Risankizumab

12.1 Mechanism of Action Risankizumab-rzaa is a humanized IgG1 monoclonal antibody that selectively binds to the p19 subunit of human IL-23 cytokine and inhibits its interaction with the IL-23 receptor. IL-23 is a naturally occurring cytokine that is involved in inflammatory and immune responses. Risankizumab-rzaa inhibits the release of pro-inflammatory cytokines and chemokines.

( 2.7 ) 2.1 Procedures Prior to Treatment Initiation For the treatment of Crohn’s disease and ulcerative colitis, obtain liver enzymes and bilirubin levels prior to initiating treatment with SKYRIZI [see Warnings and Precautions ( 5.4 )] Evaluate patients for tuberculosis (TB) infection prior to initiating treatment with SKYRIZI [see Warnings and Precautions ( 5.3 )] . Complete all age-appropriate vaccinations as recommended by current immunization guidelines [see Warnings and Precautions ( 5.5 )]. 2.2 General Considerations for Administration • Visually inspect SKYRIZI for particulate matter and discoloration prior to administration. The solution may contain a few translucent to white particles. ○ SKYRIZI 150 mg/mL prefilled pen or prefilled syringe, 180 mg/1.2 mL prefilled syringe or prefilled cartridge, and 360 mg/2.4 mL prefilled cartridge: a colorless to yellow, and clear to slightly opalescent solution. ○ SKYRIZI 90 mg/mL prefilled syringe and 600 mg/10 mL vial: a colorless to slightly yellow, and clear to slightly opalescent solution. ○ Do not use if the solution contains large particles or is cloudy or discolored. • Discard after use. Do not reuse. 2. 3 Recommended Dosage for Plaque Psoriasis The recommended dosage is 150 mg administered by subcutaneous injection at Week 0, Week 4, and every 12 weeks thereafter. 2. 4 Recommended Dosage for Psoriatic Arthritis The recommended dosage is 150 mg administered by subcutaneous injection at Week 0, Week 4, and every 12 weeks thereafter. SKYRIZI may be administered alone or in combination with non-biologic disease-modifying antirheumatic drugs (DMARDs). 2. 5 Preparation and Administration Instruction s (Plaque Psoriasis and Psoriatic Arthritis) Administer SKYRIZI 150 mg/mL prefilled pen or prefilled syringe subcutaneously. Patients may self-inject SKYRIZI after training in subcutaneous injection technique. Provide proper training to patients and/or caregivers on the subcutaneous injection technique of SKYRIZI. Before injecting, remove the carton with SKYRIZI from the refrigerator and without removing the prefilled pen or prefilled syringe from the carton, allow SKYRIZI to reach room temperature out of direct sunlight (30 to 90 minutes for the prefilled pen and 15 to 30 minutes for the prefilled syringe). Do not inject into areas where the skin is tender, bruised, erythematous, indurated or affected by psoriasis. Administration of SKYRIZI in the upper, outer arm may only be performed by a healthcare professional or caregiver. If a dose is missed, administer the dose as soon as possible. Thereafter, resume dosing at the regular scheduled time. The SKYRIZI “Instructions for Use” contains more detailed instructions on the preparation and administration of SKYRIZI [see Instructions for Use ]. Instruct the patient to read the Instructions for Use before administration. 2.6 Recommended Dosage for Crohn’s Disease Adult Patients: Induction The recommended induction dosage of SKYRIZI is 600 mg administered by intravenous infusion over a period of at least one hour at Week 0, Week 4, and Week 8. Adult Patients: Maintenance The recommended maintenance dosage of SKYRIZI is 180 mg or 360 mg administered by subcutaneous injection at Week 12, and every 8 weeks thereafter. Use the lowest effective dosage needed to maintain therapeutic response. 2.7 Recommended Dosage for Ulcerative Colitis Adult Patients: Induction The recommended induction dosage of SKYRIZI is 1,200 mg administered by intravenous infusion over a period of at least two hours at Week 0, Week 4, and Week 8. Adult Patients: Maintenance The recommended maintenance dosage of SKYRIZI is 180

