New ways to check if liver cancer ablation worked
This study tests new criteria for evaluating how well thermal ablation (using heat to destroy cancer nodules) worked in people with hepatocellular carcinoma (HCC, a type of liver cancer). It aims to improve follow-up imaging with contrast-enhanced ultrasound (CEUS) or CT/MRI to see if the treatment was successful.

Pressurized chemo spray for appendix or colorectal cancer spread in abdomen
This trial tests a new way to deliver chemotherapy directly into the abdomen as a pressurized spray, using a drug called mitomycin. It is for people with appendix or colorectal cancer that has spread to the lining of the abdomen and cannot be removed by surgery.
Goodyear, ArizonaAges 18 years+ - NCT07269626RecruitingPhase 2
PULSAR therapy for pancreatic cancer
This trial tests whether adding a special type of radiation therapy (PULSAR) to standard chemotherapy can help control pancreatic cancer that has not spread far. It is for people who have already completed a few rounds of chemo without their cancer growing.
Seoul, Select Province/StateAges 19 years+ - NCT07270237Recruiting
New ultrasound imaging for pancreas and thyroid
This study tests new ultrasound methods to better see the pancreas and thyroid. It includes people at high risk for pancreatic cancer, those with pancreatic cancer, those with a thyroid nodule, and healthy volunteers.
Basking Ridge, New JerseyAges 18 years+ - NCT07274631Recruiting
Study of inflammatory lung diseases
This study collects information from people with various inflammatory lung conditions, like asthma or COPD, to better understand them and improve treatment. Healthy volunteers are also needed for comparison.
ReimsAges 18 years+ - NCT07277907RecruitingPhase 3
Lubiprostone for slow-transit constipation in adults
This study tests whether lubiprostone (Amitiza) can help people with slow-transit constipation. If you have few bowel movements and tests show that stool moves slowly through your colon, this treatment may help you go more regularly.
Bishan, Chongqing MunicipalityAges 18 years+ - NCT07277322RecruitingPhase 1/Phase 2
Two immunotherapy drugs before surgery for MSS colorectal cancer with liver spots
This trial tests a combination of two immunotherapy drugs (Dupilumab and Toripalimab) before surgery for people with MSS colorectal cancer that has spread to the liver. The goal is to see if this treatment can shrink the liver tumors and help the body's immune system fight the cancer.
New York, New YorkAges 18 years+ - NCT06889805Recruiting
HDV screening for HIV and hepatitis B patients
This study tests whether people with both HIV and chronic hepatitis B should be checked for a third liver virus called HDV (hepatitis D). It helps find hidden infections so they can get the right care.

Checks heart and lung effects after chest radiation
This study looks at how chest radiation treatment affects the heart and lungs in people with certain lung or esophagus cancers. It may help doctors better predict and prevent these side effects during curative (aimed at cure) radiotherapy.
LeuvenAges 18 years+ - NCT05713994Recruiting
Liver cancer treatments together for unresectable liver tumors
This trial tests a combined treatment plan—chemo delivered to the liver, targeted therapy, anti-VEGF therapy, and immunotherapy—to control unresectable hepatocellular carcinoma (HCC). It may help shrink tumors or slow progression when surgery isn’t possible.
Quanzhou, FujianAges 18 years+ - NCT05776524RecruitingPhase 2
Radiofrequency heat treatment for pancreas cancer spread to other organs
This Phase 2 trial tests whether a device that delivers carefully timed “radiofrequency heat” through the body can slow or control metastatic (spread) pancreatic cancer. You may qualify if you have newly diagnosed metastatic pancreatic cancer and can meet safety and blood-test requirements.
Winston-Salem, North CarolinaAges 18 years+ - NCT06423508Recruiting
Testing stool storage methods and gut bacteria differences
This trial will study how different storage methods affect stool samples for gut bacteria analysis. It aims to understand differences in gut bacteria between people over time. Participation involves providing stool samples.
Vienna, State of ViennaAges 18–70 - NCT06445660Recruiting
Using CT scans to find salvageable bowel in mesenteric ischemia
This trial is testing a new way to use CT scans to identify which parts of the bowel can still be saved in patients with acute mesenteric ischemia. It aims to help doctors make better decisions about whether surgery is needed.
TartuAges 18 years+ - NCT06840067Recruiting
Carbon ion radiotherapy for pancreatic cancer
This trial tests a new type of radiation called carbon ion therapy for people with advanced pancreatic cancer (stages III–IV) that has spread or can't be removed by surgery. It's combined with standard chemotherapy (gemcitabine plus nituzumab) to see if it can help shrink tumors and improve outcomes.
Wuwei, GansuAges 18–80 - NCT06894797Recruiting
Chemo and radiation before and after surgery for rectal cancer
This study tests a sequence of chemotherapy and radiation before and after surgery for rectal cancer. It compares giving more chemo between the end of radiation and surgery (consolidation) versus giving some chemo before radiation starts (induction). The goal is to see which order works better.
BeijingAges 18–75 - NCT05473156RecruitingPhase 1/Phase 2
Study of AP203 for advanced solid tumors that grew despite treatment
This early-phase study tests AP203 (an investigational treatment) to see if it is safe and to look for signs it can shrink or control certain advanced cancers. The study includes a dose-finding part for many solid tumors, and a second part focused on specific lung and head/neck cancers that previously received PD-1/PD-L1 therapy.
TaipeiAges 18 years+ - NCT05984745RecruitingPhase 2
CoQ10 for fatty liver linked to metabolic issues

Liver cancer study after surgery or pre-surgery therapy
This study looks at genetic markers in the blood of people with liver cancer who are having surgery, either right away or after some treatment first. It aims to find out why some patients do better, which could help personalize care.

Breath test to find lung diseases
This study uses a simple breath test to detect different lung diseases. By analyzing the chemicals in your breath, researchers hope to find a faster, non-invasive way to diagnose lung conditions. It may be an option if you have a known lung disease and have a recent CT scan.
