Summary
Brief summary (as posted)
The purpose of this study is to determine if the Nanopulse System can be used to clear common wart lesions on the skin. The Nanopulse System uses a series of low energy, high voltage pulses, each one several billionths of a second in duration, to effectively kill the target tissue contained within the applicator tip electrodes with minimal damage to surrounding tissue. Efficacy and patient outcomes are expected to equal or surpass current treatment modalities in terms of increased ease of use, faster patient healing and minimal scarring with fewer complications resulting from treatment. The device emits significantly less energy than existing electro-surgery or electro-cautery equipment and is believed to be similar to laser therapy treatment of warts. Trained clinicians can usually diagnose warts based by their appearance and location . Non-genital warts are subcategorized into common, periungual, flat, filiform, and plantar types. Common warts are benign, often skin-colored, or brown-grey, rough, bumpy growths on the hands and feet (caused by Human Papilloma Virus type 2) . Common warts in individuals without any immune deficiencies are low risk and are the focus of this study.Based upon the preclinical profile of the Nanopulse device, particularly its safety profile and its effect on transformed cells, it is hypothesized that application of pulses from the Nanopulse System , will result in complete clinical clearance of Common Wart lesions with minimal scarring.

- description
- The study will be a single center, open label, non-randomized clinical trial that will provide efficacy data for the treatment of common warts by the Nanopulse system in terms of efficacy and cosmetic outcome with 1 - 4 application (treatment) sessions. All subjects will receive a minimum number of applications per discrete skin wart lesion. Up to 4 warts per subject will be treated with the Nanopulse device. The wart will be debulked to the point of pinpoint bleeding prior to the initial application. The subject will return after 1 week for an evaluation visit and at 4 weeks for a second treatment and 2 additional monthly treatments if warranted. If the subject is declared clinically clear at any of the application visits, they will be placed into follow up. The minimum number of treatments per wart is one and the maximum is 4. They will return at the 12 week point post last visit for final assessment and evaluation.

- description
- Response rate is defined in each case in terms of no effect (NE=2), partial response (PR=1), or complete response (CR=0). No Effect (NE) would indicate no clinically apparent reduction in lesion size, Partial Response (PR) would indicate a reduction in lesion size, and Complete Response (CR) would indicate no evidence of the lesion detected.

Inclusion Criteria: * Only Common Warts will be included as study lesions. * Only discrete common warts in a single 5cm x 5cm anatomical area can be included as study lesions. Up to 4 discrete common warts that meet this criteria can be treated per subject. The 5cm x 5cm area must not have more than 2 warts present at the time of screening and warts outside each area must be at least 2cm away from warts included as study lesions. Please Note: A single digit (e.g. finger) can represent a 5cm x 5cm area, and a lesion within the area can be included as a study lesion UNLESS it is on the inside surface of a digit where there are wart lesions present on the surface of an adjacent digit that would be within 1 cm of touching the potential study lesion when the surfaces of the digits are in contact with one another. * Subject's lesion may have been treated with over-the-counter treatments, but not by any prescription medicine, surgery, or destructive procedure (i.e., cryotherapy) within four weeks of the date the subject is recruited into the study. * Subject's wart and the subject must be suitable candidates for usual Standard of Care treatments. Standard of care for common warts is defined as curettage and electrodesication, cryotherapy, topical therapy or surgery. * Subject must be competent to provide informed consent. * If the subject is female, and of childbearing potential, subject must be actively practicing a clinically acceptable form of birth control. * Subject's medical evaluation during their screening visit does not indicate any findings of clinical significance relevant to participating in study. * Subject has been informed of their options for standard of care for the lesion type outside of the study. Exclusion Criteria: * Subjects not meeting all inclusion criteria should be excluded. * Subjects who have lesions within the 5cm x 5cm anatomical area under study which are painful or have been noticeably changing just prior to the time of screening. * Periungual warts are excluded from the study as study lesions. Subject is to be informed that these warts will not be treated during the duration of the study. * Lesions on the face are excluded from the study as study lesions. * Lesions which are diagnosed as flat warts, filiform warts, plantar warts, and genital warts are excluded from the study as study lesions. Subject is to be informed that these warts will not be treated during the duration of the study. * Subjects who are using or intend to use any other warts therapy concomitantly during the study period or within 4 weeks of their screening visit. * Subjects who are not capable of undergoing surgical standard of care treatment for common warts due to mental or physical limitations. * Subjects in whom a minor surgical procedure is contraindicated (e.g. under advice of their own caring clinician). * Subjects who have an implanted artificial heart valve or other prosthesis requiring prophylactic antibiotic coverage for minor surgical procedures. * Subjects who have an implanted cardiac pacer or defibrillator or other similar life sustaining implanted electrical device. * Subjects who have had any cosmetic or therapeutic procedure (e.g. use of liquid nitrogen, surgical excision, curettage, dermabrasion, medium or greater depth chemical peel, laser resurfacing) within 2cm of targeted area and margins within 4 weeks of the screening visit and within 10cm of treatment area during the study. * Subjects who are immunosuppressed either due to an existing medical diagnosis, or are currently using medications that suppress the immune system (e.g. cyclosporine, prednisone, methotrexate, alefacept, infliximab) or have used these medications within 8 weeks of the screening visit or anytime during the study. * Topical immunomodulators (imiquimod, steroid creams) within 4 weeks of the screening visit or any time during the study. * Prolonged or excessive exposure to ultra-violet light within 2 weeks prior to screening visit or any time during the study. * Subjects who, if female, know that they are currently pregnant or are lactating and actively breastfeeding. * Under the Investigator's authority to exclude any participant at his/her discretion, participation in this study is not recommended for this Subject.
