Novartis pilots patent cliff
Novartis continued to navigate the patent cliff in the first quarter of 2026 as sales of leading drugs such as Entresto for heart failure faced stiff competition from generics. Net sales for the company as a whole fell by 5% at constant exchange rates and by 1% at actual rates, while operating income contracted by an even larger amount as the company increased spending on research and development. The allocation for R&D in the quarter was $2.7 billion compared with $2.4 billion a year earlier.
