( 2.2 ) Administer ICOTYDE on an empty stomach with water upon waking. ( 2.2 ) Wait at least 30 minutes after taking ICOTYDE before eating food. ( 2.2 ) For patients who have difficulty swallowing tablets, ICOTYDE can be dispersed in water. ( 2.3 ) 2.1 Recommended Evaluation and Immunizations Prior to Treatment Initiation Consider evaluating patients for tuberculosis (TB) infection prior to initiating treatment with ICOTYDE based on clinical judgment [see Warnings and Precautions (5.2) ] . Complete all age-appropriate vaccinations according to current immunization guidelines [see Warnings and Precautions (5.3) ] . 2.2 Recommended Dosage and Administration Instructions The recommended dosage of ICOTYDE is 200 mg administered orally once daily. Administer ICOTYDE upon waking on an empty stomach with water. Wait at least 30 minutes after taking ICOTYDE before eating food. Swallow ICOTYDE whole. Do not crush, split, or chew tablets [see Clinical Pharmacology (12.3) ] . If a patient misses a dose, instruct patients to take the missed dose as soon as possible with a return to normal dosing schedule the following day. 2.3 Alternative Preparation and Administration Instructions for Patients Who Have Difficulty Swallowing Tablets ICOTYDE 200 mg tablet can also be dispersed in water using the following instructions: Place one ICOTYDE tablet in a cup containing at least 120 mL (4 ounces) of water. It may take a few minutes for the tablet to disperse. The tablet may not completely disperse. The mixture may look yellow, milky, or cloudy, and small pieces may be seen in the water which are safe to swallow. Gently swirl the cup before drinking and swallowing the full mixture. Add at least 120 mL (4 ounces) of additional water to the cup and completely swallow the contents to make sure the whole dose is taken. Complete administration of ICOTYDE within 15 minutes of dispersion in water.

5 WARNINGS AND PRECAUTIONS Infections : Avoid treatment with ICOTYDE in patients with any clinically important active infection until the infection resolves or is adequately treated. If such an infection develops, discontinue ICOTYDE until the infection resolves. ( 5.1 ) Tuberculosis (TB) : Consider evaluating for TB prior to initiating treatment with ICOTYDE based on clinical judgment. Monitor patients for signs and symptoms of active TB during and after treatment with ICOTYDE. ( 5.2 ) Immunizations : Avoid use of live vaccines during treatment with ICOTYDE. ( 5.3 ) 5.1 Infections Medicines that interact with the immune system may increase the risk of infection. In the 16-week placebo-controlled trials in subjects with moderate-to-severe plaque psoriasis, the rate of serious infections for ICOTYDE-treated subjects was 0.2% compared to 0.4% of subjects who received placebo. Avoid treatment with ICOTYDE in patients with any clinically important active infection until the infection resolves or is adequately treated. In patients with a chronic infection or a history of recurrent infection, consider the risks and benefits prior to prescribing ICOTYDE. Instruct patients to seek medical advice if signs or symptoms of clinically important infection occur. If a patient develops such an infection and/or is not responding to standard therapy, monitor the patient closely and discontinue ICOTYDE until the infection resolves. 5.2 Tuberculosis Consider evaluating patients for tuberculosis (TB) infection prior to initiating treatment with ICOTYDE based on clinical judgment. Consider anti-TB therapy prior to initiating ICOTYDE in patients with a past history of latent or active TB in whom an adequate course of treatment cannot be confirmed. Monitor patients for signs and symptoms of active TB during and after ICOTYDE treatment. Avoid administering ICOTYDE to patients with active TB. 5.3 Immunizations Avoid use of live vaccines in patients during treatment with ICOTYDE. Medications that interact with the immune system may increase the risk of infection following administration of live vaccines. Prior to initiating therapy with ICOTYDE, complete immunizations according to current immunization guidelines. No data are available on the response to live or inactive vaccines.

