Recruiting studies in Pennsylvania
- NCT04802759RecruitingPhase 1/Phase 2
Testing drug combinations for recurrent or advanced ER-positive breast cancer
This early-phase trial tests several combinations of cancer medicines to slow or control ER-positive breast cancer that has returned or progressed. It also checks safety and whether tumor or blood biomarkers can help match the right treatment to the right person.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04523857RecruitingPhase 2
Abemaciclib and hydroxychloroquine after breast cancer relapse risk
This Phase 2 trial tests whether abemaciclib plus hydroxychloroquine can kill tiny “leftover” cancer cells in the bone marrow after standard breast cancer treatment. It may help lower the chance of cancer coming back by targeting minimal residual disease.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04434040RecruitingPhase 2
Atezolizumab and sacituzumab to prevent breast cancer return
This trial tests two medicines after surgery and chemotherapy to help lower the risk that triple-negative breast cancer comes back. It’s for people whose cancer still showed “residual” invasive disease after neoadjuvant (before-surgery) chemotherapy, and whose blood test shows traces of tumor DNA.
Philadelphia, 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.
Doylestown, PennsylvaniaAges 18 years+ - 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+ - 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+ - NCT02945579Recruiting
Testing skipping breast surgery or radiation for top responders
This trial studies whether some people with early-stage breast cancer who respond extremely well to hormone/chemo/targeted treatment can safely skip breast surgery and/or radiation. It aims to reduce side effects without increasing cancer risk in carefully selected patients.
Pittsburgh, PennsylvaniaAges 30 years+ - NCT01042379RecruitingPhase 2
Adaptive drug trial for newly diagnosed breast cancer
This study tests personalized, changing treatment plans (given before surgery) to find better options for your specific breast tumor. You may be asked for extra breast-tissue testing to help match you with the most suitable study drug(s).
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.
Stroudsburg, PennsylvaniaAges 50–70 - NCT06923527RecruitingPhase 2
Testing ctDNA to start elacestrant in early breast cancer
This trial tests whether the drug elacestrant can help prevent recurrence in people with a type of breast cancer (ER+/HER2-) who have finished hormone therapy and have signs of cancer DNA in their blood (ctDNA positive) but no visible spread on scans.
Pittsburgh, PennsylvaniaAges 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.
Bethlehem, PennsylvaniaAges 18 years+ - NCT07332975Recruiting
Blood test for tumor DNA in early triple-negative breast cancer
This study is for people with early-stage triple-negative breast cancer (TNBC) that has not been treated yet. Researchers want to see if tracking tumor DNA in your blood can help guide treatment decisions. You would receive standard chemotherapy and surgery, plus give blood samples.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT05059444Recruiting
Blood test to catch cancer early after treatment
This study looks for signs of cancer left in the body after treatment using a simple blood test (called a liquid biopsy). It aims to see if the test can catch cancer that might come back earlier than regular scans.
Broomall, PennsylvaniaAges 18 years+ - NCT07114601RecruitingPhase 1
Study of LY4257496 for people with GRPR-positive solid tumors
This trial tests a new drug, LY4257496, in people with certain types of cancer that have a protein called GRPR on their cells. The study aims to see if the drug can help shrink tumors or slow the cancer's growth.

What taking part in a er positive 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.
