If a severe hypersensitivity reaction occurs, discontinue NEXVIAZYME immediately and initiate appropriate medical treatment. (5.1) Infusion-Associated Reactions (IARs) If severe IARs occur, consider immediate discontinuation and initiation of appropriate medical treatment. (5.2) Risk of Acute Cardiorespiratory Failure in Susceptible Patients Patients susceptible to fluid volume overload, or those with acute underlying respiratory illness or compromised cardiac or respiratory function, may be at risk of serious exacerbation of their cardiac or respiratory status during NEXVIAZYME infusion. (5.3) Hypersensitivity Reactions Including Anaphylaxis Patients treated with NEXVIAZYME have experienced life-threatening hypersensitivity reactions, including anaphylaxis. Appropriate medical monitoring and support measures, including cardiopulmonary resuscitation equipment, should be readily available during NEXVIAZYME administration. If a severe hypersensitivity reaction (e.g., anaphylaxis) occurs, discontinue NEXVIAZYME immediately and initiate appropriate medical treatment. In patients with severe hypersensitivity reactions, a desensitization procedure to NEXVIAZYME may be considered [see Warnings and Precautions (5.1)]. Infusion-Associated Reactions (IARs) Patients treated with NEXVIAZYME have experienced severe IARs. If severe IARs occur, consider immediate discontinuation of NEXVIAZYME, initiation of appropriate medical treatment, and the benefits and risks of readministering NEXVIAZYME following severe IARs. Patients with an acute underlying illness at the time of NEXVIAZYME infusion may be at greater risk for IARs. Patients with advanced Pompe disease may have compromised cardiac and respiratory function, which may predispose them to a higher risk of severe complications from IARs [see Warnings and Precautions (5.2)]. Risk of Acute Cardiorespiratory Failure in Susceptible Patients Patients susceptible to fluid volume overload, or those with acute underlying respiratory illness or compromised cardiac or respiratory function for whom fluid restriction is indicated may be at risk of serious exacerbation of their cardiac or respiratory status during NEXVIAZYME infusion. More frequent monitoring of vitals should be performed during NEXVIAZYME infusion in such patients [see Warnings and Precautions (5.3)].

(6.1) To report SUSPECTED ADVERSE REACTIONS, contact Genzyme at 1-800-633-1610, option 1 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 trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adverse Reactions from Clinical Trials in the Pompe Disease Population The pooled safety analysis from 4 clinical trials in the Pompe disease population (including Study 1) with a mean exposure of 26 months and up to 85 months of treatment included a total of 141 NEXVIAZYME-treated patients (118 adult and 23 pediatric patients [see Clinical Studies (14.1)]. Adverse reactions were similar across both adult and pediatric populations. Serious adverse reactions reported in 2 or more NEXVIAZYME-treated patients were respiratory distress, chills, and pyrexia. A total of 4 NEXVIAZYME-treated patients in clinical trials permanently discontinued NEXVIAZYME due to adverse reactions, including 3 patients who discontinued the treatment because of a serious adverse reaction. The most frequently reported adverse reactions (>5%) in the pooled safety population were abdominal pain, arthralgia, chills, diarrhea, dizziness, dyspnea, erythema, fatigue, flushing, headache, hypertension, hypotension, myalgia, nausea, pruritus, pyrexia, rash, vomiting, and urticaria. Hypersensitivity reactions were reported in 67 (48%) NEXVIAZYME-treated patients, including 6 (4%) patients who reported severe hypersensitivity reactions. Symptoms of severe hypersensitivity reactions (e.g., anaphylaxis) included chest discomfort, erythema, generalized edema, hypotension, hypoxia, rash, respiratory distress, tongue edema, and urticaria. IARs were reported in 48 (34%) NEXVIAZYME-treated patients. Six (4%) NEXVIAZYME-treated patients reported 13 severe IARs including symptoms of chest discomfort, decreased or increased blood pressure, dysphagia, erythema, generalized edema, hypoxia, nausea, respiratory distress, tongue edema, and urticaria. IARs reported in more than 1 patient included chest discomfort, cyanosis, decreased or increased blood pressure, diarrhea, dizziness, erythema, fatigue, feeling hot or cold, generalized edema, headache, hyperhidrosis, hypoxia, influenza-like illness, nausea, pain, pruritus, pyrexia, rash, respiratory distress, tachycardia, throat irritation, tongue edema, tremor, urticaria, and vomiting.

