Avasopasem for advanced HR+ breast cancer after CDK 4/6 inhibitor
This trial tests a drug called avasopasem for people with hormone receptor-positive, HER2-negative breast cancer that has spread and gotten worse despite treatment with a CDK 4/6 inhibitor (ribociclib or abemaciclib) and hormonal therapy. It aims to see if adding avasopasem can help control the cancer.
San Antonio, TexasAges 18 years+ - NCT06538896RecruitingPhase 2
Tislelizumab and nab-paclitaxel for advanced triple-negative breast cancer with bone spread
This trial tests a combination of two drugs, tislelizumab (an immunotherapy) and nab-paclitaxel (a chemotherapy), as the first treatment for advanced triple-negative breast cancer that has spread to the bones. It aims to see if this combination can help shrink or control the cancer.
Hangzhou, ZhejiangAges 18–70 - NCT05190094RecruitingPhase 2
Test blood-based laser scan to guide first-line breast cancer treatment
This Phase 2 study uses a specialized laser test on a blood sample to predict how well palbociclib plus letrozole or anastrozole will work. It’s for certain postmenopausal women with HER2-negative, hormone-receptor positive, advanced (stage IIIb/IV) breast cancer.
BlidaAges 18 years+ - NCT07743190RecruitingPhase 2
Lighter chemo for early-stage triple-negative breast cancer with high immune cells
This trial tests a less intense chemotherapy regimen (without one of the standard drugs) combined with immunotherapy for people with early-stage triple-negative breast cancer whose tumors have a high level of immune cells (TILs). The goal is to see if this approach is effective while reducing side effects.
Syracuse, New YorkAges 18 years+ - NCT06193525RecruitingPhase 2
Talazoparib for advanced breast cancer with a DNA repair defect
This trial tests a drug called talazoparib (a PARP inhibitor) for advanced breast cancer that has a specific DNA repair defect (HRD) or a BRCA mutation. The goal is to see if the drug works better when the patient's tumor is tested for this defect just before treatment.
