This trial tests seviteronel together with standard chemotherapy to treat certain types of advanced breast cancer that has spread. It’s looking to see how well the combination works and how safe it is, especially for cancers that are androgen-receptor positive.
Darlinghurst, New South WalesAges 18 years+ - NCT04965064RecruitingPhase 2
Neratinib plus capecitabine for HER2-negative breast cancer brain mets
This study tests whether neratinib plus capecitabine can slow or shrink breast cancer that has spread to the brain. It is for people whose cancer shows an “overactive HER2 signal” on a specific tumor test, even though their cancer is labeled HER2-negative.
Rochester, New YorkAges 18 years+ - NCT05095207RecruitingPhase 1/Phase 2
Abemaciclib and bicalutamide for HER2-negative metastatic breast cancer
This Phase 1/2 trial tests whether combining abemaciclib with bicalutamide can slow or shrink HER2-negative, androgen receptor–positive (AR-positive) metastatic breast cancer. It mainly looks at safety and side effects, and also whether the combination can help patients with this type of breast cancer.
New York, New YorkAges 18–90 - NCT05181033RecruitingPhase 2
Lenvatinib plus letrozole versus fulvestrant for metastatic breast cancer
This Phase 2 study compares a combination medicine (lenvatinib plus letrozole) against fulvestrant to treat metastatic estrogen-receptor positive, HER2-negative breast cancer after the cancer has grown despite hormone therapy plus a CDK4/6 inhibitor. It may help by finding a more effective treatment option after your first lines have stopped working.
SingaporeAges 18–99 - NCT05270213RecruitingPhase 1
RBS2418 for advanced cancers after standard treatments
This early-phase study tests RBS2418 in people with advanced, metastatic solid tumors that have not responded to standard treatment. It aims to see if the drug can shrink tumors or help control disease, and to learn what doses are safest.
Scottsdale, ArizonaAges 18 years+ - NCT05394103RecruitingPhase 1/Phase 2
Testing a targeted pill for hard-to-treat solid tumors
This trial tests a new medicine (Q901) that targets a specific cell-control pathway to treat advanced cancers that have stopped responding to standard care. It’s mainly for people with certain solid tumor cancers, aiming to see whether the drug can shrink tumors or control disease.
