Other reasons
it was planned that study participation for each subject would be for a period of approximately one year, with 6 implants at intervals of 60 days. However, following highly encouraging results for interim data to Day 120 (after 2 implants), the study was terminated prematurely, to progress the investigation of this product in a multi-centre study (CUV017).
