⏳ 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 |
|---|---|---|

Recommended Dosage in Patients 4 Years and Older ( 2.2 ): • Treatment-naïve : 60 units/kg administered every other week as a 60- to 120-minute intravenous infusion. • Patients switching from imiglucerase : Initiate ELELYSO intravenous treatment (60- to 120-minute infusion) with the same units/kg imiglucerase dosage and subsequently administer ELELYSO every other week.
Dosage adjustments can be based on achievement and maintenance of each patient’s therapeutic goals. Preparation and Administration ( 2.3, 2.4, 2.5 ): • Reconstitute, dilute and administer under the supervision of a healthcare professional. • See Full Prescribing Information for complete instructions.
2.1Recommendations Prior to ELELYSO Treatment Administration of ELELYSO should be supervised by a healthcare provider knowledgeable in the management of hypersensitivity reactions including anaphylaxis [see Warnings and Precautions (5.1) ] . Initiate ELELYSO in a healthcare setting with appropriate medical monitoring and support measures, including access to cardiopulmonary resuscitation equipment [see Warnings and Precautions (5.1) ] . To reduce the risk of hypersensitivity reactions, consider pretreatment with antihistamines and/or corticosteroids [see Warnings and Precautions (5.1) ] .
2.2Recommended Dosage in Patients 4 Years and Older Treatment-Naïve Patients 4 Years of Age and Older The recommended dosage of ELELYSO is 60 units/kg (based on actual body weight) administered every other week as a 60- to 120-minute intravenous infusion. Patients 4 Years of Age and Older Switching from Imiglucerase If it is acceptable to switch from a stable imiglucerase dosage to ELELYSO, initiate ELELYSO intravenous treatment (60- to 120-minute infusion) with the same units/kg imiglucerase dosage and subsequently administer ELELYSO every other week.
Dosage adjustments can be made based on achievement and maintenance of each patient's therapeutic goals.
2.3Preparation Instructions ELELYSO should be reconstituted, diluted, and administered under the supervision of a healthcare professional. Prepare ELELYSO according to the following steps using aseptic technique: a. Determine the number of vials to be reconstituted based on the patient's weight in kg and the recommended dose [see Dosage and Administration (2.2) ] .
Round the number of vials up to the next whole number. b. Remove the required number of vials from the refrigerator. Do not leave these vials at room temperature longer than 24 hours prior to reconstitution.
Do not heat or microwave these vials. c. Reconstitute each vial of ELELYSO with 5.1 mL of Sterile Water for Injection, USP to yield a reconstituted product with a concentration of 40 units/mL and an extractable volume of 5 mL. (1) Upon reconstitution, mix vials gently.
DO NOT SHAKE. (2) Prior to further dilution, visually inspect the reconstituted solution in the vials for particulate matter and discoloration. The solution should be clear and colorless.

5 WARNINGS AND PRECAUTIONS See boxed warning ( 5.1 )
5.1Hypersensitivity Reactions Including Anaphylaxis Life‑threatening h ypersensitivity reactions, including anaphylaxis, have occurred in patients treated with enzyme replacement therapies, including ELELYSO . In clinical trials, (patients were not routinely pretreated with antihistamines and/or corticosteroids prior to ELELYSO infusions during the clinical trials): • 2 of 72 (3%) ELELYSO-treated patients experienced signs and symptoms consistent with anaphylaxis including urticaria, hypotension, flushing, wheezing, chest tightness, nausea, vomiting, and dizziness.
These reactions occurred during ELELYSO infusion. • 21 of 72 (29%) ELELYSO-treated patients experienced hypersensitivity reactions, including the 2 ELELYSO‑treated patients who experienced signs and symptoms consistent with anaphylaxis. Signs and symptoms of these hypersensitivity reactions included pruritus, angioedema, flushing, erythema, rash, nausea, vomiting, cough, chest tightness, and throat irritation. These reactions occurred during ELELYSO infusion and up to 3 hours after the start of infusion [see Adverse Reactions (6.1) ] .
Anaphylaxis has occurred during the early course of enzyme replacement therapy and after extended duration of therapy. Administration of ELELYSO should be supervised by a healthcare provider knowledgeable in the management of hypersensitivity reactions including anaphylaxis. Initiate ELELYSO in a healthcare setting with appropriate medical monitoring and support measures, including access to cardiopulmonary resuscitation equipment.
Observe patients closely during and after the infusion. ELELYSO-treated patients who developed anti-taliglucerase alfa antibodies (referred to as anti-drug antibodies (ADA)) generally had a greater frequency of hypersensitivity reactions compared to those who did not develop ADA [see Adverse Reactions (6.1) ] . Closely monitor for hypersensitivity reactions in patients who develop ADA.
