Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: - The proportion of patients in each group in clinical remission (absolute PASI < 2) at year 1 after optimization (non-inferiority of intervention) - Optimization of extraction protocol for adalimumab serum trough levels and anti-drug antibodies (ADA) derived from micro-sampling technique. ;Secondary Objective: -The proportion of patients in each group who relapses [defined as the need for dose escalation (not in the standard based dosing arm)] -The proportion of patients in each group with serum trough levels (Ctrough) of adalimumab within the optimal interval -The proportion of patients in each group with anti-drug antibodies (ADA) against adalimumab (ADA positivity) -Evaluation of the cost-effectiveness of the intervention -Recording of demographic parameters during disease course monitored at baseline and at every visit (reflected by incidence, prevalence, mortality, standardized comorbidity incidence ratios and associations/risk factors) -Quality adjusted life years (QALY) -Determine inter- and intrapatient variability (IPV) -HRQoL EQ-5D-5L ;Primary end point(s): absolute PASI < 2 (clinical remission);Timepoint(s) of evaluation of this end point: over the course of 48 weeks | — |
