Recruiting studies in Washington
- NCT07228117Recruiting
Testing a new automated insulin pump for people with diabetes
This study tests a new automated insulin delivery system (a pump that helps manage blood sugar) in children and adults with diabetes. It aims to see if the system is safe and easy to use in daily life.
Renton, WashingtonAges 7–85 - NCT07088068RecruitingPhase 3
Teplizumab for newly diagnosed type 1 diabetes
This study tests whether teplizumab can help keep the body making insulin in people recently diagnosed with type 1 diabetes. It is for children and young adults aged 1 to 25, and compares the drug against a placebo.

Seattle, WashingtonAges 12–25 - NCT05819138RecruitingPhase 3
Semaglutide for heart outcomes in adults with type 1 diabetes

You may qualify if you have had type 1 diabetes for at least 8 years, have moderate kidney damage, and are on standard treatments.
Spokane, WashingtonAges 18–75 - NCT06384911Recruiting

Seattle, WashingtonAges 12 years+ - NCT07606066Recruiting
Finding Type 2 Diabetes Patients for Future Research Studies
This is a screening study to identify and understand people with type 2 diabetes whose blood sugar isn't well controlled, so they can potentially join future diabetes research trials. You won't receive a new treatment in this study—it's about getting to know your health history and seeing if you might be a good fit for upcoming studies.
Renton, WashingtonAges 18 years+ - NCT06964087RecruitingPhase 2
Testing OPT101 for type 1 diabetes
This trial tests an investigational drug called OPT101 in people with type 1 diabetes. It aims to see how the drug works in the body and whether it can help preserve insulin production, especially in those diagnosed recently or within the last 20 years.
Renton, WashingtonAges 18–50 - NCT07061574RecruitingPhase 1/Phase 2
Low-dose ATG with Adalimumab or Verapamil for new type 1 diabetes
This study tests if giving a low dose of an immune-suppressing drug (ATG) followed by either adalimumab or verapamil can help preserve insulin production in people recently diagnosed with type 1 diabetes. You may qualify if you are 9 to 20 years old, have had type 1 diabetes for less than 6 months, and have some natural insulin left.
Seattle, WashingtonAges 9–20 - NCT07142252RecruitingPhase 2
New drug for recently diagnosed type 1 diabetes
This trial tests a new medicine (rezpegaldesleukin) to see if it can help preserve the body's ability to make some insulin in people recently diagnosed with type 1 diabetes. It's for children and adults diagnosed within the past 100 days.
Seattle, WashingtonAges 8–45 - NCT07187531RecruitingPhase 2
Testing a new drug to slow type 1 diabetes progression

Seattle, WashingtonAges 5–40 - NCT07292558Recruiting
Support program for young adults with type 1 diabetes
This study looks at whether a special program designed for emerging adults (ages 16-19) with type 1 diabetes can help improve blood sugar control and overall health. It takes place in the Seattle area and involves both the program and usual diabetes care.
Seattle, WashingtonAges 16–19 - NCT02734277Recruiting
Extending a past Type 1 diabetes immune study
This study is for people who already took part in an earlier immune-tolerance program for Type 1 diabetes. It tests whether continuing follow-up and assessments can be done safely and may help learn more about long-term immune effects of treatment.
Seattle, WashingtonAges 8–35 - NCT03369821Recruiting
Study of immune changes in very early childhood type 1 diabetes
This study looks at immune system cells and gene activity in infants and young children to understand what causes type 1 diabetes to start so early. It may help researchers find earlier warning signs and better ways to support families right at diagnosis.
Seattle, WashingtonAges Up to 70 years - NCT07076199RecruitingPhase 3
Weekly vs daily insulin for type 1 diabetes
This study tests a new once-weekly insulin (icodec) against a standard daily insulin (glargine), both taken with mealtime insulin. It aims to see which works better to control blood sugar in adults with type 1 diabetes.
Renton, WashingtonAges 18 years+ - NCT07518004Recruiting
ROME GS System Study for diabetes glucose monitoring
This study tests the ROME GS System, a glucose monitoring device that measures blood sugar levels. The system includes a sensor placed under the skin and a transmitter worn on the body. If you have diabetes and want to help evaluate a new way to track your blood sugar, this trial may be for you.
Renton, WashingtonAges 18 years+ - NCT04677699Enrolling by invitation

Seattle, WashingtonAges 1 day–7 years - NCT05780905RecruitingPhase 4
Semaglutide study for brain blood flow in type 2 diabetes
This trial tests whether semaglutide changes blood flow in the brain and the brain’s “barrier” (how well the brain is protected) in people with type 2 diabetes. It may help researchers understand brain-related effects of diabetes treatment using scans and blood tests.

What taking part in a type 1 diabetes study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
