Among the company's key revenue drivers, sales of Aranesp declined by 9 percent to $623 million, and sales of Epogen slid 2 percent to $653 million.
Combined sales of Neulasta and Neupogen rose 4 percent to $1.254 billion.

Amgen posted a net profit of $1.24 billion, or $1.28 per share, down from a profit of $1.39 billion, or $1.36 per share, a year ago. Wall Street analysts typically make their earnings estimates for adjusted, rather than net profit.
