Study of BGB-43395 alone or with other drugs for advanced solid tumors
This study tests a new drug called BGB-43395 alone or with other treatments for advanced solid tumors, especially breast cancer. The goal is to find the best dose and see how well it works. It may be an option if your cancer has not responded to other treatments.
Denver, ColoradoAges 18 years+ - NCT04553770RecruitingPhase 2
Trastuzumab deruxtecan with or without anastrozole for early breast cancer
This Phase 2 study tests whether trastuzumab deruxtecan alone or combined with anastrozole can control early-stage breast cancer that is HER2-low and hormone-receptor positive. It aims to improve outcomes after initial surgical treatment by targeting cancer cells that may have low levels of HER2.

Study patterns of ribociclib response and resistance in breast cancer
This trial looks at how well ribociclib works and why it may stop working over time in people with advanced, hormone-receptor–positive, HER2-negative breast cancer. It also analyzes blood and tissue samples to help researchers understand resistance patterns and improve future treatment decisions.
Erlangen, BavariaAges 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+ - NCT04585750RecruitingPhase 1/Phase 2
Studying a new drug for cancers with a specific TP53 change
This trial tests a new drug (rezatapopt) for people with advanced cancers that have a specific change in the TP53 gene, called Y220C. The drug is designed to target this change and may slow or stop cancer growth. Some participants may also receive an immunotherapy drug called pembrolizumab (Keytruda).
Irvine, CaliforniaAges 12 years+ - NCT07741968Recruiting
Online program to ease fear of cancer returning
This study tests an online program designed to help women with advanced or certain types of breast or gynecologic cancer manage their fear of the disease progressing or returning. The program aims to reduce anxiety and improve quality of life.
Arcadia, CaliforniaAges 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+ - NCT07844473Recruiting
Magtrace dye to guide surgery for early breast cancer
This trial tests using a special dye called Magtrace to help surgeons find and remove the cancer and check nearby lymph nodes during breast-conserving surgery. It might help make the surgery more precise and avoid extra procedures.
MadinahAges 18 years+ - NCT06439693RecruitingPhase 2
Sequential therapy for newly diagnosed HER2+ breast cancer that has spread
This trial tests a sequence of targeted therapies for people newly diagnosed with HER2-positive breast cancer that has spread to other parts of the body. The goal is to find a treatment plan that can potentially cure the cancer.
Boston, MassachusettsAges 18 years+ - NCT06297265Recruiting
Gentle breast massage after lumpectomy for breast cancer
This trial studies whether a special gentle massage technique (manual lymphatic drainage) can help women who have had breast-conserving surgery and will receive whole breast radiation. The goal is to see if it reduces side effects and improves recovery.
Los Angeles, CaliforniaAges 18 years+ - NCT06184750RecruitingPhase 2
Finding the best tamoxifen dose to lower breast cancer risk
This trial tests different doses of tamoxifen to find the best one for lowering breast cancer risk in premenopausal women. It aims to see if a lower dose works as well as the standard dose with fewer side effects.
Tucson, ArizonaAges 18–55 - NCT06179303RecruitingPhase 2
Imaging to predict response to abemaciclib for advanced breast cancer
This trial tests if a special PET scan can predict how well the drug abemaciclib works for people with advanced hormone receptor-positive, HER2-negative breast cancer. If you qualify, you would receive abemaciclib and have imaging scans to see if your cancer responds.
St Louis, MissouriAges 18 years+ - NCT06954831RecruitingPhase 2
Short-course radiation for early-stage breast cancer
This trial tests a shorter, more intense radiation schedule for people with stage I-III breast cancer after lumpectomy. It aims to find if giving a higher daily dose over fewer sessions is safe and effective.
Arcadia, CaliforniaAges 40 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.
Atlanta, GeorgiaAges 18 years+ - NCT05677802Recruiting
Stress-reduction program for newly diagnosed triple-negative breast cancer
This study tests whether a structured stress-reduction program can help people with newly diagnosed triple-negative breast cancer (stages I–III). The goal is to see if the program is practical and beneficial for patients during treatment.
Cleveland, OhioAges 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.
Basking Ridge, New JerseyAges 18 years+ - NCT05464810RecruitingEarly Phase 1
Letrozole with or without a cholesterol drug for early breast cancer
This early-phase study tests whether adding simvastatin to letrozole can improve outcomes in people with stage I–III breast cancer that grows with hormone signals (hormone receptor positive) and does not have HER2. It looks mainly at whether the approach is safe and useful for this specific breast cancer type.
Atlanta, GeorgiaAges 18 years+ - NCT07122713Recruiting

Breast cancer antibody-drug conjugate treatment registry
This study tracks how well antibody-drug conjugates (ADCs) work for breast cancer that has spread. You may join if you are about to start your first or second ADC for hormone receptor-positive/HER2-negative or triple-negative breast cancer.
San Francisco, CaliforniaAges 18 years+ - NCT04517838Recruiting

- How do I know if I qualify for a breast trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a breast trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
