2 INTRODUCTION
2.1 STUDY RATIONALE
The use of electrocautery technology is safe and effective for the treatment of various dermatologic conditions including acne scars, actinic keratoses, superficial skin lesions, small angiomas and molluscum.1,2 Additionally, it is safe and effective method for hemostasis in cutaneous surgeries.1,2 Its application is well established in the current literature and is a commonly used technique in various minor surgical procedures in dermatology, ophthalmology, otolaryngology, plastic surgery and urology.3 The objective of this clinical study is to evaluate the safety and histological effects of the Nu-Vissa, a handheld battery-operated plasma generating device, on healthy human tissue.
The use of the Nu-VissaTM has been determined to present a non-significant risk in accordance with 21 CFR 812.3 for the intended use in this study, because the device is not: • Intended as an implant.
- purported or represented to be for use in supporting or sustaining human life; • for use of substantial importance in diagnosing, curing, mitigating, or treating disease, or
10 of 38
Effects of Hand Held Plasma Device on Healthy Tissue Version 1.0 Protocol # NEO19-NV-01 05 November 2019
otherwise preventing impairment of human health; or
- Otherwise presenting a potential for serious risk to the health, safety, or welfare of a subject.
Furthermore, use of electrocautery has been reported without significant complications or incident in various clinical studies.1,2,
2.2 BACKGROUND
Electrocautery refers to a process in which heat is generated by way of an alternating or direct electrical current that is passed through a resistant metal wire electrode. The heated electrode is then applied to the skin to achieve desirable amounts of tissue destruction.4 Unlike electrosurgery, the electrical current does not pass through the patient. This is particularly important in patients who are not ideal candidates for electrosurgery due to the presence of implanted devices and the risk for external electromagnetic interference.5,6 Although stark differences are evident between electrocautery and electrosurgery, the two share several common indications for use including, small angiomas, seborrheic keratoses, molloscum, wart removal, skin tags and chronic epistaxis.1,2 Electrocautery is also commonly used in minor surgical procedures in which hemostasis is required and has been beneficial in procedures such as functional occlusion related to dry eye syndrome.1,7,8,9
Several studies have been done that examine the safety, tolerability and efficacy of electrocautery for various conditions and is well supported in the current literature.10.11 The current study aims to evaluate the histological effects of a single plasma generated treatment to human tissue. A more in depth understanding of the wound healing and injury process taking place on a cellular level after treatment will assist in broadening the safety profile of the device and provide possible evidence for its use in other indications in future studies.
2.3 RISK/BENEFIT ASSESSMENT
2.3.1 KNOWN POTENTIAL RISKS
Electrofulguration Risks
Anticipated adverse events associated with hand held plasma generating devices include mild and transient discomfort, skin irritation, localized edema and minimal bleeding. In addition, other complications include injury to surrounding structures, blood vessels or nerves, scarring, thermal injury, infection and interference with pacemakers or implantable cardioversion defibrillators.
11 of 38
Effects of Hand Held Plasma Device on Healthy Tissue Version 1.0 Protocol # NEO19-NV-01 05 November 2019
Punch Biopsy Risks
Possible risks associated with biopsies include pain, edema, erythema, bleeding, scarring, ecchymosis and infection.
Surgical Marker Risks
A surgical marker may be used to outline the treatment area. There are minimal risks associated with the use of a surgical marker, but it may produce erythema or contact dermatitis. It is possible that markings may remain visible on the skin for 1-3 days, but alcohol may be used to remove markings.
Anesthetic Risks (Lidocaine with or without 1% epinephrine)
Potential risks associated with lidocaine include mild bruising, rash, erythema, pruritus, edema, nerve damage and/or temporary loss of sensation or muscle function at the injection site. Though rare, a serious complication to lidocaine is allergic-type reactions which include anaphylaxis.
Potential risks will be mitigated by conducting this protocol with an investigator who will be trained by the sponsor on the use of the device. Subjects will undergo thorough screening to ensure the study criteria is met prior to enrollment. The study site staff will confirm subjects continue to meet the enrollment criteria throughout the duration of the study.
- 2.3.2 KNOWN POTENTIAL BENEFITS
If the subject agrees to participate in this study, he/she will be contributing to the understanding of the
thermal effects and safety of this investigational device on healthy human tissue. As the study is evaluating the effects of the device on healthy human tissue, participants may not experience any direct benefits from treatment. However, a better understanding of the safety and effects of the device on healthy human tissue may lead to optimization of treatments for future procedures.

6 STUDY INTERVENTION
6.1 DEVICE DESCRIPTION AND SPECIFICATIONS
The Nu-VissaTM electrocautery device used in this study is considered investigational because the handpiece has not yet been cleared for use by the U.S. Food and Drug Administration (FDA).
