome known as “Long COVID”. Because COVID-19 is a new disease, there is still a lot that we do not know, particularly about the longer-term effects. The aim of this study is to compare different treatments that could prevent or reduce long-term symptoms in COVID-19 patients. The main objective is to determine whether the treatments used improve longer-term outcomes for COVID-19 patients.
Who can participate?
Patients who have been admitted to hospital with COVID-19
What does the study involve?
Participants will be randomly allocated to receive:
1. Apixaban, an anticoagulant or “blood thinner”, twice a day for 2 weeks or
2. Atorvastatin, a statin with anti-inflammatory properties, once a day for 12 months or
3. The usual standard care offered by their hospital, as appropriate to their symptoms and conditions
The researchers will collect a small amount of medical data from the hospital where the participant is being treated, and will also request data from routine health records held by NHS Digital or the equivalent organisations in the devolved nations. This data will be collected for 12 months from the day the participant enters the study, and may include hospital visits, GP visits, referrals, prescriptions and information about deaths.
Participants will also be invited to complete follow-up surveys. This is optional. Surveys can be completed via an app on a smartphone or tablet, or over the phone with a researcher. The surveys will be sent no more frequently than once a week, and include questions relating to symptoms, quality of life, resource use and experience of participating in research.
What are the possible benefits and risks of participating?
Apixaban and atorvastatin have been chosen because patients with Long COVID can have symptoms caused by inflammation and excess clotting. There is potential that the treatment patients are given as part of the study may improve their symptoms and help them recover from their COVID-19 illness more quickly. Though the medications used in HEAL-COVID are well-established treatments with a known profile of safety, like most medication, they also have potential side effects.
Where is the study run from?
Cambridge University Hospitals NHS Foundation Trust and The University of Cambridge jointly Sponsor this study and are responsible for managing it. They are based in the United Kingdom. They have asked that the day-to-day running of the study be carried out by a team based at the Liverpool Clinical Trials Centre (LCTC, part of the University of Liverpool).
Any hospital in the UK looking after COVID patients can take part.
When is the study starting and how long is it expected to run for?
January 2021 to January 2025
Who is funding the study?
National Institute for Health Research (NIHR) (UK)

Unfortunately, this study is not recruiting public volunteers at this time. This is because the research isn’t ready for volunteers yet or the researchers are directly identifying volunteers in certain areas or hospitals.

| Scientific title | HElping Alleviate the Longer-term consequences of COVID-19 (HEAL-COVID): a national platform trial |
| Study acronym | HEAL-COVID |
| Study hypothesis | Interventions in the post-hospital (convalescent) phase of COVID-19 improve longer-term mortality/morbidity outcomes. |
| Ethics approval(s) | Approved 07/04/2021, South Central - Berkshire Research Ethics Committee (Bristol REC Centre, Whitefriars, Level 3, Block B, Lewins Mead, Bristol, BS1 2NT, UK; +44 (0)207 104 8224, +44 (0)207 104 8270; berkshire.rec@hra.nhs.uk), REC ref: 21/SC/0121 |
| Condition | COVID-19 (SARS-CoV-2 infection) |
| Intervention | The HEAL-COVID trial is an adaptive platform trial that will enrol patients at the point of hospital discharge from centres across the UK. This study will test different treatments among adult patients hospitalised with COVID-19 disease, to investigate whether these treatments can prevent or treat the longer-term symptoms of COVID-19. Many patients experience new or worsened symptoms after their acute COVID-19 illness, including thrombosis, fibrosis and inflammation, often described as the ill-defined syndrome “Long COVID”. The rationale is that early intervention post-hospitalisation may reduce morbidity and mortality, reduce symptom burden for patients and improve their quality of life. Patients will be recruited in hospital but treatment will commence on discharge. Two treatments will be examined initially (Apixaban and Atorvastatin), with new treatments to be added via substantial amendments at the direction of the UKCTAP. These treatments have been chosen due to their proven histories as a safe and effective anticoagulant (blood thinner) and anti-inflammatory. Each treatment arm (initially apixaban and atorvastatin) will be compared to the ‘standard care’ arm, with the null hypothesis that there is no difference in outcome between the treatments. 877 participants are required for each treatment arm. The control arm is ‘standard care’ because there are no known treatments that influence outcomes in COVID-19 disease. All participants in the trial will receive the best available standard care available for any long-term symptoms they develop. The control arm is shared so that more patients receive experimental treatments, and the randomisation system includes the capability to exclude patients from one treatment arm only if they do not meet the treatment specific exclusion criteria (e.g. hypersensitivity to the drug). A randomised controlled platform trial design has been chosen as it is the most reliable way to assess the effects of treatment. The design is adaptable in order to allow a broad range of patients to be enrolled in large numbers, with treatment arms to be added or removed. The trial is not blinded and there is no placebo because it is not practical to blind in a multi-arm platform trial and it would add significant complexity to a trial that will need to operate in a very busy clinical environment. It is also not necessary as the primary outcome is hospital-free survival. Participants will be recruited shortly before discharge from hospital for their initial COVID-19 admission. They will receive the study treatments by prescription from a doctor or prescribing nurse as part of their routine care. There are no follow-up visits, with primary outcome data being sought from NHS Digital (and the equivalent organisations in Scotland, Wales & Northern Ireland). Secondary outcome data including resource use and patient-reported symptoms/quality of life will be collected via questionnaires completed via a smartphone application or over the phone. EQ5D-5L and resource use questionnaires will be completed monthly. The timing of the other patient-reported questionnaires will be determined by randomisation (either 1:weekly for 4 weeks then monthly or 2:weekly for 12 weeks then monthly). It is intended that all patients admitted to hospital with COVID-19 who meet the eligibility criteria will be invited to participate Patient groups have been involved in the development of study materials, including the patient information sheet, poster, website content and survey frequency design. It is intended that results be published as soon as possible when any treatment arm is removed, either due to clear efficacy or a clear indication that the treatment is no better than standard care. Interim analyses will take place on a regular basis, with an Independent Data & Safety Monitoring Committee meeting monthly to review preliminary data and make recommendations about trial progress. The results from this study have the potential to change standard care for post-hospital COVID-19 patients as there are currently no known treatments. As such the publication of these results in a timely manner is a priority. |
