245 sites January 2007 to July 2010

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Prior to randomization, each participant received simvastatin 40mg daily; if this dose was not as effective as their prior statin treatment or their total cholesterol was ≥135 mg/dl after 4 weeks on simvastatin alone, ezetimibe 10mg daily was added. Participants then received ERN/LRPT 1g/20mg daily for 4 weeks followed by 2g/40mg daily for 4 weeks.

Reporting Groups

Limitations and Caveats
Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Participants may have SAEs reported in >1 category hence total participants affected across reported categories is less than total given.
