Eligibility Criteria
Inclusion Criteria:
Dose Escalation and Expansion Stages:
- ECOG performance status ≤ 1 for LPM patients, ≤ 2 for AML patients
- Age 18 years or older
- Adverse events (AEs), except for alopecia, from any previous treatments must have recovered to eligibility levels from prior toxicity
- Adequate renal, hepatic and coagulation function, as specified per protocol
- Written informed consent granted prior to any study-specific screening procedures
LPM Patients:
- Histologically confirmed lymphoproliferative malignancy
- Have received prior protocol-specified disease-dependent prior treatments
- Have measurable disease
- Platelets ≥ 75,000/µL (≥50,000/µL if bone marrow involvement), absolute neutrophil count (ANC) ≥ 1,000/ µL, and hemoglobin (Hgb) ≥ 8 g/dL
- Patients must have been off previous anticancer therapy for at least 3 weeks or 5 half-lives, whichever is longer, and the subject must have recovered to eligibility levels from prior toxicity
AML:
- Refractory or relapsed AML patients, without curative intent, e.g., not a stem cell transplant candidate
- Any prior chemotherapy must have been completed ≥ 2 weeks, any therapy with biologics must have been completed ≥ 4 weeks prior to day 1 of study treatment, and the participant must have recovered to eligibility levels from prior toxicity
- Blast count ≤ 10,000/µL prior to initiation of therapy
Exclusion Criteria
Dose Escalation and Expansion Stages:

- Prior allogeneic hematopoietic cell transplant
- Chronic graft versus host disease
- Known, active fungal, bacterial, and/or viral infection
- Uncontrolled autoimmune hemolytic anemia or thrombocytopenia
- Current subdural hematoma
- CNS or leptomeningeal metastases
- Requirement for medications or agents known to be sensitive CYP3A4 substrate drugs, CYP3A4 substrate drugs with a narrow therapeutic range or to be strong inhibitors/inducers of CYP3A4
- Requirement for immunosuppressive agents
- Evidence of significant cardiovascular disease or significant screening ECG abnormalities
- Any medical conditions that, in the Investigator's opinion, would impose excessive risk to the patient.
AML patients:
- Acute promyelocytic leukemia (APL)
- Chronic myeloid leukemia (CML) in blast crisis
