Even though this looks like a company with a solid drug coming down the pipe, like so many penny stocks it moves quite a bit based on news. The Price and Collins news has become a little old so I think interest isn't what it was, aside from the day traders, who you can see in the Level II screens on your brokerage account. They will sell for a couple pennies more and buy for a few cents less, over and over again.
My guess is we need a new news story to keep things rolling. Otherwise i would expect a lull.
And it doesn't appear that a whole lot of people know about this message board so unless there's news to talk about it probably will remain fairly quiet.
