BlidaAges 18 years+ - NCT04997993RecruitingPhase 1
Leflunomide for PTEN-altered or HER2-negative metastatic cancers
This Phase 1 trial studies whether leflunomide can slow or control advanced (metastatic) cancers in people whose tumors have specific PTEN changes or who have HER2-negative breast cancer. It’s primarily a safety-and-dosing study, but it may offer benefit if your cancer matches the tumor marker requirements.
New York, New YorkAges 18 years+ - NCT05075512RecruitingPhase 2
Anlotinib with fulvestrant for advanced, HR-positive, HER2-negative breast cancer
This trial studies whether adding anlotinib (a targeted medicine) to fulvestrant (a hormone-blocking injection) can improve outcomes for people with advanced HR-positive, HER2-negative breast cancer. It focuses on safety and effectiveness when cancer has returned or progressed after hormone treatments.
Hangzhou, ZhejiangAges 18 years+ - NCT04889469Recruiting
Breast size reduction for people with heavy, painful breasts
This study looks at who might qualify for breast reduction surgery in Sweden’s public healthcare system. It aims to match people with very large breasts and related symptoms to treatment criteria, and compare groups who do and do not meet those standards.
GothenburgAges 18–75 - NCT05420779RecruitingPhase 2
TSL-1502 for breast cancer with BRCA gene mutations
This Phase 2 trial tests TSL-1502 capsules, a targeted medicine for breast cancer, in people whose blood test shows a harmful BRCA gene mutation. It aims to see whether it can control the cancer and how safe it is after prior treatment.
BeijingAges 18–75 - NCT05256745RecruitingPhase 1/Phase 2
A medicine to protect the heart during breast cancer chemotherapy
This early-phase study tests azeliragon to lower the risk of chemotherapy-related heart damage in women with early-stage breast cancer. Participants get their planned standard chemotherapy, plus the study medicine, and are monitored for safety and heart health.
Washington D.C., District of ColumbiaAges 18 years+ - NCT04767659Recruiting
Optical imaging to predict full response to breast cancer chemo
This study uses a light-based scanner (optical imaging) during neoadjuvant chemotherapy to see how your breast cancer responds and to predict whether treatment will fully clear the tumor. If you qualify, it may help researchers better match imaging patterns to treatment success.
MilanAges 18 years+ - NCT05027321Recruiting
Self-hypnosis to ease stress during breast biopsy
This study tests whether guided self-hypnosis—either by using a “mental anchor” or by a more conversational style—can reduce stress or discomfort during a breast macrobiopsy. It may help patients feel calmer during the procedure.
MarseilleAges 18 years+ - NCT04904757Recruiting
CESM contrast mammogram screening for dense breasts
This trial tests a newer kind of breast screening scan that uses a special dye (contrast) to better show breast tissue. It may help people with very dense breasts get clearer screening images.
Charlottesville, VirginiaAges 40–69 - NCT04638725Recruiting
Genetics study to find why HER2 breast cancer treatment varies
This study looks at genetic factors to understand why some people’s HER2-positive breast cancer responds better—or has more side effects—after treatment. Your info and possible past treatment history may help researchers improve how HER2 treatment is chosen and managed.
StrasbourgAges 18 years+ - NCT05071105Recruiting
Short-course radiation for early breast cancer in older women
This study looks at a brief type of radiation called SBRT given soon after starting hormone therapy for certain early breast cancers in women age 75 and older. It may help treat the cancer locally while aiming to be easier to receive than longer radiation schedules.
Rome, RomeAges 75 years+ - NCT04824014RecruitingPhase 2
PET imaging for ER+ advanced breast cancer
This trial uses a special PET scan called 4FMFES-PET to take detailed pictures of ER-positive breast cancer that has spread. It helps doctors see where the cancer is and how active it is, which may guide treatment decisions.
Sherbrooke, QuebecAges 18 years+ - NCT04680715RecruitingPhase 2
Tested radiation before and after breast surgery in older women
This Phase 2 trial looks at a specific radiation timing and technique around the time of breast-conserving surgery. It may help reduce the chance the cancer comes back in selected older patients with certain early-stage, hormone-positive, HER2-negative breast cancers.
Clermont-FerrandAges 65 years+ - NCT04254263RecruitingPhase 3
Pyrotinib after breast cancer therapy for HER2-positive early disease
This trial studies whether adding pyrotinib after standard treatment helps prevent breast cancer from coming back in people with HER2-positive early-stage breast cancer. You may be eligible if you finished chemotherapy plus trastuzumab and still had signs of cancer in the tissue removed during surgery.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT04481932RecruitingPhase 2
Trastuzumab with chemo for HER2-positive breast cancer
This Phase 2 study tests whether adding trastuzumab (a targeted antibody) given with chemo and extra drugs can better treat certain HER2-positive, locally advanced or inflammatory breast cancers. It may help by improving cancer control in people who have not had prior anti-cancer treatment for their breast cancer.
