Studying liver cancer response to targeted radiation therapy
This trial is for people with liver cancer (hepatocellular carcinoma) who are about to receive a type of internal radiation therapy called TARE (also known as radioembolization). Researchers want to learn more about how the cancer responds to this treatment using scans and biopsies. You might be a good fit if you have not had any prior treatment for your liver cancer.

Moderate drinking vs. abstention advice for adults
This study compares two approaches for adults who drink regularly: advice on drinking in moderation vs. advice to stop drinking entirely. The goal is to see which approach better prevents major diseases and early death over time.
Pamplona, NavarreAges 50–75 - NCT06338865Recruiting
Lower pressure vs. standard pressure for laparoscopic gynecologic surgery
This trial compares using lower gas pressure during minimally invasive gynecologic surgery to the standard pressure. The goal is to see if lower pressure reduces pain and speeds recovery after surgery.
Los Angeles, CaliforniaAges 18 years+ - NCT06339060RecruitingPhase 3
Chemoradiation and immunotherapy to save the esophagus
This trial tests whether adding immunotherapy to standard chemoradiation (chemotherapy plus radiation) can help preserve the esophagus and avoid surgery in people with resectable esophageal cancer. It aims to see if this combination is safer and more effective than current treatment.
ShanghaiAges 18–75 - NCT06339593RecruitingEarly Phase 1
Using MRI to Monitor CF Lung Health
This study uses MRI scans to monitor lung health in teens and young adults with cystic fibrosis who are taking Trikafta. It aims to find better ways to track how the disease affects the lungs over time.
Cincinnati, OhioAges 12–21 - NCT06339424RecruitingPhase 2
Atezolizumab and Bevacizumab with radiation for liver cancer that can't be removed
This trial tests adding two immunotherapy and anti-angiogenesis drugs (atezolizumab and bevacizumab) to standard photon radiation for people with liver cancer that cannot be surgically removed. It aims to see if this combination can shrink tumors and improve outcomes.
Taoyuan City, TaiwanAges 18 years+ - NCT06339619RecruitingPhase 2
Combination immunotherapy for advanced esophageal cancer after prior treatment
This trial tests a combination of three drugs (adebrelimab, apatinib, and a chemotherapy pill) for people with advanced esophageal cancer whose previous immunotherapy treatment stopped working. The goal is to see if this new combination can help the immune system fight the cancer again.
Guangzhou, GuangdongAges 18–75 - NCT06339801Recruiting
Mucosal impedance test for GERD diagnosis
This study tests a new way to measure how your esophagus lining reacts to acid (called mucosal impedance) to help diagnose GERD. It's for people who still have symptoms even after taking standard medication for 8 weeks.
Buenos AiresAges 18–65 - NCT06340646Recruiting
Washington University cancer gene study
This study collects genetic information from people with certain cancers to learn more about cancer risks and outcomes. It may help researchers understand how genes affect cancer in different groups.
St Louis, MissouriAges 18 years+ - NCT06340620Recruiting
Comparing a new ultrasound tool to the standard scope
This study compares a new, possibly easier-to-use ultrasound tool (EndoSound Vision System) to the standard echoendoscope for looking at organs like the pancreas, bile duct, or lymph nodes. If you are already scheduled for an endoscopic ultrasound, you may be able to join.
Orlando, FloridaAges 18–100 - NCT06341296RecruitingPhase 2
Irinotecan liposomes for first-line advanced colorectal cancer
This trial tests a new type of chemotherapy (irinotecan liposomes) as a first treatment for metastatic colorectal cancer that has not been treated before. It focuses on patients with specific genetic changes (RAS or BRAF V600E mutation) or right-sided colon cancer, and looks at how well the drug works.
Sichuan, Sichuan, ChengduAges 18–85 - NCT06341270Recruiting
Electric acupressure for pain after liver surgery
This trial tests if a gentle electric stimulation on the skin (TEAS) can reduce pain and speed up recovery after liver surgery. The treatment is non-invasive and may be an alternative to pain medicines.
Chengdu, SichuanAges 18–80 - NCT06341595RecruitingPhase 2
Chemo, radiation and immunotherapy before surgery for stomach cancer with PALM
This trial tests combining chemotherapy, radiation, and an immunotherapy drug (sintilimab) before surgery for advanced stomach cancer that has spread to lymph nodes near the aorta (called PALM). The goal is to see if this approach can shrink the tumor enough to allow complete removal.
Nanjing, JiangsuAges 18–75 - NCT06343597Recruiting
Volume Outcome Relationships and Effects in Esophageal Cancer
This trial looks at how hospital experience (volume) affects outcomes for people with esophageal cancer. It aims to understand if hospitals that treat more cases get better results.
Richardson, TexasAges 18 years+ - NCT06342011Recruiting
Anti-inflammatory diet for inflammatory bowel disease
This trial tests whether an anti-inflammatory diet can help people with inflammatory bowel disease (IBD). Researchers want to see if this diet reduces inflammation and improves symptoms.

Personalized vaccine combined with immunotherapy and chemo after pancreatic cancer surgery
This trial tests a personalized neoantigen vaccine given along with an anti-PD1 drug (pembrolizumab) and chemotherapy after surgery for pancreatic cancer. The goal is to see if this combination can help prevent the cancer from coming back.

Immunotherapy combo for advanced MSI-H stomach/esophageal cancer
This trial tests a combination of immune checkpoint inhibitors (nivolumab, botensilimab, and balstilimab) plus chemotherapy for people with advanced stomach or esophageal cancer that has a specific genetic instability (MSI-H/dMMR) and expresses PD-L1. It may be an option for those who haven't had prior immunotherapy or chemotherapy for advanced disease.
