Ustekinumab-aekn 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 Ustekinumab-aekn 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 Ustekinumab-aekn after proper training in subcutaneous injection technique. Instruct patients to follow the directions provided in the Instructions for Use [see Instructions for Use]. Not made with natural rubber latex. 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, 1/2 inch needle is recommended. Prior to administration, visually inspect Ustekinumab-aekn for particulate matter and discoloration. Ustekinumab-aekn is a clear and colorless to slightly yellow solution and free of visible particles. Do not use Ustekinumab-aekn if it is discolored or cloudy, or if other particulate matter is present. Ustekinumab-aekn does not contain preservatives; therefore, discard any unused product remaining in the vial and/or syringe. 2.5 Preparation and Administration of Ustekinumab-aekn 130 mg/26 mL (5 mg/mL) Vial for Intravenous Infusion (Crohn’s Disease and Ulcerative Colit

WARNINGS AND PRECAUTIONS Infections: Serious infections have occurred. Avoid starting Ustekinumab-aekn during any clinically important active infection. If a serious infection or clinically significant infection develops, discontinue Ustekinumab-aekn until the infection resolves. ( 5.1 ) Theoretical Risk for Particular Infections : Serious infections from mycobacteria, salmonella, and Bacillus Calmette-Guerin (BCG) vaccinations have been reported in patients genetically deficient in IL-12/IL-23. Consider diagnostic tests for these infections as dictated by clinical circumstances. ( 5.2 ) Tuberculosis (TB): Evaluate patients for TB prior to initiating treatment with Ustekinumab-aekn. Initiate treatment of latent TB before administering Ustekinumab-aekn. ( 5.3 ) Malignancies: Ustekinumab products may increase risk of malignancy. The safety of ustekinumab products in patients with a history of or a known malignancy has not been evaluated. ( 5.4 ) Serious Hypersensitivity Reactions: If a severe or other clinically significant hypersensitivity reaction occurs discontinue Ustekinumab-aekn immediately and initiate appropriate medical treatment. ( 5.5 ) Posterior Reversible Encephalopathy Syndrome (PRES): If PRES is suspected, treat promptly, and discontinue Ustekinumab-aekn. ( 5.6 ) Immunizations: Avoid use of live vaccines in patients during treatment with Ustekinumab-aekn. ( 5.7 ) Noninfectious Pneumonia: Cases of interstitial pneumonia, eosinophilic pneumonia, and cryptogenic organizing pneumonia have been reported during post-approval use of ustekinumab products. If diagnosis is confirmed, discontinue Ustekinumab-aekn and institute appropriate treatment. ( 5.8 ) 5.1 Infections Ustekinumab products may increase the risk of infections and reactivation of latent infections. Serious bacterial, mycobacterial, fungal, and viral infections were observed in patients receiving ustekinumab products [see Adverse Reactions ( 6.1 , 6.3 )]. Serious infections requiring hospitalization, or otherwise clinically significant infections, reported in clinical trials included the following: Plaque Psoriasis: diverticulitis, cellulitis, pneumonia, appendicitis, cholecystitis, sepsis, osteomyelitis, viral infections, gastroenteritis, and urinary tract infections. Psoriatic arthritis: cholecystitis. Crohn’s disease: anal abscess, gastroenteritis, ophthalmic herpes zoster, pneumonia, and listeria meningitis. Ulcerative colitis: gastroenteritis, ophthalmic herpes zoster, pneumonia, and listeriosis. Avoid initiating treatment with Ustekinumab-aekn in patients with any clinically important active infection until the infection resolves or is adequately treated. Consider the risks and benefits of treatment prior to initiating use of Ustekinumab-aekn in patients with a chronic infection or a history of recurrent infection. Instruct patients to seek medical advice if signs or symptoms suggestive of an infection occur while on treatment with Ustekinumab-aekn and discontinue Ustekinumab-aekn for serious or clinically significant infections until the infection resolves or is adequately treated. 5.2 Theoretical Risk for Vulnerability to Particular Infections Individuals genetically deficient in IL-12/IL-23 are particularly vulnerable to disseminated infections from mycobacteria (including nontuberculous, environmental mycobacteria), salmonella (including nontyphi strains), and Bacillus Calmette-Guerin (BCG) vaccinations. Serious infections and fatal outcomes have been reported in such patients. It is not known whether patients with pharmacologic blockade of IL-12/IL-23 from treatment with ustekinumab products may be susceptible to these types of infections. Consider appropriate diagnostic testing, (e.g., tissue culture, stool culture, as dictated by clinical circumstances). 