Research results suggest Johnson & Johnson's Zytiga could be bumped ahead of Pfizer's Xtandi on the list of drugs awaiting approval.
Whichever drug wins approval first could gain a major commercial advantage over the other. The drug approved second could generate as little as one-third the revenue of the first drug approved, MarketWatch notes.
Johnson & Johnson shares have traded up 6% in the last month, while Pfizer dropped over 4% in the same period.
Currently, J&J shares are slightly higher, while Pfizer's are slightly lower in mid-afternoon trading.
