Psoriasis Not Reaching PASI 75 After Biologic Dose Escalation and Add-On Therapies

In moderate-to-severe psoriasis, treatment is guided by a measurable clearance target. When a biologic-based regimen — even after augmentation — still falls short of that goal, a defined next step is supported by evidence.

Previous Treatment — Failure Condition

Despite escalating the biologic dose or increasing its dosing frequency, and/or adding further agents such as topical high-potency corticosteroids (with or without a vitamin D analogue), methotrexate, acitretin, apremilast, or narrowband ultraviolet B phototherapy, the clinical target of PASI 75 (75% improvement in the Psoriasis Area Severity Index) was not achieved.

Clinical Goal for This Protocol

The target remains 75% improvement in the Psoriasis Area Severity Index (PASI 75).

Next-Line Approach (partial)

After failure of biologic escalation and add-on therapy, the evidence-based approach centres on switching to a different biologic agent. The complete structured regimen — including which agent, how it is selected, and the monitoring framework — is in the full protocol.

If clinically needed, all other therapies for psoriasis, including other biologics, may be switched with a different biologic agent with the possibility of improved efficacy, safety, and/or tolerability.