The investigational device (Nu-VissaTM) is a high voltage, low amperage, hand-held plasma generating pen. The portable device uses direct current (DC) to generate a sinusoidal signal that is applied to an electrode shaped as a needle located at the end of the handpiece. Concentrated energy is transferred by way of high voltage, low amperage electrons that create a spark (ionization) when approximately 1mm from the tissue resulting in superficial fulguration. After treatment the tissue cools down by evaporation of lesional fluids without the overheating of surrounding tissues. The electrical signal and sinusoidal signal have a maximum power value of 2 Watts. The signal has an operating voltage of 750VAC and a frequency of 50-60Hz.
The Nu-VissaTM needle is designed for one time use only and should be disposed of after each treatment.

8.3 SCHEDULE
8.3.1 SCREENING (VISIT 1)
The Principal Investigator or his/her designee will assess the subject eligibility for participation in the clinical study using the inclusion/exclusion criteria (Sections 5.1; 5.2). Subjects meeting the study criteria for enrollment will be asked to sign an informed consent document. The Principal Investigator or his/her designee will obtain informed consent from the subject. All subjects must clearly indicate his/her understanding of the requirements and possible risks involved with study participation. Once subjects sign the informed consent document, they will be assigned a unique identifying number that will be composed of a two-digit site number and a three-digit subject number in sequence. This unique identifier will be used throughout the entire study and will be entered in the subject’s case report form (CRF) and for each biopsy visit.
19 of 38
Effects of Hand Held Plasma Device on Healthy Tissue Version 1.0 Protocol # NEO19-NV-01 05 November 2019
During the screening visit, the Principal Investigator or his/her designee will review the subjects medical/surgical history, demographic information, concomitant medication and examine the treatment area.
Women of child-bearing potential will be asked the date of their last menstrual cycle and required to provide a urine sample for a urine pregnancy test. A negative result is required within 24 hours of treatment for participation in study. The investigator will inquire about contraceptive use to confirm they meet the inclusion criteria.
Treatment and screening may take place on the same day if negative pregnancy test is confirmed and the subject meets all criteria for enrollment.
8.3.2 PRETREATMENT (VISIT 1)
Pre-treatment
The practitioner will identify an area of approximately 3 inches x 3 inches of healthy tissue on your shoulder or back that will be treated with the Nu-Vissa device. The area will be cleansed and a local anesthetic, such as lidocaine, may be injected or applied topically to the treatment area prior to biopsy.
A surgical marker may be used to outline the treatment area.
The following pre-treatment instructions will be reviewed:
- Shave any dense hair in the treatment area prior to procedure
- Avoid any constrictive clothing on the day of treatment
- Ensure treatment area is free of any open wounds or active infection
Standard pre-treatment instructions will be reviewed, and the subject will be instructed to adhere to the following:
- Do not receive other treatments within the study area for the duration of the study. ● Do not apply any products, including lotion and sunblock, to the general area for at least 12 hours prior to each study visit.
- The treatment area must remain free of any open lesions or active infections. ● General recommendations such as proper hydration and avoidance of alcohol several days prior to treatment and biopsies is encouraged.
8.3.3 TREATMENT (VISIT 1)
The investigator will confirm that the subject continues to meet the inclusion criteria and none of the exclusion criteria if treatment is scheduled on a different date than screening visit.
20 of 38
Effects of Hand Held Plasma Device on Healthy Tissue Version 1.0 Protocol # NEO19-NV-01 05 November 2019
The treatment area will be cleansed with a non-alcohol-based cleanser, such as chlorhexidine.
Lidocaine 1% either with or without epinephrine (at investigator discretion) will be injected into the treatment area per clinic protocol.
A needle will be secured into the receptacle of the NuVissa device and tightened. The device will be turned on and put into the “continuous mode” setting. The device will be held approximately 1mm away from skin during treatment. The treatment will last approximately 1 minute. The investigator will monitor for adverse events throughout procedure. Once the treatment is complete, device will be turned off and needle will be disposed of in an appropriate sharp’s container.
Biopsy will take place within 5 minutes post treatment.
A 2-3mm punch biopsy will be obtained adjacent to the treatment area as the control specimen. Additional lidocaine may be injected into this area if needed. Ensure area is properly anesthetized and patient reports numbness for procedure.
Punch biopsy procedure:
- This is a sterile procedure. Follow clinic protocol and ensure sterile field and sterile gloves are worn.
- Using a sterile 3mm skin punch, the investigator will apply pressure and twist in a “drilling” motion until the blade of the skin punch has pierced the epidermis of the skin. The blade should be about ½ exposed. It is normal for the patient to experience a pressure and twisting sensation, but they should not experience pain.
- As the punch enters the subcutaneous fat, resistance will lessen. At this point, the punch should be removed.
- Great care should be taken not to damage the epidermis by crushing it with forceps or by cutting it with a scalpel unnecessarily. Forceps can be used to grab the dermis of the cored skin, pulling up the core to reveal excess dermis and subdermal fat, and with a scalpel in one or two cutting motions the core skin can be cut free. Alternatively, curved iris scissors may be used without using forceps.
- If the tissue core does not pop up, it may be elevated by use of a hypodermic needle or fine-tooth forceps. A portion of the subcutaneous fat should be included in the specimen.
