This study compares different ways to control pain around the time of minimally invasive esophagus surgery. It may help find a method that controls pain better and improves recovery after surgery.
BeijingAges 18–75 - NCT05504837RecruitingPhase 1
Test KB407 inhaled treatment for adults with cystic fibrosis
This Phase 1 study tests the safety of KB407 and how it works in adults with cystic fibrosis (CF). It may help researchers understand whether this inhaled treatment could become a future option for CF.
Gainesville, FloridaAges 18 years+ - NCT05507411RecruitingPhase 2
Watch-and-wait after chemo-radiation plus immunotherapy for esophagus cancer
This Phase 2 study tests whether adding an immunotherapy drug (camrelizumab) to standard chemo-radiation can help some people with operable esophagus cancer avoid immediate surgery, using a “watch and wait” approach. If it works, it may reduce the need for early surgery for carefully selected patients.
Hanzhou, ZhejiangAges 18–75 - NCT05509777RecruitingPhase 3
Mirikizumab for children with active Crohn’s disease
This study tests mirikizumab to reduce inflammation and symptoms in children with Crohn’s disease that is currently active. It may help if your Crohn’s has not improved enough (or stopped working) with at least one other Crohn’s medicine.
Los Angeles, CaliforniaAges 2–17 - NCT05514769Recruiting
Surgery type comparison for early-to-mid stomach cancer
This trial compares two different stomach cancer surgeries after removing the tumor, to see which works better for patients with stomach adenocarcinoma. It may help determine the safest approach and best recovery outcomes for people whose cancer has not spread.
Nanchong, SichuanAges 18–85 - NCT05516628RecruitingPhase 2
Adjuvant atezolizumab plus bevacizumab after liver cancer surgery
This trial studies whether adding atezolizumab and bevacizumab after complete liver cancer surgery can lower the chance the cancer comes back. It also uses “multi-omics” tests (special lab tests on your tissue/blood) to help predict who is more likely to respond or resist treatment.
SingaporeAges 21–90 - NCT05517655RecruitingPhase 4
Cystic fibrosis blood/sweat check using MRI in children
This study looks at new “imaging biomarkers” (MRI measurements) in children with cystic fibrosis (CF). It mainly aims to see how MRI findings might relate to starting the recommended CF triple-combination therapy.
Kansas City, KansasAges 6–8 - NCT05518643Recruiting
Testing a stress-reducing recovery plan for pancreatic surgery patients
This trial tests how well a structured hospital recovery plan (called ERAS) works for people having pancreatic surgery. It looks at stress and recovery outcomes to see if patients may do better with this approach.
LarissaAges 18 years+ - NCT05518903RecruitingPhase 2
Scan test to see tumor-support cells in pancreatic cancer
This trial tests a special imaging scan (a PET/CT with a tracer called 68Ga-FAPI-46) to look at “cancer-support” cells in people with localized pancreatic ductal adenocarcinoma. It may help doctors better understand the tumor and how it responds before surgery after initial treatment.
Rochester, MinnesotaAges 18 years+ - NCT05519683RecruitingPhase 2/Phase 3
Home electrical stimulation for constipation IBS pain
This trial tests whether a home device that uses mild skin electrical stimulation can reduce belly pain from IBS with constipation. It also checks whether the treatment is safe and helpful for symptom relief over the study period.
Ann Arbor, MichiganAges 18 years+ - NCT05519475RecruitingPhase 2
Gene-silencing medicine trial for adults with MASH and liver scarring
This Phase 2 study tests a gene-silencing treatment to improve chronic liver disease called MASH, especially in people with certain genetic risk. You may be eligible if you have MASH with moderate-to-advanced scarring and specific test results, and if other liver causes and recent substance/alcohol issues don’t apply.
Chandler, ArizonaAges 18–75 - NCT05520788Recruiting
Genetic test-guided treatment for advanced bile and liver cancers
This study looks at using a genetic test (next-generation sequencing) to find cancer gene changes in stage IV hepatobiliary cancer. If there is a matching approved medicine, the study follows how well the “right drug for the right mutation” helps patients receiving palliative care.
