Background

Evolocumab is a monoclonal antibody designed for the treatment of hyperlipidemia by Amgen. It is a subcutaneous injection approved by the FDA for individuals on maximum statin therapy who still require additional LDL-cholesterol lowering. It is approved for both homozygous and heterozygous familial cholesterolemia as an adjunct to other first-line therapies. Evolocumab is a human IgG2 monoclonal antibody that targets the proprotein convertase subtilisin/kexin type 9 (PCSK9). PCSK9 is a protein that targets LDL receptors for degradation, therefore reducing the liver's ability to remove LDL-cholesterol (LDL-C), or "bad" cholesterol, from the blood. Evolocumab is designed to bind to PCSK9 and inhibit PCSK9 from binding to LDL receptors on the liver surface, resulting in more LDL receptors on the surface of the liver to remove LDL-C from the blood. Evolocumab is the second PCSK9 inhibitor on the market, first being alirocumab.

Indication

Evolocumab is indicated in adult patients with established cardiovascular disease to reduce the risk of myocardial infarction, stroke, and coronary revascularization. It is also indicated as an adjunct to diet, alone or in combination with other hypolipidemic treatments, in adults with primary hyperlipidemia (and in pediatric patients ≥10 years old with heterozygous familial hypercholesterolemia) to reduce LDL-C. In addition, it is indicated adjunctly to other hypolipidemic treatments in patients ≥10 years old with homozygous familiar hypercholesterolemia to reduce LDL-C.

Associated Conditions
Coronary Revascularization, Myocardial Infarction, Stroke, Increases in serum total low-density lipoprotein (LDL)

Regeneron Wins $407 Million in Landmark Antitrust Case Against Amgen Over PCSK9 Drug Market

• A federal jury awarded Regeneron $407 million in damages after finding Amgen violated antitrust laws by using cross-therapeutic bundled rebates to block Praluent from competing with Repatha in the PCSK9 inhibitor market. • The verdict includes $135.6 million in compensatory damages and $271.2 million in punitive damages, signaling a strong deterrent against anticompetitive bundling practices in pharmaceutical markets. • Amgen was found to have leveraged its blockbuster drugs Enbrel and Otezla to force pharmacy benefit managers to exclude Praluent, creating an uneven playing field not based on clinical merit or price.

UPC Issues Landmark Ruling on Second Medical Use Patents in Cholesterol Drug Dispute

• The Unified Patent Court's Düsseldorf Local Division has issued its first-ever ruling on second medical use patent infringement in a dispute between Sanofi/Regeneron and Amgen over PCSK9 inhibitor drugs. • The court established a two-part test for infringement: the product must be marketed in a way that leads to the patented use, and the alleged infringer must know or should have known about such use. • While upholding the validity of Sanofi/Regeneron's patent for using PCSK9 inhibitors to reduce lipoprotein(a) levels, the court ruled Amgen's Repatha did not infringe as there was insufficient evidence of it being prescribed for this purpose.

UPC Sets Precedent in First Second Medical Use Patent Ruling: Sanofi and Regeneron Lose Against Amgen

• The Unified Patent Court (UPC) issued its first ruling on second medical use pharmaceutical patent claims, upholding Sanofi and Regeneron's patent as valid but finding no infringement by Amgen's cholesterol drug Repatha. • The landmark decision establishes that proving infringement requires evidence of actual or likely off-label use of a drug for the patented indication, plus the alleged infringer's awareness of such use. • The Düsseldorf Local Division adopted a "foreseeability" test for infringement, determining that rights holders must demonstrate the generic manufacturer "knows or reasonably should have known" about off-label prescriptions.
