Pfizer Inc. (NYSE:PFE) opted out of bidding for Onyx Pharmaceuticals Inc. (NASDAQ:ONXX) this week, placing Amgen Inc. (NASDAQ:AMGN) in the lead to buy the cancer-drug maker, Reuters reported on Friday.
Shares in Onyx, valued at about $9.24 billion on Friday, fell nearly 2 percent on Friday after plummeting more than 3.3 percent on Thursday, when Reuters cited two unnamed sources saying Pfizer was no longer a suitor for the San Francisco company.
Onyx announced its sale process on June 30 after it rejected Amgen’s $120-per-share bid.

Two days before the sale was announced, shares in the California company closed at $86.82. The price has since surged more than 50 percent.
