Cold Atmospheric Plasma Device Extension Study

March 30, 2026 updated by: Lara Wine Lee, Medical University of South Carolina

Cold Atmospheric Plasma Device for the Treatment of Molluscum Contagiosum and Verruca Vulgaris in Pediatric Patients - Open-Label Extension Study

Patients between 4-21 years of age with at least one wart or molluscum lesion are eligible to participate in this study. The duration of the study is a minimum of 4 weeks with the maximum duration of monthly treatments for one year, depending on lesion clearance. The number of lesions will be chosen by the dermatologist. Patients who opt to participate will receive non-thermal, or cold, atmospheric plasma to treat all lesions selected. Safety profile as well as changes in size, pain and appearance will be measured. Photographs and dermatologist impressions will be used to measure treatment response.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Experimental: Cold Atmospheric Plasma (CAP)
We are proposing an open-label extension study of a floating electrode-dielectric barrier device (FE-DBD), a Cold Atmospheric Plasma (CAP) device for the treatment of Verrucae Vulgaris and Molluscum Contagiosum. While novel to the medical field, and especially to dermatology, there are already a number of publications regarding its use on human skin in adults and children. CAP devices utilize noble gases (such as helium) to deliver plasma state matter to the skin. As its name implies, the generated plasma stream is of near skin temperature and it exists on normal atmospheric pressure. During the generation of the plasma there is no electric contact with the patient. The treatment does not increase skin surface temperature and the used helium gas, the same as used for balloons, being a noble gas does not cause a chemical reaction with the skin. The flow of the gas is slow, thus there is no mechanical effect on the skin.
Device: Floating electrode-dielectric barrier device (FE-DBD) cold atmospheric plasma (CAP)
The treatment device in this study generates cold atmospheric plasma. Cold atmospheric plasma has certain properties of plasma, such as ionized gas molecules. To create plasma, a pulse generator supplying 20 kilovolt pulse of 20-ns pulse width at 200 Hz (FPG10-01NM10, FID GmbH, Burbach, Germany) to a 5-mm diameter quartz-covered copper electrode of 10-cm length and 1 - 13mm quartz thickness. These nanosecond pulse parameters were chosen to provide sufficient treatment dose at the high level of plasma uniformity required to avoid any tissue damage. We will treat the lesions for approximately 1 to 2 minutes each, moving the electrode gently over the treatment area.

  • Non-thermal atmospheric pressure plasma (NTAP)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of lesions with no response
Time Frame: Maximum of 12 months
Absence of change in appearance of targeted lesion. Molluscum is defined as the visualization of a central umbilication with polylobular, white to yellow, amorphous structures. A peripheral crown of radiating or punctiform vessels may also be present. Warts are defined as grouped papillae, with dotted or loop vessels, and/or hemorrhagic points and lines often surrounded by a whitish halo.
Maximum of 12 months
Number of lesions with partial response
Time Frame: Maximum of 12 months
There is change in the size, dyspigmentation, or discomfort of the targeted lesion as compared to its appearance and symptoms at the initial visit, but the lesion remains grossly visible. Molluscum is defined as the visualization of a central umbilication with polylobular, white to yellow, amorphous structures. A peripheral crown of radiating or punctiform vessels may also be present. Warts are defined as grouped papillae, with dotted or loop vessels, and/or hemorrhagic points and lines often surrounded by a whitish halo. Changes in the characteristics of the targeted lesions will be evaluated by a dermatologist and documented via photographs at follow-up visits at 4, 8, and 12 weeks, with the final outcome measured at the 12-week visit.
Maximum of 12 months
Number of lesions with complete response
Time Frame: Maximum of 12 months
Targeted lesion is no longer grossly visible.
Maximum of 12 months
Number of treatments to complete lesion resolution
Time Frame: Maximum of 12 months
Comparing number of treatments necessary for complete response.
Maximum of 12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Adverse events from CAP tolerability questionnaire
Time Frame: Maximum of 12 months
This questionnaire measures tolerability of cold atmospheric plasma treatment. Assessment of dryness, peeling, scaling, erythema, edema, stinging, burning sensation, itching, scarring and dyspigmentation will each be assessed individually by means of a standardized grading scale (0 = absent; 1 = mild; 2 = moderate; 3 = severe)
Maximum of 12 months
Average score of visual analogue scale associated with treatment
Time Frame: Maximum of 12 months
The visual analogue scale (VAS) is a validated subjective measurement of pain experienced by the patient. It consists of visual-numeric scale, numbered from 0-10. (0) indicate absence of pain or "no pain at all", while (10) indicates severe pain or "worst imaginable pain". This is supplemented by six faces with different expressions, ranging from happy to extremely upset. Each facial expression is assigned a numerical scale from 0 to 10.
Maximum of 12 months
