It seems likely that there are, but I suspect that they would be quite difficult to detect.
Explanation:
There are thought to be about one trillion intergalactic 'rogue' stars in the Virgo cluster of 2500 galaxies. It seems likely that at least some of them have planets, but I would think they would be very difficult to detect.
