⏳ 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.

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying and controlled conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Atopic Dermatitis The safety of EBGLYSS was evaluated across 4 randomized, double-blind, placebo-controlled, multicenter trials in subjects with moderate-to-severe atopic dermatitis including 3 phase 3 trials (ADvocate 1, ADvocate 2, ADhere) and 1 phase 2 dose ranging trial (KGAF).
In these 4 trials, mean age was 37 years; 50% of subjects were male; 62% were White, 13% were Black, and 20% were Asian. In terms of co-morbid conditions, in the phase 3 trials, 30% of the subjects had asthma, 50% had allergic rhinitis, 31% had food allergy, and 14% had allergic conjunctivitis at baseline. A total of 891 subjects were treated with EBGLYSS for at least 1 year in the atopic dermatitis development program.
ADvocate 1, ADvocate 2, and KGAF compared the safety of EBGLYSS monotherapy to placebo. ADhere compared the safety of EBGLYSS + TCS to placebo + TCS through 16 weeks. All subjects from the phase 3 trials were allowed to enroll in the long-term extension study.
Weeks 0 to 16 Table 1 summarizes the adverse reactions that occurred at a rate of at least 1% in the EBGLYSS 250 mg every 2 weeks monotherapy group, or in the EBGLYSS 250 mg every 2 weeks + TCS group, all at a higher rate than placebo during the first 16 weeks of treatment.

In the TCS trial (ADhere) through Week 16, the proportion of subjects who discontinued treatment due to adverse events was 2.1% in the EBGLYSS 250 mg every 2 weeks + TCS group and 0% in the placebo + TCS group. The most common adverse reactions leading to discontinuation of EBGLYSS compared to the placebo group were conjunctivitis and keratitis (0.6% vs. 0.3%), and injection site reactions (0.2% vs.
0) in the monotherapy trials; and conjunctivitis (0.7% vs. 0), and injection site reactions (0.7% vs. 0) in the TCS trial.
Eosinophilia Increased post-baseline blood eosinophils were observed at a higher frequency in EBGLYSS-treated subjects compared to placebo. During the first 16 weeks, eosinophilia (>5000 cells/mcL) was observed in 0.4% in the EBGLYSS-treated subjects and 0% in subjects receiving pla…

