What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants With Axial Spondyloarthritis International Society 40% Response Criteria (ASAS40) at Week 12
The ASAS40 response was defined as relative improvements of at least 40% and absolute improvement of at least 2 units on a 0 to 10 Numeric Rating Scale (NRS), where 0 is "not active" and 10 is "very active" in at least 3 of the 4 domains: Patient's Global Assessment of Disease Activity (PGADA), Pain assessment (total spinal pain NRS score), Function (Bath Ankylosing Spondylitis Functional Index (BASFI)), Inflammation (mean of Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) questions 5 and 6 concerning morning stiffness intensity and duration) and no worsening at all in the remaining domain.
Note: Participants with missing data or who discontinue study treatment prior to Week 12 were counted as non-responders.
Measured: Week 12
Secondary outcomes (8)
Change From Baseline in Ankylosing Spondylitis Disease Activity Score - C-Reactive Protein (ASDAS [CRP]) at Week 12
The ASDAS was calculated as the sum of the following components:
0.121 x Back pain (BASDAI question 2 result) 0.058 x Duration of morning stiffness (BASDAI question 6 result) 0.110 x PGADA 0.073 x Peripheral pain/swelling (BASDAI question 3 result) 0.579 x (natural logarithm of the (hs-CRP [mg/L] + 1)) Back pain, PGADA, duration of morning stiffness, peripheral pain/swelling and fatigue are all assessed on a numerical scale (0 to 10 units).
The change from Baseline is calculated, a negative value indicating improvement and a positive value worsening. There is a minimum score of 0.636 for the total ASDAS score, but no defined upper score since CRP does not have a set upper limit.
If one component for the ASDAS-CRP was missing at a given visit, that component was imputed by carrying the last observation forward, and the ASDAS-CRP was calculated accordingly. If the hs-CRP value was below 2 mg/L, then it was imputed as the constant value of 2 mg/L.
Measured: From Baseline to Week 12
Percentage of Participants With Axial Spondyloarthritis International Society 20% Response Criteria (ASAS20) at Week 12
The ASAS20 response was defined as an improvement of at least 20% and absolute improvement of at least 1 unit on a 0 to 10 NRS, where 0 is "not active" and 10 is "very active" in at least 3 of the 4 domains: PGADA, Pain assessment (total spinal pain NRS scores), Function (BASFI), Inflammation (mean of BASDAI questions 5 and 6 concerning morning stiffness intensity and duration) and absence of deterioration in the potential remaining domain [deterioration was defined as a relative worsening of at least 20% and an absolute worsening of at least 1 unit].
Note: Participants with missing data or who discontinue study treatment prior to Week 12 were counted as non-responders.
Measured: Week 12
Percentage of Participants With Axial Spondyloarthritis International Society (ASAS) 5/6 Response at Week 12
The ASAS 5/6 response was defined as at least 20% improvement in at least 5 of the 6 domains: PGADA, Pain assessment (total spinal pain NRS scores), Function (BASFI), Inflammation (mean of BASDAI questions 5 and 6 concerning morning stiffness intensity and duration), spinal mobility (lateral spinal flexion) and high sensitivity C-reactive protein (hs-CRP).
Note: Participants with missing data or who discontinue study treatment prior to Week 12 were counted as non-responders.
Measured: Week 12
Change From Baseline to Week 12 in the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)
The BASDAI is a validated self-reported instrument, which consists of six 10-unit horizontal Numeric Rating Scales (NRS) to measure severity of fatigue, spinal and peripheral joint pain and swelling, enthesitis, and morning stiffness (both severity and duration, respectively) over the last week. The final BASDAI score ranges from 0 to 10, with lower scores indicating lower disease activity.
The change from Baseline is calculated, a negative value indicating improvement and a positive value worsening.
Note: Missing data was imputed using multiple imputation based on the Markov-Chain Monte Carlo method for the intermittent missing data, followed by monotone regression for the monotone missing data assuming missing at random.
Measured: From Baseline to Week 12
Change From Baseline to Week 12 in the Bath Ankylosing Spondylitis Functional Index (BASFI)
The BASFI is a validated disease-specific instrument for assessing physical function. The BASFI comprises 10 items relating to the past week. The BASFI is the mean of the 10 scores such that the total score ranges from 0 (Easy) to 10 (Impossible), with lower scores indicating better physical function.
The change from Baseline is calculated, a negative value indicating improvement and a positive value worsening.
Note: Missing data was imputed using multiple imputation based on the Markov-Chain Monte Carlo method for the intermittent missing data, followed by monotone regression for the monotone missing data assuming missing at random.
Measured: From Baseline to Week 12
Percentage of Participants With at Least One Adverse Event (AE) During the Study
An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.
Measured: From Screening until Safety Follow-Up Visit (up to Week 77)
Percentage of Participants With at Least One Serious Adverse Event (SAE) During the Study
A serious adverse event (SAE) is any untoward medical occurrence that at any dose:
- Results in death
- Is life-threatening
- Requires in patient hospitalisation or prolongation of existing hospitalisation
- Is a congenital anomaly or birth defect
- Is an infection that requires treatment parenteral antibiotics
- Other important medical events which based on medical or scientific judgement may jeopardise the patients, or may require medical or surgical intervention to prevent any of the above.
Measured: From Screening until Safety Follow-Up Visit (up to Week 77)
Percentage of Participants Who Withdrew Due to an Adverse Event (AE) During the Study
An AE is any untoward medical occurrence in a participant or trial subject that is administered a drug or biologic (medicinal product) or that is using a medical device.
The event does not necessarily have a causal relationship with that treatment or usage. The results of this Secondary Outcome Measure were summarized from the adverse event pages of the Case Report Forms.
Measured: From Screening until Safety Follow-Up Visit (up to Week 77)

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of Participants With Axial Spondyloarthritis International Society 40% Response Criteria (ASAS40) at Week 12 (time frame: Week 12). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02963506, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
