AstraZeneca shares tumble after heart drug trial fails

Jul 9, 2026·read at Endpoints ↗Negative readoutNegative

AstraZeneca's stock fell in early trading on Thursday after the company disclosed that its experimental heart disease therapy, developed with Ionis Pharmaceuticals, did not meet primary endpoints in a late‑stage study.

The antisense drug, known as Wainua, was aimed at treating a specific cardiac condition, and the unexpected negative outcome represents a setback for the partnership.

The failure is likely to prompt both firms to reassess their cardiovascular pipelines, and investors reacted by pushing the share price lower.
