Conroe, TexasAges 18 years+ - NCT04251052Recruiting
Compare two surgeries to lower ovarian cancer risk in BRCA1 carriers
This study compares two risk-reducing surgery plans for people with a BRCA1 genetic change to see which approach helps lower ovarian cancer risk. You may be asked to have the study procedure sooner or later depending on your chosen plan.
Birmingham, AlabamaAges 35–50 - NCT04211259RecruitingEarly Phase 1
Loratadine to reduce bone pain during stem cell collection
This early trial studies whether loratadine (an allergy medicine) can reduce bone pain caused by G-CSF, which is used to help your body collect stem cells. If you have multiple myeloma and are preparing for stem cell mobilization, this may make treatment-related bone pain more tolerable.
New Brunswick, New JerseyAges 18 years+ - NCT04254133Enrolling by invitation
Study uses genetics to guide prostate cancer care and screening
This study collects saliva and health/family history information to learn how inherited (genetic) factors relate to prostate cancer. The goal is to improve how treatment and future screening are planned for people and families.
Seattle, WashingtonAges 35–89 - NCT04185935Recruiting
Genetic study of cancer in patients and their families
This study looks at DNA patterns in families where cancer may run in families, to better understand inherited (passed-down) cancer risk. You may be able to help even if you’re not sure whether your cancer is genetic—your family history and, if needed, medical records or tumor samples can be used.
Phoenix, ArizonaAges Any age - NCT04151082RecruitingPhase 1/Phase 2
Steroid therapy for late nerve damage after throat cancer radiation
This trial tests whether high-dose steroids (prednisone or methylprednisolone) can improve symptoms of nerve damage that may occur years after radiation treatment for oropharyngeal cancer. It includes a registry for tracking similar nerve issues in head and neck cancer survivors.
Houston, TexasAges 18 years+ - NCT04068649RecruitingPhase 2
Single high-dose radiation vs standard palliative radiation
This Phase 2 study compares a one-time, high-dose radiation treatment (SBRT) with the usual, shorter-course palliative radiation. The goal is to see which approach better relieves symptoms from metastatic (spread) cancer.
