They say it's because of the way it "fills up" the spaces on the cell membranes. I say that the 709 mg group got one less dose because of placebo run in and 14 weeks is just on the cusp of activity. I also just remembered that the 350 mg group needed a biopsy. Patients hate those. It makes it hard to recruit. They may have just gotten a more cohesive group because of the state of the disease necessary to agree to that.
