Laronidase
Generic Name: laronidase
Brand Names:
Aldurazyme
11 DESCRIPTION ALDURAZYME (laronidase) is a polymorphic variant of the human enzyme α-L-iduronidase that is produced by recombinant DNA technology in a Chinese hamster ovary cell line. α-L-iduronidase (glycosaminoglycan α-L-iduronohydrolase, EC 3.2.1.76) is a lysosomal hydrolase that catalyzes the hydrolysis of terminal α-L-iduronic acid residues of dermatan sulfate and heparan sulfate. Laronidase is a glycoprotein with a molecular weight of approximately 83 kD.

Uses
1 INDICATIONS AND USAGE ALDURAZYME ® is indicated for the treatment of: adult and pediatric patients with Hurler and Hurler-Scheie forms of Mucopolysaccharidosis I (MPS I) and patients with the Scheie form of MPS I who have moderate to severe symptoms. ALDURAZYME is a hydrolytic lysosomal glycosaminoglycan (GAG)-specific enzyme indicated for the treatment of adult and pediatric patients with Hurler and Hurler-Scheie forms of Mucopolysaccharidosis I (MPS I) and for the treatment of patients with the Scheie form of MPS I who have moderate to severe symptoms. ( 1 ) Limitations of Use: The risks and benefits of treating mildly affected patients with the Scheie form have not been established.
Dosage
2 DOSAGE AND ADMINISTRATION For pretreatment recommendations, see Full Prescribing Information. ( 2.1 ) The recommended dosage is 0.58 mg/kg administered once weekly as an intravenous infusion. ( 2.2 ) For dosage and administration modifications due to hypersensitivity reactions or infusion-associated reactions (IARs), see Full Prescribing Information. ( 2.3 ) For instructions on preparation, storage, and administration, see Full Prescribing Information. ( 2.4 , 2.5 , 2.6 ) 2.1 Recommendations Prior to ALDURAZYME Treatment Premedication Prior to ALDURAZYME administration, consider premedicating with antihistamines, with or without antipyretics, 60 minutes before the start of infusion [see Warnings and Precautions (5.1 , 5.4) ].
Side Effects
6 ADVERSE REACTIONS Serious and or clinically significant adverse reactions described elsewhere in labeling include: Hypersensitivity Reactions Including Anaphylaxis [see Warnings and Precautions (5.1) ] Acute Respiratory Complications Associated with Administration [see Warnings and Precautions (5.2) ] Acute Cardiorespiratory Failure [see Warnings and Precautions (5.3) ] Infusion-Associated Reactions [see Warnings and Precautions (5.4) ] Most common adverse reactions (≥10%) in patients: 6 months of age and older are: infusion reactions (pyrexia, chills, blood pressure increased, tachycardia, and oxygen saturation decreased). ( 6.1 ) 6 years and older are: rash, upper respiratory tract infection, injection site reaction, hyperreflexia, paresthesia, flushing, and poor venous access.
Warnings
WARNING: HYPERSENSITIVITY REACTIONS INCLUDING ANAPHYLAXIS, and ACUTE RESPIRATORY COMPLICATIONS ASSOCIATED WITH ADMINISTRATION WARNING: HYPERSENSITIVITY REACTIONS INCLUDING ANAPHYLAXIS, and ACUTE RESPIRATORY COMPLICATIONS ASSOCIATED WITH ADMINISTRATION See full prescribing information for complete boxed warning . Appropriate medical monitoring and support measures, including cardiopulmonary resuscitation equipment, should be readily available. 5 WARNINGS AND PRECAUTIONS Risk of Acute Respiratory Complications: Patients with acute febrile or respiratory illness at the time of ALDURAZYME infusion may be at greater risk for infusion reactions. Consider delaying ALDURAZYME infusion. Sleep apnea is common in MPS I patients. Consider evaluating airway patency prior to initiation of treatment with ALDURAZYME. Appropriate respiratory support should be available during infusion. ( 5.2 ) Risk of Acute Cardiorespiratory Failure: Patients susceptible to fluid overload may be at increased risk for serious exacerbation of their cardiac or respiratory status during infusions. Consider a decreased total infusion volume and infusion rate when administering ALDURAZYME to these patients. 4 CONTRAINDICATIONS None. None. ( 4 )
Pregnancy
8.1 Pregnancy Pregnancy Exposure Registry An MPS I Registry has been established. Pregnant women with MPS I and healthcare providers are encouraged to contact the pregnancy sub-registry by visiting www.registrynxt.com or calling 1-800-745-4447 ext. 15500. Risk Summary Available data from the MPS I Registry pregnancy sub-registry, published case reports, and the global pharmacovigilance database with ALDURAZYME use in more than 30 pregnant women have not identified a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes.
Storage
Refrigerate vials of ALDURAZYME at 2°C to 8°C (36°F to 46°F). Do not freeze or shake. Protect from light. This product contains no preservatives.
