Amgen drug lowers cholesterol up to 66 percent in pivotal studies

By Bill Berkrot and Ransdell Pierson WASHINGTON (Reuters) – Amgen Inc’s drug from a high profile new class of experimental medicines lowered “bad” LDL cholesterol by 55 percent to 66 percent compared with a placebo in a trio of late-stage clinical trials, according to data presented on Saturday. Amgen had previously said the drug, evolocumab, met the main goals of five late-stage trials involving some 4,000 patients by significantly outperforming placebo or another cholesterol medicine in a variety of patient populations. “We’re seeing excellent efficacy and the safety profile appears no different than placebo, so you can’t get better than that,” Dr. Michael Koren, one of the lead investigators on two of the evolocumab studies, said in a telephone interview.
