An observational study in Rheumatic Diseases, Adult Onset Still Disease and Ankylosing Spondylitis, sponsored by Yale University. Recruiting at 1 site in United States. Open to participants aged 18 Years to 99 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-02-13.
Sponsored by Yale University · Observational
To facilitate clinical, basic science, and translational research projects involving the study of rheumatic diseases.
A rheumatology biorepository will be created to permit comparative analyses between the rheumatic diseases in order to increase the understanding of disease pathogenesis. Patients seen at Yale clinics diagnosed with rheumatic diseases are invited to participate in this study. These rheumatic diseases include, but are not limited to: adult onset Still's disease, ankylosing spondylitis, psoriatic arthritis, reactive arthritis, antiphospholipid syndrome, systemic lupus erythematosus, Behcet's disease, dermatomyositis, polymyositis, giant cell arteritis and other vasculitides, Lyme's disease, mixed connective tissue disease, polymyalgia rheumatica, rheumatoid arthritis, sarcoidosis, systemic sclerosis (scleroderma), Sjogren's syndrome, and undifferentiated connective tissue disease.
264 studies on the registry are indexed under Rheumatic Diseases; 60 are open to participants now.
This study's planned enrollment of 5,000 is above the median of 225 across 90 observational studies indexed under Rheumatic Diseases.
Browse Rheumatic Diseases studies →Yale University is the lead sponsor of 1,770 studies on the registry; 294 are open to participants now.
Of its 221 completed or terminated interventional studies of FDA-regulated products, 129 (58%) have results posted.
Counted across the registry records on this site, refreshed daily.
The biorepository will consist of both new and established patients with a rheumatic autoimmune disease diagnosis who visit a Yale Rheumatology medical facility and agree to participate in this study. The biorepository will also consist of healthy volunteers who agree to participate in this study.

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.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
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.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Started Aug 2020 (actual). Primary completion is estimated for Jun 2030, 117 months after the start.
Of 36 observational studies under Rheumatic Diseases, half reached primary completion within 55 months of starting (the median), counting those still running; a quarter within 14. This study's planned 117 months is above that.
