Meet Replior at EADV Congress 2026

Measure what patients can't report

Europe’s leading congress on skin and sexual health returns to Vienna, bringing together more than 20,000 delegates across four days of science, practice and innovation. We’ll be there with both of our clinical-grade ring sensors — ScratchSense and RaySense — and the trial platform behind them.

About the EADV CONGRESS

The annual EADV Congress is the largest gathering in European dermato-venereology, covering the full spectrum of the specialty through plenary lectures, hands-on workshops, sub-specialty sessions and late-breaking science. The 2025 edition in Paris drew over 20,000 delegates; the 2026 edition runs 30 September to 3 October at Messe Wien in Vienna.

Dermatology research is moving past self-report

Regulators still require the patient’s voice, and rightly so. But asking someone to recall how much they scratched last night, or how much sun they got last week, means measuring efficacy through the filter of human memory. That recall bias shows up as intrapatient variance — and variance is usually solved by enrolling more patients, which is slow and expensive.

There is a better lever. Objective, continuous, device-reported data alongside patient-reported outcomes gives you the full picture: how patients feel and what actually happened.

Replior’s sensor platform enables:

Objective measurement of scratching behaviour, intensity and sleep quality
Continuous, real-world light-exposure data outside of clinic visits
High-resolution insight into treatment response night by night, day by day
PROs strengthened by sensor-based evidence, not replaced by it
Lower data variance — supporting smaller studies with higher statistical confidence

“We believe the future of clinical research lies in achieving a balance between patient-reported outcomes and objective sensor data. Listening to how patients feel and experience treatment remains essential, but combining these insights with unbiased, device-reported data allows researchers to gain a fuller, more reliable understanding of patient health and trial outcomes.”

ScratchSense — objective scratch and sleep data for pruritus trials

Subjective itch scores are noisy. Patients forget, underestimate, and scratch unconsciously during sleep. ScratchSense is a clinical-grade ring sensor that quantifies scratching behaviour and sleep quality continuously, 24 hours a day — with an on-device neural network that transmits genuine scratch events and ignores everything else.

Seven dimensions per scratch event: duration, frequency (Hz), force (N), amplitude, nail involvement and more
Sleep metrics including sleep onset, total sleep time, sleep efficiency and scratch bouts per hour
Fully passive — no buttons, no diaries, no recall
Built for Atopic Dermatitis, Chronic Prurigo and Chronic Spontaneous Urticaria trials

RaySense — continuous light-exposure data for dermatology and photosensitivity studies

UV exposure shapes inflammation, pigmentation and treatment response, yet patient sun behaviour is rarely measured objectively. In dermatology and photosensitivity studies it is often the most consequential uncontrolled variable in the protocol. RaySense turns it into a measurable, audit-ready covariate.

UVA/UVB and UV Index, visible light across RGB channels, and infrared — updated every two minutes
Up to 350 days of continuous battery life
Protocol-configurable thresholds with real-time alerts as participants approach exposure limits
Ennova Health 2023 winner, IoT category (e-Health, Wearables & Robotics)
Used in dermatology and cosmetics research, EPP, XP, PLE, lupus and oncology studies

Come and try them on. Find us in booth X2110

Both sensors will be at the booth — wear them, handle them, and see live data land in the dashboard. Our team will be there all four days to talk through protocol fit, endpoint strategy and what objective scratch and light data could do for your study design.
