disease progression, or not met the criteria for treatment with Gilteritinib in the

tests:

a. Serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =2.5 ×
upper limit of normal (ULN) b. Serum total bilirubin =1.5 × ULN unless due to
Gilbert's disease c. Estimated glomerular filtration (eGFR) rate of >50 mL/min as
calculated by the Modification of Diet in Renal Disease equation.

9. Female patients:

a. If of non-childbearing potential i.e., surgically sterilized (hysterectomy,
bilateral salpingectomy, bilateral oophorectomy) at least 6 weeks before the Screening
visit or postmenopausal (where postmenopausal is defined as no menses for 12 months
without an alternative medical cause and a follicle-stimulating hormone (FSH) level
consistent with postmenopausal status, per local laboratory guidelines), or b. If of
childbearing potential, must: i. Have a negative serum pregnancy test at the Screening
visit and urine pregnancy test on admission to the clinic on Day-1.

ii. Agree not to attempt to become pregnant or donate ova from signing the consent form
until at least 45 days after the last dose of study drug.

iii. Agree to use adequate contraception (defined as use of a condom by the male partner
combined with use of a highly effective method of contraception from Screening until at
least 45 days after the last dose of study drug, if not exclusively in a same-sex
relationship or abstinent as a committed lifestyle).

10. Male patients and their female spouse/partners who are of childbearing potential must
agree to use highly effective contraception consisting of 2 forms of birth control (at
least 1of which must be a barrier method) starting at Screening and continue throughout the
study period and for 45 days after the final study drug administration. Male patient must
not donate sperm starting at Screening and throughout the study period and for 45 days
after the final study drug administration.

Exclusion criteria

1. Diagnosis of isolated myeloid sarcoma (meaning, patients must have blood or marrow
involvement with AML)

2. Acute promyelocytic leukemia (FAB M3)

3. Active central nervous system (CNS) involvement by AML

4. Clinical signs/symptoms of leukostasis requiring urgent therapy

5. Known active infection with Human Immunodeficiency Virus (HIV), hepatitis B or
hepatitis C. Patients with a history of positive serology for hepatitis B or C require
a negative Polymerase chain reaction (PCR) test for virus to go onto therapy

6. Disseminated intravascular coagulopathy with active, unmanageable bleeding or signs of
thrombosis.

7. Patients who have received an investigational agent (for any indication) within 5
half-lives of the agent; if the half-life of the agent is unknown, patients must wait
1 week prior to first dose of study treatment. An investigational agent is one for
which there is no approved indication by the local regulatory authority.

8. Systemic antineoplastic therapy within 5 half-lives or radiation therapy within 1 week
prior to starting protocol with the exception of hydroxyurea, which is allowed to
control white blood cell counts.

9. Female patients who are pregnant or lactating

10. Patients with psychological, familial, social, or geographic factors, other
significant medical condition, laboratory abnormality that otherwise preclude them
from giving informed consent, following the protocol, potentially hamper compliance
with study treatment and follow-up or would confound the interpretation of the results
of the study.

11. Patients with the following will be excluded: uncontrolled intercurrent illness
including, but not limited to, symptomatic congestive heart failure, unstable angina
pectoris, serious cardiac arrhythmia, myocardial infarction with evidence of residual
abnormalities within 6 months prior to enrollment (Troponin (regular or high
sensitivity) leak alone not included if no residual dysfunction), New York Heart
Association (NYHA) Class III or IV heart failure, severe uncontrolled ventricular
arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction
system abnormalities. Patients with medical comorbidities that will preclude safety
evaluation of the combination should not be enrolled.

12. Infection is a common feature of AML, patients with active infection are permitted to
enroll provided that the infection is under control in the opinion of the
Investigator. Patients with uncontrolled infection shall not be enrolled until
infection is treated and brought under control.
