Phase 3 Studies Comparing Brodalumab with Ustekinumab in Psoriasis
N Engl J Med 2015 Oct;373(14):1318-28.PMID:26422722DOI:10.1056/NEJMoa1503824.
Background: Early clinical studies suggested that the anti-interleukin-17 receptor A monoclonal antibody Brodalumab has efficacy in the treatment of psoriasis. Methods: In two phase 3 studies (AMAGINE-2 and AMAGINE-3), patients with moderate-to-severe psoriasis were randomly assigned to receive Brodalumab (210 mg or 140 mg every 2 weeks), ustekinumab (45 mg for patients with a body weight ≤100 kg and 90 mg for patients >100 kg), or placebo. At week 12, patients receiving Brodalumab were randomly assigned again to receive a Brodalumab maintenance dose of 210 mg every 2 weeks or 140 mg every 2 weeks, every 4 weeks, or every 8 weeks; patients receiving ustekinumab continued to receive ustekinumab every 12 weeks, and patients receiving placebo received 210 mg of Brodalumab every 2 weeks. The primary aims were to evaluate the superiority of Brodalumab over placebo at week 12 with respect to at least a 75% reduction in the psoriasis area-and-severity index score (PASI 75) and a static physician's global assessment (sPGA) score of 0 or 1 (clear or almost clear skin), as well as the superiority of Brodalumab over ustekinumab at week 12 with respect to a 100% reduction in PASI score (PASI 100). Results: At week 12, the PASI 75 response rates were higher with Brodalumab at the 210-mg and 140-mg doses than with placebo (86% and 67%, respectively, vs. 8% [AMAGINE-2] and 85% and 69%, respectively, vs. 6% [AMAGINE-3]; P<0.001); the rates of sPGA scores of 0 or 1 were also higher with Brodalumab (P<0.001). The week 12 PASI 100 response rates were significantly higher with 210 mg of Brodalumab than with ustekinumab (44% vs. 22% [AMAGINE-2] and 37% vs. 19% [AMAGINE-3], P<0.001). The PASI 100 response rates with 140 mg of Brodalumab were 26% in AMAGINE-2 (P=0.08 for the comparison with ustekinumab) and 27% in AMAGINE-3 (P=0.007). Rates of neutropenia were higher with Brodalumab and with ustekinumab than with placebo. Mild or moderate candida infections were more frequent with Brodalumab than with ustekinumab or placebo. Through week 52, the rates of serious infectious episodes were 1.0 (AMAGINE-2) and 1.3 (AMAGINE-3) per 100 patient-years of exposure to Brodalumab. Conclusions: Brodalumab treatment resulted in significant clinical improvements in patients with moderate-to-severe psoriasis.

Pathophysiology, Clinical Presentation, and Treatment of Psoriasis: A Review
JAMA 2020 May 19;323(19):1945-1960.PMID:32427307DOI:10.1001/jama.2020.4006.
Importance: Approximately 125 million people worldwide have psoriasis. Patients with psoriasis experience substantial morbidity and increased rates of inflammatory arthritis, cardiometabolic diseases, and mental health disorders. Observations: Plaque psoriasis is the most common variant of psoriasis. The most rapid advancements addressing plaque psoriasis have been in its pathogenesis, genetics, comorbidities, and biologic treatments. Plaque psoriasis is associated with a number of comorbidities including psoriatic arthritis, cardiometabolic diseases, and depression. For patients with mild psoriasis, topical agents remain the mainstay of treatment, and they include topical corticosteroids, vitamin D analogues, calcineurin inhibitors, and keratolytics. The American Academy of Dermatology-National Psoriasis Foundation guidelines recommend biologics as an option for first-line treatment of moderate to severe plaque psoriasis because of their efficacy in treating it and acceptable safety profiles. Specifically, inhibitors to tumor necrosis factor α (TNF-α) include etanercept, adalimumab, certolizumab, and infliximab. Other biologics inhibit cytokines such as the p40 subunit of the cytokines IL-12 and IL-13 (ustekinumab), IL-17 (secukinumab, ixekizumab, bimekizumab, and Brodalumab), and the p19 subunit of IL-23 (guselkumab, tildrakizumab, risankizumab, and mirikizumab). Biologics that inhibit TNF-α, p40IL-12/23, and IL-17 are also approved for the treatment of psoriatic arthritis. Oral treatments include traditional agents such as methotrexate, acitretin, cyclosporine, and the advanced small molecule apremilast, which is a phosphodiesterase 4 inhibitor. The most commonly prescribed light therapy used to treat plaque psoriasis is narrowband UV-B phototherapy. Conclusions and relevance: Psoriasis is an inflammatory skin disease that is associated with multiple comorbidities and substantially diminishes patients' quality of life. Topical therapies remain the cornerstone for treating mild psoriasis. Therapeutic advancements for moderate to severe plaque psoriasis include biologics that inhibit TNF-α, p40IL-12/23, IL-17, and p19IL-23, as well as an oral phosphodiesterase 4 inhibitor.
Short-Term Efficacy and Safety of IL-17, IL-12/23, and IL-23 Inhibitors Brodalumab, Secukinumab, Ixekizumab, Ustekinumab, Guselkumab, Tildrakizumab, and Risankizumab for the Treatment of Moderate to Severe Plaque Psoriasis: A Systematic Review and Network Meta-Analysis of Randomized Controlled Trials
J Immunol Res 2019 Sep 10;2019:2546161.PMID:31583255DOI:10.1155/2019/2546161.
