Recruiting studies near Seattle
- NCT04606446RecruitingPhase 2
Study drug for ER-positive, HER2-negative cancers after treatment
This Phase 2 study tests a new Pfizer medicine (PF-07248144) for certain advanced or metastatic breast, prostate, or lung cancers that have not responded to standard treatment or no standard options exist.

Study drug for advanced solid tumors with tumor tissue testing
This early-stage study tests emiltatug leda-dotin (Emi-Le) in people with advanced or recurring solid cancers. It aims to see how the drug works and how safely it can be given, using tumor tissue testing to help understand who may benefit.
Seattle, WashingtonAges 18 years+ - NCT04969835RecruitingPhase 1
Safety and early response study of AVA6000 for solid tumors
This Phase 1 study tests AVA6000 in people with certain solid tumor cancers, mainly to check safety and how the body processes the drug. It also looks for early signs of tumor response to see if it might help further in later studies.
Seattle, WashingtonAges 18 years+ - NCT04939610RecruitingPhase 1/Phase 2
Studying a targeted radiation drug for advanced solid tumors
This trial tests how safe and effective a targeted radiation medicine (177Lu-FAP-2286) is for people with advanced solid cancers that have limited treatment options. It may help by delivering radiation directly to cancer-related targets and shrinking tumors.
Seattle, WashingtonAges 18 years+ - NCT05118789RecruitingPhase 1/Phase 2
Study drug for ROS1-positive lung or solid tumors
This Phase 1/2 study tests zidesamtinib (NVL-520), a medicine meant to attack cancers that have a ROS1 genetic change. It’s for people with advanced or metastatic ROS1-rearranged NSCLC (lung cancer) and, in one group, other solid tumors.

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+ - NCT05245500RecruitingPhase 1
Study drug for solid tumors with MTAP gene deletion

What taking part in a solid tumor 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.
