About
The primary purpose of this study was to evaluate the psychometric characteristics (reliability, validity, and responsiveness) of a Flushing ASsessment Tool (FAST) in subjects receiving niacin extended-release (NER) plus aspirin (ASA) daily for 6 weeks.
The FAST is a questionnaire that was developed to provide a detailed assessment of flushing symptoms and their impact in patients receiving niacin therapy. The effect of aspirin on flushing symptoms, as measured by the FAST, was also evaluated.
Full description
This study was designed to evaluate the psychometric characteristics of the FAST questionnaire.
The FAST is a self-administered questionnaire, completed using a hand-held electronic data capture device (LogPad e-diary). Subjects recorded the start and stop date and time of each flushing event, the presence and severity of individual flushing symptoms (redness, warmth, tingling and/or itching), and an overall assessment of their flushing experience.
Evaluation of the psychometric characteristics of the FAST was based on 3 primary data analyses: 1 ) test-retest reliability based on the intraclass correlation coefficient; 2) construct validity based on Spearman correlation coefficients; and 3) responsiveness based on changes in FAST scores. The mean and maximum severity of flushing events, as measured by the FAST, were the primary variables evaluated in each of the 3 data analyses mentioned above. Psychometric analyses were performed blinded to treatment group assignment.

- Have had severe peripheral artery disease as evidenced by intermittent claudication within three months of the Screening Visit.
- Have had uncontrolled cardiac arrhythmias within three months of the Screening Visit.
- Have symptomatic heart failure defined as dyspnea at rest or with exertion (mild peripheral edema is not exclusionary).

- Have a history of hepatitis (acute or chronic), obstructive liver disease, or alanine aminotransferase (ALT; serum glutamic pyruvic transaminase [SGPT]) or aspartate aminotransferase (AST; serum glutamic oxaloacetic transaminase [SGOT]) values >= 1.3 times the upper limit of normal (ULN) at the Screening Visit.
- Have creatine phosphokinase (CPK) >= 3 x ULN at the Screening Visit.
- Have used an investigational study drug or participated in an investigational study within 30 days of the Screening Visit.
- Have a health condition or laboratory abnormality (inclusive of clinically significant laboratory results at Screening Visit), which, in the opinion of the Investigator, may be adversely affected by the procedures or study medications in this study.
