Philadelphia, PennsylvaniaAges 45–74 - NCT05867251RecruitingPhase 1/Phase 2
AVZO-021 for advanced breast and ovarian cancers
This early-stage study tests AVZO-021, a new anti-cancer medicine, in people with advanced solid tumors like specific types of breast and ovarian (or related) cancers. It’s meant to find the safest dose and look for signs the medicine can shrink tumors, especially in cancers with certain gene changes.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06500455RecruitingPhase 3
Standard vs longer radiation for brain metastases
This trial compares the usual short course of radiation therapy (one session) to a longer course (up to 5 sessions) for people with cancer that has spread to the brain. The goal is to see if the longer course works better and causes fewer side effects.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07038785Recruiting
Can trained dogs find breast cancer from breath?
This trial will see if specially trained dogs can identify breast cancer by smelling breath samples. You would give a breath sample and the dogs will be tested on how well they can detect cancer from it.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06380751RecruitingPhase 3
New targeted therapy for BRCA/PALB2-mutated HR+ breast cancer
This trial tests a new combination of targeted therapies (saruparib plus camizestrant or hormone therapy) against standard treatments for people with a specific type of advanced breast cancer. It may be a good option if you have a BRCA1, BRCA2, or PALB2 gene mutation and have not yet had treatment for your advanced disease.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05929768RecruitingPhase 3
Shorter chemo plus immunotherapy without anthracyclines for early TNBC
This Phase 3 trial tests whether a shorter course of chemotherapy plus immunotherapy can work as well as standard treatment for early-stage triple-negative breast cancer. It avoids anthracycline drugs and may help reduce exposure to those medicines if the shorter plan is effective and safe.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07100106RecruitingPhase 1/Phase 2
Study of GDC-4198 alone or with giredestrant for advanced breast cancer
This trial tests a new treatment (GDC-4198) alone or with another drug (giredestrant) compared to a standard combination (abemaciclib and giredestrant) for people with advanced hormone receptor-positive, HER2-negative breast cancer that has progressed after previous treatments.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06369285RecruitingPhase 2
Alisertib and hormone therapy for advanced breast cancer
This trial tests a new drug, alisertib, combined with hormone therapy for people with HR-positive, HER2-negative breast cancer that has spread or come back and is no longer curable. It may be an option if you've already tried at least two hormone therapies and a CDK4/6 inhibitor.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06778863RecruitingPhase 1
A study of CLSP-1025 for adults with certain solid tumors
This trial tests a new drug called CLSP-1025 for people with advanced solid tumors that have a specific change in the p53 gene (R175H). The drug targets this change to help fight the cancer.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07737951Recruiting
Tai chi for joint pain from breast cancer hormone therapy
This trial tests whether tai chi can help reduce joint pain caused by aromatase inhibitors, which are hormone therapies for breast cancer. If you have joint pain from this treatment, tai chi might be a gentle way to find relief.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07054723Recruiting
Surviving daily life after breast cancer
This study looks at how breast cancer survivors manage daily life. Researchers want to learn from people who are 40 or older and at least 5 years past their diagnosis. The goal is to better understand what helps people thrive after cancer.
Philadelphia, PennsylvaniaAges 40 years+ - NCT06876714RecruitingPhase 3
Shorter vs Longer HER2 Therapy for Breast Cancer with Complete Response
This trial compares 6 months versus 12 months of HER2-targeted therapy for people with HER2+ breast cancer who had a complete response after chemo and trastuzumab. The goal is to see if a shorter treatment is just as effective.
Philadelphia, PennsylvaniaAges 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.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06586957RecruitingPhase 1
Study of NKT3964 for advanced solid tumors
This trial is testing an experimental oral drug called NKT3964 for people with advanced solid tumors that have stopped responding to standard treatments. The drug works by blocking a protein called CDK2, which some cancers need to grow.
Philadelphia, PennsylvaniaAges 18 years+ - NCT03424005RecruitingPhase 1/Phase 2
Testing new drug combinations for advanced breast cancer
This study tests how well and how safely different combinations of cancer drugs work for people with metastatic or inoperable locally advanced breast cancer. It may help by finding a better treatment option and collecting information to guide future care.

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.
