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 - NCT05559164RecruitingPhase 2
Statins to protect the heart during HER2 breast cancer treatment
This trial tests whether a cholesterol medicine (a statin) can lower the risk of heart damage in people receiving HER2-targeted breast cancer therapy. If you qualify, you may be given a statin and followed with heart tests and blood work to watch for safety and benefit.
Elizabeth, New JerseyAges 18 years+ - NCT05635487RecruitingPhase 2
Neoadjuvant treatment for HER2-positive breast cancer with SHR-A1811
This trial tests whether SHR-A1811 alone, or together with pyrotinib, given before surgery, can shrink HER2-positive breast cancer. It may help you respond better to treatment while making surgery easier.
Shenyang, LiaoningAges 18–75 - NCT05704829RecruitingPhase 2
Trastuzumab-deruxtecan before surgery for HER2-positive early breast cancer
This trial compares giving trastuzumab-deruxtecan before surgery versus standard chemotherapy plus trastuzumab and pertuzumab. It aims to see which approach works better to shrink or control HER2-positive early breast cancer and improve outcomes.
Baden-Baden, Baden-WurttembergAges 18 years+ - NCT07340398RecruitingPhase 2
Testing new drug combos for HER2-positive breast cancer not responding to first therapy
This trial tests a new combination of drugs for people with HER2-positive early breast cancer whose tumors did not respond well to the first round of standard targeted therapy plus chemo. The goal is to see if switching to trastuzumab-rezetecan plus pertuzumab or a different chemo combo (nab-paclitaxel, carboplatin, trastuzumab, and pyrotinib) can shrink the tumor before surgery.
HangzhouAges 18–75 - NCT06225505Recruiting
Early detection of triple-negative breast cancer return
This trial uses blood tests to look for signs of cancer returning early in women who had triple-negative breast cancer. If caught early, doctors can start treatment sooner.

Testing three CDK4/6 pills to change the immune response
This phase 2 trial compares ribociclib, palbociclib, and abemaciclib to see how each one affects your body’s immune response in estrogen- and/or progesterone-receptor–positive, HER2-negative early breast cancer. If you fit the stage and health requirements, joining could help doctors learn which treatment best “modulates” the immune system.
TaipeiAges 20 years+ - NCT05862064RecruitingPhase 3
Adding an immune drug and anti-blood-vessel treatment to chemo
This study tests whether adding an immune therapy (a PD-1 antibody) plus a blood-vessel–blocking treatment to standard chemo improves outcomes for people with surgically treated triple-negative breast cancer. Everyone gets chemotherapy, but some will also get the added drugs to try to reduce cancer coming back.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05989347RecruitingPhase 1
Dapagliflozin with chemo for breast cancer
This trial tests whether adding the drug dapagliflozin (a pill that lowers blood sugar) to standard chemotherapy before breast cancer surgery can improve outcomes. It is for women with high insulin levels and a higher BMI who are about to start chemotherapy.
