Charlotte, North CarolinaAges 40–49 - NCT07302347RecruitingPhase 1/Phase 2
Study of pembrolizumab for different cancers in Japan
This trial tests a drug called pembrolizumab (Keytruda) to see if it helps people with several types of cancer, including relapsed or refractory lymphoma, melanoma, MSI-high or TMB-high solid tumors, and Merkel cell carcinoma. The goal is to understand if this immunotherapy can shrink or control the cancer.
Nagoya, Aichi-kenAges 6 months+ - NCT04937283Recruiting

Surgery trial for early-stage cervical cancer with lymph vessel invasion
This trial studies whether a specific type of surgery (done through the abdomen or with keyhole surgery) is the right treatment for certain early cervical cancers. It aims to see how well these surgeries work when cancer hasn’t spread to lymph nodes.
ShanghaiAges 21–70 - NCT04935853Recruiting
Study of markers that predict bile duct cancer treatment response
This study looks at lab markers (including genetic tests) to predict how people with bile duct cancer respond to treatment. Your answers and samples may help doctors personalize care for bile duct cancer in the future.
AmiensAges 18 years+ - NCT04935684RecruitingPhase 2
Fecal transplant after bone marrow transplant to improve gut health
This Phase 2 study tests whether a fecal microbiota transplant (a processed transplant of gut bacteria) after an allogeneic bone marrow transplant is safe and helpful. Participants may benefit by improving recovery in the gut microbiome during the post-transplant period.
AmiensAges 18 years+ - NCT04936581Recruiting
Quality of life after rectal cancer surgery
This study looks at patient-reported outcomes—how you feel and function—after surgery for rectal cancer. It may help doctors better understand recovery and well-being after different surgical approaches and treatments.
MadridAges 18–100 - NCT04937309Recruiting
Vagus nerve stimulation for nausea from chemo
This trial tests a non-invasive device that stimulates a nerve in your ear to help prevent nausea caused by chemotherapy. It is for people with breast cancer who are about to start a specific type of chemo (anthracycline and cyclophosphamide).
BloisAges 18 years+ - NCT04939051RecruitingPhase 2
Obeticholic acid to prevent Barrett’s esophagus worsening
This Phase 2 trial tests whether obeticholic acid (a medicine) can help stop Barrett’s esophagus from getting worse. You must already be taking acid-suppressing medicine and have non-cancer Barrett’s changes, and the study checks safety and whether the lining improves or stays stable.
Kansas City, KansasAges 18 years+ - NCT04937647Recruiting
Using AI during endoscopy to evaluate stomach and bowel changes
This study looks at how well a computer “AI” system can help doctors spot stomach and bowel abnormalities during endoscopy (camera tests of the gut). If you’re having a gastroscopy or colonoscopy for symptoms or follow-up care, this could improve how findings are recognized.
Portsmouth, HampshireAges 18 years+ - NCT04938804Recruiting
One-time lung cancer screening with a low-dose chest CT
This study tests whether a one-time, low-dose chest CT scan can help find lung cancer early in certain people. You may be invited because of your age and location, and because you have not had recent related testing or symptoms.
Guangzhou, GuangdongAges 40–74 - NCT04939831Recruiting
Surgery study for certain stages of cervical cancer
This trial looks at two surgical approaches to remove the cervix in people with specific early-to-mid stage cervical cancer. It aims to see which approach is safer and/or works better for cancer control based on your cancer stage and scan results.
Shanghai, Shanghai MunicipalityAges 21–70 - NCT04941274RecruitingPhase 1/Phase 2
Abemaciclib for Kaposi sarcoma in people with or without HIV
This Phase 1/2 study tests the medicine abemaciclib to shrink Kaposi sarcoma (KS) lesions and control the disease. It includes both people with HIV and people without HIV, and may help when KS has not responded well to prior treatment or when certain KS stages are present.
Bethesda, MarylandAges 18–99 - NCT04941716RecruitingPhase 2
Acalabrutinib plus venetoclax for hard-to-treat CLL/SLL
This Phase 2 trial studies whether combining acalabrutinib and venetoclax can shrink or control chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) that has come back or did not respond to prior treatment. It may help by attacking the cancer using two different medicines together.
Seattle, WashingtonAges 18 years+ - NCT04943848RecruitingPhase 1
Vaccine plus immune treatment for newly diagnosed brain stem tumors
This early-phase trial tests a customized vaccine (made from your tumor’s cell parts) along with an immune “checkpoint blocker” medicine. It’s for newly diagnosed DIPG/DMG to see if this combination is safe and can help control the cancer.
Orange, CaliforniaAges 1–18 - NCT04943484Recruiting
ICG camera dye test during surgery for advanced stomach cancer
This trial tests whether an “ICG” dye and special camera can help surgeons see cancer more clearly during surgery for advanced stomach cancer. It may help improve how safely and accurately surgeons remove the tumor and nearby lymph nodes.
Milan, ItaliaAges 18 years+ - NCT04944563Recruiting
Segmentectomy vs lobectomy for small middle-lung lung cancer
This trial compares two types of lung surgery for certain small lung cancers in the middle part of the lung: removing a segment (segmentectomy) versus removing a whole lobe (lobectomy). It aims to see which surgery works better while balancing cancer control and lung function.
Nanjing, JiangsuAges 18–75 - NCT04944030Recruiting
Study collects health data for metastatic lung cancer patients
This study collects medical information and test results from people with lung cancer that has spread (or cannot be cured with local treatment). It does not test a new drug; it helps researchers better understand patients’ health and care needs over time.
AngersAges 18 years+ - NCT04943913RecruitingEarly Phase 1
TIL cell therapy for brain glioma after standard treatment fails
This early-stage study tests a treatment made from your tumor’s immune cells (TILs) to help shrink brain glioma. You may be considered if your glioma is back or has spread and standard options are no longer working (or don’t exist).
Suzhou, JiangsuAges 18–75 - NCT04944914RecruitingPhase 3
Camrelizumab with targeted radiation for limited nasopharyngeal cancer spread
This trial tests whether combining camrelizumab (an immune medicine) with stereotactic body radiotherapy (high-precision radiation) works better than camrelizumab alone. It’s for people whose nasopharyngeal cancer has spread to a small number of spots in the body and may help control those metastases longer.
Guangzhou, GuangdongAges 18–70 - NCT04945148RecruitingPhase 2
Metformin plus radiation and chemo for glioblastoma subtype
This Phase 2 study tests whether adding metformin to standard radiation and temozolomide (chemo) can improve outcomes for people with newly diagnosed glioblastoma of a specific metabolic subtype. It aims to see if this combination is safer and more effective than standard treatment alone.
Suresnes, Hauts de SeineAges 18 years+ - NCT04946773Recruiting
Deep liver testing study for cancer and non-cancer liver disease
