Brief summary:
This study is going to test a cold atmospheric plasma device (CAP), in particular a floating electrode-dielectric barrier device (FE-DBD), to treat warts and molluscum. The treatment device in this study generates cold atmospheric plasma (gaseous ionized molecules) to rid the virus from the body. Based on the successes of previous dermatologic studies, FE-DBD is being tested for this study to treat warts and molluscum. Patients will be enrolled to test the efficacy and safety of this device. The duration of the study is 4-12 weeks depending on treatment clearance. The number of lesions will be chosen by the dermatologist. Patients will receive standard of care therapy and/or NTAP depending on the number of lesions.

Detailed description:

Arms: arm 1: We are proposing a clinical trial 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. arm 2: Current standard of care (SOC) for treating Verruca Vulgaris in Children is cryotherapy. Patients randomized to this arm of the study will receive SOC treatment for their identified condition. arm 3: SOC for treatment of Molluscum Contagiosum is cantharidin. Patients randomized to this arm of the study will receive SOC treatment for their identified condition.
Interventions: intervention 1: Floating electrode-dielectric barrier device (FE-DBD) cold atmospheric plasma (CAP) intervention 2: Cryotherapy intervention 3: Canthardin Collodion
Intervention descriptions: intervention 1: 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 2: Cryotherapy refers to the application of liquid nitrogen using a cryospray device in order to freeze a lesion of interest. Treatment is repeated every few weeks until the lesion of interest has disappeared. It is considered SOC for the treatment of warts. intervention 3: Chemical compound that acts as a vesicant to form a blister around treatment area. The blister lifts the lesion of interest away from the skin, causing it to slough off in a few days. It is used as SOC for the treatment of Molluscum Contagiosum.

Objectives / Specific Aims 
• 
Objective: Study the safety and efficacy of uniform nonequilibrium, nonthermal 
atmospheric pressure plasma (NTAP)/cold atmospheric plasma device (CAP) in the 
treatment of molluscum contagiosum and vercurra (warts) in children 4-21 years.   
• 
Aim:  
§ Measure the changes in size, pain and appearance of verrucae and 
molluscum after 4, 8 and 12 weeks.  
§ Evaluate the safety profile and patient tolerability of the treatment by 
analyzing potential side effects and pain levels, or lack thereof, with each 
treatment.    
• Hypothesis: NTAP will be an equally efficient and painless alternative to cryotherapy 
for the treatment of molluscum and warts.  
2.0 
Background 
 
Molluscum contagiousum (MC) and warts are common viral disease in children. They result from an 
infection with a double stranded DNA virus (1). Diagnosis is clinical, presenting as smooth, round 
papules with central umbilication in MC and irregularly surfaced domed lesions in warts. Although 
benign and generally self-limited, these conditions are contagious and can lead to complications such as 
inflammation, pruritus, dermatitis, scars and superinfections (2). There is little consensus concerning the 
management of these conditions. Treatment options include mechanical destruction with cryosurgery or 
heat, topical irritants, topical vesicants and topical acids (3). These strategies are often irritating and/or 
painful making application to children very difficult, particularly in cases where many have to be treated 
at once. 
 
Physical plasma has been considered the fourth state of matter. Biomedical application at lower-
temperature plasma have been regarded as one of the most significant opportunities in plasma science. 
Nonthermal, cold and non-equilibrium plasma synonymously mean plasma that is not in thermodynamic 
equilibrium because the electron temperature is significantly warmer than heavy species. When the 
electrons are thermalized their velocity distribution is very different from the ion velocity distribution 
leading to modification in DNA, proteins and cell membranes. Most NTAP plasmas are generated in 
helium or argon mixed with a number of reactive gases (7). This creates a low ion energy environment 
with a rapid reaction response in which UV light and reactive oxygen and nitrogen species induce a 
focused, transient antiviral or antibacterial milieu (18). NTAP offers direct delivery to the sample surface 
without the complications of a vacuum chamber to physically burn the tissue and trigger a complex 
sequence of biological responses in tissue and cells (4). Plasma does not cause lasting damage to the skin 
or skin functions, indicating a very favorable safety profile for its application in treating cutaneous 
pathologies (20).  
 
