Summary:

      This is a phase I, open-label, dose-escalation trial of defactinib (VS-6063), a focal
      adhesion kinase inhibitor, in Japanese patients with non-hematologic malignancies. The
      purpose of this study is to assess the safety (including the recommended phase 2 dose), the
      pharmacokinetics, and the anti-cancer activity of defactinib (VS-6063).

             treatment.

          -  Predicted life expectancy of ≥ 3 months.

          -  Adequate renal function [creatinine ≤ 1.5x ULN (upper limit of normal)] or GFR of ≥
             50mL/min.

          -  Adequate hepatic function (total bilirubin ≤ 1.5x ULN for the institution; AST
             [aspartate transaminase] and ALT [alanine transaminase] ≤ 3x ULN, or ≤ 5x ULN if due
             to liver involvement by tumor).

             absolute neutrophil count ≥ 1.5x109 cells/L).

          -  Corrected QT interval (QTc) < 470 ms (as calculated by the Fridericia correction
             formula).

          -  Negative pregnancy test for women of child-bearing potential. (A woman of childbearing
             potential is defined as one who is biologically capable of becoming pregnant except
             for women who have undergone permanent contraceptive surgery or are postmenopausal
             (defined as the absence of menstruation for at least 12 months without other medical
             reasons).

          -  Men and women of child bearing potential must agree to use adequate birth control
             throughout their participation in the study and for 90 days following the last study
             treatment.

             dose of steroids/ anticonvulsants, with no dose change within 28 days prior to the
             first dose of study drug, will be allowed.

          -  Subjects with known infection with human immunodeficiency virus (HIV) or Acquired
             Immune Deficiency Syndrome (AIDS) (testing not required).

          -  Subjects being actively treated for a secondary malignancy.

          -  Cancer-directed therapy (chemotherapy, radiotherapy, hormonal therapy, biologic or
             immunotherapy, etc.) within 28 days of the first dose of study drug or 5 half-lives,

             investigational drug and administration of the study treatment is required. In
             addition, any drug-related toxicity except alopecia should have recovered to grade 1
             or less.
