Anticholesterol drug cuts death risk
Miami (AFP) - The anti-cholesterol drug Praluent (alirocumab), made by France's Sanofi Pharmaceuticals, is linked to a 15 percent lower risk of major cardiovascular events like heart attack and stroke, a study said Saturday.
Alirocumab was also associated with a 15 percent reduction in death from any cause, marking the first evidence that this relatively new class of drugs, called PCSK9 inhibitors, can extend lives.
The benefit was even greater among those with stubbornly high "bad," or LDL cholesterol, above 100 mg/dL. That group saw a 29 percent reduction in death from any cause after taking the drug for two years.
PCSK9 inhibitors are monoclonal antibodies which target and inactivate a specific protein in the liver, dramatically reducing the amount of harmful LDL cholesterol circulating in the bloodstream.
Research has shown these drugs, delivered by injection every two to four weeks, may work even better than statins, which are the traditional first line of treatment for high cholesterol.
High cholesterol is a key factor in coronary artery disease, the most common kind of heart disease and the number one killer of men and women worldwide, according to the World Health Organization.
But neither Praluent or its main competitor, Repatha (evolocumab) made by Amgen Pharmaceuticals, has achieved major commercial success due to their hefty annual price tag of more than $14,000 (11,300 euros) per patient.
Last year, researchers reported similar results for Repatha, which also cut the risk of heart attack, stroke, and hospitalization for blocked arteries by 15 percent.
"Now that we have two trials that consistently show benefits from PCSK9 inhibitors, and given the mortality benefit that we are reporting here for the first time, I think these results may change the equation for these drugs," said Philippe Gabriel Steg, chief of cardiology at Hopital Bichat in Paris and co-chair of the study.
"We're not just talking about preventing nonfatal events such as heart attacks but actually preserving life."

The findings described Saturday at the American College of Cardiology conference in Orlando, Florida, were based on an international trial of nearly 19,000 people in 57 countries, randomly assigned to either alirocumab or a placebo.Read More...
