This trial tests an experimental oral drug (NKT5097) for people with advanced solid tumors that have not responded to other treatments. It may also be an option for people with a specific type of breast cancer (HR+/HER2-). The goal is to see if the drug is safe and effective.
Boston, MassachusettsAges 18 years+ - NCT07198724RecruitingPhase 1/Phase 2
A study of elacestrant plus Enhertu for advanced breast cancer
This trial tests a new combination of two targeted drugs (elacestrant and Enhertu) for people with a specific type of advanced breast cancer (HR-positive, HER2-low or ultra-low) that did not respond to standard treatments like CDK4/6 inhibitors. The goal is to see if this combination works better than current options.
Boston, MassachusettsAges 18 years+ - NCT07222215RecruitingPhase 2
Capacitabine with or without elacestrant for ER+ breast cancer
This trial tests if adding a new oral targeted therapy (elacestrant) to standard chemotherapy (capecitabine) works better than chemotherapy alone for people with a specific type of advanced breast cancer that is hormone-sensitive (ER-positive) and has stopped responding to hormone therapy.
Boston, MassachusettsAges 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.
Boston, MassachusettsAges 18 years+ - NCT05827081RecruitingPhase 3
Ribociclib plus endocrine therapy for early breast cancer
This trial studies whether adding ribociclib to standard hormone (endocrine) therapy lowers the risk of breast cancer coming back in early-stage, hormone-receptor–positive cancer. It mainly looks at safety and how well the treatment controls cancer after surgery and (sometimes) prior hormone treatment.
Boston, MassachusettsAges 18–100 - NCT05501704RecruitingPhase 2
Testosterone-blocking therapy for male breast cancer
This Phase 2 study tests an oral treatment (called “ET”) to treat hormone-receptor–positive, HER2-negative invasive breast cancer in men. It may help shrink or control cancer without using standard cancer treatments first.
Boston, MassachusettsAges 18 years+ - NCT06401421Recruiting
Blood test for tumor DNA after breast cancer chemo
This study tests a new blood test to see if it can find tiny bits of tumor DNA after chemotherapy. If you have a larger or higher-risk breast cancer and are getting chemotherapy before surgery, you may join. The test could help doctors know if your cancer is gone or if more treatment is needed.
Burlington, MassachusettsAges 18 years+ - NCT04468061RecruitingPhase 2
Study chemo drug plus immunotherapy for metastatic triple-negative breast cancer
This trial tests sacituzumab govitecan (an antibody-drug medicine) with or without pembrolizumab (an immune-system therapy) in people with metastatic triple-negative breast cancer. It may help by shrinking tumors and improving immune control, especially for patients with specific tumor marker results.
Foxborough, MassachusettsAges 18 years+ - NCT06324357RecruitingPhase 1/Phase 2
Zongertinib for HER2-positive cancers that have spread
This trial tests a new pill called zongertinib, alone or with other drugs, for people with HER2-positive cancers (like breast, stomach, or colorectal cancer) that have spread and are no longer responding to standard treatments. The goal is to find the best dose and see if it can help shrink tumors or slow the disease.
Boston, MassachusettsAges 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.
Lowell, MassachusettsAges 50–70 - NCT03990896RecruitingPhase 2
Talazoparib for metastatic breast cancer with BRCA body DNA changes
This Phase 2 trial tests talazoparib, a targeted cancer medicine, in people with metastatic breast cancer that has a harmful BRCA1 or BRCA2 mutation found in tumor DNA circulating in the blood. If you qualify, the goal is to see how well this treatment works when the mutation is detected this specific way.
Boston, MassachusettsAges 18 years+ - NCT05696626RecruitingPhase 3
Test a new pill plus abemaciclib versus standard therapy
This Phase 3 study compares lasofoxifene plus abemaciclib versus fulvestrant plus abemaciclib for ER-positive, HER2-negative breast cancer that has an ESR1 mutation. It looks for better tumor control in people whose cancer has progressed on hormone therapy (an aromatase inhibitor) and who meet specific safety and testing requirements.
Boston, MassachusettsAges 18 years+ - NCT04862663RecruitingPhase 3
Capivasertib plus hormone therapy for HR+ breast cancer after progression
This Phase 3 trial studies capivasertib (a targeted pill) plus fulvestrant (a hormone injection) together with a CDK4/6 inhibitor to treat HR+ / HER2- advanced breast cancer that has returned or grown despite earlier hormone therapy. It may help by blocking growth signals linked to cancer cell survival.
Boston, MassachusettsAges 18–99 - 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.
Boston, MassachusettsAges 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.
Beverly, MassachusettsAges 18–60 - NCT07173751RecruitingPhase 3
Pumitamig for advanced triple-negative breast cancer
This study tests a new drug called pumitamig for people with a type of breast cancer that is triple-negative or has very low hormone receptors and has come back or spread. It aims to see if pumitamig works better than standard treatment and how safe it is for people who cannot get PD(L)-1 immunotherapy with chemo.
Burlington, MassachusettsAges 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.

What taking part in a her2 + 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.
