Trial Outcomes & Findings for An Open-label Extension to Assess the Continued Efficacy of Omacor Plus Simvastatin (NCT NCT00678743)

NCT ID: NCT00678743

Last Updated: 2025-05-29

Results Overview

The primary efficacy endpoint will be the median percent change in non-HDL-C from baseline (average of weeks -2, -1, and 0) of the PRV-06009 (NCT00487591) double-blind study to Week 6 of PRV-06009X. Briefly, non-HDL-C was measured at Weeks -2, -1, and 0 from blood samples, and the concentrations of non-HDL-C in the blood at these timepoints were averaged to obtain baseline non-HDL-C concentration. Similarly, non-HDLC was measured at Week 6 from blood samples. Statistical analysis was performed comparing the change in non-HDL-C concentration from baseline to Week 6 and presented herein.

PRIMARY outcome

Timeframe: Week 6

Population: The results are from the 14 participants who were on Omacor 4 grams/day plus simvastatin 80 mg/day who completed Week 6.

The primary efficacy endpoint will be the median percent change in non-HDL-C from baseline (average of weeks -2, -1, and 0) of the PRV-06009 (NCT00487591) double-blind study to Week 6 of PRV-06009X. Briefly, non-HDL-C was measured at Weeks -2, -1, and 0 from blood samples, and the concentrations of non-HDL-C in the blood at these timepoints were averaged to obtain baseline non-HDL-C concentration. Similarly, non-HDLC was measured at Week 6 from blood samples. Statistical analysis was performed comparing the change in non-HDL-C concentration from baseline to Week 6 and presented herein.

n=16 participants at risk
Subjects who had successfully completed a 12-wk double-blind crossover study of P-OM3 plus simvastatin 20 mg/d were eligible for the open-label extension study. All subjects received Omacor 4 grams/day plus simvastatin 80 mg/day for the first 6 weeks followed by Omacor 4 grams/day plus simvastatin 80 mg/day or Omacor 4 grams/day plus simvastatin 40 mg/day. Assignment to 80 or 40 mg/day simvastatin after Week 6 was based on investigator's assessment of treatment needs. The adverse events results reported herein are from the 16 participants who started the extension study. 14 participants completed the first 6 weeks of the extension study and 13 participants completed the extension study in its entirety (up to Week 104). The adverse events were not analyzed by dose (i.e., 40 or 80 mg simvastatin) nor were they analyzed by the number of completers. Unfortunately, we no longer have access to our raw data due to a fire at our facility that destroyed our archived files.