8.1 Pregnancy Risk Summary The available data on the use of ICOTYDE during pregnancy are insufficient to evaluate for a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. In an animal reproduction study in rabbits, oral administration of icotrokinra to pregnant rabbits during the period of organogenesis at a dose 157 times the maximum recommended human dose (MRHD) based on AUC comparison resulted in maternal body weight loss, low food consumption, late pregnancy loss, and an increased fetal incidence of fused ribs (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 defects, loss, and 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. There is a pregnancy safety study for ICOTYDE. If a patient becomes pregnant while receiving ICOTYDE, healthcare providers can report ICOTYDE exposure by calling 1-800-526-7736 or visiting www.ICOTYDE.com. Data Animal Data In an embryo-fetal development study, icotrokinra was administered to pregnant rats during the period of organogenesis at oral doses of 70, 200, and 1000 mg/kg/day. No maternal or embryo-fetal toxicity was observed at doses up to 1000 mg/kg/day (297 times the MRHD based on AUC comparison). In another embryo-fetal development study, icotrokinra was administered to pregnant rabbits during the period of organogenesis at oral doses of 50, 200, and 500 mg/kg/day. Maternal body weight loss, low food consumption, late pregnancy loss, and an increased fetal incidence of fused ribs were observed at 500 mg/kg/day (157 times the MRHD based on AUC comparison). No maternal or embryo-fetal toxicity was noted at doses up to 200 mg/kg/day in rabbits (27 times the MRHD based on AUC comparison). In a pre- and post-natal development study in rats, icotrokinra was administered to pregnant rats during pregnancy and lactation periods at oral doses of 20, 70, and 200 mg/kg/day. No maternal or developmental toxicity was noted in doses up to 200 mg/kg/day (127 times the MRHD based on AUC comparison).

6 ADVERSE REACTIONS Most common adverse reactions (≥1%) are headache, nausea, cough, fungal infection, and fatigue. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Janssen Biotech, Inc. at 1-800-526-7736 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 practice. The safety of ICOTYDE was evaluated in two placebo-controlled trials (Trial PSO-3 and Trial PSO-4) and two placebo- and active-controlled trials (Trial PSO-1 and Trial PSO-2) [see Clinical Studies (14) ] . A total of 2367 adults and pediatric subjects 12 years of age and older who weigh at least 40 kg with moderate-to-severe plaque psoriasis received ICOTYDE 200 mg orally once daily. Of these, 648 subjects were treated with ICOTYDE for at least one year. Data from these four trials were pooled to evaluate the safety of ICOTYDE compared to placebo for 16 weeks. Adverse Reactions Weeks 0 to 16 Table 1: Adverse Reactions that Occurred in ≥1% of Subjects in the ICOTYDE Group and More Frequently than in the Placebo Group in Trials PSO-1, PSO-2, PSO-3, and PSO-4 through Week 16 percentages based on Cochran-Mantel-Haenszel (CMH) adjusted proportions. Adverse Reactions ICOTYDE N=1296 n (%) Placebo N=568 n (%) Headache 51 (4.1) 19 (3.3) Nausea 15 (1.2) 3 (0.5) Cough 15 (1.2) 1 (0.2) Fungal Infection Fungal infection includes tinea pedis (n=4), tinea versicolor (n=2), oral candidiasis (n=2), onychomycosis (n=1), skin candida (n=1), urinary tract candidiasis (n=1), vulvovaginal candidiasis (n=1), fungal skin infection (n=1), genital infection fungal (n=1), ear infection fungal (n=1), laryngitis fungal (n=1). Two subjects experienced more than 1 event. 14 (1.1) 0 (0) Fatigue 15 (1.0) 3 (0.5) Adverse reactions that occurred in < 1% of subjects in the ICOTYDE group and at a higher rate than in the placebo group through Week 16 in Trials PSO-1, PSO-2, PSO-3, and PSO-4 were: gastritis, abdominal discomfort, and one fatal case involving upper gastrointestinal bleeding in a subject with underlying risk factors. A relationship of this event to ICOTYDE is not established. Adverse Reactions in Pediatric Subjects 12 Years of Age and Older The safety of ICOTYDE was evaluated in pediatric subjects 12 years of age and older who weigh at least 40 kg with moderate-to-severe plaque psoriasis in two placebo-controlled trials (Trial PSO-3 and Trial PSO-4). A total of 72 pediatric subjects were treated with ICOTYDE 200 mg orally once daily. Of these, 45 subjects were treated with ICOTYDE for at least one year. The adverse reactions observed in pediatric subjects were consistent with the most common adverse reactions (≥ 1%) observed in the overall population.
