简要总结
W11-050 is a Mexican open label multicenter study that has been designed to further assess the safety and efficacy of adalimumab in the treatment of patients with active plaque psoriasis who have failed prior conventional systemic psoriasis treatment or who are candidates for systemic therapy.
详细描述
Up to 150 subjects having a diagnosis of active plaque psoriasis and fulfilling the study eligibility criteria were enrolled in Mexico. Adalimumab was administered as follows: 80 mg at baseline, followed by 40 mg every other week (eow; starting at week 1 until week 15). The study drug was self administered via subcutaneous (sc) injection. Safety and efficacy measures were performed throughout the study.

排除标准
- •Prior treatment with any investigational agent within 30 days, or five half-lives of the product, which ever is longer. Subject has been treated with any investigational drug of chemical or biologic nature within a minimum of 30 days or five half lives (whichever is longer) of the drug prior to study entry (Baseline Visit)
- •Subject has other active skin diseases or skin infections (bacterial, fungal, or viral) that may interfere with the evaluation of psoriasis or compromise the subject's safety

- •Subject has been initiated on a new systemic agent within the last four weeks prior to the Baseline visit
- •Patients with history of atopy
- •Patients with any other autoimmune disease such as systemic lupus erythematosus (SLE) , Sdx Sjögren, vasculitis etc
- •Known hypersensitivity to the excipients of adalimumab as stated in the label
- •Female subjects who are pregnant or breast-feeding or considering becoming pregnant during the study

Percentage of Participants With Psoriasis Area and Severity Index (PASI)-75 Response at Week 4
时间窗: Week 4
PASI is a composite score based on the degree of effect on body surface area of psoriasis and the extension of erythema (reddening), induration (plaque thickness), desquamation (scaling) of the lesions and area affected as observed on the day of examination. The score ranges from 0 (no psoriasis) to 72 (very severe psoriasis). PASI-75 response is the percentage of participants who achieved at least a 75% reduction (improvement) from baseline in PASI score at Week 4. The improvement in PASI score was used as a measure of efficacy.
Percentage of Participants With Psoriasis Area and Severity Index (PASI)-75 Response at Week 16
时间窗: Week 16
PASI is a composite score based on the degree of effect on body surface area of psoriasis and the extension of erythema (reddening), induration (plaque thickness), desquamation (scaling) of the lesions and area affected as observed on the day of examination. The score ranges from 0 (no psoriasis) to 72 (very severe psoriasis). PASI-75 response is the percentage of participants who achieved at least a 75% reduction (improvement) from baseline in PASI score at Week 16. The improvement in PASI score was used as a measure of efficacy.
Percentage of Participants With a Dermatology Life Quality Index (DLQI) Score < 6 at Week 4
时间窗: Week 4
Dermatology Life Quality Index (DLQI) score is a participant-reported outcome consisting of a set of 10 questions regarding the degree to which the participant's skin has affected certain behaviors and quality of life over the last week. Responses to each are: very much (score of 3), a lot, a little, or not at all (score of 0). The DLQI score ranges from 0 (best) to 30 (worst); the higher the score, the more quality of life is impaired. A score \<6 indicates that psoriasis has small or no effect at all on participant's life.
