How preoperative fasting affects heart function
This study looks at how the heart's right chamber works in patients who have fasted before surgery. Researchers use an ultrasound test to measure a specific heart function and want to see if not drinking fluids or taking sedatives before surgery changes it.
Aydin, ZaferAges 18–75 - NCT07009288Recruiting
Time-restricted eating for childhood cancer survivors

Stomach contents in tirzepatide users and fasting volunteers
This study uses an ultrasound to look at the stomach contents of people who are taking tirzepatide compared to those who are not. It will help doctors understand how this medication affects stomach emptying during fasting.

Compare suture types to reduce skin color changes after surgery
This study looks at whether different types of stitches (sutures) can lower the chance of pigment changes—skin color looking lighter or darker—after dermatology surgery. It may help patients who want to reduce the risk of visible skin color changes as their wound heals.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT06454773RecruitingPhase 3
Can hemp and black pepper help lower blood sugar in prediabetes?
This study tests if taking extracts from hemp hulls and black pepper can help lower fasting blood sugar levels in people with prediabetes. It compares the effects of these natural compounds against a placebo (a pill with no active ingredients).
DelhiAges 25–60 - NCT06511375Recruiting
Sprint vs. power training for cricket fast bowlers
This trial compares two types of training—sprint training and power training—to see which one helps fast bowlers improve their performance. If you are a healthy fast bowler between 18 and 30 years old with at least two years of experience, this study may be for you.
Zafarwal, Punjab ProvinceAges 18–30 - NCT07204795Recruiting

This study tests if drinking a sugary drink before a planned C-section improves recovery. It may help women feel better after surgery.
ErzurumAges 18 years+ - NCT07251803Recruiting
GLP-1 medication stomach emptying study
This study uses an ultrasound to look at how full your stomach is after taking GLP-1 medications for diabetes or weight loss. It will help doctors understand if current fasting guidelines are safe before surgery or a colonoscopy.

Comparing Two Versions of a Hair-Loss Medication
This study tests whether two versions of the same medication (AJU-G721 and G721R)—used to treat hair loss and urinary symptoms—work the same way in the body. Researchers will measure how much medication gets absorbed and how long it stays in your system.
SeoulAges 19–54 - NCT07628270Recruiting
Heart Surgery Outcomes Study Using CT Scans and Blood Tests
This study follows patients who had heart bypass surgery guided by special CT scans and blood flow measurements. Researchers want to understand how well the surgery works and study a blood protein called Lp(a) that may affect heart health.
Milan, MIAges 18 years+ - NCT07260318Enrolling by invitation
How fast bowling affects bone health
This study looks at how cricket fast bowling affects your bone health and the signals your body sends to build or break down bone. If you're a healthy young male fast bowler, this trial will help understand the immediate impact of bowling on your bones.

- How do I know if I qualify for a fasting 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 fasting 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.