See the full prescribing information for dosage modifications due to hypersensitivity reactions or IARs. (2.3) Must be reconstituted and diluted prior to use. (2.4) For instructions on storage and administration, see full prescribing information. (2.5, 2.6) 2.1 Recommendations Prior to NEXVIAZYME Treatment Prior to NEXVIAZYME administration, consider pretreating with antihistamines, antipyretics, and/or corticosteroids [see Warnings and Precautions (5.1, 5.2)]. NEXVIAZYME must be reconstituted and diluted prior to use [see Dosage and Administration (2.4)]. Appropriate medical monitoring and support measures, including cardiopulmonary resuscitation equipment, should be readily available during NEXVIAZYME administration. 2.2 Recommended Dosage and Administration NEXVIAZYME is administered as intravenous infusion. For patients weighing: 30 kg or more- the recommended dosage is 20 mg/kg (of actual body weight) every two weeks [see Dosage and Administration (2.6)] Less than 30 kg- the recommended dosage is 40 mg/kg (of actual body weight) every two weeks [see Dosage and Administration (2.6)] The initial recommended infusion rate is 1 mg/kg/hour. Gradually increase the infusion rate every 30 minutes if there are no signs of infusion-associated reactions (IARs) [see Dosage and Administration (2.6)]. If one or more doses are missed, restart NEXVIAZYME treatment as soon as possible, maintaining the 2 week interval between infusions thereafter. 2.3 Administration Modifications Due to Hypersensitivity Reactions and/or Infusion-Associated Reactions In the event of a severe hypersensitivity reaction (e.g., anaphylaxis) or severe infusion-associated reaction (IAR), immediately discontinue NEXVIAZYME administration and initiate appropriate medical treatment. For additional recommendations in the event of a severe hypersensitivity reaction or IAR, [see Warnings and Precautions (5.1, 5.2)]. In the event of a mild to moderate hypersensitivity reaction or a mild to moderate IAR, consider temporarily holding the infusion for 30 minutes or slowing the infusion rate by 50% [see Dosage and Administration (2.6)] and initiating appropriate medical treatment [see Warnings and Precautions (5.1, 5.2)]. If symptoms persist for longer than 30 minutes despite holding or slowing the infusion, stop the infusion and monitor the patient. Consider re-initiating the infusion on the same day when symptoms subside at 50% of the rate at which the reaction occurred with appropriate pretreatment. If symptoms subside after holding the infusion, resume infusion at 50% of the rate at which the reaction occurred, and subsequently increase the infusion rate every 15 to 30 minutes by 50% as tolerated.

Avalglucosidase alfa-ngpt 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 case reports of NEXVIAZYME use in pregnant women are insufficient to evaluate for a drug associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes.

However, available data from postmarketing reports and published case reports on alglucosidase alfa (another hydrolytic lysosomal glycogen-specific enzyme replacement therapy) use in pregnant women have not identified a drug-associated risk of adverse pregnancy outcomes. The continuation of treatment for Pompe disease during pregnancy should be individualized to the pregnant woman. Untreated Pompe disease may result in worsening disease symptoms in pregnant women (see Clinical Considerations). Embryo-fetal toxicity studies performed in pregnant mice resulted in maternal toxicity related to an immunologic response (including an anaphylactoid response) and embryo-fetal loss at 17 times the human steady-state AUC at the recommended biweekly dose of 20 mg/kg for LOPD patients weighing ≥30 kg or 10 times the human steady-state AUC at the recommended biweekly dose of 40 mg/kg for LOPD patients weighing <30 kg. Avalglucosidase alfa-ngpt did not cross the placenta in mice, therefore, the adverse effects were likely related to the immunologic response in the mothers. Embryo-fetal toxicity studies performed in pregnant rabbits showed no adverse effects on the fetuses at exposure up to 91 times the human steady-state AUC at the recommended biweekly dosage of 20 mg/kg for LOPD patients weighing ≥30 kg or 50 times the human steady-state AUC at the recommended biweekly dose of 40 mg/kg for LOPD patients weighing <30 kg (see Data). The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, miscarriage, or other adverse outcomes. In the U.S. general population, the background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Pregnant women exposed to NEXVIAZYME, or their healthcare providers, should report NEXVIAZYME exposure by calling 1-800-633-1610, option 1. Clinical Considerations Disease-associated maternal and/or embryo-fetal risk Untreated Pompe disease has been associated with worsening respiratory and musculoskeletal symptoms in some pregnant women. Data Animal data The majority of reproductive toxicity studies in mice included the pretreatment with diphenhydramine (DPH) to prevent or minimize hypersensitivity reactions. The effects of NEXVIAZYME were evaluated based on comparison with a control group treated with DPH alone. Rabbits tested in reproductive toxicity studies were not pretreated with DPH because hypersensitivity reactions were not observed.
