Availability & biosimilar status
1 biosimilar and 7 interchangeables are FDA-licensed for this reference biologic — see the list below. (Biologics have no small-molecule generics.)
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 16, 2036 |

⛔ Contraindications ▾
4 CONTRAINDICATIONS SELARSDI is contraindicated in patients with clinically significant hypersensitivity to ustekinumab products or to any of the excipients in SELARSDI [see Warnings and Precautions ( 5.5 )]. Clinically significant hypersensitivity to ustekinumab products or to any of the excipients in SELARSDI. (4)
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Infections: Serious infections have occurred. Avoid starting SELARSDI during any clinically important active infection. If a serious infection or clinically significant infection develops, discontinue SELARSDI until the infection resolves.
( 5.1 ) Theoretical Risk for Particular Infections : Serious infections from mycobacteria, salmonella, and Bacillus Calmette-Guerin (BCG) vaccinations have been reported in patients genetically deficient in IL-12/IL-23. Consider diagnostic tests for these infections as dictated by clinical circumstances. ( 5.2 ) Tuberculosis (TB): Evaluate patients for TB prior to initiating treatment with SELARSDI.
Initiate treatment of latent TB before administering SELARSDI. ( 5.3 ) Malignancies: Ustekinumab products may increase risk of malignancy. The safety of ustekinumab products in patients with a history of or a known malignancy has not been evaluated.
( 5.4 ) Hypersensitivity Reactions: If an anaphylactic or other clinically significant hypersensitivity reaction occurs, institute appropriate therapy and discontinue SELARSDI. (5.5) Posterior Reversible Encephalopathy Syndrome (PRES): If PRES is suspected, treat promptly, and discontinue SELARSDI. ( 5.6 ) Immunizations: Avoid use of live vaccines in patients during treatment with SELARSDI.
( 5.7 ) Noninfectious Pneumonia: Cases of interstitial pneumonia, eosinophilic pneumonia, and cryptogenic organizing pneumonia have been reported during post-approval use of ustekinumab products. If diagnosis is confirmed, discontinue SELARSDI and institute appropriate treatment. ( 5.8 )
5.1Infections Ustekinumab products may increase the risk of infections and reactivation of latent infections. Serious bacterial, mycobacterial, fungal, and viral infections were observed in patients receiving ustekinumab products [see Adverse Reactions ( 6.1 , 6.3 )]. Serious infections requiring hospitalization, or otherwise clinically significant infections, reported in clinical trials included the following: Plaque Psoriasis: diverticulitis, cellulitis, pneumonia, appendicitis, cholecystitis, sepsis, osteomyelitis, viral infections, gastroenteritis, and urinary tract infections.
Psoriatic arthritis: cholecystitis. Crohn’s disease: anal abscess, gastroenteritis, ophthalmic herpes zoster, pneumonia, and listeria meningitis. Ulcerative colitis: gastroenteritis, ophthalmic herpes zoster, pneumonia, and listeriosis.
Avoid initiating treatment with SELARSDI in patients with any clinically important active infection until the infection resolves or is adequately treated. Consider the risks and benefits of treatment prior to initiating use of SELARSDI in patients with a chronic infection or a history of recurrent infection. Instruct patients to seek medical advice if signs or symptoms suggestive of an infection occur while on treatment with SELARSDI and discontinue SELARSDI for serious or clinically significant infections until the infection resolves or is adequately treated.
5.2Theoretical Risk for Vulnerability to Particular Infections Individuals genetically deficient in IL-12/IL-23 are particularly vulnerable to disseminated infections from mycobacteria (including nontuberculous, environmental mycobacteria), salmonella (including nontyphi strains), and Bacillus Calmette-Guerin (BCG) vaccinations. Serious infections and fatal outcomes have been reported in such patients. It is not known whether patients with pharmacologic blockade of IL-12/IL-23 from treatment with ustekinumab products may be susceptible to these types of infections.
Consider appropriate diagnostic testing, (e.g., tissue culture, stool culture, as dictated by clinical circumstances).
