The journey of adult psoriasis patients towards biologics: past and present - Results from the BioCAPTURE registry

Abstract

Background: A considerable disease period often precedes initiation of a biologic in patients with psoriasis. Little is known about this important period in patients' lives. Evaluation of this 'journey' can reveal important insights and opportunities for physicians and healthcare decision makers.

Objectives: (i) To describe patient and treatment characteristics until the start of biologic treatment in patients with severe psoriasis, (ii) to assess shifts in early (2005-2009) versus established (2010-2015) biologics prescription periods, (iii) to assess changes in hospital/day care admissions before vs. after starting biologics.

Methods: Explorative, retrospective study on the treatment characteristics of the disease period until first biologic, presented with descriptive statistics of patients included in the BioCAPTURE registry. Journeys of 2005-2009 and 2010-2015 were compared with statistical tests to identify important shifts.

Results: Median TUS (time until conventional systemic) was 11.0 years and median TUB (time until biologic) was 18.9 years for all patients treated from 2005 to 2015. Most patients received three different conventional antipsoriatic systemic therapies. We noticed a small trend towards a shorter journey (TUB) with only two conventional systemic agents instead of three before initiating a biologic in later years (2010-2015, vs. 2005-2009). We also noticed a significant decrease in (day care) admissions comparing the two years before, versus the first two years after the start of a biologic treatment (17.7 vs. 8.6 admissions/100 follow-up years, P < 0.001). Cyclosporine, intensive topical treatment (dithranol), retinoids and PUVA therapy lost popularity in recent years.

Conclusion: The 'journey' of patients with psoriasis towards a biologic is still long and characterized by many different treatments. Shifts towards fewer conventional drugs before biologic initiation and a clear decrease in hospital and day care admissions before vs. after a biologic are seen. Improvement of this journey, especially in young or recently diagnosed patients, can decrease negative influences on patients' lives and reduce societal impact.
