Clinically significant and sustained improvement in BASDAI
BASDAI absolute value over time to Week 104 (MI)1*
The open-label extension had limitations due to a lack of comparator past Week 16 and the use of select study populations that were more likely to show a drug effect.
Baseline BASDAI, mean (SD): 6.9 (1.2) in BIMZELX 160 mg Q4W patients vs 6.7 (1.3) in placebo patients.2
Missing data imputed using multiple imputation (MI); randomized set not adjusted for multiplicity; secondary endpoint; nominal P value.
BASDAI measures disease activity based on 5 key patient-reported outcomes3,4:
BASDAI ≥4=active disease.
Clinically significant and sustained nocturnal spinal pain relief
Nocturnal spinal pain absolute value over time to Week 104 (MI)1 *
The open-label extension had limitations due to a lack of comparator past Week 16 and the use of select study populations that were more likely to show a drug effect.
Baseline nocturnal spinal pain, mean (SD): 6.9 (2.0) in BIMZELX 160 mg Q4W patients vs 6.7 (2.1) in placebo patients.2
Missing data imputed using multiple imputation (MI); randomized set not adjusted for multiplicity; other efficacy endpoint; nominal P value.
Clinically significant and sustained total spinal pain relief
Total spinal pain absolute value over time to Week 104 (MI)1*
The open-label extension had limitations due to a lack of comparator past Week 16 and the use of select study populations that were more likely to show a drug effect.
Baseline total spinal pain, mean (SD): 7.3 (1.5) in BIMZELX 160 mg Q4W patients vs 7.1 (1.6) in placebo patients.2
Missing data imputed using multiple imputation (MI); randomized set not adjusted for multiplicity; other efficacy endpoint; nominal P value.
Clinically significant and sustained morning stiffness relief
Morning stiffness (BASDAI Q5 & Q6) absolute value over time to Week 104 (MI)1 *
The open-label extension had limitations due to a lack of comparator past Week 16 and the use of select study populations that were more likely to show a drug effect.
Baseline morning stiffness (mean of BASDAI questions 5 and 6), mean (SD): 7.0 (1.8) in BIMZELX 160 mg Q4W patients vs 6.9 (1.6) in placebo patients.2
Missing data imputed using multiple imputation (MI); randomized set not adjusted for multiplicity; secondary endpoint; nominal P value.
Sustained improvement in fatigue
FACIT-F absolute value over time to Week 104 (MI)1*
The open-label extension had limitations due to a lack of comparator past Week 16 and the use of select study populations that were more likely to show a drug effect.
Baseline FACIT-F score, mean (SE): 29.5 (0.9) in BIMZELX 160 mg Q4W patients vs 30.6 (1.0) in placebo patients.1
Missing data imputed using multiple imputation (MI); randomized set not adjusted for multiplicity; other efficacy endpoint; nominal P value.
BASDAI=Bath Ankylosing Spondylitis Disease Activity Index; CfB=change from baseline; FACIT-F=Functional Assessment of Chronic Illness Therapy-Fatigue; MI=multiple imputation; Q4W=every 4 weeks; SD=standard deviation; SE=standard error.
