This trial tests if brodalumab, an antibody that blocks a specific immune pathway (IL-17), can help control side effects caused by immunotherapy cancer treatment. It is for people with advanced solid organ cancers who have immune-related side effects that are suspected to involve IL-17.
New York, New YorkAges 18 years+ - NCT03643861Recruiting
Radiation after lumpectomy for certain early breast cancers
This trial tests a short, highly targeted radiation plan given in five sessions after lumpectomy for early-stage breast cancer. It may help treat the remaining breast area while aiming to limit exposure to healthy tissue.
Birmingham, AlabamaAges 18–99 - NCT07376174Recruiting
HER2-positive breast cancer and dual-target therapy study
This study looks at how well a combination of two targeted drugs (trastuzumab and pertuzumab) works for people with HER2-positive breast cancer that hasn't spread. It aims to understand how HER2 levels affect treatment outcomes after surgery.
Jinan, ShandongAges 18 years+ - NCT05406232Recruiting
Radiation study to track immune changes in breast cancer
This study gives a short course of radiation to the breast or chest wall and measures how your immune system responds. It may help doctors better understand which immune changes happen after radiation and how this could improve palliative (symptom-relieving) care.
Houston, TexasAges 18 years+ - NCT04469296Recruiting
Diet changes before surgery for hormone-receptor breast cancer
This trial tests whether changing your diet before your breast surgery can help people with early, hormone-receptor (ER/PR+) breast cancer. It focuses on patients who have not started treatment yet and want to keep surgery as the main treatment.
Montpellier, HeraultAges 18–80 - NCT06686394RecruitingPhase 1/Phase 2
Patritumab deruxtecan combinations for advanced HER2-positive breast cancer
This trial tests a new drug, patritumab deruxtecan, combined with other anti-cancer drugs for people with HER2-positive breast cancer that has spread or cannot be removed by surgery. It aims to see if these combinations can shrink tumors or slow cancer growth.
Aurora, ColoradoAges 18 years+ - NCT05283330RecruitingPhase 1
Tested 212Pb imaging drug for certain advanced GRPR tumors
This early-phase study tests how safe and tolerable an experimental radiation drug is for adults with certain advanced or metastatic cancers that show a target called GRPR. Doctors will also use special scans to confirm the tumor has the target so the treatment can be delivered to the right place.
Chicago, IllinoisAges 18 years+ - NCT07552467Recruiting
PET Imaging Scan for Detecting Cancer Using New Radioactive Tracer
This study tests a new type of imaging scan (PET/CT or PET/MR) that uses a radioactive tracer to help doctors better detect and diagnose various cancers. The scan targets a specific protein found in tumors, which may help identify cancer more accurately than standard imaging.
Wuhan, HubeiAges 18 years+ - NCT07069595RecruitingPhase 2
Blood test for breast cancer survivors at risk of recurrence
This trial uses a simple blood test to look for leftover cancer DNA in people with triple-negative breast cancer who still have disease after chemotherapy and surgery. It aims to catch any early signs of the cancer coming back.
Chapel Hill, North CarolinaAges 18 years+ - NCT06695845RecruitingPhase 2
Study of zanidatamab for HER2-positive solid tumors
This trial tests a drug called zanidatamab in people with advanced solid tumors that have high levels of HER2 protein (called HER2-positive). It aims to see if zanidatamab can shrink or slow the growth of these tumors.
Prescott, ArizonaAges 18 years+ - NCT07469709Recruiting
Cancer risk study using genetics and monitoring
