SPS commentary:
In patients at high risk of joint damage, dose escalation to 100 mg every 4 weeks can be considered, which is in contrast to the use in psoriasis, where 100 mg every 8 weeks is the maximum dose. The SPC states that in psoriatic arthritis studies, there was an increased incidence of liver enzyme elevations with 4 weekly treatment as compared to 8 weekly treatment or placebo. Therefore when prescribing guselkumab as a 4 weekly regimen the manufacturers recommend baseline and ongoing liver testing, and if drug induced liver injury is suspected, guselkumab should be stopped.
