Cerliponase Alfa
Generic Name: cerliponase alfa
Brand Names:
Brineura
11 DESCRIPTION Cerliponase alfa is a purified human enzyme produced by recombinant DNA technology in a Chinese hamster ovary cell line. The active substance is a recombinant human tripeptidyl peptidase-1 (rhTPP1), a lysosomal exopeptidase. The primary activity of the mature enzyme is the cleavage of N-terminal tripeptides from a broad range of protein substrates. Cerliponase alfa contains 544 amino acids with an average molecular mass of 59 kDa. The mature enzyme is 368 amino acids in length.

Uses
1 INDICATIONS AND USAGE BRINEURA is indicated to slow the loss of ambulation in pediatric patients with neuronal ceroid lipofuscinosis type 2 (CLN2 disease), also known as tripeptidyl peptidase 1 (TPP1) deficiency. BRINEURA is a hydrolytic lysosomal N-terminal tripeptidyl peptidase indicated to slow the loss of ambulation in pediatric patients with neuronal ceroid lipofuscinosis type 2 (CLN2 disease), also known as tripeptidyl peptidase 1 (TPP1) deficiency.

Dosage
2 DOSAGE AND ADMINISTRATION Administration of BRINEURA should be supervised by a healthcare provider knowledgeable in the management of hypersensitivity reactions including anaphylaxis. ( 2.1 ) BRINEURA should be administered by or under the supervision of a physician experienced in intraventricular administration. ( 2.1 ) Premedication of patients with antihistamines with or without antipyretics or corticosteroids is recommended. ( 2.1 ) Prior to each infusion, inspect the scalp for signs of intraventricular access device reservoir leakage, failure, or potential infection. ( 2.1 ) Recommended BRINEURA dosage is 300 mg administered once every other week as an intraventricular infusion. In patients less than 2 years of age, lower doses are recommended.
Side Effects
6 ADVERSE REACTIONS The following adverse reactions are described below and elsewhere in the labeling: Hypersensitivity Reactions Including Anaphylaxis [see Warnings and Precautions (5.1) ] Meningitis and Other Intraventricular Access Device-Related Infections [see Warnings and Precautions (5.2) ] Intraventricular Access Device-Related Complications [see Warnings and Precautions (5.3) ] Cardiovascular Adverse Reactions [see Warnings and Precautions (5.4) ] Infusion-Associated Reactions [see Warnings and Precautions (5.5) ] Most common adverse reactions (≥8%) are: pyrexia, ECG abnormalities, decreased CSF protein, vomiting, seizures, device-related complications, hypersensitivity, increased CSF protein, hematoma, headache, irritability, pleocytosis, device-related infections, bradycardia, f...
Warnings
WARNING: HYPERSENSITIVITY REACTIONS INCLUDING ANAPHYLAXIS Patients treated with enzyme replacement therapies have experienced life-threatening hypersensitivity reactions, including anaphylaxis. Anaphylaxis has occurred during the early course of enzyme replacement therapy and after extended duration of therapy. Initiate BRINEURA in a healthcare setting with appropriate medical monitoring and support measures, including access to cardiopulmonary resuscitation equipment. 5 WARNINGS AND PRECAUTIONS Meningitis and Other Intraventricular Access Device-Related Infections : Monitor the device insertion site for signs of infection. ( 4 , 5.2 ) Intraventricular Access Device-Related Complications : Consult a neurosurgeon for any complications with the implanted device. In case of device-related complication, discontinue the infusion and refer to the device labeling for further instructions. ( 4 , 5.3 ) Cardiovascular Adverse Reactions : Monitor vital signs before, during, and post-infusion. Monitor Electrocardiogram (ECG) in patients with a history of bradycardia, conduction disorder, or with structural heart disease, during the infusion. In patients without cardiac abnormalities, perform regular 12-lead ECG evaluations every 6 months. 4 CONTRAINDICATIONS BRINEURA is contraindicated in patients with: any sign or symptom of acute, unresolved localized infection on or around the device insertion site (e.g., cellulitis or abscess); or suspected or confirmed CNS infection (e.g., cloudy CSF or positive CSF gram stain, or meningitis) [see Warnings and Precautions (5.2) ] .
Pregnancy
8.1 Pregnancy Risk Summary There are no available data on BRINEURA use in pregnant women to inform a drug-associated risk of pregnancy-related outcomes. Animal reproduction studies have not been conducted using cerliponase alfa. 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.
