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)].

Interacciones de Ustekinumab

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 IMULDOSA 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.

Ustekinumab en el embarazo

Cita de la parte sobre embarazo (Pregnancy) de la etiqueta aprobada por la FDA. Se muestra en inglés. Pregunte a su médico antes de tomar cualquier medicamento si está embarazada o planea estarlo.

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.
