⏳ 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.

📄 Full prescribing information FDA SPL
🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE ILUMYA ® is indicated for the treatment of moderate-to-severe plaque psoriasis in aduts who are candidates for systemic therapy or phototherapy. ILUMYA is an interleukin-23 antagonist indicated for the treatment of moderate-to-severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy. ( 1 )
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION See the full prescribing information for recommended evaluations and immunizations prior to treatment. ( 2.1 ) Administer by subcutaneous injection. ( 2.2 ) Recommended dosage is 100 mg at Weeks 0, 4, and every 12 weeks thereafter. ( 2.2 )
2.1Recommended Evaluation and Immunization Prior to Treatment Initiation Evaluate patients for tuberculosis (TB) infection prior to initiating treatment with ILUMYA [see Warnings and Precautions ( 5.3 )] . Consider completion of all age appropriate immunizations according to current immunization guidelines. [see Warnings and Precautions ( 5.4 )]
2.2Dosage ILUMYA is administered by subcutaneous injection. The recommended dosage is 100 mg at Weeks 0, 4, and every 12 weeks thereafter. Each syringe contains 1 mL of 100 mg/mL tildrakizumab-asmn.
2.3Important Administration Instructions ILUMYA should only be administered by a healthcare provider. Administer ILUMYA subcutaneously. Each prefilled syringe is for single-dose only. Inject the full amount (1 mL), which provides 100 mg of tildrakizumab per syringe. If a dose is missed, administer the dose as soon as possible. Thereafter, resume dosing at the regularly scheduled interval.
2.4Preparation and Administration of ILUMYA Before injection, remove ILUMYA carton from the refrigerator, and let the prefilled syringe (in the ILUMYA carton with the lid closed) sit at room temperature for 30 minutes. Follow the instructions on the ILUMYA carton to remove the prefilled syringe correctly, and remove only when ready to inject. Do not pull off the needle cover until you are ready to inject.
Inspect ILUMYA visually for particulate matter and discoloration prior to administration. ILUMYA is a clear to slightly opalescent, colorless to slightly yellow solution. Do not use if the liquid contains visible particles or the syringe is damaged.
Air bubbles may be present; there is no need to remove them. Choose an injection site with clear skin and easy access (such as abdomen, thighs, or upper arm). Do not administer 2 inches around the navel or where the skin is tender, bruised, erythematous, indurated, or affected by psoriasis.
Also, do not inject into scars, stretch marks, or blood vessels. While holding the body of the syringe, pull the needle cover straight off (do not twist) and discard. Inject ILUMYA subcutaneously as recommended [see Dosage and Administration (2.3) ] .
Press down the blue plunger until it can go no further. This activates the safety mechanism that will ensure full retraction of the needle after the injection is given. Remove the needle from the skin entirely before letting go of the blue plunger.
After the blue plunger is released, the safety lock will draw the needle inside the needle guard. Discard any unused portion. Dispose of used syringe. image-1 image-2 image-3
💊 Dosage Forms and Strengths ▾
3 DOSAGE FORMS AND STRENGTHS Injection: 100 mg/mL solution in a single-dose prefilled syringe. ILUMYA is a clear to slightly opalescent, colorless to slightly yellow solution. Injection: 100 mg/mL solution in a single-dose prefilled syringe. ( 3 )
⛔ Contraindications ▾
4 CONTRAINDICATIONS ILUMYA is contraindicated in patients with a previous serious hypersensitivity reaction to tildrakizumab or to any of the excipients [see Warnings and Precautions (5.1) ]. Serious hypersensitivity reaction to tildrakizumab or to any of the excipients. ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Hypersensitivity: If a serious allergic reaction occurs, discontinue ILUMYA immediately and initiate appropriate therapy. ( 5.1 ) Infections : ILUMYA may increase the risk of infection. Instruct patients to seek medical advice if signs or symptoms of clinically important chronic or acute infection occur.