Wuhan, HubeiAges 18 years+ - NCT05523245Recruiting
AI MRI test to predict treatment response in rectal cancer
This study uses an AI computer program to read special MRI images and predict how well treatment (given before surgery) will work for people with locally advanced rectal cancer. It may help doctors better plan who benefits most from neoadjuvant therapy (treatment before surgery).
Guangzhou, GuangdongAges 18 years+ - NCT05523947RecruitingPhase 1/Phase 2
Study drug for HER2-positive solid tumors, with dose changes
This early-stage study tests YH32367, a drug for people whose cancer is HER2-positive. It aims to find a safe dose and see whether it can shrink HER2-positive cancers that have spread or are hard to treat.
Boston, MassachusettsAges 18 years+ - NCT05524428Recruiting
Test to improve colorectal cancer screening at community clinics
This study tries to reduce barriers to colorectal cancer screening by using a repeated “test and improve” approach with clinic staff. If you work in roles that support screening at participating community health centers, you may be eligible to help implement and evaluate these changes.
Boston, MassachusettsAges 18 years+ - NCT05524090Recruiting
Program to prepare for surgery in locally advanced pancreatic cancer
This trial studies an “implementation program” to help patients with locally advanced pancreatic cancer get ready for the next steps after chemotherapy. It may help improve care planning and outcomes for people whose cancer has not grown after initial treatment.
Amsterdam, North HollandAges 18 years+ - NCT05525598Recruiting
Online therapy for severe body–mind symptom disorders
This trial tests an internet-based treatment program for people with moderate-to-severe functional somatic disorders (long-lasting physical symptoms linked to how the body and brain interact). It may help reduce symptoms and improve day-to-day functioning by offering structured support online.
Aarhus C, DenmarkAges 18–60 - NCT05526144RecruitingPhase 2
Thyroid hormone treatment for fatty liver in Veterans
This trial tests whether thyroid hormone can improve nonalcoholic steatohepatitis (fatty liver with inflammation) in Veterans. You may be asked to have a medically needed liver biopsy, and the study also focuses on safety in people with related conditions like diabetes and heart risks.
Columbia, MissouriAges 18–75 - NCT05528471Recruiting
Test whether fructose affects fatty liver in teens
This study looks at how fructose (a type of sugar) may affect fatty liver disease (NAFLD) in teens with obesity. The goal is to learn whether fructose changes liver health, using MRI/MRS scans to measure the liver.
Edmonton, AlbertaAges 12–18 - NCT05528783Recruiting
Testing FIT-DNA to guide follow-up after colon cancer surgery
This trial checks a stool test called FIT-DNA after colorectal (colon) cancer surgery. It aims to see whether this test can help doctors monitor for recurrence during follow-up and decide how closely to watch.
Guangzhou, GuangdongAges 18–80 - NCT05528952RecruitingPhase 2
Vaccine plus immunotherapy for unresectable liver cancer
This Phase 2 trial studies whether adding a cancer vaccine (to help the immune system recognize your tumor) to two medicines—atezolizumab and bevacizumab—can better control unresectable or advanced liver cancer. It’s for people who haven’t had prior whole-body (systemic) cancer treatment.
BesançonAges 18 years+ - NCT05529615Recruiting
Blood DNA test guides chemotherapy after colon cancer surgery
This trial checks a blood test called circulating tumor DNA to help choose the best time and approach for chemotherapy after colon cancer surgery. It aims to reduce recurrence by identifying people who may benefit from treatment based on changes seen in the blood.
Beijing, Beijing MunicipalityAges 18–75 - NCT05530070Recruiting
Study diet effects on heart risk in celiac disease
This study looks at how celiac disease and gluten-free (GFD) or gluten-containing diets affect blood and cardiovascular (heart and blood vessel) risk factors. It may help researchers understand which diet habits are most important for heart health in people with celiac disease.
