Recruiting studies in Washington
- 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.
Seattle, WashingtonAges 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.
Seattle, WashingtonAges 18 years+ - NCT06435429RecruitingPhase 3
Zanidatamab vs trastuzumab for HER2+ breast cancer
This study compares a new drug called zanidatamab against trastuzumab (Herceptin), both given with a chemotherapy of your doctor's choice. It is for people with HER2-positive breast cancer that has spread and who have already tried T-DXd treatment.
Seattle, WashingtonAges 18 years+ - NCT07102381RecruitingPhase 2
Zanidatamab plus chemo before surgery for HER2+ breast cancer
This trial tests a new drug called zanidatamab combined with chemotherapy to shrink HER2-positive breast cancer before surgery. It may help improve treatment outcomes for people with stage 2 or 3 breast cancer that has not spread.
Puyallup, WashingtonAges 18 years+ - NCT04585750RecruitingPhase 1/Phase 2
Study drug for TP53 Y220C-mutated advanced cancers
This early-phase study tests PC14586 (rezatapopt) in people with advanced or metastatic solid cancers that carry a specific TP53 mutation called Y220C. It mainly looks at safety and how well the treatment may work, sometimes combined with pembrolizumab.
Seattle, WashingtonAges 12 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.
Kennewick, WashingtonAges 18 years+ - NCT06253871RecruitingPhase 1
Study of IAM1363 for HER2 Cancers
This trial tests a new oral drug called IAM1363 for people with HER2-altered cancers that have stopped responding to previous treatments. The goal is to see if the drug is safe and how well it works against these cancers.
Seattle, WashingtonAges 18 years+ - NCT06625775RecruitingPhase 1
Study of BBO-10203 for advanced solid tumors
This trial tests a new drug called BBO-10203, alone or combined with other cancer treatments, for people with certain advanced breast, colorectal, or lung cancers. It aims to see if the drug is safe and effective.
Seattle, WashingtonAges 18 years+ - 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).
Seattle, WashingtonAges 18 years+ - NCT05150691RecruitingPhase 1/Phase 2
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.
Seattle, WashingtonAges 18 years+ - 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.
Edmonds, WashingtonAges 18 years+ - 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.

What taking part in a her2-positive breast cancer study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
