IMULDOSA 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 IMULDOSA 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 IMULDOSA after proper training in subcutaneous injection technique. Instruct patients to follow the directions provided in the Instructions for Use [see Instructions for Use ]. 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 single-dose vial, a 1 mL syringe with a 27 gauge, ½ inch needle is recommended. Prior to administration, visually inspect IMULDOSA for particulate matter and discoloration IMULDOSA is a clear to slightly opalescent and colorless to slightly yellow solution. Do not use IMULDOSA if it is discolored or cloudy, or if other particulate matter is present. IMULDOSA does not contain preservatives; therefore, discard any unused product remaining in the vial and/or syringe. 2.6 Preparation and Administration of IMULDOSA 130 mg/26 mL (5 mg/mL) Vial for Intravenous Infusion (Crohn’s Disease and Ulcerative Colitis) IMULDOSA solution for intravenous infusion must be diluted, prepared and infused by a healthcare professional using aseptic technique. Calculate the dose and the number of IMULDOSA vials needed based on patient weight (Table 3 and Table 4). Each 26 mL vial of IMULDOSA contains 130 mg of ustekinumab-srlf. Withdraw, and then discard a volume of the 0.9% Sodium Chloride Injection, USP from the 250 mL infusion bag equal to the volume of IMULDOSA to be added (discard 26 mL sodium chloride for each vial of IMULDOSA needed, for 2 vials- discard 52 mL, for 3 vials- discard 78 mL, 4 vials- discard 104 mL). Alternatively, a 250 mL infusion bag containing 0.45% Sodium Chloride Injection, USP may be used. Infusion bags must be made of either polypropylene (PP) or polyethylene (PE). Withdraw 26 mL of IMULDOSA from each vial needed and add it to the 250 mL infusion bag. The final volume in the infusion bag should be 250 mL. Gently mix. Visually inspect the diluted solution before infusion. Do not use if visibly opaque particles, discoloration or foreign particles are observed. Infuse the diluted solution over a period of at least one hour. Once diluted, the infusion should be completely administered within eight hours of the dilution in the infusion bag. Use only an infusion set with an in-line, sterile, non-pyrogenic, low protein-binding filter (pore size 0.2 micrometer). Do not infuse IMULDOSA concomitantly in the same intravenous line with other agents. IMULDOSA does not contain preservatives. Each vial is for one-time use in only one patient. Discard any remaining solution. Dispose any unused medicinal product in accordance with local requirements. Storage If necessary, the diluted infusion solution may be kept at room temperature up to 25°C (77°F) for up to 7 hours. Storage time at room temperature begins once the diluted solution has been prepared. The infusion should be completed within 8 hours after the dilution in the infusion bag (cumulative time after preparation including the storage and the infusion period). Do not freeze. Discard any unused portion of the infusion solution.

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 )]. Infections In the placebo-controlled period of clinical trials of subjects with plaque psoriasis (average follow-up of 12.6 weeks for subjects receiving placebo and 13.4 weeks for Ustekinumab-treated subjects), 27% of Ustekinumab-treated subjects reported infections (1.39 per patient-years of follow-up) compared with 24% of subjects receiving placebo (1.21 per patient-years of follow-up). Serious infections occurred in 0.3% of ustekinumab-treated subjects (0.01 per patient-years of follow-up) and in 0.4% of subjects receiving placebo (0.02 per patient-years of follow-up) [ see Warnings and Precautions ( 5.1 )]. In the controlled and non-controlled portions of clinical trials in subjects with plaque psoriasis (median follow-up of 3.2 years), representing 8998 patient-years of exposure, 72.3% of Ustekinumab- treated subjects reported infections (0.87 per patient-years of follow-up). Serious infections were reported in 2.8% of subjects (0.01 per patient-years of follow-up). Malignancies In the controlled and non-controlled portions of clinical trials in subjects with plaque psoriasis (median follow-up of 3.2 years, representing 8998 patient-years of exposure), 1.7% of ustekinumab-treated subjects reported malignancies excluding non-melanoma skin cancers (0.60 per hundred patient-years of follow-up). Non-melanoma skin cancer was reported in 1.5% of ustekinumab-treated subjects (0.52 per hundred patient-years of follow-up) [ see Warnings and Precautions ( 5.4 )]. The most frequently observed malignancies other than non-melanoma skin cancer during the clinical trials were: prostate, melanoma, colorectal and breast. Malignancies other than non-melanoma skin cancer in ustekinumab-treated subjects during the controlled and uncontrolled portions of trials were similar in type and number to what would be expected in the general U.S. population according to the SEER database (adjusted for age, gender and race). 