BelfastAges 18 years+ - NCT05768503RecruitingPhase 3
Test new drugs after colorectal cancer chemotherapy
This Phase 3 trial compares a new treatment combination (chidamide plus sintilimab plus bevacizumab) versus the standard second-line chemotherapy (FOLFIRI plus bevacizumab) for advanced colorectal cancer that is microsatellite stable/low. It aims to see which treatment works better and is safer for people whose cancer grew after first-line oxaliplatin-based therapy.
Hefei, AnhuiAges 18–75 - NCT05768932RecruitingPhase 1
Study drug for advanced cancers or relapsed AML
This Phase 1 trial tests BAL0891, a new study treatment, in people with advanced solid tumors that have run out of treatment options, or in relapsed/refractory acute myeloid leukemia (AML). The goal is to find a safe dose and see how well it may work in these hard-to-treat cancers.
New Haven, ConnecticutAges 18 years+ - NCT05769816RecruitingPhase 2
Combination treatment aimed to cure chronic hepatitis B
This Phase 2 study tests a combination therapy to help people with chronic hepatitis B reach a “functional cure,” meaning the hepatitis B surface antigen (HBsAg) is lost for a sustained period. If you qualify, you’ll be closely monitored to see how well the treatment works and whether it’s safe for you.
Chongqing, Chongqing MunicipalityAges 18–70 - NCT05770102RecruitingPhase 2/Phase 3
Atezolizumab for cancers with high mutation or immune markers
This trial tests atezolizumab, a cancer immunotherapy, for people whose tumors have high mutation levels (TMB), or are “MSI-high,” or have CMMRD. It may help shrink cancer or slow its growth by boosting the immune system’s ability to recognize the tumor.
BelfastAges Any age - NCT05771181RecruitingPhase 2
Test vitamin E plus two cancer drugs for metastatic colon cancer
This trial tests whether adding vitamin E to two cancer medicines (fruityquintinib and tislelizumab) can work better in people with metastatic colorectal cancer that is mismatch-repair stable (MSS). It may help if your cancer has grown despite standard treatment, and you can meet the study’s safety and blood/organ requirements.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05771402RecruitingPhase 2
Combination treatment aimed at clearing hepatitis B long-term
This Phase 2 study tests a combination treatment to help people with chronic hepatitis B stop having detectable hepatitis B surface antigen (called HBsAg). If successful, it may move you closer to a “functional cure,” meaning lower ongoing virus activity over time.
Chongqing, Chongqing MunicipalityAges 18–70 - NCT05771597Recruiting
Home biofeedback to improve bowel and bladder control
This study tests whether doing guided “biofeedback” exercises at home can improve problems with constipation/blocked feeling, fecal leaks, and/or urine leaks. It focuses on retraining the muscles used for toileting to help you empty more normally and have fewer accidents.
Augusta, GeorgiaAges 18 years+ - NCT05772481Recruiting
PET-MRI scan test for rectal cancer after pre-surgery treatment
This study looks at whether a special scan called PET-MRI can better show how rectal cancer responds to treatment given before surgery. If it works well, it could help doctors plan the right next steps after chemoradiotherapy.
StrasbourgAges 18–75 - NCT05772923Recruiting
Testing rectal cancer organ-preservation after radiation
This trial compares two ways to preserve the rectum/avoid major surgery after radiation: a focused contact x-ray treatment versus waiting longer and then removing only a small area if needed. It may help some people keep more normal bowel function while still controlling the cancer.
Nijmegen, GelderlandAges 18 years+ - NCT05773144Recruiting
Exercise program during chemotherapy for colon cancer recovery
This trial tests an aerobic exercise plan during chemotherapy for people with stage II or III colon cancer. It compares different exercise approaches to see if exercise can be done safely and may improve how you tolerate treatment and recovery.
Oakland, CaliforniaAges 18 years+ - NCT05775146RecruitingPhase 2
Radiation to liver metastases after colon cancer treatment
This trial studies giving targeted high-dose radiation (SBRT) to liver metastases from colorectal cancer after initial treatment, with the goal of improving long-term control or cure. It may help people who have a limited number of liver spots that doctors think can be treated safely and effectively.
Edmonton, AlbertaAges 18 years+ - NCT05775419Recruiting
Chemo and radiation, with or without extra chemo after
This trial compares standard chemo plus radiation versus the same treatment plus extra “consolidation” chemo afterward. It’s for people with a type of esophageal cancer that can’t be removed with surgery, to see if the added treatment works better and is still safe.
Nanjing, JiangsuAges 18–70 - NCT05775939Recruiting
PET/CT scan study to track heart damage from cancer radiation
This study uses a special scan (PET/CT) to look for early heart (cardiac) injury caused by radiation treatment for lung or esophageal cancer. If you may be at higher heart risk from your planned radiation dose, the scan may help researchers better measure that damage over time.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05776524RecruitingPhase 2
Radiofrequency heat treatment for pancreas cancer spread to other organs
This Phase 2 trial tests whether a device that delivers carefully timed “radiofrequency heat” through the body can slow or control metastatic (spread) pancreatic cancer. You may qualify if you have newly diagnosed metastatic pancreatic cancer and can meet safety and blood-test requirements.
Winston-Salem, North CarolinaAges 18 years+ - NCT05776914RecruitingPhase 2
Fecal transplant to treat moderate to severe IBS symptoms
This trial tests whether putting stool (fecal microbiota) from a donor into your bowel can improve symptoms in people with IBS who are not IBS-C. It may help by changing the gut bacteria that can influence IBS symptoms.
Rochester, MinnesotaAges 18–70 - NCT05779761Recruiting
Brief coping exercises for high distress and worry
