Los Angeles, CaliforniaAges 18–75 - NCT07125729Recruiting
Early cancer detection test for colorectal cancer
This trial uses two blood tests (Signatera and Haystack) to look for tiny bits of cancer DNA after surgery, to find out if the cancer comes back as early as possible. People with stage II, III, or IV colorectal cancer who have had or will have surgery to remove their tumor may join.
Goodyear, ArizonaAges 18 years+ - NCT07035691Recruiting
New markers to better diagnose colorectal cancer referrals
This study looks for new markers in the blood or stool to help diagnose colorectal cancer earlier. It is for people who have been referred urgently because their doctor suspects lower bowel cancer.
London, EnglandAges 18 years+ - NCT05535361Recruiting
Testing a bowel device for short bowel syndrome patients
This trial studies whether the Eclipse XL1 system is safe and may help people with short bowel syndrome, in both children and adults. It will check how well the approach works and watch for side effects over the study period.
Palo Alto, CaliforniaAges 3 months–65 years - NCT07499258Recruiting
Axonics R20 study for fecal incontinence
This trial is testing how well a device called Axonics R20 works for people with fecal incontinence. It may help if you have this condition and are willing to follow the study procedures.
New York, New YorkAges 18 years+ - NCT06526819RecruitingPhase 1/Phase 2
New drug SMP-3124LP for advanced solid tumors
This trial tests a new drug called SMP-3124LP for people with advanced solid tumors that no longer respond to standard treatments. It is given in two phases: first to find the best dose (dose escalation) and then to see how well it works in specific cancer types (dose expansion).
Los Angeles, CaliforniaAges 18 years+ - NCT06095128RecruitingPhase 4
Vedolizumab and tofacitinib study for ulcerative colitis
This trial tests if combining two medicines, vedolizumab and tofacitinib, helps control moderate to severe ulcerative colitis. It may be an option if other treatments, like anti-TNF drugs, haven't worked well for you.
Dothan, AlabamaAges 18–65 - NCT06993454Recruiting
Exercise and blood sugar in type 2 diabetes with fatty liver
This study looks at how a single session of exercise affects the body's natural sugar production in people with type 2 diabetes and fatty liver. It may help us find better ways to control blood sugar and treat fatty liver.
Orlando, FloridaAges 25–55 - NCT05417594RecruitingPhase 1/Phase 2
Targeted drug study for advanced cancers with genetic changes
This Phase 1/2 study tests AZD9574 alone or with other cancer treatments in people with advanced solid tumors. It focuses on cancers with specific DNA repair gene changes (like BRCA1/2) or other matching tumor features, and aims to see if the treatment can shrink tumors and improve outcomes.
La Jolla, CaliforniaAges 18–130 - NCT04775706RecruitingPhase 2
Test of sonefpeglutide for people with short bowel syndrome
This Phase 2 study tests whether sonefpeglutide is safe and how the body handles it (pharmacokinetics) in people with short bowel syndrome. It may help people who still need nutrition through a tube because their intestinal condition is stable.
Boston, MassachusettsAges 18 years+ - NCT06372613Recruiting
LRG protein and ulcerative colitis remission
This study looks at a protein called LRG in your blood or tissue to see if it can tell if your ulcerative colitis is in remission (quiet or not active). This might help doctors better monitor and treat UC in the future.
KomaganeAges 20–90 - NCT07399886Recruiting
Plant or dairy shake for cancer and heart patients at risk of malnutrition
This study compares two types of nutrition shakes (one plant-based and one dairy-based) for patients who are undernourished due to cancer, lung disease, heart problems, or recovery from surgery. It aims to see if the plant-based shake is just as good as the dairy shake.
Nijmegen, GelderlandAges 18 years+ - NCT06696768RecruitingPhase 1
New drug plus standard chemotherapy for advanced colorectal cancer
This trial combines a new experimental drug (emavusertib) with standard chemotherapy (FOLFOX plus bevacizumab) for people with stage IV colorectal cancer who have not yet received chemotherapy. The goal is to see if the combination is safe and effective, potentially offering a new first-line treatment option.
Gainesville, FloridaAges 18 years+ - NCT05592626RecruitingPhase 1/Phase 2
T cell activator STAR0602 for advanced solid tumors
This study tests an experimental drug called STAR0602 that aims to boost your immune system's T cells to fight advanced solid tumors. It's for patients whose cancer has not responded to standard treatments or for whom such treatments are not suitable.
Sacramento, CaliforniaAges 18 years+ - NCT05867329RecruitingPhase 4

Study of metarrestin for advanced solid tumors
This study tests an experimental drug called metarrestin for people with solid tumors that have spread or come back after standard treatment. It may help by targeting a protein involved in cancer cell growth.
Fairway, KansasAges 12–120 - NCT07600125Recruiting
Stool test to screen for digestive tract cancers
This study tests whether a stool sample can help detect early signs of cancers in the stomach, colon, and related organs. Researchers will compare stool test results with findings from standard camera procedures to see if this non-invasive approach might catch cancer earlier.
Xi'an, ShaanxiAges 18 years+ - NCT03571373Recruiting
