Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
For administrative and safety reporting purposes, the end of the trial will be defined as the date of the final clinical database lock after the last subject has completed the Week 48/96/Early Termination visit and the safety follow-up visit 12 weeks after, at Week 108. This provides for a single and conservative definition across all trial sites. |
