Study Endpoints

Primary Endpoints

Percentage Change From Baseline in Low-density Lipoprotein Cholesterol (LDL-C)
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)

Blood samples taken at baseline (Week 4 for Period II; Week 12 for Period III) and after 8 weeks of treatment during each period to determine the LDL-C levels. The change from baseline after 8 weeks of treatment was recorded.

Global Flushing Severity Score (GFSS) during 7 days of treatment
during 7 days of treatment
Percentage Change From Baseline in the LDL-C/HDL-C Ratio
Baseline and Week 12

Blood samples taken at baseline and after 12 weeks of treatment to determine the LDL-C and HDL-C levels. The LDL-C/HDL-C ratio was then calculated for baseline and Week 12 and the change from baseline at Week 12 was recorded.

Secondary Endpoints

Percentage Change From Baseline in High-density Lipoprotein Cholesterol (HDL-C)
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)
Percentage of Participants With Consecutive Elevations in Alanine Aminotransferase (ALT) and/or Aspartate Aminotransferase (AST) of >=3 x Upper Limit of Normal (ULN)
up 20 weeks (12 weeks in Period I/II and 8 weeks in Period III)
Percentage of Participants With Creatine Kinase (CK) >=10 x ULN

Frequently asked questions about MK-0524A

What is MK-0524A used for?

MK-0524A is an investigational small molecule being developed for cardiovascular conditions, including primary hypercholesterolemia, mixed hyperlipidemia, dyslipidemia, and flushing. It has been studied in Phase 3 clinical trials for mixed hyperlipidemia and for flushing caused by niacin.

Who makes MK-0524A?

MK-0524A is being developed by Merck & Company, Inc., which trades on the New York Stock Exchange under the ticker MRK. The drug has completed Phase 3 clinical trials.

What phase is MK-0524A in?

MK-0524A has completed Phase 3 clinical trials. It is an investigational drug and remains in clinical development, with no approval status indicated. Two Phase 3 trials have been completed, along with earlier phase studies.

What clinical trials is MK-0524A in?

MK-0524A has been studied in two completed Phase 3 trials: NCT00289900, which enrolled 2,340 participants with mixed hyperlipidemia, and NCT00533611, which enrolled 330 participants to evaluate its effect on flushing caused by niacin. Both trials were randomized, double-blind, and placebo-controlled.

Is MK-0524A the same as MK-0524B?

MK-0524A is distinct from MK-0524B. While MK-0524A was studied in Phase 3 trials for mixed hyperlipidemia and flushing, MK-0524B appears in a Phase 1 bioequivalence study (NCT00943124) involving 220 healthy volunteers with dyslipidemia.
