CAMBRIDGE, Mass., June 27, 2016 /PRNewswire/ -- Akcea Therapeutics, a wholly owned subsidiary of Ionis Pharmaceuticals, Inc. (NASDAQ: IONS) today announced the publication in Diabetes Care of positive clinical data from a Phase 2 study of volanesorsen in patients with high plasma triglyceride (TG) levels and type 2 diabetes. Results from the study showed that, in addition to reductions in plasma TG and apolipoprotein C-III (ApoC-III), a key factor in TG regulation, volanesorsen improved insulin sensitivity and glucose control. Volanesorsen is currently being evaluated in two pivotal Phase 3 studies—the APPROACH FCS study in patients with familial chylomicronemia syndrome (FCS) and the BROADEN FPL study in patients with familial partial lipodystrophy (FPL). In addition, the COMPASS study—a Phase 3 study designed to support global regulatory filings—is also ongoing.
The paper titled "Antisense-Mediated Lowering of Plasma Apolipoprotein C-III by Volanesorsen Improves Dyslipidemia and Insulin Sensitivity in Type 2 Diabetes" (Digenio et al., Diabetes Care June 2016) reported data from a Phase 2 double-blind, placebo-controlled study in fifteen patients randomized to weekly subcutaneous treatment with 300 mg of volanesorsen or placebo (2:1) for 13 weeks. In patients treated with volanesorsen, ApoC-III and TG levels decreased on average 88% and 69%, respectively, compared to baseline, and HDL-cholesterol increased an average of 42%. In addition, insulin sensitivity increased an average of 50% and correlated well with reductions in both plasma ApoC-III (r = -0.61, p=0.03) and TG (r = -0.68, p=0.01).
In addition, improvements in markers of glycemic control were observed, including statistically significant decreases in glycated albumin and fructosamine after three months of dosing, and a decrease of 0.44 percentage points in HbA1C observed three months post-dosing. The majority of adverse events reported in both groups in the study were mild in severity with no discontinuations from the study due to adverse events. There were no clinically relevant changes in blood serum chemistries, hematology, urinalysis, inflammatory markers, electrocardiogram, or vital signs.
"One of the most interesting findings in this study was that, in volanesorsen-treated patients with high triglycerides, substantial reductions in ApoC-III and triglycerides led to improved insulin sensitivity and glucose control. This is different from what is observed with currently approved triglyceride-lowering medications, which are not typically associated with this effect," said Dr. Louis O'Dea, Akcea's chief medical officer.
ABOUT VOLANESORSEN, FCS AND FPL
Volanesorsen is an antisense drug in development intended to treat patients with severely high triglycerides either as a single agent or in combination with other triglyceride-lowering agents. Volanesorsen is designed to reduce the production of ApoC-III, a protein produced in the liver that plays a central role in the regulation of plasma triglycerides.
Volanesorsen is currently being evaluated in two Phase 3 registrational studies (APPROACH FCS and BROADEN FPL) and a third Phase 3 study (COMPASS) designed to support global regulatory filings. APPROACH FCS is in patients with familial chylomicronemia syndrome (FCS). FCS is a rare, genetic disorder and may also be called familial chylomicronemia or Fredrickson Type 1 hyperlipoproteinemia, or familial lipoprotein lipase deficiency. People with FCS are unable to effectively clear lipid particles called chylomicrons. As a result, they have extremely high levels of triglycerides and are at risk of significant morbidity and mortality, including potentially life-threatening pancreatitis. Additional information on FCS is available at www.fcsfocus.com
A second Phase 3 study of volanesorsen (BROADEN) has begun in patients with familial partial lipodystrophy (FPL). FPL is a rare lipid disorder characterized by abnormal fat distribution across the body and a range of metabolic abnormalities, including severe insulin resistance, dyslipidemia and hypertriglyceridemia, hepatic steatosis and, in affected women, features of hyperandrogenism. People with FPL often present with polycystic ovarian syndrome or unusually insulin-resistant diabetes, and are at increased risk of acute pancreatitis in addition to long-term, progressive consequences including premature cardiovascular disease and liver disease, resulting in cirrhosis. They are unable to store fat or triglycerides in normal fat stores, so excess triglycerides are stored in the liver and muscle and accumulate at high levels in the bloodstream. Additional information on FPL is available through Lipodystrophy United at www.lipodystrophyunited.org.
