I didn't...all my powder was in RNN, VTUS, AEZS and CBLI...had I any funds I would have gone in heavy on ISR. I'm glad it took off for you. On my end, RNN had a very poor last 1.5 hours and AH was equally poor. I have a stop limit order in at 1.41 which will be most certainly taken out tomorrow AM if I don't cancel it. I'm faced with a decision to ride it out or get out tomorrow for a 180% profit. Not sure what I'll do yet but leaning towards trusting my DD and $2 price tag which was my planned exit point.
I don't chase stock...so I've missed ISR...it will run hot tomorrow on you and will probably go right by RNN. Hope you have a nice position. Good luck, friend.
