Novartis' Entresto Patent Upheld: A Win for the Swiss Pharma Giant

Novartis AG, the Swiss pharmaceutical giant, has received a significant victory in its ongoing legal battle to protect its blockbuster heart failure drug, Entresto. The U.S. Court of Appeals for the Federal Circuit has reversed a lower court's decision, reinstating Novartis' patent for Entresto and blocking the immediate launch of generic competitors like MSN Pharmaceuticals' Entresto generic.

Entresto, a combination of sacubitril and valsartan, is Novartis' top-selling product, contributing over $5.6 billion in global sales during the first nine months of 2024. The drug is indicated for reducing the risk of cardiovascular death and hospitalization for heart failure in adult patients with chronic heart failure. With the patent reinstated, Novartis can maintain its market exclusivity for Entresto in the US until the patent expires in 2026.

The ruling by the Federal Circuit has significant implications for Novartis' Entresto sales and market share in the US. By preventing the immediate launch of generic competitors, Novartis can continue to sell Entresto at its current price, preserving its market share in the US heart failure drug market. This exclusivity period also gives Novartis more time to navigate potential pricing negotiations under the Inflation Reduction Act's drug price negotiation program.

The ruling is a win for Novartis, as it demonstrates the company's ability to protect its intellectual property and maintain its market position. This victory could boost investor confidence in Novartis, potentially leading to increased investment in the company's stock. However, Novartis may still face further legal challenges from generic competitors seeking to enter the market, and the outcome of these future litigations will also impact Entresto's sales and market share.
