This study tests if taking pyrrolitinib (a targeted medicine) can further reduce the risk of breast cancer returning in patients with HER2-positive early breast cancer who have already received trastuzumab after surgery.
Zunyi, GuizhouAges 18–75 - NCT05000294RecruitingPhase 1/Phase 2
Atezolizumab plus tivozanib for hard-to-treat “cold” cancers
This early-stage study tests whether combining atezolizumab and tivozanib can shrink advanced, hard-to-treat cancers that do not strongly activate the immune system (“immunologically cold”). It is for people whose cancer has already been treated or has no good standard options.
Gainesville, FloridaAges 18–99 - NCT05130801RecruitingPhase 1/Phase 2
MRI and pHLIP dye during breast surgery to map tumors
This trial tests whether a special MRI and an injected light-activated dye (pHLIP® ICG) can help doctors see and target breast cancer during surgery. You may be offered this approach around the time of breast-conserving surgery, to improve how well the tumor area is identified.
Montvale, New JerseyAges 18 years+ - NCT05490433Recruiting
Robot-assisted versus open nipple-sparing mastectomy with reconstruction
This trial compares two surgical approaches to remove the breast using a nipple-sparing mastectomy and do immediate breast reconstruction—either robot-assisted or open surgery. It aims to see how well each method works and how patients do afterward.
ChangwonAges 19–70 - NCT06766058Recruiting
Can aromatherapy reduce distress before breast cancer radiotherapy?
This trial tests if inhaling certain scents (aromatherapy) can help calm and reduce distress in breast cancer patients just before their first radiotherapy session.
SingaporeAges 21–99 - NCT03137095Recruiting
Study how chemotherapy affects brain function in breast cancer
This study looks at changes in thinking and brain function in people with early to locally advanced breast cancer before and during chemotherapy. You may also be offered a brain MRI in a separate optional part of the research to learn more about brain changes.
Rochester, New YorkAges 21 years+ - NCT06839547Recruiting
Testing a new drug with radiation for advanced breast cancer brain tumors
This study looks at how well a new anti-tumor drug works when given along with radiation therapy for people whose advanced breast cancer has spread to the brain. It may help the radiation work better and control the cancer longer.
BeijingAges 18 years+ - NCT06162559RecruitingPhase 1
Targeted therapy before surgery for HER2+ breast cancer
This trial tests a combination of three targeted drugs (trastuzumab, pertuzumab, and tucatinib) without chemotherapy before surgery for HER2-positive breast cancer. It aims to see if this approach can shrink tumors effectively while avoiding chemotherapy side effects.
AmsterdamAges 18 years+ - NCT05323409Recruiting
Better overall care for certain cancer patients
This study looks at how to improve day-to-day support and coordination between cancer doctors and primary care doctors for people with certain early cancers. It may help if you have other ongoing health problems (like diabetes or high blood pressure) or lifestyle factors that need ongoing management during cancer treatment.
Houston, TexasAges 18 years+ - NCT07601178RecruitingPhase 2
Immunotherapy and targeted drugs for advanced triple-negative breast cancer
This trial tests a combination of four drugs—two immunotherapies (QL1706), an anti-angiogenic agent (anlotinib), and chemotherapy (nab-paclitaxel)—as a first-line treatment for advanced triple-negative breast cancer. The goal is to see if this combination slows or stops cancer growth better than standard treatment alone.
Nanjing, JiangsuAges 18–75 - NCT07658170Recruiting
Fat graft with platelet-rich fibrin for breast reconstruction after lumpectomy
This trial tests using a patient's own fat plus a special blood product (platelet-rich fibrin) to rebuild the breast right after a lumpectomy for breast cancer. It may help improve healing and appearance for women with early-stage, hormone-sensitive breast cancer.
