Arms Assigned Interventions
Experimental: Dinaciclib Drug: Dinaciclib
Dinaciclib administered intravenously over 2 hours at a dose of 7 mg/m^2 on Day 1, 10 mg/m^2 on Day 8, and 14 mg/m^2 on Day 15 in Cycle 1. Starting in Cycle 2 and thereafter, dinaciclib will be dosed at 14 mg/m^2 on Days 1, 8, and 15 of each 28-day cycle for a total of 12 cycles.