 
Plasma affects cells in a dosage-dependent manner by disrupting cell-cell adhesion and cell detachment 
from substrates (12). The short-term exposure temporary causes cell membrane permeabilization, 
inhibiting cell migration. Longer exposure times and higher intensity plasma induces apoptosis or 
necrosis by reactive oxygen and nitrogen species. Several pilot studies have confirmed that NTAP induces 
multiple modes of cell death in human melanoma and hepatocellular carcinoma. The plasma damaged 
cells begin to repair the damage with releasing growth factors (ex: fibroblast growth factor 2) (12).

In the biomedical field, NTAP has a broad range of applications including disinfection of living tissues, 
blood coagulation, induction of apoptosis in malignant tissues, a localized modulation of cell adhesion 
and proliferation and tissue modification of interest in electrosurgery (5-7,9,10). The first small scale 
clinical studies have shown plasma treatments were well tolerated, painless and, most importantly, 
without side effects (20-26). In a risk assessment of UV radiation and temperature, it was shown that UV 
radiation of the plasma is an order of magnitude lower than the minimal erythema dose necessary to 
produce sunburn on the skin in vivo. Additionally, thermal damage of the tissue by the plasma can be 
excluded since the electrons and ions are not in thermal equilibrium, thereby resulting in “cold,” rather 
than “hot” plasma, which is actually room temperature upon tactile examination. 27).  
Multiple modes of NTAP, also known as  cold atmospheric plasma (CAP), have been employed in 
dermatologic clinical studies such as wound healing, onychomycosis, actinic keratosis and viral warts 
(28). Friedman’s case series on warts proved it safety and efficacy in children, reporting no adverse events 
(blistering, scarring, significant pigmentary alteration or persistent nail changes) or pain reported in 
treatment (29).  A proof-of-concept study on warts in children demonstrated efficacy and exceptional 
tolerability when treated with plasma as a result of its intracellular calcium influx and viral replication 
inhibiting effects. In actinic keratosis they had a 70% improvement rate with no discomfort during or after 
treatment. Onychomycosis had a 50% clinical and 15% mycological cure rate in 13 patients without any 
side effects. And wound healing of chronic ulcers had decreased bacterial as expected from well-
documented inhibitory effects on bacteria and also superior wound healing rates compared to wound care 
alone.  Moreover, it has been shown to be safe and successful in proof-of concept studies exploring its 
application in the treatment of Verruca vulgaris. Its efficacy in molluscum has not yet been tested.  
Given NTAP’s outstanding safety profile and painless application (5), its prior proof of concept success in 
treating common verrucae, and the similarity between verrucae and molluscum, we propose to use NTAP 
to treat these conditions and expand upon the existing research literature. 
If the NTAP device is shown to be a successful, efficacious and painless treatment option for children and 
adolescents with verrucae and molluscum, this would be a revolutionary and environmentally friendly 
approach to two of the most common viral infections and chief complaints found during dermatology 
visits in this age group. The non-toxic, chemical free, waste free, multi-year device results in a significant 
reduction of effluents, which is beneficial from an economic but also an environmental viewpoint (30). 
 
3.0 
Intervention to be studied (if applicable) 
 
We will utilize a floating electrode-dielectric barrier device (FE-DBD) Cold atmospheric 
plasma (CAP) device on molluscum and warts in children and adolescents 4-21 years 
(Figure 1). Children and adolescents are targeted because they are the population most 
affected by painful standard of care therapy. The study will continue until at least 68 warts 
and 68 molluscum are treated. Each patient will not have more lesions treated than SOC 
recommendations.  Half the lesions will be treated with plasma and the other half with 
standard of care being cryotherapy for warts and cantharidin for molluscum. A single 
patient must have minimum of 1 clinically diagnosed lesion treated and maximum of 20 
treated. Lesions with a clinical impression of warts or molluscum will be selected. 
Selection of treatment type (control vs NTAP) will be randomly selected. Lesions

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-kV 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-
mm quartz thickness (5). 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 
treated the lesions for approximately 1 to 2 minutes each, moving the electrode gently over the 
treatment area.  
 
