Thanks Kiwi for pointing me here. I didn't recognize the symbol but then found out there was a name change from AcelRx, which I had looked at in the distant past. Will check this out here.
Notice right off the bat that there has been some net insider buying, not a whole lot, but still some. And, of course you mentioned Nantahala. Also I noticed they streamlined their board, reducing from 10 to 7 members. And, they mention keeping their M&A expertise with the company so they may be looking for some bigger group to swoop them up eventually.
