About

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.

Full 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.

Enrollment: 150 patients

Sex: All

Ages: 22 to 80 years old

Volunteers: No Healthy Volunteers

• 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.

• 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.
