AI matches your cancer tests to possible treatment trials
This trial uses an AI system to help match people with certain cancer types and specific tumor test results (like gene or protein markers) to relevant clinical trials. It may help you and your doctor find studies that fit your cancer biology faster.
Seattle, WashingtonAges Any age - NCT06013423RecruitingPhase 2
Cord blood transplant with chemo and radiation for high-risk blood cancers
This trial tests a cord blood transplant after a reduced-intensity chemotherapy and radiation regimen for patients with high-risk blood cancers like leukemia, lymphoma, or MDS. The goal is to see if this approach can help destroy cancer cells and restore healthy blood cells.
Seattle, WashingtonAges 6 months–65 years - NCT00756665Recruiting
Study of careful monitoring for prostate cancer
This study follows people with early-stage prostate cancer who choose active surveillance instead of immediate treatment. It aims to see how monitoring with repeat prostate biopsies and follow-up works over time.
Seattle, WashingtonAges 21 years+ - NCT04981119Recruiting
Test apheresis for CAR T manufacturing in HLA-A2 solid tumors
This trial studies how a process called apheresis is used to make CAR T cells for people with certain solid tumors. It is designed for tumors that have lost a specific immune marker (HLA-A*02), which may affect how well CAR T therapies work.
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+ - 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+ - NCT01255748Recruiting
Registry study tracking outcomes after radiation treatment
This registry study collects information from people who are planning to receive radiation therapy. The goal is to better understand treatment outcomes and help improve radiation care over time.

Dexrazoxane study to monitor heart damage in cancer survivors
This study tests dexrazoxane (DRZ) to see how it affects blood and heart-related “biomarkers,” or measurable signs of heart damage, after cancer treatment. It mainly targets survivors who may be at risk for cardiomyopathy (heart muscle weakness) or related heart failure.

Caring registry study for children and young people with cancer
This study keeps a careful record of children, teens, and young adults with cancer (and some related growths) and may follow them over time. It helps researchers better track outcomes and future contact so care can improve.
Seattle, WashingtonAges Up to 25 years - NCT02474160Recruiting
Banking cancer tissue and blood for future research
This study collects and stores leftover or newly taken samples of tissue and blood from people with cancer. The goal is to build a research library that can help investigators study cancer and develop better tests or treatments.

Comparing two red blood cell transfusion thresholds for people with high-grade myeloid neoplasms, AML or B-ALL
This study compares two different strategies for when to give red blood cell transfusions to people receiving intensive chemotherapy or stem cell transplant for high-grade myeloid neoplasms, AML or B-ALL. The goal is to see which approach better improves quality of life and daily function.

Test drug tulmimetostat for advanced cancers and lymphomas
This early-phase study tests tulmimetostat (DZR123) to shrink or control advanced solid tumors and certain lymphomas, and it may also test a combination in some prostate cancer groups. If you qualify, you’ll receive the study drug and be monitored closely, including blood tests and a request for tumor tissue to look for biomarkers.

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.
