insurance company to approve their new biologic; while waiting for an insurance company to approve a new biologic, patients continue to suffer from their residual psoriasis. Navigating through new insurance paperwork, when switching from a drug that was already authorized to a new one, also entails greater cost to the physician’s practice, a cost that we did not include in our model. A limitation in this study is that the estimate of cost for switching a biologic may be low as failing one drug may make it more likely patients would fail a second one.


Adding a topical agent may be an effective, low cost, and safe approach to achieve clearing in patients with psoriasis who fail to achieve complete clearance from an initial biologic.
