SLEEP IN CLINICAL TRIALS

Sleep matters in trials.
Recording it shouldn't be the bottleneck.

01

As a primary endpoint

In insomnia, narcolepsy, restless legs, and circadian disorders.

02

As a biomarker

In neurology and psychiatry, tracking disease progression and treatment response.

03

As a covariate

In pain, oncology, metabolic, and cardiology trials, controlling for a major source of variance.

SLEEP IN CLINICAL TRIALS

Optimized for the
signals that matters

Whether sleep is your primary endpoint or a secondary measure, our EEG platform delivers medical-grade data across your cohort. We optimised for comfort and simplicity because the best data comes from patients who keep wearing the device.

ALGORITHM VALIDATION

Benchmarked against
expert manual scoring

AXORA's sleep staging reaches κ 0.79 agreement with expert manual scoring across a broad age range (20–75+ years) and a variety of clinical profiles, including neurodegenerative populations. The result is built on 15+ peer-reviewed studies spanning tens of thousands of hours of EEG data.

Frequently asked questions

How does the signal quality compare to PSG?

AXORA EEG delivers clinical-grade EEG signal quality on part with polysomnography. Our wet electrode setup ensures reliable contact and signal integrity.

How accurate is the sleep staging?

Our automated sleep staging has been validated against expert manually scored hypnograms (AASM criteria) and achieves a Cohen's kappa of 0.79 (95% CI 0.77–0.82). This is consistent with the inter-rater reliability typically observed between human sleep scorers, meaning the algorithm agrees with expert scoring about as closely as expert scorers agree with each other.

Do you offer different sizes?

Yes. AXORA EEG is available in five different sizes to fit a wide range of head circumferences, including a paediatric sizes and models for children. For special populations or custom requirements, we can accommodate additional size specifications on request.

How many electrodes and channels does the device use?

AXORA EEG uses 3 electrodes resulting in 1 active channel for analysis, positioned over the frontal lobe. Frontal EEG captures the clinically relevant sleep endpoints including slow-wave activity, sleep spindles, and full sleep staging. This design is a deliberate choice to maximise wearability and long-term compliance.

Can I use AXORA EEG for high-density EEG research?

No. AXORA EEG is optimised for longitudinal at-home sleep research, not for spatial localisation of brain activity. If your study requires source localisation or high-density cortical mapping, a laboratory setup would be more appropriate. We are happy to discuss whether your endpoints are achievable with our setup.

Does the headband disturb sleep?

No. AXORA EEG is built from soft, lightweight, washable textile specifically designed for all-night wear. Our clinical trials, including studies running 18+ months, show very low dropout rates, indicating high patient acceptance and comfort across extended study durations, including in elderly populations.

How is this different from a consumer sleep tracker or app?

Consumer wearables use accelerometry and heart rate sensors to estimate sleep stages — they do not measure brain activity directly. Independent research has shown that leading consumer devices fail to correctly identify 30–50% of deep sleep and REM epochs compared to PSG. AXORA measures EEG directly from the brain, enabling accurate sleep staging and microstructure endpoints that no wrist-worn device can provide.
