Clinical Trial Summary

This prospective, open label, muti-center study evaluates the use of Nano-Pulse Stimulation (NPS) in the treatment of Sebaceous Hyperplasia (SH) lesions less than 2.5mm in size.

Description:

The study is designed with each subject serving as his or her own control. A total of up to 75 subjects with 2-5 qualifying SH lesions will be enrolled and treated with either a 1.5-mm x 1.5-mm or 2.5-mm x 2.5-mm tip. All treated lesions will receive at least one NPS treatment and evaluated at 30 days for lesion clearance. Initial lesions scored as Not Clear or Partially Clear may undergo a second NPS treatment. All subjects will have their lesions evaluated at 60 days post-primary or secondary treatment.

Eligibility

Inclusion Criteria:

• Active infection or history of infection in designated test area within 90 days prior to study initiation

• Use of oral steroid and/or retinoid use within the last 12 months

• Prior treatment to the identified SH lesions targeted for the study which occurred within 6 months prior to study start

• Is known to be immune-compromised and/or received immunosuppressant therapy within 6 months prior to study start

• Taking blood thinning medications

Intervention

Device:
• Nano-Pulse Stimulation Device
NPS utilizes a timed series of low energy, high voltage nanosecond (billionth of a second) pulses which are applied directly to targeted tissue using small microneedles. NPS energy induces cell signaling and the activation of cellular pathways by creating transient nanopores in cellular membranes and organelles and initiate regulated cell death.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Total Number of Cleared SH Lesions	SH lesion clearance was assessed live by investigators for each treated SH lesion (n=222) at 60-days post-last treatment using a 4-point scale (i.e., 0, 1, 2, 3) where each number corresponded to Clear, Mostly Clear, Partially Clear, or Not Clear, respectively. Lower scores mean better outcome, i.e., 0=Clear while a 3=Not Clear.	60-days follow-up post-last treatment