1 Pediatric Subjects with Plaque Psoriasis The safety of ustekinumab was assessed in two trials of pediatric subjects with moderate to severe plaque psoriasis. Ps STUDY 3 evaluated safety for up to 60 weeks in 110 pediatric subjects 12 to 17 years old. Ps STUDY 4 evaluated safety for up to 56 weeks in 44 pediatric subjects 6 to 11 years old. The safety profile in pediatric subjects was similar to the safety profile from trials in adults with plaque psoriasis. Psoriatic Arthritis The safety of ustekinumab was assessed in 927 subjects in two randomized, double- blind, placebo-controlled trials in adults with active psoriatic arthritis (PsA). The overall safety profile of ustekinumab in subjects with PsA was consistent with the safety profile seen in clinical trials in adult subjects with plaque psoriasis . A higher incidence of arthralgia, nausea, and dental infections was observed in ustekinumab-treated subjects when compared with placebo-treated subjects (3% vs. 1% for arthralgia and 3% vs. 1% for nausea; 1% vs. 0.6% for dental infections) in the placebo- controlled portions of the PsA clinical trials. Adult Subjects with Crohn’s Disease The safety of ustekinumab was assessed in 1407 subjects with moderately to severely active Crohn’s disease (Crohn’s Disease Activity Index [CDAI] greater than or equal to 220 and less than or equal to 450) in three randomized, double- blind, placebo-controlled, parallel-group, multicenter trials. These 1407 subjects included 40 subjects who received a prior investigational intravenous ustekinumab formulation but were not included in the efficacy analyses. In trials CD-1 and CD-2 there were 470 subjects who received ustekinumab 6 mg/kg as a weight-based single intravenous induction dose and 466 who received placebo [ see Dosage and Administration ( 2.3 )]. Subjects who were responders in either trial CD-1 or CD-2 were randomized to receive a subcutaneous maintenance regimen of either 90 mg ustekinumab every 8 weeks, or placebo for 44 weeks in trial CD-3. Subjects in these 3 trials may have received other concomitant therapies including aminosalicylates, immunomodulatory agents [azathioprine (AZA), 6-mercaptopurine (6-MP), methotrexate (MTX)], oral corticosteroids (prednisone or budesonide), and/or antibiotics for their Crohn’s disease [ see Clinical Studies ( 14.4 ) ]. The overall safety profile of ustekinumab was consistent with the safety profile seen in the clinical trials in adult subjects with plaque psoriasis and psoriatic arthritis. Common adverse reactions in trials CD-1 and CD-2 and in trial CD-3 are listed in Tables 5 and 6, respectively. Table 6:Common adverse reactions through Week 8 in trials CD-1 and CD-2 occurring in ≥3% of ustekinumab-treated subjects and higher than subjects receiving placebo Placebo N=466 Ustekinumab 6 mg/kg single intravenous induction dose N=470 Vomiting 3% 4% Other less common adverse reactions reported in subjects in trials CD-1 and CD-2 included asthenia (1% vs 0.4%), acne (1% vs 0.4%), and pruritus (2% vs 0.4%). Table 6: Common adverse reactions through Week 44 in trial CD-3 occurring in ≥3% of ustekinumab-treated subjects and higher than subjects receiving placebo Placebo N=133 Ustekinumab 90 mg subcutaneous maintenance dose every 8 weeks N=131 Nasopharyngitis 8% 11% Injection site erythema 0 5% Vulvovaginal candidiasis/mycotic infection 1% 5% Bronchitis 3% 5% Pruritus 2% 4% Urinary tract infection 2% 4% Sinusitis 2% 3% Infections In subjects with Crohn’s disease, serious or other clinically significant infections included anal abscess, gastroenteritis, and pneumonia. In addition, listeria meningitis and ophthalmic herpes zoster were reported in one subject each [see Warnings and Precautions ( 5.1 )]. Malignancies With up to one year of treatment in the Crohn’s disease clinical trials, 0.2% of ustekinumab-treated subjects (0.36 events per hundred patient-years) and 0.2% of placebo-treated subjects (0.58 events per hundred patient-years) developed non- melanoma skin cancer. Malignancies other than