(ser LIP oh nase AL fa)
Excipient information presented when available (limited, particularly for generics); consult specific product labeling.
Solution, Intraventric [preservative free]:
Brineura: 150 mg/5 mL (1 ea)
Brand Names: U.S.
- Hydrolytic Lysosomal N-terminal Tripeptidyl Peptidase
Cerliponase alfa is a proenzyme that, once activated, cleaves tripeptides from the N-terminus of proteins. This leads to the breakdown of lysosomal storage materials that otherwise accumulate in patients with late infantile neuronal ceroid lipofuscinosis type 2 (CLN2), leading to progressive decline in motor function.
Intraventricular electrolytes (included in the administration kit) are used to flush the infusion line, port needle, and intraventricular access device in order to fully administer cerliponase alfa and maintain patency of the intraventricular access device.
Pediatric patients ≥3 years: VSS: CSF: Median range: 186 to 245 mL; with repeat dosing, volume was observed to decrease
Degraded via peptide hydrolysis
Time to Peak
Pediatric patients ≥3 years: CSF: Median range: 4.3 to 4.5 hours after start of infusion; Plasma: Median range: 12 to 12.3 hours after start of infusion
CSF: 6.2 to 7.7 hours
Use: Labeled Indications
Neuronal ceroid lipofuscinosis type 2: Delay the loss of ambulation in symptomatic pediatric patients ≥3 years of age with late infantile neuronal ceroid lipofuscinosis type 2 (CLN2)
Acute intraventricular access device-related complications (eg, leakage, device failure, device-related infection); ventriculoperitoneal shunts
Note: Administer the first dose 5 to 7 days after device implantation. Pretreat with antihistamines with or without antipyretics or corticosteroids 30 to 60 minutes prior to start of infusion.
Neuronal ceroid lipofuscinosis type 2: Children ≥3 years and Adolescents: Intraventricular: 300 mg (10 mL) once every other week; following cerliponase alfa infusion, administer 2 mL intraventricular electrolytes (included in administration kit)
Dosing: Renal Impairment
There are no dosage adjustments provided in the manufacturer's labeling.
Dosing: Hepatic Impairment
There are no dosage adjustments provided in the manufacturer's labeling.
Thaw cerliponase alfa and intraventricular electrolyte vials at room temperature for approximately 60 minutes. Do not shake or refreeze vials; do not dilute cerliponase alfa or mix with any other drug. Cerliponase alfa may contain thin translucent fibers or opaque particles. Intraventricular electrolytes may contain particles, which appear during the thawing period but should dissolve when the solution reaches room temperature.
Intraventricular: For intraventricular use only; administer to the intraventricular space by infusion pump via a surgically-implanted reservoir and catheter. Infuse utilizing 0.2 micron inline filter (provided in kit) at a rate of 2.5 mL/hour; following cerliponase alfa dose, administer intraventricular electrolytes (included in administration kit) at the same rate. See prescribing information for details on intraventricular infusion.
Store cerliponase alfa injection and intraventricular electrolytes injection upright in a freezer at -25°C to -15°C (-13°F to 5°F) in original carton and protect from light. Store administration kit in original carton separately from cerliponase alfa. Do not freeze kit. Thaw cerliponase alfa and intraventricular electrolytes vials at room temperature for approximately 60 minutes. Preferably, administer immediately after thawing. May store thawed vials at 2°C to 8°C (36°F to 46°F) for 24 hours. Use product held in labeled syringes immediately. If not used immediately, store in syringes at 2°C to 8°C (36°F to 46°F) and use within 4 hours. Vials are single use only.
There are no known significant interactions.

Concerns related to adverse effects:
• Cardiovascular adverse reactions: Hypotension has been reported up to 8 hours after the completion of cerliponase alfa infusion; monitor vital signs. Use with caution in patients with a history of bradycardia, conduction disorder, or structural heart disease; monitor EKG during infusion.
• Device-related complications: Complications can occur with intraventricular access devices. Device-related infections have been reported with cerliponase alfa and may be subclinical. Administer using aseptic technique to minimize infection. Monitor access point skin integrity and send CSF samples routinely for signs of infection. Management of infection may include antibiotic treatment and device replacement before resumption of therapy. Monitor the device for signs of leakage or device failure. Material degradation of the intraventricular access device reservoir may occur with prolonged use (≥105 perforations), requiring replacement of the device.
• Hypersensitivity reactions: Hypersensitivity reactions, including pyrexia, vomiting, pleocytosis and irritability, have been reported in patients, during and up to 24 hours after completion of cerliponase alfa infusion. Pretreat with antihistamines with or without antipyretics or corticosteroids 30 to 60 minutes prior to start of infusion.
• Appropriate use: Administer cerliponase alfa by FDA-approved infusion pump system via intraventricular implanted catheter access (consult prescribing information for device details); health care providers should be experienced with intraventricular drug administration.
Vital signs (blood pressure, heart rate) prior to start of infusion, periodically during infusion and post-infusion; skin integrity (prior to infusion); routine CSF samples (to detect subclinical device infections); 12-lead EKG every 6 months or during infusion with cardiac abnormalities.
Animal reproduction studies have not been conducted with cerliponase alfa.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience headache. Have patient report immediately to prescriber signs of infection, abnormal heartbeat, tachycardia, bradycardia, severe dizziness, passing out, seizures, irritability, anxiety, or vomiting (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
