Study summary

The goal of this clinical trial is to evaluate the effectiveness of cold atmospheric plasma treatment in promoting the healing of chronic wounds in adult participants suffering from chronic wounds. The main questions is the following: Does the application of cold atmospheric plasma accelerate wound healing compared to standard wound care alone?

Researchers will compare standard of care plus plasma treatment with standard of care alone to see if the plasma-treated group shows faster wound healing.

Participants will:

  • Receive either standard wound care alone or standard wound care combined with cold atmospheric plasma treatment, depending on randomization.
  • Attend scheduled hospital visits for wound care, treatment administration, and clinical assessments, including wound photography and quality of life questionnaires.
  • Be followed up at home by nurses for wound care, treatment administration and clinical assessment too.
  • Complete a wound-related quality of life questionnaire at baseline, at week 6, and at the end of the study.
Read the detailed description

This is a multicenter, randomized, controlled clinical trial evaluating the efficacy and safety of cold atmospheric plasma (CAP) therapy using the Plasana One® device in the treatment of chronic wounds. The study aims to compare the outcomes of standard of care alone versus standard of care combined with plasma treatment.

60 eligible participants presenting with chronic wounds (such as venous leg ulcers or diabetic foot ulcers) will be randomized into two groups:

  • One group will receive standard wound care as per clinical practice.
  • The other group will receive standard wound care along with cold plasma therapy administered using the Plasana One® device.

    6 participants suffering from pressure ulcers will also be included for an ancillary study.

The study includes both hospital-based and home-based components. Key study procedures include wound assessment through photography, clinical data collection using an electronic case report form (eCRF), and evaluation of patient-reported outcomes such as quality of life (Wound-QoL questionnaire).

Treatments and follow-up visits will be conducted by hospital investigators and home healthcare professionals, depending on the participant's care pathway. Plasma treatment will be delivered by trained nurses during home visits, with gas supplies and device management coordinated by a home care service provider (PSAD).

The primary objective is to evaluate the efficacy of the cold plasma device Plasana One® in the local management of chronic wounds in participants suffering from diabetic foot ulcers and venous leg ulcers, at Week 6.

Secondary objectives include wound healing progression, quality of life, safety of plasma application, and user satisfaction over a 20-week period.

The objective of the ancillary study will be to describe the healing process in pressure ulcers.

Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Jun 2025; primary completion for Jan 2026, 7 months later.

Of 66 industry-sponsored interventional studies with no phase under Varicose Ulcer, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 13 and three quarters within 37. This study's planned 7 months is below that.

Counting every sponsor, half of 133 studies reached it within 28 months; a quarter within 13 and three quarters within 48.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 9, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
