Study Arms:
- TAK-085 4g (Type: EXPERIMENTAL): A dose of 2 g of omega-3-acid ethyl esters (TAK-085) capsule is orally administered immediately after meal twice a daily (totally 4g per a day) for 8 weeks, plus a stable HMG-CoA reductase inhibitor regimen (started ≥4 weeks prior to informed consent) at a consistent dose.
- Control Group (Type: EXPERIMENTAL): Stable HMG-CoA reductase inhibitor regimen at a consistent dose only.

Based on this trial design, predict the completion outcome and termination type (if applicable).
