DOSAGE AND ADMINISTRATION Evaluate iron status before and during treatment and maintain iron repletion. Correct or exclude other causes of anemia before initiating treatment ( 2.1 ). In pregnant women, lactating women, neonates, infants: Use only single-dose vials ( 2.1 ). Patients with CKD: Initial dose: 50 to 100 Units/kg 3 times weekly (adults) and 50 Units/kg 3 times weekly (pediatric patients). Individualize maintenance dose. Intravenous route recommended for patients on hemodialysis ( 2.2 ). Patients on Zidovudine due to HIV Infection: 100 Units/kg 3 times weekly ( 2.3 ). Patients with Cancer on Chemotherapy: 40,000 Units weekly or 150 Units/kg 3 times weekly (adults); 600 Units/kg intravenously weekly (pediatric patients ≥ 5 years) ( 2.4 ). Surgery Patients: 300 Units/kg per day daily for 15 days or 600 Units/kg weekly ( 2.5 ). 2.1 Important Dosing Information Evaluation of Iron Stores and Nutritional Factors Evaluate the iron status in all patients before and during treatment. Administer supplemental iron therapy when serum ferritin is less than 100 mcg/L or when serum transferrin saturation is less than 20%. The majority of patients with CKD will require supplemental iron during the course of ESA therapy. Monitoring of Response to Therapy Correct or exclude other causes of anemia (e.g., vitamin deficiency, metabolic or chronic inflammatory conditions, bleeding, etc.) before initiating PROCRIT. Following initiation of therapy and after each dose adjustment, monitor hemoglobin weekly until the hemoglobin level is stable and sufficient to minimize the need for RBC transfusion. Selection of Formulation In pregnant women, lactating women, neonates, and infants use only single-dose vials (the benzyl alcohol-free formulation) [see Contraindications (4) and Use in Specific Populations (8.1 , 8.2 , and 8.4) ]. 2.2 Patients with Chronic Kidney Disease In controlled trials, patients experienced greater risks for death, serious adverse cardiovascular reactions, and stroke when administered ESAs to target a hemoglobin level of greater than 11 g/dL. No trial has identified a hemoglobin target level, ESA dose, or dosing strategy that does not increase these risks. Individualize dosing and use the lowest dose of PROCRIT sufficient to reduce the need for RBC transfusions [see Warnings and Precautions (5.1) ] . Physicians and patients should weigh the possible benefits of decreasing transfusions against the increased risks of death and other serious cardiovascular adverse reactions [see Boxed Warning and Clinical Studies (14) ]. For all patients with CKD: When initiating or adjusting therapy, monitor hemoglobin levels at least weekly until stable, then monitor at least monthly. When adjusting therapy consider hemoglobin rate of rise, rate of decline, ESA responsiveness and hemoglobin variability. A single hemoglobin excursion may not require a dosing change. Do not increase the dose more frequently than once every 4 weeks. Decreases in dose can occur more frequently. Avoid frequent dose adjustments. If the hemoglobin rises rapidly (e.g., more than 1 g/dL in any 2-week period), reduce the dose of PROCRIT by 25% or more as needed to reduce rapid responses. For patients who do not respond adequately, if the hemoglobin has not increased by more than 1 g/dL after 4 weeks of therapy, increase the dose by 25%. For patients who do not respond adequately over a 12-week escalation period, increasing the PROCRIT dose further is unlikely to improve response and may increase risks. Use the lowest dose that will maintain a hemoglobin level sufficient to reduce the need for RBC transfusions. Evaluate other causes of anemia. Discontinue PROCRIT if responsiveness does not improve. For adult patients with CKD on dialysis: Initiate PROCRIT treatment when the hemoglobin level is less than 10 g/dL. If the hemoglobin level approaches or exceeds 11 g/dL, reduce or interrupt the dose of PROCRIT. The recommended starting dose for adult patients is 