Abstract
BACKGROUND
Switch patterns among different biologics and from originators to biosimilars (and vice versa) can be complex in patients with psoriasis (PsO) and psoriatic arthritis (PsA).
OBJECTIVE
To describe switching pattern of biological drugs in PsO/PsA patients and to explore predictors of multiple switches and switch-back.
RESEARCH DESIGN AND METHODS
A large-scale retrospective cohort study was conducted using the Italian VALORE database. Bio-naïve users treated for PsO/PsA during 2010-2022 were included. Time to switch/swap and predictors of multiple switches and switch-back were analyzed.
RESULTS
30,700 bio-naïve users were included. At 3 and 5 years of follow-up, patients with at least one switch/swap were 37.1% and 47.8%, respectively. The median time to first switch/swap was significantly shorter (p-value:<0.001) for TNF-α inhibitors (2,068 days) than anti-IL (2,780 days). At one year of follow-up patients starting with IL-23 switched/swapped biological therapy less frequently than those with anti-IL-12/23 and anti-IL-17 (4.9% vs. 8.7% and 9.4%, respectively). Patients starting with anti-IL-12/23 reported a significantly lower risk of multiple switches and switch-back (0.74, 95%CI: 0.67-0.83; 0.58, 95%CI:0.44-0.77, respectively) than those with TNF-α inhibitors.
CONCLUSIONS
Patients with PsO/PsA starting with TNF-α inhibitors switch/swap more rapidly and frequently than those with anti-IL, which are also associated with a reduced risk of multiple switches during follow-up.
