Trial Outcomes & Findings for Evaluation of a Flushing ASsessment Tool (FAST) in Subjects Receiving Niacin Extended-release Plus Aspirin (NCT NCT00630877)

NCT ID: NCT00630877

Last Updated: 2009-10-09

Results Overview

The change in maximum flushing severity scores from study start to Day 43 was compared in subjects classified as responders vs. nonresponders. Flushing severity was assessed using the FAST on a scale of 1 to 10, with 10 being the most severe. Changes in maximum flushing severity scores were negative if flushing symptoms improved and positive if flushing symptoms worsened.

Participant Flow

Subjects were enrolled at 41 sites in the United States between February and June, 2008.

Of the 276 subjects that were randomized, 5 discontinued from the study prior to receiving study drug due to withdrawal of consent (2), death in the family (1), positive pregnancy test (1), and lost to follow up (1).

PRIMARY outcome

Timeframe: Week 1 to Week 2

Population: Subjects with stable flushing symptoms from Week 1 to Week 2.

Test-retest reliability of the mean flushing severity score was evaluated. The intraclass correlation coefficient comparing flushing severity scores for Week 1 and Week 2 was examined to determine test-retest reliability. Flushing severity was assessed using the FAST on a scale of 1 to 10, with 10 being the most severe.

PRIMARY outcome

Timeframe: Week 1

Population: m-ITT population, defined as all randomized subjects who received at least 1 dose of study drug and who had at least 1 entry in the e-diary.

The relationship between mean flushing severity and overall flushing troublesomeness was evaluated by examining the Spearman rank-order correlation. Flushing severity was assessed using the FAST on a scale of 1 to 10, with 10 being the most severe. Overall flushing troublesomeness was assessed using the FAST on a scale of 1 to 10, with 10 being the most troublesome.

The relationship between the change in mean flushing severity scores from Week 1 to Week 2, and the subject-rated overall treatment effect scale administered at Week 2, was assessed by examining the Spearman rank-order correlation. Flushing severity was assessed using the FAST on a scale of 1 to 10, with 10 being the most severe. The overall treatment effect was assessed on a scale of 1 (symptoms are worse since study start), 2 (symptoms are about the same since study start), or 3 (symptoms are better since study start).

PRIMARY outcome

Timeframe: Study start to Day 43

Population: Subjects in the m-ITT population were classified as responders (improved flushing symptoms) or nonresponders (no change or worsened flushing symptoms) based on changes in flushing symptoms from study start to Day 43.

The change in mean flushing severity scores from study start to Day 43 was compared in subjects classified as responders vs. nonresponders. Flushing severity was assessed using the FAST on a scale of 1 to 10, with 10 being the most severe. Changes in mean flushing severity scores were negative if flushing symptoms improved and positive if flushing symptoms worsened.

SECONDARY outcome

Timeframe: Week 1 to Week 6

Population: m-ITT population, defined as all randomized subjects who received at least 1 dose of study drug and who had at least 1 entry in the e-diary.

The severity of flushing events was assessed as none, mild, moderate, severe, or very severe using the FAST. The maximum severity of flushing events overall during the study was compared among treatment groups.
