- Mean Change in Hemoglobin Level From Baseline to the End of Study (26 Weeks) [ Time Frame: Week 0 to Week 26 ]
- The Number of Patients Achieved a Hemoglobin Response. [ Time Frame: Week 0 to Week 26 ]Hemoglobin reponse was defined as 2 consecutive hemoglobin measurements at least 1.0 g/dL above baseline or 2 consecutive hemoglobin measurements at least 11.0 g/dL
- Time to Hemoglobin Response [ Time Frame: Week 0 to Week 26 ]Time to hemoglobin reponse was defined as the time between individual treatment start date and the first of 2 consecutive hemoglobin measurements at least 1.0 g/dL above baseline or 2 consecutive hemoglobin measurements at least 11.0 g/dL. Note: Upper 95% confidence limit for the Standard of Care Group was not estimable because an insufficient number of participates reached the event at the final time point for assessment.

Hide Detailed Description
PROCRIT (Epoetin alfa) is a brand of recombinant human erythropoietin (rHuEPO). Erythropoietin is a hormone produced in the kidney. Its function is to stimulate the production of red blood cells in the bone marrow. Many patients with Chronic Kidney Disease (CKD) do not produce enough erythropoietin and thus develop anemia (a reduction in red blood cell levels). This can cause them to feel tired.
PROCRIT (Epoetin alfa) is approved by the United States Food and Drug Administration (FDA) for the treatment of anemia (low red blood cell count) in patients with CKD (not on dialysis). The approved dosing frequency for PROCRIT (Epoetin alfa) in patients with CKD is one injection three times per week. Although PROCRIT (Epoetin alfa) is approved by the FDA for the treatment of certain types of anemia at different dosing schedules, the dosing schedules that will be used in this study are investigational in CKD. An investigational use is one that is currently not approved by the FDA.
This is an open-label, randomized (patients are assigned different treatments based on chance), multi-center, controlled study of patients with anemia of Chronic Kidney Disease (CKD), not on dialysis, who reside in long-term care facilities. Approximately 156 patients with CKD, not on dialysis, who have not received an erythropoietin receptor agonist (a drug that stimulates red blood cell production) for eight weeks immediately prior to screening (Week -1) and who have a hemoglobin (Hb, a measure of the number of red blood cells), less than 11 g/dL at screening will be eligible to participate. Patients will be evaluated for eligibility during a one-week screening phase. Eligible patients will be randomized in a 3:1 ratio to a PROCRIT (Epoetin alfa) group or to the control group for a period of 26 weeks. Randomization is done through a computer that randomly assigns the subject by chance (like rolling dice) to one of two groups (No one can choose the group to which they will be assigned.). They will have a 3 to 1 chance of being assigned to Group 1 versus Group 2, which means that out of every 4 patients entering the study 3 will receive PROCRIT (Epoetin alfa) and 1 will not.
Group 1 -will receive PROCRIT (Epoetin alfa) 20,000 Units (U) every 2 weeks until the hemoglobin reaches 11.0 g/dL or higher and remains at this level for two measurements in a row. At Week 6 or thereafter, the 20,000 Unit dose may be adjusted upward or downward as required to obtain the two consecutive hemoglobin measurements. Once the two consecutive measurements have been achieved, PROCRIT (Epoetin alfa) will be given every 4 weeks (Q4W) at double the previous dose to obtain a target hemoglobin of up to 12.0 g/dL. There will be no conversion to Q4W before Week 6 or after Week 18. If the hemoglobin drops, patients may go back to receiving PROCRIT (Epoetin alfa) every 2-weeks. If the hemoglobin rises above 12.0 g/dL, patients will not receive another dose of PROCRIT (Epoetin alfa) until the Hg level is below 12.0 g/dL. If the hemoglobin rises rapidly, patients will not receive another dose of PROCRIT (Epoetin alfa) until the rise is 1 g/dL or less in a 2-week period. The maximum amount of PROCRIT (Epoetin alfa) that this group can receive is 60,000 Units over a 4-week period. All doses of PROCRIT (Epoetin alfa) are injected under the skin (subcutaneous).
Group 2 - will not receive any PROCRIT (Epoetin alfa). This group will continue to receive the care that they are now receiving from their physician and the physician will review all lab results.
Since a lack of iron could interfere with the ability of patients to make red blood cells, patients in both groups will have iron levels checked at the screening visit and during the study. Based on the results of iron tests, the study doctor may prescribe an oral (by mouth) or intravenous (injection) iron supplement during the study. If the need for iron supplementation is determined, patients will receive iron supplementation no matter which group they are in.
Every two weeks a study visit will be performed. At each visit, blood pressure and heart rate will be checked, and blood will be drawn for all patients and sent to the central laboratory for complete blood count (CBC). The Hb by CBC will be used for efficacy analysis ( to measure the effectiveness of the study drug in increasing the hemoglobin level). Hb testing by HemoCue will be performed every two weeks on-site for PROCRIT (Epoetin alfa) group patients, for the purpose of real-time dosing decisions. (HemoCue is the brand name of a portable hemoglobin test that uses a drop of blood to obtain immediate hemoglobin measurements). PROCRIT (Epoetin alfa) will be administered at a dose based on the HemoCue Hb measurement. Full hematology panel, serum chemistry, and iron status will be assessed at intervals throughout the study by a central laboratory. The number of units of packed red blood cells (PRBC) transfused, pre-transfusion Hb level, and the reasons for transfusion will be collected. Hemoglobin response will also be measured. A patient exhibiting a hemoglobin response will have two consecutive Hb measurements at least 1 g/dL greater than baseline any time during the study or have two consecutive Hb measurements >= 11.0 g/dL at any time during the study. Falls, activities of daily living (ADLs), and mobility will be assessed during the study. Clinical laboratory results, blood pressure and heart rate, and the incidence and severity of adverse events will be monitored during the study.
The study hypothesis is that the mean Hb change from baseline to the end of study will be significantly higher in the PROCRIT (Epoetin alfa) group over the control group. Group 1 patients will receive a maximum of 13 doses of PROCRIT (Epoetin alfa) by subcutaneous injection (under the skin) for up to 26 weeks. Dosage is based on the hemoglobin measurement done at each visit. Doses will be started at an every 2-week interval and may be increased to every four weeks. The maximum dose that can be given is 60,000 Units of PROCRIT (Epoetin alfa) over a 4-week period. Any PROCRIT (Epoetin alfa) dose over 40,000 Units will be administered in two separate injections.
