Efficacy of biological treatment of moderate to severe psoriasis - analysis from the BIOREP Registry
Abstract
Objective: Evaluation of the effectiveness of biological treatment of psoriasis according to the achievement of PASI 75, 90 and 100 in each group of biologics. Methods: A retrospective evaluation of patients diagnosed with plaque psoriasis from the BIOREP registry, who were treated with anti-TNF, anti-IL-12/23, anti-IL-17, or anti-IL-23 drugs during the registry follow-up period was performed.
Results: The total study population of 2,873 patients included 1,832 males (63.8%) and 1,041 females (36.2%). The mean age at the time of diagnosis was 24.8 +- 13.5 years, the mean age at the time of initiation of the first biologic was 46.0 +- 13.0 years.
The average time from the diagnosis of psoriasis to the first biological therapy was 21.2 +- 12.1 years. Psoriatic arthritis was diagnosed in 1,008 (35.1%) patients, 70.7% of patients had at least one comorbidity and 72.9% of patients with overweight or obese.
A total of 4,938 treatment series were recorded in the evaluated patients; anti-TNF (2,961 series, 60.0%), anti-IL-12/23 (626 series, 12.7%), anti-IL-17 (1,008 series, 20.4%) and anti-IL-23 (343 series, 6.9%). After 3-4 months of treatment, PASI 75 was achieved in 64.9% of cases, PASI 90 in 42.5% of cases and PASI 100 in 23.4% of cases with a further increase at 6 months (PASI 75, 90 and 100 in 76,9%, 55.6% and 32.7%, respectively) and maintaining response until 24 months of treatment.
The higher achievement of PASI75/90/100 was in the group treated with anti-IL-17 and anti-IL-23 even with a faster response rate compared to anti-TNF and anti IL-12/23. A higher achievement of PASI75/90/100 was observed in naive patients (with no previous biological treatment).
Conclusion: The analysis of the BIOREP registry confirmed data from registries of other countries as well as meta-analyzes of clinical studies. Although anti-TNF drugs have made significant advances in the treatment of psoriasis and adalimumab is still the most widely used drug, newer molecules provide higher efficacy.
Our analysis demonstrates a significant response in all PASI categories as well as a faster response to anti-IL-23 and anti-IL-17 drugs compared to older groups of biologics. Early and effective treatment of severe plaque psoriasis is important not only to improve quality of life and to reduce the risk of comorbidities, but also to achieve the highest response and the consequent long-term persistence on the treatment.
