AstraZeneca Shares fell more than 5% on Tuesday morning, the biggest one-day drop in seven months, after the British pharmaceutical giant announced disappointing results from trials of lung cancer drugs.
The Covid-19 vaccine maker was trading at the bottom of the FTSE 100 and dragged the broader healthcare sector lower after data released on Monday showed its experimental drug did not significantly improve overall survival outcomes for patients.
Shares were down 4.9% as of 9:43 a.m. London time.