50 to 100 Units/kg 3 times weekly intravenously or subcutaneously. The intravenous route is recommended for patients on hemodialysis. For adult patients with CKD not on dialysis: Consider initiating PROCRIT treatment only when the hemoglobin level is less than 10 g/dL and the following considerations apply: The rate of hemoglobin decline indicates the likelihood of requiring a RBC transfusion and , Reducing the risk of alloimmunization and/or other RBC transfusion-related risks is a goal If the hemoglobin level exceeds 10 g/dL, reduce or interrupt the dose of PROCRIT, and use the lowest dose of PROCRIT sufficient to reduce the need for RBC transfusions. The recommended starting dose for adult patients is 50 to 100 Units/kg 3 times weekly intravenously or subcutaneously. For pediatric patients with CKD: Initiate PROCRIT treatment only when the hemoglobin level is less than 10 g/dL. If the hemoglobin level approaches or exceeds 12 g/dL, reduce or interrupt the dose of PROCRIT. The recommended starting dose for pediatric patients (ages 1 month or older) is 50 Units/kg 3 times weekly intravenously or subcutaneously. When treating patients who have chronic kidney disease and cancer, physicians should refer to Warnings and Precautions (5.1 and 5.2) . 2.3 Zidovudine-treated Patients with HIV Infection Starting Dose The recommended starting dose in adults is 100 Units/kg as an intravenous or subcutaneous injection 3 times per week. Dose Adjustment If hemoglobin does not increase after 8 weeks of therapy, increase PROCRIT dose by approximately 50 to 100 Units/kg at 4- to 8-week intervals until hemoglobin reaches a level needed to avoid RBC transfusions or 300 Units/kg. Withhold PROCRIT if hemoglobin exceeds 12 g/dL. Resume therapy at a dose 25% below the previous dose when hemoglobin declines to less than 11 g/dL. Discontinue PROCRIT if an increase in hemoglobin is not achieved at a dose of 300 Units/kg for 8 weeks. 2.4 Patients on Cancer Chemotherapy Initiate PROCRIT in patients on cancer chemotherapy only if the hemoglobin is less than 10 g/dL, and if there is a minimum of two additional months of planned chemotherapy. Use the lowest dose of PROCRIT necessary to avoid RBC transfusions. Recommended Starting Dose Adults: 150 Units/kg subcutaneously 3 times per week until completion of a chemotherapy course or 40,000 Units subcutaneously weekly until completion of a chemotherapy course. Pediatric Patients (5 to 18 years): 600 Units/kg intravenously weekly until completion of a chemotherapy course. Dose Reduction Reduce dose by 25% if: Hemoglobin increases greater than 1 g/dL in any 2-week period or Hemoglobin reaches a level needed to avoid RBC transfusion. Withhold dose if hemoglobin exceeds a level needed to avoid RBC transfusion. Reinitiate at a dose 25% below the previous dose when hemoglobin approaches a level where RBC transfusions may be required. Dose Increase After the initial 4 weeks of PROCRIT therapy, if hemoglobin increases by less than 1 g/dL and remains below 10 g/dL, increase dose to: 300 Units/kg three times per week in adults or 60,000 Units weekly in adults 900 Units/kg (maximum 60,000 Units) weekly in pediatric patients After 8 weeks of therapy, if there is no response as measured by hemoglobin levels or if RBC transfusions are still required, discontinue PROCRIT. 2.5 Surgery Patients The recommended PROCRIT regimens are: 300 Units/kg per day subcutaneously for 15 days total: administered daily for 10 days before surgery, on the day of surgery, and for 4 days after surgery. 600 Units/kg subcutaneously in 4 doses administered 21, 14, and 7 days before surgery and on the day of surgery. Deep venous thrombosis prophylaxis is recommended during PROCRIT therapy [see Warnings and Precautions (5.1) ] . 2.6 Preparation and Administration Do not shake. Do not use PROCRIT that has been shaken or frozen. Protect vials from light. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to adminis

