Recruiting studies near Washington, D.C.
- NCT04389281RecruitingPhase 1
X-ray light-activated therapy for hard-to-treat skin tumors
This early-phase study tests an X-ray–activated medicine that is delivered directly into selected tumors to help control cancer that has not responded to standard treatments. If the injected area can be treated safely, it may shrink or slow the tumor and improve local control.
Washington D.C., District of ColumbiaAges 18 years+ - NCT05467891RecruitingPhase 2
Ribociclib plus hormone therapy for recurrent breast cancer
This trial tests whether adding ribociclib (a targeted pill) to hormone therapy can control breast cancer that has come back in the breast area or nearby lymph nodes/chest wall. It targets hormone-receptor–positive and HER2-negative tumors to help slow disease after local treatment.
Washington D.C., District of ColumbiaAges 18 years+ - NCT07310420RecruitingPhase 1
Evaluating ovarian suppression with ZOLADEX in premenopausal breast cancer
This trial tests a medication (ZOLADEX) to suppress ovarian function in premenopausal women with hormone receptor-positive breast cancer, either early-stage or advanced. The goal is to see how well it works and how safe it is.
Washington D.C., District of ColumbiaAges 18–55 - NCT04852887RecruitingPhase 3
Testing shorter breast radiation after low-risk hormone breast cancer

Washington D.C., District of ColumbiaAges 18 years+ - NCT05812807RecruitingPhase 3
Pembrolizumab versus monitoring after triple-negative breast cancer response
This trial checks whether giving pembrolizumab (an immunotherapy) after surgery helps people with triple-negative breast cancer reduce the chance of the cancer coming back, compared with close monitoring only. It’s for patients who had no remaining invasive cancer after neoadjuvant chemotherapy plus pembrolizumab.
Washington D.C., District of ColumbiaAges 18 years+ - NCT06058377RecruitingPhase 3
Adding immunotherapy to chemo for stage II-III breast cancer
This trial tests whether adding the immunotherapy drug durvalumab to standard chemotherapy works better than chemo alone for people with hormone receptor positive, HER2 negative breast cancer that is stage II or III and has a high-risk genetic score (MammaPrint High Risk 2).
Washington D.C., District of ColumbiaAges 18 years+ - NCT05983432RecruitingPhase 1
Study of BL-B01D1 for advanced lung and other solid tumors
This trial tests an experimental drug called BL-B01D1 for people with several types of advanced solid tumors, especially non-small cell lung cancer and breast cancer. It's designed for those whose cancer has continued to grow after standard treatments.
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+ - 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+ - 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 - NCT07228000Recruiting

Washington D.C., District of ColumbiaAges 18 years+ - 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+ - NCT05827081RecruitingPhase 3
Ribociclib plus endocrine therapy for early breast cancer
This trial studies whether adding ribociclib to standard hormone (endocrine) therapy lowers the risk of breast cancer coming back in early-stage, hormone-receptor–positive cancer. It mainly looks at safety and how well the treatment controls cancer after surgery and (sometimes) prior hormone treatment.
Washington D.C., District of ColumbiaAges 18–100 - 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.
