This is something you might want to find out from Tamara at IR. She was very willing to write Helpme_hanna about the numbers back in Jan., and CEO Geert was willing to talk numbers of remaining shares with that analyst on 3/30/15. Why don't you contact RXII and get the info? It's absolutely crucial for anyone considering to invest now or wait a few to several weeks..... Because if Tang is NOT finished, the s/p could easily be in the 0.40s or lower within a few weeks/months.
