Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial

In compliance with EU regulations, the ‘end of the study’ is defined as the last patient’s last visit (LPLV).
End of study will be either the visit (± 7 days) at which Overall Response is computed as ‘progressive disease’ or the last visit, for those patients who drop out for other reasons or the Month 6 visit, for those patients in whom progressive disease is not diagnosed before Month 6. |
