Financial help for newly diagnosed cancer patients
This study looks at whether getting help with financial issues (like insurance and costs) can reduce the money worries and problems that come with cancer treatment. It is for people newly diagnosed with breast, colorectal, or prostate cancer who haven't started treatment yet.

Asian Watch-and-Wait Study for Rectal Cancer
This study is for people with rectal cancer who have had treatment like radiation or chemo and their tumor has disappeared or nearly disappeared. Instead of surgery right away, doctors will closely monitor the cancer with regular check-ups to make sure it stays gone.

Chemo through liver artery with lipiodol for advanced liver cancer
This trial tests giving chemotherapy directly into the liver artery (HAIC) mixed with a special oil called lipiodol. It may help people with advanced liver cancer that cannot be treated with standard methods or who cannot tolerate them.
TaipeiAges 20 years+ - NCT06632886Recruiting
AI study to find cancers from your past CT scans
This study uses artificial intelligence to look at CT scans you've already had (without dye) to try and find signs of several types of cancer early. It may help find cancer sooner when it's easier to treat.

Virtual ileostomy vs. diverting ileostomy for rectal cancer surgery
This trial compares a virtual ileostomy (a system that monitors leaks without creating a temporary opening) to a traditional diverting ileostomy (a temporary bag) in people having rectal cancer surgery. The goal is to see if the virtual method is safer and avoids a second surgery.
ChongqingAges 18 years+ - NCT06633224Recruiting
Fatigue and biology in cancer patients getting chemoradiation
This study looks at why some people feel very tired during cancer treatment. Researchers will collect blood and stool samples to study how the body responds to chemotherapy and radiation.
San Francisco, CaliforniaAges 18 years+ - NCT06634160Recruiting
Fatty liver disease in people with high cholesterol
This study checks how common fatty liver disease is in people with a genetic form of high cholesterol. It may help researchers understand the link between these two conditions.
AngersAges 35 years+ - NCT06634875RecruitingPhase 2
Test of isunakinra alone or with pembrolizumab for colorectal cancer
This trial tests a new drug combination (isunakinra plus pembrolizumab) for people with a specific type of colorectal cancer (MSS, RAS-mutated) that has a high tumor mutational burden. It may help if other treatments have stopped working.
Los Angeles, CaliforniaAges 18 years+ - NCT06636032RecruitingPhase 1/Phase 2

This trial tests whether injecting donated stem cells into complex anal fistulas can help heal them in people with Crohn's disease. You may qualify if you have a fistula that hasn't improved with standard treatments.
ToulouseAges 18 years+ - NCT06636435RecruitingPhase 1
Study of CBA-1205 for advanced cancers including liver, melanoma, and pediatric cancer
This trial tests a new drug called CBA-1205 for people with advanced solid tumors, liver cancer, melanoma, or certain childhood cancers that have not responded to standard treatments. The drug targets a protein called DLK1 found on some cancer cells.
Kashiwa, ChibaAges 2 years+ - NCT06636513Recruiting
Testing SMT04 for irritable bowel syndrome
This trial tests a new treatment called SMT04 for people with irritable bowel syndrome (IBS), specifically the diarrhea or mixed types. It may help reduce symptoms like abdominal pain and changes in bowel habits.
Singapore, SingaporeAges 21–55 - NCT06636656RecruitingPhase 2
Testing a new drug for ulcerative colitis after other treatments failed
This study tests a new medication called BI 3032950 for people with ulcerative colitis who have already tried other advanced treatments (biologics or targeted therapies) that didn't work well enough or caused problems. The goal is to see if the new drug is safe and helps control inflammation in the colon.
Scottsdale, ArizonaAges 18–80 - NCT06637163RecruitingPhase 2
Study of benmelstobart plus chemo-radiation before surgery for esophageal cancer
This trial tests whether adding an immunotherapy drug (benmelstobart) to standard chemotherapy and radiation before surgery can help treat a certain type of esophageal cancer that can be surgically removed. The goal is to see if this combination is safe and works better than standard treatment alone.
Shantou, GuangdongAges 18 years+ - NCT06637215Recruiting
Day surgery for colorectal cancer
This study tests whether a same-day surgery approach for colorectal cancer is safe and effective. It uses small incisions and special pain management to help you recover faster at home with a caregiver nearby.
Shenyang, LiaoningAges 18–75 - NCT06637462Recruiting
Studying standard treatment response before rectal cancer surgery
This study looks at how rectal cancer responds to the usual chemotherapy and radiation given before surgery. It aims to learn if certain molecular features of your tumor can predict how well it responds to treatment.
Middletown, New JerseyAges 18 years+ - NCT06637631RecruitingPhase 2
Testing an oral pill for moderate to severe Crohn's disease
This study tests an experimental oral pill (SAR441566) for people with moderate to severe Crohn's disease. It aims to see if the drug can reduce inflammation and improve symptoms, especially for those who have not had success with other treatments.
