Brief Summary:
Despite the success of anti-angiogenic therapy in multiple treatment settings, a fraction of patients are refractory to vascular endothelial growth factor (VEGF) inhibitor treatment, while the majority of patients will eventually develop evasive resistance. It is proposed that mesenchymal-epithelial transition factor (c-MET) and its ligand hepatocyte growth factor (HGF or scatter factor) contribute to VEGF inhibitor resistance, such that combining a c-MET inhibitor with a VEGF inhibitor will provide additional clinical activity compared to VEGF inhibitor alone. This hypothesis will be tested using the cMET/ALK inhibitor, crizotinib, in combination with the VEGF inhibitor, axitinib.Since this will be the first study of axitinib given in combination with crizotinib, the study will primarily assess the safety and tolerability of the combination regimen.

    Triplicate 12-lead ECG measurements (each recording separated by approximately 2 minutes) were performed and average was calculated. The time corresponding to beginning of depolarization to repolarization of the ventricles (QT interval) was adjusted for RR interval using QT and RR from each ECG by Fridericia's formula (QTcF = QT divided by cube root of RR) and by Bazette's formula (QTcB = QT divided by square root of RR).

    Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Apparent oral clearance was obtained by dividing study drug dose with AUCtau, where AUCtau was area under the plasma concentration-time curve from time zero to the quantifiable concentration at the end of dosing interval.

    Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.

Confirmed responses were those that persisted on repeat imaging study at least 4 weeks after initial documentation of response. CR was defined as disappearance of all lesions (target and/or non target). PR were those with at least 30 percent decrease in sum of the longest dimensions of target lesions taking as a reference the baseline sum longest dimensions, with non target lesions not increased or absent.

CR was defined as disappearance of all lesions (target and/or non target). PR were those with at least 30 percent decrease in sum of the longest dimensions of target lesions taking as a reference the baseline sum longest dimensions, with non target lesions not increased or absent. Progression was defined as >= 20 percent increase in sum of longest diameter of target lesions; measurable increase in non-target lesion; appearance of new lesions.

    PFS (as per Response Evaluation Criteria in Solid Tumors [RECIST] version 1.1) was defined as the time (in months) from start of study treatment to first documentation of objective tumor progression or death due to any cause, whichever occurred first. PFS (in months) was calculated as (first event date minus date of first dose of study medication plus 1) divided by 30.44. Progression was defined as >= 20 percent increase in sum of longest diameter of target lesions; measurable increase in non-target lesion; appearance of new lesions. PFS was not estimated in Dose Expansion Cohort 2 due to small sample size.

    Percentage of c-MET positive tumor cell for objective response (complete response [CR] + partial response [PR]) is reported. Objective response was defined as CR and PR. CR was defined as disappearance of all lesions (target and/or non target). PR were those with at least 30 percent decrease in sum of the longest dimensions of target lesions taking as a reference the baseline sum longest dimensions, with non target lesions not increased or absent. Biomarker analysis was not planned to be performed in dose escalation part and Cohort 2 of dose expansion part, as pre-specified in protocol.

  22. Dose Expansion Part Cohort 1: Level of Plasma Soluble Protein Biomarker (c-MET) [ Time Frame: Baseline; Day 1 and 15 of Cycle 1; Day 1 of Cycles 2, 3, 5; end of treatment (up to 33 cycles in Part 1 and 17 cycles in Part 2, each cycle 28 days) ]
    Plasma soluble protein biomarker included c-MET. Biomarker analysis was not planned to be performed in dose escalation part and Cohort 2 of dose expansion part, as pre-specified in protocol.
