Primary Outcome Measures:
  • Change From Randomization in PASI Score to Week 24 (Week 18 of Etanercept Monotherapy/Placebo) [ Time Frame: Randomization to Week 24. ]
    PASI score: range: 0 (none) to 72 (maximum). Body was divided into head, upper extremities, trunk and lower extremities; each area score was combined for final PASI. For each section, percent area of skin involved was estimated: 0 (0%) to 6 (90 - 100%), and severity was estimated by clinical signs: (erythema, induration, and desquamation); scale: 0 (none) to 4 (maximum). Final PASI= sum of severity parameters for each section times area score times weight of section (head: 0.1, upper extremities: 0.2, trunk: 0.3, lower extremities: 0.4). Change = PASI at Week 24 - PASI at baseline.


Secondary Outcome Measures:
  • PASI Area Under the Curve (AUC) Between Randomization and Week 24 [ Time Frame: Randomization to Week 24. ]
    PASI AUC = Area under the curve from randomization (Week 6) to Week 24.

  • Change From Randomization in PGA Score to Week 24 [ Time Frame: Randomization to Week 24. ]
    PGA score is based on dermatologist's assessment of disease averaged over all lesions. Overall lesions were graded for individual scores of induration, erythema, and scaling; range: 0 (no evidence) to 5 (severe). The sum of the 3 scores was divided by 3 to obtain a final PGA score. Higher scores indicate greater severity of disease. Change = PGA at Week 24 - PGA at baseline.

  • Relapse (Loss of 50% Improvement in PASI) During the 24 Weeks After Randomization [ Time Frame: Randomization to Week 24. ]
    Relapse was defined as the loss of 50% improvement in PASI.

  • Probability of Being Relapse Free During the 24 Weeks After Randomization [ Time Frame: Randomization to Week 24. ]
    Relapse was defined as loss of 50% improvement in PASI. The time to relapse was estimated using a Kaplan-Meier analysis.

  • Percent (%) Change of PASI Score From Randomization to Week 24 [ Time Frame: Randomization to Week 24. ]
    Percent improvement in PASI score was calculated from Week 6 to Week 24.

  • Change From Randomization in DLQI to Week 24 [ Time Frame: Randomization to Week 24. ]
    DLQI is the dermatology-specific quality of life measure used for psoriatic population. The 10-item questionnaire has a score range of 0 to 30 with higher scores indicating poor quality of life. An estimate of the minimal clinically important difference of the DLQI total score is a 5 point improvement. Total score range: 0 (best) to 30 (worst).

  • DLQI at Each Visit From Baseline [ Time Frame: Baseline to Week 24. ]
    DLQI is the dermatology-specific quality of life measure used for psoriatic population. The 10 item questionnaire has a score range of 0 to 30 with higher scores indicating poor quality of life. An estimate of the minimal clinically important difference of the DLQI total score is a 5 point improvement. Total score range: 0 (best) to 30 (worst).

  • Percentage of Rebound Effects [ Time Frame: Baseline to Week 24. ]
    Rebound effects was defined as worsening of psoriasis to 125% of the baseline PASI or appearance of psoriasis variants such as erythrodermic or pustular psoriasis within 12 weeks of discontinuation of therapy.
