Brief Summary:
The primary purpose of this trial is to evaluate Nano-Pulse Stimulation (NPS) to clear or remove Seborrheic Keratosis (SK) lesions from off-facial areas of healthy adult subjects.

Condition or disease Intervention/treatment Phase
Lesion Skin Seborrheic Keratosis Device: Nano-Pulse Stimulation (NPS) Not Applicable

Detailed Description:

Evaluate Nano-Pulse Stimulation (NPS) to clear or remove Seborrheic Keratosis (SK) lesions from off-facial areas of healthy adult subjects.

The specific objectives of this study are to:

  • Document the non-treated appearance of off-face SKs.
  • Evaluate the clearance of SKs in off-face locations post-treatment versus pre-treated appearance of the same lesion.
  • Evaluate the clearance of the treated SKs at various points in time over several weeks following the initial procedure, compared to the pre-treated SKs.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 60 participants
Allocation: Non-Randomized
Intervention Model: Sequential Assignment
Intervention Model Description: Each subject served as their own control. Each subject had 4 lesions with 3 of the lesions serving in the Active Comparative Arm (Lesions treated with Nano-Pulse Stimulation) and 1 lesion serving as control not treated with Nano-Pulse Stimulation and assigned to No Intervention Arm.
Masking: Single (Outcomes Assessor)
Masking Description: A Reference Key was developed for 3 independent reviewers to use during their review of the full set (196 image pairs) of study photographs. The reference key included 2 representative photographs for each of the 4 possible scores used in the SK study (clear, mostly clear, partially clear, and not clear). The three independent reviewers were not principal investigators at enrolling centers.
Primary Purpose: Treatment
Official Title: Evaluation of Nano-Pulse Stimulation (NPS) in Patients With Seborrheic Keratosis
Actual Study Start Date : May 4, 2017
Actual Primary Completion Date : November 13, 2017
Actual Study Completion Date : May 22, 2018

Arm Intervention/treatment
Active Comparator: Nano-Pulse Stimulation (NPS) Lesion
Three of four selected SK lesions receive Nano-Pulse Stimulation treatment.
Device: Nano-Pulse Stimulation (NPS)
The Pulse generator delivers electrical pulses (nanosecond duration) that are applied directly to targeted lesion using sterile treatment tips with micro-needles.

No Intervention: Non-Treated Lesion
One of four SK lesions is randomized to not receiving Nano-Pulse Stimulation treatment.

Primary Outcome Measures :
  1. SK Lesion Clearance [ Time Frame: 106-day post-treatment ]
    Degree of clearance of SK lesions treated with NPS as rated by an independent reviewer's assessment of photographs of the lesions.
