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 - NCT05334069Recruiting
Blood test study for early cancer detection in patients
This study collects blood from people with cancer and people without cancer (or with possible cancer) to test whether new blood tests can detect cancer earlier. Your blood samples help researchers evaluate how well these tests work.
Seattle, WashingtonAges 40–75 - NCT06841354RecruitingPhase 3
Sac-TMT alone or with pembrolizumab for advanced triple-negative breast cancer
This trial tests a new drug, Sac-TMT, given alone or with an immunotherapy drug (pembrolizumab) for people with advanced triple-negative breast cancer who have not yet received any treatment for advanced disease. The goal is to see if this combination can shrink tumors or slow the cancer's growth.
Seattle, WashingtonAges 18 years+ - NCT03670966RecruitingPhase 1/Phase 2
Targeted iodine therapy, then donor transplant for hard leukemias
This trial tests an antibody-linked radioactive iodine treatment, followed by a donor stem cell transplant, for people with relapsed or refractory high-risk acute leukemia or certain MDS. It may help patients by targeting leukemia cells and then using a new immune system to control the disease.
Seattle, WashingtonAges 18–75 - NCT06513962RecruitingPhase 3
Triptorelin to protect ovaries in young women with cancer
This study tests whether a medicine called triptorelin can protect the ovaries in young women and teens receiving strong chemotherapy for cancer. If you are newly diagnosed with a cancer (other than breast cancer) and are about to get certain chemotherapy drugs, this trial may help preserve your fertility.
Seattle, WashingtonAges Up to 39 years - NCT05422911RecruitingPhase 2
Abiraterone, enzalutamide, or apalutamide for early castration prostate cancer
This Phase 2 trial tests whether abiraterone, enzalutamide, or apalutamide can work better (or differently) in men with prostate cancer that is considered “castration-sensitive.” It compares these hormone-blocking treatments to find an approach that controls the cancer more effectively and safely.
Seattle, WashingtonAges 18 years+ - NCT05430971Recruiting
BPDCN international registry for patients to be followed over time
This trial is a patient registry for people with blastic plasmacytoid dendritic cell neoplasm (BPDCN). It helps researchers learn more about the disease by collecting information from patients as they get care.
Seattle, WashingtonAges Any age - 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+ - NCT07052630Recruiting
Planning advance care after stem cell transplant
This study tests a program that helps stem cell transplant survivors plan their future care with their doctors. It uses a website and a patient navigator to guide you through conversations about your goals and values.
Seattle, WashingtonAges 18 years+ - NCT05999994RecruitingPhase 2
Testing new drugs for children and young adults with cancer
This trial tests several experimental drugs for children and young adults with cancer. It aims to find safe and effective treatments by matching participants to one of several drug studies based on their cancer type and health.
Seattle, WashingtonAges 1–39 - NCT05544019RecruitingPhase 1
Testing an investigational drug for mature B-cell cancers
This early (Phase 1) study tests SGR-1505, an experimental treatment, in people with certain mature B-cell cancers. It’s mainly designed to see how the drug works in the body and to check safety, and it may offer an option if standard treatments aren’t enough.
Seattle, WashingtonAges 18 years+ - NCT05687110RecruitingPhase 1
Testing novobiocin for tumors with DNA repair gene changes
This Phase 1 study tests whether novobiocin is safe and finds the best dose for people whose tumors have specific DNA repair gene mutations. It may help if your cancer is hard to treat with standard options, including certain patients who already tried PARP inhibitors.
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+ - NCT05554406RecruitingPhase 2
New drug therapy for high-risk AML
This trial is testing new drug combinations for people with newly diagnosed, high-risk AML who have not yet started treatment. It aims to find more effective therapies for this aggressive form of leukemia.

Studying a new drug for cancers with a specific TP53 change
This trial tests a new drug (rezatapopt) for people with advanced cancers that have a specific change in the TP53 gene, called Y220C. The drug is designed to target this change and may slow or stop cancer growth. Some participants may also receive an immunotherapy drug called pembrolizumab (Keytruda).

MyeloMATCH screening to match you to AML or MDS treatment
This study screens people with newly suspected acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) to see which treatment approach fits best—either a specific study treatment or standard care. It may help by directing you to the right option and by sharing your blood/bone marrow samples for research.

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.
