I suspect that the 2015 "last modified date" and the fact that it's listed as completed (from which you're deducing a 2015 completion date) on the U Copenhagen/Aarhus University Hospital NR study is just some kind of internal disconnect. It appears that it has just recently been completed, and is probably being written up now:

... We aim to determine if NR treatment can improve insulin sensitivity, substrate metabolism and body composition in obese, non‐diabetic humans.
Material and methods: In a randomized, double‐blinded, placebo controlled trial, 40 obese, healthy, middle‐aged men receive NR treatment 1 g twice daily or placebo for 12 weeks. We determine the effects of NR treatment on insulin sensitivity by a hyperinsulinemic euglycemic clamp and substrate metabolism by indirect calorimetry and labeled substrates. Alterations in body composition and fat mass distribution are determined by DEXA and MRI scans and measurements of intra‐hepatic and intramyocellular lipid contents are obtained by MR spectroscopy.
Furthermore analysis of mitochondrial function in permeabilized muscle fibers by mitochondrial respirometry, intestinal bacteria composition by 16S rRNA sequencing and incretin hormone response during an oral glucose tolerance test will be performed.
Results: Baseline characteristics (n=40) are presented as mean (±SD). BMI 32.9 (±2.7) kg/m2, fat percentage 30.7 % (±4,1), age 58.7 (±7.9) ‐ range 40‐70. Insulin clamps at baseline have a mean M‐value of 2.4 (±1.1) mg/kg/min suggesting that the study group is insulin resistant as a whole. Completion of the trial is expected in April 2017 and preliminary data, including the primary endpoint insulin sensitivity, will be ready for presentation shortly hereafter.
Conclusions: This is the first human clinical trial investigating the long‐term effects of NR supplementation on whole‐body insulin sensitivity, body composition and glucose homeostasis, and the potential role of NR as an anti‐diabetic agent.
He says "by April," but the conference was in May: I expect that this is just because you have to have your abstract submitted well in advance of conferences in order to give them time to get the abstract book formatted and printed up. He may even have presented his data at the conference.
In any case, if he completed analysis in April or May, it will still be some months before they're published in a scientific journal.
Similarly, I wouldn't read too much into the delay in the publication of the Chromadex and Elysium studies. Journal publication can take forever, and it's possible that they've been asked to conduct additional analyses or experimental studies (not whole new trials) to justify some claims they've made. And it is routine for journals (and higher-tier journals in particular) to insist on an embargo to the press until publication (though I'm surprised by the discipline showed by the FASEB Summit attendees on this point: in the age of social media, scientific conference results are often leaked, and clearly this one has significant scientific and public interest no matter which way the results went — and this was an NAD+ specialist conference).
Blue, are you sure Guarente said there were 6 more Basis trials in the works? I seem to recall him indicating there were 6 more trials in the works, but that they were for novel products to expand Elysium's line, consistent with their originally-stated plans.
