The FDA’s prescribing data tells medical doctors they’ll contemplate stopping the drug after confirming through mind scans that sufferers have minimal plaque.
The FDA accepted Kisunla, identified chemically as donanemab, based mostly on outcomes from an 18-month research by which sufferers given getting the therapy declined about 22% extra slowly by way of reminiscence and cognitive capacity than those that acquired a dummy infusion.
The principle security problem was mind swelling and bleeding, an issue widespread to all plaque-targeting medication.
