Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Primary Objective Part I

* To determine the safety and tolerability of Karonudib in escalating doses for the treatment of patients with advanced relapsed/refractory Acute Myeloid Leukemia (AML), Acute Lymphoblastic Leukemia (ALL) , Diffuse Large B-Cell Lymphoma, Multiple Myeloma (MM) and high-risk Myelodysplastic Syndrome (MDS)AML, ALL, DLBCL, Burkitt´s lymphoma, multiple myeloma and high-risk MDS Primary Objective Part II
* To determine the safety and tolerability of Karonudib in combination with standard of care treatment, Idarubicinother anti-cancer agents for the treatment of patients with advanced progressive, relapsed/refractory AML, and high-risk MDS

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Dose escalation

Karonudib is an oral inhibitor of MTH1 and will be supplied as an oral solution to be taken every other day. There are three planned dose cohorts. Patients will be given every second day dosing.

Group Type EXPERIMENTAL

Karonudib

Intervention Type DRUG

First part of the study - four different dose cohorts Extension part of the study - karonudib BID (twice a week) and Idarubicin days 1-3.
