Brineura (cerliponase alfa) is the only treatment that directly addresses the cause of CLN2 disease by helping to replace the TPP1 enzyme
What is Brineura?

Brineura (cerliponase alfa) is a prescription medication used to slow loss of ability to walk or crawl (ambulation) in symptomatic pediatric patients 3 years of age and older with late infantile neuronal ceroid lipofuscinosis type 2 (CLN2), also known as tripeptidyl peptidase 1 (TPP1) deficiency.

CLN2 disease is a type of lysosomal storage disorder that affects cells in the brain. Lysosomes are in every cell and contain enzymes that break down materials in the cell. One of these enzymes is called TPP1, which is missing or not working properly in children with CLN2 disease.1

How is Brineura administered to my child?
Brineura is a type of treatment called enzyme replacement therapy (ERT). It’s administered through intraventricular infusion a method that allows Brineura to be directly delivered into the fluid surrounding the brain, known as the cerebrospinal fluid.4

Before starting Brineura, your child will need to have an intraventricular access device surgically implanted just below their scalp.4 This is an established procedure in pediatric neurology,5 and allows direct delivery of Brineura into a ventricle in the brain. The access device is about the size of a penny. It’s recommended that the first dose of Brineura treatment begin at least 5 to 7 days after the access device is implanted.4

Brineura treatments will take about 4.5 hours every other week.4 You’ll work with your healthcare team to schedule treatments.

Your healthcare team will let you know how to prepare your child for infusion, and what to expect during this procedure. Your child will be monitored before, during, and after the infusion, and may receive medications to reduce the risk of hypersensitivity reactions.

Your doctor may also take the steps to minimize the risk of device-related infections at every treatment. You may be asked to wear a mask and the number of people in the room will be limited. Ask your team who and what is allowed in the room.

If you see signs of infection, such as swelling or reddening of the skin, contact your healthcare team immediately.

Matty’s infusion day

Matty is a patient with CLN2 disease.
He’s been on treatment with Brineura since 2015.

“After the first few infusions we became more comfortable. The initial surgery for the port was scary, so we felt like that was the first hurdle to jump. Once Matty had a few infusions, we became more comfortable with the process.”

Indication
Brineura® (cerliponase alfa) injection for intraventricular use is indicated to slow the loss of ambulation in symptomatic pediatric patients 3 years of age and older with late infantile neuronal ceroid lipofuscinosis type 2 (CLN2), also known as tripeptidyl peptidase 1 (TPP1) deficiency.
Important Safety Information
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)
  • any acute intraventricular access device-related complications (e.g., leakage, extravasation of fluid, or device failure)
  • ventriculoperitoneal shunts
Important Preparation and Administration Information
Brineura must only be administered via the intraventricular route using aseptic technique to reduce the risk of infection. Administer Brineura and the Intraventricular Electrolytes using the provided Administration Kit for use with Brineura components. Prior to each infusion, inspect the scalp for signs of intraventricular access device leakage or failure and for potential infection. Prior to each infusion of Brineura and when clinically indicated, send cerebrospinal fluid (CSF) samples for testing of cell count and culture.
Special Populations

Brineura has not been studied in pregnancy or lactation.

Safety and effectiveness in pediatric patients below 3 years of age have not been established.

WARNINGS AND PRECAUTIONS
Meningitis and Other Intraventricular Access Device-Related Infections
Bacterial meningitis requiring antibiotic treatment and removal of the device was reported during postmarketing use of Brineura. The signs and symptoms of infections may not be readily apparent in patients with CLN2 disease. To reduce the risk of infectious complications, Brineura should be administered by, or under the direction of, a physician experienced in intraventricular administration.
Intraventricular Access Device-Related Complications
During the clinical trial and in postmarketing reports, intraventricular access device-related complications were reported (e.g., device leakage, device failure, extravasation of CSF fluid, or bulging of the scalp around or above the intraventricular access device). In case of intraventricular access device-related complications, discontinue the Brineura infusion and refer to the device manufacturer’s labeling for further instructions.
Material degradation of the intraventricular access device reservoir was reported after approximately 4 years of administration, which may impact the effective and safe use of the device. The intraventricular access device should be replaced prior to 4 years of single-puncture administrations, which equates to approximately 105 administrations of Brineura.
Cardiovascular Adverse Reactions
Monitor vital signs before infusion starts, periodically during infusion, and post-infusion in a healthcare setting. Perform electrocardiogram (ECG) monitoring during infusion in patients with a history of bradycardia, conduction disorder, or with structural heart disease. In patients without cardiac abnormalities, regular 12-lead ECG evaluations should be performed every 6 months.
Hypersensitivity Reactions, Including Anaphylaxis
Hypersensitivity reactions, including anaphylaxis, have been reported in Brineura-treated patients during clinical studies and postmarketing use. In clinical trials, a total of 11 out of 24 patients (46%) experienced hypersensitivity reactions during the infusion or within 24 hours of completion of the infusion.
Due to the potential for anaphylaxis, appropriate medical support should be readily available when Brineura is administered. If a severe hypersensitivity reaction or anaphylaxis occurs, immediately discontinue the infusion and initiate appropriate medical treatment. Observe patients closely during and after the infusion. Inform patients/caregivers of the signs and symptoms of hypersensitivity reactions and anaphylaxis and instruct them to seek immediate medical care should signs and symptoms occur. Consider the risks and benefits of readministration of Brineura following an anaphylactic reaction.
ADVERSE REACTIONS
In clinical trials, the most frequently reported adverse reactions (≥8%) were pyrexia, ECG abnormalities, decreased CSF protein, vomiting, seizures, device-related complications, hypersensitivity, increased CSF protein, hematoma, headache, irritability, pleocytosis, device-related infection, bradycardia, feeling jittery, and hypotension.
Seizures were reported in 12 of 24 patients and included atonic, generalized tonic-clonic, focal, and absence. Seizures were managed with standard anticonvulsive therapies and did not result in discontinuation of Brineura treatment.
Adverse reactions related to the device were observed in 12 of 24 patients. Device-related adverse reactions include infection, delivery system-related complications, and pleocytosis.
Hematoma adverse reactions were reported in 5 patients and presented as hematoma, post-procedural hematoma, traumatic hematoma, and subdural hematoma. Hematomas did not require treatment and did not interfere with Brineura infusion.
Anti-drug antibodies (ADAs) were detected in serum (79%) and CSF (33%) in patients treated with Brineura. No association was found between serum or CSF ADA titers and incidence or severity of hypersensitivity.

