Indication and Important Safety Information for Elfabrio^® (pegunigalsidase alfa-iwxj) 

Indication 

Elfabrio^® (pegunigalsidase alfa-iwxj) is indicated for the treatment of adults with confirmed Fabry disease. 

Important Safety Information 

Prior to Elfabrio administration, consider pretreating with antihistamines, antipyretics, and/or corticosteroids. Inform patients and caregivers of the signs and symptoms of hypersensitivity reactions and infusion-associated reactions (IARs), and instruct them to seek medical care immediately if such symptoms occur. 

• If a severe hypersensitivity reaction (including anaphylaxis) or severe IAR occurs, immediately discontinue Elfabrio administration and initiate appropriate medical treatment.
• If a mild to moderate hypersensitivity reaction or IAR occurs, consider slowing the infusion rate or temporarily withholding the dose.

In clinical trials, 20 (14%) Elfabrio-treated patients experienced hypersensitivity reactions. Four Elfabrio-treated patients (3%) experienced anaphylaxis reactions that occurred within 5 to 40 minutes of the start of the initial infusion. The signs and symptoms of hypersensitivity reactions and anaphylaxis included headache, nausea, vomiting, throat tightness, facial and oral edema, truncal rash, tachycardia, hypotension, rigors, urticaria, intense pruritus, moderate upper airway obstructions, macroglossia, and mild lip edema. 

In clinical trials, 41 (29%) Elfabrio-treated patients experienced one or more infusion-associated reactions, including hypersensitivity, nausea, chills, pruritus, rash, chest pain, dizziness, vomiting, asthenia, pain, sneezing, dyspnea, nasal congestion, throat irritation, abdominal pain, erythema, diarrhea, burning sensation, neuralgia, headache, paresthesia, tremor, agitation, increased body temperature, flushing, bradycardia, myalgia, hypertension, and hypotension.  

A case of membranoproliferative glomerulonephritis with immune depositions in the kidney was reported during clinical trials. Monitor serum creatinine and urinary protein-to-creatinine ratio. If glomerulonephritis is suspected, discontinue treatment until a diagnostic evaluation can be conducted. 

When switching to Elfabrio from a prior enzyme replacement therapy, the risk of hypersensitivity reactions and infusion-associated reactions may be increased in certain patients with pre-existing anti-drug antibodies (ADAs). Consider monitoring IgG and IgE ADAs and clinical or pharmacodynamic response (eg, plasma lyso-Gb3 levels). 

The most common adverse reactions (≥15%) were infusion-associated reactions, nasopharyngitis, headache, diarrhea, fatigue, nausea, back pain, pain in extremity, and sinusitis. 

Please see Full Prescribing Information for Elfabrio.

Indication and Important Safety Information for Lamzede^® (velmanase alfa-tycv) 

Indication

Lamzede^® (velmanase alfa-tycv) is indicated for the treatment of non-central nervous system manifestations of alpha-mannosidosis in adult and pediatric patients. 

Important Safety Information 

 
Considerations Due to Hypersensitivity Reactions and/or Infusion-Associated Reactions (IARs) 

Prior to Lamzede administration, consider pretreating with antihistamines, antipyretics, and/or corticosteroids. Inform patients and caregivers of the signs and symptoms of hypersensitivity reactions and IARs and instruct them to seek medical care immediately if such symptoms occur.

• If a severe hypersensitivity reaction (including anaphylaxis) or severe IAR occurs, immediately discontinue Lamzede administration and initiate appropriate medical treatment.
• In the event of a mild to moderate hypersensitivity reaction or a mild to moderate IAR, consider temporarily holding the infusion for 15 to 30 minutes, slowing the infusion rate to 25% to 50% of the recommended rate, and initiating appropriate medical treatment. 

Hypersensitivity Reactions Including Anaphylaxis 

Anaphylaxis and severe hypersensitivity signs and symptoms included cyanosis, hypotension, emesis, urticaria, erythema, facial swelling, pyrexia, and tremor. 

Infusion-Associated Reactions (IARs) 

The most frequent symptoms of IARs that occurred in >10% of the population were pyrexia, chills, erythema, vomiting, cough, urticaria, rash, and conjunctivitis.  

Females of Reproductive Potential  

Advise females of reproductive potential to use effective contraception during treatment and for 14 days after the last dose if Lamzede is discontinued. For females of reproductive potential, verify that the patient is not pregnant prior to initiating treatment with Lamzede. 

Embryo-Fetal Toxicity 

Based on findings from animal reproduction studies, Lamzede may cause embryo-fetal harm when administered to a pregnant female. 

Common Adverse Reactions 

The most common adverse reactions (incidence >20%) are hypersensitivity reactions including anaphylaxis, nasopharyngitis, pyrexia, headache, and arthralgia. 

Please see Full Prescribing Information for Lamzede.
