E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to demonstrate that epoetin alfa treatment reduces the proportion of anemic subjects with IPSS Low or Intermediate 1 risk MDS who require any transfusion, compared with placebo, through Week 48. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives include both efficacy and safety endpoints and are as follows: To compare the time to first transfusion after Day 28, the time to transfusion dependence, as defined by the 2006 IWG criteria after Day 28, the erythroid response rate using 2006 IWG criteria at Week 24 and Week 48, the cumulative number of RBC units transfused per subject through Weeks 24 and 48, a lack of erythropoietin accumulation after treatment with epoetin alfa once every week for 48 weeks To assess the long-term safety of epoetin alfa treatment measured by a composite endpoint of time to MDS progression (see Attachment 7), AML, or death, the individual components of safety endpoints, including time to MDS progression (see Attachment 7), time to AML, and overall survival, progression free survival, the proportion of subjects with a TVE, the proportion of subjects whose disease progresses to AML by Week 52 and at the time of clinical cutoff

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Subjects must satisfy the following criteria to be enrolled in the study: 1. Male or female at least 18 years of age. 2. Diagnosis of MDS according to WHO or FAB pathologic classification via bone marrow studies performed within 12 weeks before randomization. 3. Documentation of an IPSS score indicating Low- or Intermediate-1 risk disease, based on bone marrow studies, including cytogenetics and peripheral blood counts, performed within 12 weeks before randomization. 4. Screening hemoglobin concentration of 10.0 g/dL or less. The screening hemoglobin concentration is defined as the average of at least 2 measurements taken at least 1 week apart during the 2-week period before randomization and not influenced by RBC transfusion (i.e., no RBC transfusions within 1 week before hemoglobin measurement). 5. A baseline hemoglobin measurement collected within 24 hours prior to the first dose of study drug must measure 10.5 g/dL or less. 6. Has not been transfusion dependent at any time during the previous 6 months before randomization. A subject is considered to be transfusion dependent if he or she has received 4 or more RBC units for MDS-related anemia during a consecutive 8-week period (2006 IWG criteria). 7. Baseline serum erythropoietin concentration of less than 500 mU/mL. 8. Adequate iron stores, defined as serum ferritin greater than 100 ng/mL or transferrin saturation greater than 20% or both, measured within the 14-day screening period or adequate iron stores as demonstrated by recent (within 12 weeks) bone marrow examination with iron stain. 9. Documentation of adequate vitamin B12 and folate levels (above the lower limit of the reference range for the laboratory performing the assay), as measured within 12 weeks before randomization. 10. Adequate hematologic function, defined as an absolute neutrophil count of at least 1,000/mm3 and a platelet count of at least 50,000/mm3, not influenced by platelet transfusions within the previous 3 days. 11. Life expectancy of at least 12 months (12 months or longer). 12. ECOG performance status of 0, 1 or 2 (Attachment 4). 13. Female subjects with reproductive potential must be surgically sterile, abstinent, or practicing an effective method of birth control (e.g., prescription oral contraceptives, contraceptive injections, intrauterine device, double-barrier method [spermicidal jelly or foam with condoms or diaphragm], contraceptive patch, male partner sterilization) before entry and throughout the study and have a negative serum or urine beta human chorionic gonadotropin (β-hCG) pregnancy test at screening. 14. Willingness to adhere to the prohibitions and restrictions specified in this protocol. 15. Subjects (or their legally acceptable representatives) must sign an informed consent document indicating that they understand the purpose of and procedures required for the study and are willing to participate in the study. 16. Subjects who agree to participate in DNA pharmacogenomic research (or their legally acceptable representatives) must sign an informed consent indicating willingness to participate in the pharmacogenomic component of the study, where local regulations permit. Refusal to consent for this component does not exclude a subject from participation in the clinical study.

E.4 | Principal exclusion criteria |
1. Anemia attributed to factors other than MDS (including iron deficiency, vitamin B12 or folate deficiencies, hemolysis, chronic renal failure, or gastrointestinal bleeding). 2. Secondary MDS (MDS arising after chemotherapy, immunotherapy or radiation therapy/exposure). 3. Proliferative (WBC of at least 12,000/mm3) chronic myelomonocytic leukemia (CMML) or atypical chronic myelogenous leukemia (CML). 4. Active malignancy within the past year except basal cell or squamous cell skin cancer or carcinoma in situ of the cervix or breast. 5. Known history of HIV Type 1 seropositivity. 6. History (within 12 months) of deep venous thrombosis (includes proximal and distal), pulmonary embolism, or other venous thrombosis. Prior superficial thrombophlebitis is not an exclusion criterion. 7. History (within 6 months) of cerebrovascular accident (includes ischemic, embolic, and hemorrhagic cerebrovascular accident), transient ischemic attack, acute coronary syndrome (including myocardial ischemia, unstable angina, Q wave myocardial infarction, non-Q wave myocardial infarction), or other arterial thrombosis. 8. Currently receiving therapeutic anticoagulants (prophylactic anticoagulants are acceptable). 9. Uncontrolled hypertension (defined as a systolic pressure of 160 mmHg or higher or a diastolic pressure of 110 mmHg or higher or both). 10. New onset seizures (within 3 months before randomization) or poorly controlled seizures. 11. Clinically significant, uncontrolled disease or dysfunction of the pulmonary, cardiovascular, endocrine, neurologic, gastrointestinal, or genitourinary systems not attributable to MDS. 12. Pregnancy or breast feeding. 13. Known hypersensitivity to mammalian-cell derived products or to human albumin. 14. Prior or concurrent treatment with epoetin alfa or any other approved or experimental ESA (e.g., epoetin beta, darbepoetin), within the previous 12 months before randomization. 15. Use of experimental agents or devices for any reason within the previous 8 weeks before randomization. 16. Prior use of any approved or experimental agent for the treatment of MDS (e.g., cytotoxic chemotherapeutic agents, thalidomide, lenalidomide, tipifarnib, lonafarnib, azacitidine, decitabine, and danazole). 17. Prior (within the previous 2 weeks) or concurrent treatment with G-CSF or granulocyte-macrophage colony-stimulating factor (GM-CSF) for the treatment of neutropenia. 18. Major infection requiring hospitalization and antibiotics within 2 weeks before randomization. 19. Major surgery within 4 weeks before randomization or planned major surgery before Week 52. 20. Planned stem cell harvest of bone marrow or high-dose chemotherapy with stem cell transplantation before Week 52. 21. Previous bone marrow or stem cell transplantation. 22. Employees of the investigator or study center, with direct involvement in the proposed study or other studies under the direction of that investigator or study center and family members of the employees or the investigator.

E.5 End points |
E.5.1 | Primary end point(s) |
Selection of a transfusion based variable as the primary endpoint reflects the currently accepted clinically meaningful outcome for registration studies of erythropoietic agents. The proportion of subjects who remain transfusion free from Day 29 through Week 48 was selected as the primary efficacy endpoint to account for the lag time between the start of erythropoietin treatment and its effect on hematopoiesis. |
