The BROADEN Study: A Study of Volanesorsen (Formerly IONIS-APOCIIIRx) in Participants With Familial Partial Lipodystrophy
- Conditions
- Familial Partial Lipodystrophy
- Interventions
- Drug: Placebo
- Registration Number
- NCT02527343
- Lead Sponsor
- Akcea Therapeutics
- Brief Summary
The purpose of this study is to evaluate the efficacy and safety of volanesorsen given for 52 weeks in a randomized treatment (RT) period in participants with familial partial lipodystrophy (FPL). Following the randomized treatment period, participants who did not enter the open-label extension (OLE) period went straight to the 13-week post-treatment (PT) follow-up period and participants who were entered in the OLE period continued to receive volanesorsen for another 52 weeks (Weeks 53 to 104). Following the Week 104 visit of the OLE period, participants had an option of continued dosing for up to an additional 52 weeks (Week 105 to 156). Participants who did not enter the OLE period went straight to a 13-week post-treatment follow-up period. Following the Week 104 OLE period, participants were entered a 13-week post-treatment follow-up period, if they did not choose the option for continued dosing.

- Primary Outcome Measures
Name Time Method Randomized Treatment Period: Percent Change From Baseline to Month 3 in Fasting Triglycerides (TG) Baseline to Month 3 Baseline was defined as the average of Day 1 predose fasting assessment and the last fasting measurement prior to Day 1 predose fasting assessment. Month 3 value was defined as the average of Week 12 and Week 13 fasting TG assessments of the randomized treatment period. The data was analyzed using an analysis of covariance (ANCOVA) model with the randomization stratification factor (diagnosis of disease with or without genetics and family history) and treatment group as factors and log-transformed baseline fasting TG as a covariate.
- Secondary Outcome Measures
Name Time Method Randomized Treatment Period: Change From Baseline in Hemoglobin A1c (HbA1c) Baseline, Months 3, 6, 9, and 12 Baseline was defined as the last non-missing assessment prior to the first dose of study drug. Randomized treatment period: The Month 3 value was defined as Week 13, Month 6 value was defined as Week 26, Month 9 value was defined as Week 38 and Month 12 value was defined as Week 52.
Randomized Treatment Period: Percentage of Participants Who Achieved Greater Than or Equal to (≥) 40% Reduction in Fasting Triglyceride and ≥ 30% Reduction of Hepatic Fat Fraction at Month 6 Month 6 The baseline of TG is defined as the average of Day 1 pre-dose fasting assessment and the last fasting measurement prior to Day 1 pre-dose fasting assessment. The baseline of hepatic fat fraction is defined as the last non-missing assessment prior to the first dose of study drug. Randomized treatment period: Month 6 value was defined as average of Week 25 and Week 26 for fasting TG and Week 25 or Week 26 for hepatic fat fraction.
Randomized Treatment Period: Percent Change From Baseline in Hepatic Steatosis as Assessed by Hepatic Fat Fraction Using Magnetic Resonance Imaging (MRI) Baseline, Months 6 and 12 Baseline was defined as the last non-missing assessment prior to the first dose of study drug in the randomized treatment period. Randomized treatment period: Month 6 value was defined as Week 25 or Week 26 for MRI assessment and Month 12 was defined as Week 50 or Week 52 for MRI assessment. Hepatic steatosis is a reversible condition in which large vacuoles of triglyceride fat accumulate in the liver cells, causing nonspecific inflammation. Hepatic Steatosis was assessed by hepatic fat fraction using MRI.
Open Label Extension Period: Patient-Reported Pain From the first dose of study drug in open label extension period up to Week 117 Patient-reported pain was assessed by rating pain symptoms at its worst and least for the last 24 hours, on average, and at the moment, with 0 as the lowest score (no pain) and 10 as the highest score (worst pain as you can imagine). Patient-reported pain was also assessed by rating pain symptoms (rate pain on average, rate pain right now) that interfered with general activity, interfered with mood, walking ability, normal work, relations with other people, sleep, and enjoyment of life, with 0 as the lowest score (did not interfered) and 10 as the highest score (completely interfered). The scores from each assessment time point were averaged for all of the below reported categories.
Open Label Extension Period: Patient-Reported Hunger From the first dose of study drug in open label extension period up to Week 117 Patient-reported hunger was assessed by participants who completed a questionnaire about: how hungry you feel, how satisfied you feel, how full you feel, how much you think you can eat, like to eat something sweet, like to eat something salty, like to eat something savory and like to eat something fatty. Participants also rated the palatability of meals that included visual appeal, smell, taste, and aftertaste. Scores of 1-39 were categorized as mild, 40-69 as moderate, and 70-100 as severe. The scores from each assessment time point were averaged for all of the below reported categories.

Randomized Treatment Period: Change From Baseline in Mean Short Form-36 (SF-36) Weighted Sum of Scores Baseline, Weeks 13, 26 and 52 The SF-36 Health Survey is a 36-item, patient-reported survey of patient health. SF-36 consists of 8 health dimensions,which are weighted sums of the questions in each section. SF-36 included 36 questions related to 8 health dimensions:physical functioning, physical role functioning, bodily pain, general health perceptions, vitality, social role functioning,emotional role functioning, and mental health. Each dimension was scored on a scale of 0 to 100 where, higher score = better quality of life. A positive change from Baseline indicates improvement.

Randomized Treatment Period: Change From Baseline in Mean EQ-5D: Index Scores and Visual Analog Scale (VAS) Baseline, Weeks 13, 26 and 52 EQ-5D-5L is a standardized health-related quality of life questionnaire developed by EuroQol Group in order to provide a simple, generic measure of health for clinical and economic appraisal. EQ-5D-5L consists of two components: a health state profile and VAS. EQ-5D health state profile is comprised of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: 1=no problems, 2=slight problems, 3=moderate problems, 4=severe problems, and 5=extreme problems. The 5D-5L systems are converted into a single index utility score between 0 to 1, where higher score indicates a better health state. EQ-5D-5L- VAS is designed to rate the participant's current health state on a scale from 0 to 100, where 0 represents the worst imaginable health state and 100 represents the best imaginable health state. A negative change from baseline indicates worsening. A positive change from baseline indicates improvement.
