PURPOSE: + non-small cell lung cancer. METHODS: TRUST-I and TRUST-II were phase II, single-arm, open-label, nonrandomized, multicenter trials. Efficacy outcomes were pooled from TRUST-I and TRUST-II pivotal cohorts. The safety population comprised all patients treated with once-daily oral taletrectinib 600 mg pooled across the taletrectinib clinical program. The primary end point was independent review committee-assessed confirmed objective response rate (cORR). Secondary outcomes included intracranial (IC)-ORR, progression-free survival (PFS), duration of response (DOR), and safety. RESULTS: As of June 7, 2024, the efficacy-evaluable population included 273 patients in TRUST-I and TRUST-II. Among TKI-naïve patients (n = 160), the cORR was 88.8% and the IC-cORR was 76.5%; in TKI-pretreated patients (n = 113), the cORR was 55.8% and the IC-cORR was 65.6%. In TKI-naïve patients, the median DOR and median PFS were 44.2 and 45.6 months, respectively. In TKI-pretreated patients, the median DOR and median PFS were 16.6 and 9.7 months. The cORR in patients with G2032R mutation was 61.5% (8 of 13). Among 352 patients treated with taletrectinib 600 mg once daily, the most frequent treatment-emergent adverse events (TEAEs) were GI events (88%) and elevated AST (72%) and ALT (68%); most were grade 1. Neurologic TEAEs were infrequent (dizziness, 21%; dysgeusia, 15%) and mostly grade 1. TEAEs leading to discontinuations (6.5%) were low. CONCLUSION: Taletrectinib showed a high response rat...
