---|---|
Experimental: Sequence 1: MK-0524B 2g/40g→MK-0524A 2g + Simvastatin 40 mg
After a 2-week placebo run-in, participants received extended release (ER) niacin/laropiprant (N/LRPT) 1 g/20 mg combination tablet (MK-0524B) once daily for 4 weeks, then ERN/LRPT/Simvastatin (SIM) 2 g/40 mg combination tablet once daily for 8 weeks.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
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 (Week 12 for Period II and Week 20 for Period III)
|
Blood samples were taken at baseline (Week 4 for Period II; Week 12 for Period III) and after 8 weeks of treatment (Week 12 for Period II and Week 20 for Period III) to determine the LDL-C levels. The change from baseline after 8 weeks of treatment was recorded. Results from recent studies indicated that the combination tablet formulations used in the study did not meet the pre-specified pharmacokinetic bounds used to establish the equivalence of the combination tablet (MK-0524B; ERN/LRPT/SIM) to the coadministration of MK-0524A (ERN/LRPT) and SIM. Therefore, efficacy data were not analyzed, as the study was stopped early. Only safety data were evaluated. |

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.
