Recruiting studies
- NCT06503783RecruitingPhase 1
Study of BL-M17D1 for advanced breast cancer and solid tumors
This trial tests a new drug, BL-M17D1, for people with advanced breast cancer (HER2 positive or negative) or other solid tumors that have spread. It aims to see if the drug is safe and effective.
Harbin, HeilongjiangAges 18–75 - 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.
GrazAges 18 years+ - NCT06481956Enrolling by invitationPhase 2
T-DM1 plus a CDK4/6 inhibitor (ribociclib) for HER2-positive breast cancer

BeijingAges 18 years+ - NCT06135714RecruitingPhase 3
Targeting limited breast cancer spread with focused therapy
This trial tests whether treating just the few spots where breast cancer has spread (called oligometastases) with radiation or surgery can help control the disease. It is for people whose cancer has spread to 3 or fewer places, each small in size, and who are healthy enough for local treatments.
Bunkyō-Ku, TokyoAges 18 years+ - NCT06123988Recruiting
Fasting and exercise for advanced breast cancer
This study looks at whether fasting overnight and/or doing exercise can help improve fatigue and other quality-of-life measures in women with advanced hormone receptor positive breast cancer who are already taking a CDK4/6 inhibitor. Participation may involve following a fasting or exercise plan for a period of time.
Phoenix, ArizonaAges 18 years+ - NCT05800275RecruitingPhase 2
Tucatinib and capecitabine plus spinal trastuzumab for HER2+ cancer
This Phase 2 trial tests a combination of tucatinib and capecitabine (taken by mouth) plus trastuzumab delivered into the spinal fluid, to treat breast cancer that has spread to the leptomeninges (lining around the brain/spinal cord). It may help reduce cancer activity in the spinal fluid and improve symptoms.
BordeauxAges 18 years+ - NCT05878314Recruiting
Testing how hormones and tumor markers guide breast cancer treatment
This study looks at how planned hormone (endocrine) treatment, the menstrual cycle, and lab markers from the tumor may help doctors choose the best treatment for early-stage, hormone-receptor–positive, HER2-negative breast cancer. It may help personalize decisions, including what to do before surgery.
TübingenAges 18 years+ - NCT05894239RecruitingPhase 3
Tested targeted drug for HER2-positive breast cancer with PIK3CA changes
This Phase 3 study tests inavolisib plus Phesgo versus placebo plus Phesgo in people whose breast cancer has both HER2-positive and PIK3CA-mutated tumor markers. The goal is to see if adding inavolisib improves how well the treatment controls the cancer and how safe it is.
Gilbert, ArizonaAges 18 years+ - NCT05872295RecruitingPhase 1
Study drug for HER2-positive advanced cancers
This Phase 1 trial tests IKS014 to see how safe it is and how well it works in advanced solid tumors that have HER2. You may be eligible if your tumor is HER2-positive (including certain “low HER2” types) and your body’s blood counts and organ function are strong enough.
Newport Beach, CaliforniaAges 18 years+ - NCT05769010RecruitingPhase 2
HER2-positive or low breast cancer brain metastasis drug study
This Phase 2 study tests SHR-A1811 in people with HER2-positive (or HER2-low) advanced breast cancer that has spread to the brain. It aims to shrink brain tumors and control the cancer in the brain, especially when there was no need for urgent local treatment like radiation or surgery.
Zhengzhou, HenanAges 18–75 - NCT05582499RecruitingPhase 2
Neoadjuvant treatment study for certain breast cancers
This Phase 2 study tests a “precision platform” approach—treatment before surgery—based on specific test results from your breast tumor. It may help determine whether the treatment plan works better for people with particular breast cancer subtypes and healthy organ function.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05575804RecruitingPhase 1/Phase 2
GQ1001 plus pyrotinib for HER2-positive metastatic breast cancer
This trial tests a combination of two targeted drugs, GQ1001 and pyrotinib, for people with HER2-positive breast cancer that has spread to other parts of the body and has not responded to at least one prior treatment. The goal is to see if this combination can shrink tumors or slow cancer growth.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05523947RecruitingPhase 1/Phase 2
Study drug for HER2-positive solid tumors, with dose changes
This early-stage study tests YH32367, a drug for people whose cancer is HER2-positive. It aims to find a safe dose and see whether it can shrink HER2-positive cancers that have spread or are hard to treat.

Early study of an HER2 drug in advanced solid tumors
This early-phase trial tests DB-1303 and BNT323 together in people with advanced or metastatic solid cancers that have specific HER2 features. It may be an option when standard treatments have stopped working, aiming to find a safer dose and early signs of effectiveness.
Cerritos, CaliforniaAges 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.
Chicago, IllinoisAges 18 years+ - NCT04893109RecruitingPhase 2
Study compares two HER2 breast cancer treatments after surgery
This Phase 2 study tests two different medicines given after breast surgery to reduce the risk of cancer coming back. It is only for people with early-stage HER2-positive breast cancer with limited or no lymph node spread.
