For the primary endpoint of the study, volanesorsen-treated patients (n=75) achieved a statistically significant (p<0.0001) mean reduction in triglycerides of 71.2% from baseline after 13 weeks of treatment, compared with a mean reduction of 0.9% in placebo-treated patients (n=38).  This represented a mean absolute reduction of 869 mg/dl in treated patients.  The treatment effect observed was sustained through the end of the 26 week treatment period.

In a subset of seven patients with familial chylomicronemia syndrome (FCS), whose average incoming triglyceride level was 2,280 mg/dl, volanesorsen-treated patients (n=5) achieved a mean reduction in triglycerides of 73% from baseline after 13 weeks of treatment, compared with a mean increase of 70% in placebo-treated patients (n=2).  This represented a mean absolute reduction of 1,511 mg/dl in treated patients.  The treatment effect observed was sustained through the end of the 26-week treatment period.

In addition, 82% of patients treated with volanesorsen, including three of the FCS patients, achieved triglyceride levels less than 500 mg/dl after 13 weeks of treatment, compared to 14% of placebo-treated patients (p<0.0001).