5.3Pre-treatment Evaluation for Tuberculosis Evaluate patients for tuberculosis infection prior to initiating treatment with SELARSDI. Avoid administering SELARSDI to patients with active tuberculosis infection. Initiate treatment of latent tuberculosis prior to administering SELARSDI. Consider anti-tuberculo… [Excerpted — this section continues on DailyMed.]

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. Adult Subjects with Plaque Psoriasis The safety data reflect exposure to ustekinumab in 3117 adult subjects with plaque psoriasis, including 2414 exposed for at least 6 months, 1855 exposed for at least one year, 1653 exposed for at least two years, 1569 exposed for at least three years, 1482 exposed for at least four years and 838 exposed for at least five years.
Table 5 summarizes the adverse reactions that occurred at a rate of at least 1% with higher rates in the ustekinumab groups during the placebo-controlled period of Ps STUDY 1 and Ps STUDY 2 [see Clinical Studies ( 14 )]. Table 5: Adverse Reactions, Reported by ≥1% of Subjects with Plaque Psoriasis and at Higher Rates in the ustekinumab groups through Week 12 in Ps STUDY 1 and Ps STUDY 2 Ustekinumab Placebo 45 mg 90 mg Subjects treated 665 664 666 Nasopharyngitis 51 (8%) 56 (8%) 49 (7%) Upper respiratory tract infection 30 (5%) 36 (5%) 28 (4%) Headache 23 (3%) 33 (5%) 32 (5%) Fatigue 14 (2%) 18 (3%) 17 (3%) Back pain 8 (1%) 9 (1%) 14 (2%) Dizziness 8 (1%) 8 (1%) 14 (2%) Pharyngolaryngeal pain 7 (1%) 9 (1%) 12 (2%) Pruritus 9 (1%) 10 (2%) 9 (1%) Injection site erythema 3 (<1%) 6 (1%) 13 (2%) Myalgia 4 (1%) 7 (1%) 8 (1%) Depression 3 (<1%) 8 (1%) 4 (1%) Adverse reactions that occurred at rates less than 1% in the controlled period of Ps STUDIES 1 and 2 through week 12 included: cellulitis, herpes zoster, diverticulitis, and certain injection site reactions (pain, swelling, pruritus, induration, hemorrhage, bruising, and irritation).
One case of PRES occurred during adult plaque psoriasis clinical trials [see Warnings and Precautions ( 5.6 )]. Infections In the placebo-controlled period of clinical trials of subjects with plaque psoriasis (average follow-up of 12.6 weeks for placebo-treated subjects and 13.4 weeks for ustekinumab-treated subjects), 27% of ustekinumab-treated subjects reported infections (1.39 per patient-years of follow-up) compared with 24% of placebo-treated subjects (1.21 per patient-years of follow-up). Serious infections occurred in 0.3% of ustekinumab-treated subjects (0.01 per patient-years of follow-up) and in 0.4% of placebo-treated subjects (0.02 per patient-years of follow-up) [see Warnings and Precautions (5.1)].
In the controlled and non-controlled portions of plaque psoriasis clinical trials (median follow-up of 3.2 years), representing 8998 patient-years of exposure, 72.3% of ustekinumab-treated subjects reported infections (0.87 per patient-years of follow-up). Serious infections were reported in 2.8% of subjects (0.01 per patient-years of fol… [Excerpted — this section continues on DailyMed.]
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS
7.1Concomitant Therapies In plaque psoriasis trials the safety of ustekinumab products in combination with immunosuppressive agents or phototherapy has not been evaluated. In psoriatic arthritis trials, concomitant MTX use did not appear to influence the safety or efficacy of ustekinumab. In Crohn’s disease and ulcerative colitis induction trials, immunomodulators (6-MP, AZA, MTX) were used concomitantly in approximately 30% of subjects and corticosteroids were used concomitantly in approximately 40% and 50% of Crohn’s disease and ulcerative colitis subjects, respectively.
Use of these concomitant therapies did not appear to influence the overall safety or efficacy of ustekinumab.
