Comparing two stomach protectors after stem cell transplant
This study compares two medications, GMPA and PPI, that protect the stomach during a stem cell transplant. It aims to see which one is better at preventing stomach problems and reducing the risk of a complication called graft-versus-host disease (aGVHD), where donor cells attack the patient's body.
HangzhouAges 12–70 - NCT07793500RecruitingEarly Phase 1
Nebulized drug for lung metastases from solid tumors
This study tests a new drug given as a mist you breathe in, for people whose cancer has spread to the lungs. The goal is to see if it can shrink tumors or slow their growth.
BeijingAges 18–75 - NCT07314593Recruiting
Fish oil for preventing colds and respiratory infections
This trial tests whether taking fish oil with free fatty acids can help healthy adults avoid colds and other respiratory infections. If you are generally healthy and willing to take fish oil capsules daily, you may be able to join.
ReykjavikAges 18–80 - NCT05624450RecruitingPhase 3
Test drug tozorakimab for hospitalized viral lung infection needing oxygen
This Phase 3 study tests tozorakimab to see if it helps people hospitalized with a viral lung infection that is causing low oxygen levels. You might qualify if you still need supplemental oxygen when the study starts.
Birmingham, AlabamaAges 18 years+ - NCT06395103RecruitingPhase 1/Phase 2
Zilovertamab vedotin for blood cancers and solid tumors
This trial tests a new drug called zilovertamab vedotin for children and young adults with certain blood cancers or solid tumors. The drug is designed to target and kill cancer cells, and the study will see if it is safe and effective.
Los Angeles, CaliforniaAges 6 months–25 years - NCT07700381Recruiting
Fermented dairy and gut bacteria study
This study tests if a fermented dairy product can increase the amount of a healthy gut bacteria called Bifidobacterium. If you are healthy, age 45-60, and willing to follow the diet rules, you may be able to join.
DijonAges 45–60 - NCT06479837Recruiting
Study using tonsil tissue to understand infections
This study uses tonsil tissue that is removed during a routine tonsillectomy to grow tiny 'organoids' in the lab. Researchers will study how germs interact with human cells, which could lead to better treatments for infections.
Bethesda, MarylandAges 2–120 - NCT07149428Enrolling by invitation
Deep study of smell loss causes using brain scans
This study uses brain imaging and electrical recordings to understand the brain's role in smell loss from any cause—like COVID, sinus problems, or chemotherapy. You may be eligible if you have any degree of smell loss lasting under a year.
Bethesda, MarylandAges 18–99 - NCT07711535Recruiting
Developing Sepsis Quality Indicators for Sub-Saharan Africa
This study aims to develop quality indicators for early sepsis care in Sub-Saharan Africa using a structured expert consensus process (modified Delphi). Healthcare professionals with experience in sepsis care or research in low- and middle-income countries are invited to participate in online survey rounds.
KumasiAges 18 years+ - NCT07215858RecruitingPhase 2
Testing a new flu vaccine against H1N1 flu
This study tests an experimental flu vaccine (BPL-1357) in healthy volunteers who will later be exposed to H1N1 flu virus in a controlled setting, to see if the vaccine can prevent or reduce illness.
Bethesda, MarylandAges 18–55 - NCT07461818Recruiting
Quick treatment for cervical pre-cancer
This trial tests a new way to quickly diagnose and treat cervical pre-cancer using a point-of-care device. It may help women who are HPV-positive avoid a separate treatment visit.
