Testing four breast cancer medicines for stage II–III ER+/PR+/HER2+ cancer
This trial studies a combination of anti-cancer medicines (including trastuzumab and hormone therapy) for women with stage II–III breast cancer that is ER-, PR-, and HER2-positive. It aims to improve outcomes by attacking the cancer in different ways.
Shenyang, LiaoningAges 18–75 - NCT05241119Recruiting
Lymph node mapping to guide surgery after chemotherapy
This study tests using a special carbon-based tracing method to help doctors check which lymph nodes to treat during surgery after you finish chemotherapy. It may improve how accurately the surgical plan targets cancer in the armpit (axillary) lymph nodes.
Shenyang, LiaoningAges 18–70 - 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+ - NCT05289258Recruiting
Barlow-style program for thinking and memory problems after breast cancer
This trial tests a structured “Barlow Protocol” program to help improve mild to moderate thinking and memory problems in people who finished breast cancer chemotherapy. It may help if your cognitive symptoms started after treatment and you’re not already in similar therapy.
CórdobaAges 18–70 - NCT05291507RecruitingEarly Phase 1
MRI-guided focused ultrasound for breast cancer during surgery
This early study tests whether a device that uses focused ultrasound (guided by MRI) can be safely used during surgery for women with invasive breast cancer. It mainly looks at feasibility—whether the treatment can be delivered as planned and is safe.
Salt Lake City, UtahAges 18 years+ - NCT05293470Recruiting
Tracking the real-world effects of Piqray in Korea
This study monitors how well and how safely Piqray works for people in Korea in routine care. You may be invited if your breast cancer matches specific genetic and receptor test results and you are starting Piqray for the first time.
Cheonan Si, Chungcheongnam-doAges 18–100 - NCT05296564RecruitingPhase 1/Phase 2
TCR cell therapy for NY-ESO-1 positive metastatic cancers
This study tests a customized immune-cell treatment made from your own T cells to attack cancers that have NY-ESO-1. It may help shrink tumors in people with metastatic or hard-to-treat cancer when other treatments have not worked.
JerusalemAges 18–70 - NCT05313191Recruiting
Proton therapy for tumors after prior radiation
This study looks at whether a type of proton beam treatment can be given safely and effectively to tumors that have already been treated with radiation before. It may help people whose tumors came back or persisted after earlier radiation, using a specific proton method called pencil beam scanning.
New York, New YorkAges 18 years+ - NCT05325632RecruitingPhase 2
HER2 breast cancer vaccine plus chemo and targeted antibodies
This Phase 2 study tests a personalized immune-therapy vaccine made from your immune cells, given with weekly paclitaxel and HER2-targeted antibodies (trastuzumab and pertuzumab). It aims to improve treatment outcomes for people with HER2-positive breast cancer before standard local treatment (like surgery and radiation).
Tampa, FloridaAges 18 years+ - NCT05328258RecruitingPhase 3
Triptorelin to help protect fertility during cancer chemotherapy
This Phase 3 study tests whether a hormone medicine called triptorelin (a GnRH “fertility-protecting” medicine) can better protect ovarian function while you receive chemotherapy. The goal is to help preserve fertility and reduce the risk of early ovarian failure from cancer treatment.
GothenburgAges 14–42 - NCT05341141Recruiting
Cold therapy plus compression to prevent nerve damage from chemo
This trial tests whether using cold therapy (cryotherapy) together with compression can lower the chance of numbness, tingling, or pain in the hands and feet caused by chemotherapy. It may help people planning chemotherapy for breast cancer stay more comfortable and function better.
Beijing, Beijing MunicipalityAges 20–70 - NCT05366699Recruiting
Procedure to help prevent arm swelling after breast surgery
This trial studies a new procedure meant to lower the chance of getting lymphedema (arm swelling) after breast cancer surgery that removes lymph nodes in the armpit. It may help patients reduce the risk of long-term arm swelling, especially after lymph node dissection.
San Francisco, CaliforniaAges 18–75 - NCT05366881Recruiting
Blood test study to spot early cancer signal and cancer leftovers
This observational study checks whether a blood test (a “cfDNA” test) can detect early signs of cancer or small amounts of cancer left after treatment. It may help doctors use a simple blood sample to improve cancer detection and follow-up.
Duarte, CaliforniaAges 40 years+ - NCT05381038RecruitingPhase 1/Phase 2
Personalized azacitidine combinations for breast or stomach cancer
This Phase 1/2 trial tests different combinations that include azacitidine, chosen based on your tumor’s lab “response markers” and past drug-sensitivity screening. It aims to find safer dosing and see whether these personalized combinations can shrink solid tumors such as breast or stomach cancer.
SingaporeAges 21–99 - NCT05403177Recruiting
Share your cancer data and samples for Ontario research
This study collects and combines medical records, genetic (genomic) data, and tumor/blood samples from people with cancer. It helps researchers build and improve a large “gold standard” cancer dataset that can support future studies and better understanding of cancer.
