🩺 Clinical
Cerliponase alfa is used to slow the loss of being able to crawl or walk in children with neuronal ceroid lipofuscinosis type 2 (CLN2 disease; an inherited disease of the nervous system), also known as tripeptidyl peptidase 1 (TPP1) deficiency. Cerliponase alfa is in a class of medications called enzymes. It works by replacing the lack of TPP1 in the nervous system.

⏳ Availability & biosimilar status
Biologics have no small-molecule generics; biosimilar competition is tracked in the FDA Purple Book.
Why the date isn’t exact: Biosimilar timing can change because patents may be challenged, settled, licensed, added or removed, and litigation can move the real date earlier or later.
🛈 What do these terms mean?
- Biologic patent
- A patent the reference product’s maker has publicly listed. A biosimilar generally can’t launch until these expire — unless they’re invalidated or resolved in a settlement.
- Reference-product exclusivity
- A flat 12 years of FDA market protection from the biologic’s first licensure (the BPCIA). No biosimilar can be licensed before it ends, regardless of patents.
- Interchangeable exclusivity
- The first interchangeable biosimilar can earn a period as the only interchangeable version (pharmacists can substitute it without the prescriber).
- Earliest biosimilar (LOE)
- The latest of all the dates above — the soonest a biosimilar can realistically reach the market. Litigation and settlements can move it earlier.
Biologics have no small-molecule “generics” — competition comes from FDA-licensed biosimilars, tracked in the FDA Purple Book.
| Code | What it grants | Expires |
|---|---|---|
| RefProduct | Reference-product exclusivity (12-year, BPCIA) — no biosimilar can be licensed before this date | Apr 27, 2029 |

5.1Hypersensitivity Reactions Including Anaphylaxis Life-threatening hypersensitivity reactions including anaphylaxis have been reported in patients treated with enzyme replacement therapies, including BRINEURA . BRINEURA-treated patients have had these reactions occur in clinical studies and postmarketing use [see Adverse Reactions (6) ] . In clinical Trial 1 and Trial 2 to 96 weeks, a total of 11 of 24 (46%) patients experienced hypersensitivity reactions during the infusion or within 24 hours of completion of the infusion.
Patients in clinical trials were routinely pre-medicated with antihistamines with or without antipyretics or corticosteroids, prior to infusion of BRINEURA. During postmarketing use, anaphylactic reactions occurred during or within several hours of BRINEURA infusion. Epinephrine was administered in these patients, and they received subsequent BRINEURA infusions without recurrence of anaphylaxis.
In Trial 3, hypersensitivity reactions were reported in 5 of 8 (63 %) patients less than 3 years of age at baseline as compared to 0 of 6 patients ≥ 3 years of age at baseline [see Adverse Reactions (6.1) ] . Of the reported hypersensitivity reactions, a single anaphylactic reaction occurred in a subject < 3 years of age. Anaphylaxis has occurred during the early course of enzyme replacement therapy and after extended duration of therapy.
Administration of BRINEURA should be supervised by a healthcare provider knowledgeable in the management of hypersensitivity reactions including anaphylaxis. Initiate BRINERUA in a healthcare setting with appropriate medical monitoring and support measures, including access to cardiopulmonary resuscitation equipment. Premedication of patients with antihistamines with or without antipyretics or corticosteroids is recommended 30 to 60 minutes prior to the start of infusion.
Observe patients closely during and after the infusion. If a severe hypersensitivity reaction (e.g., anaphylaxis) occurs, discontinue BRINEURA and immediately initiate appropriate medical treatment including use of epinephrine. Inform patients and caregivers of the symptoms of life-threatening hypersensitivity reactions, including anaphylaxis and to seek immediate medical care should symptoms occur.
The management of hypersensitivity reactions should be based on the severity of the reaction and may include temporarily interrupting the infusion, and/or treatment with antihistamines, antipyretics, and/or corticosteroids. Consider the risks and benefits of readministration of BRINEURA following an anaphylactic reaction. If the decision is made to readminister BRINEURA after the occurrence of anaphylaxis, ensure appropriately trained personnel and equipment for emergency resuscitation (including epinephrine and other emergency medicines) are readily available during infusion.
Initiate subsequent infusion at approximately one-half the initial infusion rate at which the anaphylactic reaction occurred.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy 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. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
8.2Lactation Risk Summary There are no data on the presence of cerliponase alfa in human milk, the effects on the breastfed child, or the effects on milk production. The lack of clinical data during lactation precludes a clear determination of the risk of BRINEURA to an infant during lactation; therefore, the development and health benefits of breastfeeding should be considered along with the mother's clinical need for BRINEURA and any potential adverse effects on the breastfed infant from BRINEURA or from the underlying maternal condition.
8.4Pediatric Use The safety and effectiveness of BRINEURA have been established to slow the loss of ambulation in pediatric patients with CLN2 disease and the information on this use is discussed throughout the labeling. BRINEURA is not recommended for use in patients less than 37 weeks post-menstrual age (gestational age at birth plus post-natal age) or those weighing less than 2.5 kg due to physiologic immaturity which may increase risk of serious and clinically significant adverse reactions observed with BRINEURA [see Warnings and Precautions (5) ] .
Patients less than 3 years of age may be at increased risk for developing hypersensitivity reactions with BRINEURA use compared to patients 3 years of age and older [see Warnings and Precautions (5.1) and Adverse Reactions (6.1) ].

