The only thing I can think of as to why he might not have PRed the trial enrollment completion (despite doing so for US Rett and PDD, and presumably ALZ) is because it probably occurred in late November and would've been greeted by groans from those waiting for US-Rett results. Still, he should've mentioned it in the several times he's talked since then (thanks for nothing, crappy analysts covering AVXL), but has chosen not to. I say late November because that's when clintrials updated with the new estimated study completion date of February 28, which fits timeline-wise with having just finished enrollment.
FWIW, we got US Rett results 6 months after the enrollment complete PR (so late May with my hypothetical timeline), and 3 months, 1 week after the LPLV PR.
