Participating in This Clinical Trial

Inclusion Criteria

  • Subject has provided informed consent prior to initiation of any study specific activities/procedures.
  • Age greater than or equal to 18 years old at the time of signing informed consent.
  • Life expectancy of greater than 3 months, in the opinion of the investigator
  • Subject must have histologically or cytologically confirmed metastatic or locally advanced solid tumors not amenable to curative treatment with surgery or radiation.
  • At least 1 measurable as defined by modified RECIST 1.1 which has not undergone biopsy within 3 months of the screening scan. This lesion cannot be biopsied at any time during the study. Note: if there is only one lesion available for biopsy and radiographic assessment, it may be permitted to be biopsied after discussion with sponsor.
  • Subjects with treated brain metastases are eligible provided they meet the following criteria: Definitive therapy was completed at least 2 weeks prior to enrollment. No evidence of radiographic CNS progression or CNS disease following definitive therapy and by the time of study screening. Patients manifesting progression in lesions previously treated with stereotactic radiosurgery may still be eligible if pseudoprogression can be demonstrated by appropriate means and after discussion with the medical monitor.
  • Any CNS disease is asymptomatic, any neurologic symptoms due to CNS disease have returned to baseline or are deemed irreversible, the patient is off steroids for at least 7 days (physiologic doses of steroids are permitted), and the patient is off or on stable doses of anti-epileptic drugs for malignant CNS disease.
  • Eastern Cooperative Oncology Group (ECOG) Performance Status of less than or equal to 2.
  • Hematologic function, as follows without growth factor support within 2 weeks prior to study day 1: Absolute neutrophil count (ANC) greater than or equal to 1.0 x 10E9/L; Platelet count greater than or equal to 75 x 10E9/L; Hemoglobin greater than or equal to 9 g/dL (90 g/L).
  • Adequate renal laboratory assessments, as follows: Estimated glomerular filtration rate based on MDRD (Modification of Diet in Renal Disease) calculation . 60 ml/min/1.73 m2 for Cohorts 1, 2, 4, and 5.

Estimated glomerular filtration rate based on MDRD (Modification of Diet in Renal Disease) calculation . 45 ml/min/1.73 m2 for Cohorts 3, 6, 7, 8 and 9.

  • Hepatic function, as follows: Total bilirubin less than or equal to 1.5 x ULN or less than or equal to 3 x ULN for subjects with liver metástasis; AST less than or equal to 3 x ULN or less than or equal to' 5 x ULN for subjects with liver metástasis; ALT less than or equal to 3 x ULN or less than or equal to 5 x ULN for subjects with liver metástasis; lkaline phosphatase less than or equal to 2.5 x ULN or less than or equal to 5 x ULN for subjects with liver metastasis.
  • Subjects enrolled to Cohorts 7-9, must submit tumor. Fresh tumor biopsies may be performed if subject has a readily accessible tumor lesion and who consent to the biopsies. If fresh biopsies cannot be obtained, archival tumor samples <1 year from screening date.
