Brief Summary:
This study will represent the sponsor's first controlled study of etanercept in Chinese subjects with Ankylosing Spondytitis (AS). This trial is designed to assess the safety and efficacy of etanercept compared to placebo in the treatment of patients with AS.

Condition or disease Intervention/treatment Phase
Ankylosing Spondylitis Drug: Enbrel (etanercept) Phase 3

Detailed Description:
Multicenter, double-blind, randomized, parallel and placebo-controlled outpatient study. The study consists of 2 parts: part A is a 6-week double-blind treatment period and part B is a 6-week open-label treatment period. During part A of the study, subjects will be randomly assigned to 1 of 2 treatment regimens: 2 etanercept 25 mg or placebo once weekly, administered subcutaneously (SC). After the completion of part A, all subjects will receive 2 etanercept 25 mg once weekly. The use of placebo as a control in part A is necessary to allow a valid comparison and to provide a quantitative assessment of effect.
