Licorice root gel for root canal infection
This trial tests a natural anti-inflammatory medicine called glycyrrhizin (from licorice root) used inside the tooth during root canal treatment. It aims to see if it helps kill bacteria and reduce infection better than standard medications.
Al MansurahAges 20–60 - NCT06508164Recruiting
International registry for rare RYR2 variants
This study creates a registry for people with rare changes in the RYR2 gene that affect heart function. Researchers will collect information to better understand these conditions and improve care.
San Francisco, CaliforniaAges Any age - NCT06224660RecruitingPhase 1
Gene therapy for heart problems in Duchenne muscular dystrophy
This trial tests an experimental therapy for heart weakness caused by Duchenne muscular dystrophy. It aims to improve how heart cells handle calcium to protect heart function.
Kansas City, KansasAges 18 years+ - NCT06078709RecruitingPhase 2
Pre-surgery radiation and chemo for esophageal cancer
This trial tests a shorter course of radiation combined with chemotherapy (FOLFOX) before surgery for esophageal or stomach-junction cancer. It aims to reduce side effects and still improve outcomes.
Scottsdale, ArizonaAges 18 years+ - NCT03801876RecruitingPhase 3
Proton versus photon radiation for esophageal cancer
This trial compares proton therapy and standard photon (X-ray) radiation for treating esophageal cancer. It looks to see which approach works better and is safer for people who need chemoradiation.
Phoenix, ArizonaAges 18 years+ - NCT04075162Recruiting
Free heart calcium scan program at University Hospitals
This study is looking at people who already received a free coronary artery calcium (CAC) CT scan through a community screening program at University Hospitals. It may help the hospital understand who benefits from offering these no-cost scans.
Cleveland, OhioAges 18–100 - NCT06821997RecruitingPhase 2
Chemotherapy Before Surgery for Borderline Resectable Pancreatic Cancer
This trial is testing a combination of three chemotherapy drugs (NALIRIFOX) given before surgery to shrink borderline resectable pancreatic cancer. The goal is to help make surgery more successful and improve outcomes.
Buffalo, New YorkAges 18 years+ - NCT05593627RecruitingPhase 4
Lithium to improve sleep and thinking after heart surgery
This trial tests whether lithium carbonate can improve sleep and thinking (cognitive function) after heart valve surgery that uses a heart-lung machine. It may help some people who have trouble sleeping or thinking after surgery, but it excludes people with significant sleep or thinking problems before surgery.
Shenyang, LiaoningAges 18–65 - NCT07381998Enrolling by invitation
Effects of total thyroid removal on parathyroid function and quality of life
This study looks at how completely removing the thyroid gland affects the nearby parathyroid glands (which control calcium) and your overall quality of life. If you're having a total thyroid removal and meet a few health conditions, you may be able to join.
Aarhus, Central JutlandAges 18 years+ - NCT05688215RecruitingPhase 1/Phase 2
Zimberelimab and quemliclustat with chemotherapy for pancreatic cancer
This trial studies how well zimberelimab and quemliclustat work together with standard chemotherapy for people with borderline resectable or locally advanced pancreatic cancer. It may help shrink the tumor and make treatment more effective before or around the time surgery is considered for some patients.
Los Angeles, CaliforniaAges 18 years+ - NCT07105930Recruiting
Comparing two ways to treat heavily calcified heart arteries
This trial tests if a special rotating device alone works as well as a more complex approach for treating heavily calcified blockages in the heart arteries. It uses a CT scan to find the right patients.
FrankfurtAges 18 years+ - NCT07696533Recruiting
Comparing two imaging tests for chronic coronary syndrome
This trial sees if a carotid ultrasound is as good as a CT calcium score to detect heart disease in people with chest pain. It may help avoid more expensive or less available scans.
HarrowAges 18 years+ - NCT07491601Recruiting
Preventing low parathyroid after thyroid surgery
This study aims to find ways to detect and prevent low parathyroid function after thyroid surgery. If you are having your whole thyroid removed, joining could help researchers learn how to improve recovery.
Würzburg, BavariaAges 18 years+ - NCT07146464Recruiting
Peptide vs calcium paste for early cavity spots
This trial tests whether a new peptide treatment or a calcium-phosphate paste works better at reversing early white-spot cavities on front teeth. If you're a young adult with early decay on your front teeth, you may be able to join.
Cairo, Cairo GovernorateAges 15–25 - NCT07256691Recruiting
Bioceramic vs. resin sealer for root canal pain
This study tests two types of sealing materials used in root canals (a newer bioceramic one vs. a standard resin one) to see which causes less pain after treatment. If you have an infected, pain-free tooth that needs a root canal, this trial may help guide better care.
Lahore, Punjab ProvinceAges 18–55 - NCT07194837Recruiting
Laser treatment for root canal retreatment healing
This trial tests whether a special laser (810 nm diode) can help heal infections around the root tip after a failed root canal. It is for people who have a single-rooted tooth that needs retreatment.
CairoAges 20–45 - NCT07268742Recruiting
Vitamin D and steroids in endocrine disorders
This study looks at how vitamin D and steroids work in people with different hormone-related conditions. It may help us understand why some people have trouble with vitamin D and how it affects their health.
LeuvenAges 18 years+ - NCT05796739Recruiting
Stress testing once or only when needed for high calcium risk
This study compares two approaches to stress testing in people who feel fine but have high coronary artery calcium on a scan. It may help determine whether testing routinely is better than doing it only if symptoms or concerns arise.
SeoulAges 19 years+ - NCT05826444Recruiting
Study of heart transplant micro-vessel disease using special tests
This trial is for people who have had a heart transplant and are having symptoms or need routine invasive check-ups. It tests an approach aimed at better understanding and monitoring “micro-vessel” problems in the transplanted heart.
BerlinAges Any age - NCT06998368Recruiting
Calcium channel, sleep, and 5G brain health study
This study tests whether a common genetic variation in calcium channels affects how 5G mobile signals influence sleep and brain health. It involves taking a medication (nimodipine) and sleeping in a lab.
Zurich, Canton of ZurichAges 20–40 - NCT05677490RecruitingPhase 3
Chemo options, with or without nivolumab, for HER2-negative stomach cancer
This Phase 3 trial compares two standard chemotherapy regimens for advanced stomach, esophagus, or gastroesophageal junction cancer that is HER2-negative. It also tests whether adding nivolumab (an immune therapy) improves outcomes.
Birmingham, AlabamaAges 18 years+ - NCT06982703Enrolling by invitation
Butyrate for antibiotic-related diarrhea

Common questions
- Are there clinical trials for calcium?
- Yes. Clin2 currently lists 170 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.
