Washington D.C., District of ColumbiaAges 18 years+ - NCT06892275Recruiting
Helping high-risk women decide about breast MRI
This study tests a decision aid to help women at high risk for breast cancer decide whether to get a screening MRI. It is designed for Black and Latina women who have had a normal mammogram in the past year.
Washington D.C., District of ColumbiaAges 18–74 - NCT07062965RecruitingPhase 3
PF-07248144 with fulvestrant for HR+ HER2- advanced breast cancer
This trial tests a new study medicine (PF-07248144) combined with fulvestrant in people with a certain type of advanced breast cancer (HR-positive, HER2-negative) that has worsened after previous treatments. It may be an option if you've already tried a CDK4/6 inhibitor and endocrine therapy.
Washington D.C., District of ColumbiaAges 18 years+ - NCT05879926RecruitingPhase 3
Testing chemo after hormone therapy in premenopausal early breast cancer
This Phase 3 trial checks whether adding chemotherapy after standard hormone-blocking treatment works better for some premenopausal women with early-stage, ER-positive, HER2-negative breast cancer. It targets patients with limited lymph node spread and a lower-to-intermediate tumor “recurrence” risk score.
Washington D.C., District of ColumbiaAges 18–60 - NCT05633654RecruitingPhase 3
Test drug combo versus standard care for triple-negative breast cancer
This trial tests a cancer antibody-drug combination plus pembrolizumab (immunotherapy) versus standard treatment. It’s for people with triple-negative breast cancer that still has invasive disease in the breast or lymph nodes after surgery and chemotherapy before surgery.
Washington D.C., District of ColumbiaAges 18 years+ - NCT07174336RecruitingPhase 3
Testing Tersolisib with other treatments for advanced breast cancer
This trial tests a new study drug called Tersolisib combined with other anti-cancer treatments for people with advanced breast cancer that has a specific gene change (PIK3CA). The goal is to see if the combination can help shrink or slow the cancer.
Washington D.C., District of ColumbiaAges 18 years+ - NCT06500481RecruitingPhase 3
Proton vs standard radiation for cancer spread to brain/spine lining
This trial compares a newer type of radiation (proton therapy) to standard radiation for people whose breast or lung cancer has spread to the lining of the brain and spinal cord. It aims to see if proton therapy can better control the disease while causing fewer side effects.
Washington D.C., District of ColumbiaAges 18 years+ - NCT06841354RecruitingPhase 3
Sac-TMT alone or with pembrolizumab for advanced triple-negative breast cancer
This trial tests a new drug, Sac-TMT, given alone or with an immunotherapy drug (pembrolizumab) for people with advanced triple-negative breast cancer who have not yet received any treatment for advanced disease. The goal is to see if this combination can shrink tumors or slow the cancer's growth.
Washington D.C., District of ColumbiaAges 18 years+ - NCT07357597RecruitingPhase 4
Preventing mouth sores during breast or lung cancer treatment
This trial tests whether a steroid mouthwash can prevent mouth sores caused by the drug Datopotamab Deruxtecan (Dato-DXd). It is for people with certain types of advanced breast cancer or lung cancer who are about to start Dato-DXd for the first time.
Washington D.C., District of ColumbiaAges 18 years+ - NCT05232916RecruitingPhase 3
Vaccine for HER2-positive breast cancer after standard treatment

What taking part in a breast cancer study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
