Pfizer says it will partner with German drug and chemical maker Merck in developing potential cancer drugs in a hot new medication class that harnesses the body's immune system to fight cancer.

Pfizer says the $850 million payment will cut profit this year, so it's lowered its 2014 earnings forecast range by a dime, to $1.40 to $1.49 per share.
