Could one of the more seasoned investors please ex

Could one of the more seasoned investors please explain to me how it all works when a company like CTIX sells off it's drugs to multiple companies?  I do not understand for instance if a company bought B well before K and P are ready to go, what happens to our shares / share prices?  It seems like a complex process, one of which I am a little worried about, mainly because I don't understand it.  Am I stating my question clearly, or does anyone understand what I'm asking?  Sorry, but I put it in the best south Texas English I could.  Shedding some light on this is greatly appreciated.  Thanks!
