AstraZeneca and Ionis Pharmaceuticals saw their shares drop after their jointly developed heart disease drug, Wainua, failed a late-stage trial. The drug, designed as a monthly gene silencer injection, did not show a statistically significant benefit in reducing cardiovascular-related deaths. This setback caused AstraZeneca's stock to fall about 8% in London, reflecting investor disappointment. The failure raises questions about the future of this treatment and impacts both companies' market valuations.
