Recruiting studies
- NCT01042379RecruitingPhase 2
Adaptive drug trial for newly diagnosed breast cancer
This study tests personalized, changing treatment plans (given before surgery) to find better options for your specific breast tumor. You may be asked for extra breast-tissue testing to help match you with the most suitable study drug(s).
Birmingham, AlabamaAges 18 years+ - NCT07140393RecruitingPhase 1/Phase 2
Combination therapy for advanced solid tumors
This study tests a new drug called HRS-4508 combined with other cancer treatments for people with advanced solid tumors that cannot be removed by surgery or have spread. The goal is to see if the combination is safe and effective.
Beijing, Beijing MunicipalityAges 18–75 - NCT05408845RecruitingPhase 2
Study drug vs standard care for HER2 salivary gland cancer
This Phase 2 trial tests how well ado-trastuzumab emtansine (and compares to two standard treatment options) works for salivary gland cancers that are HER2-positive or HER2-low. It aims to see whether the study drug can control cancer better and with acceptable side effects.
Birmingham, AlabamaAges 18 years+ - NCT05760612RecruitingPhase 3
After breast cancer surgery, test neratinib plus trastuzumab
This trial studies whether adding neratinib to standard trastuzumab treatment after neoadjuvant (before-surgery) therapy lowers the risk of breast cancer coming back. It is for people whose breast cancer is hormone-receptor positive and HER2 positive, with residual cancer found after neoadjuvant treatment.
GuangzhouAges 18–70 - NCT06928818Recruiting
T-DM1 after T-DXd for advanced HER2-positive breast cancer
This trial looks at whether a different targeted therapy, T-DM1, can work for women with advanced HER2-positive breast cancer after they have already tried another targeted therapy called T-DXd (Enhertu). If you have progressed while on T-DXd and have not had more than three previous treatments for advanced cancer, you may be able to join.
SeoulAges 19 years+ - NCT05376878RecruitingPhase 4
PET/MRI scan to guide treatment in HER2+ brain metastatic breast cancer
This trial tests a special PET/MRI imaging scan using a labeled drug to help doctors evaluate HER2+ breast cancer that has spread to the brain. It focuses on patients who plan to receive fam-trastuzumab deruxtecan, a targeted cancer medicine, and aims to see how well the scan can support treatment decisions.
Duarte, CaliforniaAges 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.
Cerritos, CaliforniaAges 18 years+ - NCT06217185RecruitingPhase 4
Pyrotinib and trastuzumab with chemo for HER2+ advanced breast cancer

Baden-Baden, Baden-WurttembergAges 18 years+ - NCT07497386RecruitingPhase 2
Trastuzumab rezetecan for advanced breast cancer
This trial tests a new drug, trastuzumab rezetecan, for women with breast cancer that has come back or spread and cannot be removed by surgery. It's for those who haven't had chemotherapy for advanced disease but have tried hormone therapy and it stopped working.
Beijing, Beijing MunicipalityAges 18–75 - NCT07358182Recruiting
Trastuzumab-rezetecan for breast cancer with HER2 protein
This trial tests a new drug, Trastuzumab-rezetecan, in people with breast cancer that has a certain amount of a protein called HER2. It aims to see if the drug works and is safe for patients who are able to receive it before or after surgery, or for those whose cancer has spread and has been treated before.
Guangzhou, GuangdongAges 18 years+ - NCT07340398RecruitingPhase 2
Testing new drug combos for HER2-positive breast cancer not responding to first therapy
This trial tests a new combination of drugs for people with HER2-positive early breast cancer whose tumors did not respond well to the first round of standard targeted therapy plus chemo. The goal is to see if switching to trastuzumab-rezetecan plus pertuzumab or a different chemo combo (nab-paclitaxel, carboplatin, trastuzumab, and pyrotinib) can shrink the tumor before surgery.
HangzhouAges 18–75 - NCT05159193RecruitingPhase 3
Pre-surgery chemotherapy and antibodies for HER2 breast cancer
This phase 3 trial compares two pre-surgery treatment plans for people with HER2-positive invasive breast cancer that has spread to nearby lymph nodes. It aims to see which plan works better to shrink the tumor before surgery and improve outcomes.
Guandong, GuangdongAges 18–70 - NCT05292742RecruitingPhase 2
Continue targeted breast cancer therapy or switch to a new combo
This Phase 2 study compares two treatment plans after breast surgery when cancer did not fully disappear before surgery. It tests whether adding trastuzumab, pyrotinib, and capecitabine works better than continuing the original targeted therapy.

Common questions
- Are there clinical trials studying Trastuzumab?
- Yes. Clin2 currently lists 235 recruiting studies that include Trastuzumab, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Trastuzumab trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Trastuzumab an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Trastuzumab or a specific trial is right for you.