non-melanoma skin cancers occurred in 0.2% of ustekinumab-treated subjects (0.27 events per hundred patient- years) and in none of the placebo-treated subjects. Hypersensitivity Reactions Including Anaphylaxis In CD trials, two subjects reported hypersensitivity reactions following ustekinumab administration. One subject experienced signs and symptoms consistent with anaphylaxis (tightness of the throat, shortness of breath, and flushing) after a single subcutaneous administration (0.1% of subjects receiving subcutaneous ustekinumab). In addition, one subject experienced signs and symptoms consistent with or related to a hypersensitivity reaction (chest discomfort, flushing, urticaria, and increased body temperature) after the initial intravenous ustekinumab dose (0.08% of subjects receiving intravenous ustekinumab). These subjects were treated with oral antihistamines or corticosteroids and in both cases symptoms resolved within an hour [see Warnings and Precautions ( 5.5 )]. Ulcerative Colitis The safety of ustekinumab was evaluated in two randomized, double-blind, placebo- controlled clinical trials (UC-1 [IV induction] and UC-2 [SC maintenance]) in 960 adult subjects with moderately to severely active ulcerative colitis [ see Clinical Studies ( 14.5 ) ]. The overall safety profile of ustekinumab in subjects with ulcerative colitis was consistent with the safety profile seen across all approved indications. Adverse reactions reported in at least 3% of ustekinumab-treated subjects and at a higher rate than placebo were: • Induction (UC-1): nasopharyngitis (7% vs 4%). • Maintenance (UC-2): nasopharyngitis (24% vs 20%), headache (10% vs 4%), abdominal pain (7% vs 3%), influenza (6% vs 5%), fever (5% vs. 4%), diarrhea (4% vs 1%), sinusitis (4% vs 1%), fatigue (4% vs 2%), and nausea (3% vs 2%). Infections In subjects with ulcerative colitis, serious or other clinically significant infections included gastroenteritis and pneumonia. In addition, listeriosis and ophthalmic herpes zoster were reported in one subject each [ see Warnings and Precautions ( 5.1 ) ]. Malignancies With up to one year of treatment in the ulcerative colitis clinical trials, 0.4% of ustekinumab-treated subjects (0.48 events per hundred patient-years) and 0.0% of subjects receiving placebo (0.00 events per hundred patient-years) developed non-melanoma skin cancer. Malignancies other than non-melanoma skin cancers occurred in 0.5% of ustekinumab-treated subjects (0.64 events per hundred patient- years) and 0.2% of subjects receiving placebo (0.40 events per hundred patient-years). 6.2 Immunogenicity The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the studies described below with the incidence of anti-drug antibodies in other studies, including those of ustekinumab or of other ustekinumab products. Approximately 6 to 12.4% of subjects treated with ustekinumab in clinical trials in subjects with plaque psoriasis and psoriatic arthritis developed antibodies to ustekinumab, which were generally low-titer. In clinical trials in subjects with plaque psoriasis, antibodies to ustekinumab were associated with reduced or undetectable serum ustekinumab concentrations and reduced efficacy. In trials in subjects with plaque psoriasis, the majority of subjects who were positive for antibodies to ustekinumab had neutralizing antibodies. In clinical trials in subjects with Crohn’s disease and ulcerative colitis, 2.9% and 4.6% of subjects, respectively, developed antibodies to ustekinumab when treated with ustekinumab for approximately one year. No apparent association between the development of antibodies to ustekinumab and the development of injection site reactions was seen. 6.3 Postmarketing Experience The following adverse reactions have been reported during post-approval use of ustekinumab products. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to ustekinumab product exposure. Immune system disorders: Hypersensitivity reactions (e.g., anaphylaxis, angioedema, dyspnea, rash, urticaria), including a fatal case that presented with chest tightness and dyspnea during infusion of the first dose. Infections and infestations: Lower respiratory tract infection (including opportunistic fungal infections and tuberculosis). Neurological disorders: Posterior Reversible Encephalopathy Syndrome (PRES). Respiratory, thoracic and mediastinal disorders: Interstitial pneumonia, eosinophilic pneumonia and cryptogenic organizing pneumonia. Skin reactions: Pustular psoriasis, erythrodermic psoriasis, hypersensitivity vasculitis.
