Recruiting studies near Seattle
- NCT06859424RecruitingPhase 2
Testing a new GVHD prevention method after donor stem cell transplant

Seattle, WashingtonAges 18–66 - NCT07091617Recruiting
Better genetic testing for young adults with cancer
This study tests a new way to offer genetic testing to young adults (ages 18-39) who have or had cancer. The goal is to make it easier for you to learn if you have inherited gene changes that could affect your cancer and your family's health.
Seattle, WashingtonAges 18 years+ - NCT06051695RecruitingPhase 1/Phase 2
CAR T cell therapy for mesothelin-positive solid tumors
This trial tests a new type of immune cell therapy (CAR T-cells) designed to target cancer cells that have a protein called mesothelin but have lost a marker that lets them hide from the immune system. It's for people with advanced solid tumors who have already tried standard treatments.
Seattle, WashingtonAges 18 years+ - NCT04829136Recruiting

Seattle, WashingtonAges 18 years+ - NCT06518057RecruitingPhase 2
Sparing memory during brain radiation for leptomeningeal metastases
This trial tests a special type of radiation that avoids the memory center of the brain (the hippocampus) while treating cancer that has spread to the lining of the brain and spinal cord. It may help reduce side effects on thinking and memory for people with breast or lung cancer.
Seattle, WashingtonAges 18 years+ - NCT06817889RecruitingPhase 2
Remdesivir for RSV in people with weak immune systems
This trial tests if remdesivir can safely treat RSV (a respiratory virus) in people with weakened immune systems, such as those who have had a stem cell or bone marrow transplant, CAR T-cell therapy, or are being treated for blood cancer. If you have a confirmed RSV infection in your nose or throat and are at moderate or high risk for complications, you may be able to join.
Seattle, WashingtonAges 18 years+ - NCT06126276RecruitingPhase 2
Testing neratinib with or without palbociclib for HER2+ solid tumors
This trial tests two targeted drugs—neratinib alone or with palbociclib—for people with HER2-positive solid tumors (other than breast cancer) that have returned or not gone away. The goal is to see if blocking HER2 and CDK4/6 can shrink or slow the tumor.
Seattle, WashingtonAges 18 years+ - NCT04256317RecruitingPhase 2/Phase 3
Azacitidine pills with or without venetoclax for certain blood cancers
This study tests whether a pill form of azacitidine (ASTX030) helps people with myelodysplastic syndromes (MDS), CMML, or AML. Some groups may also receive venetoclax; the goal is better blood cancer control for people who aren’t good candidates for intensive chemotherapy.
Seattle, WashingtonAges 18 years+ - NCT07213804RecruitingPhase 3
Study of sofetabart mipitecan for ovarian cancer
This trial tests a new drug called sofetabart mipitecan for people with ovarian cancer that has come back after treatment. It is for those whose cancer is either resistant to platinum chemo (Part A) or sensitive to it (Parts B and C). The study will see if the drug can help shrink or slow the cancer.
Seattle, WashingtonAges 18 years+ - NCT03866382RecruitingPhase 2
Immunotherapy plus a targeted drug for rare genitourinary tumors
This Phase 2 study tests whether nivolumab and ipilimumab (immunotherapy drugs) plus cabozantinib (a targeted anti-cancer drug) can shrink or control rare cancers of the urinary/reproductive system that have spread. It may help by boosting the immune system and blocking cancer growth signals at the same time.
Seattle, WashingtonAges 18 years+ - NCT05918263Recruiting
Exercise to slow prostate cancer in men on active surveillance
This trial tests whether moderate exercise can help keep low-risk prostate cancer from growing in men who are monitoring their cancer instead of treating it right away. It may be especially helpful for men with certain risk factors like obesity or being Black or African American.
Seattle, WashingtonAges 18 years+ - NCT06620302RecruitingPhase 1/Phase 2
Adding DT2216 to chemo for relapsed solid tumors and FLC
This trial is testing whether adding a new drug, DT2216, to standard chemotherapy can help treat solid tumors (not starting in the brain) or fibrolamellar carcinoma (FLC) that have come back or not responded to treatment. It's for children, teens, and young adults (ages 1 to 39).
Seattle, WashingtonAges 1–39 - NCT06966453RecruitingPhase 1/Phase 2
Study of disitamab vedotin for HER2-positive advanced breast cancer

Tegavivint for kids and young adults with hard-to-treat solid tumors
This early-phase study tests tegavivint to see how well it works and how safe it is for children and young adults with solid cancers that have come back or are not responding. It may be an option if your tumor type (including certain lymphomas or desmoid tumors) matches the study’s rules.
Seattle, WashingtonAges 1–30 - NCT06410209RecruitingPhase 2
Walking Juntos: Smartphone program to help Hispanic cancer survivors be active
This study will test if a smartphone program and social media group can help Hispanic/Latino teens and young adults who had childhood cancer become more physically active. You would wear a Fitbit and use a phone app with culturally tailored tips and support.
Seattle, WashingtonAges 15–20 - NCT04871542Recruiting
Predicting risk of immune therapy side effects
This study tries to predict who is more likely to get serious side effects from immune checkpoint medicines used for solid tumors. You may help researchers by answering questionnaires before treatment and during follow-up, and by possibly storing sample specimens.
Seattle, WashingtonAges 18 years+ - NCT00900198Recruiting
Give cancer tissue samples to help future cancer research
This study collects tissue or other cancer-related samples to help researchers better understand cancer and develop better tests or treatments. You can join if you are being evaluated for or treated for cancer, and you agree to let your samples be used for research.
Seattle, WashingtonAges 2 months+ - NCT06095089RecruitingPhase 1
Study of two drugs for advanced prostate cancer
This trial tests a new combination of two study drugs for people with advanced prostate cancer that has spread or is no longer responding to hormone therapy. The goal is to see if the combination is safe and works against the cancer.
Seattle, WashingtonAges 18 years+ - NCT07141407Recruiting
Phone coaching to help plan cancer care
This study tests whether telephone coaching sessions can help people with advanced cancer and their caregivers talk about and plan for future medical care. You and a support person would join coaching calls together.

What taking part in a neoplasms 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.