WARNINGS AND PRECAUTIONS Increased Mortality, Myocardial Infarction, Stroke, and Thromboembolism: Using ESAs to target a hemoglobin level of greater than 11 g/dL increases the risk of serious adverse cardiovascular reactions and has not been shown to provide additional benefit ( 5.1 and 14.1 ). Use caution in patients with coexistent cardiovascular disease and stroke ( 5.1 ). Increased Mortality and/or Increased Risk of Tumor Progression or Recurrence in Patients with Cancer ( 5.2 ). Hypertension: Control hypertension prior to initiating and during treatment with PROCRIT ( 5.3 ). Seizures: PROCRIT increases the risk for seizures in patients with CKD ( 5.4 ). Increase monitoring of these patients for changes in seizure frequency or premonitory symptoms ( 5.4 ). PRCA: If severe anemia and low reticulocyte count develop during PROCRIT treatment, withhold PROCRIT and evaluate for PRCA ( 5.6 ). Serious Allergic Reactions: Discontinue PROCRIT and manage reactions ( 5.7 ). Severe Cutaneous Reactions: Discontinue PROCRIT ( 5.8 ). 5.1 Increased Mortality, Myocardial Infarction, Stroke, and Thromboembolism In controlled clinical trials of patients with CKD comparing higher hemoglobin targets (13 – 14 g/dL) to lower targets (9 – 11.3 g/dL), PROCRIT and other ESAs increased the risk of death, myocardial infarction, stroke, congestive heart failure, thrombosis of hemodialysis vascular access, and other thromboembolic events in the higher target groups. Using ESAs to target a hemoglobin level of greater than 11 g/dL increases the risk of serious adverse cardiovascular reactions and has not been shown to provide additional benefit [see Clinical Studies (14.1) ] . Use caution in patients with coexistent cardiovascular disease and stroke [see Dosage and Administration (2.2) ] . Patients with CKD and an insufficient hemoglobin response to ESA therapy may be at even greater risk for cardiovascular reactions and mortality than other patients. A rate of hemoglobin rise of greater than 1 g/dL over 2 weeks may contribute to these risks. In controlled clinical trials of patients with cancer, PROCRIT and other ESAs increased the risks for death and serious adverse cardiovascular reactions. These adverse reactions included myocardial infarction and stroke. In controlled clinical trials, ESAs increased the risk of death in patients undergoing coronary artery bypass graft surgery (CABG) and the risk of deep venous thrombosis (DVT) in patients undergoing orthopedic procedures. The design and overall results of the 3 large trials comparing higher and lower hemoglobin targets are shown in Table 1. Table 1: Randomized Controlled Trials Showing Adverse Cardiovascular Outcomes in Patients With CKD Normal Hematocrit Study (NHS) (N=1265) CHOIR (N=1432) TREAT (N=4038) Time Period of Trial 1993 to 1996 2003 to 2006 2004 to 2009 Population CKD patients on hemodialysis with coexisting CHF or CAD, hematocrit 30 ± 3% on epoetin alfa CKD patients not on dialysis with hemoglobin < 11 g/dL not previously administered epoetin alfa CKD patients not on dialysis with type II diabetes, hemoglobin ≤ 11 g/dL Hemoglobin Target; Higher vs. Lower (g/dL) 14.0 vs. 10.0 13.5 vs. 11.3 13.0 vs. ≥ 9.0 Median (Q1, Q3) Achieved Hemoglobin level (g/dL) 12.6 (11.6, 13.3) vs. 10.3 (10.0, 10.7) 13.0 (12.2, 13.4) vs. 11.4 (11.1, 11.6) 12.5 (12.0, 12.8) vs. 10.6 (9.9, 11.3) Primary Endpoint All-cause mortality or non-fatal MI All-cause mortality, MI, hospitalization for CHF, or stroke All-cause mortality, MI, myocardial ischemia, heart failure, and stroke Hazard Ratio or Relative Risk (95% CI) 1.28 (1.06 – 1.56) 1.34 (1.03 – 1.74) 1.05 (0.94 – 1.17) Adverse Outcome for Higher Target Group All-cause mortality All-cause mortality Stroke Hazard Ratio or Relative Risk (95% CI) 1.27 (1.04 – 1.54) 1.48 (0.97 – 2.27) 1.92 (1.38 – 2.68) Patients with Chronic Kidney Disease Normal Hematocrit Study (NHS): A prospective, randomized, open-label study of 1265 patients with chronic kidney disease on dialysis with documented