  • platelet count greater than or equal to 100 times 10^9/L
  • hemoglobin >= 9 g/dL without red blood cell (RBC) transfusion within 7 days prior to the first dose of study treatment
  • aspartate aminotransferase (AST) and alanine aminotransferase (ALT) less than 3 times the upper limit of normal (ULN) (or less than 5 times ULN if liver involvement). Total bilirubin less than 1.5 times ULN (or less than 2 times ULN if liver involvement); with the exception of participants with Gilbert's disease)
  • calculated or measured creatinine clearance (CrCl) of >= 30 mL/minute calculated using the formula of Cockcroft and Gault ([140 - Age]) x Mass [kg]/[72 x Creatinine mg/dL]) (x 0.85 if female)
  • international normalized ratio (INR) or prothrombin time (PT) less than 1.5 times ULN except for participants receiving anticoagulation, who must be on a stable dose of anticoagulant therapy for 6 weeks prior to enrollment

排除标准

  • Prior treatment for metastatic or unresectable disease (Note: prior adjuvant, neo-adjuvant and peri-operative therapy is allowed if completed more than 6 months prior to first dose of study treatment)
  • Prior treatment with any selective inhibitor of fibroblast growth factor - fibroblast growth factor receptor (FGF-FGFR) pathway
  • Known human epidermal growth factor receptor 2 (HER2) positive
  • Untreated or symptomatic central nervous system (CNS) disease or brain metastases
  • Peripheral sensory neuropathy greater than or equal to Grade 2
  • Clinically significant cardiac disease
  • Other malignancy within the last 2 years (exceptions for definitively treated disease)
  • Chronic or systemic ophthalmological disorders
  • Major surgery or other investigational study within 28 days prior to first dose of study treatment
  • Palliative radiotherapy within 14 days prior to the first dose of study treatment
  • Evidence of or recent history (within 6 months) of corneal defects, corneal ulcerations, keratitis, or keratoconus, history of corneal transplant, or other known abnormalities of the cornea that may pose an increased risk of developing a corneal ulcer.
