A Study in Leukemia Patients With Karonudib

• Status: Recruiting
• Trial end date: 2022-06-30
• Target enrollment: 0
• Participant gender: All

Summary

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.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No
