Nilotinib and paclitaxel for rare solid tumors
This study tests a combination of two drugs, nilotinib and paclitaxel, in people with certain rare cancers that have not responded to standard treatments. It aims to see if this combination can shrink tumors or slow cancer growth.
Bethesda, MarylandAges 18–120 - NCT03740503Recruiting
Study genes in people who respond unusually to treatment
This study looks at stored tumor samples to understand why some people respond much better or much worse than expected. The goal is to learn what the tumor’s genes might be telling doctors about response to treatment.
Toronto, OntarioAges 18 years+ - NCT04166006RecruitingPhase 2
Vaccine made from your tumor cells after surgery for rare cancers
This trial tests a personalized vaccine made from your own tumor material, aiming to lower the chance cancer returns after surgery. It is for people whose rare cancers have been removed completely and who have no standard treatment available after surgery.
Meldola, FCAges 18 years+ - NCT05733806Recruiting
Study for rare gynecologic cancers
This study is looking at people with rare cancers affecting the female reproductive system. It may help researchers learn more about how these cancers behave and how best to follow patients over time.
MilanAges Any age - NCT04923178Recruiting
Natural history study of bladder and other genital cancers
This study follows people with urothelial cancer and certain rare genital (genitourinary) cancers over time to learn how these diseases progress. It may help researchers understand patterns of symptoms and outcomes, even if it is not a drug trial.
Bethesda, MarylandAges 18 years+ - NCT05217407Recruiting
Registry study for people with rare or advanced cancers
This is a study that collects information about people with rare cancers (or cancers where the source is unknown) and advanced-stage cancer. It helps researchers build a knowledge database to improve understanding and care for these cancers in Asia.
Chuo-ku, TokyoAges 18 years+ - NCT04498767Recruiting
Radiation to treat a few metastatic spots in rare cancers
This trial studies whether stereotactic (high-precision) radiation given in a few sessions can control rare cancers that have spread to a small number of sites. It aims to help by treating all known spots while keeping side effects manageable.
AnderlechtAges 18 years+ - NCT02305654RecruitingPhase 3
Trial for penile squamous cancer with swollen groin or pelvis nodes
This Phase 3 study tests treatment options for penile squamous cell cancer that has spread to nearby groin and/or pelvic lymph nodes (but not to distant organs). If you have the right stage and haven’t had certain prior treatments, this trial may offer a structured treatment plan and close monitoring.
Los Angeles, CaliforniaAges 18 years+ - NCT03340506RecruitingPhase 4
Follow-on treatment study for dabrafenib and trametinib
This study lets people who finished a prior dabrafenib/trametinib trial (sponsored by Novartis or former GSK) continue those medicines if the study doctor thinks it will help. It mainly focuses on ongoing treatment benefit rather than testing a new drug.
Scottsdale, ArizonaAges 18–100 - NCT06683846RecruitingPhase 2
Ivonescimab for advanced rare tumors: a safety & early-efficacy study
This trial tests a drug called ivonescimab in people with advanced, rare tumor types that have spread (stage IV). The goal is to see if the drug is safe and whether it can shrink tumors or slow their growth.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05852522Recruiting
Testing treatment planning to help eradicate rare advanced cancers
This trial looks at a more tailored way to choose treatment for people with rare cancers that have spread or grown locally and can’t be cured with standard therapies. The goal is to better target the tumor to improve the chance of tumor shrinkage or eradication.
HeidelbergAges 18 years+ - NCT05483374Recruiting
Head and neck cancer registry for adult patients
This study builds a European database (registry) of adults with certain head and neck cancers to better understand how these cancers are diagnosed and treated over time. It may help future care by collecting real-world information, rather than testing a new medicine.
Brno, BrnoAges 18 years+ - NCT04838327Recruiting
