Camrelizumab plus chemoradiotherapy for advanced esophageal cancer
This study tests whether adding camrelizumab (an immune treatment) to standard chemoradiotherapy can control advanced esophageal squamous cell cancer. It is meant for people who have not had any prior whole-course cancer medicines for this cancer stage.
FuzhouAges 18–75 - NCT06095466Recruiting
Heart check with ultrasound in severe liver disease
This study tests if a simple bedside heart ultrasound (echocardiogram) and blood tests can spot early heart problems in people with severe liver disease (cirrhosis) who are in the intensive care unit. It may help doctors better understand and manage heart complications in cirrhosis.
Sector-12, ChandigarhAges 18–65 - NCT05985109RecruitingPhase 2
KN 046 plus regorafenib for advanced colorectal cancer
This trial tests a combination of two drugs, KN 046 and regorafenib, in people with a type of advanced colorectal cancer that has not responded to previous treatments. The goal is to see if this combination can help shrink or control the tumor.
BeijingAges 18 years+ - NCT05551416Recruiting
Study to detect and prevent early stomach cancer
This study looks for early warning changes in the stomach and aims to improve early detection and prevention. Depending on your situation, you may be grouped as having stomach symptoms, early lesions that might be removed, already-diagnosed stomach cancer, or a comparison group without stomach problems.
Palma de Mallorca, Balearic IslandsAges 18 years+ - NCT05918367Recruiting
Registry for surgery to fix pelvic organ prolapse
This is a patient registry study for people having a laparoscopic or robotic operation called ventral mesh rectopexy to treat posterior pelvic organ prolapse. It mainly collects information through questionnaires to better understand outcomes and care, rather than testing a new drug.
BrusselsAges 18 years+ - NCT06102772Recruiting
Combination immunotherapy and targeted therapy for advanced gastric cancer
This trial tests a combination of three drugs—adebrelimab (an immunotherapy), fruquintinib (a targeted therapy to cut off blood supply to the tumor), and a chemotherapy (paclitaxel or albumin-bound paclitaxel)—in people with advanced stomach/gastric cancer whose disease has worsened after one prior chemotherapy. The goal is to see if this new mix can help control the cancer.
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT06102785Recruiting
Fruquintinib plus TAS102 for advanced stomach cancer
This trial tests a combination of two drugs, fruquintinib and TAS102, for people with advanced stomach cancer that has stopped responding to at least one prior chemotherapy. The goal is to see if this new combination can help shrink tumors or slow the cancer's growth.
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT06102759Recruiting
Study of adebrelimab and fruquintinib plus chemo for advanced stomach cancer after PD-1 failure
This trial tests a combination of two targeted drugs (adebrelimab and fruquintinib) plus chemotherapy (paclitaxel or albumin-bound paclitaxel) for people with advanced gastric or gastroesophageal junction cancer whose disease progressed after prior PD-1 antibody treatment. The goal is to see if this new combination can help when standard options have stopped working.
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT05444478Recruiting
Microwave ablation plus lenvatinib for recurrent liver cancer
This trial tests whether combining heat treatment to kill liver tumors (microwave ablation) with the medicine lenvatinib can better control recurrent hepatocellular carcinoma (HCC). It may help shrink tumors or slow growth for people whose cancer has come back but who have limited tumor burden.
Changsha, HunanAges 18–75 - NCT06104241RecruitingEarly Phase 1
Cell therapy for advanced digestive cancers
This trial tests a new cell therapy called BGT007 for people with advanced cancers of the digestive system (esophagus, stomach, pancreas, or colon) that have not responded to standard treatments. The therapy uses your own immune cells, modified to target a protein on your cancer cells.
Xuzhou, JangSuAges 18–70 - NCT06104215RecruitingEarly Phase 1
BGT007H cells for advanced digestive cancer
This trial tests a new cell therapy called BGT007H for people with advanced digestive tract cancers (esophagus, stomach, pancreas, or colon) that have not responded to or stopped working after at least two prior treatments. The goal is to see if this therapy can help shrink tumors or slow the disease.

BerlinAges 18 years+ - NCT03125343Recruiting
Watch-and-wait after rectal cancer treatment for select patients
This study looks at whether some people with rectal cancer can safely avoid immediate surgery after (chemo)radiation, instead closely monitoring their response. It may help some patients reduce treatment burden if the cancer fully responds.
GothenburgAges 18 years+ - NCT05494060RecruitingPhase 2
Adjuvant chemo plus immunotherapy for ctDNA-positive stomach cancer
This trial tests whether adding an anti-cancer immune treatment and another targeted drug to standard chemotherapy after surgery can lower the chance of cancer coming back. It is for people whose blood test (ctDNA) shows leftover cancer-related DNA after surgery.
Nanjing, JiangsuAges 18–75 - NCT03932461Recruiting
Wound suction vs immediate re-operation for severe bowel infection
This trial compares two ways of treating the abdomen after emergency surgery when there is severe contamination from a bowel perforation causing widespread peritonitis. It may help find the safest approach to control infection and promote healing.
