Trial Outcomes & Findings for Nano-Pulse Stimulation (NPS) in Sebaceous Hyperplasia (NCT NCT03612570)

NCT ID: NCT03612570

Last Updated: 2024-04-12

Results Overview

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.

Nano-Pulse Stimulation Device using pre-defined energy protocol 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.

PRIMARY outcome

Timeframe: 60-days follow-up post-last treatment

Population: Total number of treated SH Lesions at 60-days.

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.

Nano-Pulse Stimulation (NPS) treated SH Lesions using pre-defined treatment levels. All adverse events were recorded per lesion.
Skin and subcutaneous tissue disorders
Post-Inflammatory Hyperpigmentation
45.1%
32/71 • Number of events 32 • Skin effects (hyperpigmentation) were observed per SH lesion at the 5-day, 30-day, 60-day and if applicable 90-day follow-up periods.
Skin effects per SH lesion were defined as presence of mild, moderate or severe post-inflammatory hyperpigmentation (PIH).
