A view of the Regeneron Pharmaceuticals headquarters in Tarrytown, New York.
Shares of Regeneron fell nearly 9% Tuesday after the U.S. Food and Drug Administration declined to approve a higher-dose version of the company's blockbuster eye disease treatment.
Regeneron said the rejection was "solely due to an ongoing review of inspection findings at a third-party filler."
That suggests the drug could potentially win approval down the road.
But a delay won't help the company fight off threats to its Eylea drug franchise, which is facing competition from Roche Holdings ' eye drug, Vabysmo.
