An observational study in Patients Undergoing Routine Health Care, Heart Diseases and Inflammatory Bowel Diseases, sponsored by University of Chicago. Recruiting at 1 site in United States. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-03-04.
Sponsored by University of Chicago · Observational
The purpose of this study is to collect DNA samples from patients undergoing routine care at the University of Chicago. These samples will be tested for differences in genes that may suggest greater risk of side effects or chance of increased benefit from certain medications. The results will be made available to the patient's treating physician and the researchers will track whether or not this information is used in routine health care.
2,135 studies on the registry are indexed under Heart Diseases; 252 are open to participants now.
This study's planned enrollment of 1,200 is above the median of 350 across 592 observational studies indexed under Heart Diseases.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Patients with certain diseases, or likely to receive or be receiving certain drugs, will be targeted particularly for enrollment in order to enrich the study for patients likely to have pharmacogenetically relevant interactions, including, but not limited to:
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.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
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.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
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 Jan 2011 (actual). Primary completion is estimated for Nov 2027, 202 months after the start.
Of 184 non-industry observational studies under Heart Diseases, half reached primary completion within 49 months of starting (the median), counting those still running; a quarter within 22 and three quarters within 118. This study's planned 202 months is above that.
Counting every sponsor, half of 238 studies reached it within 45 months; a quarter within 18 and three quarters within 95.
How these figures are worked out, and which studies are left out of them.
