UK pharmaceutical company GlaxoSmithKline saw its biggest drop in shares for nearly three years after tests concluded that there was “no statistical difference” between one of its new and an existing lung drugs, reported the Daily Telegraph on 10 January.
The 12-week trial—showing that GSK’s new drug Relovair was no more effective than its existing drug Advair—caused the company’s shares to drop by 62p to £14.35.