- The specimen should be placed in the specimen container. Ensure proper labeling. Once labeled, specimen will be sent to the dermatopathology lab for analysis. 7. Hemostasis can be achieved by applying pressure with a 2×2 gauze pad.
If sutures are required, investigator will suture incision per clinic protocol.
Any adverse events will be recorded in subject’s CRF.
8.3.4 POST-TREATMENT INSTRUCTIONS
21 of 38
Effects of Hand Held Plasma Device on Healthy Tissue Version 1.0 Protocol # NEO19-NV-01 05 November 2019
Standard post-treatment instructions will be reviewed, and the subject will be instructed to adhere to the following:
- The local anesthetic used for the biopsy will usually last for 1 to 2 hours after the procedure. After it wears off, you may have some mild, localized tenderness and slight redness at the biopsy site over the next day or two. Acetaminophen (Tylenol) or Ibuprofen can be used for discomfort.
- If you experience symptoms of infection including fever, increased pain or redness, swelling, pus or excessive drainage contact the study site immediately.
- There should be no excessive bleeding after the procedure. If the incision site does bleed, apply firm pressure for 10-20 minutes. If the site continues to bleed despite pressure call the study site immediately.
- Keep the wound dry. Avoid hot tubs, swimming or any other activity where the incision may be soaked. Avoid soaking the incision site for at least 14 days.
- When showering takes special care not to rub or pick at the incision. Trauma to the area increases the risk for scarring.
- After showering, gently pat the area dry. Petroleum jelly may be applied to the incision area twice daily to prevent formation of a hard scab or crusting. This will also minimize scarring.
- The dry dressing can be removed 24 hours after the procedure. You may wish to apply an adhesive bandage over the wound to prevent irritation or rubbing of the treatment area.
- The biopsy site may appear slightly darker than the rest of your skin. You can expect this discoloration to gradually fade over the next few months to a year.
- You may take a shower 1 day after the procedure. Take care to not scrub the treated and lightly pat dry.
- Do not over bend or stretch the incision site.
- If suture removal is required, you will be asked to return to the study site 7-10 days after the biopsy for removal per the study protocol. If the provider used steri-strips, they will fall off on their own but the incision must be kept dry for 7-10 days, as they separate easily when wet.
- Once the sutures are removed, continue to put petroleum jelly on the incision area to keep the wound from crusting.
8.3.5 BIOPSY (VISITS 2, 3, 4)
Subjects will return for subsequent biopsies at 24 hours post-treatment, 7 days post-treatment and 14 days post-treatment.
Adverse events and concomitant medications will be recorded at the start of each visit. If a side effect or adverse event is tracked, the site will continue to call the subject until the event resolves. If deemed necessary by the investigator, the subject may attend an unscheduled visit for side effect assessment.
22 of 38
Effects of Hand Held Plasma Device on Healthy Tissue Version 1.0 Protocol # NEO19-NV-01 05 November 2019
If suture removal is required, it will be done 7 days (+/- 3 days) post each biopsy. This timeline coincides with the additional biopsy visits.
Lidocaine 1% without epinephrine will be injected per clinical protocol to the defined treatment area.
One (1) 2-3mm punch biopsy specimen will be obtained inside the defined treatment area at visits 2, 3 and 4.
8.3.6 FOLLOW-UP VISIT OR PHONE CALL
At 7 days post-biopsy visit 4 the subject may be asked to return to the clinic for evaluation of the biopsy site and for suture removal (if applicable).
Alternatively, a follow-up phone call can be done in place of the follow up visit if sutures were not required. Principal investigator or his/her designee will contact subject to inquire about adverse events. Adverse events will be recorded in subject’s CRF. If a side effect is tracked, the site will continue to call the subject until the event resolves. If deemed necessary by the investigator, the subject may attend an unscheduled visit for side effect assessment.
8.3.7 HISTOLOGY
Specimen procurement kits will be provided by sponsor and shipped to study site prior to study initiation.
All tissue samples obtained will be labeled with the subjects’ unique identifier, date and time of harvest.
Sample should be placed in appropriate test tube in procurement kit and preserved in 10% formalin. Place specimen in supplied mailer and send to the specified laboratory for analysis. Investigator is to ensure that all required information is completed on specimen label and request form.
Collected biopsy samples will be mailed to specified laboratory for tissue processing, embedding (paraffin blocks) microtomy, slide preparation. Hematoxylin-eosin stain slides will be prepared from each paraffin block per the laboratory’s protocol. Using routine light microscopy, the slides were histologically evaluated.
Pathologist(s) will be blinded to applied treatment characteristics until the completion of the study.
Tissue response may be assessed using the common histological characteristics of wound healing (amount of granulation tissue, inflammatory infiltrate, collagen fiber orientation, pattern
23 of 38
Effects of Hand Held Plasma Device on Healthy Tissue Version 1.0 Protocol # NEO19-NV-01 05 November 2019
of collagen, amount of early collagen, migration of keratinocytes, bridging of cells, keratinization).
