    Participants had fasting glucose levels assessed during Period I (4 weeks ) throughout each 8 week treatment period (20 weeks total). Participants who had the new diagnosis of impaired fasting blood glucose were recorded. A pre-defined set of MedDRA terms was used to identify participants whose glycemic status became 'impaired' during the course of treatment (from clinical adverse experience reports). The MedDRA terms were as follows: blood glucose increased, blood glucose abnormal, glucose tolerance decreased, glucose tolerance test abnormal, carbohydrate tolerance decreased, glucose tolerance impaired, hyperglycaemia, impaired fasting glucose, impaired insulin secretion, metabolic syndrome, insulin resistance, insulin resistance syndrome.

    Measured: up 20 weeks (12 weeks in Period I/II and 8 weeks in Period III)

A participant was classified as having new onset diabetes if they experienced an adverse Event (AE) related to a diagnosis of diabetes (based on a pre-defined set of Medical Dictionary for Regulatory Activities [MedDRA] terms), or if they started taking an anti-diabetic medication during the course of the study. The MedDRA terms were as follows: diabetes mellitus, diabetes mellitus insulin-dependent, diabetes mellitus non-insulin dependent, insulin-requiring type II diabetes mellitus, insulin resistant diabetes, diabetes with hyperosmolarity, latent autoimmune diabetes in adults.

    Measured: up 20 weeks (12 weeks in Period I/II and 8 weeks in Period III)

  8. Percentage of Participants With Worsening of the Pre-existing Conditions of Diabetes in Participants With Diabetes at Baseline

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Comparator: simvastatin, MK-0524A and MK-0524B in people with Primary Hypercholesterolemia and Mixed Dyslipidemia, run by Merck Sharp & Dohme LLC.

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 4 inclusion and 4 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 6 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. 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?

Yes. Results are posted in the registry (first posted 1 Apr 2016). 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?

Percentage Change From Baseline in Low-density Lipoprotein Cholesterol (LDL-C) (time frame: Baseline (Week 4 for Period II; Week 12 for Period III) and after 8 weeks of treatment during each period (Week 12 for Period II and Week 20 for Period III)). 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 6 Feb 2019; AzTrials last refreshed its copy on 26 Oct 2026.
