IMO, I think a deal  for both Zenith  and RVX has been in the works for over a year and was very close last November but negotiations may have been stalled,  maybe a year later with more clinical data from Zenith and where we are with the  betonmace trial 4 DSMB safety clearance and a good chance of a positive futility analysis that a deal of any sort could happen at anytime.  That being said the only thing we do know is a LOI for a regional license deal from the Aug 28 NR.  

My guess is CVR for both companies  which DM had mentioned years ago as very good option for both parties ,
