Brodalumab is associated with high rates of complete clearance and quality of life improvement: a subgroup analysis of patients with psoriasis and concomitant psoriatic arthritis

Dermatology. 2022;238(4):620-629
  • L’obiettivo del presente studio è stato comparare l’efficacia di brodalumab rispetto a ustekinumab e l’impatto sulla qualità della vita nei pazienti affetti da psoriasi in placche moderata-severa.
  • Il trattamento con brodalumab ha determinato rapidi risultati e alti livelli di risoluzione completa e prolungata rispetto a ustekinumab, indipendentemente dal concomitante status della PsA.


Psoriatic arthritis (PsA) is a chronic inflammatory disease associated with psoriasis that significantly impairs physical function and quality of life (QoL). Prompt therapeutic intervention is crucial for limiting PsA progression and preventing disability.

The aim of this study was to compare the efficacy of brodalumab versus ustekin-umab and the impact on QoL in patients with moderate-to-severe plaque psoriasis, by concomitant PsA status.

This post hoc analysis of pooled data from the phase 3 AMAGINE-2 and -3 trials evaluated complete skin clearance (100% improvement of Psoriasis Area and Severity Index [PASI 100]), improvement in symptom severity (Psoriasis Symptom Inventory [PSI] response), and QoL (Dermatology Life Quality Index [DLQI] score of 0/1) by concomitant PsA status. A competing risk model assessed cumulative incidence over 52 weeks with outcomes of PASI 100 or inadequate response.

This analysis included 929 patients with moderate-to-severe psoriasis. Concomitant PsA was present in 79/339 (23%) and 110/590 (19%) patients receiving brodalumab 210 mg and ustekinumab, respectively. At Week 52, odds ratios (ORs) (95% confidence intervals [CIs]) for complete clearance with brodalumab versus ustekinumab were 3.15 (1.52-6.55, p = 0.0015) in patients with concomitant PsA and 3.05 (2.19-4.26, p <0.0001) in patients without concomitant PsA. Corresponding Week 52 ORs (95% CIs) for DLQI 0/1 with brodalumab versus ustekinumab were 2.05 (1.07-3.90, p = 0.0277) and 1.83 (1.32-2.53, p = 0.0002); Week 52 ORs (95% CIs) for PSI ≤8 with brodalumab versus ustekinumab were 3.42 (1.43-8.18, p = 0.0036) and 1.40 (1.01-1.95, p = 0.0434). The 52-week cumulative incidence of patients achieving PASI 100 was significantly higher for brodalumab versus ustekinumab in patients with concomitant PsA (p = 0.0001) and in those without concomitant PsA (p <0.0001).

Treatment with brodalumab rapidly results in high levels of complete and sustained skin clearance and greater cumulative treatment benefit in patients with moderate-to-severe psoriasis versus ustekinumab, regardless of concomitant PsA status.
