This study tests whether adding an immunotherapy drug (PD-1 antibody) to standard chemoradiation can improve outcomes for people with a rare type of rectal cancer called squamous cell carcinoma. About 20 adults with newly diagnosed, non-spread cancer will receive the combination.…

This phase 2 trial tests a powerful mix of short-course radiation, chemotherapy (mFOLFOX6), an immunotherapy (PD-1 antibody), and a targeted drug (cetuximab or bevacizumab, depending on genetic markers) in people with high-risk rectal cancer that is mismatch repair proficient (pM…

This Phase 3 trial tests whether adding immunotherapy and a targeted drug to short-course radiotherapy and chemotherapy improves outcomes for people with high-risk rectal cancer. About 204 participants will receive either the standard treatment or the intensified combo. The study…

This study compares a new treatment approach for high-risk rectal cancer: short-course radiation followed by immunotherapy (toripalimab) and chemotherapy (FOLFOX) versus the standard long-course chemoradiation. The goal is to see if the new approach leads to more complete tumor r…

This study is for people with a type of stomach cancer that is H. pylori-positive and can be removed with surgery. It compares standard chemotherapy before and after surgery to the same chemotherapy plus treatment to eliminate H. pylori bacteria. The goal is to see if adding the …

This study is looking at whether people with locally advanced colorectal cancer who have already received chemotherapy or radiation before surgery can safely skip additional chemotherapy afterward. The trial will compare a 'wait and watch' approach to standard adjuvant chemothera…

This study tests whether adding a low dose of upadacitinib (a JAK inhibitor) to a standard TNF inhibitor (like infliximab or adalimumab) works better than simply increasing the dose of the TNF inhibitor alone for people with moderate-to-severe Crohn's disease. About 312 adults wh…

This study tests whether adding a citrus flavonoid tablet (Aimailang) to standard chemotherapy (mFOLFOX) before surgery can shrink tumors more effectively in people with locally advanced rectal cancer that has a specific marker (YWHAB). About 236 participants will be randomly ass…

This study looks at whether a special liquid diet called exclusive enteral nutrition (EEN) can help adults with active Crohn's disease feel better and reduce inflammation. About 300 participants will use EEN as their main treatment for 12 weeks. Researchers will check remission r…

This study tests whether patients with a specific type of rectal cancer (dMMR/MSI-H) can safely avoid surgery after immunotherapy. After six rounds of a PD-1 inhibitor, those whose tumors completely disappear will be monitored closely instead of undergoing standard treatments. Th…

This phase 2 trial tests a PD-1 monoclonal antibody (immunotherapy) alone or combined with chemotherapy (mFOLFOX6) before surgery in people with multiple colorectal cancers. The goal is to shrink tumors and increase the chance of complete removal while preserving organs. The stud…

This study tests a sequential treatment for moderate to severe ulcerative colitis. First, patients take upadacitinib (a fast-acting pill) along with vedolizumab (a slow but safe infusion) for 8 weeks to quickly reduce inflammation. Then, they continue with vedolizumab alone for l…

This study is testing an interleukin-23 monoclonal antibody, a drug that blocks a key inflammatory protein, in 200 adults with moderate to severe Crohn's disease or ulcerative colitis. Participants receive the drug and are followed for 54 weeks to see if they can achieve remissio…

This phase II trial is testing whether a high-precision radiation technique called stereotactic body radiation therapy (SBRT) can help control locally recurrent rectal cancer that cannot be surgically removed. The study will enroll 40 adults aged 18-75 with unresectable tumors an…

This study watches how well IL-23 inhibitors work for adults with active Crohn's disease in everyday clinics. About 665 people will get treatment chosen by their doctor and be checked at 12 and 52 weeks. The main goal is to see how many reach remission (symptom-free) by week 12, …

This study tests whether combining targeted radiation (SBRT) with an immunotherapy drug (PD-1 antibody) can help people whose rectal cancer has returned and cannot be surgically removed. About 31 adults with a specific type of colorectal cancer will receive the treatment and be f…

This study looks at whether using two drugs together (upadacitinib and vedolizumab) works better than just one drug (upadacitinib alone) for people with moderate-to-severe ulcerative colitis, a chronic bowel disease. Researchers will review medical records from 150 adults across …

This study tests whether combining two drugs—upadacitinib and ustekinumab—works better than just increasing the dose of ustekinumab alone for people with Crohn's disease who didn't get enough help from standard treatment. About 214 adults with active Crohn's will be randomly assi…

This phase II trial is testing whether a new approach—using targeted radiation that spares lymph nodes, followed by chemotherapy and an immunotherapy drug—can improve outcomes for patients with a specific type of high-risk colon cancer. The study will enroll 52 adults whose tumor…

This phase II trial tests whether adding a special low-dose radiation therapy to standard chemotherapy and an immunotherapy drug can improve treatment for a type of colon cancer that usually doesn't respond well to immunotherapy alone. The study enrolls 38 adults with high-risk, …

This study tests whether giving anesthesia in carefully adjusted doses, rather than fixed amounts, can reduce dangerously low blood pressure in people aged 65 and older having laparoscopic abdominal surgery. The trial will enroll 500 participants and use two drugs, ciprofol and r…

This study tests whether a nerve block (superior hypogastric plexus block) can help people recover better after laparoscopic surgery for colorectal cancer. About 170 adults having this surgery will be randomly assigned to receive the nerve block or not. The main goal is to see if…

This study compares two surgical methods (Parks and Bacon) for ultra-low rectal cancer to see which one leads to better bowel function and quality of life a year after surgery. About 256 adults with rectal cancer will take part. The goal is to help doctors choose the best techniq…

This study tests whether megestrol acetate, a drug that boosts appetite, can help patients with locally advanced colorectal cancer avoid weight loss during chemotherapy. About 60 adults will receive either the drug or a placebo alongside their standard treatment. The goal is to s…

This study is testing whether an artificial intelligence (AI) system can analyze MRI scans to predict how well rectal cancer responds to chemotherapy and radiation before surgery. Researchers will enroll 1,700 adults with locally advanced rectal cancer. The goal is to help doctor…

This observational study looks at whether taking metformin before surgery affects nausea and vomiting after general anesthesia. Researchers will follow 909 adults who are already on metformin and compare them to those not taking it. The goal is to see if metformin changes how oft…

This study will follow 150 people with radiation rectal injury to see if different subtypes of the condition lead to different outcomes. Researchers will collect medical records, endoscopy images, and test results but will not change any treatments. The goal is to fill gaps in kn…

This study looks at whether a special type of MRI, called amide proton transfer-weighted imaging, can accurately predict if rectal cancer has completely disappeared after chemotherapy and radiation. Researchers will compare the MRI results with the actual tissue removed during su…

This study looks back at the medical records of 200 women with breast cancer to compare two types of breast-conserving surgery: one done with a robot and one done with an endoscope. The goal is to see which method leads to fewer complications, shorter surgery time, and better cos…

This study looks at gut bacteria in 300 people with colorectal cancer to see if certain bacteria are linked to cancer spread. Researchers will compare stool and tissue samples from patients whose cancer has spread versus those whose cancer has not. The goal is to find bacterial p…
