Recruiting studies
- NCT01477957Recruiting
Bariatric surgery and changes in insulin and body energy use
This study tests whether weight-loss surgery improves how your body uses insulin and energy. It compares insulin sensitivity and related measurements before and after surgery to understand who benefits.
Düsseldorf, North Rhine-WestphaliaAges 20–70 - NCT01852448Recruiting
Study genes affecting insulin in people with cystic fibrosis
This study looks at how genes may affect insulin and “incretin” hormones in people with cystic fibrosis. It may help researchers understand why some people develop blood-sugar problems and how to predict or prevent them.
Philadelphia, PennsylvaniaAges 2 years+ - NCT06597149Recruiting
Ear stimulation for insulin levels in healthy volunteers
This study tests whether a gentle electrical stimulation in the ear can change insulin levels in the blood. It is for healthy adults who are willing to have small sensors and a blood draw.
Indianapolis, IndianaAges 18–70 - NCT00903110Recruiting
Long-term safety registry for Increlex in children
This study is a registry that follows children and teens with severe IGF-1 deficiency who use Increlex (or specific GH gene deletion situations) to better track long-term safety and effectiveness. You would likely join if your child is already starting or planning Increlex and is not in other growth-related drug trials.
Orange, CaliforniaAges 2–18 - NCT00992901RecruitingEarly Phase 1
Testing hormones and nerve signals after gastric bypass
This early-phase study looks at how the body’s hormone signals and nerve control affect insulin release after gastric bypass surgery. It may help researchers understand what drives low blood sugar and how to better monitor or treat it.
San Antonio, TexasAges 18–65 - NCT01224886Recruiting
Study of age-related insulin resistance and exercise
This study looks at how age affects the way your body uses insulin (a hormone that helps move sugar into cells), and how lifestyle or exercise may change that. It may help you understand insulin resistance and whether changes in activity could improve blood sugar control.
BernAges 60–80 - NCT07635576Recruiting
How Stomach Stimulation Affects Insulin Levels
This study looks at how a surgically implanted device that stimulates the stomach (called a GES device) affects your body's insulin levels. Researchers will collect blood samples over several hours to understand if and how the device influences insulin production.
Indianapolis, IndianaAges 18 years+ - NCT01143480Recruiting
Testing how the body responds to endotoxin
This study checks how your immune system (your body’s defense system) reacts to a controlled substance that triggers inflammation. It may help researchers understand why some people have stronger or weaker inflammatory responses.
Research Triangle Park, North CarolinaAges 18–100 - NCT06646107Recruiting
Mediterranean diet and insulin pump in type 1 diabetes
This trial tests whether following a Mediterranean diet can improve blood sugar control and insulin use in people with type 1 diabetes who are starting a new insulin pump (MiniMed 780G). It compares how diet affects glucose levels and insulin needs.
ChaïdáriAges 12–80 - NCT06193668Recruiting
Overfeeding and fat tissue stimulation study
This trial looks at how overfeeding affects fat tissue in healthy, inactive young adults. You may help researchers understand weight gain and metabolism.
Düsseldorf, North Rhine-WestphaliaAges 18–40 - NCT05831709Recruiting
Hormone therapy and supervised exercise in menopausal women
This study looks at how hormone replacement therapy and a supervised exercise program may change body composition, heart health risk, and insulin sensitivity in postmenopausal women. It may help participants understand which combination works best for metabolic and cardiovascular health after menopause.
GhentAges 45–65 - NCT05258292Recruiting
Track blood sugar changes with your period in type 1 diabetes
This study monitors how your blood sugar (glucose) changes across your menstrual cycle using a continuous glucose monitor. It may help researchers understand patterns that could improve diabetes care around monthly hormonal changes.
Montreal, QuebecAges 18–50 - NCT04375657RecruitingPhase 2
Study to restore thymus function and improve insulin control
This Phase 2 study tests a treatment aimed at improving immune system function and reducing insulin problems over 12 months. You may be able to join if you’re between 40 and 80 and don’t have certain diabetes, hormonal, heart, or immune conditions.
Torrance, CaliforniaAges 40–80 - NCT03956602Recruiting
Snack choices and their effect on blood sugar
This trial studies how different snack types affect quick changes in blood sugar and insulin. It may help researchers understand which snacks cause smaller or larger spikes after eating.
San Diego, CaliforniaAges 18–55 - NCT03883412RecruitingPhase 4
Exercise and liraglutide for type 2 diabetes
This study tests if combining exercise with a drug called liraglutide improves blood vessel health and insulin sensitivity in people with type 2 diabetes. It looks at whether these treatments work better together or alone.
Charlottesville, VirginiaAges 21–60 - NCT07801001Enrolling by invitation
Zinc supplements for women with polycystic ovary syndrome
This study tests whether taking zinc supplements can improve insulin resistance and reduce symptoms in women with polycystic ovary syndrome (PCOS). If you have PCOS and are not pregnant, you may be able to join.
DhakaAges 18–45 - NCT07057245Recruiting
Protein supplement and brain function in older adults
This study tests whether taking a daily protein supplement can improve how your brain works. It is for healthy older adults (ages 60–75) who are overweight but do not have diabetes or take certain medications.
Maastricht, LimburgAges 60–75 - NCT07587905Recruiting
How calamansi fruit affects blood sugar in healthy adults
This study tests whether drinking or eating calamansi (a small citrus fruit) can help keep blood sugar levels healthy. Researchers will measure how it affects glucose and insulin in people without diabetes.
Mueang, Burapha UniversityAges 18–30 - NCT07242664RecruitingPhase 1
Testing a new long-acting insulin in type 1 diabetes
This study compares a new investigational long-acting insulin (GZR33) to an approved one (insulin degludec) in people with type 1 diabetes. You would receive both insulins during an inpatient 'clamp' procedure to see how well they work, which may help find a more affordable or convenient option for daily blood sugar control.
NeussAges 18–64 - NCT07177781Recruiting
Blueberries and brain function in older adults
This study tests whether eating wild blueberries every day for several weeks can improve brain function in people ages 60 to 75 who are overweight or obese. You'll eat blueberry powder or a placebo and have memory and thinking tests before and after.
Maastricht, LimburgAges 60–75 - NCT07103083Recruiting
How your body responds to fruit juice

Common questions
- Are there clinical trials for insulin?
- Yes. Clin2 currently lists 344 recruiting insulin 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 insulin 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 insulin 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.
