Philadelphia, PennsylvaniaAges 18 years+ - NCT04959474Recruiting
Pre-surgery radiation study with or without calorie restriction
This trial looks at whether a planned calorie-reduction diet before surgery can change how early breast cancer responds to a short course of radiation. It may help people understand if diet could improve outcomes alongside standard pre-surgery treatment.
Philadelphia, PennsylvaniaAges 40 years+ - NCT06492616RecruitingPhase 3
Elacestrant vs standard hormone therapy for high-risk early breast cancer
This trial tests a new hormone therapy pill (elacestrant) against standard hormone therapy for people with a common type of early breast cancer (ER+, HER2-) that has a higher chance of returning. You may qualify if you've already been on hormone therapy for 2 to 5 years and want to see if a different pill works better.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07454499Recruiting
Symptom monitoring and health for women on hormone therapy for breast cancer

Philadelphia, PennsylvaniaAges 18 years+ - NCT07319195RecruitingEarly Phase 1
Study of a new drug injected into tumors for breast cancer
This trial tests a drug called mitazalimab injected directly into the tumor for patients with early-stage or recurrent breast cancer who are scheduled for surgery. The goal is to see if this approach can help the immune system fight the cancer before surgery.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07182149RecruitingPhase 1
Testing a new drug for advanced solid tumors
This trial tests a new drug called NRM-823 for people with several types of advanced cancer that have stopped responding to standard treatments. The goal is to see if the drug is safe and how well it works.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07140172Recruiting
Radiation or surgery for node-positive breast cancer
This trial compares two treatments for people with breast cancer that has spread to the lymph nodes: radiation therapy to the armpit or surgery to remove the lymph nodes. The goal is to see which approach works best after a tailored surgery to remove the most suspicious lymph nodes.
Philadelphia, 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 - NCT06395519RecruitingPhase 1/Phase 2
Study of ETX-19477 for advanced solid tumors
This trial tests an experimental drug called ETX-19477 for people with advanced solid tumors that have stopped responding to other treatments. It aims to see if the drug is safe and effective, especially for those with certain genetic changes (BRCA2 mutations).
Philadelphia, PennsylvaniaAges 18 years+ - NCT06393374RecruitingPhase 3
Study of a new drug combination for residual TNBC after initial treatment
This trial tests a new combination of two drugs (sacituzumab tirumotecan and pembrolizumab) compared to standard chemotherapy for people with triple-negative breast cancer that did not fully respond to initial treatment. It aims to see if this combination helps prevent cancer from coming back.
Philadelphia, PennsylvaniaAges 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.
Philadelphia, PennsylvaniaAges 18–60 - NCT07067788Recruiting
Comparing a new imaging method for breast calcifications
This study tests a new imaging technique to better see suspicious calcifications found during a mammogram. If you have these calcifications, this might help doctors learn more about them.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05126290Recruiting
Study for CTNNA1 gene family members
This study looks at people who carry a specific “loss-of-function” CTNNA1 gene change—or who are closely related to someone who does. It’s designed to better understand this genetic risk in families and may help guide future care and monitoring.
Philadelphia, PennsylvaniaAges 18 years+ - NCT02732171Recruiting
Blood and bone marrow tests to track breast cancer return
This trial checks whether specific “surveillance” markers (measured from blood and bone marrow) can help predict if breast cancer comes back after standard treatments. It may help doctors monitor you more accurately and earlier if recurrence risk is high.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05059444Recruiting
Blood test study to watch for cancer coming back
This study looks at whether blood tests can detect signs that cancer may return after curative-intent treatment. You would have blood drawn around your usual follow-up visits for up to 5 years, and your de-identified health data would be shared with study investigators.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06757634RecruitingPhase 3
A study of gedatolisib for first-line advanced breast cancer
This trial tests a new targeted therapy called gedatolisib for people with HR-positive, HER2-negative advanced breast cancer who have not yet received treatment for metastatic disease. It aims to see if adding this drug to standard hormone therapy can help control the cancer longer.
Philadelphia, PennsylvaniaAges 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.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05978141Recruiting
T-cell lymphoma registry study
This study creates a registry for people with certain T-cell or NK-cell lymphomas. It collects health information and tumor samples to learn more about these diseases and improve future treatments.

Study of new drugs for HR+/HER2- advanced breast cancer
This trial tests two new drugs (sacituzumab tirumotecan and pembrolizumab) against standard treatments for a type of advanced breast cancer that is hormone receptor positive and HER2 negative. It's for people whose cancer has worsened despite hormone therapy with a CDK4/6 inhibitor.
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 - NCT06332131Enrolling by invitation
Heart blood vessel effects of immunotherapy in breast and lung cancer
This trial studies whether immunotherapy drugs (called immune checkpoint inhibitors) affect the small blood vessels of the heart. If you have breast cancer or lung cancer and are starting a specific treatment plan, you may be asked to have a special heart scan before and during therapy.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04852887RecruitingPhase 3
Testing shorter breast radiation after low-risk hormone breast cancer
This Phase 3 trial studies whether “less intense” radiation can work as well as standard radiation for certain early-stage hormone receptor–positive, HER2-negative breast cancers that have a low Oncotype DX score. It may help reduce treatment burden while keeping cancer control strong.
Philadelphia, PennsylvaniaAges 50–70 - NCT06435429RecruitingPhase 3
Zanidatamab vs trastuzumab for HER2+ breast cancer
This study compares a new drug called zanidatamab against trastuzumab (Herceptin), both given with a chemotherapy of your doctor's choice. It is for people with HER2-positive breast cancer that has spread and who have already tried T-DXd treatment.
