Adverse Reactions in Clinical Trials of Subcutaneous COSENTYX Adverse Reactions from Clinical Trials in Adults with PsO A total of 3,430 adult subjects with PsO were treated with COSENTYX in controlled and uncontrolled clinical trials. Of these, 1,641 subjects were treated with COSENTYX for at least 1 year. Four placebo-controlled Phase 3 trials in PsO subjects (Trials PsO1, PsO2, PsO3, and PsO4) were pooled to evaluate the safety of COSENTYX in comparison to placebo up to 12 weeks after treatment initiation. In total, 2,077 subjects were evaluated (691 in the COSENTYX 300 mg group, 692 in the COSENTYX 150 mg group, and 694 in the placebo group). Subjects randomized to COSENTYX received 300 mg or 150 mg doses subcutaneously at Weeks 0, 1, 2, 3, and 4 followed by the same dose every 4 weeks [see Clinical Studies (14)] . Table 2 summarizes the adverse reactions that occurred at a rate of at least 1% and at a higher rate in the COSENTYX groups than the placebo group during the 12-week placebo-controlled period of these trials. Table 2: Adverse Reactions Reported by Greater Than 1% of Adult Subjects With PsO (and at a Higher Rate in Subjects Treated with COSENTYX) Through Week 12 in Trials PsO1, PsO2, PsO3, and PsO4 COSENTYX Adverse reactions 300 mg (N = 691) n (%) 150 mg (N = 692) n (%) Placebo (N = 694) n (%) Nasopharyngitis 79 (11.4) 85 (12.3) 60 (8.6) Diarrhea 28 (4.1) 18 (2.6) 10 (1.4) Upper respiratory tract infection 17 (2.5) 22 (3.2) 5 (0.7) Rhinitis 10 (1.4) 10 (1.4) 5 (0.7) Oral herpes 9 (1.3) 1 (0.1) 2 (0.3) Pharyngitis 8 (1.2) 7 (1.0) 0 (0) Urticaria 4 (0.6) 8 (1.2) 1 (0.1) Rhinorrhea 8 (1.2) 2 (0.3) 1 (0.1) Adverse reactions that occurred in subjects treated with COSENTYX at rates less than 1% in the placebo-controlled period of Trials PsO1, PsO2, PsO3, and PsO4 through Week 12 included: sinusitis, tinea pedis, conjunctivitis, tonsillitis, oral candidiasis, impetigo, otitis media, otitis externa, IBD, increased liver transaminases, and neutropenia. Infections In the placebo-controlled period of the clinical trials in PsO (a total of 1,382 subjects treated with COSENTYX and 694 subjects treated with placebo up to 12 weeks), infections were reported in 28.7% of subjects treated with COSENTYX compared with 18.9% of subjects treated with placebo. Over the entire treatment period (a total of 3,430 PsO subjects treated with COSENTYX for up to 52 weeks for the majority of subjects), infections were reported in 47.5% of subjects treated with COSENTYX (0.9 per subject-year of follow-up) and serious infections were reported in 1.2% of subjects treated with COSENTYX (0.015 per subject-year of follow-up). Phase 3 data showed an increasing trend for some types of infection with increasing serum secukinumab concentrations. Candida infections, herpes viral infections, staphylococcal skin infections, and infections requiring treatment increased as serum secukinumab concentration increased. In the PsO open-label extension of Trials PsO1 and PsO2 (median follow-up of 3.9 years), representing 3,582 subject-years of exposure, 74% of COSENTYX treated subjects reported infections (55 per 100 subject-years) and serious infections were reported in 4.5% of COSENTYX treated subjects (1.4 per 100 subject-years). Sepsis was reported in 5 COSENTYX treated subjects (0.2 per 100 subject-years). Neutropenia was observed in controlled portion of clinical trials. Most cases of COSENTYX associated neutropenia were transient and reversible. No serious infections were associated with cases of neutropenia. In the open-label extension of Trials PsO1 and PsO2, neutropenia (ANC < 1 x 10 9 /L) was reported in 1% of COSENTYX treated subjects (0.3 per 100 subject-years). Some cases of serious infections were associated with neutropenia; however, the causal relationship was not established. Inflammatory Bowel Disease Cases of IBD, in some cases serious, were observed in subjects treated with COSENTYX in clinical trials. In the PsO program, with 3,430 subjects exposed to COSENTYX over the entire treatment period for up to 52 weeks (2,725 subject-years), there were 3 cases (0.11 per 100 subject-years) of exacerbation of CD, 2 cases (0.08 per 100 subject-years) of exacerbation of UC, and 2 cases (0.08 per 100 subject-years) of new onset UC. There were no IBD cases in placebo-treated subjects (N = 793; 176 subject-years) during the 12-week placebo-controlled period. One case of exacerbation of Crohn’s disease in a subject treated with COSENTYX subject was reported in open-label portions of clinical trials in PsO. Adverse Reactions from Clinical Trials in Pediatric Subjects with PsO The safety of COSENTYX was assessed in two Phase 3 trials in pediatric subjects with PsO. The first was a randomized, double-blind, placebo and active-controlled, 236-week trial (Trial PsO8) that enrolled 162 pediatric subjects 6 years of age and older, with severe PsO (defined by PASI