If a serious infection develops, consider discontinuing ILUMYA until the infection resolves. ( 5.2 ) Pretreatment Evaluation for Tuberculosis (TB): Evaluate for TB prior to initiating treatment. ( 5.3 ) Immunizations : Avoid use of live vaccines.
( 5.4 )
5.1Hypersensitivity Cases of angioedema and urticaria occurred in ILUMYA treated subjects in clinical trials. If a serious hypersensitivity reaction occurs, discontinue ILUMYA immediately and initiate appropriate therapy [see Adverse Reactions (6.1) ].
5.2Infections ILUMYA may increase the risk of infection. Although infections were more common in the ILUMYA group (23%), the difference in frequency of infections between the ILUMYA group and the placebo group (22%) was less than 1% during the placebo-controlled period. However, subjects with active infections or a history of recurrent infections were not included in clinical trials.
Upper respiratory infections occurred more frequently in the ILUMYA group than in the placebo group [see Adverse Reactions (6.1) ] . The rates of serious infections for the ILUMYA group and the placebo group were ≤0.3%. Treatment with ILUMYA should not be initiated in patients with any clinically important active infection until the infection resolves or is adequately treated.
In patients with a chronic infection or a history of recurrent infection, consider the risks and benefits prior to prescribing ILUMYA. Instruct patients to seek medical help if signs or symptoms of clinically important chronic or acute infection occur. If a patient develops a clinically important or serious infection or is not responding to standard therapy, monitor the patient closely and consider discontinuation of ILUMYA until the infection resolves [see Adverse Reactions (6.1) ] .
5.3Pretreatment Evaluation for Tuberculosis Evaluate patients for tuberculosis (TB) infection prior to initiating treatment with ILUMYA. Initiate treatment of latent TB prior to administering ILUMYA. In clinical trials, of 55 subjects with latent TB who were concurrently treated with ILUMYA and appropriate TB prophylaxis, no subjects developed active TB (during the mean follow-up of 56.5 weeks).
One other subject developed TB while receiving ILUMYA. Monitor patients for signs and symptoms of active TB during and after ILUMYA treatment. Consider anti-TB therapy prior to initiation of ILUMYA in patients with a past history of latent or active TB in whom an adequate course of treatment cannot be confirmed.
Do not administer ILUMYA to patients with active TB infection.
5.4Immunizations Prior to initiating therapy with ILUMYA, consider completion of all age appropriate immunizations according to current immunization guidelines. Avoid the use of live vaccines in patients treated with ILUMYA. No data are available on the response to live or inactive vaccines.
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following serious adverse reactions are discussed elsewhere in the labeling: Hypersensitivity Reactions [see Warnings and Precautions (5.1) ] Infections [see Warnings and Precautions (5.2) ] Most common (≥1%) adverse reactions associated with ILUMYA treatment are upper respiratory infections, injection site reactions, and diarrhea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Sun Pharmaceutical Industries, Inc. at 1-800-818-4555 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical Trials Experience Because clinical trials are conducted under widely varying 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. Plaque Psoriasis In clinical trials, a total of 1994 subjects with plaque psoriasis were treated with ILUMYA, of which 1083 subjects were treated with ILUMYA 100 mg. Of these, 672 subjects were exposed for at least 12 months, 587 for 18 months, and 469 for 24 months.
Data from three placebo-controlled trials (Trials 1, 2, and 3) in 705 subjects (mean age 46 years, 71% males, 81% white) were pooled to evaluate the safety of ILUMYA (100 mg administered subcutaneously at Weeks 0 and 4, followed by every 12 weeks [Q12W]) [see Clinical Studies (14) ] . Placebo-Controlled Period (Weeks 0-16 of Trial 1 and Weeks 0-12 of Trials 2 and 3) Table 1 summarizes the adverse reactions that occurred at a rate of at least 1% and at a higher rate in the ILUMYA group than in the placebo group. Table 1: Adverse Reactions Occurring in ≥1% of Subjects in the ILUMYA Group and More Frequently than in the Placebo Group in the Plaque Psoriasis Trials 1, 2, and 3 * Upper respiratory infections include nasopharyngitis, upper respiratory tract infection, viral upper respiratory tract infection, and pharyngitis. † Injection site reactions include injection site urticaria, pruritus, pain, reaction, erythema, inflammation, edema, swelling, bruising, hematoma, and hemorrhage.

