Recruiting studies in Pennsylvania
- NCT04585750RecruitingPhase 1/Phase 2
Study drug for TP53 Y220C-mutated advanced cancers
This early-phase study tests PC14586 (rezatapopt) in people with advanced or metastatic solid cancers that carry a specific TP53 mutation called Y220C. It mainly looks at safety and how well the treatment may work, sometimes combined with pembrolizumab.
Philadelphia, PennsylvaniaAges 12 years+ - NCT04841148RecruitingPhase 2
Avelumab or hydroxychloroquine to target hidden breast cancer
This Phase 2 trial tests whether adding different medicines—either avelumab or hydroxychloroquine, with or without palbociclib—can eliminate dormant “leftover” breast cancer cells. It’s meant for people with hormone-receptor–positive breast cancer who have no visible cancer now, but still have detectable dormant cells in the bone marrow.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04886531RecruitingPhase 2
Pre-surgery neratinib plus hormone therapy with trastuzumab
This study tests whether a pre-surgery treatment plan that adds neratinib to hormone therapy and trastuzumab can shrink HER2-positive, ER-positive breast cancer before surgery. It may help patients by improving how much cancer is eliminated at the time of surgery.
Hershey, 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+ - NCT05372640RecruitingPhase 1
Drug combo trial for rare cancers with shared NUT features
This Phase 1 trial tests the safety and early signs of effectiveness of combining two anti-cancer drugs (ZEN003694 and abemaciclib) in teens and adults with metastatic or unresectable NUT carcinoma, breast cancer, and other solid tumors. It may help by finding a safer dose and whether the drug combination can shrink or control tumors that do not respond to standard treatments.
Pittsburgh, PennsylvaniaAges 12 years+ - NCT05396612Recruiting
Studying the immune response in non-cancer-spread breast surgery
This study looks at how your immune system changes while you receive standard breast cancer treatment around the time of surgery. The goal is to learn why some people respond better than others, which could help future treatment choices.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05455619RecruitingPhase 1/Phase 2
Targeted drugs for PI3K-altered, HR+/HER2- breast cancer
This Phase 1/2 trial tests how well a combination of targeted medicines works for advanced or returning HR+/HER2- breast cancer that has a PI3K pathway change (such as PIK3CA, PTEN, or AKT1). It may help by blocking growth signals in the cancer and is especially for people whose cancer has progressed after hormone therapy and a CDK4/6 inhibitor.
Hershey, PennsylvaniaAges 18 years+ - NCT05534438RecruitingPhase 2
Tested targeted radiation plus usual drug treatment in metastatic breast cancer
This Phase 2 study tests whether adding a very focused type of radiation to standard drug treatment can better control metastatic breast cancer. It is for people whose cancer is only progressing in one spot, seen on a PET scan.
Allentown, PennsylvaniaAges 18 years+ - NCT05579366RecruitingPhase 1/Phase 2
Study drug for advanced ovarian and other solid cancers
This Phase 1/2 trial studies Rinatabart Sesutecan to treat advanced cancers, with special focus on certain ovarian cancer types. It’s meant for people whose cancer has come back or has not responded to prior treatments.
Doylestown, PennsylvaniaAges 18 years+ - NCT05659797RecruitingEarly Phase 1
PET scan test for new ER-positive breast cancer
This early study tests a special PET scan (a type of imaging) to look at newly diagnosed ER-positive breast cancer. The goal is to see how well the scan can detect and measure cancer, which may help guide care.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05748834RecruitingPhase 2
Tucatinib plus Doxil for HER2-positive metastatic breast cancer
This Phase 2 study tests tucatinib (a HER2-targeted pill) plus Doxil (a chemotherapy medicine) to slow or shrink HER2-positive metastatic breast cancer that has been treated before. It may help by targeting HER2 cancer cells more effectively than past treatments alone.
Bensalem, PennsylvaniaAges 18 years+ - NCT05774951RecruitingPhase 3
Camizestrant for hormone-positive, HER2-negative early breast cancer
This trial tests camizestrant, a medicine that blocks estrogen signaling, to help prevent hormone-positive, HER2-negative early breast cancer from coming back. You may be eligible if your cancer has higher- or intermediate-risk features and you already completed at least 2 years of hormone therapy.
Clairton, PennsylvaniaAges 18–130 - 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+ - 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+ - NCT05964504Recruiting
Registry study for metastatic lobular breast cancer
This study collects health information from adults with invasive lobular breast cancer that has spread (metastatic) to help researchers understand factors linked to survival. Joining may help build better knowledge for future treatments and care planning.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06016738RecruitingPhase 3
Palazestrant vs standard therapy for advanced breast cancer
This trial compares a new oral drug, palazestrant (OP-1250), to standard hormone therapies for people with ER+/HER2- advanced breast cancer that has worsened after prior hormone therapy. It tests whether palazestrant can better control the cancer.
Sayre, PennsylvaniaAges 18 years+ - NCT06105749Recruiting
Biennial contrast mammography in women with past breast cancer
This trial tests if contrast-enhanced mammography (CEM) every two years works as well as routine mammograms for women who have had breast cancer. It aims to find a better way to screen for new cancers in this group.
Bethel Park, PennsylvaniaAges 30–79 - NCT06112613Recruiting
Mobile health to help with breast cancer pill-taking
This study uses text messages to help people with metastatic breast cancer remember to take their daily pills and asks about any missed doses. It aims to improve how well patients stick to their CDK4/6 inhibitor medication.
Scranton, PennsylvaniaAges 18 years+ - NCT06115486Recruiting
Exercise to improve muscle after breast cancer treatment
This trial tests whether a structured exercise program (called EXERT-BCH) can help improve muscle mass in women who have finished breast cancer treatment. It involves group resistance training sessions and is designed to support recovery and strength.
Pittsburgh, PennsylvaniaAges 20–89 - 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+ - NCT06512350Recruiting
Breath test for breast cancer patterns
This study is testing whether a simple breath test can help find patterns linked to breast cancer. If you are scheduled for a breast biopsy or MRI, you may be eligible to participate.
Pittsburgh, PennsylvaniaAges 40–74 - 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.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT06858449Recruiting
Exercise and protein during chemo for breast cancer
This study tests whether adding resistance training (like lifting weights) along with a protein shake after workouts can help women with breast cancer maintain muscle and bone health while they receive chemotherapy before surgery.
Pittsburgh, PennsylvaniaAges 20–89 - 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.

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.
