Further study details as provided by Lawson Health Research Institute:

Primary Outcome Measures:
  • To assess the reliability and reproducibility of subjective symptoms of myalgias to active statin therapy. [ Time Frame: Duration of study September 2010 to August 2013 ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To delineate the relation of objective changes in non-invasive neuromuscular testing to subjective symptoms during the first exposure to active or placebo therapy, in subset of 5 patients with prior history of statin myopathy. [ Time Frame: September 2010 to August 2013 ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 10
Study Start Date: September 2010
Estimated Study Completion Date: August 2013
Estimated Primary Completion Date: August 2013 (Final data collection date for primary outcome measure)
