Summary
Combination Methotrexate and Infliximab: Influence of immunogenicity on the efficacy of
infliximab in patients with Ankylosing Spondylitis.
Clinical Details
Official title: The Efficacy of Combination Methotrexate and Infliximab in Patients With Ankylosing Spondylitis:A Clinical and Magnetic Resonance Imaging Correlation
Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment
Primary outcome: The number of patient exhibited an ASAS 20 response to treatment at week 20.
Secondary outcome: Proportion of patients with 50% and 70% improvement in disease activity.Patient global assessment of disease activity and pain;BASFI;early morning stiffness;physician global assessment of disease activity.Changes in the pre and post infusion MRI.
Detailed description:
Forty consecutive patients will be recruited from the rheumatology clinic of the Prince of
Wales Hospital with AS meeting the modified New York criteria with active disease as defined
(see below). They will be randomized to receive MTX 7. 5 mg/week initially with a weekly
2. 5mg increment until 15mg/week dosage is reached,( i. e by week 6) or a placebo together
with folic acid 5mg daily for a period of 16 week. After 16 weeks, all patients will receive
infliximab at 5 mg/kg per dose, at weeks 16, 18, and 22 (3 doses), and will continue with
MTX 15 mg/week or placebo. Thereafter, they will be followed up at week 30, 38 weeks. MRI
changes in the sacroiliac joints (SI) before and after infliximab treatment.
