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 |

⛔ Contraindications ▾
4 CONTRAINDICATIONS PYZCHIVA is contraindicated in patients with clinically significant hypersensitivity to ustekinumab products or to any of the excipients in PYZCHIVA [see Warnings and Precautions ( 5.5 )] . Clinically significant hypersensitivity to ustekinumab products or to any of the excipients in PYZCHIVA. ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Infections: Serious infections have occurred. Avoid starting PYZCHIVA during any clinically important active infection. If a serious infection or clinically significant infection develops, discontinue PYZCHIVA 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 PYZCHIVA.
Initiate treatment of latent TB before administering PYZCHIVA. ( 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 ) Serious Hypersensitivity Reactions: If a severe or other clinically significant hypersensitivity reaction occurs, discontinue PYZCHIVA immediately and initiate appropriate medical treatment. ( 5.5 ) Posterior Reversible Encephalopathy Syndrome (PRES): If PRES is suspected, treat promptly and discontinue PYZCHIVA. ( 5.6 ) Immunizations: Avoid use of live vaccines in patients during treatment with PYZCHIVA.
( 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 PYZCHIVA 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 PYZCHIVA 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 PYZCHIVA 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 PYZCHIVA and discontinue PYZCHIVA 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 PYZCHIVA. Avoid administering PYZCHIVA to patients with active tuberculosis infection. Initiate treatment of latent tuberculosis prior to administering PYZCHIVA.

Biosimilarity of PYZCHIVA has been demonstrated for the condition(s) of use (e.g., indication(s), dosing regimen(s)), strength(s), dosage form(s), and route(s) of administration described in its Full Prescribing Information
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 clinical trials in adult subjects with plaque psoriasis [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 subjects receiving placebo 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 subjects receiving placebo (1.21 per patient-years… [Excerpted — this section continues on DailyMed.]
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS
7.1Concomitant Therapies In trials in subjects with plaque psoriasis the safety of ustekinumab products in combination with immunosuppressive agents or phototherapy has not been evaluated. In trials in subjects with psoriatic arthritis, concomitant MTX use did not appear to influence the safety or efficacy of ustekinumab. In trials in subjects with Crohn's disease (CD-1 and CD-2) and ulcerative colitis (UC-1), 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, antagonists of IL-12 and IL-23, could normalize the formation of CYP450 enzymes. Upon initiation or discontinuation of PYZCHIVA 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 Available data from the Organization of Teratology Information Specialists (OTIS)/MotherToBaby Pregnancy Registry, published literature and pharmacovigilance in pregnant women have not identified a ustekinumab-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes ( see Data ). There are risks to the mother and the fetus associated with inflammatory bowel disease (IBD) in pregnancy. 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).
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 Disease-associated Maternal and Embryo/Fetal Risk Published data suggest that the risk of adverse pregnancy outcomes in women with IBD is associated with increased disease activity.
Adverse pregnancy outcomes include preterm delivery (before 37 weeks of gestation), low birth weight (less than 2500 g) infants, and small for gestational age at birth. Fetal/Neonatal Adverse Reactions Transport of endogenous IgG antibodies across the placenta increases as pregnancy progresses, and peaks during the third trimester. Therefore, ustekinumab products may be present in infants exposed in utero .
The potential clinical impact of ustekinumab product exposure in infants exposed in utero should be considered. Data Human Data An observational pregnancy registry conducted by (OTIS)/MotherToBaby in the U.S. and Canada (enrollment between 2013 and 2019) assessed the risk of major birth defects, pattern of major and minor anomalies in live-born infants, miscarriage, and adverse infant outcomes in women with ustekinumab exposure. In the registry study, there were 101 participants and 107 pregnancies with exposure to ustekinumab (88 prospective; 19 retrospective).
Most participants had a primary indication of CD (65.4%) or psoriasis (30.8%). The pregnancy registry did not identify a ustekinumab-associated risk of major birth defects, pattern of major or minor anomalies, increased risk of miscarriage or adverse infant outcomes. Methodological limitations of the registry include small sample size, lack of an internal comparison group, a mix of prospective and retrospective reports, and unmeasured confounders.
The conclusions from the pregnancy registry were consistent with the published literature and pharmacovigilance. 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 availa… [Excerpted — this section continues on DailyMed.]

