Participants had blood glucose levels assessed throughout the 12 week treatment period. 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).

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

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
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.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a 12-week clinical trial in participants with mixed hyperlipidemia to study the effects of MK-0524B on lipids.The primary hypothesis is that MK-0524B (dosed as MK-0524A coadministered with simvastatin) will be superior to atorvastatin on decreasing the low denisity lipoprotein cholesterol (LDL-C)/high-density lipoprotein cholesterol (HDL-C) ratio for the following dose comparisons: 2g/20 mg MK-0524B versus 10 mg atorvastatin, 2g/40 mg MK-0524B versus 20 mg atorvastatin, 2g/40 mg MK-0524B versus 40 mg atorvastatin, and 2g/40 mg MK-0524B versus 80 mg atorvastatin.

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.
