Abstract

Background: Lucitanib is a novel multi-target inhibitor of FGFR1-3, VEGFR 1-3, and PDGFR α/β. Here, we evaluated the safety, tolerability, and preliminary efficacy of lucitanib in recurrent and metastatic nasopharyngeal carcinoma (RM-NPC). Methods: Patients with pretreated RM-NPC were randomly divided into two treatment arms: continuous or intermittent treatment. The primary endpoint was safety and tolerability. Secondary endpoints were objective response rate (ORR), disease control rate (DCR), and progression-free survival (PFS). Results: One hundred percent of patients in the continuous arm and 90% of patients in the intermittent arm had at least one treatment-related AE (TRAE). Grade ≥3 related TRAEs occurred in 5 patients in the continuous arm (5/10, 50%). No TRAEs grade >3 occurred in the intermittent arm. The ORR and DCR of the continuous arm was 20% and 90%, and the intermittent arm was 10% and 60%, respectively. All responses were observed by the first evaluation. The duration of response was more than 1 year, with two patients still on treatment with sustained response at more than 3 years. Conclusion: Lucitanib has promising clinical activity and tolerable safety profile in heavily pretreated patients with NPC. Patients who responded to lucitanib treatment generally achieved a long DoR. Lucitanib is now being evaluated in phase II/III studies. ClinicalTrials.gov identifier: NCT03260179
