Mast Therapeutics, Inc. (MSTX)

Can anyone give synopsis of :1.) why alpha's thinks this stock is worth tracking? Having trouble retrieving report and read they see huge upside and huge downside potential. 2.) Is management purposefully selling at forties? Why not just sell in .5 area? Trying to figure this stock out. 3.) Also, is the method used to remove the toxins from the polymers a proprietary function/ invention that another company cannot reproduce? 4.) Is the method patented yet, or still patent pending? Thankyou for the explanations if you can address any of these.
