- •4. Anemia, defined as:
- •a. Mean hemoglobin concentration < 10.0 g/dL of 2 measurements (one performed within one day prior to Cycle 1 Day 1 and the other performed during the screening period [Day -28 to Day -1]) in non-transfusion-dependent patients, defined as having received < 4 units of RBCs within 8 weeks prior to Cycle 1 Day 1, OR
- •b. Transfusion-dependent, defined as requiring = 4 units of RBCs every 8 weeks (confirmed over 6 months prior to Cycle 1 Day 1).

Males must agree to use a latex condom during any sexual contact with females of child-bearing potential while participating in the study and for 12 weeks following the last dose of ACE-536, even if he has undergone a successful vasectomy. Patients must be counseled concerning measures to be used to prevent pregnancy and potential toxicities prior to the first dose of ACE-536.
