Pfizer is dropping the development of an experimental weight-loss pill due to side effects – a blow to the drug maker’s efforts to find new avenues for growth.

More than half of patients in a mid-stage study had to stop taking twice-daily danuglipron due to nausea and vomiting, according to a statement yesterday. The shares fell 3.9pc in trading before US markets opened.
