Study summary

To investigate the efficacy and safety of K-877 Extended Release 0.2 mg/day or 0.4 mg/day for 12 weeks in patients with Statin Intolerant* Hypercholesterolemia,using placebo as a controll.

*Statin Intolerant: Adverse events associated with statin use that cause unacceptable disturbances in the user's daily life, resulting in drug discontinuation or dose reduction.

What researchers measure

Primary outcomes

  1. Percent change from baseline in LDL-C (formula F).

    Percent change = (measured value at each time point - baseline value) / baseline value

    Time frame: 4, 8, and 12 weeks after administration

Secondary outcomes

  1. Efficacy: % change from baseline in fasting serum LDL-C (mg/dL)(Direct)

    Time frame: 4, 8, and 12 week after administration

  2. Efficacy: % change from baseline in fasting serum HDL-C (mg/dL)

    Time frame: 4, 8, and 12 week after administration

  3. Efficacy: % change from baseline in fasting serum non HDL-C (mg/dL)

    Time frame: 4, 8, and 12 week after administration

  4. Efficacy: % change from baseline in fasting serum TG (mg/dL)

    Time frame: 4, 8, and 12 week after administration

  5. Efficacy: % change from baseline in fasting serum LDL-C(formula F)/HDL-C

    Time frame: 4, 8, and 12 week after administration

  6. Efficacy: % change from baseline in fasting serum non HDL-C/HDL-C

    Time frame: 4, 8, and 12 week after administration
