About this study

Official title: A Placebo-controlled, Double-blind, Randomized Trial to Evaluate the Effect of Different Doses of Inclisiran Given as Subcutaneous Injections in Japanese Participants With High Cardiovascular Risk and Elevated LDL-C

This was a placebo-controlled, double-blind, randomized trial in Japanese participants with history of coronary artery disease (CAD) or participants categorized in 'high risk' by JAS 2017 guideline, or Japanese participants with heterozygous familial hypercholesterolemia (HeFH) and elevated Low-density lipoprotein cholesterol (LDL-C) despite maximum tolerated dose of statin(s) to evaluate the efficacy, safety, tolerability, and PK of subcutaneous inclisiran injection(s).

Read the detailed description

The expected duration of the participants' involvement in the study was approximately 374 days which included screening (up to 14 days), Day 1 study drug administration, two additional injections on Day 90 and Day 270, and the follow-up period to Day 360.

The primary analysis was conducted after all participants had finished Day 180 visit assessments or discontinued before Day 180 visit.

After the primary analysis, double-blind treatment period were maintained to Day 360, although specific sponsor members (except for blinded monitors) were unblinded for the regulatory submission in Japan.

What is being measured

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

  1. Percent Change From Baseline in Low-density Lipoprotein Cholesterol (LDL-C) to Day 180

    Percent change from baseline in LDL-C was calculated to evaluate the effect of inclisiran at Day 180.

    Difference between different inclisiran dose groups and the placebo group in percentage change in LDL-C levels from baseline to Day 180 were calculated to capture both, the effect of the study drug and the effect of additional medications, mirroring the conditions in clinical practice.

    An MMRM (Mixed-effect Model with Repeated Measurement) was used as the primary analysis model, with treatment group, visits, interaction between visits and treatment groups, current use of statins or other lipid-modifying therapies as fixed effects, and baseline LDL-C as a continuous covariate.

    Measured: Baseline, Day 180

A Phase 2 study testing Inclisiran sodium in people with Hypercholesterolemia and Heterozygous Familial Hypercholesterolemia, run by Novartis Pharmaceuticals at 42 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?

The sponsor lists 5 inclusion and 7 exclusion criteria. 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 20 Jun 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 42 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 May 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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 Low-density Lipoprotein Cholesterol (LDL-C) to Day 180 (time frame: Baseline, Day 180). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04666298, which also lists 1 linked publication.

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 20 Jun 2024.
