CARLSBAD, Calif., Aug. 3, 2015 /PRNewswire/ -- Isis Pharmaceuticals Inc. (NASDAQ: ISIS), today announced that the FOCUS FH phase 3 study of KYNAMRO® (mipomersen sodium) in patients with severe heterozygous familial hypercholesterolemia (severe HeFH) met its primary efficacy endpoint, a statistically significant reduction in LDL-cholesterol after 60 weeks of treatment of once weekly injections of 200 mg of KYNAMRO compared to placebo. LDL-cholesterol reduction was similar to that observed in previous phase 3 studies. In addition, based on the data available for review, the safety profile of KYNAMRO observed in the FOCUS FH trial was similar to the safety profile reported in previous phase 3 studies. Genzyme will provide a more in depth review of the safety and efficacy data at a future medical meeting.
“We are pleased with the outcome of this fifth KYNAMRO randomized placebo controlled phase 3 trial, which shows statistically significant reductions in LDL-cholesterol in severe HeFH,” said Richard Geary, Ph.D., senior vice president of development at Isis Pharmaceuticals. “It is encouraging to see sustained LDL-C reductions over 60 weeks that were similar to what we’ve observed in previous phase 3 studies and a safety profile consistent with previous phase 3 and long-term extension studies. We look forward to the full analysis and presentation of this investigational data at an upcoming scientific meeting.”
“These investigational data provide additional information about KYNAMRO in the treatment of patients with severely elevated LDL-cholesterol and we look forward to further analysis of these data,” said Genzyme’s President and CEO, David Meeker, M.D.
ABOUT FOCUS FH
FOCUS FH was a multicenter, randomized, placebo-controlled, double-blind, parallel-group study that enrolled 310 patients aged 18 and older, followed by an open-label continuation. Cohort 1 included patients with severe HeFH with LDL-C 200 mg/dL plus coronary heart disease or LDL-C 300 mg/dL. Cohort 2 included patients with HeFH with LDL-C 160 mg/dL and <200 mg/dL plus coronary heart disease. Within each cohort, patients were randomized 2:1 to either 200 mg once weekly, 70 mg thrice weekly, or placebo for a 60 week study duration. Upon completion of the 60 week blinded treatment, patients had the option to enter the open label continuation period for 26 weeks and receive the full dose regimen of KYNAMRO according to the dosing schedule they were randomized to during the blinded treatment phase. The trial was conducted at 131 sites worldwide. The primary efficacy endpoint evaluated was the LDL-C percent change from baseline to week 61 for cohort 1 and each dose regimen.
ABOUT KYNAMRO® (mipomersen sodium) Injection 200 mg/mL
KYNAMRO is an oligonucleotide inhibitor of apolipoprotein B-100 synthesis indicated as an adjunct to lipid-lowering medications and diet to reduce low density lipoprotein-cholesterol (LDL-C), apolipoprotein B (apo B), total cholesterol (TC), and non-high density lipoprotein-cholesterol (non-HDL-C) in patients with homozygous familial hypercholesterolemia (HoFH). The safety and effectiveness of KYNAMRO have not been established in patients with hypercholesterolemia who do not have HoFH. The effect of KYNAMRO on cardiovascular morbidity and mortality has not been determined. The safety and effectiveness of KYNAMRO as an adjunct to LDL apheresis have not been established; therefore, the use of KYNAMRO as an adjunct to LDL apheresis is not recommended
About Homozygous Familial Hypercholesterolemia (HoFH)
HoFH is a rare genetic disease characterized by extreme cholesterol levels. People with HoFH have inherited mutations that limit the body’s ability to clear cholesterol. HoFH is extremely rare. As with other rare diseases, the true prevalence of HoFH may be underestimated because of inadequate data and under-diagnosis. Today, it is estimated that HoFH affects about 44,000 people globally. Medical literature includes different criteria for marking an HoFH diagnosis. HoFH may be diagnosed by clinical or genetic parameters, and may be considered in cases of unusually high LDL-C. Because HoFH is genetic, it is important that all family members of people with HoFH know their cholesterol levels, regardless of their age.
