Intervention model description
PART 1: Total duration of Part 1 is 27 months. The randomized double-blind placebo-controlled period ranges from 15 to 27 months depending upon the randomization date of an individual patient. Once the last month 15 evaluation of the study has been completed, patients will switch to the active drug at the next planned visit. Participants and study personnel will remain blinded as to the original treatment assignment. Maximum duration of double-blind period per patient will be no longer than 27 months. PART 2: At the last evaluation of Part 1 (Visit 11/Month 27) all participants will be offered active treatment in an open label extension for 39 additional months (From V11/M27 to V18/M66). The purpose of the active drug extension is to further define the safety of MD1003.
