Treatment arms will be initiated in parallel within each study part. Each participant will participate in only one treatment arm. After participants in Treatment Arms 1-3 (Study Part 1) will complete Week 9, the tolerability and, safety data through Week 9 will be reviewed by a safety review team. (Participants in arms 1-3 will continue in the study as the safety review is being completed.) Once the safety review for Arms 1-3 (Study part 1) will be completed and approved, Treatment Arms 4-6 (Study Part 2) will begin.