7.2CYP450 Substrates The formation of CYP450 enzymes can be suppressed by increased levels of certain cytokines (e.g., IL-1, IL-6, TNFα, IFN) during chronic inflammation. Thus, use of ustekinumab products, an antagonist of IL-12 and IL-23, could normalize the formation of CYP450 enzymes. Upon initiation or discontinuation of SELARSDI in patients who are receiving concomitant CYP450 substrates, particularly those with a narrow therapeutic index, consider monitoring for therapeutic effect or drug concentration and adjust the individual dosage of the CYP substrate as needed.
See the prescribing information of specific CYP substrates . A CYP-mediated drug interaction effect was not observed in subjects with Crohn’s disease [see Clinical Pharmacology (12.3)] .
7.3Allergen Immunotherapy Ustekinumab products have not been evaluated in patients who have undergone allergy immunotherapy. Ustekinumab products may decrease the protective effect of allergen immunotherapy (decrease tolerance) which may increase the risk of an allergic reaction to a dose of allergen immunotherapy. Therefore, caution should be exercised in patients receiving or who have received allergen immunotherapy, particularly for anaphylaxis.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary Limited data from observational studies, published case reports, and postmarketing surveillance on the use of ustekinumab products during pregnancy are insufficient to inform a drug associated risk of major birth defects, miscarriage, and other adverse maternal or fetal outcomes. Transport of human IgG antibody across the placenta increases as pregnancy progresses and peaks during the third trimester; therefore, ustekinumab products may be transferred to the developing fetus [see Clinical Considerations] .
In animal reproductive and developmental toxicity studies, no adverse developmental effects were observed in offspring after administration of ustekinumab to pregnant monkeys at exposures greater than 100 times the maximum recommended human dose (MRHD). The background risk of major birth defects and miscarriage for the indicated population(s) are 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 of clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions Because ustekinumab products may theoretically interfere with immune response to infections, consider risks and benefits prior to administering live vaccines to infants exposed to SELARSDI in utero. There are insufficient data regarding exposed infant serum levels of ustekinumab products at birth and the duration of persistence of ustekinumab products in infant serum after birth.
Although a specific timeframe to delay administration of live attenuated vaccines in infants exposed in utero is unknown, consider the risks and benefits of delaying a minimum of 6 months after birth because of the clearance of the product. Data Animal Data Ustekinumab was tested in two embryo-fetal development toxicity studies in cynomolgus monkeys. No teratogenic or other adverse developmental effects were observed in fetuses from pregnant monkeys that were administered ustekinumab subcutaneously twice weekly or intravenously weekly during the period of organogenesis.
Serum concentrations of ustekinumab in pregnant monkeys were greater than 100 times the serum concentration in patients treated subcutaneously with 90 mg of ustekinumab weekly for 4 weeks. In a combined embryo-fetal development and pre- and post-natal development toxicity study, pregnant cynomolgus monkeys were administered subcutaneous doses of ustekinumab twice weekly at exposures greater than 100 times the MRHD from the beginning of organogenesis to Day 33 after delivery. Neonatal deaths occurred in the offspring of one monkey administered ustekinumab at 22.5 mg/kg and one monkey dosed at 45 mg/kg.
No ustekinumab-related-effects on functional, morphological, or immunological development were observed in the neonates from birth through six months of age.
8.2Lactation Risk Summary Limited data from published literature suggests that ustekinumab is present in human breast milk. There are no available data on the effects of ustekinumab products on milk production. The effects of local gastrointestinal exposure and limited systemic exposure in the breastfed infant to ustekinumab products are unknown.
No adverse effects on the breastfed infant causally related to ustekinumab products have been identified in the published literature or postmarketing experience. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for SELARSDI and any potential adverse effects on the breastfed child from SELARSDI or from the underlying maternal condition.
8.4Pediatric Use Plaque Psoriasis The safety and effectiveness of SELARSDI have been established for the treatment of moderate to severe plaque psoriasis in pediatric patients 6 to 17 years of age who are candidates for phototherapy or systemic therapy.

🧒 Pediatric Use ▾
8.4Pediatric Use Plaque Psoriasis The safety and effectiveness of SELARSDI have been established for the treatment of moderate to severe plaque psoriasis in pediatric patients 6 to 17 years of age who are candidates for phototherapy or systemic therapy. Use of SELARSDI in pediatric patients 12 to less than 17 years of age is supported by evidence from a multicenter, randomized, 60week trial (Ps STUDY 3) of ustekinumab that included a 12week, double-blind, placebo-controlled, parallel group portion, in 110 pediatric subjects 12 years of age and older [see Adverse Reactions (6.1), Clinical Studies (14.2)].
