Somatostatin and Diet vs. Stoma After Rectal Cancer Surgery
This trial tests whether using a medication called somatostatin plus a clear liquid diet can safely prevent serious complications after surgery to remove rectal cancer, without needing a temporary opening in the abdomen (stoma). You'll be randomly assigned to receive either somatostatin with diet changes or a stoma, depending on your individual risk factors.
Ezhou, HubeiAges 18–75 - NCT07605819Recruiting
Pancreatic Cancer Screening Test Study in Japan
This study tests a new blood test called the Enzeavour Assay to screen for early signs of pancreatic cancer in people without symptoms. If the test is positive, you may need imaging tests like an ultrasound or CT scan to confirm findings.
Nagakute, Aichi-kenAges 20 years+ - NCT07606547Recruiting
Swallowing Strength Training for Parkinson's Disease
This study tests whether a mouth and throat muscle-strengthening device called EMST helps people with Parkinson's disease who have difficulty swallowing. Stronger throat muscles may make swallowing safer and easier.
MünsterAges 18 years+ - NCT07607119Recruiting
PULSAR radiation plus immunotherapy for advanced gastric cancer
This trial tests combining PULSAR (a type of radiation therapy) with immunotherapy drugs to treat gastric (stomach) cancer that cannot be surgically removed. You must have already completed at least 3 months of chemotherapy with immunotherapy and shown no cancer growth to qualify.
Seoul, Select Province/StateAges 19 years+ - NCT07607353Recruiting
Biodegradable Stents for Primary Sclerosing Cholangitis
This trial tests a new type of stent (a small tube placed in bile ducts) that dissolves on its own over time in patients with primary sclerosing cholangitis (PSC), a rare disease affecting the bile ducts. The goal is to widen narrowed ducts and reduce the need for repeated procedures.
LondonAges 18 years+ - NCT07609680Recruiting
Blood Pressure vs. Heart Output Monitoring During Colon Surgery
This trial compares two ways doctors monitor your body's circulation during colorectal surgery. One method tracks blood pressure; the other tracks how much blood your heart pumps. Researchers want to see which approach leads to better outcomes and fewer complications.
Ankara, Yenimahalle\AnkaraAges 18–80 - NCT07610551Recruiting
Combination therapy for advanced liver cancer
This trial studies whether combining three treatments—an immunotherapy drug (Atezo), a blood-vessel-blocking drug (Bev), and a radioactive bead treatment (SIRT-Y90)—can help patients with advanced liver cancer that cannot be surgically removed. The goal is to see if using all three together works better than using fewer treatments.
Xi’an, ShanxiAges 18 years+ - NCT07610798RecruitingPhase 1/Phase 2
Testing INV-8989 for Advanced Cancers With KRAS G12D Mutation
This early-stage trial tests a new drug called INV-8989 designed to target a specific genetic mutation (KRAS G12D) found in some advanced solid cancers. The study will evaluate whether the drug is safe and if it can help shrink tumors in patients who haven't responded to standard treatments.
Guangzhou, GuangdongAges 18 years+ - NCT07610772RecruitingPhase 1
Safety study of a new hepatitis B antibody for hepatitis D
This early-stage trial tests whether a new monoclonal antibody (a lab-made protein that fights viruses) is safe and effective in people with chronic hepatitis D infection. Hepatitis D only occurs in people who also have hepatitis B, and this new treatment may help control the virus.
