PRIMARY outcome

Timeframe: Baseline and Week 6

Population: Per-Protocol (PP) 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 may have been a protocol violator in 1 treatment period and not in the other treatment period.

Serum LDL-C calculated using Friedewald formula at baseline and after 6 weeks of treatment in each of the 2 treatment periods.