After the study treatments are completed, we will analyze the data to see if the treatment was safe 
and effective. 
Non-significant risk device statement (6-19) (Figure 1) 
o We are proposing a clinical trial floating electrode-dielectric barrier device (FE-DBD) a Cold 
Atmospheric Plasma (CAP) device.  
o While novel to the medical field and especially to dermatology, there are already a number of

gas - the same as used for balloons - being a noble gas does not develop a chemical reaction 
with the skin. The flow of the gas is slow, thus there is no mechanical effect on the skin.  
o Previous clinical studies used these devices on skin surfaces that were denude, eroded or 
ulcerated and even without intact skin barrier function there were no reported adverse effects. 
In fact, one study specifically examined the tolerability of plasma treatments of various 
equipment and found that the plasma was well tolerated and had no adverse effects on the skin 
surface. 
o Based on the principles of the treatment as well as the below referenced prior studies we 
believe that this non-invasive method of treatment will be performed using equipment that 
certainly qualifies for a minimal-risk device that will not harm normal skin.

Fig. 1. Floating-electrode DBD plasma. Top panel: pulse generator and hand-held electrode. Bottom panel: 
Plasma is being generated using the electrode tip. The electrode connected to the pulse generator must be kept 
near the treated surface. Either the tip or the side of the electrode can be used, but plasma will only form where 
the gap between the electrode and the target surface does not exceed 1 mm. This device pictured will be used in 
our trial.   
 
Clinical safety of plasma (28): 
Standards are issued by the national regulatory authorities like UV radiation, ozone, nitrogen oxide 
and electrical current. Assuring compliance to maintained through measuring values for every CAP 
device and exposure limits. The presence of reactive species raises a concern for the mutagenicity 
of CAP; however, all devices were found safe within the operating parameters studied. To ensure 
safety of each CAP device, everyone must be tested on standards developed by the International 
Organization on Plasma Medical Device and Standardization (IOPMS) with Dr. Alexander Fridman 
representing the US. IOPMS is considering device safety under the major aspects:

Dermalite dermatoscopes will be used to assess diagnosis and resolution. They are approved 
by the FDA for the study indication. Dermoscopy, also known as dermatoscopy, 
epiluminescence microscopy, incident light microscopy, or skin surface microscopy, is 
performed using a handheld instrument called a dermatoscope or dermoscope, which has a 
transilluminating light source and standard magnifying optics (10×). The dermatoscope 
facilitates visualization of subsurface skin structures located within the epidermis, 
dermoepidermal junction, and papillary dermis, which are otherwise invisible to the unaided 
eye. Colors and structures visible with dermoscopy are required for generating a correct 
diagnosis.

Study Endpoints (if applicable) 
• Clinical assessment response after 4, 8 or 12 weeks. This will be assessed by a blinded 
study team member comparing clinical photographs and dermascopic images.  
• Clinical photographs measured by no response, partial resolution, complete 
resolution.  
• Dermoscopy images: no response, partial resolution, complete resolution using the 
guidelines below that indicate the presence of wart or mollusum.  
§  Molluscum: Visualization of a central umbilication with polylobular, white to 
yellow, amorphous structures is typical. A peripheral crown of radiating or 
punctiform vessels is also present. 
§ Wart: grouped papillae, with dotted or loop vessels, and/or hemorrhagic points and 
lines often surrounded by a whitish halo 
• Visual analogue scale for experimental treatment and control treatment  
• 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.   
• Evaluation of tolerability included assessment of dry ness, peeling, scaling, erythema, edema, 
stinging, burning sensation, itching, scaring and dyspigmentation. They will be assessed by 
means of a standardized grading scale (0 = absent; 1 = mild; 2 = moderate; 3 = severe)

