Classification: C

Drug products: Cosentyx, Cosentyx®

ATC code: L04AC10

Substances: secukinumab


A randomized placebo-controlled trial in non-radiographic spondyloarthritis found higher 16-week secukinumab response rates for men. Most observational studies on secukinumab in axial spondyloarthritis and psoriatic arthritis have found worse treatment response and a higher risk of treatment discontinuation in women. There is some evidence of a higher risk of treatment discontinuation of secukinumab for women in psoriasis. Adjusted for body weight, secukinumab clearance is not dependent on the sex of the patient.

Additional information

The prevalence of ankylosing spondylitis in the Swedish adult population is 0.2%, with more men than women affected (0.23% vs. 0.14%) [1]. The overall prevalence of psoriasis in the adult Swedish population is 1.2%, psoriatic arthritis affects about 20% of these patients. In both psoriasis and psoriatic arthritis men and women are affected equally [2].

Pharmacokinetics and dosing

Secukinumab exposure is significantly impacted by body weight. Response rates were numerically higher in low body weight than in high body weight individuals in the randomized clinical trials that were conducted before the market approval. The recommended dose is 300 mg once monthly, but the label includes information on higher and lower dosing. Patient’s sex does not significantly affect the clearance of secukinumab when adjusted for body weight [3, 4].  


Axial spondyloarthritis and psoriatic arthritisIn a post-hoc analysis of a randomized placebo-controlled trial of secukinumab in non-radiographic spondyloarthritis, response rates at 16 weeks were consistently higher in male than in female patients (255 men, 300 women) [5].In an observational study of determinants of secukinumab retention rates in spondyloarthropathies were examined (90 men, 48 women). In axial spondyloarthritis one year retention rates were higher in women than in men (95% vs. 77%). However, in psoriatic arthritis (PsA), one year retention rates were higher in men than in women (89% vs. 66%) [6]. Drug retention rates of secukinumab in PsA (27 men, 22 women) and axial spondyloarthritis (58 men, 37 women) were examined in another observational study. The 1-year retention was 66% and the 2-year retention rate was 43%. Adjusted for comorbidities and previous treatments, the hazard ratio (HR) for discontinuation for men was significantly lower (HR=0.54). The main causes for discontinuation were lack of efficacy (59%) and adverse events (36%). No difference was found between axial spondyloarthritis and PsA [7].Drug retention and treatment response in the treatment of PsA with secukinumab was examined in an observational study (251 men, 357 women). Overall, the 24-month retention rate was 71%. Men had lower rates of discontinuation (HR=0.68), and a higher chance of achieving minimal disease activity (HR=1.60) [8]. An observational study on drug retention in PsA included 4649 PsA patients treated with biologics (adalimumab, ustekinumab, secukinumab), of which 354 men and 533 women were treated with secukinumab. The risk of treatment discontinuation in adjusted Cox models was higher in women (HR=1.40) [9].

PsoriasisIn an observational study of secukinumab-treated psoriasis (224 men, 106 women, 21.5% with PsA), the overall 1-year drug retention rate was 83%. Patient’s sex was not significantly associated with treatment discontinuation in a univariate analysis [10]. A similar study on drug retention in secukinumab-treated psoriasis (241 men, 143 women) showed no difference in drug retention in adjusted models between men and women [11].An observational study in patients with psoriasis (572 men, 377 women) treated with anti-IL 17 agents (51% secukinumab) did not find a significant difference in drug retention between men and women [12]. A larger study (2037 men, 1275 women) on drug retention of IL‑12/23, IL‑17 and IL‑23 inhibitors in psoriasis patients (28% treated with secukinumab) found a lower risk of treatment discontinuation for men  (HR=0.84), but sex-divided data were not presented for secukinumab [13]. Another observational study on retention of biologics in psoriasis patients with or without PsA  (3843 men, 1791 women) found a higher risk of drug discontinuation in women (HR=1.13) [14]. The study included 738 patients treated with secukinumab but sex-divided data were not presented.  

Adverse effects

In an observational study (188 men, 127 women) on predictors for treatment discontinuation in biologics-treated psoriasis, women reported lower treatment satisfaction in terms of “side effects” and “global satisfaction”. Women also reported more relevant adverse events in the context of biologic therapy (i.e. fungal and herpes simplex infections). The study included 396 treatment episodes (24 for secukinumab) but secukinumab specific data were not reported [15].
