In pediatric patients 12 years of age and older, administer SPEVIGO under the supervision of an adult. If a patient experiences a GPP flare while receiving subcutaneous SPEVIGO, the GPP flare may be treated with intravenous SPEVIGO [see Dosage and Administration (2.4) ] . Intravenous Use for Treatment of GPP Flare SPEVIGO vials are for intravenous use for treatment of...

Side Effects (Adverse Reactions)

6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the labeling: Infections [see Warnings and Precautions (5.1) ] Hypersensitivity and Infusion-Related Reactions [see Warnings and Precautions (5.3) ] Treatment of GPP When Not Experiencing a Flare: SPEVIGO has been associated with an increased incidence (≥9 cases per 100 patient-years) of injection site reaction, urinary tract infection, arthralgia, and pruritus. ( 6.1 ) Treatment of GPP Flare: The most common adverse reactions (≥5%) are asthenia and fatigue, headache, nausea, pruritus and prurigo, infusion site hematoma and bruising, and urinary tract infection. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact LEO Pharma, Inc. at 1-877-494-4536 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical 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 clinical practice. Adverse Reactions with Intravenous SPEVIGO for Treatment of GPP Flare (Study Effisayil-1) SPEVIGO was studied in Study Effisayil-1, a randomized, double-blind, placebo-controlled study comparing a single intravenous 900 mg dose of SPEVIGO (n=35) with placebo (n=18) in subjects with generalized pustular psoriasis (GPP) flare. Subjects in either treatment group who continued to experience flare symptoms at Week 1 were eligible to receive a single open-label intravenous dose of 900 mg of SPEVIGO (second dose and first dose for subjects in the SPEVIGO and placebo groups, respectively). At Week 1, 12 (34%) subjects and 15 subjects (83%) in the SPEVIGO and placebo groups, respectively, received open-label SPEVIGO. After Week 1 to Week 12, subjects in either treatment group whose GPP flare reoccurred after achieving a clinical response were eligible to receive a single open-label rescue intravenous dose of 900 mg of SPEVIGO, with a maximum of 3 total doses of SPEVIGO throughout the study. Six subjects received a single open-label rescue dose of SPEVIGO. Thirty-six subjects received 1 dose of SPEVIGO, 13 subjects received 2 doses of SPEVIGO, and 2 subjects received 3 doses of SPEVIGO throughout the study [see Clinical Studies (14) ] . Subjects ranged in age from 21 to 69 years (mean age of 43 years); 45% were White and 55% were Asian; and 68% were female. Table 1 summarizes selected adverse reactions that occurred at a rate of at least 1% and at a higher rate in the intravenous SPEVIGO group than in the placebo group through Week 1. Table 1 Selected Adverse Reactions Occurring in ≥1% of the Intravenous SPEVIGO Group and More Frequently than in the Placebo Group through Week 1 in Subjects with GPP Flare (Study Effisayil-1) Adverse Reaction Intravenous SPEVIGO N = 35 n (%) Placebo N = 18 n (%) Asthenia and Fatigue 3 (9) 1 (6) Headache 3 (9) 1 (6) Nausea 2 (6) 0 Pruritus and prurigo 2 (6) 0 Infusion site hematoma and bruising 2 (6) 0 Urinary tract infection 2 (6) 0 Bacteremia 1 (3) 0 Bacteriuria 1 (3) 0 Cellulitis 1 (3) 0 Herpes dermatitis and oral herpes 1 (3) 0 Upper respiratory tract infection 1 (3) 0 Dyspnea 1 (3) 0 Eye edema 1 (3) 0 Urticaria 1 (3) 0 Specific Adverse Reactions Infections The most frequent adverse reactions that occurred in subjects treated with intravenous SPEVIGO were infections. During the 1-week placebo-controlled period in Study Effisayil-1, infections were reported in 14% of subjects treated with SPEVIGO compared with 6% of subjects treated with placebo. Serious infection (urinary tract infection) was reported in 1 subject (3%) treated with SPEVIGO and no subjects treated with placebo. Infections observed through Week 1 in Study Effisayil-1 in subjects treated with SPEVIGO were mild (29%) to moderate (71%). Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) Two cases of DRESS were reported in Study...

Contraindications

4 CONTRAINDICATIONS SPEVIGO is contraindicated in patients with severe or life-threatening hypersensitivity to spesolimab-sbzo or to any of the excipients in SPEVIGO. Reported hypersensitivity reactions have included drug reaction with eosinophilia and systemic symptoms (DRESS) and anaphylaxis [see Warnings and Precautions (5.3) and Adverse Reactions (6) ] . Severe or life-threatening hypersensitivity to spesolimab-sbzo or to any of the excipients in SPEVIGO ( 4 )

Pregnancy and Breastfeeding

8.1 Pregnancy Risk Summary The limited data on the use of SPEVIGO in pregnant women are insufficient to inform a drug-associated risk of adverse pregnancy-related outcomes. Human IgG is known to cross the placental barrier; therefore, SPEVIGO may be transmitted from the mother to the developing fetus. In an animal reproduction study, intravenous administration of a surrogate antibody against IL36R in mice during the period of organogenesis did not elicit any reproductive toxicity (see Data ) . The background risk of major birth defects and miscarriage for the indicated population is 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 in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data Embryo-fetal development and pre- and postnatal development toxicity studies were performed in mice using a surrogate mouse specific IL36R antagonist monoclonal antibody. In the embryo-fetal development study, the surrogate was administered intravenously at doses up to 50 mg/kg to pregnant female mice twice weekly during the period of organogenesis. The surrogate was not associated with embryo-fetal lethality or fetal malformations. In the pre- and postnatal development toxicity study, the surrogate was administered intravenously at doses up to 50 mg/kg to pregnant female mice twice weekly from gestation day 6 through lactation day 18. There were no maternal effects observed. There were no treatment-related effects observed on postnatal developmental, neurobehavioral, or reproductive performance of offspring.
