This study looks at “fat inflammation” and diabetes in people who had gastric bypass surgery. It may help doctors understand why some people develop diabetes and how weight-related body changes affect health.
Gothenburg, Västra Götaland CountyAges 18–60 - NCT04326192Recruiting
Spinal cord stimulation to reduce stubborn back and leg pain
This trial tests whether spinal cord stimulation (a treatment where a device sends mild signals to the spinal cord) can improve persistent nerve-type back and leg pain. It is mainly for adults who are already planning to try spinal cord stimulation but have not tried it before.
Portland, OregonAges 21–70 - NCT04334707Recruiting
Study kidney damage in people with long-term diabetes
This study is looking at different kidney health patterns in people with diabetes, especially diabetic kidney disease and people who have not developed kidney damage despite long-term diabetes. It may help researchers understand why kidney problems happen—and what protective factors might prevent them.
Tucson, ArizonaAges 18 years+ - NCT04371042Recruiting
Study of liver disease and genes in people with fatty liver
This study collects information about metabolic and unexplained (cryptogenic) liver disease and looks at “omics” tests, which are lab tests that measure patterns in blood or tissue to learn what drives the disease. It may help researchers better understand fatty liver and related serious complications, like liver scarring and liver cancer.
Roma, Rome/lazio/italyAges 18 years+ - NCT04442334Recruiting
European registry for people with fatty liver
This registry collects health and lifestyle information from adults with suspected or confirmed fatty liver (NAFLD) to help researchers better understand the condition. You may be asked about diet, exercise, alcohol intake, and some liver-related tests.

Using a smart boot to improve diabetic foot offloading
This trial studies whether a special “smart boot” can help people with diabetic foot ulcers rest (offload) the affected foot as they should. Better offloading may improve healing by reducing pressure on the wound.
Downey, CaliforniaAges 18 years+ - NCT04461821Recruiting
Breath test to study disease in children
This study uses a special machine to analyze exhaled breath to learn about different illnesses in children and teens. It may help researchers find breathing “signals” that reflect conditions like breathing problems, nervous system issues, or new/worsening type 1 diabetes.
BaselAges Up to 22 years - NCT04501406RecruitingPhase 2
Low-dose pioglitazone for fatty liver disease in people with type 2 diabetes
This Phase 2 study tests whether low-dose pioglitazone can improve NASH, a type of fatty liver disease, in adults who also have type 2 diabetes. You may be able to join if your diabetes medicines and lab tests meet specific safety and stability requirements.
Gainesville, FloridaAges 21–75 - NCT04505618Recruiting
Eye scan study using special imaging for blood-vessel disease
This study uses a detailed eye scan (optical coherence tomography angiography) to look at how blood vessels in the retina are affected. It may help researchers better understand retinal vascular diseases, though some people will be excluded for safety or image-quality reasons.
Baltimore, MarylandAges 18–99 - NCT04529889Recruiting
Study of gestational diabetes during pregnancy and child outcomes
This study follows pregnant people with gestational diabetes to see how it affects mothers and babies over time. The team may use this information to better understand risks and care for both you and your child.
Guangzhou, GuangdongAges Any age - NCT04530383RecruitingPhase 2
Metformin add-on for adult cystic-fibrosis related diabetes on CF meds
This trial tests whether adding metformin can improve blood-sugar control and related lung cell function in adults who have cystic-fibrosis–related diabetes (CFRD) and are already taking CFTR modulator therapy. It may help if your diabetes is still not well controlled despite those CF medicines.
Kansas City, KansasAges 18 years+ - NCT04547348RecruitingPhase 3
Denosumab for healing an acute Charcot foot in diabetes
This Phase 3 trial tests whether denosumab can improve healing and outcomes for people with an acute Charcot foot caused by diabetes-related nerve problems. You may be able to join if your Charcot foot is recently diagnosed and you meet specific safety and lab requirements.
AalborgAges 18–80 - NCT04585204Recruiting
Tests which sugar drink best detects gestational diabetes
This study compares two different sugar drinks during pregnancy to see which one better identifies gestational diabetes that may need medical treatment. It may help your care team choose the most useful test for you and similar pregnancies.
AnkaraAges 18–45 - NCT04591639Recruiting
DAPA test for diabetes and heart failure using body scans
This study tests how a medication called DAPA (an SGLT2 inhibitor) affects the body in people with heart failure (with or without type 2 diabetes), or in some people with type 2 diabetes only. It may help researchers understand who could benefit most and what changes happen in the heart, using specialized heart imaging.
Edinburgh, ScotlandAges 18 years+ - NCT04607096Recruiting
Intermittent fasting to improve insulin in prediabetes or early type 2
This study tests whether intermittent fasting can improve how your body releases and uses insulin if you have prediabetes or early type 2 diabetes. It may help your blood sugar control without using insulin.