Monoclonal antibodies are actively transported across the placenta (see Clinical Considerations) . In animal reproduction studies, no effects on embryo-fetal development were observed after subcutaneous administration of lebrikizumab-lbkz to cynomolgus monkeys during organogenesis at doses up to 18 times the human exposure at the maximum recommended human dose (MRHD) (see Data) .
All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. 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.
Report pregnancies to Eli Lilly and Company at 1-800-LillyRx (1-800-545-5979). Clinical Considerations Fetal/Neonatal Adverse Reactions Transport of endogenous IgG antibodies across the placenta increases as pregnancy progresses and peaks during the third trimester. Therefore, EBGLYSS may be present in infants exposed in utero.
The potential clinical impact of EBGLYSS exposure in infants exposed in utero should be considered. Data Animal Data In an embryofetal development study, no malformations or embryofetal toxicity were observed in fetuses from pregnant cynomolgus monkeys administered lebrikizumab-lbkz during organogenesis at doses up to 150 mg/kg initial dose followed by 50 mg/kg per week by subcutaneous injection, which was associated with plasma exposure (C avg,ss ) approximately 18 times the human exposure at the MRHD. Lebrikizumab-lbkz crossed the placenta in monkeys.
In a prenatal and postnatal development study, pregnant cynomolgus monkeys were administered lebrikizumab-lbkz during organogenesis to parturition at doses up to 150 mg/kg initial dose followed by 50 mg/kg per week by subcutaneous injection, which was associated with plasma exposure (C avg,ss ) approximately 18 times the human exposure at the MRHD. No embryofetal toxicity or malformations, or effects on morphological, functional, or immunological development were observed in the infants from birth through 6 months of age.
8.2Lactation Risk Summary There are no data on the presence of lebrikizumab-lbkz in human milk, the effects on the breastfed infant, or the effects on milk production. Endogenous IgG and monoclonal antibodies are transferred in human milk. The effects of local gastrointestinal exposure and limited systemic exposure in the breastfed infant to lebrikizumab-lbkz are unknown.
The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for EBGLYSS and any potential adverse effects on the breastfed infant from EBGLYSS or from the underlying maternal condition.
8.4Pediatric Use The safety and effectiveness of EBGLYSS have been established in pediatric patients 12 years of age and older who weigh at least 40 kg with moderate-to-severe atopic dermatitis whose disease is not adequately controlled with topical prescription therapies or when those therapies are not advisable.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Lebrikizumab-lbkz is an IgG4 monoclonal antibody that binds with high affinity and slow off-rate to interleukin (IL)-13 and allows IL-13 to bind to IL-13Rα1 but inhibits human IL-13 signaling through the IL-4Rα/IL-13Rα1 receptor complex. IL-13 is a naturally occurring cytokine that is involved in Type 2 inflammation, which is an important component in the pathogenesis of atopic dermatitis. Lebrikizumab-lbkz inhibits IL-13-induced responses including the release of proinflammatory cytokines, chemokines and IgE.
Lebrikizumab-lbkz-bound IL-13 can still bind IL-13Rα2 allowing subsequent internalization and natural clearance of IL-13.
12.2Pharmacodynamics In clinical studies, lebrikizumab-lbkz reduced the levels of serum periostin, total immunoglobulin E (IgE), CC chemokine ligand (CCL)17 [thymus and activation-regulated chemokine (TARC)], CCL18 [pulmonary and activation-regulated chemokine (PARC)], and CCL13 [monocyte chemotactic protein-4 (MCP-4)]. The clinical relevance of these biomarkers is not completely understood. The effectiveness of the maintenance dosage of EBGLYSS 250 mg every 8 weeks was established using longitudinal exposure-response modeling.
Longitudinal exposure-response model predictions were consistent for EBGLYSS maintenance dosages of 250 mg every 8 weeks and 250 mg every 4 weeks.
12.3Pharmacokinetics Lebrikizumab-lbkz steady-state exposure following either a subcutaneous dose of 250 mg every 2 weeks, every 4 weeks, or every 8 weeks in patients with atopic dermatitis are presented in Table 2 . Lebrikizumab-lbkz exposure increases dose-proportionally over a subcutaneous dose range of 37.5 to 500 mg. Lebrikizumab-lbkz steady state is achieved at Week 4 following the approved recommended loading doses.
Table 2: Lebrikizumab-lbkz Steady-State Exposure Following Subcutaneous Administration in Patients with Atopic Dermatitis C max = Maximum concentration, C avg = Average concentration, C trough = Trough concentration a Following approved recommended loading doses Lebrikizumab-lbkz Dosage a C max C avg C trough 250 mg every 2 weeks 108 mcg/mL 100 mcg/mL 87 mcg/mL 250 mg every 4 weeks 63 mcg/mL 51 mcg/mL 36 mcg/mL 250 mg every 8 weeks 43 mcg/mL 26 mcg/mL 11 mcg/mL Absorption Following a single subcutaneous 250 mg dose of lebrikizumab-lbkz, peak serum concentrations were achieved approximately 7 to 8 days post dose.
The absolute bioavailability for a subcutaneous dose was approximately 86%. Injection site locations did not influence the absorption of lebrikizumab-lbkz. Distribution The lebrikizumab-lbkz steady-state volume of distribution is
5.14L. Metabolism/Elimination Lebrikizumab-lbkz is expected to be degraded into small peptides and amino acids via catabolic pathways in the same manner as endogenous IgG. The lebrikizumab-lbkz half-life is 24.5 days and clearance is 0.154 L/day.
Lebrikizumab-lbkz exhibits linear elimination that is independent of dose. Specific Populations Age, Sex, Race Age, sex, or race did not have a significant effect on the pharmacokinetics of lebrikizumab-lbkz. Weight Lebrikizumab-lbkz trough concentrations were lower in subjects with higher body weight.
Patients with Renal or Hepatic Impairment Specific clinical pharmacology studies to evaluate the effects of renal impairment and hepatic impairment on the pharmacokinetics of lebrikizumab-lbkz have not been conducted. Lebrikizumab-lbkz, as a monoclonal antibody, is not expected to undergo significant hepatic or renal elimination. No clinically significant differences in the pharmacokinetics of lebrikizumab-lbkz were observed in patients with mild or moderate renal impairment.
Drug Interaction Studies The effect of lebrikizumab-lbkz on the PK of co-administered medications has not been studied.
12.6Immunogenicity The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of…