8.4 UNSCHEDULED VISITS
An unscheduled visit may be performed at any time during the study at the subject’s request or as deemed necessary by the site Investigator. The date and reason for the unscheduled visit will be recorded in the source documentation. If the unscheduled visit is the result of an adverse event, the event will be recorded on the adverse event CRF.
8.5 DATA REPORTING, COLLECTION AND MONITORING
The investigational device will be sent to the investigator by sponsor. The study site will require protocol and device training, which will be done by the Sponsor. The sponsor will monitor the site periodically during the duration of the study. Case Report Forms (CRFs) will be reviewed as will regulatory binders. The sponsor will collect all data at the completion of the study. The sponsor will list the study on clinicaltrials.gov as required by FDA regulations.
8.6 CONCOMITANT MEDICATIONS
All concomitant prescription medications taken during study participation will be recorded on the case
report forms (CRFs). For this protocol, a prescription medication is defined as a medication that can be
prescribed only by a properly authorized/licensed clinician. Other medications to be reported in the CRF
are concomitant over-the-counter medications and non-prescription medications, including vitamins and herbal supplements.
8.7 PROHIBITED MEDICATIONS, TREATMENTS OF PROCEDURES The use of immunosuppressive medications, antiplatelet medications, thrombolytics, anti inflammatory and anticoagulant medications are to be avoided (see section 5.2). The exception to this is acetaminophen (up to 3000 mg/daily) for local pain.
8.8 PROPHYLACTIC MEDICATIONS, TREATMENTS OR PROCEDURES None.
8.9 RESCUE MEDICATION, TREATMENTS OF PROCEDURES
In the event that the subject experiences pain, the principal investigator may recommend any analgesic deemed appropriate to the level of pain. Acetaminophen (up to 3000 mg daily) may be recommended for the pain associated with this treatment.

9 SAFETY REPORTING
9.1 DEFINITION OF ADVERSE EVENTS
Adverse event means any untoward medical occurrence associated with the use of an intervention in humans, whether or not considered intervention-related (21 CFR 312.32 (a)).
9.2 DEFINITION OF SERIOUS ADVERSE EVENTS (SAE)
NOTE: The term serious is not synonymous with severity, which may be used to describe the intensity of
an event experienced by the subject). An AE that does not meet any of the below criteria will be classified as non-serious.
A serious AE is any event that:
- Results in, or contributes to a death;
- Is immediately life threatening (injury or illness);
- Results in hospitalization, or prolongs an existing hospitalization;
- Results in permanent impairment of body structure or function, or in persistent or significant disability/incapacity;
- Results in an injury that requires medical intervention to prevent permanent impairment of body structure or function;
- Is a device malfunction or deterioration in the characteristics and/or performance of the device that results in death or serious deterioration in health;
- Is a device malfunction or deterioration in the characteristics and/or performance of the device that, if it were to occur again, could result in death or serious deterioration in health;
- Results in a congenital anomaly or birth defect.
- Is any medically significant injury, event or experience that requires medical/surgical intervention to prevent one of the outcomes listed above;
- Results in end organ toxicity, including hematological, renal, cardiovascular, hepatic, gastrointestinal, and central nervous system events
9.3 DEFINITION OF UNANTICIPATED PROBLEMS
This definition includes an unanticipated adverse device effect, any serious adverse effect on health or safety or any life-threatening problem or death caused by, or associated with, a device, if that effect, problem, or death was not previously identified in nature, severity, or degree of incidence in the investigational plan or application (including a supplementary plan or application), or any other unanticipated serious problem associated with a device that relates to the rights, safety, or welfare of subjects (21 CFR 812.3(s)).
25 of 38
Effects of Hand Held Plasma Device on Healthy Tissue Version 1.0 Protocol # NEO19-NV-01 05 November 2019
9.4 CLASSIFICATION OF AN ADVERSE EVENT
9.4.1 SEVERITY OF EVENT
For adverse events (AEs) not included in the protocol defined grading system, the following guidelines will be used to describe severity.
- Mild – Events require minimal or no treatment and do not interfere with the participant’s daily activities.
- Moderate – Events result in a low level of inconvenience or concern with the therapeutic measures. Moderate events may cause some interference with functioning. • Severe – Events interrupt a participant’s usual daily activity and may require systemic drug therapy or other treatment. Severe events are usually potentially life-threatening or incapacitating. Of note, the term “severe” does not necessarily equate to “serious”.]
9.4.2 RELATIONSHIP TO STUDY INTERVENTION
All adverse events (AEs) must have their relationship to study intervention assessed by the clinician who examines and evaluates the participant based on temporal relationship and his/her clinical judgment. The degree of certainty about causality will be graded using the categories below. In a clinical trial, the study product must always be suspect.
- Related – The AE is known to occur with the study intervention, there is a reasonable possibility that the study intervention caused the AE, or there is a temporal relationship between the study intervention and event. Reasonable possibility means that there is evidence to suggest a causal relationship between the study intervention and the AE.
- Not Related – There is not a reasonable possibility that the administration of the study intervention caused the event, there is no temporal relationship between the study intervention and event onset, or an alternate etiology has been established.
9.4.3 EXPECTEDNESS
Expected adverse reactions are AEs that are common and known to occur for the study agent being studied.
