Stability of diagnostic blood and saliva biomarkers in healthy adults

Clinical Study on Healthy Volunteers for Validating the Stability of Different Diagnostic Biomarkers Studied at Firalis

Not applicable Interventional Firalis SA · NCT05160337

This tests whether different blood and saliva biomarkers (lncRNAs, sncRNAs, mRNAs, proteins, lipids, metabolites) stay stable over time in healthy adults and whether age, sex, or recent nutrition change their levels.

What this trial studies

Firalis will enroll healthy volunteers aged 18–85 to provide blood and other peripheral samples at its Clinical Investigation Center in Huningue. Collected samples will be anonymized and analyzed for long non-coding RNAs, small non-coding RNAs, messenger RNAs, circulating proteins, lipids, and metabolites to measure stability across repeat collection times. The study will record participant age, sex, and recent nutritional status to determine how these factors influence biomarker expression. Results will be used for the analytical validation of Firalis' in‑vitro diagnostic test candidates.

Who should consider this trial

Good fit: Healthy adults 18–85 who can give informed consent, comply with study procedures, and meet the minimum weight thresholds (males >50 kg, females >40 kg) are the ideal participants.

Not a fit: Individuals with active medical conditions, those seeking therapeutic benefit, minors, or people unable to travel to the single Huningue site will not receive direct clinical benefit from participating.

Why it matters

Potential benefit: If successful, the results could improve the reliability and clinical readiness of Firalis' diagnostic tests by identifying which biomarkers are stable and how demographic or dietary factors affect measurements.

How similar studies have performed: Biomarker stability and preanalytic effect studies are a common, established part of diagnostic validation and have been used successfully in prior diagnostic development programs.
