Recruiting studies
- NCT06575790Recruiting
Comparing simplified meal boluses to carb counting for teens with automated insulin pumps
This study tests if a simpler way of calculating meal insulin works as well as counting carbohydrates for teens using hybrid closed loop (automated insulin) systems. If you're a teen with type 1 diabetes and use an automated pump, this trial could help find an easier mealtime routine.
Aurora, ColoradoAges 14–26 - NCT06624046Recruiting
Sleep and glucose study for type 1 diabetes
This study looks at how sleep affects blood sugar and heart health in people with type 1 diabetes. If you have irregular sleep and want to improve it, researchers will test a wearable device and sleep coaching.
Chicago, IllinoisAges 18–50 - NCT06665815Recruiting
Screening close family for type 1 diabetes risk
This study screens close family members of people with type 1 diabetes for early signs of the condition. A simple blood test looks for special markers (autoantibodies) that can show if the immune system is starting to attack the pancreas. Finding these markers early may help doctors prevent or delay the onset of diabetes.
Petah TikvaAges 2–45 - NCT06676657Recruiting
Closed loop with context-aware insulin delivery for type 1 diabetes
This study tests a smart insulin pump system that adjusts automatically during exercise. It aims to make managing blood sugar easier and safer.
Portland, OregonAges 18–100 - NCT06686329Recruiting
Exercise for blood sugar correction after insulin timing error
This trial looks at whether physical activity can help treat or prevent high blood sugar caused by taking a rapid-acting insulin dose at the wrong time. If you are a young adult with type 1 diabetes and use a Dexcom G7 continuous glucose monitor, this study may help you learn how to use exercise as a tool for managing unexpected blood sugar spikes.
Montreal, QuebecAges 18–24 - NCT06687434Recruiting
Carb counting vs. simple meal-size estimation for type 1 diabetes
This study compares two ways of estimating meal size for people with type 1 diabetes who use automated insulin delivery systems. One method is detailed carb counting, the other is a simpler, qualitative estimate of meal size. The goal is to see which approach works better for managing blood sugar.
Petah TikvaAges 6–18 - NCT06708780RecruitingPhase 1
Treg cell therapy for type 1 diabetes
This trial tests whether giving your own regulatory T cells (a type of immune cell) back to you can help slow or stop the immune attack on your pancreas in type 1 diabetes. It is for people aged 8 to 65 who still make some insulin.
Nanjing, JiangsuAges 8–65 - NCT06770621Recruiting
Glucagon response study in new type 1 diabetes
This study looks at how the body makes glucagon (a hormone that raises blood sugar) in children and teens with new type 1 diabetes. It aims to understand why some people may have dangerous low blood sugars, so doctors can better prevent them in the future.
Brussels, Woluwe-saint-lambertAges 2–30 - NCT06829251Recruiting
Ear massage for stress and sleep in parents of children with diabetes
This study tests if a simple ear massage you can do at home helps reduce stress, anxiety, and improve sleep for parents of children with type 1 diabetes. You would learn the massage during online sessions and do it for a few weeks.
MersinAges 21–60 - NCT06891898Recruiting
The iLet Experience Study
This study is testing the iLet Bionic Pancreas System in people with type 1 diabetes. It looks at how well the system works in your daily life and asks you to share your glucose data and answer surveys.
Irvine, CaliforniaAges 6 years+ - NCT06918444Recruiting
Can a mobile app help you live healthier?
This trial tests a smartphone app called WARIFA that gives personalized advice to help prevent chronic diseases and manage diabetes. It is for healthy people or those with one chronic condition, and also for people with type 1 diabetes who use insulin and a continuous glucose monitor.
Las Palmas de Gran Canaria, Las PalmasAges 18 years+ - NCT07145671Recruiting
Helping teens with chronic conditions move to adult care
This study tests a transition program to help young people move from pediatric to adult medical care. It looks at whether extra support makes this change easier for teens with type 1 diabetes, asthma, or obesity.
GhentAges 16–21 - NCT07179471Recruiting
Fake Carbs Practice with MiniMed 780G for Kids with T1D
This trial tests whether using a practice 'fake carbs' method helps children and teens with type 1 diabetes manage their glucose levels better with the MiniMed 780G insulin pump in auto mode.
Athens, AtticaAges 7–19 - NCT07212530Recruiting
EmoTIChealth: A game to boost teen health
This trial tests a serious video game designed to help teenagers learn skills for better health. It's for 12- to 16-year-olds who speak Spanish and have internet access.
Valencia, ValenciaAges 12–16 - NCT07296276Recruiting
Testing the CareSens Air 3 glucose monitor in type 1 diabetes
This study tests how accurate a new continuous glucose monitor (CGM) called CareSens Air 3 is for adults with type 1 diabetes. You would wear the sensor on your skin to track blood sugar levels, and it may help you manage your diabetes more easily.
Escondido, CaliforniaAges 18–65 - NCT07341243Recruiting
Exercise in heat and blood sugar in type 1 diabetes
This study tests how exercising in hot conditions affects blood sugar levels in people with type 1 diabetes. It aims to help you understand how to manage your glucose when it's warm.

Long-Term Effects of Teplizumab in Real-World Care
This study follows people who have already received teplizumab (a treatment to delay type 1 diabetes) to see how they do over time. It aims to understand the long-term effects in routine care.

Long-term follow-up after islet transplant graft failure
This study follows people over the long term after their islet transplant fully stops working. It aims to learn what happens after complete graft loss and monitor health outcomes over time.
Miami, FloridaAges 18–75 - NCT01999374Recruiting
Long-term follow-up for people with transplanted islet cells
This study checks how well transplanted islet cells are working over time and monitors long-term safety. If you previously received an islet transplant and are still using medicine to prevent rejection, you may be followed again.
Miami, FloridaAges 18–65 - NCT01999361Recruiting
Prevent new immune reaction after islet transplant failure
This study looks at ways to prevent the body from developing a new harmful immune reaction after an islet transplant no longer works. It may help people who have already lost a transplanted islet graft from getting harder-to-treat immune responses later.
Miami, FloridaAges 18–70 - NCT05498116RecruitingPhase 4
Montelukast to improve kidney and blood vessel function in type 1 diabetes
This trial tests whether montelukast, a medicine commonly used for allergies, can improve kidney health and blood vessel function in adults with long-term type 1 diabetes. You may join a treatment group and have kidney and circulation measurements taken over the study period.

StrasbourgAges 18 years+ - NCT07507708Recruiting
Smart insulin system with behavior support for type 1 diabetes
This study tests a smart insulin pump and continuous glucose monitor system that adjusts insulin automatically and uses behavior support to improve blood sugar control. It's for people with type 1 diabetes who have used an approved automated insulin delivery system recently and are willing to use study devices.

Common questions
- Are there clinical trials for type 1 diabetes?
- Yes. Clin2 currently lists 875 recruiting type 1 diabetes studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a type 1 diabetes trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a type 1 diabetes trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
