Los Angeles, CaliforniaAges 18 years+ - NCT05745857RecruitingPhase 2
Scan for early esophagus cancer using infused antibody dyes
This Phase 2 study uses special drug dyes (bevacizumab and cetuximab, each tagged for imaging) during an esophagus scope to help doctors find very early abnormal cells, like low- or high-grade pre-cancer and superficial cancer. If you qualify, the goal is earlier detection and better targeting during diagnosis and treatment.
Groningen, Provincie GroningenAges 18 years+ - NCT05746897RecruitingPhase 1
First-in-human test of an anti-PVRIG drug for advanced cancers
This early-phase study tests NM1F (an anti-PVRIG antibody) in people with advanced solid tumors to see if it’s safe and whether it may work. It also includes pembrolizumab (a PD-1 “checkpoint” medicine), aiming to boost the immune system against the cancer.
Dallas, TexasAges 18 years+ - NCT05748145RecruitingPhase 2
Metronidazole before colon cancer surgery to reduce recurrence risk
This Phase 2 study tests whether taking metronidazole, an antibiotic, before surgery for colorectal cancer can improve outcomes. Participants take it before their planned operation, and doctors study the cancer tissue and related markers to see if it helps.
Bellinzona, Canton TicinoAges 18 years+ - NCT05749822RecruitingPhase 2/Phase 3
Fenofibrate for primary biliary cholangitis with stable cirrhosis
This trial studies whether fenofibrate (a cholesterol medicine) can improve outcomes in people with primary biliary cholangitis (PBC) who already take ursodeoxycholic acid (UDCA) but still have abnormal liver blood tests. It specifically looks at people with “compensated” (stable) cirrhosis—meaning the liver disease is present but not causing severe complications right now.
Beijing, Beijing MunicipalityAges 18–75 - NCT05750498Recruiting
Study to improve outcomes in autoimmune liver disease
This trial tests approaches to improve health outcomes for people with autoimmune liver diseases. It includes specific autoimmune conditions affecting the liver and bile ducts, and it may help your care team learn what works best for these illnesses.
Palo Alto, CaliforniaAges Any age - NCT05751733Recruiting
Apatinib versus standard drug for advanced GIST after imatinib
This trial studies whether apatinib works better than the usual second-line targeted tablet for advanced gastrointestinal stromal tumor (GIST) after imatinib (or avatinib) no longer works. It may help people whose cancer has grown despite treatment or who couldn’t tolerate it.
Changsha, HunanAges 18 years+ - NCT05751343RecruitingPhase 2
Test atezolizumab and bevacizumab with liver cancer procedures
This Phase 2 trial tests whether atezolizumab plus bevacizumab, given along with liver cancer treatment procedures (TACE/HAIC), can help people with advanced liver cancer that cannot be removed by surgery. It mainly looks at whether these medicines can control the cancer more effectively and safely.
Guangzhou, GuangdongAges 18–75 - NCT05751967RecruitingPhase 3
Fenofibrate plus ursodeoxycholic acid for primary biliary cholangitis
This trial tests whether adding fenofibrate to ursodeoxycholic acid (UDCA) can improve liver test results in people with primary biliary cholangitis (PBC) who did not respond enough to UDCA alone. It aims to see if the combination works better and is safe for adults with persistent, abnormal liver markers.
Lanzhou, GansuAges 18–75 - NCT05752071Recruiting
Stomach stimulation to help bowel recovery after major surgery
This trial tests a stomach (gastrointestinal) stimulation approach to help your bowels start working again after extensive surgery, which may cause a temporary problem called postoperative ileus. If it helps, it could mean faster recovery and less time with bowel-related complications.
AarhusAges 18 years+ - NCT05752136RecruitingPhase 3
Pre-surgery radiation plus immunotherapy and chemo for rectal cancer
This trial tests whether a short course of radiation before surgery, combined with the immunotherapy drug envafolimab and the chemo regimen CAPEOX, works better for shrinking locally advanced rectal cancer. It is aimed at people whose tumor is not “MMR-deficient” (it is pMMR/MSS), and it asks participants to be able to return for repeated checkups and treatments.
Hangzhou, ZhejiangAges 18 years+ - NCT05753748Recruiting
Compare watchful waiting vs endoscopy treatment for Barrett’s with low-grade dysplasia
This trial compares two approaches for people with Barrett’s esophagus and low-grade dysplasia: regular monitoring versus treatment done through an endoscopy. It aims to see which approach is safer and better at preventing progression to more serious changes in the esophagus.
Los Angeles, CaliforniaAges 18–89 - NCT05754190Recruiting

Study drug mix for unresectable gallbladder cancer
This Phase 2 trial tests a combination of cancer medicines (gemcitabine plus albumin-paclitaxel) along with immune therapy (sintilimab) and a blood-vessel–targeting drug (bevacizumab). It’s for people with gallbladder cancer that can’t be removed by surgery, to see if the treatment controls the cancer and improves outcomes.
ShanghaiAges 18–75 - NCT05760391Recruiting
Check anti-PD-1 therapy plus radiation for advanced esophageal cancer
This trial studies whether adding an anti-PD-1 immunotherapy (with chemotherapy) together with radiation can help people with advanced esophageal squamous cell cancer. It’s for cases where surgery or standard definitive chemoradiation can’t be done, or the cancer has spread to distant sites.
ShanghaiAges 18–80 - NCT05763277Recruiting
Predicting early response to atezolizumab plus bevacizumab
