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 performed throughout the study. Cardiac functions and blood pressure are monitored in consultation with a cardiologist. PK parameters are determined on plasma samples collected during the first 4-week cycle and analyzed using a validated LC-MS/MS method. Correlative studies include: (i) quantitative assessment of the effects of E-3810 on tumor vasculature by DCE-MRI and DCE-US imaging; (ii) assay of angiogenesis biomarkers i.e. soluble VEGFR2, VEGFR1, VEGF, bFGF, Collagen IV, FGF23 and PIGF(by ELISA) and circulating endothelial and progenitors cells (CEC and CEP). Tumor response is based on imaging according to RECIST; circulating tumor cells (CTC) are measured by the immunomagnetic CellSearch method.

In patients with tumours bearing FGFR1 amplifications the efficacy of Lucitanib will be formally tested according to a phase IIa design (one-stage Flaming design, H0=0.05, H1=0,30, power 0,80.

Exclusion Criteria:

1. Active central nervous system (CNS) metastases not controlled by prior surgery or radiotherapy and/or low dose steroids

2. Haematologic malignancies (including leukaemia of any form, lymphoma, and multiple myeloma)

4. Treatment with any anticancer agent within 3 weeks, including investigational agents, chemotherapy, immunotherapy, biologic or hormonal therapy, surgery or radiation therapy (6 weeks for nitrosoureas, mitomycin or bevacizumab); luteinizing hormone releasing hormone (LHRH) agonist for prostate and mitotane for adrenal carcinoma are allowed.
