Clinical Trial Summary

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.

Secondary	Percentage of Participants With New Diagnosis of Impaired Fasting Blood Glucose	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). 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.	up to 12 weeks
Secondary	Percentage of Participants With New Diagnosis of Diabetes	Participants had blood glucose levels assessed throughout the 12 week treatment period. Participants who with newly diagnosed of diabetes were recorded. 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.	up to 12 weeks

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.	up to 14 weeks

Secondary	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.	up to 14 weeks
