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.

  20. Percentage of Participants Who Experience at Least 1 Clinical Adverse Event (AE)

    An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which was temporally associated with the use of the product, was also an AE. A clinical AE was an AE reported as a result of a clinical examination or reported by the participant.

    Measured: up to 14 weeks

  21. Percentage of Participants Who Experience at Least 1 Laboratory Adverse Event (AE)

    An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which was temporally associated with the use of the product, was also an AE. A laboratory AE was an AE reported as a result of a laboratory assessment or test.

    Measured: up to 14 weeks

  22. Percentage of Participants Who Were Discontinued From the Study Due to a Clinical AE

    An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which was temporally associated with the use of the product, was also an AE. A clinical AE was an AE reported as a result of a clinical examination or reported by the participant. Participants who were discontinued from the study due to a clinical AE were recorded.

    Measured: up to 14 weeks

  23. Percentage of Participants Who Were Discontinued From the Study Due to a Laboratory AE

    An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which was temporally associated with the use of the product, was also an AE. A laboratory AE was an AE reported as a result of a laboratory assessment or test. Participants who were discontinued from the study due to a laboratory AE were recorded.

    Measured: up to 14 weeks

  24. Percentage of Participants Who Experience at Least 1 Hepatitis-related Clinical AE

    An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which was temporally associated with the use of the product, was also an AE. Hepatitis-related AEs were identified by a collective review using the following pre-specified set of preferred terms: cholestasis, hepatic necrosis, hepatocellular damage, cytolytic hepatitis, hepatitis, hepatomegaly, jaundice, hepatic failure, hepatitis cholestatic, jaundice cholestatic, hepatitis fulminant, hyperbilirubinaemia, jaundice hepatocellular, ocular icterus, yellow skin, hepatic function abnormal, acute hepatic failure, subacute hepatic failure, hepatitis acute, hepatitis toxic, hepatotoxicity, and mixed hepatocellular-cholestatic injury.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing MK-0524A, Atorvastatin and Simvastatin in people with Mixed Hyperlipidemia, 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 1 inclusion and 5 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 31 Aug 2018. 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 26 Jan 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 the LDL-C/HDL-C Ratio (time frame: Baseline and Week 12). 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 NCT00289900, 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 31 Aug 2018.
