Recruiting studies
- NCT07137416RecruitingPhase 1
Testing a new combination of cancer drugs for HER2-positive tumors and breast cancer
This trial tests the safety of combining two drugs, CX-5461 (Pidnarulex) and Trastuzumab Deruxtecan (T-DXd), in people with HER2-positive solid tumors or certain types of breast cancer. If you have advanced cancer that hasn't responded to other treatments, this study may be an option.
Boston, MassachusettsAges 18 years+ - NCT07132749Enrolling by invitation
NEPA for nausea prevention during T-DXd in advanced HER2+ or HER2-low breast cancer
This trial tests whether the anti-nausea combination NEPA (netupitant and palonosetron) can prevent nausea and vomiting caused by the targeted therapy T-DXd in people with advanced HER2-positive or HER2-low breast cancer. It may help you if you are about to start T-DXd for the first time and want to manage treatment side effects.
Seoul, Gangnam-guAges 19 years+ - NCT07117864Recruiting
T-DXd with brain radiation for HER2+ breast cancer
This trial tests a new combination of a targeted drug (T-DXd) with brain radiation for women with breast cancer that has spread to the brain and is HER2-positive or HER2-low. The goal is to see if this approach is safe and works better than radiation alone.
Beijing, Beijing MunicipalityAges 18–75 - NCT07112053RecruitingPhase 2
Vaccine with hormone therapy or chemo for advanced breast cancer
This trial tests a vaccine (STEMVAC) given with your standard hormone therapy or chemotherapy. It is for people with advanced hormone receptor-positive, HER2-negative breast cancer who are already on certain treatments. The goal is to see if adding the vaccine can help control the cancer better.

A new imaging test for people on HER2 cancer therapy
This study tests a new imaging drug called [68Ga]Ga-ABY-025 to see how well it shows HER2-positive tumors in people who are about to start or have just started HER2-targeted cancer therapy. It may help doctors see if the treatment is working.
Nashville, TennesseeAges 18 years+ - NCT06830382Recruiting
HER2-PET scan for metastatic breast cancer treatment
This trial uses a special PET scan (HER2-PET) to see if a targeted drug (trastuzumab deruxtecan) works better for your type of metastatic breast cancer. The goal is to match the treatment to how much HER2 protein your tumors show.
SolnaAges 18 years+ - NCT06732336RecruitingPhase 1/Phase 2
PET scan for HER2-low breast cancer
This trial uses a special PET scan to see if your breast cancer has low levels of a protein called HER2. This could help doctors choose the right treatment for you.
Sherbrooke, QuebecAges 18 years+ - NCT06727227Recruiting
Study of Enhertu for HER2-low breast cancer
This study looks at how well the drug Enhertu works for patients with HER2-low breast cancer that has spread. If you are already planning to start Enhertu, researchers will collect data from your regular care to learn more about its effectiveness.
Panagyurishte, PazardzhikAges 18 years+ - NCT06706557Recruiting
Studying tumor DNA in HER2-low advanced breast cancer
This trial looks at tumor DNA in the blood of people with a certain type of advanced breast cancer called HER2-low. The goal is to learn more about this cancer and how it changes over time, which may help guide future treatments.
Milan, MIAges 18 years+ - NCT06551116Recruiting
Better HER2 testing for HER2-low breast cancer on Enhertu
This study looks at using a more detailed lab test to measure HER2 levels in people with HER2-low metastatic breast cancer who are starting or have just started treatment with Enhertu. The goal is to see if this test can help doctors better understand who might benefit from Enhertu.
San Francisco, CaliforniaAges 18 years+ - NCT06533826RecruitingPhase 2
Testing two antibody drugs for HER2-low breast cancer
This trial tests two antibody-drug conjugates (Enhertu and Datroway) for breast cancer that is HER2-low or HER2-0. It aims to find the best treatment sequence for people whose cancer has stopped responding to prior therapy.
Birmingham, AlabamaAges 18 years+ - NCT06486883RecruitingPhase 2
T-DXd vs CDK4/6i plus hormone therapy for advanced HR-positive, HER2-low breast cancer
This trial compares two treatments for advanced breast cancer that is HR-positive, HER2-low or ultralow, and a non-luminal subtype. It tests if a targeted antibody-drug conjugate (T-DXd) works better than the usual first-line therapy combining a CDK4/6 inhibitor with hormone therapy. This study is for people who have not had any treatment for advanced disease.

JSKN003 vs. doctor's choice for HER2-low breast cancer
This trial compares a new experimental drug, JSKN003, to standard treatments chosen by your doctor for advanced breast cancer that tests as HER2-low (IHC 1+ or 2+ but not amplified). It's for people whose cancer has spread or can't be removed and who have already had one or two lines of chemotherapy.

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.
Fullerton, CaliforniaAges 18 years+ - NCT05950945RecruitingPhase 3
Trastuzumab deruxtecan for HER2-low metastatic breast cancer
This trial tests a targeted antibody-drug medicine (trastuzumab deruxtecan, T-DXd) in people with metastatic breast cancer that is HER2-low or HER2 IHC 0. It may help by treating tumors that haven’t previously received anti-HER2 treatment in the metastatic setting.
