How it works

From this product’s own US prescribing label.

Ustekinumab products are human IgG1қ 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.

  • General Considerations for Administration STEQEYMA is intended for use under the guidance and supervision of a healthcare provider.
  • STEQEYMA should only be administered to patients who will be closely monitored and have regular follow-up visits with a healthcare provider.
  • The appropriate dose should be determined by a healthcare provider using the patient's current weight at the time of dosing.
  • In pediatric patients, it is recommended that STEQEYMA be administered by a healthcare provider.
  • If a healthcare provider determines that it is appropriate, a patient may self-inject or a caregiver may inject STEQEYMA after proper training in subcutaneous injection technique.
  • Instruct patients to follow the directions provided in the Instructions for Use [see Instructions for Use].
  • It is recommended that each injection be administered at a different anatomic location (such as upper arms, gluteal regions, thighs, or any quadrant of abdomen) than the previous injection, and not into areas where the skin is tender, bruised, erythematous, or indurated.
  • When using the vial, a 1 mL syringe with a 27 gauge, ½ inch needle is recommended.
  • Prior to administration, visually inspect STEQEYMA for particulate matter and discoloration.
  • STEQEYMA is a clear to very slightly opalescent and colorless to pale yellow solution.
  • Do not use STEQEYMA if it is discolored or cloudy, or if other particulate matter is present.
  • STEQEYMA does not contain preservatives; therefore, discard any unused product remaining in the vial and/or syringe.
  • After withdrawing STEQEYMA from the single-dose vial for subcutaneous use, administer the dose immediately.
  • The vial does not contain preservatives.
  • Discard any unused portion of drug remaining in the vial or syringe. 2.5.
  • Preparation and Administration of STEQEYMA 130 mg/26 mL (5 mg/mL) Vial for Intravenous Infusion (Crohn's Disease and Ulcerative Colitis) STEQEYMA solution for intravenous infusion must be diluted, prepared, and infused by a healthcare professional using aseptic technique. 1.
  • Calculate the dose and the number of STEQEYMA vials needed based on patient weight (Table 4).
  • Each 26 mL vial of STEQEYMA contains 130 mg of ustekinumab-stba. 2.
  • Withdraw, and then discard a volume of the 0.9% Sodium Chloride Injection, USP from the 250 mL infusion bag equal to the volume of STEQEYMA to be added (discard 26 mL sodium chloride for each vial of STEQEYMA needed, for 2 vials- discard 52 mL, for 3 vials- discard 78 mL, 4 vials- discard 104 mL).
  • Alternatively, a 250 mL infusion bag containing 0.45% Sodium Chloride Injection, USP may be used. 3.
  • Withdraw 26 mL of STEQEYMA from each vial needed and add it to the 250 mL infusion bag.
  • The final volume in the infusion bag should be 250 mL.
  • Gently mix. 4.
  • Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
  • Do not use if visibly opaque particles, discoloration or foreign particles are observed. 5.
  • Infuse the diluted solution over a period of at least one hour.
  • Once diluted, the infusion should be completely administered within four hours of the dilution in the infusion bag. 6.
  • Use only an infusion set with an in-line, sterile, non-pyrogenic, low protein-binding filter (pore size 0.2 micrometer). 7.
  • Do not infuse STEQEYMA concomitantly in the same intravenous line with other agents. 8.
  • STEQEYMA does not contain preservatives.
  • Each vial is for a one-time use in only one patient.
  • Discard any remaining solution.
  • Dispose any unused medicinal product in accordance with local requirements.
  • Storage If necessary, the diluted infusion solution may be kept at room temperature up to 30°C (86°F) for up to 3 hours.
  • Storage time at room temperature begins once the diluted solution has been prepared.
  • The infusion should be completed within 4 hours after the dilution in the infusion bag (cumulative time after preparation including the storage and the infusion period).
  • Do not freeze.
  • Discard any unused portion of the infusion solution.

Pregnancy and breastfeeding

  • 8.1.
  • Pregnancy 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.

  • Use of STEQEYMA 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 STEQEYMA 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 STEQEYMA have not been established in pediatric patients less than 6 years of age with plaque psoriasis.
  • Psoriatic Arthritis The safety and effectiveness of STEQEYMA have been established for treatment of psoriatic arthritis in pediatric patients 6 years of age and older.
  • Use of STEQEYMA 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 STEQEYMA have not been established in pediatric patients less than 6 years old with psoriatic arthritis.

Other medicines

  • 7.
  • DRUG INTERACTIONS 7.1.
  • Concomitant 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. 7.2.
  • CYP450 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 STEQEYMA 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) ] . 7.3.
  • Allergen 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.

  • Immunogenicity 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 ustekinumab or of other ustekinumab products.
  • Approximately 6 to 12.4% of subjects treated with ustekinumab in clinical trials in subjects with plaque psoriasis and psoriatic arthritis developed antibodies to ustekinumab, which were generally low-titer.
  • In clinical trials in subjects with plaque psoriasis, antibodies to ustekinumab were associated with reduced or undetectable serum ustekinumab concentrations and reduced efficacy.
  • In trials in subjects with plaque psoriasis, the majority of subjects who were positive for antibodies to ustekinumab had neutralizing antibodies.
  • In clinical trials in subjects with Crohn's disease and ulcerative colitis, 2.9% and 4.6% of subjects, respectively, developed antibodies to ustekinumab when treated with ustekinumab for approximately one year.
  • No apparent association between the development of antibodies to ustekinumab and the development of injection site reactions was seen. 6.3.
  • Postmarketing Experience The following adverse reactions have been reported during post-approval use of ustekinumab products.
  • Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to ustekinumab product exposure.
