The purpose of this study is to understand the safety, tolerability, efficacy, pharmacokinetic (PK), pharmacodynamic (PD), and preliminary efficacy of orally administered AZD3632 in participants with advanced haematologic malignancies with KMT2Ar, NPM1m, or other genotypes associated with homeobox (HOX) overexpression.

Detailed Description

This is a first in human (FTiH), open-label, multi-centre study of AZD3632 in participants with relapsed or refractory acute leukaemia or myelodysplastic Syndromes (MDS) with HOX overexpression genotypes.

This study includes multiple modules (module 1 and module 2) each investigating AZD3632 in a specific population and/or in combination with other anticancer agents.

Module 1 is a dose escalation of AZD3632 monotherapy. Module 2 will investigate the safety, PK, and tolerability when co-administered with posaconazole.
