Official Title: An Open Label, 52-week, Safety and Tolerability Extension to a Randomized, Double-blind, Placebo Controlled Study of LCQ908 in Subjects With Familial Chylomicronemia Syndr

Brief Summary: This study was to determine long-term safety and tolerability, and continued efficacy in lowering triglycerides of LCQ908 in subjects with Familial Chylomicronemia Syndrome (FCS) (HLP type I).

Detailed Summary:

This study was an 52 weeks open label extension starting at the lowest treatment dose used in CLCQ908B2302/NCT01514461 (i.e., 10 mg) with optional up-titrations, to evaluate the overall long-term safety and tolerability of LCQ908 in patients with Familial Chylomicronemia Syndrome, who either discontinued from the CLCQ908B2302/NCT01514461 study (due to tolerability issues) or completed the CLCQ908B2302/NCT01514461 study after 52 weeks. In addition, patients who had previously completed study CLCQ908A2212/NCT01146522 were eligible to participate.

Following Protocol amendment 2, the original 52 week duration of this study (CLCQ908B2305) became Part A of LCQ908B2305 and a 78 week extension became Part B. However, following Protocol amendment 3, Part B was ended at the same time as the last patient of Part A completed 52 weeks. The reason for termination of Part B was the findings from the December 2014 interim analysis which suggested that the size of benefit that was anticipated from continued participation of patients in the 18 month extension trial (Part B) no longer supported trial extension beyond Part A.

Current Primary Outcome: Number of Patients With Any Adverse Events, Serious Adverse Events and Death [ Time Frame: 52 weeks ]

Original Primary Outcome: Number of patients wtih Adverse and Serious Adverse Events [ Time Frame: 52 weeks ]

AE/SAE monitoring will occur. Gastrointestinal AEs and any symptoms of phototoxicity; events suggestive or diagnostic of acute pancreatitis and will be adjudicated.


Current Secondary Outcome:

  • Changes From Baseline in Triglyceride Levels up to 52 Weeks [ Time Frame: Baseline, Week 12, 24 and 52 ]
    Blood samples were collected for a fasting lipid panel, including total triglycerides. Lipid measurements were collected after a 12 hour (overnight) fast. The maintenance of effect was assessed on triglyceride levels during continued therapy with LCQ908 for up to 52 weeks. For patients from LCQ908 arm of study CLCQ908A2212, baseline was the assessment obtained at Week 0 of current study. For patients from study CLCQ908B2302, baseline is defined as the average of values taken Day -3 and Week 0 (randomization) in study CLCQ908B2302. The geometric mean for the percentage (%) change is calculated from back-transforming the mean of the log transformed ratio to baseline values: (exp(mean of the log-transformed ratio to baseline values) -1)*100.
  • Changes From Baseline in Cholesterol Levels up to 52 Weeks [ Time Frame: Baseline, Week 12, 24 and 52 ]
    Blood samples were collected for a fasting lipid panel, including cholesterol level. Lipid measurements were collected after a 12 hour (overnight) fast. For patients from LCQ908 arm of study CLCQ908A2212, baseline was the assessment obtained at Week 0 of current study. For patients from study CLCQ908B2302, baseline is defined as the average of values taken Day -3 and Week 0 (randomization) in study CLCQ908B2302. The geometric mean for the percentage (%) change is calculated from back-transforming the mean of the log transformed ratio to baseline values: (exp(mean of the log-transformed ratio to baseline values) -1)*100.
  • Changes From Baseline in HDL and Non HDL Cholesterol Levels up to 52 Weeks [ Time Frame: Baseline, Week 12, 24 and 52 ]
    Blood samples were collected for a fasting lipid panel, including HDL and non HDL cholesterol level. Lipid measurements were collected after a 12 hour (overnight) fast. For patients from LCQ908 arm of study CLCQ908A2212, baseline was the assessment obtained at Week 0 of current study.

  • Changes From Baseline in Glycerol Levels up to 52 Weeks [ Time Frame: Baseline, Week 12, 24 and 52 ]
    Blood samples were collected for a fasting lipid panel, including glycerol level. Lipid measurements were collected after a 12 hour (overnight) fast.
