This is a "new to me" study, that actually started in July 2007 and is expected to end July 2010. It is phase-II and included 54 people, who are within 6 weeks of dx for type-1 (so honeymooners only). 2/3 of the people will get Atorvastatin (Lipitor) and will be compared against the 1/3 who don't get the drug.
The US clinical trial record is here: http://www.clinicaltrials.gov/ct2/show/NCT00529191
Now, for those of you who did a double take, when you saw that Lipitor was involved: Yes, this is the same statin drug which is used to lower cholesterol, and is the best selling drug in pharmaceutical history. There was no phase-I study for this treatment, because they knew the drug was safe, they went straight to phase-II.
Apparently, Atorvastatin (Lipitor) results in lower insulin requirements when give to "rodent models". I assume they are talking about NOD mice. I'm not sure why this drug might work, but it does lower inflamation, so maybe that's it.
I know of one study which gave Atorvastatin (Lipitor) to people with established type-1 diabetes in the hopes it would limit artery damage. It was not successful. However, I don't see that those guys reported A1C, BG, or insulin usage numbers turning the trial:
Of course, the studies are focused on different time frames, honeymoon vs. non-honeymoon so they may well come to different results.
