Inclusion Criteria:

- Hospitalized male and female patients, 18 years of age or older

- Patients who have leukemia (acute lymphocytic leukemia [ALL], acute myelogenous
leukemia [AML], chronic lymphocytic leukemia [CLL], chronic myelogenous leukemia
[CML]), that is newly diagnosed, who have had initial induction, re-induction, or

(refractory anemia [RA], refractory anemia with ringed sideroblasts [RARS],
refractory anemia with excess blasts [RAEB], refractory anemia with excess blasts in
transformation to leukemia [RAEB-T], or chronic myelomonocytic leukemia [CMML].

- Fever, defined as an oral temperature of ≥ 37.9°C /100.2°F, a rectal temperature ≥
38.4°C /101.4°F, or a tympanic temperature ≥ 38°C /100.4°F

Exclusion Criteria:

- The presence of any clinically acute or chronic disease or condition that, in the
opinion of the investigator, may interfere with the patient's ability to safely
comply with the conditions of the protocol, or could preclude the evaluation of the
patient's response or could make the completion of the therapy unlikely

- Neutropenia associated with syndromes that are not associated with a high risk of
bacterial infection (eg. chronic benign neutropenia or Kostmann's syndrome)

- Neutropenia due to primary bone marrow failure
