Orange, CaliforniaAges 18 years+ - NCT07436078Recruiting
Genetic testing study for African American cancer survivors
This study offers genetic testing and counseling to African American cancer survivors. It aims to see if a culturally tailored approach helps more people understand their cancer risk and get the testing they need.
Detroit, MichiganAges 20–79 - NCT06516289RecruitingPhase 2
Neoadjuvant treatment for BRCA-mutated HER2-negative breast cancer
This trial tests a combination of two oral medications (HRS-1167 and famitinib) with or without an immunotherapy drug (camrelizumab) before surgery for women with a BRCA gene mutation and HER2-negative breast cancer. It aims to see if these drugs can shrink tumors before surgery.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT06240195Recruiting
Study of sacituzumab govitecan for advanced triple-negative breast cancer
This study is testing a drug called sacituzumab govitecan (SG) for people with advanced triple-negative breast cancer who have already had other treatments. The goal is to see how well the drug works and what side effects it causes, using your tumor samples to look for clues (biomarkers).
Rome, RomeAges 18 years+ - NCT07214532Recruiting
Using a blood test to guide breast cancer therapy
This study tests whether a blood test can help decide when to start additional hormone-blocking therapy for early-stage breast cancer. It aims to see if starting therapy only when the test detects cancer DNA is as effective as giving it to everyone.
Phoenix, ArizonaAges 18 years+ - NCT02306096Recruiting
Study of breast cancer genes using blood or tumor samples
This trial looks at the genes in breast cancer to better understand the disease. It may help researchers find patterns that could improve future breast cancer diagnosis or treatment.
BoråsAges Any age - NCT06910072Enrolling by invitationPhase 2/Phase 3
Chemo and immunotherapy before surgery for triple-negative breast cancer
This trial tests a combination of chemotherapy and two immunotherapy drugs given before surgery for women and men with triple-negative breast cancer. The goal is to see if this approach helps shrink or eliminate the tumor before surgery.
BeijingAges 18–75 - NCT07292246Recruiting
HandX-assisted endoscopic mastectomy study for breast cancer
This trial tests a new, less invasive way to remove breast tissue using a small camera (endoscope) with a device called HandX. It's for women who need a mastectomy for early-stage breast cancer, DCIS, or to reduce high risk, and aims to see if it's safe and works well.
Glyfada, AtticaAges 18 years+ - NCT07357311Recruiting
Screening for Fear of Cancer Recurrence
This study aims to help people with breast or lung cancer who worry about their cancer coming back. You will answer questionnaires about your fears, so the care team can better support you.

Ribociclib for breast cancer with leftover disease after chemo
This trial tests ribociclib, a targeted therapy, for women with hormone receptor-positive, HER2-negative breast cancer who still have cancer cells in the breast or lymph nodes after initial chemotherapy. It aims to reduce the chance of cancer coming back.
Zhanjiang, GuangdongAges 18 years+ - NCT07260188Recruiting
Breast cancer organoids from patients before chemo
This study collects tumor tissue from breast cancer patients before they start chemotherapy to grow miniature versions of their tumors (organoids) in the lab. The goal is to understand how each tumor responds to treatment, which may help personalize future therapies.
Pavia, PVAges 18 years+ - NCT07262138Recruiting
Active monitoring for older women with early breast cancer
This trial studies whether active monitoring (watchful waiting) can be a safe option instead of immediate surgery or other treatments for women 70 and older who have a small, slow-growing type of breast cancer. If you join, you will not have surgery or other treatments right away, but your cancer will be closely watched.
Pittsburgh, PennsylvaniaAges 70 years+ - NCT04892693RecruitingPhase 2
Talazoparib for advanced breast cancer with DNA repair defects
This trial studies talazoparib (a targeted pill) in people with advanced breast cancer whose tumors have problems repairing certain DNA damage. If your tumor has these specific “DNA repair” defects, the medicine may work better and stop the cancer from growing.
SeoulAges 19 years+ - NCT07173868Recruiting
PET scans for advanced breast cancer treatment planning
This trial tests whether a special PET scan (FDG PET-CT) can better track how well treatment is working for people with advanced breast cancer. It may help doctors choose the best therapy and monitor response over time.
