7. Participants with MDS/MPN including CMML who have clinical extramedullary disease including clinically palpable hepatomegaly or splenomegaly.
8. Has previous treatment with more than 1 cycle of decitabine, azacitidine, or guadecitabine (Phases 2 and 3 only).
9. Has been treated with any investigational drug or therapy within 2 weeks, or 5 half-lives, whichever is longer, before the protocol-defined first dose of study treatment, or ongoing clinically significant adverse events from previous treatment with investigational drug or therapy.