Adverse Events Associated with Electrocautery Treatment
Anticipated adverse events associated with electrocautery include mild and transient skin tenderness, minimal bleeding, erythema and edema lasting 1-3 days after treatment. Adverse Events Associated with Punch Biopsy
Anticipated adverse events associated with punch biopsy include tenderness, discomfort, edema, erythema, minimal bleeding, scarring and ecchymosis lasting 1-2 weeks after the procedure.
Adverse Events Associated with Surgical Marker
There are minimal risks associated with the use of a surgical marker but it may produce temporary erythema or contact dermatitis.
26 of 38
Effects of Hand Held Plasma Device on Healthy Tissue Version 1.0 Protocol # NEO19-NV-01 05 November 2019
Adverse Events Associated with Lidocaine
Anticipated adverse events associated mild and transient ecchymosis, erythema and edema. Resolution typically occurs soon after injection.
The site investigator or his/her designee will be responsible for determining whether an adverse event (AE) is expected or unexpected. An AE will be considered unexpected if the nature, severity, or frequency of the event is not consistent with the risk information previously described for the study intervention.
9.4.4 TIME PERIOD AND FREQUENCY FOR EVENT ASSESSMENT AND FOLLOW-UP The occurrence of an adverse event (AE) or serious adverse event (SAE) may come to the attention of study personnel during study visits and interviews of a study participant presenting for medical care, or upon review by a study monitor.
All AEs including local and systemic reactions not meeting the criteria for SAEs will be captured on the appropriate case report form (CRF). Information to be collected includes event description, time of onset, clinician’s assessment of severity, relationship to study product (assessed only by those with the training and authority to make a diagnosis), and time of resolution/stabilization of the event. All AEs occurring while on study must be documented appropriately regardless of relationship. All AEs will be followed to adequate resolution.
Any medical condition that is present at the time that the participant is screened will be considered as baseline and not reported as an AE. However, if the study participant’s condition deteriorates at any time during the study, it will be recorded as an AE.
Changes in the severity of an AE will be documented to allow an assessment of the duration of the event at each level of severity to be performed. AEs characterized as intermittent require documentation of onset and duration of each episode.
The site investigator or his/her designee will record all reportable events with start dates occurring any time after informed consent is obtained until 7 (for non-serious AEs) or 30 days (for SAEs) after the last day of study participation. At each study visit, the investigator will inquire about the occurrence of AE/SAEs since the last visit. Events will be followed for outcome information until resolution or stabilization.
9.5 ADVERSE EVENT REPORTING
All AEs will be recorded on the appropriate CRF and will include information about the start and stop dates, severity and relatedness. There should be an attempt to report a “diagnosis” rather than the individual signs, symptoms and abnormal laboratory values associated with the diagnosis. However, a diagnosis should be reported only if, in the Investigator’s judgment, it is relatively certain (i.e. definite or possible). Otherwise individual signs, symptoms and abnormal laboratory values should be reported as distinct adverse events.
27 of 38
Effects of Hand Held Plasma Device on Healthy Tissue Version 1.0 Protocol # NEO19-NV-01 05 November 2019
9.5.1 SERIOUS ADVERSE EVENT REPORTING
All serious AE, whether deemed expected or device related, must be reported to the sponsor immediately or within 24 hours by telephone (see contact details below).
Name: Jeff Allen
Phone: 1.954.629.9326
Email: Jeff@mintmedicalaesthetics.com
Address: 7460 NW 127th Terrace Parkland, FL 33076
A written report prepared by the Principal Investigator must follow within seven working days to the clinical monitor and should include a full description of the event and sequence. The study investigator shall complete a Serious Adverse Event / Serious Adverse Device Effect Form and submit to the study sponsor and to the reviewing IRB as soon as possible, but in no event later than 10 working days after the investigator first learns of the effect. The study sponsor is responsible for conducting an evaluation of an unanticipated adverse device effect and shall report the results of such evaluation to the FDA or local regulatory agency and to all reviewing IRBs and participating investigators within 10 working days after the sponsor first receives notice of the effect. Thereafter the sponsor shall submit such additional reports concerning the effect as the FDA or local regulatory agency requests.
9.5.2 UNANTICIPATED PROBLEM REPORTING
Incidents or events that meet the criteria for UPs require the creation and completion of an UP report form. It is the site investigator’s responsibility to report UPs to their IRB and to the study sponsor.
The UP report should include the following information:
- Protocol identifying information: protocol title and number, PI’s name, and the IRB project number;
- A detailed description of the event, incident, experience, or outcome; ● An explanation of the basis for determining that the event, incident, experience, or outcome represents an UP;
- A description of any changes to the protocol or other corrective actions that have been taken or are proposed in response to the UP.
