E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint is the proportion of subjects achieving clinical response defined as reduction in BVASv3 ≥ 50% at Week 16 compared to baseline and no worsening in any body system. Subjects who receive rescue therapy until Week 16 will be considered as not having achieved clinical response. |

|
E.5.2 | Secondary end point(s) |
