AstraZeneca PLCWainua failed to meet primary endpoint in Phase 3 trial for ATTR cardiomyopathy.

A late-stage clinical trial of Wainua, a neurological disorder treatment co-developed by AstraZeneca and Ionis Pharmaceuticals, failed to meet its primary goal of reducing cardiovascular death and recurrent heart events in patients with transthyretin amyloid cardiomyopathy. In the trial involving 1,432 patients, adding Wainua to standard care did not show a statistically significant benefit, and analysts criticized the trial design, noting that 57% of participants were already on stabilizer therapy. Following the results, AstraZeneca's share price briefly plunged nearly 10%, while Ionis shares fell close to 21%. In contrast, shares of rivals Alnylam Pharmaceuticals and BridgeBio Pharma rose between 6% and 16%.
