Primary Outcome Measures:
  • Treatment Response (using ASAS criteria) of at least 20% and absolute improvement of at least 10 units on a 0-100 scale in at least 3 of the 4 domains [ Time Frame: Up to 4 years ]
  • Absence of deterioration (using ASAS criteria) of at least 20% and absolute improvement of at least 10 units on a 0-100 scale in the potential remaining ASAS domain [ Time Frame: Up to 4 years ]

Secondary Outcome Measures:
  • DXA and MRI scans (at selected sites) [ Time Frame: Up to 144 weeks ]
  • X-rays of cervical spine and lumbosacral spine [ Time Frame: Up to 4 years ]
  • Type and grade of toxicities [ Time Frame: Up to 4 years ]
  • ASAS Response Criteria at weeks 24, 36, 48, 60, 72, 84, 96, 108, 120, and the ASAS Response Criteria at 50% and 70% levels at weeks 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, and 144. [ Time Frame: Up to 4 years ]
  • Frequency and time to partial remission as defined in Anderson, 2001: Value of <20 (on a scale of 0-100) in each of the following 4 domains: VAS Patient Global Assessment, VAS Pain Score, BASFI, and BASDAI morning stiffness-related scores [ Time Frame: Up to 4 years ]
  • Spinal mobility measured with Schober's test, chest expansion, and occiput to wall distance [ Time Frame: Up to 120 weeks ]
  • Complete joint assessment [ Time Frame: Up to 120 weeks ]
  • Laboratory assessment of inflammation using CRP [ Time Frame: Up to 120 weeks ]
  • Ability to reduce and discontinue concomitant NSAIDs, prednisone, hydroxychloroquine, sulfasalazine, and methotrexate [ Time Frame: Up to 4 years ]
