First Oral PCSK9 Inhibitor to Lower LDL Cholesterol,

Rahway, New Jersey, USA--Merck (NYSE: MRK),announced the U.S. Food and Drug Administration (FDA) has approved LIPFENDRA® (enlicitide) tablets 20 mg as an adjunct to diet and exercise to reduce low-density lipoprotein cholesterol (LDL-C) in adults with hypercholesterolemia, the first FDA-approved oral PCSK9 inhibitor shown to lower LDL-C, also known as bad cholesterol, sets the world record for being the First Oral PCSK9 Inhibitor to Lower LDL Cholesterol, according to the WORLD RECORD ACADEMY.

First Oral PCSK9 Inhibitor to Lower LDL Cholesterol,

"The U.S. Food and Drug Administration approved Lipfendra (enlicitide), the first oral inhibitor of proprotein convertase subtilisin/kexin type 9 (PCSK9), as an adjunct to diet and exercise to reduce low-density lipoprotein cholesterol (LDL-C), or “bad” cholesterol, in adults with hypercholesterolemia, including those with heterozygous familial hypercholesterolemia (HeFH).


"PCSK9 inhibitors have previously been available only as injectable therapies. Lipfendra is administered as a once-daily oral tablet and provides an additional treatment option for adults who require further LDL-C reduction despite existing therapies. The approval also reflects continued advances in the development of therapies for chronic cardiovascular disease management.


"“Cardiovascular disease remains the leading cause of death in the United States, and elevated LDL cholesterol is one of its most important modifiable risk factors,” said Michael Davis, M.D., Ph.D., Acting Director of the FDA’s Center for Drug Evaluation and Research. “This approval provides an additional treatment option for adults with hypercholesterolemia and reflects the FDA’s broader commitment to supporting meaningful advances in patient access and tackling chronic diseases.”

"Hypercholesterolemia occurs when there is too much LDL-C in the blood. Over time, excess LDL-C can accumulate within the walls of arteries, contributing to the formation of plaques that narrow blood vessels and restrict blood flow. If a plaque ruptures, it can trigger the formation of a blood clot, increasi" "ng the risk of heart attack or stroke.


"Because high cholesterol typically causes no symptoms, many people are unaware they have the condition until it is detected through routine blood testing. Diet, physical inactivity, excess body weight, and inherited genetic conditions can all contribute to elevated cholesterol levels.


"Several classes of medications are available to lower LDL-C, including statins, ezetimibe, and injectable PCSK9 inhibitors. Lipfendra is the first oral therapy to inhibit PCSK9. (U.S. Food and Drug Administration)

"The efficacy and safety of Lipfendra were evaluated in two randomized, double-blind, placebo-controlled clinical trials involving 3,207 adults with hypercholesterolemia, including patients with and without HeFH, who were receiving maximally tolerated statin therapy. The primary endpoint in both studies was the percent change in LDL-C from baseline to Week 24 compared with placebo," the U.S. Food and Drug Administration says.


"In the first trial, which enrolled adults with established atherosclerotic cardiovascular disease (ASCVD) or those at high risk for ASCVD, participants had a mean baseline LDL-C of 96 mg/dL. Treatment with Lipfendra resulted in an average 56% reduction in LDL-C at Week 24 compared with placebo.


"In the second trial, which enrolled adults with HeFH, participants had a mean baseline LDL-C of 119 mg/dL. Treatment with Lipfendra resulted in an average 59% reduction in LDL-C at Week 24 compared with placebo.


"The application was also reviewed under the Commissioner’s National Priority Voucher (CNPV) pilot program, which is intended to help accelerate the review of therapies that address national public health priorities."