Cases of angioedema and urticaria were reported in ILUMYA-treated subjects in clinical trials . Safety through Week 260 The safety profile of ILUMYA through Week 260 of the open-label extension periods of Trial 2 and Trial 3 was consistent with the safety profile observed during the double-blind periods .
Psoriasis of the Scalp The safety of ILUMYA was assessed in a multicenter, randomized, double-blind, placebo-controlled trial (Trial 4) in 231 subjects with psoriasis of the scalp [ see Clinical Studies (14) ]. No new safety signals were identified through follow-up to Week 72. Psoriasis of the Nail The safety of ILUMYA was assessed in a multicenter, randomized, double-blind, placebo-controlled trial (Trial 5) in 99 subjects with psoriasis of the nail [ see Clinical Studies (14) ].
No new safety signals were identified through Week 28.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors outcomes in women with plaque psoriasis who become pregnant while being treated with ILUMYA during pregnancy. These patients can enroll in this registry by calling MotherToBaby a service of the Organization of Teratology Information Specialists (OTIS) at 1-866-626-6847 or by visiting the website https://mothertobaby.org/ongoing-study/ilumya-tildrakizumab-asmn. Risk Summary Available data from clinical trials, published literature, and pharmacovigilance with ILUMYA use in pregnant women are insufficient to inform a drug associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes.
Monoclonal antibodies are actively transported across the placenta (see Clinical Considerations). An embryofetal developmental study conducted with tildrakizumab in pregnant monkeys revealed no treatment-related effects to the developing fetus when tildrakizumab was administered subcutaneously during organogenesis to near parturition at doses up to 159 times the maximum recommended human dose (MRHD). When dosing was continued until parturition, an increase in neonatal death was observed at 59 times the MRHD (see Data).
The clinical significance of this nonclinical finding is unknown. 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 2-4% and 15-20%, respectively. 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, ILUMYA may be present in infants exposed in utero .
The potential clinical impact of tildrakizumab exposure in infants exposed in utero should be considered. Data Animal Data In an embryofetal developmental study, subcutaneous doses up to 300 mg/kg tildrakizumab were administered to pregnant cynomolgus monkeys once every two weeks during organogenesis to gestation day 118 (22 days from parturition). No maternal or embryofetal toxicities were observed at doses up to 300 mg/kg (159 times the MRHD of 100 mg, based on AUC comparison).
Tildrakizumab crossed the placenta in monkeys. In a pre- and postnatal developmental study, subcutaneous doses up to 100 mg/kg tildrakizumab were administered to pregnant cynomolgus monkeys once every two weeks from gestation day 50 to parturition. Neonatal deaths occurred in the offspring of one control monkey, two monkeys at 10 mg/kg dose (6 times the MRHD based on AUC comparison), and four monkeys at 100 mg/kg dose (59 times the MRHD based on AUC comparison).
The clinical significance of these nonclinical findings is unknown. No tildrakizumab-related adverse effects were noted in the remaining infants from birth through 6 months of age.
8.2Lactation Risk Summary There are no data on the presence of tildrakizumab in human milk, the effects on the breastfed infant, or the effects on milk production. Human IgG is known to be present in human milk. Tildrakizumab was detected in the milk of monkeys [ see Data ] .
The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for ILUMYA and any potential adverse effects on the breastfed child from ILUMYA or from the underlying maternal condition. Data Animal Data Tildrakizumab was detected in breast milk of monkeys in the pre- and postnatal developmental study described in 8.1. The mean tildrakizumab concentrations in milk were approximately 0.09 – 0.2% of that in serum on postpartum days 28 and 91.

