Short-course radiation plus chemo and immunotherapy for rectal cancer
This trial tests a treatment plan that uses a short course of radiation to the lymph nodes-sparing area, followed by chemotherapy and an immunotherapy drug (PD-1 inhibitor) for people with a specific type of mid or low rectal cancer (pMMR/MSS). The goal is to see if this approach can shrink the tumor and improve outcomes without needing extensive surgery.

Brain stimulation and probiotics for diarrhea-predominant IBS
This trial tests whether combining a type of brain stimulation (repetitive transcranial magnetic stimulation) with a probiotic tablet can help people with diarrhea-predominant irritable bowel syndrome. It aims to improve symptoms by targeting both the brain and the gut.
Suzhou, JiangsuAges 18–70 - NCT06960863Recruiting
Fibroscan to monitor immunotherapy in liver cancer
This study uses a special ultrasound (Fibroscan) to check how well immunotherapy is working for advanced liver cancer. It may help doctors see if the treatment is effective without needing a biopsy.
Tanta, GharbyeaAges 18 years+ - NCT06960954Recruiting
Testing a blood marker for liver cancer blood clots
This study looks at whether a substance in the blood called PIVKA-II can predict blood clots in the main vein of the liver (portal vein) in people with liver cancer. Participating could help doctors better identify who might develop this complication.
Tanta, GharbyeaAges 18 years+ - NCT06961149Recruiting
Comparing light vs dye spray for colon polyp detection
This study compares two methods used during colonoscopy to help find polyps in the colon. It tests whether a special light technique (linked-color imaging) or a dye spray (indigo carmine) works better for spotting adenomas, which are growths that can turn into cancer. If you are at higher risk for colorectal adenomas, this trial may help improve detection.
Jinan, ShandongAges 45–85 - NCT06961526Recruiting
Preventing varices bleeding in liver cancer patients on immunotherapy
This trial tests if preventing esophageal varices (swollen veins in the food pipe) can reduce bleeding risk in people with advanced liver cancer who are receiving a combination of two drugs (atezolizumab and bevacizumab). It may help those with good liver function and no high-risk varices at the start.
Tanta, GharbyeaAges 18 years+ - NCT06961617RecruitingPhase 1
Immune cell therapy for advanced hepatitis B-related liver cancer
This trial tests a new immune cell therapy (LioCyx-M) for people with advanced liver cancer caused by hepatitis B. It uses specially designed T cells (a type of immune cell) that target the hepatitis B virus and may help fight the cancer.
BeijingAges 18–70 - NCT06962020Recruiting
Choosing the best first biologic for moderate to severe colitis
This study compares two first-line biologic drugs for moderate to severe ulcerative colitis to see which works better and why. The goal is to help find the best biologic treatment for each patient.
Shanxi, Xi'anAges 18–70 - NCT06962293Recruiting
Magnetic tool for removing early stomach or colon polyps
This trial uses a special magnetic device to help doctors remove early-stage growths in the stomach or colon during a standard procedure called endoscopic submucosal dissection (ESD). The magnet pulls the tissue into a better position, which may make the removal safer and more effective.
Hong KongAges 18–85 - NCT06962267RecruitingPhase 2
Study of TQB2916 with chemo for advanced pancreatic cancer
This trial tests a new drug (TQB2916) combined with standard chemotherapy (gemcitabine and nab-paclitaxel) as a first treatment for metastatic pancreatic cancer. It aims to see if the combination works better than chemo alone.
Beijing, Beijing MunicipalityAges 18–75 - NCT06962670Recruiting
Cancer risk study using digital and molecular markers
This study uses a smartphone app and biological markers to predict cancer risk. It is testing whether digital and molecular data can help identify cancer earlier, especially in women with a history of certain cancers.

Ultrasound to measure blood loss after C-section
This study tests whether a quick ultrasound after a C-section can better estimate blood loss than the usual visual method. If you are a woman who had a C-section, you may be eligible to help improve care for future mothers.
Nazareth, NorthAges 18–50 - NCT06964438Recruiting
Post-surgery electrical muscle stimulation study for colorectal or stomach cancer
