New Recruiting Trial: Entrectinib as a Single Agent in Upfront Therapy for Children <3 Years of Age With NTRK1/2/3 or ROS1-FUSED CNS Tumors

WHY IT MATTERS

This trial offers a targeted treatment option specifically designed for infants and toddlers with NTRK- or ROS1-fused CNS tumors, a group that has historically had very limited treatment options and poor outcomes.

Researchers at St. Jude Children's Research Hospital are testing a drug called entrectinib to treat very young children (under 3 years old) who have brain or spinal cord tumors caused by changes in specific genes called NTRK1, NTRK2, NTRK3, or ROS1. This is a Phase 2 trial, meaning they've already tested the drug in a small group and now want to see if it works well in more patients. The trial is now accepting new patients and is expected to start in April 2026.
