Detailed Description:
The total duration of study for each subject is up to 15 weeks including a screening period up to 3 weeks.

Ages Eligible for Study:   18 Years to 65 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Serum LDL-C levels>100 mg/dL at screening visit.
  • Male or female subject, between 18 and 65 years inclusive.
  • Body weight between 50.0 and 95.0 kg inclusive if male, between 40.0 kg and 85.0 kg inclusive if female, body mass index (BMI) between 18.0 and 30.0 kg/m² inclusive.
