A Post-Marketing-Observational Study (PMOS) to Determine the Effectiveness of Combined Adalimumab Treatment and Active Supervised Training in Patients With Axial Spondyloarthritis (axSpA)

AbbVie17 enrolled

Overview

This study is a non-interventional, longitudinal and non-confirmatory study to compare an active supervised training (AST) with standard of care (SOC) physiotherapy in patients with axial spondyloarthritis and stable response to adalimumab (HUMIRA®) with respect to health-related outcomes. The primary objective is the improvement in spinal mobility after a 6 month training program.

Treatment of axSpA patients with adalimumab (HUMIRA®) was according to the local adalimumab product label and local standard of care. AxSpA patients who responded to newly initialized adalimumab treatment based on physicians' decision, and who were eligible for active physiotherapy were enrolled in the study. Although this was a non-interventional study, participants were randomly assigned to receive either active supervised and standardized training physiotherapy or standard of care physiotherapy in order to provide adequate numbers of participants in each comparison group. Participants who consented to participate in the study were observed for up to 12 months from Baseline (defined as the Randomization visit where participants were assigned to one of the two physiotherapy options).

Outcomes

Primary Outcomes

Change Form Baseline in Bath Ankylosing Spondylitis Metrology Index (BASMI) at Month 6

BASMI measures the range of motion based on five clinical measurements: 1) cervical rotation, 2) tragus to wall distance, 3) lumbar side flexion, 4) lumbar flexion (modified Schober's) and 5) intermalleolar distance. The total BASMI score ranges from 0 to 10 reflecting mild to moderate disease activity and functional ability in the spinal column. The higher the BASMI score the more severe the patient's limitation of movement due to their ankylosing spondylitis

Time frame: Baseline and Month 6

Secondary Outcomes

Change Form Baseline in Bath Ankylosing Spondylitis Metrology Index (BASMI) at Month 3

Time frame: Baseline and Month 3

Change From Baseline in Bath Ankylosing Spondylitis Functional Index (BASFI)

The Bath Ankylosing Spondylitis Functional Index (BASFI) is a validated index to determine the degree of functional limitation in patients with AS. BASFI consists of 10 questions assessing participants' ability to perform activities, each on a numeric rating scale (NRS) ranging from 0 (easy to perform an activity) to 10 (impossible to perform an activity). The overall score is the mean of the 10 items and ranges from 0 to 10 with higher score indicating more limitations.

Time frame: Baseline and Month 3

Change From Baseline in Assessment of Spondyloarthritis International Society (ASAS) Health Index (HI)

The ASAS HI measures functioning and health across 17 aspects of health in patients with AS, including pain, emotional functions, sleep, sexual function, mobility, self care, and community life. The ASAS HI consists of 17 questions, each answered by the participant as agree (1) or disagree (0). The responses to the 17 dichotomous items are summed up to give a total score ranging from 0 to 17, with a lower score indicating a better and a higher score indicating an inferior health status.

Change From Baseline in the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)

The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) assesses disease activity by asking the participant to answer 6 questions (each on an 11 point numeric rating scale \[NRS\]) pertaining to symptoms experienced for the past week. For 5 questions (level of fatigue/tiredness, level of AS neck, back or hip pain, level of pain/swelling in joints, other than neck, back or hips, level of discomfort from any areas tender to touch or pressure, and level of morning stiffness), the response is from 0 (none) to 10 (very severe); for Question 6 (duration of morning stiffness), the response is from 0 (0 hours) to 10 (≥ 2 hours). The overall BASDAI score ranges from 0 to 10 where lower scores indicate less disease activity.

Time frame: Baseline and Month 3

Percentage of Participants Achieving a BASDAI 50 Response

The BASDAI assesses disease activity by asking the participant to answer 6 questions (each on an 11 point numeric rating scale \[NRS\]) pertaining to symptoms experienced for the past week. For 5 questions (level of fatigue/tiredness, level of AS neck, back or hip pain, level of pain/swelling in joints, other than neck, back or hips, level of discomfort from any areas tender to touch or pressure, and level of morning stiffness), the response is from 0 (none) to 10 (very severe); for Question 6 (duration of morning stiffness), the response is from 0 (0 hours) to 10 (≥ 2 hours). The overall BASDAI score ranges from 0 to 10. Lower scores indicate less disease activity. A BASDAI 50 response is defined as improvement of 50% or more from baseline in BASDAI score.