Use of SELARSDI in pediatric patients 6 to 11 years of age is supported by evidence from an open-label, single-arm, efficacy, safety, and pharmacokinetics trial (Ps STUDY 4) of ustekinumab in 44 subjects [see Adverse Reactions (6.1), Pharmacokinetics (12.3)]. The safety and effectiveness of SELARSDI have not been established in pediatric patients less than 6 years of age with plaque psoriasis. Psoriatic Arthritis The safety and effectiveness of SELARSDI have been established for treatment of psoriatic arthritis in pediatric patients 6 to 17 years old.
Use of SELARSDI in these age groups is supported by evidence from adequate and well controlled trials of ustekinumab in adults with psoriasis and PsA, pharmacokinetic data from adult subjects with psoriasis, adult subjects with PsA and pediatric subjects with psoriasis, and safety data of ustekinumab from two clinical trials in 44 pediatric subjects 6 to 11 years old with psoriasis and 110 pediatric subjects 12 to 17 years old with psoriasis. The observed pre-dose (trough) concentrations are generally comparable between adult subjects with psoriasis, adult subjects with PsA and pediatric subjects with psoriasis, and the PK exposure is expected to be comparable between adult and pediatric subjects with PsA [see Adverse Reactions (6.1), Clinical Pharmacology (12.3), and Clinical Studies (14.1, 14.2, 14.3)] .
The safety and effectiveness of SELARSDI have not been established in pediatric patients less than 6 years old with psoriatic arthritis. Crohn’s Disease and Ulcerative Colitis The safety and effectiveness of SELARSDI have not been established in pediatric patients with Crohn’s disease or ulcerative colitis.
🧓 Geriatric Use ▾
8.5Geriatric Use Of the 6709 subjects exposed to ustekinumab, a total of 340 were 65 years of age or older (183 subjects with plaque psoriasis, 65 subjects with psoriatic arthritis, 58 subjects with Crohn’s disease, and 34 subjects with ulcerative colitis), and 40 subjects were 75 years of age or older. Clinical trials of ustekinumab did not include sufficient numbers of subjects 65 years of age and older to determine whether they respond differently from younger adult subjects.
🆘 Overdosage ▾
10 OVERDOSAGE Single doses up to 6 mg/kg intravenously have been administered in clinical trials without dose-limiting toxicity. In case of overdosage, monitor the patient for any signs or symptoms of adverse reactions or effects and institute appropriate symptomatic treatment immediately. Consider contacting the Poison Help line (1-800- 222-1222) or a medical toxicologist for additional overdose management recommendations.

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Ustekinumab products are human IgG1κ monoclonal antibodies that bind with specificity to the p40 protein subunit used by both the IL-12 and IL-23 cytokines. IL-12 and IL-23 are naturally occurring cytokines that are involved in inflammatory and immune responses, such as natural killer cell activation and CD4+ T-cell differentiation and activation. In in vitro models, ustekinumab products were shown to disrupt IL-12 and IL-23 mediated signaling and cytokine cascades by disrupting the interaction of these cytokines with a shared cell- surface receptor chain, IL-12Rβ1.
The cytokines IL-12 and IL-23 have been implicated as important contributors to the chronic inflammation that is a hallmark of Crohn’s disease and ulcerative colitis. In animal models of colitis, genetic absence or antibody blockade of the p40 subunit of IL-12 and IL-23, the target of ustekinumab products, was shown to be protective.
12.2Pharmacodynamics Plaque Psoriasis In a small exploratory trial, a decrease was observed in the expression of mRNA of its molecular targets IL-12 and IL-23 in lesional skin biopsies measured at baseline and up to two weeks post-treatment in subjects with plaque psoriasis. Ulcerative Colitis In both trial UC-1 (induction) and trial UC-2 (maintenance), a positive relationship was observed between exposure and rates of clinical remission, clinical response, and endoscopic improvement. The response rate approached a plateau at the ustekinumab exposures associated with the recommended dosing regimen for maintenance treatment [see Clinical Studies ( 14.5 )] .
