Investigators still do not fully understand how diabetes develops and how the disease worsens. Insulin is a hormone that helps the body use sugar as a fuel and control blood-sugar levels. People with diabetes have problems making insulin. This is because their insulin-producing beta cells -in the pancreas-are damaged or destroyed. A biomarker is a biological molecule (such as DNA, RNA (the genetic material of cells) or protein) that is a sign of a normal or abnormal process, or of a condition or disease. A biomarker can be measured and found in blood and/or other body fluids (such as saliva and urine). Understanding the biology of beta cells could help find diabetes-related biomarkers. The discoveries from this research could help with early diagnosis of diabetes and lead to the creation of therapies for treating diabetes.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Participants from the clinic environment/ local providers/ diabetes events, relatives/ friends of participants, employees, and normal healthy participants from the community', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Documented informed consent/ assent from the subject\n* ONE of the following:\n\n * Type 1 diabetes patients (including pediatric patients) -OR-\n * Adult type 2 diabetes patients -OR-\n * Volunteers who are islet auto-antibody positive (i.e. insulin, GAA, IA-2, IAA and ZnT8 antibodies) with HbA1c ≤ 5.6% (including pediatric patients)-OR-\n * Adult participants with clinical diagnosis of high blood sugar (i.e. HbA1c of 5.7% to 6.4%)-OR-\n * Adult control subjects with HbA1cc ≤ 5.6%\n* Weight ≥ 30 kg\n* Willingness to: Provide blood sample(s) and if applicable: permit medical record/ clinical laboratory result review\n\nExclusion Criteria:\n\n* Control subjects must not have any chronic conditions or have undergone cellular, tissue or organ transplant\n* Sickle cell disease or anemia (exception: anemia that is corrected with treatment and source documents confirm corrected blood parameters current within 6 months of blood draw)\n* Active infection\n* Active malignancy (i.e., currently undergoing treatment)\n* Immunomodulatory therapy within 1 year of planned blood draw (may include immune checkpoint inhibitors, thalidomide, lenalidomide, pomalidomide, imiquimod, Bacillus Calmette-Guérin, and cytokines/ growth factors (e.g. interferons, interleukins)\n* Type 1 diabetes only: polyclonal regulatory T cell and/or dendritic cell therapy\n* Bleeding disorder\n* Women of childbearing potential: Pregnant/ nursing (Note: Eligibility may be deferred per blood donation timelines for pregnancy/nursing)\n* Diabetic patients only: Any clinical condition that might be adversely affected by the removal of up to 100 mL of blood\n* An employee who is under the direct/ indirect supervision of the PI/ a co-investigator/ the study manager\n* A direct study team member'}, 'identificationModule': {'nctId': 'NCT05505669', 'briefTitle': 'Circulating Biomarkers in the Development of Type 1 Diabetes', 'organization': {'class': 'OTHER', 'fullName': 'City of Hope Medical Center'}, 'officialTitle': 'Circulating Biomarkers of Beta Cell Loss/Dysfunction in Diabetes', 'orgStudyIdInfo': {'id': '20477'}, 'secondaryIdInfos': [{'id': 'R01DK125856', 'link': 'https://reporter.nih.gov/quickSearch/R01DK125856', 'type': 'NIH'}]}, 'armsInterventionsModule': {'armGroups': [{'label': 'Adults with type 1 diabetes', 'description': 'Adults with type 1 diabetes', 'interventionNames': ['Other: One-time blood (up to 100 ml) will be drawn and the amount of blood drawn is based on weight.
