Plain English Summary

Background and study aims
COVID-19 is a condition caused by the coronavirus (called SARS-CoV-2) that was first identified in late 2019. This virus can infect the respiratory (breathing) system. Some people do not have symptoms but can carry the virus and pass it on to others. People who have developed the condition may develop a fever and/or a continuous cough among other symptoms. This can develop into pneumonia. Pneumonia is a chest infection where the small air pockets of the lungs, called alveoli, fill with liquid and make it more difficult to breathe.

In 2020, the virus has spread to many countries around the world and neither a vaccine against the virus or specific treatment for COVID-19 has yet been developed. As of March 2020, it is advised that people minimize travel and social contact, and regularly wash their hands to reduce the spread of the virus.

Groups who are at a higher risk from infection with the virus, and therefore of developing COVID-19, include people aged over 70 years, people who have long-term health conditions (such as asthma or diabetes), people who have a weakened immune system and people who are pregnant. People in these groups, and people who might come into contact with them, can reduce this risk by following the up-to-date advice to reduce the spread of the virus.

The key clinical feature is rapid respiratory failure requiring mechanical ventilation (MV). There are no known treatments for COVID-19. The most vulnerable in society may not survive or be suitable for MV. The pandemic is overwhelming health systems across the globe and has the potential to devastate regions of the world with poor public health and underdeveloped critical care. The anticipated scale of the epidemic is such that hospitals, and particularly intensive care facilities, may be massively overstretched and overwhelmed.

This study aims to support the re-purposing of promising pharmaceutical assets with prior use in humans through performing rapid experimental medicine feasibility studies in small groups of COVID-19 patients. The results of these studies will support further evaluation in existing national and international trial networks. The key interception is to prevent the lung damage in patients with COVID-19 that leads to respiratory failure.

Who can participate?
Patients aged 16 years or above who are COVID-19 positive.

What does the study involve?
Two treatments will be compared to standard care. Nafamostat (anti-viral and anti-coagulant) given for 7 days and TD139 (galectin 3 inhibitor) given for 14 days. Participants will be placed into groups randomly.

What are the possible benefits and risks of participating?
Benefits - There is no direct benefit. However, we believe the results of this research may bring potential benefits for similar patients in the future.
Risks - Blood sampling carries a small risk of bruising and discomfort, our doctors and nurses are very experienced in taking blood and will attempt to minimise this. If possible, the research team will use an existing line to minimise any discomfort.
Collecting samples from the throat and nasal passages can be a bit uncomfortable, this will be done as smoothly as possible and by doctors and nurses experienced in obtaining these samples.
All participants randomised to a treatment will be observed carefully for any side effects; however, there may be potential side-effects that have not previously been seen. These side effects may be mild or serious. Although the team do not anticipate this, in some cases, these side effects might be long lasting or permanent and may even be life threatening. If any negative change in the health of the patient is seen which may have an association with the treatment, the team will stop the treatment.
This trial will also involve up to two chest x-rays and CT scans. The scan of your heart and lungs are additional to those that would normally be taken. The scan uses ionising radiation to form images of the body. Ionising radiation can cause cell damage that may, after many years or decades, turn cancerous. In patients with COVID-19, the chance of this happening is extremely small.

Study acronymDEFINE
Study hypothesisThis trial aims to support the repurposing of promising therapeutic assets with prior use in humans but without prior information on use in COVID-19, to determine the PK-PD profile of the agent, compared to standard of care supportive therapy, in small cohorts of COVID-19 patients. The results are intended to provide initial safety, pharmacokinetic and pharmacodynamic data and experimental medicine data to support further evaluation in existing national and international trial networks for candidates demonstrating appropriate impact on the dynamic marker of interest. The key interception is to mitigate the lung damage in patients with COVID-19 that leads to respiratory failure. As such, the assets in this programme will focus on abrogating putative mechanisms implicated in COVID-19 respiratory disease.
Ethics approval(s)Approved 03/07/2020, Scotland A REC (2nd Floor Waverley Gate, 2-4 Waterloo Place, Edinburgh, EH1 3EG, UK; +44 (0)131 4655678; manx.neill@nhslothian.scot.nhs.uk), ref: 20/SS/0066
ConditionPrevention of lung injury in patients with COVID-19 (SARS-CoV-2 infection)
InterventionCurrent interventions as of 09/09/2021, updated 22/09/2022:

Appendix 1 and 2 Interventions:
Patients will be divided into cohorts, a) community b) hospitalised requiring supplemental oxygen and c) hospitalised requiring assisted ventilation.

Two treatments will be compared to standard care. Nafamostat (anti-viral and anti-coagulant) and TD139 (galectin 3 inhibitor). For Nafamostat, it is intended that the licensed dose (0.2 mg/kg/h) in Japan will be used. Patients randomised to Nafamostat will receive a continuous intravenous infusion at 0.2 mg/kg/h for 7 days. If a participant is discharged from hospital or can no longer receive this treatment, the treatment will be stopped. For TD139, patients will inhale 5 mg x 2 (10 mg) twice daily for the first 48 h and then subsequently 5 mg x 2 (10 mg) once daily for the remaining 12 days. Unless a participant is discharged from hospital or can no longer use an inhaler – in which case treatment will be stopped at such time.

Randomisation will be performed using a web-based randomisation system (built in REDCap) hosted at the Edinburgh Clinical Trials Unit (ECTU) at the University of Edinburgh (a fully registered UKCRC CTU (registration #15)). Since these studies are designed to be small, this study will balance underlying risk across the allocations using the method of minimisation.

Follow up will be at 30, 60 and 90 days post treatment.

Appendix 3 Interventions:
Opened to recruitment Sep2022.

Appendix 3 will recruit participants satisfying cohort 2C (of the platform) - Confirmed COVID-19 positive patients with an oxygen saturation of 92% or above.
Appendix 3 of the DEFINE platform trial is not randomised, all recruited participants will receive the intervention (ATIMP).

11 participants (to a maximum of 20 participants) who have tested positive for SARS-CoV-2 within the last 2 weeks (within last 10 days at the point of screening) will receive an infusion of HLA matched SARS-CoV-2 Virus Specific T-cells (VST). The infusion will be administered in increasing doses, with the first 3 participants receiving the lowest dose (Total target cell dose = 1.5x10^6 cells), next 3 participants will receive the middle dose (Total target cell dose = 15x10^6 cells) and the last five participants will receive the highest dose (Total target cell dose = 150x10^6 cells) of VSTs. Participants will remain in hospital for a minimum of 48 hours following completion of the infusion. Follow up visits will be carried out up to and including day 7 post infusion for the period of time the participant remains in hospital. If discharged before day 7 the participant will attend the research clinic, or be offered a home visit, to carry out a day 7 follow up visit. Subsequent follow up visits will be carried out on day 14 (a telephone call), day 21 (a clinic or home visit) and 6 weeks (a telephone call) post infusion.
