Recruiting studies
- NCT06120283RecruitingPhase 1
Testing a new drug for breast cancer and other solid tumors
This trial tests a new oral drug (BGB-43395) alone or with other treatments for people with advanced breast cancer or other solid tumors that depend on CDK4. It aims to find safe doses and see if the drug helps shrink tumors or slow growth.
Denver, ColoradoAges 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.

A study of T-DXd and rilvegostomig for HER2-positive bile duct cancer
This trial tests a new combination of two drugs (T-DXd and rilvegostomig) for people with advanced bile duct cancer that has not been treated before. The cancer must have high levels of a protein called HER2. This study compares the new drugs to standard treatments.
Scottsdale, ArizonaAges 18–99 - NCT05256225RecruitingPhase 3
Adding Herceptin medicines to chemo for HER2-positive endometrial cancer
This Phase 3 trial tests whether adding Herceptin Hylecta or Phesgo to standard chemotherapy works better than chemotherapy alone for HER2-positive serous endometrial cancer or carcinosarcoma. It may help by improving how well treatment controls or shrinks the cancer.

Toronto, OntarioAges 18 years+ - NCT06492616RecruitingPhase 3
Elacestrant vs standard hormone therapy for high-risk early breast cancer
This trial tests a new hormone therapy pill (elacestrant) against standard hormone therapy for people with a common type of early breast cancer (ER+, HER2-) that has a higher chance of returning. You may qualify if you've already been on hormone therapy for 2 to 5 years and want to see if a different pill works better.
Daphne, AlabamaAges 18 years+ - NCT07085767RecruitingPhase 3
Palazestrant and ribociclib for first-line advanced breast cancer
This trial tests a new drug (palazestrant) combined with ribociclib for people with a common type of advanced breast cancer that is estrogen receptor-positive and HER2-negative. You may qualify if you haven't had treatment for advanced disease and your cancer has either just been found or came back long after completing hormone therapy.

BL-M07D1 for HER2-positive or HER2-low breast cancer
This Phase 1 study tests BL-M07D1, a new investigational medicine, in people with HER2-positive or HER2-low breast cancer (and other solid tumors) that can’t be operated on or has spread. It aims to find a safe dose and learn how well the treatment may work based on HER2 levels in tumor tissue.
Fuzhou, FujianAges 18–75 - NCT07007559RecruitingPhase 2
Evorpacept with trastuzumab and chemo for HER2-positive breast cancer
This study tests an experimental drug called evorpacept when given with trastuzumab and chemotherapy for people with HER2-positive breast cancer that has spread. The goal is to see if this combination can shrink tumors or slow down the cancer.
Tucson, ArizonaAges 18 years+ - NCT07543536RecruitingPhase 3
Megestrol Acetate for Fatigue in HER2+ Breast Cancer
This study tests whether a medication called megestrol acetate can help reduce severe tiredness and fatigue in people with advanced breast cancer who are receiving a targeted therapy called T-DXd (trastuzumab deruxtecan). Fatigue is a common side effect that can really impact quality of life.
Guangzhou, GuangdongAges 18–75 - NCT05985655RecruitingPhase 1/Phase 2
Study of GTAEXS617 for advanced solid tumors
This trial tests a new drug called GTAEXS617 for adults with certain advanced solid tumors that have not responded to standard treatments. It aims to see if the drug is safe and effective.
Los Angeles, CaliforniaAges 18 years+ - NCT07195695RecruitingPhase 3
Zongertinib after surgery for HER2-mutated lung cancer
This trial tests a new pill, zongertinib, against standard of care for people with early-stage (II–IIIB) non-small cell lung cancer that has a specific HER2 mutation in the tyrosine kinase domain. The goal is to see if zongertinib can prevent the cancer from coming back after complete surgical removal.
Fresno, CaliforniaAges 18 years+ - NCT05304962RecruitingPhase 1
Test drug RGT-419B for advanced ER+ HER2- breast cancer
This Phase 1 study tests a new drug (RGT-419B), given alone or with hormone (endocrine) therapy, in people with advanced ER-positive, HER2-negative breast cancer that has progressed after standard treatments. It looks mainly at safety and early signs of how well the treatment may work.
La Jolla, CaliforniaAges 18 years+ - NCT06989112RecruitingPhase 3
First-line treatment for advanced or recurrent endometrial cancer
This trial tests a new combination of drugs for endometrial cancer that has spread or come back. It aims to see if these drugs can shrink tumors and help people live longer. It is for tumors that have a certain protein (HER2) and are mismatch repair proficient (meaning they have a normal DNA repair system).
Tucson, ArizonaAges 18 years+ - NCT05327608RecruitingPhase 2
Time-restricted eating during breast cancer chemotherapy
This study is testing whether time-restricted eating (confining all meals to a specific window each day) can improve the response to chemotherapy in women with newly diagnosed breast cancer. Participants will follow this eating pattern for 16 weeks while receiving their standard chemotherapy, and the researchers will monitor how the tumor shrinks.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07347600Recruiting
Studying inavolisib for a type of advanced breast cancer
This study tests a targeted therapy called inavolisib for people whose breast cancer has spread (advanced or metastatic), is hormone receptor-positive and HER2-negative, has a PIK3CA mutation, and has stopped responding to hormone therapy. It aims to see if inavolisib is safe and works well for them.

Common questions
- Are there clinical trials for her2?
- Yes. Clin2 currently lists 606 recruiting her2 studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a her2 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 her2 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.
