This study checks if you are at high risk for stomach cancer. You will give blood samples and have a stomach exam (endoscopy) to look for early signs.
Duarte, CaliforniaAges 40–80 - NCT06864195Recruiting
Breath test for liver cancer detection
This study tests a simple breath test to detect liver cancer and monitor liver health. It is looking for patients with liver cancer, liver cirrhosis, primary sclerosing cholangitis, or people with normal livers to see if the breath test can help tell the difference.
LondonAges 18 years+ - NCT07243262Recruiting
Breath test for pancreatic cancer detection
This trial tests whether a simple breath test can help detect pancreatic cancer earlier. If you have been referred for possible pancreatic cancer, you may be able to take part.
LondonAges 18 years+ - NCT07202780Enrolling by invitation
MS and Muscle Strength in Breathing and Legs
This study looks at how MS affects the strength of your breathing muscles and leg muscles. If you join, you will have tests to measure your muscle strength, walking ability, and fatigue. This may help doctors understand how to better treat MS-related weakness.

IslamabadAges 40–65 - NCT05890911Enrolling by invitation
Studying dopamine pathways in breathing problems during sleep
This study looks at how dopamine-related brain pathways may be involved in sleep-related breathing problems. It may help researchers better understand what causes these conditions and how to evaluate them with sleep testing.
WroclawAges 18–80 - NCT06554353Recruiting
Breathing and exercise tests for shortness of breath
This study looks at how well two breathing tests work for people who have shortness of breath. You will do a breathing test and an exercise test to help doctors better understand your symptoms.
