Taletrectinib (Ibtrozi): A Comprehensive Oncological Drug Monograph

Executive Summary

Taletrectinib, marketed as Ibtrozi, is a next-generation, orally administered, central nervous system (CNS)-active, selective tyrosine kinase inhibitor (TKI) that has emerged as a significant therapeutic advancement for ROS1-positive (ROS1+) non-small cell lung cancer (NSCLC).[1] On June 11, 2025, the U.S. Food and Drug Administration (FDA) granted approval for taletrectinib for the treatment of adult patients with locally advanced or metastatic

ROS1+ NSCLC, a decision that applies to both TKI-naïve and previously treated patient populations.[4] This approval is predicated on a robust body of evidence from the pivotal Phase 2 clinical trials, TRUST-I and TRUST-II, which demonstrated high and durable systemic and intracranial response rates.[2]

The clinical profile of taletrectinib is distinguished by several key attributes that address critical unmet needs in the management of ROS1+ NSCLC. The agent exhibits potent activity against the common crizotinib-acquired resistance mutation, ROS1 G2032R, a significant mechanism of treatment failure for first-generation TKIs.[3] Furthermore, taletrectinib was designed for superior penetration of the blood-brain barrier, translating to compelling intracranial efficacy in patients with CNS metastases, a frequent and challenging complication of this disease.[3] This is coupled with a favorable neurological safety profile, which is attributed to its high selectivity for ROS1 over tropomyosin receptor kinase B (TRKB), thereby minimizing the dose-limiting neurological adverse events associated with less selective inhibitors.[1]
