- NCT03647072RecruitingPhase 3
Test drug to reduce stomach side effects during lymphoma chemotherapy
This Phase 3 trial studies whether a proton pump inhibitor (a stomach acid blocker) works better than histamine-blocking medicines when added to chemotherapy for DLBCL lymphoma. The goal is to improve how well chemotherapy is tolerated or how the treatment works.
CairoAges 18 years+ - NCT03687151Recruiting
Cancer registry for people living in a specific French region
This study helps build a population-wide cancer observatory (a real-world cancer record) for people in a specific region of France. It may help researchers better understand cancer patterns and needs in the area.
NiceAges Any age - NCT03731130Recruiting
Study on quality of life after rectal cancer treatment and surgery
This observational study follows people with rectal cancer who get radiation (with or without chemotherapy) before surgery. It aims to understand how these treatments affect quality of life after surgery.
Munich, BavariaAges 18 years+ - NCT04025450RecruitingPhase 1/Phase 2
Tested stronger combo for high-risk myeloma patients
This early-phase study compares two drug combinations—chidamide plus VRD versus VRD alone—to see which works better for primary high-risk multiple myeloma. The goal is to improve response while closely monitoring side effects and heart/lung safety.
Suzhou, JiangsuAges 18–80 - NCT02321423Recruiting
Research registry for pachyonychia congenita patients
This study builds an international database of people with pachyonychia congenita (or a closely related condition). Sharing your information may help researchers understand the condition better and improve future treatments.
Salt Lake City, UtahAges Any age - NCT03781531Recruiting
Blood tests to find hidden cancer after a blood clot
This study looks for “biomarkers,” or blood signs, that may help detect hidden (occult) cancer in people who recently had a blood clot in the leg or a lung clot. It may help doctors catch cancer earlier by improving detection after venous thromboembolism.
StockholmAges 18 years+ - NCT03807687Recruiting
Registry for people with pancreatic diseases
This is a registry that collects information from people who have a pancreatic disease. It may help doctors better understand different pancreatic conditions and improve future care.
VeronaAges 18 years+ - NCT03671252RecruitingPhase 3
Chemotherapy before surgery for rectal cancer vs chemo with radiation
This Phase 3 trial compares two treatment plans given before rectal surgery. It tests whether stronger chemotherapy alone works better than chemotherapy pills plus long-term radiation to improve outcomes for locally advanced rectal cancer.
Guangzhou, GuangdongAges 18–75 - NCT03385018Recruiting
Laparoscopic total stomach surgery trial for stomach cancer
This trial studies whether a minimally invasive (laparoscopic) removal of the entire stomach, along with lymph node removal, can be done safely and effectively for certain stomach cancers. It may be an option if your cancer is in the stomach, has limited spread to nearby lymph nodes, and can be fully removed.
SeoulAges 20–80 - NCT03919461RecruitingPhase 2
Preventing colon and rectal cancer spread after surgery
This Phase 2 study tests medicines given around the time of colon or rectal cancer surgery to help lower the chance the cancer will later spread to other parts of the body. If you are planned for curative (potentially curable) surgery and have no signs of spread yet, the trial may help prevent future metastases.
AfulaAges 20–80 - NCT03818334RecruitingPhase 2/Phase 3
Cyclophosphamide after transplant for blood cancer without sibling donor
This trial studies giving cyclophosphamide after a stem cell transplant when there is no matched sibling donor, but a well-matched unrelated donor is available. It aims to improve outcomes for people with blood cancers undergoing this transplant.
São Paulo, São PauloAges 1–75 - NCT02971085Recruiting
Registry for prostate cancer on active surveillance
This study follows men with low-risk prostate cancer who choose active surveillance (watching closely instead of immediate treatment). It aims to better track which monitoring results stay reassuring over time, and when treatment might be needed.
SeoulAges 40–80 - NCT03838718Recruiting
Registry study for adults after retroperitoneal sarcoma surgery
This study follows adults who have had surgery for a retroperitoneal sarcoma. It collects clinical and imaging information after treatment to better understand outcomes and guide future care.
Los Angeles, CaliforniaAges 18 years+ - NCT02803970Recruiting
Borderline ovarian tumor patient registry in Korea
This is a registry, meaning researchers collect and organize past medical information from people diagnosed with borderline ovarian tumors in Korea. It helps doctors better understand treatment patterns and outcomes over time, which may improve future care.
ChangwonAges Any age - NCT03925662RecruitingPhase 3
Mebendazole added to stage 4 colon cancer care
This trial studies whether adding mebendazole (an existing anti-parasite medicine) to standard treatment can improve outcomes for people with stage 4 colon cancer. You might qualify if you have stage 4 colorectal cancer and none of the key safety concerns.
CairoAges 18 years+ - NCT03196414RecruitingPhase 1/Phase 2
CAR T cell therapy for relapsed myeloma with multiple targets
This trial tests an immune therapy made from T cells to attack multiple markers on multiple myeloma cells (including CD138 and BCMA). It may help people whose myeloma has come back or resisted treatment, when there are no curative options left.
Suzhou, JiangsuAges 18–75 - NCT03934957Recruiting
Study of health in people living in Hamburg
This study follows adults living in Hamburg to better understand health and health-related factors over time. You may help researchers learn what influences health in this age group.
HamburgAges 45–74 - NCT03961373RecruitingPhase 3
Standard vs longer lymph node surgery after chemo for stomach cancer
This study compares two surgical approaches to remove lymph nodes after you’ve already had chemotherapy for stomach cancer. It aims to see whether removing lymph nodes in a more extended way improves outcomes without causing unacceptable side effects.
SienaAges 18–80 - NCT03048266Recruiting
Testing genes and blood chemistry in MEN1 pancreatic tumors
This study looks at blood chemistry (metabolomics) and genetic information in people who have MEN1, especially if they are being evaluated for pancreatic neuroendocrine tumors. It may help doctors better diagnose these tumors by finding patterns in test results.
Houston, TexasAges Any age - NCT03966443Recruiting
Fluciclovine PET/CT scan for people with multiple myeloma
This trial studies how a special PET/CT scan (using fluciclovine) may help doctors evaluate multiple myeloma. You might be eligible if you’re a candidate for stem cell transplant (ASCT).
OsloAges 18 years+ - NCT03941561RecruitingPhase 3
Shorter versus longer chemotherapy for stage II stomach cancer
This trial compares two lengths of an oral chemotherapy medicine (9 months vs 1 year) after surgery for stage II stomach cancer. It aims to see which schedule works better and is easier to complete, while checking safety for people without major health problems.
AnqingAges 18–75 - NCT03980002RecruitingPhase 2
New treatment for CLL using alternating two drug types
This trial studies an approach for people with newly diagnosed CLL/SLL (chronic lymphocytic leukemia or related disease) who need treatment. It tests whether alternating two types of chemotherapy with ibrutinib (a targeted pill) can control the disease better and safely.
Tianjin, Tianjin MunicipalityAges 18–75 - NCT04025164Recruiting
Shorter vs standard breast radiation after lumpectomy
This study compares a shorter course of radiation to a standard longer course after breast-conserving surgery (lumpectomy). It’s meant to see which schedule works just as well while focusing on safety and cancer control.
Guiyang, GuizhouAges 18–70 - NCT04074538Recruiting
Colorectal cancer study to help researchers learn patterns
This study is collecting information from people with newly diagnosed colon or rectal cancer, to better understand the disease and support future research. It may help you and others by improving how colorectal cancer is studied and potentially treated over time.
