Recruiting studies in Pennsylvania
- NCT07391774RecruitingPhase 3
Hormone therapy with or without chemo for early breast cancer
This trial tests whether skipping chemotherapy and using only hormone therapy with a drug called ribociclib works as well as chemotherapy followed by hormone therapy with ribociclib for certain early breast cancers that have a low risk of coming back.
Philadelphia, PennsylvaniaAges 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).
Allentown, PennsylvaniaAges 18 years+ - NCT06105749Recruiting
Biennial contrast-enhanced mammogram for breast cancer survivors
This study tests whether getting a contrast-enhanced mammogram (CEM) every two years is effective for detecting breast cancer in women who have had breast cancer before. If you qualify, you will receive CEM instead of a standard mammogram to see if it helps find cancer earlier.
Bethel Park, PennsylvaniaAges 30–79 - NCT05919108RecruitingPhase 2
Neratinib before surgery for HER2-mutated invasive lobular breast cancer
This Phase 2 trial tests neratinib given before surgery to treat stage I–III invasive lobular breast cancer that has a specific HER2 mutation and is hormone-receptor positive. It may help shrink the tumor and improve control of cancer before and after surgery.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT06888388Recruiting
Safety of nipple-sparing mastectomy for women with high-risk genes
This study looks at the long-term safety of a type of breast surgery (nipple-sparing mastectomy) in women who carry certain inherited gene changes (BRCA1, BRCA2, PALB2, TP53, CDH1, or PTEN) that increase their risk of breast cancer. The goal is to understand how safe this surgery is over time for these women.
Philadelphia, PennsylvaniaAges 18–90 - NCT07085767RecruitingPhase 3
Palazestrant and ribociclib for first-line advanced breast cancer
This trial tests a new drug (palazestrant) combined with ribociclib for people with a common type of advanced breast cancer that is estrogen receptor-positive and HER2-negative. You may qualify if you haven't had treatment for advanced disease and your cancer has either just been found or came back long after completing hormone therapy.
Horsham, PennsylvaniaAges 18 years+ - NCT07739563Recruiting
Exercise for heart health after breast cancer
This study compares two types of exercise programs for women who have completed breast cancer treatment. It aims to see which type of training helps improve heart health and fitness.
Pittsburgh, PennsylvaniaAges 20–89 - NCT05327608RecruitingPhase 2
Time-restricted eating during breast cancer chemotherapy
This study is testing whether time-restricted eating (confining all meals to a specific window each day) can improve the response to chemotherapy in women with newly diagnosed breast cancer. Participants will follow this eating pattern for 16 weeks while receiving their standard chemotherapy, and the researchers will monitor how the tumor shrinks.
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.
Hershey, PennsylvaniaAges 18 years+ - NCT03723928Recruiting
Blood test–guided monitoring for metastatic breast cancer treatment
This study checks whether specific blood “tumor marker” levels can help monitor how hormone receptor–positive, HER2-negative metastatic breast cancer responds to first-line therapy. It uses regular blood tests (and sometimes scans) to see if this marker-based monitoring is useful and reliable.
Scranton, PennsylvaniaAges 18 years+ - NCT06065748RecruitingPhase 3
New hormone therapy for advanced breast cancer after prior treatment
This trial tests a new oral hormone therapy, giredestrant, against a standard hormone therapy (fulvestrant) when both are given with a CDK4/6 inhibitor. It is for people with advanced ER-positive, HER2-negative breast cancer that has come back after initial hormone therapy, and who have not yet had other treatments for advanced disease.
Bensalem, PennsylvaniaAges 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.
Hershey, 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.
Allentown, PennsylvaniaAges 18 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.
Beaver, 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.
Gettysburg, PennsylvaniaAges 18 years+ - NCT05334069Recruiting
Blood test study for early cancer detection in patients
This study collects blood from people with cancer and people without cancer (or with possible cancer) to test whether new blood tests can detect cancer earlier. Your blood samples help researchers evaluate how well these tests work.
Allentown, PennsylvaniaAges 40–75 - NCT06790693RecruitingPhase 3
Inavolisib plus hormone therapy for advanced breast cancer
This trial tests a new targeted therapy, inavolisib, combined with standard hormone therapy and a CDK4/6 inhibitor for people with a specific genetic mutation (PIK3CA) in their hormone receptor-positive, HER2-negative advanced breast cancer that has not been treated before. It compares this combination to a placebo plus the same standard treatments.
Pittsburgh, PennsylvaniaAges 18 years+ - 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.
Carlisle, PennsylvaniaAges 18–50 - 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.
Horsham, PennsylvaniaAges 18 years+ - NCT05535192Recruiting
Telehealth strength exercise to help older women during breast cancer chemo
This study tests whether a supervised at-home (telehealth) strength exercise program can help older women stay strong and keep their chemotherapy on schedule. It’s meant for women who are starting chemotherapy for breast cancer with the goal of cure.
Pittsburgh, PennsylvaniaAges 65 years+ - NCT07055854RecruitingPhase 1
Mindfulness program for better sex after breast or gynecologic cancer
This study tests an online mindfulness program to help women with breast or gynecologic cancer improve their sexual health. The program is designed for survivors who have concerns about their sex life after treatment.
Philadelphia, PennsylvaniaAges 18 years+ - NCT03452774Recruiting
AI matches your cancer tests to possible treatment trials
This trial uses an AI system to help match people with certain cancer types and specific tumor test results (like gene or protein markers) to relevant clinical trials. It may help you and your doctor find studies that fit your cancer biology faster.
Philadelphia, PennsylvaniaAges Any age - NCT03606967RecruitingPhase 2
Individualized vaccine added to standard treatment for metastatic triple-negative breast cancer
This Phase 2 trial tests whether adding a personalized cancer vaccine to durvalumab (an immunotherapy), tremelimumab (another immunotherapy), and chemotherapy can improve outcomes for people with metastatic triple-negative breast cancer. It may help your immune system recognize your specific tumor features.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT03808337RecruitingPhase 2
SBRT radiation plus standard treatment for spread cancer
This trial looks at adding a focused radiation treatment called SBRT to standard care for cancers that have spread to a limited number of spots. It aims to control those spread-out tumors while still using the usual cancer treatment plan.

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.
