My creeping phlox is splitting and turning brown in the center
Can I trim it back in the summer to try to rejuvenate it?

You can try giving it a pruning. It is as simple as taking an inch or so off the top, just like a haircut.
I would also try treating it with a fungicide and make sure that it is getting enough water too. In many areas, it has been a hot, dry summer and it may just be going dormant due to this but it also may be a fungus attacking the plant.
