According to the profile, Sangamo was founded in 1995. That is over 16 years ago. Will there be any HIV patients left to treat by the time Sangamo comes out with an FDA approved drug? I'm a holder of this stock, and have been in and out of Sangamo for several years now. Originally purchased shares thinking the $$ coming out of the plant side of the business would yield some nice dough, with the human clinical stuff an added bonus. I'm truly disappointed with what's come out of this company so far.
