AI aims to end Skin-Tone bias in dermatology

NCT ID NCT07765303

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study is testing whether artificial intelligence can accurately classify skin pigment, sun sensitivity (phototype), and sun damage from standard photos of the arm. Researchers will enroll 1,500 adults from diverse backgrounds, combining objective color measurements, expert assessments, and questionnaires to train the AI. The goal is to create fairer, more reliable tools for skin cancer risk assessment and dermatology diagnosis across all skin tones.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Artificial intelligence algorithms for skin image analysis
What this could lead to
If successful, this could lead to AI tools that more accurately assess skin cancer risk and tailor sun protection advice across all skin tones.
What could go wrong
The AI may not achieve the target accuracy in all populations, and the study is observational, so it won't directly test a treatment. Privacy risks are minimal but present.

Study facts

What this study's own registry entry says, in plain language.

Participants

About 1,500 people

The number the study aims to enrol. It can still change while the study runs.

Started

Apr 2025

Expected to finish

Dec 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Adults aged 18 years and older will be recruited from dermatology clinics, hospital waiting areas, universities, and other public settings at participating study sites (at present 11 but more are being recruited). The study aims to include individuals representing a broad range of skin pigmentation levels, skin phototypes, and degrees of photodamage. Participants will undergo non-invasive skin imaging, skin characteristic assessments, and questionnaire-based data collection to support the development and validation of artificial intelligence algorithms for classification of skin pigmentation, phototype, and photodamage.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Inclusion Criteria: * Aged 18 years or older * Able and willing to provide informed consent (oral or written, according to local regulations) * Willing to complete the study questionnaire * Willing to undergo non-invasive skin imaging and skin characteristic assessments of predefined sites on the upper arm and forearm Exclusion Criteria: * Younger than 18 years of age * Unable to provide informed consent * Unable to complete study procedures * Tattoos, prominent scars, wounds, skin lesions, dressings, or other identifiable features at the predefined imaging sites that may interfere with image acquisition, assessment quality, or participant anonymity
