I sure have no such examples. Like you I don't think the CDA count counts as much as the intent and interest behind any one agreement.
My only add is that IPIX is partnered - publicly at least - with Evonik and CoreRx, and I think both would fall in the specialty pharmaceutical company category, and I'm sure they both have CDA's with IPIX.
Of course those partners are not where the dough will show.
