This Phase 2 trial tests two drug combinations for people with a specific genetic mutation (EGFR) in advanced non-small cell lung cancer. One group receives amivantamab plus lazertinib as first treatment; the other gets amivantamab plus chemotherapy after previous treatment stopp…

This phase 2 trial tests the drug everolimus in 67 people with vascular anomalies (abnormal blood vessels) that haven't responded to standard treatments. The goal is to shrink the lesions and improve symptoms. Participants take everolimus daily for 6 months, with doses adjusted b…

This study compares two types of minimally invasive surgery for early-stage stomach cancer: a newer robotic method using fewer incisions (reduced-port) and the standard laparoscopic method. About 538 patients will be randomly assigned to one of the two surgeries. The main goal is…

This study looks at 4,400 people who had a heart attack and got a stent. It tests two drug strategies: one to lower bleeding risk by adjusting blood thinners, and another to lower cholesterol using a milder statin plus ezetimibe. The goal is to find the safest and most effective …

This study tests a new approach for people with end-stage heart failure and permanent atrial fibrillation who are waiting for a heart transplant or heart pump. Participants will receive either a standard implantable defibrillator (ICD) alone or an ICD plus a special pacing lead a…

This early-stage trial tests a new treatment called AB-201 for advanced HER2-positive stomach or gastroesophageal junction cancer. AB-201 uses specially engineered natural killer cells to target and kill cancer cells. The study will enroll 18 adults whose cancer has not responded…

This study is for people with advanced biliary tract cancer whose disease is stable after initial chemotherapy plus immunotherapy. It compares four different maintenance treatments: immunotherapy alone or combined with lenvatinib, venadaparib, or interleukin-2. The goal is to fin…

This study tests a new type of radiation called carbon ion radiotherapy given before surgery for soft tissue sarcoma. The goal is to see if it is safe and can reduce wound problems after surgery while better controlling the tumor. About 60 adults with sarcoma that can be removed …

This study tests whether giving a single dose of intravenous iron the day after heart surgery can reduce the chance of long-term anemia. About 180 adults with low iron or anemia before surgery will be randomly assigned to receive either the iron treatment or a placebo. The main g…

This study tests if burning extra spots outside the main heart veins can better control persistent atrial fibrillation (a type of irregular heartbeat). About 406 adults having their first ablation will be split into two groups: one gets standard vein isolation, the other gets add…

This study tests whether an artificial intelligence (AI) tool can help emergency room doctors interpret heart CT scans more accurately. About 530 adults with chest pain and intermediate risk of a heart attack will be randomly assigned to have their scans read with or without AI a…

This study tests whether an artificial intelligence-enhanced ECG (SmartECG-AFrisk) can detect atrial fibrillation (AF) earlier than usual care in 1,230 adults with symptoms like palpitations or dizziness but no prior AF diagnosis. Participants are randomly assigned to either stan…

This study compares apixaban alone versus apixaban plus clopidogrel for 30 days in people who have had a stroke and have both atrial fibrillation and atherosclerosis. About 586 participants will be randomly assigned to one of the two treatments. The goal is to see if the combinat…

This study compares two methods of pain control after total knee replacement: a single injection of numbing medicine versus a continuous drip through a small tube for 48 hours. About 78 adults aged 40-80 will be randomly assigned to one of the two groups. The goal is to see which…

This study tests if a surgeon can numb the knee during replacement surgery as effectively as an anesthesiologist using ultrasound. 48 adults having both knees replaced will get one method on each knee. The goal is to see if the surgeon's technique provides equal pain relief and r…

This study tests if listening to binaural beats (special sounds that calm the brain) can lower the amount of sedative drug needed during a C-section. Pregnant women having a C-section under spinal anesthesia often feel anxious and get a drug called midazolam, which can cause side…

This study tests a smartphone app called One.Dr to see if it can reduce the drop in blood pressure that happens when people with orthostatic hypotension stand up. About 86 adults who feel dizzy when standing will use either the real app or a sham version for 6 weeks. The goal is …

This study compares two sedatives, remimazolam and midazolam, to see which one causes less confusion (delirium) after heart valve surgery in people aged 65 and older. Delirium affects up to 70% of older heart surgery patients and can lead to longer hospital stays and memory probl…

This study compares how much radiation doctors are exposed to during heart procedures (PCI) when using the left distal wrist versus the right wrist for artery access. About 748 patients scheduled for PCI will take part. The goal is to see if the left wrist approach reduces radiat…
