TAVNEOS-based regimen resulted in a lower absolute risk of relapse vs a GC-based regimen over 52 weeks1
Absolute risk of relapse over 52 weeks of treatment1
Twice as many patients relapsed in the GC-based regimen vs the TAVNEOS-based regimen1
There was no pre-speci ed plan for adjustment of con dence intervals for multiplicity of the secondary end points; point estimates and 95% con dence intervals only are presented, and no de nite conclusions can be drawn from these data
Relative risk of relapse
TAVNEOS-based regimen demonstrated a 54% relative risk reduction in relapse vs a GC-based regimen over 52 weeks1
ADVOCATE study design
52 week, international, multicentre, active-comparator, randomised, double-blind, double-dummy, controlled, pivotal phase 3 study with patients assigned to receive TAVNEOS 30 mg twice daily (N=166) or prednisone tapering schedule for 20 weeks (60 mg per day tapered to discontinuation by Week 21) (N=164) on the top of either cyclophosphamide (followed by azathioprine) or rituximab.1
TAVNEOS-based regimen patients received NO study-supplied GCs. Patients in both regimens could use non-study supplied GCs throughout the 52-week study at their physician’s discretion for AAV worsening or non-AAV-related reasons. Non-study supplied GCs during the screening had to be tapered to ≤20 mg per day before entering the study, and further tapered to 0 mg by the end of Week 4 of the study.5

*Clinical remission in the ADVOCATE study was defined as a BVAS 0 and no glucocorticoid use in previous 4 weeks.1
The NNT was calculated using https://www.statology.org/confidence-interval-difference-in-proportions-calculator/ to determine the confidence intervals for crude difference in proportions. At Week 52, the response rates were 65.7% in the TAVNEOS-based regimen and 54.9% in the GC-based regimen. This led to a crude result of NNT = 1/(0.657-0.549) = 9.26, rounded to 10 patients. Using the adjusted model and the estimated common difference, the NNT = 1/0.125 = 8. In conclusion, the NNT is between 8 and 10 patients at Week 52.1
‡A numerical improvement was seen in mental QoL.6
§With the EQ-5D-5L index, numerical improvements were observed at Week 26, and significant improvements were observed at Week 52 (p=0.009) in the TAVNEOS-based regimen vs GC-based regimen.6