Plaque Psoriasis A total of 2234 subjects were treated with SKYRIZI in clinical development trials in plaque psoriasis. Of these, 1208 subjects with psoriasis were exposed to SKYRIZI for at least one year. Data from placebo- and active-controlled trials were pooled to evaluate the safety of SKYRIZI for up to 16 weeks. In total, 1306 subjects were evaluated in the SKYRIZI 150 mg group. Table 2 summarizes the adverse drug reactions that occurred at a rate of at least 1% and at a higher rate in the SKYRIZI group than the placebo group during the 16-week controlled period of pooled clinical trials. Table 2. Adverse Drug Reactions Occurring in ≥ 1% of Subjects with Plaque Psoriasis on SKYRIZI through Week 16 Adverse Drug Reactions SKYRIZI N = 1306 n (%) Placebo N = 300 n (%) Upper respiratory infections a 170 (13.0) 29 (9.7) Headache b 46 (3.5) 6 (2.0) Fatigue c 33 (2.5) 3 (1.0) Injection site reactions d 19 (1.5) 3 (1.0) Tinea infections e 15 (1.1) 1 (0.3) a Includes: respiratory tract infection (viral, bacterial or unspecified), sinusitis (including acute), rhinitis, nasopharyngitis, pharyngitis (including viral), tonsillitis b Includes: headache, tension headache, sinus headache, cervicogenic headache c Includes: fatigue, asthenia d Includes: injection site bruising, erythema, extravasation, hematoma, hemorrhage, infection, inflammation, irritation, pain, pruritus, reaction, swelling, warmth e Includes: tinea pedis, tinea cruris, body tinea, tinea versicolor, tinea manuum, tinea infection, onychomycosis Adverse drug reactions that occurred in < 1% but > 0.1% of subjects in the SKYRIZI group and at a higher rate than in the placebo group through Week 16 were folliculitis and urticaria. Specific Adverse Drug Reactions Infections In the first 16 weeks, infections occurred in 22.1% of the SKYRIZI group (90.8 events per 100 subject-years) compared with 14.7% of the placebo group (56.5 events per 100 subject-years) and did not lead to discontinuation of SKYRIZI. The rates of serious infections for the SKYRIZI group and the placebo group were ≤0.4%. Serious infections in the SKYRIZI group included cellulitis, osteomyelitis, sepsis, and herpes zoster. In Studies PsO-1 and PsO-2, through Week 52, the rate of infections (73.9 events per 100 subject-years) was similar to the rate observed during the first 16 weeks of treatment. Safety T hrough Week 52 Through Week 52, no new adverse reactions were identified, and the rates of the adverse reactions were similar to those observed during the first 16 weeks of treatment. During this period, serious infections that led to study discontinuation included pneumonia. Psoriatic Arthritis The overall safety profile observed in subjects with psoriatic arthritis treated with SKYRIZI is generally consistent with the safety profile in subjects with plaque psoriasis. Additionally, in the Phase 3 placebo-controlled trials the incidence of hepatic events was higher in the SKYRIZI group (5.4%, 16.7 events per 100 patient years) compared to the placebo group (3.9%, 12.6 events per 100 patient years). Of these, the most common events that were reported more frequently in both the placebo group and the SKYRIZI group were ALT increased (placebo: n=12 (1.7%); SKYRIZI: n=16 (2.3%)), AST increased (placebo: n=9 (1.3%); SKYRIZI: n=13 (1.8%)), and GGT increased (placebo: n=5 (0.7%); SKYRIZI: n=8 (1.1%)). There were no serious hepatic events reported. The incidence of hypersensitivity reactions was higher in the SKYRIZI group (n=16, 2.3%) compared to the placebo group (n=9, 1.3%). In the Phase 3 placebo-controlled trials, hypersensitivity reactions report
