Amgen Q3 profit beats but FDA concern hits shares

NEW YORK (Reuters) – Amgen Inc (AMGN.O) reported a better-than-expected profit as cost cuts and lower taxes helped offset a steep decline in sales of its Aranesp anemia drug, but regulatory concerns about its closely-watched osteoporosis drug sent shares lower.

The company said on Wednesday U.S. health regulators have requested additional clinical trial data on its experimental osteoporosis drug denosumab for prevention of bone loss in prostate and breast cancer patients.