12.3Pharmacokinetics Absorption In adult subjects with plaque psoriasis, the median time to reach the maximum serum concentration (T max ) was 13.5 days and 7 days, respectively, after a single subcutaneous administration of 45 mg (N=22) and 90 mg (N=24) of ustekinumab. In healthy subjects (N=30), the median T max value (8.5 days) following a single subcutaneous administration of 90 mg of ustekinumab was comparable to that observed in subjects with plaque psoriasis. Following multiple subcutaneous doses of ustekinumab in adult subjects with plaque psoriasis, steady-state serum concentrations of ustekinumab were achieved by Week 28.
The mean (±SD) steady-state trough serum ustekinumab concentrations were 0.69 ± 0.69 mcg/mL for subjects less than or equal to 100 kg receiving a 45 mg dose and 0.74 ± 0.78 mcg/mL for subjects greater than 100 kg receiving a 90 mg dose. There was no apparent accumulation in serum ustekinumab concentration over time when given subcutaneously every 12 weeks. Following the recommended intravenous induction dose, mean ±SD peak serum ustekinumab concentration was 125.2 ± 33.6 mcg/mL in subjects with Crohn’s disease, and 129.1 ± 27.6 mcg/mL in subjects with ulcerative colitis.
Starting at Week 8, the recommended subcutaneous maintenance dosing of 90 mg ustekinumab was administered every 8 weeks. Steady state ustekinumab concentration was achieved by the start of the second maintenance dose. There was no apparent accumulation in ustekinumab concentration over time when given subcutaneously every 8 weeks.
Mean ±SD steady-state trough concentration was 2.5 ± 2.1 mcg/mL in subjects with Crohn’s disease, and 3.3 ± 2.3 mcg/mL in subjects with ulcerative colitis for 90 mg ustekinumab administered every 8 weeks. Distribution Population pharmacokinetic analyses showed that the volume of distribution of ustekinumab in the central compartment was
2.7L (95% CI: 2.69, 2.78) in subjects with Crohn’s disease and
3.0L (95% CI: 2.96, 3.07) in subjects with ulcerative colitis. The total volume of distribution at steady-state was
4.6 L in subjects with Crohn’s disease and
4.4L in subjects with ulcerative colitis. Elimination The mean (±SD) half-life ranged from 14.9 ± 4.6 to 45.6 ± 80.2 days across all plaque psoriasis trials following subcutaneous administration.

💬 Medication Guide ▾
MEDICATION GUIDE SELARSDI™ (seh-LARS-dee) (ustekinumab-aekn) injection, for subcutaneous or intravenous use What is the most important information I should know about SELARSDI? SELARSDI is a medicine that affects your immune system. SELARSDI can increase your risk of having serious side effects, including: Serious infections.
SELARSDI may lower the ability of your immune system to fight infections and may increase your risk of infections. Some people have serious infections while taking ustekinumab products, including tuberculosis (TB), and infections caused by bacteria, fungi, or viruses. Some people have to be hospitalized for treatment of their infection.
Your doctor should check you for TB before starting SELARSDI. If your doctor feels that you are at risk for TB, you may be treated with medicine for TB before you begin treatment with SELARSDI and during treatment with SELARSDI. Your doctor should watch you closely for signs and symptoms of TB while you are being treated with SELARSDI.
You should not start taking SELARSDI if you have any kind of infection unless your doctor says it is okay. Before starting SELARSDI, tell your doctor if you: think you have an infection or have symptoms of an infection such as: fever, sweat, or chills muscle aches cough shortness of breath blood in phlegm weight loss warm, red, or painful skin or sores on your body diarrhea or stomach pain burning when you urinate or urinate more often than normal feel very tired are being treated for an infection or have any open cuts. get a lot of infections or have infections that keep coming back. have TB, or have been in close contact with someone with TB.
After starting SELARSDI, call your doctor right away if you have any symptoms of an infection (see above). These may be signs of infections such as chest infections, or skin infections or shingles that could have serious complications. SELARSDI can make you more likely to get infections or make an infection that you have worse.
