This study evaluated the effectiveness and tolerability of Guselkumab in the treatment of psoriatic arthritis in clinical practice. The results showed that Guselkumab effectively controlled both joint and skin manifestations. No new safety concerns were found, and the majority of patients continued the treatment after 2 years of follow-up.
Guselkumab is a monoclonal antibody that selectively blocks the p19 subunit of interleukin 23 and has been approved for the treatment of moderate to severe psoriasis and active psoriatic arthritis in adult patients due to its efficacy in different clinical trials. Therefore, itis important to know the performance of guselkumab in this setting of patients in clinical practice given that a high percentage of them are not represented in these clinical trials. Our objective was to evaluate the effectiveness and tolerability of guselkumab in clinical practice in the first patients with psoriasis and psoriatic arthritis treated since the date of its approval for psoriasis in Spain, in joint dermatology-rheumatology clinics. A multicenter retrospective data collection was carried out, in which 14 hospitals participated, including a total of 90 patients with psoriatic arthritis confirmed by a rheumatologist. Data collection was recorded at baseline and at weeks 12, 24, and 52 for both the articular and cutaneous domains. Ninety PsA patients started treatment with guselkumab and therefore were included in this study. The vast majority had already failed to at least to one biologic therapyprior guselkumab prescription. The median age was 55 years, 61% were female and 46% had a BMI >= 30 kg/m(2). Sixty-nine percent suffered from peripheral arthritis, and in 34% an axial involvement was also detected; dactylitis or enthesitis was present in 24% and 29% of patients, respectively. Guselkumab was effective in controlling both articular and skin manifestations of PsA patients. Absolute PASI significantly decreased from 10.5 to 4.8, 1.9 and 1.3 at weeks 12, 24, and 52, respectively. In 29 out of 61 (48%) of cases, DAPSA was moderate or high, and patients showed a significant reduction in DAPSA at 12, 24, and 52 weeks of treatment (mean DAPSA values at baseline and follow up were 29, 20, 16, and 14, respectively). Patients with DAPSA in low activity or in remission at the time of initiation of guselkumab maintained response at the end of the study period. No new safety concerns were detected. Seventy-eight out of 90 patients (84.4%) persisted on treatment after 2 years follow-up. Our experience suggests that guselkumab isan effective drug for PsA and PsO patients in clinical practice with good tolerability and no additional safety signals, making it a new therapeutic alternative for the treatment of PsA and PsO patients.