evidence of congestive heart failure or ischemic heart disease was designed to test the hypothesis that a higher target hematocrit (Hct) would result in improved outcomes compared with a lower target Hct. In this study, patients were randomized to epoetin alfa treatment targeted to a maintenance hemoglobin of either 14 ± 1 g/dL or 10 ± 1 g/dL. The trial was terminated early with adverse safety findings of higher mortality in the high hematocrit target group. Higher mortality (35% vs. 29%) was observed for the patients randomized to a target hemoglobin of 14 g/dL than for the patients randomized to a target hemoglobin of 10 g/dL. For all-cause mortality, the HR=1.27; 95% CI (1.04, 1.54); p=0.018. The incidence of nonfatal myocardial infarction, vascular access thrombosis, and other thrombotic events was also higher in the group randomized to a target hemoglobin of 14 g/dL. CHOIR: A randomized, prospective trial, 1432 patients with anemia due to CKD who were not undergoing dialysis and who had not previously received epoetin alfa therapy were randomized to epoetin alfa treatment targeting a maintenance hemoglobin concentration of either 13.5 g/dL or 11.3 g/dL. The trial was terminated early with adverse safety findings. A major cardiovascular event (death, myocardial infarction, stroke, or hospitalization for congestive heart failure) occurred in 125 of the 715 patients (18%) in the higher hemoglobin group compared to 97 of the 717 patients (14%) in the lower hemoglobin group [hazard ratio (HR) 1.34, 95% CI: 1.03, 1.74; p=0.03]. TREAT: A randomized, double-blind, placebo-controlled, prospective trial of 4038 patients with: CKD not on dialysis (eGFR of 20 – 60 mL/min), anemia (hemoglobin levels ≤ 11 g/dL), and type 2 diabetes mellitus, patients were randomized to receive either darbepoetin alfa treatment or a matching placebo. Placebo group patients also received darbepoetin alfa when their hemoglobin levels were below 9 g/dL. The trial objectives were to demonstrate the benefit of darbepoetin alfa treatment of the anemia to a target hemoglobin level of 13 g/dL, when compared to a "placebo" group, by reducing the occurrence of either of two primary endpoints: (1) a composite cardiovascular endpoint of all-cause mortality or a specified cardiovascular event (myocardial ischemia, CHF, MI, and CVA) or (2) a composite renal endpoint of all-cause mortality or progression to end stage renal disease. The overall risks for each of the two primary endpoints (the cardiovascular composite and the renal composite) were not reduced with darbepoetin alfa treatment (see Table 1 ), but the risk of stroke was increased nearly two-fold in the darbepoetin alfa -treated group versus the placebo group: annualized stroke rate 2.1% vs. 1.1%, respectively, HR 1.92; 95% CI: 1.38, 2.68; p < 0.001. The relative risk of stroke was particularly high in patients with a prior stroke: annualized stroke rate 5.2% in the darbepoetin alfa-treated group and 1.9% in the placebo group, HR 3.07; 95% CI: 1.44, 6.54. Also, among darbepoetin alfa-treated subjects with a past history of cancer, there were more deaths due to all causes and more deaths adjudicated as due to cancer, in comparison with the control group. Patients with Cancer An increased incidence of thromboembolic reactions, some serious and life-threatening, occurred in patients with cancer treated with ESAs. In a randomized, placebo-controlled study (Study 2 in Table 2 [see Warnings and Precautions (5.2) ] ) of 939 women with metastatic breast cancer receiving chemotherapy, patients received either weekly epoetin alfa or placebo for up to a year. This study was designed to show that survival was superior when epoetin alfa was administered to prevent anemia (maintain hemoglobin levels between 12 and 14 g/dL or hematocrit between 36% and 42%). This study was terminated prematurely when interim results demonstrated a higher mortality at 4 months (8.7% vs. 3.4%) and a higher rate of fatal thro
