Summary

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.

Interventions

DEVICE

Nanopulse System

The Nanopulse System consists of an electrical pulse generator, a handpiece, and a detachable applicator tip at the end of the handpiece that interfaces with the treatment area on the skin. The detachable applicator tip delivers the pulses to the skin through five 3 mm long needle electrodes (27 gauge). The applied electric field, is limited to the space enclosed by the 4 outer electrodes in the applicator tip. An inert, water based gel is applied to the skin and the applicator tip before making contact between subject and applicator tip to ensure that there are no air gaps present between the electrodes through which electrical arcing could occur while pulses are being delivered to the subject. The Applicator Tips are designed for single patient use, and are sterilized prior to first use and between treatment sessions using a standard steam autoclave.
