A Study of Rebastinib (DCC-2036) in Combination With Carboplatin in Patients With Advanced or Metastatic Solid Tumors

Primary Outcome Measures

• Adverse Events (Part 1 and Part 2) [Time Frame: Approximately 24 months]
• Objective response rate (ORR) (Part 2) [Time Frame: Approximately 24 months]

Secondary Outcome Measures

• Maximum observed concentration (Cmax) of rebastinib [ Time Frame: Cycle 1 Day 1, Cycle 2 Day 1 (each cycle is 21 days) ]
  Measure the Cmax
• Area under the concentration-time curve (AUC) of rebastinib [ Time Frame: Cycle 1 Day 1, Cycle 2 Day 1 (each cycle is 21 days) ]
  Measure the AUC
• Progression-free-survival (PFS) [ Time Frame: Approximately 24 months ]
  Measure of the time from Cycle 1 Day 1 to disease progression or death due to any cause
• Time to progression (TTP) [ Time Frame: Approximately 24 months ]
  Measure of the time from Cycle 1 Day 1 to the first documentation of progressive disease
• Duration of response (DOR) [ Time Frame: Approximately 24 months ]
  Measure of time from PR, CR to disease progression or death due to any cause
• Overall survival (OS) [ Time Frame: Approximately 24 months ]
  Measure of overall survival
