Inclusion Criteria:

• Males and/or females over age 18.
• Subject has morphologically documented relapsed or refractoryprimary AML as defined by the World Health Organization (WHO) 2016 criteria for which no established standard therapy is available.
• ECOG performance status of 0 to 2.
• Persistent chronic clinically significant non-hematological toxicities from prior treatment (including chemotherapy, kinase inhibitors, immunotherapy, experimental agents, radiation, HSCT, or surgery) must be Grade ≤ 1.
• Any anti-tumor treatment with radiation therapy, surgery, or immunotherapy wihtin 2 weeks prior to trial entry.
• Life expectancy of at least 3 months.

Exclusion Criteria:

• Disease diagnosis of acute promyelocytic leukemia.
• Medical history of difficulty swallowing, malabsorption or other chronic gastrointestinal disease, or conditions that may hamper compliance and/or absorption of the tested product.
• Previously treated malignancies other than the current disease, except for adequately treated non-melanoma skin cancer, in situ cancer, or other cancer from which the subject has been disease-free for at least 5 years at the trial entry.
• Laboratory values not within the Protocol-defined range.
• Concomitant disease or condition that could interfere with the conduct of the trial, or that would, in the opinion of the Investigator, pose an unacceptable risk to the subject in this trial.
