Low Dose GroupEXPERIMENTALPhase 1: Cohorts 1 \& 2 will consist of 4 female and 4 male patients enrolled concurrently who will be randomized 3:1 to receive CM4620-IE plus standard of care versus standard of care alone. Planned doses for patients who are randomized to receive CM4620-IE are 1.0 mg/kg on Days 1 and 1.4 mg/kg on Days 2-4.
High Dose GroupEXPERIMENTALPhase 2: Cohorts 3 \& 4 will consist of 8 female and 8 male patients enrolled concurrently who will be randomized 3:1 to receive CM4620-IE plus standard of care versus standard of care alone. Planned doses for patients who are randomized to receive CM4620-IE are 2.08 mg/kg of CM4620-IE on Days 1 and 2, and 1.6 mg/kg on Days 3 and 4.
Standard of CareNO_INTERVENTIONFor all cohorts, patients will be randomized 3:1 to CM4620-IE plus standard of care versus standard of care alone.
