Incidence of dose limiting toxicities (DLTs), treatment-emergent adverse events (TEAEs), and/or changes in clinical laboratory abnormalities.

Cohort 1: Determine the dose(s) of CTX-10726 to be further examined in Cohort 2 and Phase 2 studies
From first dose of CTX-10726 (Cycle 1 Day 1, Cycle = 2 weeks ) until 30 days after the last dose of CTX-10726 (average of 6 months)
Cohort 2: Evaluate the safety and tolerability of CTX-10726 by incidence of treatment-emergent adverse events (TEAEs) at dose(s) selected from Cohort 1
