PRIMARY outcome

Timeframe: Baseline and Week 6

Population: Per-Protocol Population, which excluded participants due to important deviations from the protocol that may have substantially affected the results of the primary efficacy endpoint(s). A participant could be excluded from 1 or more of the analyses. Results are reported by treatment formulation and not by sequence.
