This is an open-label, multicenter and observational study in China, which is designed to
record the data of RA & AS patients within 52 weeks after rheumatologists decided to
prescribe etanercept, and evaluate the safety and efficacy of the treatment. All eligible
subjects agreed to be recruited in the study and can withdraw anytime if they choose so.
Patients with RA or AS are typically managed by rheumatologists. As this study seeks to
record the data of RA & AS patient in etanercept and evaluate the safety and efficacy of the
treatment, patients will be recruited from Rheumatic department. Rheumatologist will be
asked to build up the database for RA & AS patient surveillance prospectively in outpatient
dept, which benefits for the patient treatment outcomes evaluation and clinical management.
Official title: A Non-Interventional Study of the Treatment With Etanercept in Rheumatoid Arthritis (RA) and Ankylosing Spondylitis (AS) Subjects in Rheumatology Department
Study design: Observational Model: Case Control, Time Perspective: Prospective
Primary outcome: To evaluate the safety of etanercept in real clinical practice in Chinese RA and AS subjects by measuring the number of subjects reporting an event
To evaluate the efficacy of etanercept in Chinese RA and AS subjects by comparing Disease Activity Score Using 28-Joint Count (DAS28)
To evaluate the efficacy of etanercept in Chinese RA and AS subjects by comparing the Physician Global Assessment (PGA) of Disease Activity on 0-100 mm visual analog scale (VAS)
To evaluate the efficacy of etanercept in Chinese RA and AS subjects by comparing the Pain assessment 0-100 mm visual analog scale (VAS)
To evaluate the subject's adherence to treatment in real-life by comparing patient's dosage and frequency with label use (25 mg biweekly, or 50 mg weekly)
To evaluate the association between subject's age and treatment adherence by comparing grouped adherence
The primary objective of this non-interventional study is to evaluate the safety of
etanercept in Chinese RA and AS subjects. Total of 600 subjects (300 RA subjects and 300 AS
subjects) will be enrolled in the study. If the true rate of an adverse event is no less
than 0. 5%, with sample size of 600 subjects, this study will have 95% probability to detect
at least one occurrence of the adverse event.
Minimum age: 18 Years.
Maximum age: N/A.
- Subject has a confirmed diagnosis of rheumatoid arthritis or ankylosing spondylitis.
- Subject has accepted physician's prescription of etanercept in rheumatology
- Subject agreed to be enrolled in the observational study and sign the ICD.
- Subject is≥18 years of age at the time of consent.
- Subject is willing and able to understand and complete questionnaires
- Presence of active or suspected latent infection including HIV, or any underlying
disease, including open cutaneous ulcers that could predispose the subject to
- Immunodeficiency syndromes including Felty syndrome or large granular lymphocyte
- Active tuberculosis (TB) or a history of TB, or findings consistent with previous
exposure to TB on a chest x-ray (CXR). Investigators must follow China's guidelines
for appropriate screening and treatment of TB.
- History of hypersensitivity to any of the ingredients in either preparation.
