Have you tried to redesign, change ad size/type?
I have pages(one page that generates 2000+ pages actually) that has extremely low CTR. I've tried many designs with different ad sizes/types (by type I mean text/image), but noting worked. I guess there are just pages that hold the right combination of information, links and navigation, so visitors are not interested in ads they see there.
