Inclusion criteria

• diagnosis of primary hypercholesterolemia (heterozygous familial and nonfamilial) Fredrickson types IIa or IIb.
• history of statin-associated myalgia, as defined by being unable to tolerate two previous statins due to muscle pain, aches, weakness, or cramping that begins or increases during statin therapy and stops when statin therapy is discontinued. History of statin-associated myalgia will be captured on the historical questionnaire on statin-associated myalgia.
• LDL-C > 110 mg/dL and triglycerides < 500 mg/dL at Prescreening.
• prescreening hemoglobin value of ≥10 g/dL for females and ≥12 g/dL.
• patient agrees to stop all other antihyperlipidemic agents (including but not limited to niacin, probucol, ezetimibe, fibrates and derivatives, bile acid-sequestering agents, other 3-hydroxy-3-methylglutaryl-coenzyme A(HMG-CoA) reductase inhibitors, fish oils, flaxseed oil, and red yeast rice).
• patient agrees to stop all Coenzyme Q10 supplements.
• if taking other nonexcluded medications, patients must be on a stable dose for 4 weeks before screening.

Exclusion criteria

• history of chronic pain and currently experiences chronic pain unrelated to statins that requires chronic use of pain medications, has been diagnosed with fibromyalgia or has severe neuropathic pain.
• requires the chronic use of pain medications, including acetaminophen, non-steroidal anti-inflammatory medications, narcotics, and other analgesics.
• vitamin D insufficiency (current insufficiency is defined as Vitamin D3 < 20 ng/mL [50 nmol/L] measured at Prescreening.
• hypothyroidism or abnormal thyroid function test as confirmed by thyroid-stimulating hormone ≥ 5 mcIU/mL and free thyroxine (T4) < 0.7 ng/dL at Prescreening
• history of rhabdomyolysis (defined as evidence of organ damage with creatinine kinase(CK) > 10,000 IU/L).
• history of liver disease
• history of significant renal dysfunction as defined by serum creatinine clearance < 30 mL/min
• Nephrotic-range proteinuria.
• HbA1C >9% at Prescreening.
• CK levels >5 times the upper limit of normal at Prescreening.
• congestive heart failure, even with current therapy
• has had myocardial infarction, cardiac intervention, cerebrovascular accident/stroke or transient ischemic attack less than 6 months prior to prescreening.
• patient is pregnant (confirmed by laboratory testing) or breastfeeding.
• history of cancer (other than basal cell and/or squamous cell carcinoma of the skin and/or Stage I squamous cell carcinoma of the cervix) that has not been in full remission for at least 1 year before Screening.
