Biologic therapies have revolutionized the treatment of moderate‐to‐severe psoriasis. However, for reasons largely unknown, many patients do not respond or lose response to these drugs. To evaluate demographic, social and clinical factors that could be used predict effectiveness stratify biologic in Using a multicentre, observational, prospective pharmacovigilance study (BADBIR), we identified biologic‐naive starting biologics with outcome data at 6 (n = 3079) 12 3110) months. Associations...

Patients with psoriasis enrolled in clinical trials of biologics may not be representative the real-world population. There is evidence that patients ineligible for such have a greater risk serious adverse events (SAEs), but effect on drug discontinuation and effectiveness are unknown.To determine whether (1) discontinuation, (2) effectiveness, (3) rates SAEs differ categorized as eligible or trials.An observational study using 157 dermatology centers United Kingdom Republic Ireland was...

This large prospective cohort study provides insights into the differential drug survival of second-line biologic therapies in routine clinical practice. We found that 77% patients who were switched to a second therapy continued receive new treatment for at least 12 months. shows clearly experiencing failure with one can benefit from switching another. However, discontinuation due AEs was more common among those discontinued first-line because AEs. The results this should support decision...