score ≥ 20, an IGA modified 2011 score of 4, and involving ≥ 10% of the body surface area [BSA]) who were candidates for systemic therapy. The 162 subjects were randomized to receive placebo, a biologic active control, or COSENTYX. In the COSENTYX groups, subjects with body weight (BW) less than 25 kg received 75 mg, subjects with BW 25 to less than 50 kg received either 75 mg or 150 mg (2 times the recommended dose), and subjects with BW of at least 50 kg received either 150 mg or 300 mg (2 times the recommended dose). Subjects were dosed at Weeks 0, 1, 2, 3, and 4 and every 4 weeks thereafter. The second trial was a randomized, open-label, 208-week trial (Trial PsO9; NCT03668613) of 84 pediatric subjects 6 years of age and older with moderate to severe PsO (defined by a PASI score ≥ 12, IGA mod 2011 score of ≥ 3, and BSA involvement of ≥ 10% at randomization) who were randomized into two COSENTYX arms [Arm 1: 75 mg for BW < 50 kg or 150 mg for ≥ 50 kg; and Arm 2: 75 mg for BW < 25 kg, 150 mg for BW ≥ 25 kg and < 50 kg, or 300 mg for BW ≥ 50 kg]. Subjects were dosed at Weeks 0, 1, 2, 3, and 4 and every 4 weeks thereafter. The safety profile of COSENTYX reported in these trials was consistent with the safety profile reported in adult PsO trials. Infections One case of methicillin-resistant Staphylococcus aureus (MRSA) toxic shock syndrome (TSS) was reported in a COSENTYX treated pediatric subject during the placebo-controlled period. In the pediatric safety pool, which includes all subjects who took at least one dose of COSENTYX during the treatment periods [198 subjects (287 subject-years)], 22 (11%) subjects reported ≥ Common Terminology Criteria for Adverse Events (CTCAE) Grade 2 neutropenia (≥ 1,000 to < 1,500 cells/mm 3 ) with 57% of subjects followed for one year or more and 30% of subjects followed for two years or more. During the placebo-controlled period, which included a total of 80 pediatric subjects treated with COSENTYX and 41 subjects treated with placebo up to 12 weeks, ≥ CTCAE Grade 2 neutropenia was reported in 3 (4%) of the subjects treated with COSENTYX compared with no subjects treated with placebo. No serious infections were associated with cases of neutropenia. Adverse Reactions from Clinical Trials in Adults with PsA COSENTYX was studied in two placebo-controlled PsA trials with 1,003 adult patients (703 patients on COSENTYX and 300 patients on placebo). Of the 703 patients who received COSENTYX, 299 patients received a subcutaneous loading dose of COSENTYX (PsA1) and 404 patients received an intravenous loading dose of secukinumab (PsA2) followed by COSENTYX administered by subcutaneous injection every 4 weeks. During the 16-week placebo-controlled period of the trials in patients with PsA, the overall proportion of patients with adverse events was similar in the secukinumab and placebo-treatment groups (59% and 58%, respectively). The adverse events that occurred at a proportion of at least 2% and at a higher proportion in the COSENTYX groups than the placebo groups during the 16-week placebo-controlled period were nasopharyngitis, upper respiratory tract infection, headache, nausea, and hypercholesterolemia. The safety profile observed in adult patients with PsA treated with COSENTYX is consistent with the safety profile in the PsO trials in adults. Similar to the clinical trials in patients with PsO, there was an increased proportion of patients with infections in the COSENTYX groups (29%) compared to placebo group (26%). There were cases of CD and UC in the secukinumab group that included patients who experienced either exacerbations or the development of new disease. There were three cases of IBD, of which two patients received secukinumab and one received placebo. Adverse Reactions from Clinical Trials in Adults with AS COSENTYX was studied in two placebo-controlled AS trials with 590 adult patients (394 patients on COSENTYX and 196 patients on placebo). Of the 394 patients who received COSENTYX, 145 patients received a subcutaneous load of COSENTYX (study AS1), and 249 received an intravenous loading dose of secukinumab (study AS2) followed by COSENTYX administered by subcutaneous injection every 4 weeks. During the 16-week placebo-controlled period of the trials in patients with AS, the overall proportion of patients with adverse events was higher in the secukinumab groups than the placebo-treatment groups (66% and 59%, respectively). The adverse events that occurred at a proportion of at least 2% and at a higher proportion in the COSENTYX groups than the placebo groups during the 16-week placebo-controlled period were nasopharyngitis, nausea, and upper respiratory tract infection. The safety profile observed in patients with AS treated with COSENTYX is consistent with the safety profile in PsO clinical trials. In a third controlled trial of AS (study AS3), the safety profile of the 300 mg