  • Subject must have at least one measurable lesion according to RECIST Version1.1.
  • Eastern Cooperative Oncology Group (ECOG) Performance Score of 0 or 1.
  • Available archived tumor tissue sample to allow for correlative biomarker studies. If unavailable or unsuitable, the subject must consent and undergo fresh tumor biopsy.
  • Adequate organ function.
  • Subjects with central nervous system (CNS) metastases must have been treated, be asymptomatic.
  • Females of childbearing potential and non-sterilized males who are sexually active must use an effective method of contraception from screening until 120 days after final dose of investigational product or women of non child bearing potential.