Site investigator shall submit to the sponsor and to the reviewing IRB a report of any unanticipated adverse device effect occurring during an investigation as soon as possible, but in no event later than 10 working days after the investigator first learns of the effect (21 CFR 812.150(a)(1)), A sponsor who conducts an evaluation of an unanticipated adverse device effect under 812.46(b) shall report the results of such evaluation to Health Canada, the FDA or local regulatory agency and to all reviewing IRB’s and participating investigators within 10 working days after the sponsor first receives notice of the effect. Thereafter the sponsor shall submit such additional reports concerning the effect as FDA (21 CFR 812.150(b)(1)) or local regulatory agency requests.

Effects of Hand Held Plasma Device on Healthy Tissue Version 1.0 Protocol # NEO19-NV-01 05 November 2019
9.5.3 REPORTING OF PREGNANCY
If a subject becomes pregnant during the study, the subject will be terminated from the study as they no longer meet the eligibility criteria to participate in the study. The pregnancy will be immediately reported to the sponsor and to the IRB using the same reporting timelines as a SAE. The investigator will follow the pregnancy until completion and will report the outcome of the pregnancy to the sponsor on the Notification of Subject or Partner Pregnancy Outcome form and the IRB within 10 business days.
10 CLINICAL MONITORING
Clinical site monitoring is conducted to ensure that the rights and well-being of human subjects are protected, that the reported trial data are accurate, complete, and verifiable, and that the conduct of the trial is in compliance with the currently approved protocol/amendment(s), with GCP, and with applicable regulatory requirement(s).
- Monitoring for this study will be performed by the sponsor or designate. • On-site monitoring will occur within 10 weeks of first enrolled subject and will occur at a frequency described in the Monitoring Plan.
- Variables to be monitored will be described in the Monitoring Plan.
- The Study Director or designate will be provided copies of monitoring reports within 15 business days of visit.
11 STATISTICAL ANALYSIS
11.1 SAMPLE SIZE DETERMINATION
A total sample size of 5 healthy volunteers will be investigated. This number of subjects is justified as the primary objective is to profile the wound healing and tissue injury profile. No formal power calculation was performed given the exploratory character of the study.
11.2 DESCRIPTION OF STATISTICAL METHODS
Endpoints will be summarized using descriptive statistics including mean score, standard deviation, standard error and range. Frequency and percentage of subjects within each category will be presented for categorical data. If applicable, Wilcox t-test may be used to determine if two sets of data are significantly different from one another. If p-value is below the level of statistical significance for effectiveness analyses (α = 0.05) for all tests of differences, then the null hypothesis is rejected in favor of the alternative hypothesis. Rejection of null hypotheses will establish that:
- The two-sided 95% confidence interval for the difference between the means excludes zero.
- The two means are statistically significantly different at the 5% level (P < 0.05) two sided.
29 of 38
Effects of Hand Held Plasma Device on Healthy Tissue Version 1.0 Protocol # NEO19-NV-01 05 November 2019
Upon rejection of null hypotheses, further statistical test tools such as, Confidence Interval, and/or One- way ANOVA and/or descriptive statistical tools may be used to determine the performance of the treatment.
11.2.1 SAFETY ANALYSES
The safety analysis will be done by analyzing spontaneous reports of adverse events (AE),as well as analysis of immediate response reports by the principal investigator from his/her observation/examination of the treated area. Appropriate Medical Dictionary for Regulatory Activities (MedDRA) code will be used to describe all spontaneously reported events or other study related adverse events.
Summaries of spontaneously reported or other study related adverse events will be presented as:
- Number (%) of subjects with any AE
- Number (%) of subjects with any serious adverse events (SAE)
- Number (%) of subjects permanently withdrawn from treatment due to AE Summaries of analysis of immediate response reports by the principal investigator examination will be displayed on a bar or pie chart and/or a table as;
- the overall frequency of subjects with each event (pain during treatment, hemorrhage, burn, erythema, edema, purpura, etc.)
- Frequency of subjects with specific severity/intensity for each event using a 5- point scale: 1=none; 2=trace; 3=moderate; 4=marked; 5=severe
- The overall proportion of subjects observed with marked or severe intensity of any event will be calculated and compared to those with none, trace or
moderate severity/intensity
11.2.2 BASELINE DESCRIPTIVE STATISTICS
Subjects baseline demographics will be compared using descriptive statistics such as mean score, standard deviation, standard error and range. Data will be displayed in tables or graphical presentation.
12 MEASURES TO MINIMIZE BIAS
12.1 ENROLLMENT/RANDOMIZATION/MASKING PROCEDURES
At screening, once a subject has signed the informed consent, and inclusion/exclusion criteria has been met, a unique subject number will be assigned. The identifying number will be composed of a two-digit site number and a three-digit subject number in sequence. This unique identifier will be used throughout the entire study and will be entered in the subject’s case report form (CRF) and for each treatment.
In this clinical study trial subjects will not be randomized; this is an open-label, baseline controlled, evaluator-blinded study; Only the independent reviewers/pathologists will be blinded.