Recruitment Methods 
Recruitment will occur during standard of care visits to the Dermatology and Pediatric 
Dermatology Clinics, virtual visits, and chart review of eligible patients.  
For standard of care visits, someone directly involved in the participants patient care will 
assess the patient’s eligibility and inform eligible patients and/or their legal guardian about 
this study. If they are interested, the study team members will approach the patients or their 
legal guardian without coercion and with the emphasis on the voluntary aspect of being on 
this study. Subjects will also be told in a caring manner that no matter what their decision is, 
it will not affect how their doctor cares for them as a patient or their care in general.   
Potential subjects who contact the study team members directly will also be considered for 
participation in the study. In this event, these potential subjects must have heard about the 
study through indirect information sources (clinicaltrials.gov or other means by which the 
study team members did not directly advertise the study for purposes of recruitment). If they 


Version 3; Version Date: 4/14/2022 
 
Page 8 of 13 
 
are interested, the study team members will respond to them via email, and subsequently 
approach the patients virtually without coercion and with the emphasis on the voluntary 
aspect of being on this study. Subjects will also be told in a caring manner that no matter 
what their decision is, it will not affect how their doctor cares for them as a patient or their 
care in general.   
9.0 
Consent Process 
 
Potential subjects and/or their legal guardians will be approached by researchers at MUSC Dermatology 
and Pediatric Dermatology clinics. Members of the team will approach their own patients to ask for 
participation. Pertinent project information, risks and time commitment will be relayed to subjects. If 
subjects show interest in participating, they will be given an assent form to either sign or bring home for 
consideration.  
Minimally, an adult parent with legal custody of a child or an adult awarded legal custody of a child must 
give informed consent for a child to be enrolled in research. A child 12 years of age or older must give 
documented "assent" to be enrolled in research. The assent will be documented on the informed consent 
document. An "emancipated minor" must provide documentation of his/her financial independence such 
as a rental lease, marriage certificate or court document in his/her name proving emancipation before 
consenting as an adult to participate in research. If child reaches 18, while enrolled on the study they will 
be reconsented without parents. All patients 18 years and older will be consented as adults.  
 The consent process will occur in a private room; the research team will explain to the participant and/or 
their legal guardian a language they can understand what it means to take part and what they can expect. 
Research team members will be obtaining assent when applicable.  The research team will use language 
and terminology that will be understood by participant. A device demonstration will be showed to the 
child and their parents. The child and parents will be encouraged to ask questions at the end and sign their 
understanding. No waiting period will be necessary between informing the subjects and obtaining the 
consent however, subjects will be allowed to take home the unsigned consent form for review prior to 
signing it if needed and reschedule another visit for treatment as soon as possible.

Study Design / Methods 
 
• A chart review of patient the patient’s medical record will be completed and the following 
information will be collected for research purposes: DOB, demographics, contact information 
and diagnosis.  
• Skin irritants, emollients, topical medications and other topical products cannot be applied to 
the study area 4 weeks prior to the start of the study and throughout the duration of the study. 
Details of what can and cannot be used can be discussed any time.  
• During a clinical care visit, if a patient is eligible and agrees to participate, lesions will be 
selected by the dermatologist prior to procedure. The lesions will be marked randomly for a 
certain treatment regimen and photographs will be taken before each treatment and after 
completion of the study. Identifiers will be covered to protect identity. All images will be 
saved on a MUSC network secure box drive using a subject study number.  
• The number of lesions treated will not exceed SOC recommendations. They will be 
determined by provider assessment and anatomical location.  
• Participants with one lesion will receive either NTAP or standard of care (SOC). SOC is 