Management of hypersensitivity reactions should be based on the severity of the reaction and includes slowing or temporary interruption of the infusion and/or administration of antihistamines, antipyretics, and/or corticosteroids for mild reactions. To reduce the risk of hypersensitivity reactions, consider pretreatment with antihistamines and/or corticosteroids. If a severe hypersensitivity reaction (e.g., anaphylaxis) occurs, discontinue ELELYSO and immediately initiate appropriate medical treatment, including use of epinephrine.
Inform patients of the symptoms of life‑threatening hypersensitivity reactions, including anaphylaxis and to seek immediate medical care should symptoms occur. Consider the risks and benefits of re-administering ELELYSO in patients who have experienced a severe hypersensitivity reaction associated with ELELYSO. Caution should be exercised upon rechallenge [see Adverse Reactions (6.2) ].
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The most common adverse reactions are: • Treatment-Naïve Adults (≥5%): headache, arthralgia, fatigue, nausea, dizziness, abdominal pain, pruritus, flushing, vomiting, urticaria ( 6.1 ). • Patients who Switched from Imiglucerase, after 9 Months on Treatment (≥10%): arthralgia, headache, pain in extremity ( 6.1 ).

The most common adverse reaction (≥10%) was vomiting, which occurred in 4 of 9 patients. Two patients developed hypersensitivity reactions; 1 patient experienced severe vomiting and gastrointestinal inflammation, and 1 experienced mild throat irritation and chest discomfort. Both patients responded to treatment with antihistamines and continued ELELYSO treatment.
Adverse Reactions in a Clinical Trial in Patients Who Switched from Imiglucerase to ELELYSO The safety of ELELYSO was assessed in 31 patients (26 adult and 5 pediatric patients), ages 6 to 66 years old, with Type 1 Gaucher disease who had previously been receiving imiglucerase treatment for a minimum of 2 years (Trial 3). ELELYSO was administered intravenously every other week for 9 months at the same number of units as each patient's previous imiglucerase dose. Table 2 presents the adverse reactions in these ELELYSO-treated patients.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary Available data, including data from a product registry and pharmacovigilance reports, have not identified a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes in pregnant women exposed to ELELYSO. Additionally, there are risks associated with untreated symptomatic Type I Gaucher disease in pregnant women ( see Clinical Considerations ). In animal reproduction studies when pregnant rats and rabbits were administered taliglucerase alfa at intravenous doses up to 5 times the recommended human dose (RHD), there was no evidence of embryo-fetal toxicity ( see Data ).
The background risk of major birth defects and miscarriage for the indicated population is unknown. 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. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Women with Type 1 Gaucher disease have an increased risk of spontaneous abortion if disease symptoms are not treated and controlled pre-conception and during a pregnancy.
Pregnancy may exacerbate existing Type 1 Gaucher disease symptoms or result in new disease manifestations. Type 1 Gaucher disease manifestations may lead to adverse pregnancy outcomes, including hepatosplenomegaly which can interfere with the normal growth of a fetus and thrombocytopenia which can lead to increased bleeding and possible postpartum hemorrhage requiring transfusion. Data Animal Data Reproduction studies have been performed with taliglucerase alfa administered during the period of organogenesis in rats and rabbits.
In rats, intravenous doses up to 55 mg/kg/day (about 5 times the RHD of 60 units/kg based on the body surface area) did not cause any adverse effects on embryo-fetal development. In rabbits, intravenous doses up to 27.8 mg/kg/day (about 5 times the RHD of 60 units/kg based on the body surface area) did not show any embryo-fetal toxicity.
8.2Lactation Risk Summary There are no data on the presence of taliglucerase alfa in human milk or the effects of taliglucerase alfa on milk production. Lactation data from a product registry have not identified adverse reactions in infants exposed to taliglucerase alfa during breastfeeding. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for ELELYSO and any potential adverse effects on the breastfed child from ELELYSO or from the underlying maternal condition.
8.4Pediatric Use The safety and effectiveness of ELELYSO for the treatment of pediatric patients 4 years of age and older with a confirmed diagnosis of Type 1 Gaucher disease has been established. The use of ELELYSO for this indication is supported by evidence of effectiveness from adequate and well-controlled trials of ELELYSO in adults, with additional pharmacodynamic data from 5 pediatric patients and pharmacokinetic data from 9 pediatric patients who participated in clinical trials [see Clinical Studies (14.1 , 14.2) and Clinical Pharmacology (12.3) ].
Data from 14 pediatric patients were included in the safety evaluation [see Adverse Reactions (6.1) ]. The safety and effectiveness of ELELYSO has not been established in patients less than 4 years of age. Pediatric patients experienced a higher frequency of vomiting during ELELYSO treatment (4 of 9 treatment-naïve patients) than adult patients, and this may be a symptom of hypersensitivity reaction.
