The FDA approved taletrectinib for ROS1-positive non-small cell lung cancer on June 11, offering a new treatment option. This kinase inhibitor, based on data from TRUST-I and TRUST-II trials, shows impressive efficacy, especially in TKI-naïve patients, demonstrating response rates up to 90%.The drug presents a potentially favorable toxicity profile compared to existing therapies. Clinical trials highlight taletrectinib’s role in both first-line and resistant settings, offering a promising outlook for patients battling this NSCLC subtype. This approval expands treatment options, potentially making taletrectinib a first-line standard, especially in the U.S., alongside entrectinib and repotrectinib.

FDA Approves Taletrectinib for ROS1-Positive Non-Small Cell Lung Cancer
The Food and Drug Administration (FDA) approved taletrectinib (Ibtrozi; Nuvation Bio Inc.) on June 11 for treating ROS1-positive locally advanced or metastatic non-small cell lung cancer (NSCLC). The approval is based on results from the TRUST-I and TRUST-II trials.
These multinational studies evaluated the drug’s efficacy in both tyrosine kinase inhibitor (TKI)-naïve and TKI-pretreated patients, assessing its role in first-line and resistant settings for non-small cell lung cancer treatment. The trials, TRUST-I (NCT04395677) and TRUST-II (NCT04919811), were single-arm studies.
Taletrectinib demonstrated a 90% response rate in TKI-naïve patients in the TRUST-I trial and 85% in TRUST-II. These results represent a significant improvement compared to existing therapies like crizotinib (Xalkori; Pfizer) and entrectinib (Rozlytrek; Genentech). Durations of response at 12 months or more were 72% and 63%, respectively.
While cross-trial comparisons shoudl be made cautiously, these high response rates suggest taletrectinib could become a first-line standard for this NSCLC subtype and its rare ROS1 mutation. The drug also presents a favorable toxicity profile,with a lower risk of central nervous system (CNS) toxicity compared to other treatments,though it has a slightly higher rate of gastrointestinal (GI) effects. Clinicians may find this balance preferable,as managing GI toxicity can be easier than CNS adverse effects.
Access to taletrectinib may vary globally, with crizotinib remaining the only option in some regions. Though, in the U.S., taletrectinib is expected to join entrectinib and repotrectinib as a leading TKI for ROS1-positive NSCLC, offering personalized treatment based on individual toxicity tolerance. The approval signifies progress in targeting ROS1 resistance and improving outcomes for lung cancer patients.
What’s next
Taletrectinib is poised to become a key option in the personalized treatment of ROS1-positive non-small cell lung cancer, particularly in the U.S., pending its availability and integration into treatment guidelines.
