A Phase Ib/II Multicenter Open-label Study of BGB324 as a Single Agent and in Combination With Cytarabine or Decitabine in Patients With Acute Myeloid Leukemia or as a Single Agent in Patients With Myelodysplastic Syndrome

A Phase Ib/II multicentre open label study of BGb324 as a single agent in patients with AML
or MDS or in a combination with cytarabine and decitabine in AML patients.

BGB324 is a potent selective small molecule inhibitor of Axl, a surface membrane protein
kinase receptor which is overexpressed in up to half of AML cases.

This study is a dose-escalation of BGB324, an Axl kinase inhibitor, in patients with acute
myeloid leukemia (AML) and myelodysplastic syndrome (MDS), followed by a cohort expansion
study of BGB324 either as a single agent in patients with AML or MDS, or in combination with
cytarabine (cytosine arabinoside, Ara-C) or decitabine in patients with AML.

The study will run in Germany, Norway and the US and may enrol up to approximately 75
patients with AML or MDS.

The study consists of a dose-escalation phase to determine the MTD and/or recommended dose
for Phase II (RP2D) of BGB324 in patients with relapsed or refractory AML or MDS (Part A)
followed by a cohort expansion phase in up to four disease-specific cohorts (Part B).

BGB324 will be administered orally according to a daily schedule, with the first three doses
of Cycle 1 serving as a 'loading' dose. Each 21-day (three week) period will constitute 1
cycle of treatment.

Inclusion Criteria:

1. Provision of signed written informed consent

2. Histological, molecular or cytological confirmation of:

Part A:

- AML (with the exception of AML M3), patients with relapsed or refractory AML
following treatment with cytotoxic chemotherapy or a targeted or biologic agent

- high risk group MDS, according to IPSS Risk Stratification (Norway Only)

Part B:

- AML (with the exception of AML M3):

- AML unsuitable for intensive chemotherapy

- newly diagnosed AML unsuitable for intensive chemotherapy

- MDS:

- high/intermediate (int-2) risk group MDS, according to IPSS Risk Stratification
(Norway Only)

- patients with previously treated MDS (with the exception of deletion 5q MDS) (US
only)

3. Age 18 years or older

4. Female patients of childbearing potential must have a negative serum pregnancy test
within 3 days prior to taking their first dose of BGB324. Male patients and female
patients of reproductive potential must practice highly methods of contraception
throughout the study and for ≥ 3 months after the last dose of BGB324.

5. Eastern Cooperative Oncology Group (ECOG) performance status 0, 1 or 2

Exclusion Criteria:

1. Patients who have a matched donor and are candidates for allogeneic bone marrow
transplantation

2. Pregnant or lactating

3. Abnormal left ventricular ejection fraction (less than the lower limit of normal for
a patient of that age at the treating institution or <45%, whichever is lower).

4. Congestive cardiac failure of >Grade 2 severity according to the NYHA defined as
symptomatic at less than ordinary levels of activity

5. Unstable cardiac disease, including unstable angina or unstable hypertension, or need
to change medication within 6 weeks of provision of consent due to lack of disease
control

6. Ischemic cardiac event including myocardial infarction within 3 months prior to first
dose

7. Current treatment with any agent known to cause Torsades de Pointes which cannot be
discontinued at least five half-lives or two weeks prior to the first dose of study
treatment.

8. Treatment with any of the following; histamine receptor 2 inhibitors, proton pump
inhibitors or antacids within 3 days or 5 half-lives of administration of BGB234,
whichever is longer.

9. Treatment with any medication which is predominantly metabolized by CYP3A4 and has a
narrow therapeutic index.

10. Radiotherapy or chemotherapy within the 14 days prior to the first dose of BGB324
being administered (other than hydroxyurea)

11. Active, uncontrolled central nervous system (CNS) disease including CNS leukemia

12. Major surgery within 28 days prior to the start of BGB324 - excluding skin biopsies
and procedures for insertion of central venous access devices

13. Prior exposure to Astellas ASP2215.

14. Unresolved CTCAE >Grade 2 toxicity (other than stable toxicity) from previous
anti-cancer therapy excluding alopecia.
