Abstract

Aberrant NTRK gene fusions leading to constitutively activated NTRK proteins are a key driver for a range of adult and pediatric tumors. Small molecule NTRK inhibitors targeting the NTRK ATP site have shown success in the clinic resulting in two approved drugs. Unfortunately, resistance mutations have created the need for additional therapies. In this study, we detail the design, synthesis, and evaluation of novel NTRK BiDAC™ degraders containing a macrocyclic, mutant active, NTRK targeting ligand.
