AstraZeneca and Ionis' Wainzua, a treatment for ATTR polyneuropathy, is set for EU approval after EMA's CHMP positive opinion. Wainzua, already approved in the US and Canada, reduces TTR levels by 82% and slows neurological impairment progression. It is also being developed for ATTR cardiomyopathy and is seen as a key drug for AZ's CVRM unit. Wainzua competes with Alnylam's Onpattro and Amvuttra, and Pfizer's Vyndamax/Vyndaqel.
