Birmingham, AlabamaAges 18 years+ - NCT05874492Recruiting
Spa therapy for radiation-related skin fibrosis after cancer
This trial tests whether a spa therapy program can improve “fibrosis,” or stiffened/scarred tissue and related skin problems, after radiotherapy for breast cancer or upper head/neck cancers. It aims to see if treatment can improve quality of life for people who still have moderate-to-worse symptoms months after radiation.
BordeauxAges 18 years+ - NCT05877859Recruiting
Testing pembrolizumab with chemo before breast cancer surgery
This trial studies whether adding pembrolizumab (an immunotherapy) to standard chemotherapy before surgery improves immune and clinical responses in people with early-stage triple-negative breast cancer. You may benefit by getting a potentially more effective treatment plan, while the study team closely monitors your response.
Atlanta, GeorgiaAges 18 years+ - NCT05878964Recruiting
Study of skin health and quality of life during cancer treatment
This trial looks at how cancer treatments (anti–PD-1/PD-L1/CTLA-4 medicines or CDK inhibitors) affect your skin and overall quality of life. You may fill out questionnaires during the study to help researchers understand changes over time.
RomaAges 18 years+ - NCT05891561RecruitingPhase 2
Short antibody treatment after surgery for early HER2+ breast cancer
This Phase 2 study tests a shorter schedule of trastuzumab and pertuzumab combined with chemotherapy (taxanes) to reduce breast cancer coming back after surgery. It mainly helps people with early-stage, HER2-positive breast cancer that has not spread, by testing whether a shorter plan still works well and is tolerable.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05896865Recruiting
Personalized breast cancer radiation based on tumor biology
This trial studies whether adjusting radiation dose using how the tumor behaves can improve outcomes for people with locally advanced breast cancer that has spread to certain nearby lymph nodes. It may help deliver the right radiation intensity while avoiding unnecessary exposure.
SeoulAges 19 years+ - NCT05898009Recruiting
Study BRCA2 gene changes in breast cancer in Reunion
This study looks at how often certain BRCA2 gene changes occur in people in Réunion who have breast cancer. Your participation may help doctors understand breast cancer risk in the local community and guide future care.
Saint-PierreAges 18 years+ - NCT05898789Recruiting
Virtual rehab program for cancer survivors
This trial tests a virtual (online) rehabilitation and exercise program for people after breast, colorectal, head and neck, or certain blood cancers. It may help improve recovery and daily functioning by supporting safe activity and targeted rehab after treatment.
Toronto, OntarioAges 18 years+ - NCT05900206RecruitingPhase 2
Trastuzumab deruxtecan vs standard chemotherapy before breast surgery
This Phase 2 study compares trastuzumab deruxtecan to standard chemotherapy given before surgery for HER2-positive breast cancer. It aims to see which treatment works better to shrink the tumor and spread before the operation.
MalmöAges 18 years+ - NCT05902507Recruiting
MRI guidance during breast cancer radiation treatment
This trial studies using MRI images to help plan and guide radiation therapy after breast-conserving surgery. It may help doctors target the right area more accurately while keeping treatment standard and safe.
San Francisco, CaliforniaAges 18 years+ - NCT05909332RecruitingPhase 3
Tested antivascular drug plus chemo versus chemo alone for TNBC
This Phase 3 trial compares an “anti-blood-vessel” drug added to chemotherapy versus chemotherapy alone for people with stage II–IIIC triple-negative breast cancer that has been completely removed with surgery. The goal is to see if adding the study drug improves outcomes after surgery (adjuvant treatment).
Beijing, Beijing MunicipalityAges 18–70 - NCT05919108RecruitingPhase 2
Neratinib before surgery for HER2-mutated invasive lobular breast cancer
This Phase 2 trial tests neratinib given before surgery to treat stage I–III invasive lobular breast cancer that has a specific HER2 mutation and is hormone-receptor positive. It may help shrink the tumor and improve control of cancer before and after surgery.
Atlanta, GeorgiaAges 18 years+ - NCT05921279Recruiting
Study heart events in people with breast cancer
This study looks at what heart-related side effects happen in women with breast cancer who are planned to receive chemotherapy. It may help doctors better understand and monitor these risks during treatment.
GalwayAges 18–90 - NCT05928429Recruiting
Cold treatment to prevent nerve pain from weekly paclitaxel
This trial tests whether cryotherapy (cooling the hands/feet during chemo) can prevent or lessen nerve pain caused by paclitaxel in people with early breast cancer. It may help you stay more comfortable and function better during treatment.
CopenhagenAges 18 years+ - NCT05933733Recruiting
Salvage treatment for breast cancer that returned locally
This trial looks at how well “salvage” treatments work for breast cancer that has come back only in the local area (like the chest wall or nearby lymph nodes), without spreading to distant organs. It also tracks side effects to better understand the risks and benefits for patients who need additional treatment.
SeoulAges 18–100 - NCT05935150Recruiting
Skipping lymph node surgery in early breast cancer
This trial studies whether you can safely avoid a lymph node biopsy in the armpit for early breast cancer when scans and exams look negative. It may reduce surgery-related side effects while still keeping cancer care on track.
Nanjing, JiangsuAges 18–70 - NCT05939830Recruiting
Skipping axillary lymph node surgery after treatment response
This study looks at whether some breast cancer patients can safely skip a surgery that removes lymph nodes in the armpit after their initial (pre-surgery) treatment shows the armpit is likely clear. It may reduce surgical side effects if the armpit truly responds well.
NanjingAges 18–70 - NCT05949541RecruitingPhase 2
Everolimus with first-line hormone therapy for specific breast cancer
This Phase 2 trial tests whether adding everolimus to standard first-line hormone (endocrine) therapy can better control a certain type of advanced breast cancer. It is designed for people whose tumor matches a specific “SNF1 subtype.”
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05950945RecruitingPhase 3
Trastuzumab deruxtecan for HER2-low metastatic breast cancer
This trial tests a targeted antibody-drug medicine (trastuzumab deruxtecan, T-DXd) in people with metastatic breast cancer that is HER2-low or HER2 IHC 0. It may help by treating tumors that haven’t previously received anti-HER2 treatment in the metastatic setting.
Miami Beach, FloridaAges 18 years+ - NCT05954442RecruitingPhase 3
Everolimus plus chemo for advanced triple-negative breast cancer
This Phase 3 study tests whether adding everolimus to chemotherapy (chosen by the treating team) can improve outcomes in advanced triple-negative breast cancer, specifically a subtype linked to PAM pathway changes. It may help patients who have not yet had treatment for advanced/metastatic disease.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05957068Recruiting
Exercise program for breast cancer after surgery
This study tests an exercise intervention for people with early-to-mid stage breast cancer soon after curative breast surgery (and after chemo and/or radiation if you had it). It may help improve recovery, physical strength, and overall wellbeing by making exercise safer and more structured during this period.
SingaporeAges 21–99 - NCT05959291Recruiting
Stopping long-term anti-HER2 therapy in stable metastatic breast cancer
This study asks whether some people with HER2-positive metastatic breast cancer who have been stable for a long time can safely stop their ongoing (maintenance) anti-HER2 treatment. It also uses blood testing and close imaging follow-up to watch for early signs that treatment needs to restart.
