Pilot Study Of Dovitinib In Patients With Vhl Disease.
JOURNAL OF CLINICAL ONCOLOGY(2016)
Abstract
587 Background: Von Hippel-Lindau (VHL) is an autosomal dominant inherited disease occurring in 1 in 35,000 births. Individuals with germline mutations in the VHL gene may phenotypically express a variety of lesions including hemangioblastomas (HBs), pancreatic cysts, renal cysts, and renal cell carcinomas (RCC). Previous studies have shown differentially increased FGFR3 levels in HBs compared to RCC. In this pilot trial, we investigated the safety and efficacy profile of TKI 258 (dovitinib), a tyrosine kinase inhibitor of VEGF and FGF receptors, in VHL related lesions, focusing on HBs. Methods: A MDACC IRB-approved protocol planned to enroll 25 subjects who had genetically confirmed VHL disease or clinical diagnosis of VHL, and measurable HBs with no immediate risk of needing intervention. Dovitinib 500mg/day was given in a 4 week cycle on 5 day on/2 day off schedule. In the absence of adverse events (AE), treatment lasted 6 cycles or until disease progression. Evaluation of response to treatment was don...