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action CLN2 disease is a neurodegenerative disease caused by deficiency of the lysosomal enzyme tripeptidyl peptidase-1 (TPP1), which catabolizes polypeptides in the CNS. TPP1 has no known substrate specificity. Deficiency in TPP1 activity results in the accumulation of lysosomal storage materials normally metabolized by this enzyme in the central nervous system (CNS), leading to progressive decline in motor function.
Cerliponase alfa (rhTTP1), a proenzyme, is taken up by target cells in the CNS and is translocated to the lysosomes through the Cation Independent Mannose-6-Phosphate Receptor (CI-MPR, also known as M6P/IGF2 receptor). Cerliponase alfa is activated in the lysosome and the activated proteolytic form of rhTPP1 cleaves tripeptides from the N-terminus of proteins.
12.2Pharmacodynamics No formal pharmacodynamic studies have been conducted with cerliponase alfa.
12.3Pharmacokinetics Patients 3 years of age and older The pharmacokinetics of cerliponase alfa were evaluated in patients with CLN2 disease who received intraventricular infusions of 30 mg (0.1 times the maximum approved recommended dosage), 100 mg (approximately 0.3 times the maximum approved recommended dosage), and 300 mg over approximately 4.5 hours once every other week. Cerliponase alfa CSF exposure following the initial single dose administration of BRINEURA increased less than proportionally across doses of 30 mg, 100 mg, and 300 mg.
There was no apparent accumulation of cerliponase alfa in CSF or plasma when BRINEURA was administered at a dose of 300 mg once every other week. Cerliponase alfa pharmacokinetics have high inter-subject and intra-subject variability. Following intraventricular infusions of 300 mg of BRINEURA at Day 1, Week 5, and Week 13, the pharmacokinetic parameters in CSF and plasma were assessed in 14 patients and are summarized in Table 4.

Pediatric patients less than 3 years Pediatric CLN2 patients ages 1 to < 2 years (n=2) and 2 to < 3 years (n=6) were administered cerliponase alfa according to the recommended dosing regimen based on age for up to 144 weeks. CSF exposure with 300 mg cerliponase alfa was within the range characterized to be safe and effective in pivotal Trial 1. Plasma exposure in younger patients trended higher than the range characterized in the pivotal study.

📋 Description ▾
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. There are 5 consensus N-glycosylation sites on rhTPP1 that contain high mannose, phosphorylated high mannose and complex glycosylation structures.
BRINEURA (cerliponase alfa) Injection and Intraventricular Electrolytes Injection are administered by intraventricular infusion. The solutions are sterile, nonpyrogenic, and free of foreign particulates. BRINEURA is a clear to slightly opalescent and colorless to pale yellow solution.
Intraventricular Electrolytes is a clear to colorless solution. BRINEURA and Intraventricular Electrolytes Injection are packaged in 10 mL clear Type 1 single-dose glass vials [see How Supplied/Storage and Handling (16) ]. Each vial of BRINEURA provides 5 mL of solution containing 150 mg cerliponase alfa.
Each vial of Intraventricular Electrolytes Injection provides 5 mL of solution. Both BRINEURA and Intraventricular Electrolytes Injection are formulated with the following excipients: calcium chloride dihydrate (1.05 mg); magnesium chloride hexahydrate (0.8 mg); potassium chloride (1.1 mg); sodium chloride (43.85 mg); sodium phosphate, dibasic, heptahydrate (0.55 mg); sodium phosphate, monobasic, monohydrate (0.4 mg); and Water for Injection, USP. The pH of the solution is between 6.2 to 6.8 for BRINEURA, and between 6.0 to 7.0 for Intraventricular Electrolytes Injection.