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 Disease-associated Maternal and Embryo/Fetal Risk Published data suggest that the risk of adverse pregnancy outcomes in women with IBD is associated with increased disease activity.
Adverse pregnancy outcomes include preterm delivery (before 37 weeks of gestation), low birth weight (less than 2500 g) infants, and small for gestational age at birth. Fetal/Neonatal Adverse Reactions Transport of endogenous IgG antibodies across the placenta increases as pregnancy progresses, and peaks during the third trimester. Therefore, ustekinumab products may be present in infants exposed in utero .
The potential clinical impact of ustekinumab product exposure in infants exposed in utero should be considered. Data Human Data An observational pregnancy registry conducted by (OTIS)/MotherToBaby in the U.S. and Canada (enrollment between 2013 and 2019) assessed the risk of major birth defects, pattern of major and minor anomalies in live-born infants, miscarriage, and adverse infant outcomes in women with ustekinumab exposure. In the registry study, there were 101 participants and 107 pregnancies with exposure to ustekinumab (88 prospective; 19 retrospective).
Most participants had a primary indication of CD (65.4%) or psoriasis (30.8%). The pregnancy registry did not identify a ustekinumab-associated risk of major birth defects, pattern of major or minor anomalies, increased risk of miscarriage or adverse infant outcomes. Methodological limitations of the registry include small sample size, lack of an internal comparison group, a mix of prospective and retrospective reports, and unmeasured confounders.
The conclusions from the pregnancy registry were consistent with the published literature and pharmacovigilance. 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.
🧒 Pediatric Use ▾
8.4Pediatric Use Plaque Psoriasis The safety and effectiveness of PYZCHIVA have been established for the treatment of moderate to severe plaque psoriasis in pediatric patients 6 years of age and older who are candidates for phototherapy or systemic therapy. Use of PYZCHIVA in pediatric patients 12 to less than 17 years of age is supported by evidence from a multicenter, randomized, 60 week trial (Ps STUDY 3) of ustekinumab that included a 12 week, 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 PYZCHIVA 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 ), Clinical Pharmacology ( 12.3 )] . The safety and effectiveness of PYZCHIVA have not been established in pediatric patients less than 6 years of age with plaque psoriasis. Psoriatic Arthritis The safety and effectiveness of PYZCHIVA have been established for treatment of psoriatic arthritis in pediatric patients 6 years of age and older.
Use of PYZCHIVA in these age groups is supported by evidence from adequate and well controlled trials of ustekinumab in adult subjects 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 years of age and older 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 PYZCHIVA 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 PYZCHIVA 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.
🧬 Clinical Pharmacology ▾
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 trials in subjects with plaque psoriasis following subcutaneous administration.

This Medication Guide has been approved by the U.S. Food and Drug Administration. Revised: 02/2026 MEDICATION GUIDE PYZCHIVA ® (Piz-chi-va) (ustekinumab-ttwe) injection, for subcutaneous or intravenous use What is the most important information I should know about PYZCHIVA?
PYZCHIVA is a medicine that affects your immune system. PYZCHIVA can increase your risk of having serious side effects, including: Serious infections: PYZCHIVA may lower the ability of your immune system to fight infections and may increase your risk of infections. Some people have serious infections during treatment with 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 healthcare provider should check you for TB before starting PYZCHIVA. If your healthcare provider feels that you are at risk for TB, you may be treated with medicine for TB before you begin treatment with PYZCHIVA and during treatment with PYZCHIVA.
Your healthcare provider should watch you closely for signs and symptoms of TB while you are being treated with PYZCHIVA. You should not start PYZCHIVA if you have any kind of infection unless your healthcare provider says it is okay. Before starting PYZCHIVA, tell your healthcare provider 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 PYZCHIVA, call your healthcare provider 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. PYZCHIVA 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 PYZCHIVA may also be more likely to get these infections.
Cancers . PYZCHIVA may decrease the activity of your immune system and increase your risk for certain types of cancers. Tell your healthcare provider 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 PYZCHIVA, tell your healthcare provider if you develop any new skin growths. What is PYZCHIVA?
PYZCHIVA is a prescription medicine used to treat: adults and children 6 years of age and older with moderate to severe plaque 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 of age and older with active psoriatic arthritis. adults with moderately to severely active Crohn's disease. adults with moderately to severely active ulcerative colitis. It is not known if PYZCHIVA is safe and effective in children with Crohn's disease or ulcerative colitis or in children less than 6 years of age with plaque psoriasis or psoriatic arthritis.
Who should not use PYZCHIVA? Do not use PYZCHIVA if you are allergic to ustekinumab products or any of the ingredients in PYZCHIVA. See the end of this Medication Guide for a complete list of ingredients in PYZCHIVA.
Before you use or receive PYZCHIVA, tell your healthcare provider about all of your medical conditions, including if you: have any of the conditions or sympto… [Excerpted — this section continues on DailyMed.]

14 CLINICAL STUDIES
14.1Adult Subjects with 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 Adult Subjects with Plaque Psoriasis in Ps STUDY 1 and Ps STUDY 2 Ps STUDY 1 Ustekinumab Ps STUDY 2 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).

🧪 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.
