FDA OKs Taletrectinib for ROS1-Positive Non-Small Cell Lung Cancer
The Food and Drug Governance has given the green light to taletrectinib (Ibtrozi, Nuvation Bio Inc.) as a ROS1 tyrosine kinase inhibitor for patients battling locally advanced or metastatic ROS1-positive non-small cell lung cancer (NSCLC).
The approval for this ROS1 tyrosine kinase inhibitor stems from the TRUST-I and TRUST-II clinical trials. These open-label studies assessed the drug’s effectiveness in 157 patients who had not previously undergone ROS1 TKI treatment and 113 patients who had.
The trials revealed that treatment-naive patients achieved an overall response rate (ORR) of 90% in TRUST-I and 85% in TRUST-II. For those previously treated, the ORR was 52% in TRUST-I and 62% in TRUST-II.
Among those who responded to the treatment,the duration of response (DOR) lasted 12 months or longer in 72% of treatment-naive patients in TRUST-I and 63% in TRUST-II. In the previously treated group, the DOR lasted at least 6 months in 74% of responders from TRUST-I and 83% from TRUST-II.
the FDA advises a daily oral dose of 600 mg of taletrectinib, ensuring no food consumption two hours before or after administration.
Warnings associated with taletrectinib include potential risks of hepatotoxicity, interstitial lung disease/pneumonitis, QTc interval prolongation, hyperuricemia, myalgia with creatine phosphokinase elevation, skeletal fractures, and embryo-fetal toxicity.
