I haven't thrown in the towel on Cotara up-front money yet, but the SPA that they were aiming for seems unlikely.
Some consider vague, tight-lipped, or unresponsive, as "playing things close to thier vest." To what end? A lower share price and more dilution?
Often times things are as they appear. They didn't give the HCV results because the HCV results were not good. There is no other logical reason. The current sp in a hot HCV maket should show you that. I wouldn't hold my breath awaiting this un-named medical conference in 2012 for the final results.
