Oxalate production in calcium oxalate stone formers
This study looks at how the body makes oxalate (a natural substance that can form kidney stones) in people who have had calcium oxalate stones. You will eat a special diet and stop supplements for a short time to help researchers understand stone formation.
Birmingham, AlabamaAges 18–80 - NCT06683833RecruitingPhase 4
Comparing materials for protecting tooth nerves in deep cavities
This study compares three materials used to protect the nerve inside a deep cavity. If you have a deep cavity in a live tooth, you may be able to join and help find which material works best.

Study of gut oxalate absorption in calcium oxalate kidney stone patients
This study looks at how your gut absorbs oxalate, a natural substance in many foods that can lead to kidney stones. By eating special diets and pausing certain supplements, researchers can measure your oxalate absorption. This may help find better ways to prevent kidney stones.
Birmingham, AlabamaAges 18–80 - NCT06330246Recruiting
Testing a gut bacteria treatment for calcium oxalate kidney stones
This study tests whether giving a specific gut bacteria can help people with calcium oxalate kidney stones. It looks at whether the bacteria can change how the body processes oxalate, which may reduce stone formation.
Birmingham, AlabamaAges 18–80 - NCT07571837Recruiting
Nano-medication to reduce inflammation after root canal retreat
This study tests a special nano-sized (extremely tiny) medication placed inside a tooth after a previous root canal treatment failed. The goal is to reduce inflammation and swelling in the bone around the tooth's tip so it can heal better.
Cairo, Nasr CityAges 20–40 - NCT05283850RecruitingPhase 2/Phase 3
Study for certain adult cardiac arrest patients
This trial is for adults who have a specific type of cardiac arrest called PEA when EMS arrives. It tests whether the study approach can improve outcomes after this kind of arrest.

Checking coronary calcium to study late heart blood vessel changes
This study looks at coronary calcium (a signal seen on heart scans) to help measure early or late heart blood-vessel problems in people who had cancer treatment as children or young adults. The goal is to better understand who may be at higher risk years later, especially after radiation or certain chemotherapy.

Erzurum, ErzurumAges 18–65 - NCT06531278RecruitingPhase 2
Adebelimab plus chemo for first-line pancreatic cancer with liver spread
This trial tests a combination of immunotherapy (adebelimab) and chemotherapy drugs (irinotecan liposome, oxaliplatin, fluorouracil, and calcium folinate) as a first treatment for pancreatic cancer that has spread to the liver. The goal is to see if this combination is safe and effective.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07748676Recruiting
Comparing two rinsing solutions for deep cavities with tooth pain
This study tests whether rinsing the inside of a painful tooth with a special solution (calcium hypochlorite or sodium hypochlorite) after removing the damaged nerve tissue helps preserve the tooth and reduce pain.
