E.5 End points |
E.5.1 | Primary end point(s) |
Treatment groups will be compared to measure the proportion of subjects reaching responder status. A subject will be considered a responder if he/she meets all the following criteria:
- Minimal Manifestations or Pharmacologic Remission (MGFA Postintervention Status definitions modified) from Week 32 until study termination at Week 36 and,
- Prednisone dose of not more than 7.5 mg/day from Week 32 until study termination at Week 36 and,
-Cholinesterase inhibitor dose of ≤120 mg/day from Week 33* until study termination at Week 36
*patients have one week to reduce cholinesterase inhibitor dose after reaching 7.5 mg/day prednisone |
