- NCT05373264RecruitingPhase 3
Hydrochlorothiazide to help polycystic kidney disease and quality of life
This Phase 3 study tests whether hydrochlorothiazide can help people with autosomal dominant polycystic kidney disease (ADPKD) and improve quality of life. It also looks at whether it affects kidney health while you stay on your current ADPKD-related treatment.
AntwerpAges 18–80 - NCT03476551Recruiting
Gastric bypass or sleeve check for a water-pill response
This study looks at how well hydrochlorothiazide (a “water pill”) works in the body after gastric bypass or sleeve surgery. It may help doctors better predict dosing and effects after these weight-loss operations.
TrondheimAges 18–70 - NCT03511118Recruiting
Drug safety study for breastfeeding mothers and babies
This study measures how common medicines move through a breastfeeding parent’s milk and checks safety in both the parent and breastfed baby. It may help doctors use these medicines more safely while you continue breastfeeding.
La Jolla, CaliforniaAges Any age - NCT04934228RecruitingPhase 1
Study targeting inflammation in people with obesity and high blood pressure
This Phase 1 study looks at a treatment aimed at reducing “inflammation patterns” that are common in obesity and insulin resistance. If you meet specific health and lab criteria, you may be asked to visit a research lab and provide blood samples to see how the treatment affects your body.
Kansas City, KansasAges 18–79 - NCT05917275RecruitingPhase 4
Testing tests to predict how you’ll respond to blood pressure medicines
This study uses blood and other body measurements to predict how well certain blood pressure medicines will work for you. It may help doctors choose the best treatment sooner, based on your personal “multi-omics” (biomarker) results.
NijmegenAges 18–75 - NCT06111885RecruitingPhase 2
Study of two diuretics to prevent kidney stones
This trial tests two diuretics (indapamide and chlorthalidone) to see if they reduce the risk of forming new calcium kidney stones. It may help people who have had at least two calcium-based kidney stones in the past 10 years.
BernAges 18 years+ - NCT07683585Recruiting
Comparing blood pressure drugs after heart stent placement
This trial compares two different combinations of blood pressure medicines to see which works better for people who have had a heart stent placed. It may help find the best treatment plan for controlling blood pressure after the procedure.
MoscowAges 50–70 - NCT07020104Recruiting
Salt and water in chronic kidney disease
This study looks at how salt builds up in the skin of people with chronic kidney disease. It involves different groups testing either sodium intake, sodium excretion, or water intake to see how these affect blood pressure and kidney function.
Amsterdam-Zuidoost, North HollandAges 18 years+ - NCT07271420RecruitingPhase 4
Blood pressure drug study for dialysis patients
This trial tests whether a common blood pressure medication (thiazide diuretics) helps control high blood pressure in people on peritoneal dialysis. The goal is to see if it can lower blood pressure and improve health.
Hong KongAges 18 years+ - NCT00162474Recruiting
Study of factors that affect warfarin treatment
This study looks at why some people process warfarin (a blood-thinning medicine) differently. It aims to learn what personal or medication factors may affect how well warfarin works, so future dosing can be safer and more accurate.
JerusalemAges 20–50 - NCT07458880Recruiting
Triple blood pressure pill after a brain bleed
This trial tests whether a combination of three blood pressure medicines can better control blood pressure after a brain bleed (intracerebral hemorrhage). It may help prevent another bleed or stroke.

Common questions
- Are there clinical trials studying Hydrochlorothiazide?
- Yes. Clin2 currently lists 11 recruiting studies that include Hydrochlorothiazide, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Hydrochlorothiazide trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Hydrochlorothiazide an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Hydrochlorothiazide or a specific trial is right for you.
