Clinical Trial Summary

The purpose of this study is to evaluate the effect of treatment withdrawal compared to continued treatment with golimumab (GLM) administered by subcutaneous (SC) injection on the incidence of a "flare" in non-radiographic axial spondyloarthritis over up to 12 months. The primary hypothesis is that continued treatment with golimumab is superior to treatment withdrawal, based on the percentage of subjects without a "flare" during up to 12 months of blinded therapy.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Percentage of Participants Without a Disease Activity Flare During Period 2 (Full Treatment Regimen Versus Withdrawal Regimens)	Disease flare is defined as an Ankylosing Spondylitis Disease Activity Score (ASDAS) at two consecutive visits that both show either absolute score =2.1 or a post-withdrawal increase of =1.1 relative to baseline prior to the first dose of double-blind treatment in Period 2. The ASDAS is a composite index assessing disease activity in axial spondyloarthropathies that consists of 4 self-assessed parameters and 1 laboratory parameter. The self-assessed parameters of back pain, duration of morning stiffness, Patient Global Disease Assessment (PGDn), and peripheral pain/swelling are individually scored on a numeric scale of 0 to 10, with 0 being low activity/impact and 10 being high activity/impact. The self-assessed criteria and the laboratory value of CRP are combined to provide the total ASDAS score, which has a lower limit of 0.6 and no defined upper limit. A higher score indicates greater disease activity.	Up to 12 months

A higher score indicates greater disease activity.	Up to 12 months
Secondary	Percentage of Participants With a Flare Who Show a Clinical Response Within 3 Months of Open-Label Golimumab Retreatment	Clinical response is defined as Bath Ankylosing Spondylitis Disease Assessment Index (BASDAI) score improvement of =2.0 or =50% improvement within 3 months of the start of retreatment, relative to the mean of the two consecutive BASDAI scores that defined the flare. Sustained clinical response refers to participants who attained clinical response and maintained BASDAI criteria throughout the 3-month retreatment period. Response data was collected throughout Period 2 (12 months) and censored to include only the first 3 months after retreatment for a disease flare. The BASDAI is a summary of 6 participant-assessed measures rated on scales of 0 (none) to 10 (very severe): fatigue, spinal pain, joint pain/swelling, tenderness, morning stiffness, and duration of morning stiffness [0 (zero) to 10 (2 or more hours)]. The BASDAI score is the mean of responses to the 6 questions with a minimum of 0 and a maximum of 10. A higher score indicates greater disease activity.	Up to 3 months following start of retreatment
Secondary	Time to First Disease Flare	The Kaplan-Meier analysis of time to first "flare" in Period 2 is represented by the percentage of participants who experienced a disease flare relative to baseline prior to the first dose of double-blind treatment in Period 2.

Secondary	Percentage of Participants Who Experienced an Adverse Event (AE) in Period 2	This endpoint evaluated the safety and tolerability of withdrawing from or continuing treatment with golimumab in Period 2. An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a study treatment and which does not necessarily have to have a causal relationship with this treatment. An AE could be any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a study treatment, whether or not considered related to the study treatment. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of study treatment, is also an AE. The analysis includes AEs that occurred through 90 days after the last dose of study treatment.	Up to approximately 15 months
Secondary	Percentage of Participants Who Discontinued Study Treatment Due to an AE in Period 2	This endpoint evaluated the safety and tolerability of withdrawing from or continuing treatment with golimumab in Period 2. An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a study treatment and which does not necessarily have to have a causal relationship with this treatment. An AE could be any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a study treatment, whether or not considered related to the study treatment. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of study treatment, is also an AE.	Up to approximately 12 months
