Metoxi-polietilenglicol epoetina beta: lo que dice la advertencia en recuadro

Cita de la advertencia en recuadro (Boxed Warning) de la etiqueta aprobada por la FDA. Se muestra en inglés.

WARNING: ESAs INCREASE THE RISK OF DEATH, MYOCARDIAL INFARCTION, STROKE, VENOUS THROMBOEMBOLISM, THROMBOSIS OF VASCULAR ACCESS and TUMOR PROGRESSION OR RECURRENCE See full prescribing information for complete boxed warning 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 (5.1).

• No trial has identified a hemoglobin target level, ESA dose, or dosing strategy that does not increase these risks (5.1).
• Use the lowest Mircera dose sufficient to reduce the need for red blood cell (RBC) transfusions (5.1). Cancer:
• Mircera is not indicated and is not recommended for the treatment of anemia due to cancer chemotherapy. A dose-ranging study of Mircera was terminated early because of more deaths among patients receiving Mircera than another ESA (5.2).
• ESAs shortened overall survival and/or increased the risk of tumor progression or recurrence in clinical studies in patients with breast, non-small cell lung, head and neck, lymphoid, and cervical cancers (5.2). Chronic Kidney Disease [see Warnings and Precautions (5.1)]

To report SUSPECTED ADVERSE REACTIONS, contact Vifor (International) Inc. at 1-800-576-8295, or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of Mircera cannot be directly compared to rates in the clinical trials of other drugs and may not reflect the rates observed in practice. Adult Patients The data described below reflect exposure to Mircera in 2737 patients, including 1451 exposed for 6 months and 1144 exposed for greater than one year. Mircera was studied primarily in active-controlled studies (n=1789 received Mircera, and n=948 received another ESA) and in long-term follow up studies. The population was 18 to 92 years of age, 58% male, and the percentage of Caucasian, Black (including African Americans), Asian and Hispanic patients were 73%, 20%, 5%, and 9%, respectively. Approximately 85% of the patients were receiving dialysis. Most patients received Mircera using dosing regimens of once every two or four weeks, administered subcutaneously or intravenously. The most commonly reported adverse reactions in ≥10% of patients were hypertension [see Warnings and Precautions (5.3)], diarrhea, and nasopharyngitis. The most common adverse reactions that led to treatment discontinuation in the Mircera clinical studies were: hypertension, coronary artery disease, anemia, concomitant termination of other CKD therapy and septic shock. Some of the adverse reactions reported are typically associated with CKD, or recognized complications of dialysis, and may not necessarily be attributable to Mircera therapy. Adverse reaction rates did not importantly differ between patients receiving Mircera or another ESA. Table 6 summarizes the most frequent adverse reactions (≥5%) in patients treated with Mircera.

Dosis de Metoxi-polietilenglicol epoetina beta

Cita de la sección «Dosage and Administration» (dosis y administración) de la etiqueta aprobada por la FDA. Se muestra en inglés. Su dosis es la que le receta su médico: no la cambie por su cuenta.

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.

Leer más de esta sección

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). Pediatric Patients
• Conversion from another ESA: dosed once every 4 weeks based on total weekly epoetin alfa or darbepoetin alfa dose at time of conversion (2.2).
• In patients less than 6 years of age, maintain the same route of administration as the previous ESA when switching from another ESA to Mircera. 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 Mircera [see Warnings and Precautions (5.9)]. 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. Individualization of Dosing Individualize and use the lowest dose of Mircera sufficient to reduce the need for RBC transfusions [see Warnings and Precautions (5.1)]. 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 for adult patients. No trial has identified a hemoglobin target level, ESA dose, or dosing strategy that does not increase these risks. Physicians and patients should weigh the possible benefits of decreasing transfusions against the increased risks of death and other serious cardiovascular adverse events [see Boxed Warning and Clinical Studies (14)]. 2.2 For Adult Patients with CKD Prefilled syringes are not designed for administration of partial doses. Round doses to the closest dose achievable with the prefilled syringes. 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.

Metoxi-polietilenglicol epoetina beta en el embarazo

Cita de la parte sobre embarazo (Pregnancy) de la etiqueta aprobada por la FDA. Se muestra en inglés. Pregunte a su médico antes de tomar cualquier medicamento si está embarazada o planea estarlo.

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).

Leer más de esta sección

In animal reproduction studies, administration of methoxy polyethylene glycol-epoetin beta to rats and rabbits during pregnancy and lactation adversely affected offspring at doses 17-fold and greater than the recommended human dose (see Data). The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Disease Associated Maternal and/or Embryo-Fetal Risk Pregnancy in women with chronic kidney disease has been associated with adverse outcomes including hypertension, pre-eclampsia, miscarriage, premature birth, low-birth-weight, polyhydramnios, and intrauterine growth restriction. Data When methoxy polyethylene glycol-epoetin beta was administered subcutaneously to rats and rabbits during gestation (including the period of organogenesis), bone malformation was observed in both species at 50 mcg/kg once every three days (corresponding to 500 mcg/kg/month or 417-fold the recommended human dose) in studies of embryo-fetal development. This effect was observed as missing caudal vertebrae resulting in a thread-like tail in one rat fetus, absent first digit metacarpal and phalanx on each forelimb resulting in absent pollex in one rabbit fetus, and fused fourth and fifth cervical vertebrae centra in another rabbit fetus. Dose-related reduction in fetal weights was observed in both rats and rabbits. At doses 5 mcg/kg once every three days and higher, corresponding to 50 mcg/kg/month or 42-fold the recommended human dose, methoxy polyethylene glycol-epoetin beta caused exaggerated pharmacodynamic effects in dams. Once-weekly doses of methoxy polyethylene glycol-epoetin beta up to 50 mcg/kg/dose (corresponding to 200 mcg/kg/month or 167-fold the recommended human dose) given to pregnant and lactating rats did not adversely affect pregnancy parameters, natural delivery or litter observations in a study of pre-and postnatal development. Increased deaths and significant reduction in the growth rate of the F1 generation were observed during lactation and early post weaning period at 20 and 50 mcg/kg/dose, corresponding to 80 and 200 mcg/kg/month or 67- and 167-fold the recommended human dose. A significant reduction in the growth rate of the F1 generation was evident already at 5 mcg/kg/dose, corresponding to 20 mcg/kg/month or 17-fold the recommended human dose. However, no remarkable effect on reflex, physical and cognitive development or reproductive performance was observed in F1 generation of any dose groups.
