Microneedle-based ISF Sampling Technique
A study testing PELSA System in people with No Condition, Healthy Individuals, run by Ascilion AB at 1 site in Germany.
Trial summary
This clinical investigation aims to evaluate the performance and safety of the PELSA system, a hollow microneedle-based medical device designed for the collection of dermal interstitial fluid (dISF) from human skin. Healthy adult volunteers will undergo a single dISF sampling session using the PELSA system. Read more about this study

About this study
Official title: Clinical Investigation of the PELSA Microneedle-Based Device for Dermal Interstitial Fluid Sampling in Healthy Adults: Assessment of Performance and Safety
This clinical investigation aims to evaluate the performance and safety of the PELSA system, a hollow microneedle-based medical device designed for the collection of dermal interstitial fluid (dISF) from human skin.
Healthy adult volunteers will undergo a single dISF sampling session using the PELSA system. The primary objective is to assess the proportion of participants from whom at least 1 µL of dISF can be successfully collected during one sampling session.
Device safety and tolerability will also be evaluated, including the occurrence of adverse events, participant-reported pain, and local skin reactions. Exploratory assessments may include glucose detection and proteomic analysis of collected dISF samples.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PELSA SystemDevice
Also called PELSA, Hollow Microneedle Sampling System
The PELSA system is a medical device designed to collect dermal interstitial fluid (dISF) using an array of hollow microneedles and controlled subpressure. The procedure involves applying the microneedle array to the skin, followed by extraction and collection of dISF into a capillary tube. Each participant undergoes one sampling session lasting approximately 15 minutes, during which sampling performance, safety, and tolerability are evaluated.
| Study group | Role | What they receive |
|---|---|---|
| PELSA Dermal Interstitial Fluid Sampling | Experimental | Participants will undergo one dermal interstitial fluid sampling session using the PELSA system. The device employs an array of hollow microneedles and controlled subpressure to collect dermal interstitial fluid from the skin. Sampling performance, safety, and participant tolerability will be assessed. Receives: Device: PELSA System |
What is being measured
The primary outcome is the main question the study is designed to answer.
Successful Collection of Dermal Interstitial Fluid
Proportion of participants with successful collection of at least 1 µL of dermal interstitial fluid during one PELSA sampling session. The success proportion and its 95% confidence interval will be calculated.
Measured: During the sampling session
