About this study

Official title: A Phase III Confirmatory Study of K-877 (Pemafibrate) in Patients With Hypercholesterolemia and Statin Intolerance-Multicenter, Placebo Controlled, Randomized, Double Blind, Parallel Group Controlled Trial in Patients With Statin Intolerant Hypercholesterolemia-

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.

Being tested
K-877 0.2 mg/day (once daily), K-877 0.4 mg/day (once daily), Placebo (once daily)

What is being measured

The primary outcome is the main question the study is designed to answer.

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

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

    Measured: 4, 8, and 12 weeks after administration

Secondary outcomes (6)
  1. Efficacy: % change from baseline in fasting serum LDL-C (mg/dL)(Direct)

    Measured: 4, 8, and 12 week after administration

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

    Measured: 4, 8, and 12 week after administration

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

    Measured: 4, 8, and 12 week after administration

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

    Measured: 4, 8, and 12 week after administration

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

    Measured: 4, 8, and 12 week after administration

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

    Measured: 4, 8, and 12 week after administration

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing K-877 0.2 mg/day (once daily) and K-877 0.4 mg/day (once daily) in people with Hypercholesterolemia, run by Kowa Company, Ltd. at 22 sites in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 22 sites in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percent change from baseline in LDL-C (formula F). (time frame: 4, 8, and 12 weeks after administration). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Dec 2025.
