About this trial

This is an interventional treatment trial for Warts focused on measuring CellFX, Nano-Pulse Stimulation, NPS, Clearance, Wart Reduction

Eligibility Criteria

22 Years - 80 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Subjects must be at least 21 and not older than 80 years of age
  • Subject has a Fitzpatrick Skin Type I, II, III or IV.
  • Subject gives voluntary, written informed consent to participate in this clinical investigation and from whom consent has been obtained.
  • Subject must comply with study procedures including all follow-up visits.
  • Subject is willing to have warts treated in a single treatment session and understands that their warts may undergo multiple treatment sessions at subsequent visits.
  • Subject must have a minimum of 2 warts and up to 8 warts to be treated.
  • Subject with a clinical diagnosis of common warts located on hands and fingers or other body areas that are not located on the scalp, nose, within the orbital region of the face, plantar, genital or periungual area.
  • For study purposes, the warts must be no greater than 3 mm in height and must not exceed 10mm x 10mm at their largest dimension.
  • Each wart must appear alone and discrete and not appear in clusters.
  • Each wart must have been present for at least 4 weeks.
  • Subject consents to have photographs taken of the warts.
  • Subject agrees to refrain from using all other wart removal products or treatments (e.g.

topical medication including over-the-counter medications) during the study period.

Exclusion Criteria:

  • Subject with more than 8 visible warts in total anywhere on the body.
  • Subject has flat, periungual, subungual, genital, anal, mosaic, plantar or filiform warts.
  • Subject has an implantable electronic medical device.(i.e., pacemaker, implantable cardioverter defibrillator)
  • Subject has an active infection or history of infection in designated test area within 90 days prior to first treatment.
  • Subject is taking antihistamines, including those used for gastric symptoms.
  • Subject is prone to Koebnerization or has any of the following conditions (e.g., psoriasis, vitiligo, lichen planus, or an autoimmune disorder of the skin)
  • Subject is not willing or able to sign the Informed Consent.
  • Subject is known to be immune compromised.
  • Subject has allergies to Lidocaine or Lidocaine-like products.
  • Subject is a member of a vulnerable population including individuals employed by the
  • Sponsor, clinic site, or entity associated with the conduct of the study.
  • Have any condition or situation which, in the Investigator's opinion, puts the subject at significant risk, could confound the study results, or may interfere significantly with the subject's participation in the study.
  • Use of any other investigational drug, therapy, or device within the past 30 days of enrollment or concurrent participation in another research study.
  • Subject was previously treated with CellFX for warts.

CellFX device using pre-defined energy protocols

Cryosurgery will be standardized across all investigational sites. Investigators will perform the Cryosurgical procedure using the Brymill Cry-Ac B700 Liquid Nitrogen Sprayer.

Outcomes

Primary Outcome Measures

Wart Clearance
The primary effectiveness endpoint is wart clearance, defined as "resolved" versus "not resolved" based on the classification of the blinded site investigator.
Wound Healing
The wound healing safety endpoint is the presence or absence of a wound healing event defined as the presence of scabbing, swelling, crusting, blister, scar or ulcer assessed by the blinded site investigator.
Adverse Skin Change
The skin change safety event is defined as the presence of hyperpigmentation, hypopigmentation, or scarring as assessed by the blinded site investigator.

Secondary Outcome Measures

Wart Resolution
Wart resolution will be assessed by three independent observers, blinded to treatment assignment, who will classify the response for each wart as "resolved" or "not resolved" based on photographs.

5. Study Description

Brief Summary
This prospective, multicenter, single-blinded, randomized comparison study is designed to compare the safety and effectiveness of the CellFX System to Cryosurgery for the clearance of cutaneous non-genital common warts on all areas of the body excluding the scalp, nose, within the orbital region of the face, plantar or periungual area in healthy adult subjects.
Detailed Description
The study will enroll healthy adult subjects with a minimum of two cutaneous non-genital warts, excluding the face, with each wart lesion not exceeding 10 x 10mm. Macrophotography of all study warts will be captured along with a blinded site Investigator to characterize wart healing, wart clearance and wart reduction. All subjects will be followed at 7, 30, 60, and 90-days following the last CellFX or Cryosurgical Procedure. All wart lesions are eligible for up to a total of 3 treatments over the course of the study. Adverse events will be documented.
