Tegavivint for advanced colorectal cancer after other treatments
This early-phase trial tests an experimental drug called tegavivint for people with advanced colorectal cancer who have already tried several standard treatments. It aims to see if the drug can shrink or slow the growth of tumors.

MoscowAges 18–70 - NCT07467980Recruiting
Measuring oxygen in the colon during bowel surgery
This study tests a new way to measure oxygen levels inside the colon during surgery, right after the surgeon reconnects the bowel. It may help doctors see if the new connection is healing well.

PULSAR with Fecal Transplant for Advanced Liver Cancer
This trial tests a new combination treatment (PULSAR plus fecal microbiota transplant) for people with advanced liver cancer that stopped responding to initial therapy. It aims to see if this approach can help control the cancer again.
Chengdu, SichuanAges 18–75 - NCT07464600Recruiting
CRP testing to predict leaks after colon surgery
This trial checks if a simple blood test for CRP (a marker of inflammation) after colorectal surgery can help predict if a patient might develop a leak where the bowel is reconnected. If you are having planned colon or rectal surgery, this study might be for you.
AmiensAges 18 years+ - NCT07464756RecruitingPhase 2
Study of SHR-1701 and apatinib with chemo before stomach cancer surgery
This trial tests whether adding SHR-1701 (an immunotherapy) with or without apatinib (a targeted therapy) to standard chemotherapy before surgery can help treat gastric cancer. It is for people with stomach or gastroesophageal junction cancer that has spread to nearby lymph nodes but is still removable.
Nanjing, JiangsuAges 18 years+ - NCT07464470Recruiting
Comparing stomach cancer and brain metastasis genetics
This trial studies stomach and esophageal cancers that spread to the brain. It compares the genetic makeup of the original tumor to the brain metastasis, which may help find better treatments.
MoscowAges 18 years+ - NCT07464392Recruiting
Fecal transplant to prevent infections in severe pancreatitis
This trial tests whether a fecal microbiota transplant (FMT) can help prevent infections in people with moderately severe or severe acute pancreatitis. You may qualify if you are between 18 and 75, have had pancreatitis for 15 to 21 days, and already have a feeding tube in place.
Fuzhou, FujianAges 18–75 - NCT07469319Recruiting
Liver cancer screening for people with cirrhosis
This study tests whether offering an ultrasound and a blood test (alpha-fetoprotein) every 6 months can help find liver cancer early in people with cirrhosis (scarred liver) caused by conditions other than hepatitis B or C. The goal is to reduce deaths from liver cancer in this group.
Aarhus, Central JutlandAges 40–79 - NCT07470502Recruiting
Study of infliximab for children and teens with IBD
This trial is looking at children and teenagers with Crohn's disease or ulcerative colitis who are starting a biologic medicine called infliximab. It aims to learn more about how this treatment works in young patients.
Florence, ItalyAges 3–18 - NCT07469709Recruiting
Cancer risk study using genetics and monitoring
This study looks at genetic and other factors in people with certain cancers to better understand personal cancer risks and improve monitoring. It may help find ways to detect changes earlier.
Candiolo, TurinAges 18 years+ - NCT07470658Enrolling by invitation
Surveillance after positive FIT and normal colonoscopy
This trial studies the best way to follow up with people who had a positive FIT stool test (high blood level) but a normal colonoscopy. It aims to find the right schedule for future screening to catch any problems early.
TaipeiAges 45–74 - NCT07466238Recruiting
Chemo into the liver plus IV chemo for bile duct cancer
This trial is testing a treatment plan that first delivers chemotherapy directly into the liver (through a thin tube) along with standard IV chemotherapy. The goal is to shrink the tumor enough to allow for surgery or less aggressive treatment later. It is for people with bile duct or gallbladder cancer that has not spread far.
BeijingAges 18–80 - NCT07465614Recruiting
Nerve stimulation study for children with cyclic vomiting syndrome
This study tests whether a gentle nerve stimulation device placed on the ear can reduce vomiting episodes in children with cyclic vomiting syndrome (CVS). It aims to find a safe, non-drug option for managing symptoms.
Milwaukee, WisconsinAges 5–18 - NCT07468630RecruitingPhase 2
Tocilizumab plus chemoimmunotherapy for advanced colon cancer
This study tests a new combination of medications for people with locally advanced colon cancer. It aims to see if adding tocilizumab to standard chemo-immunotherapy can help shrink or control the tumor.
Chongqing, Chongqing MunicipalityAges 18–80 - NCT07464626Recruiting
Art therapy for anxiety and sleep in colorectal cancer patients
This study compares virtual and in-person art therapy to help reduce anxiety, improve psychological well-being, and enhance sleep quality for people with colorectal cancer who are receiving chemotherapy.
Izmir, BalçovaAges 18 years+ - NCT06791083RecruitingPhase 2
Envafolimab, Fruquintinib, and chemo before gastric cancer surgery
This trial tests a combination of two targeted drugs (Envafolimab and Fruquintinib) plus chemotherapy given before surgery for certain types of stomach cancer. The goal is to see if this approach can shrink the tumor and improve outcomes.
Fuzhou, FujianAges 18–75 - NCT06791148RecruitingPhase 2
Low-dose radiation plus chemo and immunotherapy for advanced stomach cancer
This trial tests a combination of low-dose radiation, chemotherapy, and an immunotherapy drug (AK112) for people with advanced stomach or gastroesophageal junction cancer that has progressed after first-line treatment. The goal is to see if this combination can help shrink tumors or slow the cancer's growth.
Nanjing, JiangsuAges 18–75 - NCT06792604Recruiting
Methylation test for anal cancer screening
This study is testing a new way to screen for anal cancer by looking at DNA methylation in cells collected from the anus. It may help people at higher risk for anal cancer find out earlier if they need further tests.
