Recruiting studies
- NCT07410780Recruiting
Pain after root canal with two different sealers
This trial compares two types of root canal filling materials—bioceramic and calcium hydroxide—to see which one causes less pain after the procedure. If you have a tooth with a live but inflamed nerve, you may be able to join.

Vitamin K, D-chiro inositol and α-lactalbumin for bone health
This trial tests a combination of vitamin K, D-chiro inositol, and α-lactalbumin to help maintain bone strength in women with breast cancer who are on hormone therapy and have low vitamin D. It aims to see if these supplements improve bone health while you take a standard bone medication (alendronate).
Latina, ItalyAges 35–70 - NCT07241013Recruiting
Amniotic membrane dressing for C-section wound healing
This trial tests a special dressing made from amniotic membrane (the thin sac that surrounds a baby in the womb) and calcium alginate, placed on the C-section incision to help it heal better.

Ann Arbor, MichiganAges 18 years+ - NCT06853340Recruiting
Calcium and blood vessel hardening in sepsis shock
This study looks at how calcium buildup in blood vessels and a specific receptor on immune cells might affect recovery from septic shock. It aims to understand if these factors impact how well patients respond to treatment.
AmiensAges 18 years+ - NCT07187544Recruiting
Carbetocin and calcium for uterine tone during c-section
This study tests if giving carbetocin with calcium helps the uterus contract better after a planned c-section. It's for women at 37+ weeks without high risk for poor uterine tone.
Toronto, OntarioAges 18–45 - NCT07007338Recruiting
Calcium bone balance in children on dialysis starting cinacalcet

BordeauxAges 3–17 - NCT06987084Enrolling by invitationEarly Phase 1
Bryophyllum Tea for Kidney Stone Prevention
This study tests whether a special tea made from the Bryophyllum pinnatum plant can help people who get calcium kidney stones. If you've had a stone or high calcium in your urine, this trial may offer a natural option to try.
Montreal, QuebecAges 18–70 - NCT06930391Recruiting
How calcium affects a drug that helps the uterus contract
This trial tests if adding calcium changes how well a drug called carbetocin works to make the uterus contract after a planned C-section. It may help doctors prevent heavy bleeding after delivery.
Toronto, OntarioAges 18–40 - NCT06826391Enrolling by invitation
Can a filler injection treat gum recession and tooth sensitivity?
This study tests a special injectable filler (calcium hydroxylapatite) to see if it can help grow back gums that have receded and reduce tooth sensitivity. It is for people with mild to moderate gum recession who are in good health.
South Euclid, OhioAges 20–70 - NCT06021080Recruiting
Comparing kidney dialysis patterns on calcium levels with citrate blood thinner
This study compares different patterns of continuous kidney dialysis (called CRRT) to see how they affect calcium levels in the blood when using a citrate-based blood thinner. It may help find the safest way to manage calcium during treatment.
Fuzhou, FujianAges 18–100 - NCT06643468Enrolling by invitation
ALB-PRF with bone grafts for immediate dental implants
This trial tests whether using a special protein-rich blood product (ALB-PRF) with two different types of putty-like bone grafts helps improve the success of dental implants placed right after a tooth is removed in the front upper jaw. It may help people who need a tooth replaced in the 'smile zone' and have good oral health.
Al MansurahAges 20–60 - NCT06580782RecruitingPhase 4
Calcium tablets to help labor contractions
This study tests if taking calcium carbonate (like a Tums tablet) can help make contractions stronger during labor. It is for women having their first baby who need oxytocin to start or strengthen labor.
New York, New YorkAges 18 years+ - NCT06235749Recruiting
Calcium gluconate to reduce bleeding during planned C-section
This study tests whether giving calcium gluconate during a planned cesarean can reduce blood loss. It may be an option for women who are at least 35 weeks pregnant and have no conditions that affect calcium or heart rhythm.
BeershebaAges 18 years+ - NCT06003348RecruitingPhase 4
Can a supplement help prevent calcium phosphate kidney stones?
This study tests a supplement called hydroxycitrate to see if it can help people who form calcium phosphate kidney stones. It may offer a new way to prevent stones from forming.
Dallas, TexasAges 21–99 - NCT05958342RecruitingPhase 2
Calcium and vasopressin for bleeding shock after major injury
This trial tests whether giving calcium and vasopressin early can improve outcomes in people with major injury who are at risk for life-threatening bleeding shock. It mainly includes patients who need rapid blood transfusion and likely major surgery to stop bleeding.
Chandler, ArizonaAges 18–90 - NCT04602754RecruitingPhase 3
Oral treatment test for type 2 diabetes and bad cholesterol
This Phase 3 study tests whether Berlim 25/20 can improve blood sugar control and cholesterol (LDL) in adults with type 2 diabetes who haven’t met targets despite prior lifestyle guidance and treatment. It also looks at safety, including effects on the heart and medication-related side effects.
Campinas, São PauloAges 18–85 - NCT03630991RecruitingPhase 1
Calcium chelator medicine for AML or MDS during chemotherapy
This Phase 1 study tests whether edetate calcium disodium (also called succimer) can be safely given to people with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) while they are on chemotherapy. The goal is to learn the safest dose and whether it has signs of helping the blood cancer respond to treatment.
Houston, TexasAges 1 year+ - NCT02791152Recruiting
Exercise and blood pressure monitoring in healthy adults
This study looks at how physical activity and regular blood pressure checks relate to heart health signals on imaging. It’s meant for people without major heart, stroke, diabetes, or serious chronic illnesses to understand early cardiovascular risk.
Singapore, SingaporeAges 21–69 - NCT00004317RecruitingPhase 4
Treating Congenital Toxoplasmosis With Three Medications
This study tests a combination of three medications (pyrimethamine, sulfadiazine, and leucovorin) to treat toxoplasmosis—a parasitic infection passed from mother to baby during pregnancy. The goal is to see if early treatment prevents serious complications in infected infants.

Common questions
- Are there clinical trials for calcium?
- Yes. Clin2 currently lists 168 recruiting calcium 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 calcium 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 calcium 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.
