Brief summary:
1PC002 is a newly developed synthetic and highly potent HMG-CoA reductase inhibitor. Its active compound, pitavastatin has recently been approved by US FDA for indications of primary hypercholesterolemia and combined dyslipidaemia. It exhibits unique pharmacokinetic properties. Unlike atorvastatin which is metabolized by CYP3A4, metabolism of 1PC002 does not depend on CYP3A4. This multi-center study is conducted to confirm the efficacy and safety of 1PC002 administered for 12 weeks is non-inferior to atorvastatin.

Detailed description:
This is a prospective, active-controlled, double-blind, randomized, parallel, and multi-center study. To target 150 evaluable subjects, approximately 200 Taiwanese patients with primary hypercholesterolemia or combined dyslipidemia will be enrolled in this study.

After providing the written inform consent, patients will undergo a complete physical examination, vital sign (brachial BP / HR), medical history, and lab assessment, including fasting serum LDL-C, TC, HDL-C, TG, and non-HDL. They should not take any hypolipidemic drugs for at least 4 weeks prior to initiation of study treatment. All eligible subjects will be randomized into 2 groups in a 1:1 ratio to receive either 2 mg 1PC002 or 10 mg atorvastatin once daily for 12 weeks.

* Study Group: 1PC002 1 cap. q.d. p.o.
* Control Group: Atorvastatin 1 cap. q.d. p.o.

After entering the baseline visit, lipid profiles (including fasting serum LDL-C, TC, HDL-C, TG, non-HDL, Apo A1, Apo B and Apo B / Apo A1 ratio), hs-CRP, eGFR, spot urinary albumin / creatinine ratio (ACR) and central BP values will be obtained at baseline, Week 4 and Week 12 for evaluating the effectiveness of study drugs and for any possible changes in laboratory data. Non-HDL value will be calculated by subtracting HDL-C from TC. Moreover, serum Cystatin C, another biomarker of renal function, will also be assessed at baseline and Week 12.

For monitoring the safety, biochemical and hematological assessment will be performed at baseline, Week 4 and 12. Additional liver function and CK test will be conducted at Week 8. The occurring AE(s) and SAE will be followed until resolution or the event is considered stable.

Arms:
arm 1: 2 mg 1PC002 once daily for 12 weeks. arm 2: 10 mg atorvastatin once daily for 12 weeks.

Interventions: intervention 1: 1PC002 intervention 2: Lipitor
Intervention descriptions: intervention 1: Subjects should be instructed to take 1 capsule of study drug (1PC002 or atorvastatin) orally once a day, with or without food. Administration before bedtime or at regular time-interval is recommended. intervention 2: Subjects should be instructed to take 1 capsule of study drug (1PC002 or atorvastatin) orally once a day, with or without food.
