Recruiting studies near Seattle
- NCT05783323RecruitingPhase 2
Larotrectinib plus radiation for thyroid cancer with NTRK fusion
This Phase 2 trial tests larotrectinib (a targeted medicine) to help radioactive iodine (RAI) work better in people with differentiated thyroid cancer that has an NTRK gene fusion. It may improve how much thyroid cancer the RAI can reach and shrink.
Seattle, WashingtonAges 2–99 - NCT06458036RecruitingPhase 2
Selpercatinib before radioactive iodine for RET-positive thyroid cancer
This study tests whether a targeted drug called selpercatinib, taken before radioactive iodine therapy, can help treat thyroid cancer in children and young adults who have a specific genetic change (RET fusion or mutation). The drug may make the cancer more sensitive to the radioactive iodine treatment that follows.
Seattle, WashingtonAges 2–25 - NCT06475989RecruitingPhase 3
Targeted Drug Combo vs. Chemo for Advanced Thyroid Cancer
This study tests a new combination of targeted drugs (dabrafenib and trametinib) compared to chemotherapy (cabozantinib) for people with a specific type of advanced thyroid cancer called BRAF-mutated differentiated thyroid cancer. The goal is to see which treatment works better.

Test targeted drugs to help radioactive iodine reach thyroid cancer
This study looks at whether certain cancer “targeted therapy” medicines can make radioactive iodine (RAI) therapy work better for thyroid cancer that has spread to the lungs. It also involves taking special whole-body scans to measure how much radioactive iodine gets taken up by the cancer.

Radiation and immunotherapy combo for DLL3-positive cancers
This trial combines radiation with an immunotherapy drug called tarlatamab to treat cancers that make a protein called DLL3. The goal is to see if this combination works better than either treatment alone for people with certain types of lung cancer and other tumors that have not responded to prior therapy.

Study medicine for BRAF-mutated advanced solid tumors
This Phase 1 trial studies how PF-07799544 works and what dose is safest in people with advanced cancer that has a specific genetic change called BRAF V600. You may receive it alone or with another treatment, depending on the tumor group, to see if it can treat the cancer.

What taking part in a differentiated thyroid 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.