Background: The role of interleukin-12 (IL-12), interleukin-23 (IL-23), and interleukin-17 (IL-17) has been recognized in psoriasis pathogenesis, and new drugs targeting this axis have already been developed which may provide a new therapeutic approach for patients with moderate to severe psoriasis. Objective: To compare the direct and indirect evidences of the efficacy and safety of Brodalumab, secukinumab, ixekizumab, ustekinumab, guselkumab, tildrakizumab, and risankizumab in the short-term treatment of moderate to severe plaque psoriasis using network meta-analysis (NMA). Methods: A comprehensive literature search was performed in PubMed, EMBASE, and Cochrane Central Register of Controlled Trials for the available relevant studies. NMA was conducted by Stata 15.0 software using relative risks (RR) with 95% confidence interval to assess the clinical effectiveness and safety. Ranked the efficacy and safety for each drug accordance with the surface under the cumulative ranking curve (SUCRA). Results: This meta-analysis included 28 studies. All the interventions performed better than placebo in short-term achievement. Based on the result of SUCRA, ixekizumab 80 mg every 2 weeks ranked the highest in short-term achievement of PASI 75 (SUCRA = 93.0%). Brodalumab 210 mg ranked the highest in short-term achievement of PASI 100 (SUCRA = 85.0%). Secukinumab 300 mg ranked the highest in short-term achievement of sPGA 0/1 or IGA 0/1 or PGA 0/1 (SUCRA = 98.1%). In terms of having a risk of adverse events, the rates were higher in Brodalumab, secukinumab, ixekizumab, and ustekinumab 45 mg compared with placebo. Ixekizumab 80 mg every 4 weeks ranked the highest in the risk of adverse events during short-term treatment (SUCRA = 4.5%). Guselkumab 50 mg ranked the highest in the risk of serious adverse events during short-term treatment (SUCRA = 25.9%). Ixekizumab 80 mg every 4 weeks ranked the highest in the risk of discontinuations due to adverse events during short-ter treatment (SUCRA = 10.7%). Conclusions: IL-17, IL-12/23, and IL-23 inhibitors had high efficacy in the achievement of PASI 75, PASI 100, and sPGA 0/1 or IGA 0/1 or PGA 0/1 in moderate to severe plaque psoriasis after 12 or 16 weeks of treatment. IL-17 inhibitors showed superior efficacy. However, its clinical safety was poor. Risankizumab appeared to have relatively high efficacy and low risk. The clinical tolerance of other biological agents needs to be further observed.
The safety of Brodalumab for the treatment of psoriasis
Expert Opin Drug Saf 2020 Apr;19(4):365-372.PMID:32053396DOI:10.1080/14740338.2020.1730326.
Introduction: Brodalumab is a newly developed targeted biologic agent for the treatment of psoriasis that blocks IL-17 receptor A.Areas covered: This review sought to provide a detailed overview on safety of Brodalumab for the treatment of psoriasis. A PubMed search was conducted for relevant literature. Here we review the efficacy and safety data from key phase II, phase III and open-label extension clinical trials, as well as systematic reviews and meta-analyses.Expert opinion: The unique mechanism of action of Brodalumab offers advantages on efficacy over other targeted treatments, with a quick onset of action and long-term maintenance of treatment response. Brodalumab has a favorable safety profile, similar to other IL-17 inhibitors. Infections, especially mucocutaneous candidiasis, must be monitored. Suicidal ideation was detected in Brodalumab trials, although a causal relationship has not been revealed. Brodalumab is a highly efficacious and comparably safe therapeutic choice in patients with moderate to severe psoriasis, especially when rapid control of the disease is desired.
Brodalumab for the treatment of psoriasis
Expert Rev Clin Immunol 2016 Dec;12(12):1255-1271.PMID:27718760DOI:10.1080/1744666X.2016.1246957.
Psoriasis is a complex disease in which the alteration of the IL-23/Th17 axis appears to be crucial for its pathogenic mechanisms, and anti-IL17 agents are rapidly becoming important therapeutic tools. Brodalumab, a fully human Chinese hamster ovary cell-derived immunoglobulin G2 (IgG2) anti-IL-17RA monoclonal antibody, is currently the most-developed treatment that binds to the IL-17RA. The authors review and provide updates of efficacy and safety by several studies on Brodalumab. Areas covered: A PubMed search was performed for relevant literature. Among the trials of Brodalumab, the most common adverse events included nasopharyngitis, headache, upper respiratory tract infection, and arthralgia. Suicidal ideation and completed suicides had been observed in the Brodalumab programme, although evidence to date was quoted as not suggesting a causal association. Expert commentary: By blocking the IL-17 receptor A, Brodalumab antagonizes signaling from IL-17A, IL-17F, IL-17A/F and IL-25, and this probably contributes to the high efficacy observed in clinical trials. Considering the different therapeutic target and the potential biological implications that blocking IL-17RA instead of IL-17A might have, Brodalumab may not necessarily belong to the same class that includes secukinumab and ixekizumab, but it may be classified in a distinct group.
