Rolf Kelley has run this rapid in its entirety, but I have no idea if anybody else has repeated that feat.  The rapid is extremely long and dangerous.  Several people have been running in to run the last waterfall, which itself is a solid class V+ move.  It has a difficult entrance ledge that feeds directly into the ~18 foot waterfall with a rock in the landing zone requiring a mandatory solid boof.  For most people the entire rapid is a portage.