5.3 Pre-treatment Evaluation for Tuberculosis Evaluate patients for tuberculosis infection prior to initiating treatment with Ustekinumab-aekn. Avoid administering Ustekinumab-aekn to patients with active tuberculosis infection. Initiate treatment of latent tuberculosis prior to administering Ustekinumab-aekn. Consider anti-tuberculosis therapy prior to initiation of Ustekinumab-aekn in patients with a past history of latent or active tuberculosis in whom an adequate course of treatment cannot be confirmed. Closely monitor patients receiving Ustekinumab-aekn for signs and symptoms of active tuberculosis during and after treatment. 5.4 Malignancies Ustekinumab products are immunosuppressants and may increase the risk of malignancy. Malignancies were reported among subjects who received ustekinumab in clinical trials [see Adverse Reactions (6.1)]. In rodent models, inhibition of IL-12/IL-23p40 increased the risk of malignancy [see Nonclinical Toxicology ( 13 )]. The safety of ustekinumab products has not been evaluated in patients who have a history of malignancy or who have a known malignancy. There have been post-marketing reports of the rapid appearance of multiple cutaneous squamous cell carcinomas in patients receiving ustekinumab products who had pre-existing risk factors for developing non- melanoma skin cancer. Monitor all patients receiving Ustekinumab-aekn for the appearance of non-melanoma skin cancer. Closely follow patients greater than 60 years of age, those with a medical history of prolonged immunosuppressant therapy and those with a history of PUVA treatment [see Adverse Reactions ( 6.1 )]. 5.5 Serious Hypersensitivity Reactions Serious hypersensitivity reactions, including anaphylaxis and angioedema, have been reported with ustekinumab products in clinical trials and postmarketing. Some serious hypersensitivity reactions have occurred during the first intravenous dose of ustekinumab products [see Adverse Reactions ( 6.1 , 6.3 )]. If a severe or clinically significant hypersensitivity reaction occurs, discontinue Ustekinumab-aekn immediately and initiate appropriate medical treatment [see Contraindications ( 4 )] . 5.6 Posterior Reversible Encephalopathy Syndrome (PRES) Two cases of posterior reversible encephalopathy syndrome (PRES), also known as Reversible Posterior Leukoencephalopathy Syndrome (RPLS), were reported in clinical trials. Cases have also been reported in postmarketing experience in patients with psoriasis, psoriatic arthritis, and Crohn’s disease. Clinical presentation included headaches, seizures, confusion, visual disturbances, and imaging changes consistent with PRES a few days to several months after ustekinumab product initiation. A few cases reported latency of a year or longer. Patients recovered with supportive care following withdrawal of ustekinumab products. Monitor all patients treated with Ustekinumab-aekn for signs and symptoms of PRES. If PRES is suspected, promptly administer appropriate treatment and discontinue Ustekinumab-aekn. 5.7 Immunizations Prior to initiating therapy with Ustekinumab-aekn, patients should receive all age-appropriate immunizations as recommended by current immunization guidelines. Patients being treated with Ustekinumab-aekn should avoid receiving live vaccines. Avoid administering BCG vaccines during treatment with Ustekinumab-aekn or for one year prior to initiating treatment or one year following discontinuation of treatment. Caution is advised when administering live vaccines to household contacts of patients receiving Ustekinumab-aekn because of the potential risk for shedding from the household contact and transmission to patient. Non-live vaccinations received during a course of Ustekinumab-aekn may not elicit an immune response sufficient to prevent disease. 5.8 Noninfectious Pneumonia Cases of interstitial pneumonia, eosinophilic pneumonia, and cryptogenic organizing pneumonia have been reported during post-approval use of ustekinumab products. Clinical presentations included cough, dyspnea, and interstitial infiltrates following one to three doses. Serious outcomes have included respiratory failure and prolonged hospitalization. Patien

CONTRAINDICATIONS Ustekinumab-aekn is contraindicated in patients with clinically significant hypersensitivity to ustekinumab products or to any of the excipients in Ustekinumab-aekn [see Warnings and Precautions ( 5.5 )]. Clinically significant hypersensitivity to ustekinumab products or to any of the excipients in Ustekinumab-aekn. ( 4 )

12.1. Mechanism of Action 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. In in vitro models, ustekinumab products were shown to disrupt IL-12 and IL-23 mediated signaling and cytokine cascades by disrupting the interaction of these cytokines with a shared cell-surface receptor chain, IL-12Rβ1. The cytokines IL-12 and IL-23 have been implicated as important contributors to the chronic inflammation that is a hallmark of Crohn's disease and ulcerative colitis. In animal models of colitis, genetic absence or antibody blockade of the p40 subunit of IL-12 and IL-23, the target of ustekinumab products, was shown to be protective.
