On-label persistence in psoriasis after switching to guselkumab, tumor necrosis factor inhibitors, interleukin-17 inhibitors, or apremilast from other advanced therapies.
To compare on-label persistence among adults with psoriasis who switched from other advanced therapies to guselkumab versus subcutaneous tumor necrosis factor inhibitors (SC TNFi), subcutaneous interleukin-17 inhibitors (SC IL-17i), or apremilast.
Materials and methods
This retrospective cohort study used U.S. claims data from the IQVIA PharMetrics® Plus database (2016- 2023). Overlap propensity score weights were used to balance cohorts on baseline characteristics. On-label persistence was defined as the absence of drug discontinuation (event) and any dose change relative to the U.S. label (censoring). Survival analyses were used to assess on-label persistence from the start of the maintenance phase.
Results
At 12, 18, and 24 months after the start of the maintenance phase, respectively, on-label persistence was 190%, 180%, and 179% more likely on guselkumab versus SC TNFi; 78%, 87%, and 91% more likely on guselkumab versus SC IL-17i; and 187%, 199%, and 193% more likely on guselkumab versus apremilast (all p < 0.001).
Conclusions
Patients experiencing suboptimal outcomes with other psoriasis-indicated advanced therapies achieved higher on-label persistence after switching to guselkumab, raising the potential for improved disease control relative to other treatment options.
