The study on the efficacy and safety of vandetanib in previously treated RET-rearranged advanced NSCLC patients showed a prolonged PFS and OS, with hypertension, diarrhea, and rash acneiform being the most common adverse events.
Objectives: The LURET phase II study evaluated the efficacy and safety of the multikinase inhibitor vandetanib in patients with previously treatedRET-rearranged advanced non-small cell lung cancer (NSCLC). Among the eligible patients included in the primary analysis, the objective response rate met the primary endpoint (53 %, 90 % confidence interval [CI]: 31-74). Here, we report final survival outcomes of the LURET study. Materials and methods: Nineteen patients with previously treated RET-rearranged advanced NSCLC continuously received 300 mg of oral vandetanib daily. This final analysis provides updated data on progression-free survival (PFS), overall survival (OS) and safety. This study was registered with UMIN-CTR (number UMIN 000010095). Results: Among the 19 patients in the intention-to-treat population, 42 % had been heavily treated with 3 or more prior chemotherapy regimens. The median PFS was 6.5 months (95 % CI, 3.9-9.3) as determined by an independent radiology review committee. The median OS was 13.5 months (95 % CI, 9.8-28.1) and the overall survival rate at 12 months was 52.6 % (95 % CI 28.7-71.9). The most common adverse events were hypertension (84.2 %), diarrhea (78.9 %), and rash acneiform (63.2 %). Overall, 11 patients (57.9 %) had adverse events leading to a dose reduction, although the safety profile was consistent with that reported in previous studies. Conclusion: Our results indicated that vandetanib enabled a prolonged and clinically meaningful PFS and OS in patients with previously treatedRET-rearranged advanced NSCLC at the updated final analysis. The safety profile was consistent with that reported in previous studies, although most of the patients experienced off-target adverse events besides RET.