People who have a genetic problem where the body does not make any of the proteins interleukin 12 (IL-12) and interleukin 23 (IL-23) are at a higher risk for certain serious infections. These infections can spread throughout the body and cause death. People who take SELARSDI may also be more likely to get these infections.
Cancers. SELARSDI may decrease the activity of your immune system and increase your risk for certain types of cancers. Tell your doctor if you have ever had any type of cancer.
Some people who are receiving ustekinumab products and have risk factors for skin cancer have developed certain types of skin cancers. During your treatment with SELARSDI, tell your doctor if you develop any new skin growths. Posterior Reversible Encephalopathy Syndrome (PRES).
PRES is a rare condition that affects the brain and can cause death. The cause of PRES is not known. If PRES is found early and treated, most people recover.
Tell your doctor right away if you have any new or worsening medical problems including: headache confusion seizures vision problems What is SELARSDI? SELARSDI is a prescription medicine used to treat: adults and children 6 years and older with moderate or severe psoriasis who may benefit from taking injections or pills (systemic therapy) or phototherapy (treatment using ultraviolet light alone or with pills). adults and children 6 years and older with active psoriatic arthritis. adults 18 years and older with moderately to severely active Crohn’s disease. adults 18 years and older with moderately to severely active ulcerative colitis.
It is not known if SELARSDI is safe and effective in children less than 6 years of age. Do not take SELARSDI if you are allergic to ustekinumab products or any of the ingredients in SELARSDI. See the end of this Medication Guide for a complete list of ingredients in SELARSDI.

4.6 L in subjects with Crohn’s disease and
4.4L in subjects with ulcerative colitis. Elimination The mean (±SD) half-life ranged from 14.9 ± 4.6 to 45.6 ± 80.2 days across all plaque psoriasis trials following subcutaneous administration. Population pharmacokinetic analyses showed that the clearance of ustekinumab was
0.19L/day (95% CI: 0.185, 0.197) in subjects with Crohn’s disease and
0.19L/day (95% CI: 0.179, 0.192) in subjects with ulcerative colitis with an estimated median terminal half-life of approximately 19 days for both IBD (Crohn’s disease and ulcerative colitis) populations. These results indicate the pharmacokinetics of ustekinumab were similar between subjects with Crohn’s disease and ulcerative colitis. Metabolism The metabolic pathway of ustekinumab products have not been characterized.
As a human IgG1κ monoclonal antibody, ustekinumab products are expected to be degraded into small peptides and amino acids via catabolic pathways in the same manner as endogenous IgG. Specific Populations Weight When given the same dose, subjects with plaque psoriasis or psoriatic arthritis weighing more than 100 kg had lower median serum ustekinumab concentrations compared with those subjects weighing 100 kg or less. The median trough serum concentrations of ustekinumab in subjects of higher weight (greater than 100 kg) in the 90 mg group were comparable to those in subjects of lower weight (100 kg or less) in the 45 mg group.
Age: Geriatric Population A population pharmacokinetic analysis (N=106/1937 subjects with plaque psoriasis greater than or equal to 65 years old) was performed to evaluate the effect of age on the pharmacokinetics of ustekinumab. There were no apparent changes in pharmacokinetic parameters (clearance and volume of distribution) in subjects older than 65 years old.

🔬 Clinical Studies ▾
14 CLINICAL STUDIES
14.1Adult Plaque Psoriasis Two multicenter, randomized, double-blind, placebo-controlled trials (Ps STUDY 1 and Ps STUDY 2) enrolled a total of 1996 subjects 18 years of age and older with plaque psoriasis who had a minimum body surface area involvement of 10%, and Psoriasis Area and Severity Index (PASI) score ≥12, and who were candidates for phototherapy or systemic therapy. Subjects with guttate, erythrodermic, or pustular psoriasis were excluded from the trials. Ps STUDY 1 enrolled 766 subjects and Ps STUDY 2 enrolled 1230 subjects.
The trials had the same design through Week 28. In both trials, subjects were randomized in equal proportion to placebo, 45 mg or 90 mg of ustekinumab. Subjects randomized to ustekinumab received 45 mg or 90 mg doses, regardless of weight, at Weeks 0, 4, and 16.
