Szczegółowy opis

The recommended starting dose of etanercept for adult plaque psoriasis patients is a 50 mg dose given twice a week (BIW) for 3 months followed by a reduction to a maintenance dose of 50 mg once weekly (QW). While most patients with moderate to severe plaque psoriasis are managed satisfactorily on etanercept monotherapy, a proportion may require a modified or alternative treatment regimen (eg, to handle flares or loss of effect) at some point during their chronic management. Despite the clinical need, no published data from randomized controlled studies are currently available that demonstrate efficacy and safety of combined etanercept-based regimens in patients with plaque psoriasis.

The addition of an as-needed topical medication to the step-down dose of etanercept 50 mg once weekly administered after the initial 12 week period of 50 mg twice weekly may be a potential option for patients who may require adjunctive therapy. This study aimed to provide data on this treatment option by estimating the difference in mean percent change in Psoriasis Area and Severity Index (PASI) scores between step-down etanercept 50 mg once weekly supplemented with as-needed topical medication and continuous treatment with etanercept 50 mg twice weekly.

Eligible patients will be enrolled in the study and will receive etanercept 50 mg twice weekly for 12 weeks. After 12 weeks of etanercept treatment, participants will be randomized in a 1:1 ratio to 1 of 2 treatment groups.

Percent Change in Psoriasis Area and Severity Index (PASI) From Week 12 to Week 24
Ramy czasowe: Week 12 and Week 24
The Psoriasis Area and Severity Index (PASI) score is a combination of the intensity of psoriasis, assessed by the erythema (reddening), induration (plaque thickness) and desquamation (scaling) on a scale from none (0), mild (1), moderate (2), severe (3) or very severe (4), together with the percentage of the area affected, rated on a scale from 0 to 6. PASI scoring is performed at four body areas, the head, arms, trunk, and legs. The total PASI score ranges from 0 to 72. The higher the total score, the more severe the disease. Change from Week 12 to Week 24 is presented as a percentage of the Week 12 value: Week 12 value - Week 24 value / Week 12 value * 100 so that a positive change indicates improvement. Change was adjusted for treatment using a mixed model.
