2nd Biogen AD drug ...Biogen pulled the plug on the first drug.
Now they're working on this one ... safety again in question.
As enthusiasm mounts for a new experimental antibody that appears to slow cognitive decline in some Alzheimer’s patients, a third death linked to the drug during its clinical testing may amplify concerns about its safety. Science has obtained medical records showing a 79-year-old Florida woman participating in an ongoing trial of the antibody died in mid-September after experiencing extensive brain swelling and bleeding, as well as seizures. Multiple neuroscientists who reviewed the records at Science’s request believe her death was likely caused by the antibody, lecanemab.
