FDA Approves Leqvio as Standalone Cholesterol Treatment

Novartis (NVS.US) has announced that the U.S. Food and Drug Administration (FDA) has approved an expanded indication for its small interfering RNA (siRNA) therapy, Leqvio (inclisiran). This approval allows Leqvio to be used as a standalone treatment, in combination with diet and exercise, to lower low-density lipoprotein cholesterol (LDL-C) levels in adult patients with high cholesterol. The FDA's decision is based on the positive data demonstrating Leqvio's efficacy in reducing LDL-C levels through its targeting of PCSK9, a protein involved in the regulation of LDL receptors.

The updated drug label for Leqvio removes the previous requirement for the therapy to be used in combination with statin drugs or as an add-on to statin therapy. This change reflects the FDA's confidence in Leqvio's standalone efficacy and safety profile. The label update also includes a modification from "primary hyperlipidemia" to the more specific "high cholesterol," emphasizing Leqvio's role in lowering LDL-C levels. This development is significant as it broadens the therapeutic options for managing hypercholesterolemia, a condition that affects millions of people globally.

Leqvio, developed by Novartis, is the first siRNA therapy targeting PCSK9 mRNA. Initially approved in December 2021, Leqvio was indicated as an adjunct to diet and statin therapy for treating adults with primary hyperlipidemia, including heterozygous familial hypercholesterolemia (HeFH). The therapy works by inhibiting PCSK9, which increases the number of LDL receptors on liver cells, enhancing the clearance of LDL cholesterol from the bloodstream. This mechanism has been shown to be highly effective in lowering LDL-C levels, making Leqvio a valuable addition to the range of therapies available for managing hypercholesterolemia.

The FDA's proactive request to update the drug label underscores the growing acceptance and recognition of Leqvio as a standalone treatment option. This development is particularly important for patients who are intolerant to statins or for whom statin therapy is not effective. The removal of the statin co-administration requirement simplifies the treatment regimen and provides patients with a more flexible and potentially more effective treatment option. This is expected to improve patient adherence to treatment and ultimately lead to better health outcomes.

The approval of Leqvio as a standalone therapy is a significant milestone for Novartis, reinforcing the company's leadership in the field of RNA therapeutics. Novartis has been at the forefront of developing innovative therapies that target specific genetic pathways involved in disease processes. The success of Leqvio is a testament to the company's commitment to advancing the science of RNA therapeutics and bringing new treatment options to patients. The updated drug label for Leqvio is expected to have a positive impact on patient outcomes by providing a more flexible and effective treatment option for managing hypercholesterolemia. This development is likely to improve patient adherence to treatment and ultimately lead to better health outcomes.