30 of 38
Effects of Hand Held Plasma Device on Healthy Tissue Version 1.0 Protocol # NEO19-NV-01 05 November 2019
13 SUPPORTING DOCUMENTATION AND OPERATIONAL CONSIDERATIONS Each participating site will maintain appropriate medical and research records for this trial, in compliance with ICH E6, ISO 14155:2011, HIPAA and regulatory and institutional requirements for the protection of confidentiality of participants. Each site will permit authorized representatives of the study sponsor and regulatory agencies to examine (and when permitted by applicable law, to copy) clinical records for the purposes of quality assurance reviews, audits, and evaluation of the study safety, progress, and data validity.
Source data are all information, original records of clinical findings, observations, or other activities in a clinical trial necessary for the reconstruction and evaluation of the trial. Examples of these original documents and data records include, but are not limited to, hospital records, clinical and office charts, laboratory notes, memoranda, participants’ memory aids or evaluation checklists, pharmacy dispensing records, recorded audio tapes of counseling sessions, recorded data from automated instruments, copies or transcriptions certified after verification as being accurate and complete, microfiches, photographic negatives, microfilm or magnetic media, x rays, and participant files and records kept at the pharmacy, at the laboratories, and medico technical departments involved in the clinical trial.
It is acceptable to use CRFs as source documents. Demographic data, medical/surgical history, adverse event reporting and procedural notes will be collected on the CRFs with the remainder collected from other sources. It is not acceptable for the CRF to be the only record of a subject’s participation in the study. This is to ensure that anyone who would access the patient medical record has adequate knowledge that the patient is participating in a clinical trial.
14 QUALITY ASSURANCE AND QUALITY CONTROL
Prior to any independent use of the Nu-VissaTM investigational device, study personnel will receive proper training from the sponsor. Site personnel will be trained on the use of the device prior to study initiation at the site. Additional training requirements will be discussed during study initiation and will include site responsibilities, study reporting and study documentation. In addition, the sponsor will provide protocol specific training for site personnel. The site will document which individual has been assigned to a specific task and will ensure that appropriate training has occurred for that task.
Regular monitoring and an independent audit, if conducted, may be performed according to ICH-GCP and ISO 14155:2011.
Quality control (QC) procedures will be implemented beginning with the data entry monitoring and data quality control checks. Any missing data or data anomalies will be communicated to the site(s) for clarification and resolution. Monitors will verify that the clinical trial is conducted and data are generated, documented (recorded), and reported in compliance with the protocol, GCP, and the applicable regulatory requirements.
31 of 38
Effects of Hand Held Plasma Device on Healthy Tissue Version 1.0 Protocol # NEO19-NV-01 05 November 2019
The investigational site will provide direct access to all trial related materials, source data/documents, and reports for the purpose of monitoring and auditing by the sponsor, and inspection by local and
regulatory authorities.
15 ETHICAL CONSIDERATIONS AND PROTECTION OF HUMAN SUBJECTS
15.1 ETHICAL STANDARD
The investigator will ensure that this study is conducted in full conformity with Regulations for the Protection of Human Subjects of Research codified in 45 CFR Part 46, 21 CFR Part 50, 21 CFR Part 56, and/or the ICH E6, the Declaration of Helsinki, Council for International Organizations of Medical Science (CIOMS) and ISO 14155:2011.
15.2 INSTITUTIONAL REVIEW BOARD
The protocol, informed consent form(s), recruitment materials and all participant materials must be submitted to the IRB for review and approval. Approval of both the protocol and the consent form must be obtained before any participant is enrolled and study is initiated. Any amendment to the protocol requires review and approval by the IRB before the changes are implemented to the study. All changes to the consent form must be IRB approved; a determination will be made regarding whether previously consented participants need to be re consented at that time.
15.2.1 PROTOCOL DEVIATION
A protocol deviation is any noncompliance with the clinical trial protocol, International Conference on Harmonization Good Clinical Practice (ICH GCP), or Manual of Procedures (MOP) requirements. The noncompliance may be either on the part of the participant, the investigator, or the study site staff. As a result of deviations, corrective actions are to be developed by the site and implemented promptly.
These practices are consistent with ICH GCP:
- 4.5 Compliance with Protocol, sections 4.5.1, 4.5.2, and 4.5.3
- 5.1 Quality Assurance and Quality Control, section 5.1.1
- 5.20 Noncompliance, sections 5.20.1, and 5.20.2.
It is the responsibility of the site investigator to use continuous vigilance to identify and report deviations within 10 working days of identification of the protocol deviation, or within 10 working days of the scheduled protocol-required activity. All deviations must be addressed in study source documents. Protocol deviations must be sent to the reviewing Institutional Review Board (IRB) per their policies. The site investigator is responsible for knowing and adhering to the reviewing IRB requirements. Further details about the handling of protocol deviations will be included in the MOP.
