This study compares three different flu vaccines in 60 adults with blood cancers like leukemia or lymphoma. The goal is to see which vaccine triggers the strongest immune response in people with weakened immune systems. Participants will receive one of the vaccines and have their…

This study tests whether a personalized blood-thinner plan can reduce bleeding in people with coronary artery disease who have received a heart stent. About 3,944 participants will either get the usual dual antiplatelet therapy (two blood thinners) or a shorter course followed by…

This study tests whether using artificial intelligence (AI) to analyze ultrasound images during heart stent placement can reduce future heart problems. About 3,000 adults with coronary artery disease will receive a stent guided by AI-enhanced intravascular ultrasound. Researchers…

This phase 2 trial tests an oral form of paclitaxel (Liporaxel) in 28 adults with advanced gastrointestinal stromal tumors (GIST) that no longer respond to three standard drugs: imatinib, sunitinib, and regorafenib. The study focuses on patients whose tumors have low levels of a …

This phase 2 trial tests a combination of two drugs—rivoceranib and paclitaxel—in 48 adults with advanced gastrointestinal stromal tumors (GIST) that have a specific protein marker (high P-glycoprotein) and have stopped responding to three standard treatments. The goal is to see …

This study tests a combination of three chemotherapy drugs (docetaxel, oxaliplatin, and S-1) given before surgery to people with advanced stomach cancer that cannot be removed right away. The goal is to shrink the tumor enough so that surgery can remove it completely. About 63 ad…

This study tests the drug temozolomide in people with a rare type of advanced stomach cancer called SDH-deficient GIST. About 29 adults will receive the drug to see if it shrinks tumors and is safe. The goal is to control the disease, not cure it.

This phase 3 trial is testing whether an iron infusion called ferric carboxymaltose can safely and effectively treat iron-deficiency anemia in people with advanced stomach cancer who are receiving palliative chemotherapy. The study plans to enroll 330 participants and will measur…

This study tests the drug lenvatinib in 48 adults with advanced gastrointestinal stromal tumors (GIST) that have stopped responding to three standard treatments. Participants take lenvatinib capsules daily, and researchers will measure how many patients have their disease control…

This study tests whether adding the drug cilostazol to the usual two blood thinners (aspirin and clopidogrel) can better prevent early stroke recurrence in people who had a stroke caused by narrowed arteries in the brain or neck. About 2,340 adults will be enrolled within 72 hour…

This study tests a new drug, Irpagratinib, added to two standard drugs (Atezolizumab and Bevacizumab) for people with advanced liver cancer that cannot be removed by surgery. The goal is to see if the combination is safe and shrinks tumors. About 33 adults with a specific genetic…

This study compares two pacemaker strategies for people with sick sinus syndrome and AV conduction delay. Participants will be randomly assigned to receive either left bundle branch area pacing (LBBAP) or minimized ventricular pacing (MVP). The goal is to see which method leads t…

This study tests whether a fecal microbiota transplant (FMT) combined with the immunotherapy drug nivolumab can help people with advanced solid cancers that stopped responding to prior treatment. About 50 participants will receive the combination to see if it can shrink tumors. T…

This study tests a combination of three drugs—lenvatinib, nivolumab, and chemotherapy—in people with advanced stomach cancer that has spread to the lining of the abdomen and caused fluid buildup (ascites). The goal is to see if this triple therapy can shrink tumors and help patie…

This study tests whether a shorter, contrast-enhanced MRI scan can detect liver cancer recurrence as well as standard CT scans in people who have been cancer-free for over two years after treatment. About 455 participants will receive both scans to compare their accuracy. The goa…

This study tests a wearable ECG patch (MEMO Patch) to see if it can detect atrial fibrillation—a heart rhythm issue that raises stroke risk—in 100 people who had a stroke with no known cause. Participants wear the patch for up to 14 days at home, and results are compared with sta…

This study is testing a special type of PET scan (called FES PET/CT) to see if it can better find cancer that has spread to other parts of the body in people with a certain type of breast cancer. The study includes 85 adults with low-grade, estrogen receptor-positive stage III br…

This study tests a smartphone app called Tuntun Rehabilitation Assistant to help people who have been in the intensive care unit (ICU) regain strength and mobility. About 70 adults from two hospitals in South Korea will use the app for daily 30-minute rehab sessions. Researchers …

This study looks at how gut bacteria affect immunotherapy in people with advanced solid tumors. It has two parts: first, finding bacterial markers linked to treatment response; second, testing if fecal transplants from healthy donors can make immunotherapy work better. About 60 a…

This study follows over 500 adults with type 2 diabetes who had a heart CT scan years ago. Researchers will repeat the scan to see how plaque builds up in heart arteries over time and identify factors that increase risk. The goal is to better understand heart disease in diabetes,…

This study is collecting blood and tumor samples from 50 people with advanced liver cancer who are receiving immunotherapy. Researchers will analyze the samples to find genetic and immune system markers that might predict how well the treatment works. The goal is to better unders…

This observational study will follow 400 patients with mitral stenosis who undergo a procedure called percutaneous mitral balloon commissurotomy (PMBC), where a balloon is used to open a narrowed heart valve. Researchers want to see how patients fare afterward and find the best w…
