“I think they made the right decision. It makes the drug available to patients while requiring the company to do more research to prove its benefit,” mentioned Dr. Howard Fillit, chief science officer of the Alzheimer’s Drug Discovery (NASDAQ:) Foundation.
Some trial patients skilled doubtlessly harmful mind swelling. The FDA suggested that patients who expertise the aspect impact ought to be monitored however not essentially taken off the drug.