The frequencies of other adverse reactions were similar between pediatric and adult patients treated with ELELYSO [see Adverse Reactions (6.1) ] .
8.5Geriatric Use During clinical trials, 8 patients aged 65 or older were treated with ELELYSO. Clinical trials of ELELYSO did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Gaucher disease is an autosomal recessive disorder caused by mutations in the human glucocerebrosidase gene, which results in a reduced activity of the lysosomal enzyme glucocerebrosidase. Glucocerebrosidase catalyzes the conversion of the sphingolipid glucocerebroside into glucose and ceramide. The enzymatic deficiency results in accumulation of substrate glucocerebroside primarily in the lysosomal compartment of macrophages, giving rise to foam cells or "Gaucher cells," which accumulate in the liver, spleen and bone marrow.
ELELYSO, an enzyme replacement therapy, is a recombinant analog of human lysosomal glucocerebrosidase that catalyzes the hydrolysis of glucocerebroside to glucose and ceramide, reducing the amount of accumulated glucocerebroside. ELELYSO uptake into cellular lysosomes is mediated by binding of ELELYSO mannose oligosaccharide chains to specific mannose receptors on the cell surface leading to internalization and subsequent transport to the lysosomes.
12.3Pharmacokinetics Pharmacokinetics of taliglucerase alfa were evaluated in 38 patients (29 adult and 9 pediatric patients) who received intravenous infusions of ELELYSO 30 units/kg (50% of the recommended dosage) or 60 units/kg (the recommended dosage) [see Dosage and Administration (2.1) ] every other week. The pharmacokinetic parameters in adult and pediatric patients are summarized in Table 3. In adult Type 1 Gaucher disease patients treated with ELELYSO 30 units/kg (50% of the recommended dosage) or 60 units/kg (the recommended dosage) [see Dosage and Administration (2.1) ] (N=29) every other week as initial therapy, pharmacokinetics were determined with the first dose and at Week 38 of treatment.
The pharmacokinetics of taliglucerase alfa appeared to be nonlinear with a greater than dose-proportional increase in exposure at the doses studied. No significant accumulation or change in taliglucerase alfa pharmacokinetics over time from Weeks 1 to 38 was observed with repeated dosages of 30 units/kg (50% of the recommended dosage) or 60 units/kg (the recommended dosage) [see Dosage and Administration (2.1) ] every other week. Based on the limited data, there were no significant pharmacokinetic differences between male and female patients in this study.
The pharmacokinetics of taliglucerase alfa were evaluated in 9 pediatric patients 4 to 17 years of age with Type 1 Gaucher disease who were treated with ELELYSO for 10 to 27 months. Six of the 9 patients were treatment-naïve, and 3 patients were switched from imiglucerase. In both the 30 units/kg (50% of the recommended dosage) and 60 units/kg (the recommended dosage) [see Dosage and Administration (2.1) ] dose groups, clearance values in pediatric patients were similar to those in adult patients.
AUC values in pediatric patients were lower than AUC values in adult patients, due to weight-based dosing of taliglucerase alfa and lower body weights in pediatric patients.

📋 Description ▾
11 DESCRIPTION Taliglucerase alfa is a hydrolytic lysosomal glucocerebroside-specific enzyme produced by recombinant DNA technology using plant cell culture (carrot). Taliglucerase alfa is a monomeric glycoprotein enzyme containing 4 N-linked glycosylation sites (kDa=60.8). Taliglucerase alfa differs from native human glucocerebrosidase by 2 amino acids at the N terminal and up to 7 amino acids at the C terminal.
Taliglucerase alfa is a glycosylated protein with oligosaccharide chains at the glycosylation sites having terminal mannose sugars. These mannose-terminated oligosaccharide chains of taliglucerase alfa are specifically recognized by endocytic carbohydrate receptors on macrophages, the cells that accumulate lipid in Gaucher disease. A unit is the amount of enzyme that catalyzes the hydrolysis of 1 micromole of the synthetic substrate para-nitrophenyl-β-D-glucopyranoside ( p NP-Glc) per minute at 37 °C.
ELELYSO (taliglucerase alfa) for injection is supplied as a sterile, preservative-free, lyophilized powder for reconstitution and dilution prior to intravenous infusion. Each single-dose vial contains 200 units of taliglucerase alfa and D-mannitol (206.7 mg), polysorbate 80 (0.56 mg), and sodium citrate (30.4 mg). Citric acid may be added to adjust the pH at the time of manufacture.
After reconstitution with 5.1 mL Sterile Water for Injection, USP, taliglucerase alfa concentration is 40 units/mL [see Dosage and Administration (2) ] . Reconstituted solutions have a pH of approximately 6.0.
