Lilly expects the U.S. Food and Drug Administration to decide by the end of this year whether to approve donanemab. The company had previously reported that 24% of the overall donanemab treatment group had brain swelling. The deaths of three trial patients were linked to the treatment, researchers reported. For high tau patients, donanemab was shown to slow disease progression by about 17%, while the benefit was 35% for those with low-to-intermediate tau levels. Both medications are also being studied in large trials to see if they have an impact on delaying onset of Alzheimer's disease symptoms.
