Mobile, AlabamaAges 45–84 - NCT07623174Recruiting
Fruquintinib for Advanced Colorectal Cancer in Poland
This study follows adults in Poland who are receiving fruquintinib, a targeted cancer medicine, for advanced colorectal cancer that has spread. You would be enrolled if your doctor is already planning to give you fruquintinib as a later-line treatment after other therapies have stopped working.

Combination therapy for advanced colorectal cancer
This trial tests a combination of three drugs (fruquintinib, chidamide, and sintilimab) for people with a specific type of metastatic colorectal cancer that has not responded to at least two prior treatments. It aims to see if this combination is safe and effective.
BeijingAges 18–75 - NCT06697067Recruiting
Comparing two ways to close belly incisions after emergency surgery
This study compares two different stitch techniques to close the belly wall after emergency surgery for a hole in the stomach or intestines. It aims to see which method leads to better healing and fewer wound problems.
Lahore, Punjab ProvinceAges 18–60 - NCT07622797RecruitingPhase 2
Immunotherapy with chemotherapy and radiation for esophageal cancer
This trial tests a new immunotherapy drug (camrelizumab) combined with standard chemotherapy and radiation to treat advanced esophageal cancer while avoiding surgery if possible. The goal is to shrink the tumor and help you keep your esophagus working.
Luoyang, HenanAges 18 years+ - NCT07620665Recruiting
Pain Relief Medicine for Gallbladder Removal Surgery
This trial tests a new pain medication called opiranserin for patients having minimally invasive gallbladder surgery (a small-cut procedure). The goal is to see if it safely reduces pain after surgery.
SeoulAges 19 years+ - NCT07626463Recruiting
Local anesthetic injection to reduce pain after laparoscopic surgery
This trial tests whether injecting a local anesthetic (numbing medicine) and a steroid around the surgical area before surgery reduces pain after laparoscopic procedures like gallbladder, appendix, or hernia repair. The goal is to help patients recover more comfortably with potentially less pain medication needed.
Beijing, Beijing MunicipalityAges 18–64 - NCT07626606Recruiting
Gut Health and Rotavirus Vaccine Response in Adults
This study examines how the health of your digestive system affects how well your body responds to an oral rotavirus vaccine (a vaccine given by mouth to protect against rotavirus infection). You'll have two endoscopy procedures—a camera test to look inside your digestive tract—and provide samples to help researchers understand this connection.
Lusaka, Lusaka ProvinceAges 18–50 - NCT07627217Recruiting
Understanding MNGIE disease progression and natural history
This study collects information from patients with MNGIE (a rare genetic condition affecting how cells break down certain molecules) to better understand how the disease develops and progresses over time. By learning more about your experience, researchers hope to develop better treatments.
CambridgeAges Any age - NCT07623265Recruiting
Understanding Immunotherapy Response in Liver Cancer
This study collects tumor samples and medical information from patients with liver cancer to understand why some patients respond better to immunotherapy (immune-boosting drugs) than others. The goal is to improve treatment selection and outcomes for future patients.
AntwerpAges 18 years+ - NCT07621783Recruiting
Blood protein levels and bowel disease activity in IBD
This study measures a blood protein called LRG and compares it to how active your inflammatory bowel disease (IBD) is during a planned scope procedure. The goal is to see if this blood test could help doctors assess disease activity more easily in the future.
BonheidenAges 16 years+ - NCT07622771RecruitingPhase 2
Radiation, chemotherapy, and immunotherapy for advanced rectal cancer
This trial tests a combination of radiation therapy, a chemotherapy drug called NALIRIFOX, and an immunotherapy drug called adebrelimab for rectal cancer that has grown into nearby tissue or lymph nodes. The goal is to see if this combination helps shrink the tumor before surgery and improves outcomes.
Guangzhou, GuangdongAges 18–75 - NCT07625189Recruiting
Registry tracking EUS-guided ablation for pancreatic and digestive lesions
This registry collects information about patients receiving a specialized procedure called EUS-guided ablation—using heat to destroy abnormal growths in the pancreas and digestive tract. By tracking your care, researchers aim to better understand how effective and safe this treatment is.

It is for people who have not yet started treatment for their metastatic disease and have a BMI of 25 or higher.
Tucson, ArizonaAges 18–99 - NCT07621757Enrolling by invitation
Genetic Risk Testing for Colorectal Cancer Screening
This study looks at how genetic risk information can help decide who needs colorectal cancer screening and when. Researchers want to see if testing for genetic risk factors improves screening decisions for people who haven't had a colonoscopy before.

Spinal Pain Relief During Hiatal Hernia Surgery
This trial tests whether injecting pain medication directly into the spinal fluid during a minimally invasive stomach surgery (called fundoplication) helps reduce pain after the operation. Fundoplication is used to treat severe acid reflux.
Karlstad, Värmland CountyAges 18 years+ - NCT07628205Enrolling by invitationPhase 2
Botulinum Toxin to Help Close Large Belly Wall Hernias
This study tests whether injecting botulinum toxin (Botox) before surgery can help close large holes in the belly wall by relaxing the muscles and making it easier to bring the edges together. This might reduce complications and improve healing after surgery.
