Alexion Pharmaceuticals Inc. was mum Tuesday on the reason for a sharp rise in the stock price of the Cheshire drug maker.
Bloomberg News reported earlier that Alexion shares had risen in response to a Goldman Sachs analysis that the early success of Alexion's sole drug, Soliris, may make it a takeover target for another drug company.
An Alexion spokesman said the company would not comment on the reports.
Soliris has approval from the United States, Europe, Australia and other countries to treat a rare blood disorder.
Alexion shares closed up 98 cents, or 1.9 percent, at $53.83.
Based on Tuesday's closing price, Alexion's market capitalization is $4.8 billion.
