IMO-2125 skin injection for thick, early-stage melanoma
This trial tests whether an injection given into the skin (IMO-2125) can improve outcomes for people with thicker primary melanoma that has not spread to lymph nodes or other organs. Participants also have planned surgery to remove the tumor and check a sentinel lymph node.
AmsterdamAges 18 years+ - NCT04127552Recruiting
Adrenal mass screening and hormone effects on health
This study looks at how an accidentally found adrenal growth may affect heart and metabolic health, especially if it causes extra cortisol production. It may help explain which people are at higher risk and what monitoring or treatment could be useful.
Rome, ItalyAges 18–80 - NCT04135807RecruitingEarly Phase 1
Implantable device test for operable brain tumor patients
This early-phase trial tests a tiny implanted device placed during brain tumor surgery. It delivers very small doses of medicine directly to the tumor area for a short time, aiming to see if this approach is safe and workable in patients with certain gliomas.
Boston, MassachusettsAges 18 years+ - NCT04150744RecruitingPhase 2
New immune drug plus immunotherapy for liver cancer
This Phase 2 trial tests whether adding a new drug (RFA) to an immunotherapy medicine (carrizumab) works better than carrizumab alone for hepatocellular carcinoma, a type of liver cancer. It may help people whose tumors cannot be removed or transplanted and who have not started whole-body (systemic) cancer treatment yet.
Hangzhou, ZhejiangAges 18–75 - NCT04151342Recruiting
Study of Canadian adults with cancer rare DNA changes
This real-world study follows adults in Canada who have cancer that was tested and found to have rare molecular (DNA/protein) changes. It helps researchers understand how these rare findings show up and how care happens in everyday practice.
Calgary, AlbertaAges 18 years+ - NCT04170634Recruiting
CT scan study to assess bone strength in certain cancers
This study uses a CT scan to estimate how strong a cancer-affected bone area is, helping doctors evaluate fracture risk and bone management. It is aimed at adults with bone lesions from several common cancer types.
AngersAges 18 years+ - NCT04181970Recruiting
Study of sarcoma care quality across Europe and Latin America
This observational study looks at information from people with sarcoma to understand how care is delivered across different centers. It does not test a new treatment, but may help improve future care and planning.
Buenos AiresAges 18–120 - NCT04197414Recruiting
Urology DNA registry to personalize cancer care
This study builds a urology cancer “DNA registry” by analyzing circulating tumor DNA found in the blood. Your information and permission help researchers better personalize treatment for cancers like prostate, kidney, bladder, and ureter cancer.
SeoulAges 20 years+ - NCT04199026Recruiting
Tiny implanted device delivers drugs to sarcoma tumors
This trial tests an implantable device placed during planned surgery to deliver cancer medicines directly to sarcoma tumors and study how they affect the tumors. It may be an option if your sarcoma has come back or spread and surgery is part of standard care.
Houston, TexasAges 10 years+ - NCT04224064Recruiting
Blood test to help diagnose and predict liposarcoma
This study looks for a new blood test marker that may help doctors diagnose liposarcoma and estimate how it may behave over time. You may be asked for a blood sample and consent, and the study may follow you to see how well the test works.
MontpellierAges 18 years+ - NCT04222062RecruitingPhase 2
Compare Gliadel implant versus focused brain radiation
This Phase 2 study compares two ways to treat brain metastases: a Gliadel wafer placed during planned surgery versus focused stereotactic radiosurgery. It aims to see which approach works better and is safer for people with a limited number of brain tumor spots.
Detroit, MichiganAges 18 years+ - NCT04233788Recruiting
Brain mass imaging study using MRI to learn what causes it
This study uses MRI scanning to better describe a suspected brain mass and understand what it might be. You may be asked to lie in the scanner for about one hour, if you meet the study’s safety and eligibility rules.
