Recruiting studies
- NCT06781762Recruiting
Breast cancer hormone therapy and its effects on heart and brain
This study looks at how starting a common hormone therapy for breast cancer (aromatase inhibitors) affects your heart and brain health over the short term. It compares women starting this treatment to healthy women who are not on the therapy.
Toronto, OntarioAges Any age - NCT05491083RecruitingPhase 1/Phase 2
Pembrolizumab plus ADG106 for advanced triple-negative breast cancer
This early-phase study tests pembrolizumab (an immune therapy) combined with ADG106 in people with advanced solid tumors, and specifically triple-negative breast cancer. It looks at whether the treatment can shrink tumors and improve outcomes for cancers that are progressing despite prior therapy.
SingaporeAges 21–99 - 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 - NCT05804578Recruiting
Blood test monitoring for metastatic breast cancer treatment
This trial studies using a blood test to monitor how treatment is working in people with metastatic breast cancer. It may help your care team track your cancer over time with a simpler test.
Kingston, OntarioAges 18 years+ - NCT06767527RecruitingPhase 3
AK112 plus chemo for first-line triple-negative breast cancer
This trial tests a new immunotherapy drug called AK112 combined with chemotherapy (nab-paclitaxel) for people with advanced triple-negative breast cancer who haven't had treatment yet. The goal is to see if AK112 works better than a placebo at shrinking tumors and helping people live longer.
BeijingAges 18–75 - NCT06764940RecruitingPhase 2
Utidelone and capecitabine for HER2-negative breast cancer with brain metastases
This trial tests if the combination of Utidelone and capecitabine can shrink brain metastases in people with HER2-negative breast cancer. It is designed for those whose cancer has spread to the brain and who have not had many prior treatments.
Duarte, CaliforniaAges 18 years+ - NCT06765590Recruiting
Paclitaxel (albumin-bound) bioequivalence study in breast cancer
This study tests whether a new version of paclitaxel (albumin-bound) works the same as the approved version in people with breast cancer. It's for patients whose cancer has spread or returned after other treatments, or those for whom this drug is recommended by treatment guidelines.
Luoyang, HenanAges 18–75 - NCT06765707Enrolling by invitation
Monitoring symptoms to improve medication use in breast cancer
This trial tests if tracking how you feel and reporting your symptoms can help women with hormone receptor-positive breast cancer take their hormone-blocking medication more consistently. It may be a good fit if you have been prescribed aromatase inhibitors or similar therapy and have had trouble taking it as directed.
Chicago, IllinoisAges 18 years+ - 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 - NCT06771609RecruitingPhase 2
Immunotherapy plus low-dose chemo for advanced triple-negative breast cancer
This study tests a combination of an immunotherapy drug (PD-L1 inhibitor) with a special low-dose chemotherapy regimen (VEX) plus optional radiation for advanced triple-negative breast cancer. The goal is to see if this approach works better than standard treatments.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06762483Recruiting
Blood test for gene changes in advanced breast cancer
This trial uses a simple blood test to look for two specific gene changes (ESR-1 and gBRCA) in people with hormone receptor-positive, HER2-negative breast cancer that has spread. It aims to detect these mutations earlier and help guide future treatment decisions.
Milan, ItalyAges 18 years+ - NCT06761196Recruiting
Quality of life after breast cancer surgery
This study looks at how breast cancer surgery affects your quality of life. It includes people with any stage of breast cancer (or at high risk) who need breast surgery under general anesthesia. The goal is to learn how to better support your recovery and well-being.
ColmarAges 18 years+ - NCT06757634RecruitingPhase 3
A study of gedatolisib for first-line advanced breast cancer
This trial tests a new targeted therapy called gedatolisib for people with HR-positive, HER2-negative advanced breast cancer who have not yet received treatment for metastatic disease. It aims to see if adding this drug to standard hormone therapy can help control the cancer longer.
Jonesboro, ArkansasAges 18 years+ - NCT06738563Recruiting
Breast milk and virus transmission study
This study looks at whether breast milk can carry or spread different viruses. It is for women who donate to a specific milk bank in France.
ParisAges 18 years+ - NCT05494502Recruiting
Nerve block to reduce long-term pain after breast surgery
This trial tests whether a specific pain-numbing nerve block given during mastectomy can reduce chronic (long-lasting) pain after breast cancer surgery. It may help some people use less pain medicine later by lowering nerve-related pain after surgery.
Beijing, Beijing MunicipalityAges 18–85 - NCT06748222RecruitingPhase 3
Online mindfulness program for breast cancer survivors
This trial tests a 6-week online mindfulness program to help breast cancer survivors manage mild to moderate depression. You may qualify if you finished active treatment within the last 5 years and can use a digital device.
Phoenix, ArizonaAges 18–50 - NCT06305312Recruiting
Community help for women with abnormal mammogram results
This study connects people who had an abnormal mammogram result with community resources to address social needs like food, housing, or transportation. The goal is to reduce barriers to follow-up care and promote health equity.
Salt Lake City, UtahAges 18 years+ - NCT06358625Recruiting
Study of brain recurrence risk in HER2-positive breast cancer
This study looks at women with HER2-positive breast cancer who will get chemotherapy before surgery. The goal is to find out what factors might increase the chance of the cancer spreading to the brain later on.
RennesAges 18 years+ - NCT06732323RecruitingPhase 3
Study of ESG401 for triple-negative breast cancer that has spread
This trial tests a new drug, ESG401, for people with triple-negative breast cancer that has come back or spread and cannot be removed by surgery. It compares ESG401 to standard chemotherapy options to see which works better.
BeijingAges 18 years+ - NCT06732336RecruitingPhase 1/Phase 2
PET scan for HER2-low breast cancer
This trial uses a special PET scan to see if your breast cancer has low levels of a protein called HER2. This could help doctors choose the right treatment for you.
Sherbrooke, QuebecAges 18 years+ - NCT06731894RecruitingPhase 2
Cannabis for nerve pain after chemotherapy in breast and colon cancer survivors
This trial tests whether a cannabis-based product can reduce nerve damage (neuropathy) caused by chemotherapy in people who have finished treatment for breast or colon cancer. It focuses on survivors who still have pain, numbness, or tingling in their hands or feet.
Duarte, CaliforniaAges 18 years+ - NCT06728579RecruitingPhase 2
Group therapy for joint pain in breast cancer survivors
This study tests two supportive group programs—one using mindfulness skills, the other providing supportive talk therapy—to help breast cancer survivors manage joint pain caused by hormone-blocking pills. If you have ongoing joint pain and are taking an aromatase inhibitor, you may be able to join a free, video-based group.
