Plain English summary of protocol

Background and study aims
In patients with a leg or foot ulcer, healthcare professionals use wound dressings to help manage their symptoms and heal the ulcer. Dressings can help reduce the risk of infection and aid in wound healing. This study aims to compare the effectiveness of a relatively new wound dressing product with current standard care. This product is called MedCu; it is a dressing that contains copper ions. Copper has been shown to be antimicrobial (it can kill bacteria) and there is also some evidence that it may aid with wound healing. However, more evidence is needed to demonstrate whether this is the case in an NHS care setting. The MedCu dressing will be compared to standard usual care. In most patients this will be a ‘standard’ dressing but it may also involve treatment with another antimicrobial dressing (if clinically indicated). By randomising patients to two different treatment groups, an overview can be obtained of the relative effectiveness of MedCu dressing.

Who can participate?
Adult patients (aged 18 years or over, and women of non-childbearing potential) with a foot or leg ulcer of a size between 1 and 30 cm2. The ulcer can have been present for more than 30 days to less than 1 year from the patient becoming aware of the wound in question.

What does the study involve?
The study involves patients being seen at weeks 0, 4, 8 and 12. At week 0 patients are randomly allocated to either standard care (control patients) or treatment with MedCu copper-impregnated wound dressings for the management of their main ulcer. Since copper ions kill bacteria and have been shown to stimulate blood vessel development in wounds, this dressing may possibly have beneficial effects on wound healing (and this is what is being evaluated in this study). The choice of standard care wound dressing can be decided by the usual treating clinical staff; this may involve a standard dressing or another dressing designed to kill bacteria such as silver-impregnated dressing.

What are the possible benefits and risks of participating?
The treatment patients receive will not differ from the standard treatment options available, and hence the risks should be very low. This means that if patients do not take part in the study, they will most likely be prescribed one of the wound dressings as part of normal regular care (MedCu copper-impregnated dressing is also available to clinical staff outside this study, though it is locally not listed on the so-called NHS formulary of preferred wound dressing products). Because this study will use wound dressings that are also used in standard care, there may not be an immediate benefit to the patient. However, there is a chance that one of the two dressing treatments that are studied may be more effective. At present we do not know this and this study is designed to find out if this is the case. Patients cannot claim payments, reimbursement of expenses or any other benefits or incentives for taking part in this research. Patients who take part can receive a copy of a summary of the study results, to inform them how the two bandage brands performed in this study. There are no major personal safety risks anticipated regarding patients taking part in this research trial. Dressings themselves may potentially lead to some skin irritation and discomfort; allergy to copper is a very rare occurrence. If patients do decide to take part and the National Health Service (NHS) Trust, surgeon, GP, nurse or the research team learns of important new information that might affect their desire to remain in the study, they will tell the patient as soon as possible. Appropriate precautions are in place to ensure patients’ medical and personal information is kept safe.

Scientific titleProspective, randomised controlled trial assessing MedCu copper dressing for leg ulcer management
Study acronymCUPRA
Study objectivesThis study will aim to determine if treatment of lower limb ulcers with a copper-oxide particle impregnated dressing (called MedCu, or ‘copper dressing’) can aid in accelerated wound healing of lower limb ulcers when compared to standard care dressings.
Ethics approval(s)Approved 11/03/2025, North of Scotland Research Ethics Committee (1) (Summerfield House, 2 Eday Road, Aberdeen, AB15 6RE, UK; +44 (0)1224 558458; gram.nosres@nhs.scot), ref: 25/NS/0020
Health condition(s) or problem(s) studiedLeg ulcer
InterventionWritten informed consent will be taken from the patients. Thereafter, they are randomised to one of two treatment arms (standard care or MedCu copper dressing). Patients will be in the trial for 12 weeks, with outcome measures being taken at weeks 0, 6 and 12. If during this period wound dressing is no longer indicated then it will no longer be applied but outcome measures will still be taken.

At baseline (week 0),4, 8 and 12 weeks, various validated questionnaires will be completed by the participant (focussing on quality of life ) and essential clinical information will be recorded.

As mentioned, relevant baseline clinical information and any changes in the condition of the leg and patient will be recorded too, including any safety outcomes.
Intervention typeOther
Primary outcome measureUlcer wound status (healed or not healed) and dressing (used or not used, and which type) will be recorded at week 0, week 4, week 8 and week 12
Secondary outcome measures1. Ulcer wound size will be measured with the Healthy io App (digital wound size measurement) and validated PUSH score questionnaire at week 0, week 4, week 8 and week 12
2. General quality of life will be measured with validated EQ-5D-5L questionnaire at week 0 and week 12
3. Ulcer-related symptoms will be measured with validated VEINES-Sym questionnaire at week 0, week 4, week 8 and week 12
