Amgen Stock Plummets Following Novartis Heart Drug Trial Setback
Amgen shares experienced their worst drop in more than two decades, dragging down the Dow after an experimental cardiovascular drug from Novartis failed a major study. The setback sent shockwaves through the medical and financial communities, raising doubts about the broader multibillion-dollar race for similar cholesterol and heart treatments.
