There were two press releases Jan 27 both about Dr Sacha accepted presentations: one at CROI and the other Keystone Symposium. We will see if they respond about why it was removed from the website. They may not answer, if I hazarded a guess, I would say maybe the pr contained some info that is embargoed until after the presentation.