Subjects randomized to receive placebo at Weeks 0 and 4 crossed over to receive ustekinumab (either 45 mg or 90 mg) at Weeks 12 and 16. In both trials, subjects in all treatment groups had a median baseline PASI score ranging from approximately 17 to 18. Baseline PGA score was marked or severe in 44% of subjects in Ps STUDY 1 and 40% of subjects in Ps STUDY 2.
Approximately two-thirds of all subjects had received prior phototherapy, 69% had received either prior conventional systemic or biologic therapy for the treatment of psoriasis, with 56% receiving prior conventional systemic therapy and 43% receiving prior biologic therapy. A total of 28% of subjects had a history of psoriatic arthritis. In both trials, the endpoints were the proportion of subjects who achieved at least a 75% reduction in PASI score (PASI 75) from baseline to Week 12 and treatment success (cleared or minimal) on the Physician’s Global Assessment (PGA).
The PGA is a 6-category scale ranging from 0 (cleared) to 5 (severe) that indicates the physician’s overall assessment of psoriasis focusing on plaque thickness/induration, erythema, and scaling. Clinical Response The results of Ps STUDY 1 and Ps STUDY 2 are presented in Table 8 below. Table 8: Clinical Outcomes at Week 12 in Adults with Plaque Psoriasis in Ps STUDY 1 and Ps STUDY 2 Ps STUDY 1 Ps STUDY 2 Ustekinumab Ustekinumab Placebo 45 mg 90 mg Placebo 45 mg 90 mg Subjects randomized 255 255 256 410 409 411 PASI 75 response 8 (3%) 171 (67%) 170 (66%) 15 (4%) 273 (67%) 311 (76%) PGA of Cleared or Minimal 10 (4%) 151 (59%) 156 (61%) 18 (4%) 277 (68%) 300 (73%) Examination of age, gender, and race subgroups did not identify differences in response to ustekinumab among these subgroups.
In subjects who weighed 100 kg or less, response rates were comparable with both the 45 mg and 90 mg doses; however, in subjects who weighed greater than 100 kg, higher response rates were seen with 90 mg dosing compared with 45 mg dosing (Table 9 below).

Subjects in Ps STUDY 1 who were PASI 75 responders at both Weeks 28 and 40 were re-randomized at Week 40 to either continued dosing of ustekinumab (ustekinumab at Week 40) or to withdrawal of therapy (placebo at Week 40). At Week 52, 89% (144/162) of subjects re-randomized to ustekinumab treatment were PASI 75 responders compared with 63% (100/159) of subjects re-randomized to placebo (treatment withdrawal after Week 28 dose). The median time to loss of PASI 75 response among the subjects randomized to treatment withdrawal was 16 weeks.

🧪 Nonclinical Toxicology ▾
13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Animal studies have not been conducted to evaluate the carcinogenic or mutagenic potential of ustekinumab products. Published literature showed that administration of murine IL-12 caused an anti-tumor effect in mice that contained transplanted tumors and IL-12/IL-23p40 knockout mice or mice treated with anti-IL-12/IL-23p40 antibody had decreased host defense to tumors. Mice genetically manipulated to be deficient in both IL-12 and IL-23 or IL-12 alone developed UV-induced skin cancers earlier and more frequently compared to wild-type mice.
The relevance of these experimental findings in mouse models for malignancy risk in humans is unknown. No effects on fertility were observed in male cynomolgus monkeys that were administered ustekinumab at subcutaneous doses up to 45 mg/kg twice weekly (45 times the MRHD on a mg/kg basis) prior to and during the mating period. However, fertility and pregnancy outcomes were not evaluated in mated females.
No effects on fertility were observed in female mice that were administered an analogous IL-12/IL-23p40 antibody by subcutaneous administration at doses up to 50 mg/kg, twice weekly, prior to and during early pregnancy.
13.2Animal Toxicology and/or Pharmacology In a 26-week toxicology study, one out of 10 monkeys subcutaneously administered 45 mg/kg ustekinumab twice weekly for 26 weeks had a bacterial infection.
