Study of Oral Lucitanib (E-3810), a Dual VEGFR-FGFR Tyrosine Kinase Inhibitor, in Patients With Solid Tumors

Co-selective inhibition of VEGFRs and FGFR has the potential benefit of blocking the two most relevant players in tumor angiogenesis and simultaneously targeting proliferation in FGF-driven tumors. Lucitanib is a novel dual-targeted small molecule inhibitor of VEGFR1, 2, 3 and FGFR1 showing strong anti-angiogenic and anti-tumor activity in preclinical models at well-tolerated oral doses, with a favorable pharmacokinetic profile. These properties make it an attractive candidate for development in humans. This is an open-label, uncontrolled, non-randomized, PhaseI/IIa study and its primary objective is to determine the Maximum Tolerated Dose (MTD) of Lucitanib administered orally, once daily, on a continuous schedule over the initial 28-day cycle. Secondary objectives are to determine the safety profile, pharmacokinetics, pharmacodynamics and antitumour activity of Lucitanib, given as a single agent to adult patients with advanced solid tumours. The study consists of two phases, a dose escalation phase followed by a dose-expansion phase at the identified Recommended Dose (RD). Eligible patients have histologically or cytologically confirmed locally advanced or metastatic solid tumours, relapsed or refractory to standard therapy. For the dose expansion, patients should have tumours bearing FGFR1 or 11q 12-14 amplification, assessed by FISH or CGH array, or "sensitive" to antiangiogenic treatment. These latter are defined as patients who have relapsed after having experienced stable disease (lasting at least six months) or partial response with prior treatment with an approved antiangiogenic regimen or patients with tumour types known to be potentially responsive to antiangiogenic agents but without such pretreatment if no antiangiogenic agents were approved and/or available for that specific condition (e.g thyroid cancer, thymic carcinoma). Serial safety assessments, including evaluation of symptoms, physical examination and blood and urine laboratory analyses are
