Brief summary
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.
Interventions
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.

Intervention model description
This is an open-label extension study. During a clinical care visit, if a patient is eligible and agrees to participate, lesions will be selected by the dermatologist prior to procedure. All lesions selected will be treated with non-thermal atmospheric plasma (NTAP).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of lesions with no response | 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. |
| Number of lesions with partial response | 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. |
| Number of lesions with complete response | Maximum of 12 months | Targeted lesion is no longer grossly visible. |
| Number of treatments to complete lesion resolution | Maximum of 12 months | Comparing number of treatments necessary for complete response. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Adverse events from CAP tolerability questionnaire | 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) |
| Average score of visual analogue scale associated with treatment | 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. |
