An observational study in Vitiligo and Healthy, sponsored by Northwestern University. Recruiting at 1 site in United States. Open to participants aged 18 Years to 89 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-06-09.
Sponsored by Northwestern University · Observational
Investigators plan to perform a pilot study that aims to characterize the microbiome of human vitiligo patients with both active and stable disease and compare this to the microbiome of age and sex matched controls. The investigators aim to answer the question whether the gut and skin microbiome of patients with vitiligo differs from the general population.
343 studies on the registry are indexed under Vitiligo; 96 are open to participants now.
This study's planned enrollment of 100 is below the median of 114 across 67 observational studies indexed under Vitiligo.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Started May 2019 (actual). Primary completion is estimated for Dec 2026, 91 months after the start.
Of 25 observational studies under Vitiligo, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 10. This study's planned 91 months is above that.
