- Incidence of dose-limiting toxicities (DLTs) of CPI-006 as a single agent and in combination with ciforadenant and with pembrolizumab. [ Time Frame: From start of treatment to end of treatment, up to 36 months ]
- Incidence of treatment-emergent adverse events as assessed by NCI CTCAE v.4.03, of CPI-006 as single agent and in combination with ciforadenant and with pembrolizumab. [ Time Frame: From start of treatment to end of treatment, up to 36 months ]
- Identify the MDL(maximum dose level) of single agent CPI-006 [ Time Frame: From start of treatment to end of treatment, up to 36 months ]
- Area under the curve (AUC) of CPI-006 [ Time Frame: Day 1, 2, 8 , and 15 of Cycle 1 & 4 (each cycle is 21 days). ]
- Maximum serum concentration (Cmax) of CPI-006 [ Time Frame: Day 1, 2, 8 , and 15 of Cycle 1 & 4 (each cycle is 21 days). ]
- Objective response rate per RECIST v.1.1 criteria of CPI-006 as single agent and in combination with ciforadenant and with pembrolizumab. [ Time Frame: From start of treatment to end of treatment, up to 36 months ]
