Eli Lilly’s Alzheimer’s drug receives unanimous FDA panel support

An independent panel advising the FDA unanimously agreed that Eli Lilly's Alzheimer's treatment, donanemab, offers more benefits than risks. The decision paves the way for the FDA's final verdict, anticipated after a meeting prompted by divergent trial designs. Donanemab targets toxic plaques and showed promising effectiveness, with innovative trial features earning praise. While challenges remain, analysts foresee potential FDA approval, marking a significant advance in Alzheimer's therapeutics..Sign up for your early morning brew of the BizNews Insider to keep you up to speed with the content that matters.

They suggested that doctors prescribing the drug need to be educated on the heightened risk and discuss that with patients..In Lilly's large clinical trial, donanemab, given by infusion once a month, slowed progression of memory and thinking problems by 29% overall, roughly comparable to the 27% slowing seen with Leqembi..Brain swelling and bleeding – a known risk for this class of drugs – occurred in 24% and 31%, respectively for those taking donanemab and three patients died..In Eisai and Biogen's late-stage study, 12.6% of participants taking Leqembi experienced brain swelling and 17.3% brain bleeding..Leqembi was approved with the agency's strongest "boxed" warning about the risk of potentially dangerous brain swelling and bleeding that applies to all drugs in the class..Several panel members commended Lilly's innovative trial design, which allowed participants to stop treatment as soon as brain imaging showed the amyloid plaque was cleared, but they said it could make the treatment harder for doctors to know when to withdraw treatment, and when to restart it if needed..Lilly said it is planning trials to test the treatment in patients genetically predisposed to develop Alzheimer's, including people with Down syndrome..Jefferies analyst Michael Yee said in a note to clients that the vote "sets up an eventual FDA approval," adding that having two players on the market would be a good thing longer-term..Shares of the Indianapolis drugmaker closed up 1.8% at $865. .Read also:.🔒 Revolutionary blood test for Alzheimer's raises ethical questions, hope for early interventionNew study reveals altered gut bacteria as potential biomarker for preclinical Alzheimer's diseaseBreakthrough in Alzheimer's research: examining the pros and cons of two promising new drugs.SOURCE: REUTERS
