Bioequivalence & Food Effect Study in Patients With Solid Tumor or Hematologic Malignancies

Stage I - Pharmacokinetics (Bioequivalence)

Subjects will be randomized to receive CC-486 300 mg orally on each of the two
pharmacokinetic (PK) study days based on the dosing sequences they are randomized to:

Dosing Sequence 1: 2x150 mg tablets followed by 1x30 mg tablet. Dosing Sequence 2: 1x300 mg
tablet followed by 2x150 mg tablets. Each dose will be administered in the clinic at least 48
hours apart between PK dosing day 1 and PK dosing day 2 over a period no longer than 10 days
under fasted conditions.

Stage II - Pharmacokinetics (Food Effect)

Subjects will be randomized to receive CC-486 300 mg orally on each of the two PK study days
based on the dosing sequences they are randomized to:

Dosing Sequence 1: 1x300 mg tablet under fasted condition followed by 1x300 mg tablet under
fed condition.

Dosing Sequence 2: 1x300 mg tablet under fed condition followed by 1x300 mg tablet under
fasted condition.

Each dose will be administered in the clinic at least 48 hours apart between PK dosing day 1
and PK dosing day 2 over a period no longer than 10 days. The sponsor will generate the
randomization scheme and assign subjects upon enrollment to the appropriate sequence for
dosing:

Fasted condition: following an overnight fast of at least 10 hours, subjects will ingest oral
Azacitidine with 240 mL of room temperature water. Subjects must fast for a minimum of 4
hours following oral Azacitidine administration. Subjects may drink water as desired, except
for 1 hour before and 1 hour after oral Azacitidine administration.

Fed condition: following an overnight fast of at least 10 hours and following the performance
of all required pre-dose assessments, subjects randomized to receive test medication in a fed
state will begin ingesting a breakfast meal 30 (±5) minutes prior to the planned
administration of oral Azacitidine. They will continue the entire meal within 20 to 25
minutes (no less than 20 minutes) from the time the meal is served. Subjects will then ingest
oral Azacitidine with 240 mL of room temperature water. Subjects must fast a minimum of 4
hours following oral Azacitidine administration. Subjects may drink water as desired, except
for 1 hour before and 1 hour after administration of oral Azacitidine.

Extension Phase (for subjects who have completed PK Stage I or Stage II) Subjects continuing
beyond the pharmacokinetics phase (Stage I or Stage II) will enter the extension phase of the
study at the discretion of the investigator to receive < 6 (four-week) cycles of Vidaza 75
mg/m2 IV or SC daily for 7 days in the clinic and repeat every 4 weeks per prescribed label
at the discretion of the investigator for ≤ 6 (four-week) cycles.

Inclusion Criteria:

- Subjects must satisfy the following criteria to be enrolled in the study:

1. Age ≥ 18 years of age at the time of signing the informed consent document.

2. Understand and voluntarily sign an informed consent document prior to any study
related assessments/procedures are conducted.

3. Documented diagnosis of any of the following:

1. Myelodysplastic Syndrome (MDS) according to the World Health Organization
(WHO) 2008 classification

2. Acute myeloid leukemia (AML)

3. Multiple myeloma (MM), limited to those patients for whom standard curative
or palliative treatments do not exist or are no longer effective

4. Non-Hodgkin's lymphoma (NHL), limited to those patients for whom standard
curative or palliative treatment do not exist or are no longer effective,

5. Hodgkin's lymphoma (HL), limited to those patients for whom standard
curative or palliative treatment do not exist or are no longer effective

6. Metastatic or inoperable solid tumors* (except gastrointestinal tumors or
tumors that originated or metastasized to the liver) for which no standard
treatment exists, or have progressed or recurred following prior therapy.

- Subjects must not be eligible for therapy of higher curative potential
where an alternative treatment has been shown to prolong survival in an
analogous population.

4. Patients with a history of treated brain metastases should be clinically stable
for ≥ 4 weeks prior to signing the informed consent. Glucocorticoid therapy for
central nervous system (CNS) edema is permitted if ≤ 20 mg of prednisolone (or
equivalent).

5. Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2.

6. Have a life expectancy of ≥ 3 months.

7. Have stable renal function without dialysis for at least 2 months prior to
Investigational Product (IP) administration defined by:

1. Serum creatinine < 2.5 x the upper limit of normal (ULN)

2. An average calculated creatinine clearance > 30 mL/min/1.73 m^2

8. Have organ and marrow function at the screening and pre-dose visits as defined
by:

1. Hemoglobin ≥ 8 g/dL

2. Absolute neutrophil count (ANC) ≥ 0.75 x 10^3/uL without treatment with a
myeloid growth factor within 3 days prior to first dose of IP

3. Platelets ≥ 30 x 10^3/uL

practice true abstinence throughout the study, and for 3 months following
the last dose of IP; and

- Negative serum pregnancy test at screening (sensitivity of at least 25
mIU/mL); (Note that the screening serum pregnancy test can be used as the
test prior to starting IP in the pharmacokinetics phase if it is performed
within the 72-hour timeframe), and

sensitivity of at least 25 mIU/mL) within 72 hours prior to starting IP in
