Methoxy Polyethylene Glycol-epoetin Beta
Generic Name: methoxy polyethylene glycol-epoetin beta
Brand Names:
Mircera
11 DESCRIPTION Methoxy polyethylene glycol-epoetin beta, is an ESA which differs from erythropoietin through formation of a chemical bond between either the N-terminal amino group or the ε-amino group of any lysine present in erythropoietin, predominantly Lys 52 and Lys 45 , and methoxy polyethylene glycol (PEG) butanoic acid (approximately 30,000 daltons). This results in a total molecular weight of approximately 60,000 daltons.

Uses
1 INDICATIONS AND USAGE Mircera is an erythropoiesis-stimulating agent (ESA) indicated for the treatment of anemia associated with chronic kidney disease (CKD) in: • adult patients on dialysis and adult patients not on dialysis ( 1.1 ). • pediatric patients 3 months to 17 years of age on dialysis or not on dialysis who are converting from another ESA after their hemoglobin level was stabilized with an ESA ( 1.1 ). Limitations of Use Mircera is not indicated and is not recommended for use: • In the treatment of anemia due to cancer chemotherapy ( 5.2 ). • As a substitute for RBC transfusions in patients who require immediate correction of anemia ( 12.2 ). Mircera has not been shown to improve quality of life, fatigue, or patient well-being.
Dosage
2 DOSAGE AND ADMINISTRATION Mircera is administered by subcutaneous or intravenous injection ( 2.2 ). Adult Patients • Initial Treatment: (patients not currently treated with an ESA): • CKD patients on dialysis: 0.6 mcg/kg body weight administered once every two weeks ( 2.2 ). • CKD patients not on dialysis: 1.2 mcg/kg body weight administered once every month as a single subcutaneous injection. Alternatively, a starting dose of 0.6 mcg/kg body weight may be administered once every two weeks as a single intravenous or subcutaneous injection ( 2.2 ). • 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 ).
Side Effects
6 ADVERSE REACTIONS The following serious adverse reactions are discussed in greater detail in other sections of the labeling: • Increased Mortality, Myocardial Infarction, Stroke, and Thromboembolism [see Warnings and Precautions ( 5.1 )] • Increased Mortality and/or Tumor Progression in Patients with Cancer [see Warnings and Precautions ( 5.2 )] • Hypertension [see Warnings and Precautions ( 5.3 )] • Seizures [see Warnings and Precautions ( 5.4 )] • Pure Red Cell Aplasia [see Warnings and Precautions ( 5.6 )] • Serious Allergic Reactions [see Warnings and Precautions ( 5.7 )] • Severe Cutaneous Reactions [see Warnings and Precautions ( 5.8 )] The most common adverse reactions (≥ 10%) are hypertension, diarrhea, nasopharyngitis ( 6 ).

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 Mircera treatment, withhold Mircera and evaluate for PRCA ( 5.6 ). • Serious Allergic Reactions: Discontinue Mircera and manage reactions ( 5.7 ). • Severe Cutaneous Reactions: Discontinue Mircera ( 5.8 ). 4 CONTRAINDICATIONS Mircera is contraindicated in patients with: • Uncontrolled hypertension [see Warnings and Precautions ( 5.3 )] • Pure red cell aplasia (PRCA) that begins after treatment with Mircera or other erythropoietin protein drugs [see Warnings and Precautions ( 5.6 )] • History of serious or severe allergic reactions to Mircera (e.g., anaphylactic reactions, angioedema, bronchospasm, s...
Pregnancy
8.1 Pregnancy Risk Summary Available data from a small number of published case reports and postmarketing experience with Mircera use in pregnancy are insufficient to identify a drug associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Chronic kidney disease is associated with maternal and embryo-fetal risks (see Clinical Considerations) .
Storage
16.2 Storage Store Mircera refrigerated at 2°C to 8°C (36°F to 46°F) in the original carton to protect from light. Do not freeze or shake. The end-user may store the product at room temperature up to 25°C (77°F) in the original carton up to 30 days. Discard after 30 days.
