This study tests two new radioactive drugs designed to find and image advanced breast or prostate cancer. The drugs use special imaging scans (PET and SPECT) to locate tumors and may help guide future treatment decisions.
Perth, Western AustraliaAges 18 years+ - NCT05983432RecruitingPhase 1
Study of BL-B01D1 for advanced lung and other solid tumors
This trial tests an experimental drug called BL-B01D1 for people with several types of advanced solid tumors, especially non-small cell lung cancer and breast cancer. It's designed for those whose cancer has continued to grow after standard treatments.
Beverly Hills, CaliforniaAges 18 years+ - NCT03451383Recruiting
Study brain changes in older breast cancer patients
This study follows older women with newly diagnosed breast cancer to see who might develop thinking or memory problems over time. It may help researchers understand early brain risk and how treatment and other factors relate to cognitive decline.
Washington D.C., District of ColumbiaAges 60–105 - NCT06906237Recruiting
Breast reconstruction study for early-stage breast cancer
This study looks at how well special breast-conserving surgery techniques work for women with early-stage breast cancer. It aims to see if these techniques provide good results and satisfaction over time.
PadovaAges 18 years+ - NCT07166042RecruitingPhase 3
Guided meditation during radiation for breast or gynecologic cancer
This study tests whether a guided meditation program during daily radiation therapy can help reduce stress and improve well-being for people with breast or gynecological cancer. You will be randomly assigned to either the meditation group or the usual care group.
Salt Lake City, UtahAges 18 years+ - NCT06480513Recruiting
Yoga for joint pain from hormone therapy in breast cancer
This trial tests whether a yoga program can help reduce joint and muscle pain caused by hormone therapy (like tamoxifen or aromatase inhibitors) in people with breast cancer. You must have finished your main treatments at least 12 weeks ago and have had pain for more than 3 months.
UtrechtAges Any age - NCT01034033Recruiting
Blood and tumor genetic study for BRCA and related risks
This study collects blood (and possibly tumor tissue) to learn how certain inherited gene changes relate to breast and ovarian cancer risk. It may help researchers understand which people are most likely to develop these cancers and how tumors differ in high-risk patients.
Stanford, CaliforniaAges 18 years+ - NCT07578116RecruitingPhase 3
Adding surgery and radiation for her2-positive breast cancer with a few spread spots
This trial tests whether adding surgery and radiation to the usual HER2-targeted treatment helps people with breast cancer that has spread to a few spots. You must have HER2-positive cancer that is newly spread, and you must be able to receive radiation to all tumor sites.
