A Study in Leukemia Patients With Karonudib

Recruiting now · Phase 1

Conditions studied: Leukemia

In brief

The primary objective of this study is to determine safety and tolerability of Karonudib for the treatment of hematological malignancies. Secondary objectives are to determine a recommended RP2D and schedule for further development of Karonudib, to determine the pharmacokinetics of Karonudib, to look for evidence of treatment efficacy. Overall survival will also be recorded.