Version 3; Version Date: 4/14/2022 
 
Page 9 of 13 
 
cryotherapy for warts and cantharidin for molluscum. Participants with greater than 2 lesions 
will receive equal treatment of NTAP and SOC. The number of lesions treated will be based 
off the providers assessment and anatomical location. Treatment of a single lesion or an odd 
number of multiple lesions will be based off a randomized list.  
• All SOC lesions will be treated first to reduce the number of patients not wanting return to the 
more painful modality.  
• All people in the room will be provided eye shields that must be worn during treatment. The 
patient will be placed in a comfortable position before the lesion is cleaned with alcohol.  
• Each lesion will be treated for 1-2 minutes. Total treatment duration will be no longer than 20 
minutes.  
• The interval between treatment groups will about 1 minute. 
• There will be a follow-up phone call a week after treatment to check on resolution and report 
any adverse events. If an adverse event is reported the study team members will access if the 
patient needs to be seen by a provider that day. 
• Patient will return to the office for a 4-week standard of care follow-up. Study cessation or 
additional treatment will be determined by the provider assessment of lesion clearance. If 
lesion persist another treatment will occur.  No greater than 3 treatments will be performed.  
• This study will be single blinded, meaning the study team member accessing the results will 
not know which lesions were treated with what therapy. Assessment of clearance will be based 
off of clinical examination and images. The team will record any additional  clinical feature 
that may arise during the analyses. 
 
11. Data Management  
• Continuous data will be summarized using descriptive statistics (number of values, 
means, standard deviation, median, minimum and maximum). Categorical data will 
be summarized using frequency tables (frequencies and percent). 
• Chi-square analysis comparing the proportions of successes (equal chance 
outcomes).  
• Coded dermoscopic and clinical photographs may be obtained for further analyses 
after each visit. Files with patient images will be stored in a secure departmental drive 
that will only be accessible to study team members by their unique MUSC ID and 
password. 
• All subject medical record information and data collection will be coded and stored 
on an MUSC Box drive only accessible to study team members and will be protected 
by two-factor authentication. The linking document between ID and PHI will be 
maintained separately from the study data in a separate encrypted folder.  
14.0 
Withdrawal of Subjects (if applicable) 
•  Patient may withdraw at any time.  Subjects may verbally notify investigators if they wish to 
voluntarily withdrawal from the study immediately. All data collected until this point will be 
retained for study purposes.

Risks to Subjects 
 


Version 3; Version Date: 4/14/2022 
 
Page 10 of 13 
 
Risk for NTAP: To date, there are no known side effects or risks associated with the use of cold 
atmospheric or studies producing discomfort or pain ( 20-26, 29).  However, because this is an 
experimental device, side effects like blistering, scarring, significant pigmentary alteration, and/or  
persistent nail change could occur and will be monitored at each visit, as well as pain assessment 
at every treatment session by validate pain scale (VAS).  
 
The treatment received may prove to be less effective or to have more side effects than the other 
study treatment(s) or other available treatments. 
  
This is a new device and even though no side effects of this treatment are reported in literature to  
date (27), the IRB will be notified via amendment, as well as participants via phone call if one 
arises.  
There is a risk for possible breach of confidentiality. However, all measures to keep 
information protected will be taken. Photographs will be stored in the coded study-specific 
medical record for further analysis of lesion features. Only study team members will be able 
to access.  
A cumulative data assessment will be conducted every other month throughout the study’s 
duration by study team members. A report that includes any available efficacy data, as well 
as a record of anticipated adverse events, can be compiled and submitted to the IRB at that 
time. Any event meeting the criteria of an unanticipated problem involving risks to 
subjects or others will be immediately reported to the MUSC IRB, as required by HRPP 
4.7- Unanticipated Problems and Adverse Events Policy and Procedures.  
The plan for subject safety and minimizing risks of the research is assessing AE during, 
immediately following treatment and a few days after. Participants are encouraged to reach 
out to the study team if they think they are experiencing any adverse events. Other 
expected adverse effects deemed intolerable by the patient will prompt reduction in the 
patient’s frequency, duration and treatment if indicated. Any condition necessitating 
cessation of the study drug will be followed to resolution.  
16.0 
Potential Benefits to Subjects or Others 
 
Improvement may be seen in Molluscum Contagiosum and Verruca Vulgaris from participating in 
the study. However, there is no guarantee. Participation may help other patients in the future by 
increasing awareness and making it more readily available.
