Shares of U.S. drugmaker Merck are up about 2.5% in premarket trading after reporting that its blockbuster cancer drug Keytruda fueled a higher-than-expected increase in quarterly sales and earnings.
Merck also raised and narrowed its forecast range for full-year sales and earnings.
Sales of Keytruda, the worlds top-selling drug, rose 20% to $6.9 billion for the first quarter. Merck has become dependent on Keytruda for more than 40% of company sales, and faces a revenue hit when Keytrudas main U.S. patent expires in 2028, which will allow low-cost copycat competition.
But analysts are growing increasingly confident that Merck will be able to offset the Keytruda patent hit with sales from newer products, including cardiovascular drug Winrevair, and a pneumococcal vaccine for adults that may get regulatory clearance in June.
