Limitations and Caveats
Due to change in planned analysis, safety data for main study and LTE were combined for Groups 1 and 2 as LTE was a follow up for the participants who were in main study in Groups 1 and 2 and no intervention was given in LTE. As both phases involved the same participants in continued monitoring, the data reflects ongoing safety assessment.
