DY%--V! Retacrit has been approved as a biosimilar, not as an interchangeable product. What is/was your patient's PRETREATMENT hemoglobin level (g/dL) [prior to use of epoetin (Aranesp, Epogen, Mircera, Procrit, Retacrit)]? In pediatric patients, Mircera is administered by intravenous injection only (2.2). Both drugs are costly: January 2003 prices posted by Medicare put reimbursement rates at $12.69 per 1000 units of Procrit (translating to about $534.32 for the Average Wholesale Price [AWP] for a once-a-week dose of 40,000 units) and $23.69 per 5 micrograms of Aranesp (about $994.98 for the AWP for a 3 mcg/kg dose every other week). GrepMed and the images sourced through this website are NOT a substitute for clinical judgement. Questions regarding this interchange program should be directed to the CCF Department of Pharmacy Drug Information Center (216-444-6456, option #1). IL-11 has also been shown to have non-hematopoietic activities in animals including the regulation of intestinal epithelium growth (enhanced healing of gastrointestinal lesions), the inhibition of adipogenesis, the induction of acute phase protein synthesis, inhibition of pro-inflammatory cytokine production by macrophages, and the stimulation of osteoclastogenesis and neurogenesis. Patient treatments were converted from subcutaneous epoetin alfa to weekly, intravenous darbepoetin alfa at month 0, at a conversion dose of 200 units epoetin alfa to 1 microg darbepoetin. Immediately and permanently discontinue RETACRIT and administer appropriate therapy if a serious allergic or anaphylactic reaction occurs, Blistering and skin exfoliation reactions, including erythema multiforme and Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN), have been reported in patients treated with ESAs (including epoetin alfa) in the postmarketing setting. .

In the event that ARDS occurs, Neulasta should be discontinued and/or withheld until resolution of ARDS and patients should receive appropriate medical management for this condition. During the first several months following initiation of RETACRIT, monitor patients closely for premonitory neurologic symptoms. The site is secure. 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%.

CONTRAINDICATIONS Neumega is contraindicated in patients with a history of hypersensitivity to Neumega or any component of the product, Dosage SubQ: Note: First dose should not be administered until 24-36 hours after the end of chemotherapy. Monitoring Parameters Complete blood count and platelet count should be obtained prior to chemotherapy. The recommended RETACRIT 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. <> 1.2 Patients with Acute Myeloid Leukemia Receiving Induction or Consolidation Chemotherapy ZARXIO is indicated for reducing the time to neutrophil recovery and the duration of fever, following induction or consolidation chemotherapy treatment of patients with acute myeloid leukemia (AML) [see Clinical Studies (14.2)]. Drug class: recombinant human erythropoietins, Aranesp (Darbepoetin Alfa Prefilled Syringes), Anemia Associated with Chronic Renal Failure, If hemoglobin exceeds a level needed to avoid RBC transfusion, If hemoglobin increases by less than 1 g/dL. Dosage adjustment: Goal: Dose should be adjusted to achieve and maintain a target hemoglobin not to exceed 12 g/dL. A local search option of this data can be found here. Discontinue RETACRIT therapy immediately if a severe cutaneous reaction, such as SJS/TEN, is suspected, RETACRIT from multiple-dose vials contains benzyl alcohol and is contraindicated for use in neonates, infants, pregnant women, and lactating women. All orders for epoetin alfa-epbx (RETACRIT) will be converted to darbepoetin alfa using equivalent therapeutic interchange dosing listed in the table below. Rounding doses to the nearest vial size often enhances patient convenience and reduces costs without compromising clinical response. Aranesp is the only long-acting erythropoiesis-stimulating agent (ESA) approved for both once weekly (QW) and once every three weeks (Q3W) dosing 1, 2 Aranesp dosing options of QW or Q3W may allow for synchronization with common myelosuppressive chemotherapy regimens. On May 15, 2018, the Food and Drug Administration approved Retacrit (epoetin alfa-epbx, Hospira Inc., a subsidiary of Pfizer Inc.) as a biosimilar to Epogen/Procrit (epoetin alfa, Amgen Inc.) for the treatment of anemia due to chronic kidney disease (CKD) in patients on dialysis and not on dialysis, use of zidovudine in patients with HIV infection, and the effects of concomitant myelosuppressive chemotherapy. In patients receiving treatment for cancer and whose anemia is not due to CKD. Chronic Kidney Disease: In controlled trials, patients experienced greater risks for death, serious adverse cardiovascular reactions, and stroke when administered erythropoiesis-stimulating agents (ESAs) to target a hemoglobin level of greater than 11 g/dL.

Conversion from Another ESA: dosed once monthly or once every two weeks based on total weekly epoetin alfa or darbepoetin alfa dose at time of conversion (2.2). Dose adjustment: If response is not satisfactory after a sufficient period of evaluation (8 weeks of 3 times/week and 4 weeks of once weekly therapy), the dose may be increased every 4 weeks (or longer) up to 300 units/kg 3 times/week, or when dosed weekly, increased all at once to 60,000 units weekly. x]Y8~w&*qq8g91YJUjUr2$u UuKf"3e&U+Wq&0Y Background: Evaluate other causes of anemia.

Bonafont X, Bock A, Carter D, Brunkhorst R, Carrera F, Iskedjian M, Molemans B, Dehmel B, Robbins S. NDT Plus. Patients on Cancer Chemotherapy Initiate Aranesp 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. Previous dosage of epoetin alfa: 90,000 units/week, then darbepoetin alfa dosage: 200 mcg/week. Neutropenic patients receiving Neulasta who develop fever, lung infiltrates, or respiratory distress should be evaluated for the possibility of ARDS. Conclusion: In patients on hemodialysis receiving ESAs, conversion from epoetin alfa to darbepoetin alfa was associated with an approximate and persistent reduction of 65% of the required dose. In some cases, symptoms recurred with rechallenge, suggesting a causal relationship. This site is intended only for U.S. healthcare professionals. Results: Like Epogen/Procrit, the labeling for Retacrit contains a Boxed Warning to alert health care professionals and patients about an increased risk of death, myocardial infarction, stroke, venous thromboembolism, thrombosis of vascular access, and tumor progression or recurrence.
