This trial tests if a remote exercise program can help control blood sugar and improve fitness in people with type 2 diabetes. It is for those who are newly diagnosed or have had diabetes for up to 5 years and are not taking diabetes medication.
Chengdu, SichuanAges 18–69 - NCT06118931Recruiting
Time-Restricted Eating for Blood Sugar Control
This study tests whether eating only during a specific daily window helps control blood sugar in people with or at risk for type 2 diabetes. You'll follow a set eating schedule and use a phone app to track your meals.
Toronto, OntarioAges 40 years+ - NCT06813339RecruitingEarly Phase 1
Testing a new drug in healthy people and those with heart condition
This trial tests a new medicine called UDP-003 in two groups: healthy volunteers and people who had a heart event (acute coronary syndrome) at least a year ago. The goal is to see if the drug is safe and how the body handles it, which could lead to better treatments for heart disease.
Adelaide, South AustraliaAges 18–79 - NCT07675473RecruitingPhase 4
Pain relief before lung nodule localization
This trial tests giving a pain medicine (parecoxib) before a CT-guided lung nodule procedure to see if it reduces pain during the treatment. It's for people with non-small cell lung cancer who need a wire placed in their lung before surgery.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07675993Recruiting
Sleep and anesthesia in non-heart surgery
This study looks at how sleep problems before surgery affect the amount of anesthesia needed and how well you recover after non-cardiac surgery. The goal is to help doctors personalize care for better recovery.
Yinchuan, NingxiaAges 18–65 - NCT07247123Recruiting
Skin cancer self-check education program
This trial tests a new educational program to help people learn how to check their own skin for signs of skin cancer. It aims to make early detection easier, and you can join regardless of whether you have had skin cancer before.
Singapore, SingaporeAges 16 years+ - NCT07675603Recruiting
Low-carb diet and cholesterol study
This study looks at how a low-carb, high-fat ketogenic diet affects cholesterol levels in healthy adults. It may help you understand how your body responds to this type of diet.
Bath, Bath and North East SomersetAges 18 years+ - NCT07037888RecruitingPhase 4
Ketorolac for pain after hip arthroscopy

Common questions
- Are there clinical trials for control?
- Yes. Clin2 currently lists 3,034 recruiting control 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 control 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 control 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.