8.5Geriatric Use A total of 1083 subjects were exposed to ILUMYA 100 mg during Phase 2 and 3 trials. A total of 92 subjects were 65 years or older, and 17 subjects were 75 years or older. Although no differences in safety or efficacy were observed between older and younger subjects, the number of subjects aged 65 and over is not sufficient to determine whether they responded differently from younger subjects [see Clinical Pharmacology (12.3) ] .
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Tildrakizumab is a humanized IgG1/k monoclonal antibody that selectively binds to the p19 subunit of IL-23 and inhibits its interaction with the IL-23 receptor. IL-23 is a naturally occurring cytokine that is involved in inflammatory and immune responses. Tildrakizumab inhibits the release of proinflammatory cytokines and chemokines.
12.2Pharmacodynamics No formal pharmacodynamics studies have been conducted with ILUMYA.
12.3Pharmacokinetics Tildrakizumab pharmacokinetics increases proportionally over a dose range from 50 mg to 200 mg (0.5 to 2 times the approved recommended dosage) following subcutaneous administration in subjects with plaque psoriasis. Steady-state concentrations were achieved by Week 16 following subcutaneous administration of tildrakizumab at Weeks 0, 4, and every 12 weeks thereafter. At the 100 mg dose at Week 16, the mean (± SD) steady-state trough concentrations ranged from 1.22 ± 0.94 mcg/mL to 1.47 ± 1.12 mcg/mL.
The geometric mean (CV%) steady-state C max was 8.1 mcg/mL (34%). Absorption The absolute bioavailability of tildrakizumab was estimated to be 73-80% following subcutaneous injection. The peak concentration (C max ) was reached by approximately 6 days.
Distribution The geometric mean (CV%) volume of distribution is
10.8L (24%). Elimination The geometric mean (CV%) systemic clearance was
0.32L/day (38%) and the half-life was approximately 23 days (23%). Metabolism The metabolic pathway of tildrakizumab has not been characterized. As a humanized IgG1/k monoclonal antibody, tildrakizumab is expected to be degraded into small peptides and amino acids via catabolic pathways in a manner similar to endogenous IgG.
Specific Populations No clinically significant differences in the pharmacokinetics of tildrakizumab were observed based on age (≥18 years). No specific studies have been conducted to determine the effect of renal or hepatic impairment on the pharmacokinetics of tildrakizumab. Body Weight Tildrakizumab concentrations were lower in subjects with higher body weight.
Drug Interaction Studies Cytochrome P450 Substrates The AUC inf of dextromethorphan (CYP2D6 substrate) increased by 20% when used concomitantly with tildrakizumab 200 mg (two times the approved recommended dose) administered subcutaneously at Weeks 0 and 4 in subjects with plaque psoriasis. No clinically significant changes in AUC inf of caffeine (CYP1A2 substrate), warfarin (CYP2C9 substrate), omeprazole (CYP2C19 substrate), and midazolam (CYP3A4 substrate) were observed.
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 the incidence of anti-drug antibodies in the studies described below with the incidence of anti-drug antibodies in other studies, including those of ILUMYA or of other tildrakizumab products. In pooled Phase 2b and Phase 3 analyses, 6.5% (26/400) of subjects treated with tildrakizumab 100 mg up to week 64 developed antibodies to tildrakizumab.
Of the subjects who developed antibodies to tildrakizumab, 38.4% (10/26 subjects) had neutralizing antibodies. This represents 2.5% (10/400) of all subjects receiving tildrakizumab. In pooled Phase 3 analyses, 8.3% (51/615) of subjects treated with tildrakizumab 100 mg dose up to 420 weeks developed antibodies to tildrakizumab.
Of the tildrakizumab-treated subjects who developed antibodies to tildrakizumab, 37.3% (19/51 subjects) had antibodies that were classified as neutralizing, which represents 3.0% (19/615) of all tildrakizumab-treated subjects. Development of neutralizing antibodies to tildrakizumab was associated with lower serum tildrakizumab concentrations. Subjects with neutralizing antibodies had numerically lower efficacy; however, the full impact of neutralizing antibodies on efficacy could not be adequately assessed.
