New drug combo targets deadly thyroid cancer in small trial
NCT ID NCT06374602
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This phase 2 trial is testing whether two drugs, pembrolizumab and lenvatinib, can shrink tumors and improve survival in 20 people with anaplastic thyroid cancer, a rare and fast-growing cancer. Participants will receive both drugs and be monitored for response and side effects. The study aims to see if the combination can make inoperable tumors removable by surgery.
