Plain English Summary

Background and study aims
Chronic lung allograft dysfunction (CLAD) is a complication that can happen after a lung transplant. CLAD develops when the immune system causes damage to the transplanted lungs, and lung function drops. It is also called chronic rejection. E-CLAD UK is a research study that aims to find out if a therapy called extracorporeal photopheresis (ECP) treatment can be used to treat CLAD. The research is being done by a team of specialists from all five UK adult lung transplant centres. ECP is currently used to treat various conditions involving the immune system. There have been a few small studies that suggest ECP could also help in the treatment of CLAD. However, there is currently not enough evidence for the NHS to say whether or not it should be used routinely to treat CLAD. The E-CLAD UK trial has been set up to answer this question.

Who can participate?
Double lung or heart and double lung transplant recipients aged 16 years and over with a confirmed diagnosis of CLAD.

What does the study involve?
The trial will involve 90 patients, who will all receive usual care for CLAD for 24 weeks. On top of that, half of these patients will also receive a course of ECP treatment. A course of ECP therapy involves 9 cycles of ECP treatment, every 2 weeks for 12 weeks and then 4 weekly until week 20. Each cycle involves 2 treatments, lasting between 2-3 hours on consecutive days. Both groups will continue all their routine clinic appointments with their transplant team.

What are the possible benefits and risks of participating?
The researchers can’t promise that taking part in this trial will benefit participants directly, although there is the possibility that the allocated treatments (either standard care or ECP) may help to treat CLAD. It is hoped that the information we get from this trial will help improve treatment for patients with CLAD in the future.
There are always risks with undergoing any trial procedure and all medical treatments can lead to side effects. The research team will monitor participants’ health regularly to ensure their wellbeing. The main known side effect of ECP is that it will temporarily make patients more sensitive to sunlight, meaning that they will have to take extra care of the sun for at least 24 hours after treatment. Other side effects can include tiredness, dizziness, feeling cold and a mildly raised temperature for a short time following treatment.

Scientific titleExtracorporeal photopheresis in the treatment of chronic lung allograft dysfunction: a randomised controlled trial
Study acronymE-CLAD UK
Study hypothesisPrimary objective:
To determine if extracorporeal photopheresis (ECP) therapy plus standard of care (SOC) is more effective at stabilising lung function in lung transplant recipients with chronic lung allograft dysfunction (CLAD) compared to SOC alone.

Secondary objectives:
1 To determine how the treatment strategies of ECP therapy plus SOC and SOC alone affect the following outcomes over a 24-week period
2. Change in rate of decline in lung allograft function between 12 weeks before (available from clinical records) and 24 weeks after randomisation, measured by change in forced expiratory volume in one second (FEV1) and forced vital capacity (FVC)
3. Absolute change in lung allograft dysfunction from baseline to 24 weeks, measured by FEV1 and FVC
4. Change in exercise capacity from baseline to 24 weeks measured by 6-minute walk test
5. Change in disease severity from baseline to 24 weeks measured by International Society for Heart and Lung Transplantation (ISHLT) CLAD Stage (1-4)
6. Change in health-related quality of life from baseline to 24 weeks measured by SF-36 v2 and EQ-5D-5L
7. Survival at 24 weeks after randomisation (end of study)
8. AEs and serious adverse events (SAEs) from randomisation to 24 weeks
Ethics approval(s)Approved 17/10/2022, East Midlands - Derby Research Ethics Committee (Equinox House, City Link, Nottingham, NG2 4LA, UK; +44 (0)207 1048210; derby.rec@hra.nhs.uk), ref: 22/EM/0218
ConditionChronic lung allograft dysfunction
InterventionParticipants will be randomly allocated by a computer (Sealed Envelope) to one of two groups. One group will receive the current usual treatment for CLAD, and the other group will receive extracorporeal photopheresis (ECP) in addition to the current usual treatment. ECP involves the temporary removal of blood through a machine where white blood cells are separated, combined with a drug which makes them sensitive to ultraviolet light and then exposed to ultraviolet A light causing them to shut down before being returned to the bloodstream. ECP treatment will involve a course of up to 9 treatment cycles over a 20-week period with each cycle consisting of 2 individual treatments lasting 2-3 hours given on consecutive days. All participants will be closely monitored over a 24-week period.
