(Reuters) -Blueprint Medicines Corp said on Friday the U.S. drug regulator had put on partial hold an early-stage trial of its experimental cancer drug due to safety concerns.
Some patients faced episodes of light sensitivity and blurred vision, the drug developer said.
Patients with advanced solid tumors currently enrolled in the trial will continue on the drug, the company said, while additional enrollments will be paused until the partial clinical hold is resolved.
Shares of the company were down 7.11% in premarket trading at $41.14
