Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

The disease, disorder, syndrome, illness, or injury that is being studied.
The investigators are interested in learning about the immune cells in the blood that contribute to disease in patients with rheumatoid arthritis (RA). They have developed a method for identifying a specific type of immune cells that can react against normal tissues in the body. In this study, the investigators will enroll RA patients from the University of Minnesota clinics, collect blood samples from enrolled patients, and process the blood samples to isolate DNA, RNA, serum, and blood cells. They will use the serum to detect whether specific autoantibodies (Anti-cyclic Citrullinated Peptide, or anti-CCP) are present. In cases where anti-CCP antibodies are detected, the investigators may quantify the numbers of immune cells present that contain receptors with the same anti-CCP specificity. They may also test whether the numbers of immune cells with these receptors correlate with measures of disease activity in RA patients.