dose of COSENTYX was consistent with the safety profile of the 150 mg dose of COSENTYX. Similar to clinical trials in patients with PsO, there was an increased proportion of patients with infections in the COSENTYX groups (31%) compared to the placebo group (18%). In the original AS program, with 571 patients exposed to COSENTYX, there were 8 cases of IBD during the entire treatment period [5 cases of Crohn’s (0.7 per 100 patient-years) and 3 cases of UC (0.4 per 100 patient-years)]. During the placebo-controlled 16-week period, there were 2 Crohn’s disease exacerbations and 1 new onset UC case that was a serious adverse event in patients treated with COSENTYX compared to none of the patients treated with placebo. During the remainder of the trial when all patients received COSENTYX, 1 patient developed Crohn’s disease, 2 patients had Crohn’s exacerbations, 1 patient developed UC, and 1 patient had an UC exacerbation. Adverse Reactions from Clinical Trials in Adults with nr-axSpA COSENTYX was studied in one randomized, double-blind, placebo-controlled nr-axSpA trial with 555 adult patients (185 patients received a loading COSENTYX dose, 184 patients did not receive a loading COSENTYX dose, and 186 patients received placebo). The safety profile for patients with nr-axSpA treated with COSENTYX was overall similar to the safety profile seen in patients with AS and other previous experience with COSENTYX. Patients in nr-axSpA1 trial who received the loading dosing regimen compared to those without the loading regimen, had higher incidence of infections and infestations (92 per 100 patient-years versus 72 per 100 patient-years), including nasopharyngitis, upper respiratory tract infection and urinary tract infection, and gastrointestinal disorders (27 per 100 patient-years versus 22 per 100 patient-years), including gastritis, lower abdominal pain, colitis, diarrhea, and hematochezia. Adverse Reactions from Clinical Trials in Pediatric Patients with Juvenile Psoriatic Arthritis (JPsA) and ERA COSENTYX was studied in one double-blind, placebo-controlled, event-driven, randomized trial in 86 pediatric patients aged 2 to less than 18 years old with JPsA and ERA. The safety profile reported in this trial was consistent with the safety profile of secukinumab. Adverse Reactions from Clinical Trials in Adults with HS COSENTYX was studied in two 52-week, randomized, double-blind, placebo-controlled HS trials with 1,084 adult subjects (361 subjects received COSENTYX 300 mg every 2 weeks, 360 subjects received COSENTYX 300 mg every 4 weeks, and 363 subjects received placebo) with a total of 901 subject-years of COSENTYX exposure (the median duration of exposure for subjects treated with COSENTYX was 360 days). The safety profile of COSENTYX observed in these HS trials was consistent with the known safety profile of COSENTYX observed in the PsO trials. Infections During the 16-week placebo-controlled period, subjects who received COSENTYX 300 mg every 2 weeks had the highest incidence of fungal infections (5.3%), compared to subjects who received COSENTYX 300 mg every 4 weeks (4.2%) and subjects who received placebo (2.8%). With longer exposure, the rate of fungal infections remained higher for subjects who received COSENTYX 300 mg every 2 weeks (14.7/100 subject-years) compared to subjects who received COSENTYX 300 mg every 4 weeks (10.1/100 subject-years). The majority of the cases were reported as non-serious, non-severe, and resolved with anti-fungal treatment. Inflammatory Bowel Disease In the open-labeled portion of HS clinical trials, five (0.7%) IBD adverse reactions were reported, all of which were serious and led to withdrawal of trial drug, and occurred only in subjects treated with COSENTYX 300 mg every 2 weeks. There were no IBD cases in subjects treated with COSENTYX 300 mg every 4 weeks. Adverse Reactions of Intravenous COSENTYX The safety of intravenous COSENTYX is based on the pharmacokinetic exposure and extrapolation of the established safety of subcutaneous COSENTYX in PsA, AS and nr-axSpA patients [see Clinical Pharmacology (12.3)] . 6.2 Postmarketing Experience The following adverse reactions have been reported during post-approval use of COSENTYX. Because they 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 drug exposure. Immune system disorders : anaphylaxis, angioedema, systemic vasculitis Skin and subcutaneous tissue disorders : eczematous eruptions (atopic dermatitis-like eruptions, dyshidrotic eczema, and erythroderma), cutaneous vasculitis, pyoderma gangrenosum Infections : bacterial, viral, and fungal opportunistic infections, including esophageal candidiasis, tracheobronchial candidiasis, cutaneous aspergillosis, cytomegalovirus gastroenteritis/colitis, herpes simplex encephalitis, herpes simplex keratitis, Pneumocystis jiroveci pneumonia, Hepatitis B virus reactivation, histoplasmosis, toxoplasmosis