32 of 38
Effects of Hand Held Plasma Device on Healthy Tissue Version 1.0 Protocol # NEO19-NV-01 05 November 2019
15.3 INFORMED CONSENT PROCESS
Informed consent is a process that is initiated prior to the individual’s agreeing to participate in the study and continues throughout the individual’s study participation. Consent forms will be Institutional Review Board (IRB)-approved and the participant will be asked to read and review
the document. The investigator will explain the research study to the participant and answer any questions that may arise. A verbal explanation will be provided in terms suited to the participant’s comprehension of the purposes, procedures, and potential risks of the study and of their rights as research participants. Participants will have the opportunity to carefully review the written consent form and ask questions prior to signing. The participants should have the opportunity to discuss the study with their family or surrogates or think about it prior to agreeing to participate. The participant will sign the informed consent document prior to any procedures being done specifically for the study. Participants must be informed that participation is voluntary and that they may withdraw from the study at any time, without prejudice. A copy of the informed consent document will be given to the participants for their records. The informed consent process will be conducted and documented in the source document (including the date), and the form signed, before the participant undergoes any study-specific procedures. The rights and welfare of the participants will be protected by emphasizing to them that the quality of their medical care will not be adversely affected if they decline to participate in this study.
15.4 CONFIDENTIALITY AND PRIVACY
Participant confidentiality and privacy is strictly held in trust by the participating investigators, their staff, and the sponsor(s) and their interventions. This confidentiality is extended to cover testing of biological samples and genetic tests in addition to the clinical information relating to participants. Therefore, the study protocol, documentation, data, and all other information
generated will be held in strict confidence. No information concerning the study or the data will be released to any unauthorized third party without prior written approval of the sponsor.
All research activities will be conducted in as private a setting as possible.
The study monitor, other authorized representatives of the sponsor, representatives of the Institutional Review Board (IRB), regulatory agencies may inspect all documents and records required to be maintained by the investigator, including but not limited to, medical records (office, clinic, or hospital) and laboratory records for the participants in this study. The clinical study site will permit access to such records.
The study participant’s contact information will be securely stored at each clinical site for internal use during the study. At the end of the study, all records will continue to be kept in a secure location for as long a period as dictated by the reviewing IRB, Institutional policies, or sponsor requirements.
Study participant research data, which is for purposes of statistical analysis and scientific reporting, will be transmitted to and stored at the Sponsor location. This will not include the
33 of 38
Effects of Hand Held Plasma Device on Healthy Tissue Version 1.0 Protocol # NEO19-NV-01 05 November 2019
participant’s contact or identifying information. Rather, a unique study identification number will identify individual participants and their research data. The study data entry and study management systems used by clinical sites and by NuVissa research staff will be secured and password protected. At the end of the study, all study databases will be de-identified and archived at the Sponsor’s location.
15.5 FUTURE USE OF STORED SPECIMENS AND DATA
Data collected for this study will be analyzed and stored at the Sponsor’s location
Research participants may request withdrawal/destruction of their tissue samples up until the time that samples are used for histology analysis by asking a study investigator. Should any research participants withdraw from study participation, they will be specifically asked if their collected samples may be studied per protocol. During the duration of the study, an individual participant can choose to withdraw consent to have biological specimens stored for future research. However, withdrawal of consent with regard to bio sample storage may not be possible after the study is completed.
15.6 DATA COLLECTION AND RECORD KEEPING
15.6.1 DATA COLLECTION AND MANAGEMENT RESPONSIBILITIES
Data collection is the responsibility of the clinical trial staff at the site under the supervision of the site investigator. The investigator is responsible for ensuring the accuracy, completeness, legibility, and timeliness of the data reported.
All source documents should be completed in a neat, legible manner to ensure accurate interpretation of data.
Hardcopies of the study visit worksheets will be provided for use as source document worksheets for recording data for each participant enrolled in the study. Data recorded in the electronic case report form (eCRF) derived from source documents should be consistent with the data recorded on the source documents.
Clinical data (including adverse events (AEs), concomitant medications, and expected adverse reactions data) and clinical laboratory data will be entered into excel spreadsheets a 21 CFR Part 11-compliant data capture system provided by the Sponsor. The data system includes password protection and internal quality checks, such as automatic range checks, to identify data that appear inconsistent, incomplete, or inaccurate. Clinical data will be entered directly from the source documents.
15.6.2 STUDY RECORDS RETENTION
Study documents should be retained for a minimum of 2 years after the last approval of a marketing application in an International Conference on Harmonization (ICH) region and until
34 of 38
Effects of Hand Held Plasma Device on Healthy Tissue Version 1.0 Protocol # NEO19-NV-01 05 November 2019
there are no pending or contemplated marketing applications in an ICH region or until at least 2 years have elapsed since the formal discontinuation of clinical development of the study
intervention. These documents should be retained for a longer period, however, if required by local regulations. No records will be destroyed without the written consent of the sponsor, if applicable. It is the responsibility of the sponsor to inform the investigator when these
documents no longer need to be retained.
15.7 CONFLICT OF INTEREST POLICY
The independence of this study from any actual or perceived influence is critical. Therefore, any actual conflict of interest of persons who have a role in the design, conduct, analysis,
publication, or any aspect of this trial will be disclosed and managed. Furthermore, persons who have a perceived conflict of interest will be required to have such conflicts managed in a way that is appropriate to their participation in the design and conduct of this trial. The study
leadership has established policies and procedures for all study group members to disclose all conflicts of interest and will establish a mechanism for the management of all reported dualities of interest.
