Percentage of Participants With Any Adverse ExperienceFrom start of treatment through 14 days after the last dose (Up to 26 weeks)An adverse event was any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study drug, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which was temporally associated with the use of the study drug, was also an adverse event.

Participant flow

Recruitment details

1,166 participants who were currently using niacin (+) laropiprant (TREDAPTIVE) for treatment of primary hypercholesterolemia or mixed dyslipidemia were enrolled and their case report forms were collected. Enrollment was stopped early due to termination of all studies involving TREDAPTIVE.

Pre-assignment details

A completer was considered a participant eligible for safety population. Efficacy population was a sub-population of the safety population
