TU2218 with Keytruda for advanced solid tumors
This trial studies TU2218 taken with Keytruda (pembrolizumab) in adults with advanced solid cancers that have limited treatment options. The goal is to see if the combination can shrink tumors and is safe enough to keep using.
San Antonio, TexasAges 18 years+ - NCT05785793Recruiting
Autoimmune hepatitis study for people in China
This study follows people with autoimmune hepatitis (a condition where the immune system attacks the liver) and requires key blood test results at diagnosis. It may help doctors better understand this disease and how it progresses in patients in China.
Shanghai, Shanghai MunicipalityAges 14 years+ - NCT05786716RecruitingPhase 2/Phase 3
Trastuzumab plus pertuzumab for HER2-mutated cancers
This trial tests whether combining trastuzumab and pertuzumab can treat cancers that have HER2 amplification or an activating HER2 mutation. It looks at people ages 12 and older, and may include both children/teens and adults, using the study drug based on their HER2 test results.
BelfastAges 12 years+ - NCT05787197Recruiting
Blood test to guide treatment after colon cancer liver surgery
This trial studies a blood test (called ctDNA) in people with colon cancer that has spread to the liver and is being removed with curative surgery. The goal is to see how the blood test can help with planning and improving treatment after surgery.
BesançonAges 18 years+ - NCT05786924RecruitingPhase 1/Phase 2
Targeted cancer drug study for RAS/RAF mutation-positive tumors
This Phase 1/2 study tests S241656 (a targeted cancer medicine) in people whose cancers have certain “RAS/RAF” gene changes. It may help shrink tumors or control cancer growth, and also finds the safest dose and best way to use the drug.
Gilbert, ArizonaAges 18 years+ - NCT05789433Recruiting
Aerobic exercise study after colon or rectal cancer surgery
This trial studies whether a supervised aerobic exercise program helps muscles “remodel” (change/strengthen) after colon or rectal cancer treatment. It may help people improve physical function during recovery, but you can only join if it’s safe for you and you can follow the study plan.
Orlando, FloridaAges 18 years+ - NCT05789485RecruitingPhase 2
Exercise program to reduce treatment side effects in GI cancer
This trial studies whether a structured exercise plan can lessen side effects from chemotherapy in people with colorectal or stomach/esophagus solid tumors. If you’re about to start chemotherapy, the study will check whether exercising helps you feel and function better during treatment.
Hartford, ConnecticutAges 18 years+ - NCT05791487Recruiting
Diet plus oral budesonide for mild to moderate ulcerative colitis
This trial studies whether combining a specific diet with an oral steroid called budesonide can calm symptoms in people with mild to moderate ulcerative colitis. It may help reduce inflammation in the colon while building on stable current treatments.
AfulaAges 17–65 - NCT05792267Recruiting
AI system for pancreas scans during endoscopic ultrasound
This trial tests a new computer (deep-learning) system to help analyze pictures from an endoscopic ultrasound scan of the pancreas. It may improve how the scan is done or interpreted, depending on study results.
Changsha, HunanAges 18–80 - NCT05793203Recruiting
Tests noninvasive checks to spot liver transplant complications early
This study looks at how well noninvasive tests (tests that don’t require surgery or taking tissue) can detect complications after a liver transplant. It may help patients and teams find problems earlier using safer, easier monitoring.
RomeAges 18–75 - NCT05793554Recruiting
AI checks cancer type during rectal surgery in real time
This study tests an AI system that helps identify cancer or polyp findings during rectal surgery or assessment, using real-time information. It may help surgeons classify tissue more accurately while you are already getting treatment.
Dublin, IrelandAges 18 years+ - NCT05794048Recruiting
Study of blood and tumor features in liver and pancreatic cancers
This trial looks at a patient’s “metabolic profile” (how the body’s chemicals are used) in people with certain liver and pancreatic tumors. It may help doctors better understand these cancers and improve how they are evaluated for treatment.
ClichyAges 18 years+ - NCT05797077RecruitingPhase 3
After-surgery blood test–guided therapy for colon cancer liver spread
This Phase 3 trial tests whether an added “maintenance” treatment after liver surgery can help prevent colorectal cancer from coming back. It is only for people whose blood test (ctDNA) still shows signs of cancer after their operation.
Guangzhou, GuangdongAges 18–75 - NCT05797467RecruitingPhase 3
After-surgery chemo plus targeted therapy for colon cancer
This Phase 3 trial studies whether adding targeted therapy to standard chemotherapy after surgery helps people with stage T3-4, N2 colon cancer live longer or have fewer cancer returns. You would be assigned to receive chemotherapy with targeted therapy or chemotherapy alone, based on the study plan.
Guangzhou, GuangdongAges 18–75 - NCT05798962Recruiting
Study of muscle repair changes after calf or hamstring injury

Nutrition support program for people with esophageal cancer
This trial tests whether an “NST whole-course” nutrition management plan can improve nutrition status and reduce side effects during treatment for stage II–III esophageal cancer. It may help you stay stronger and tolerate cancer therapy better by carefully monitoring and adjusting nutrition.
Nanjing, JiangsuAges 18–75 - NCT05802407Recruiting
ctDNA blood test monitoring after pancreatic cancer surgery
This study looks at whether a special blood test (ctDNA) can detect tiny amounts of pancreatic cancer left after surgery. It may help doctors monitor who is at higher risk of cancer coming back, so they can tailor follow-up and treatment timing.
BeijingAges 18 years+ - NCT05802394Recruiting
Using blood tests to track cancer after pancreatic treatment
This trial studies whether a blood test (ctDNA, a DNA signal from tumors) can help track how pancreatic cancer responds during planned conversion therapy. It may help doctors spot treatment response earlier and guide next steps.
BeijingAges 18 years+ - NCT05802264RecruitingPhase 1
Inhaled amphotericin B for healthy volunteers and cystic fibrosis
