On Friday, Jan. 6, 2023, U.S. health officials approved Leqembi, a new Alzheimer’s drug that modestly slows the brain-robbing disease. The Food and Drug Administration granted the approval Friday for patients in the early stages of Alzheimer's.WASHINGTON — U.S.
“This drug is not a cure. It doesn’t stop people from getting worse, but it does measurably slow the progression of the disease,” said Dr. Joy Snider, a neurologist at Washington University in St. Louis. “That might mean someone could have an extra six months to a year of being able to drive.” Last week, a congressional report found that FDA's approval of a similar Alzheimer's drug called Aduhelm — also from Biogen and Eisai — was “rife with irregularities,” including a number of meetings with drug company staffers that went undocumented.
Some 6 million people in the U.S. and many more worldwide have Alzheimer’s, which gradually attacks areas of the brain needed for memory, reasoning, communication and daily tasks. The larger study tracked patients’ results on an 18-point scale that measures memory, judgment and other cognitive abilities. Doctors compile the rating from interviews with the patient and a close contact. After 18 months, patients receiving Leqembi declined more slowly — a difference of less than half a point on the scale — than patients who received a dummy infusion. The delay amounted to just over five months.
Schrag and some other researchers believe a meaningful improvement would require at least a difference of one full point on the 18-point scale.