Indication
Brineura® (cerliponase alfa) is a prescription medication used to slow loss of ability to walk or crawl (ambulation) in symptomatic pediatric patients 3 years of age and older with late infantile neuronal ceroid lipofuscinosis type 2 (CLN2), also known as tripeptidyl peptidase 1 (TPP1) deficiency.
Important Safety Information
Brineura is a prescription medicine. Before treatment with Brineura, it is important to discuss your child’s medical history with their doctor. Tell the doctor if they are sick or taking any medication and if they are allergic to any medicines. Your child’s doctor will decide if Brineura is right for them. If you have questions or would like more information about Brineura, contact your child’s doctor.
Brineura is only given by infusion into the fluid of the brain (known as an intraventricular injection) and using sterile technique to reduce the risk of infection. An intraventricular access device or port must be in place at least 5 to 7 days prior to the first infusion. Intraventricular access device-related infections, including meningitis, were observed with Brineura treatment. If any signs of infection or meningitis occur, contact your child’s doctor immediately. The signs and symptoms of infections may not be readily apparent in patients with CLN2 disease. Your doctor should vigilantly be looking for signs and symptoms of infection, including meningitis, during treatment with Brineura.
Your child’s intraventricular access device should be replaced prior to 4 years of single-puncture administration of Brineura, because the device may deteriorate due to repeated use.
Brineura should not be used in patients with active intraventricular access device-related complications (e.g., leakage, device failure, or device-related infection, including meningitis), symptom of acute, unresolved localized infection around the device insertion site (e.g. cellulitis or abscess), or and with shunts used to drain extra fluid around the brain. Your child’s doctor should inspect the scalp and collect samples of your child’s cerebrospinal fluid (CSF) prior to each infusion of Brineura, to check that there is no device failure or infections present.
Low blood pressure and/or slow heart rate may occur during and following the Brineura infusion. Contact your child’s doctor immediately if these reactions occur.
Undesirable or hypersensitivity reactions related to Brineura treatment, including fever, vomiting, and irritability, may occur during treatment and as late as 24 hours after infusion. Your child may receive medication such as antihistamines before Brineura infusions to reduce the risk of reactions. Serious and severe allergic reactions (anaphylaxis) may occur. If a reaction occurs, the infusion will be stopped and your child may be given additional medication. If a severe reaction occurs, the infusion will be stopped and your child will receive appropriate medical treatment. If any signs of anaphylaxis occur, immediately seek medical care.
Safety and effectiveness in pediatric patients below 3 years of age have not been established.
The most common side effects reported during Brineura infusions included fever, problems with the electrical activity of the heart, decreased or increased protein in the fluid of the brain, vomiting, seizures, hypersensitivity, collection of blood outside of blood vessels (hematoma), headache, irritability, and increased white blood cell count in the fluid of the brain, device-related infection, slow heart rate, feeling jittery, and low blood pressure. Intraventricular device-related side effects included infection, delivery system-related complications, and increased white blood cell count in fluid of the brain.
These are not all of the possible side effects with Brineura. Talk to your child’s doctor if they have any symptoms that bother them or that do not go away.
Call your doctor for medical advice about side effects. You may report side effects to BioMarin Pharmaceutical Inc. at 1-866-906-6100, or the FDA at 1-800-FDA-1088 or go to www.fda.gov/medwatch.
