If you can secure some IP I'd go on a 50-50 jv with you, I have access to virtually unlimited amounts of Vitamin D :-). I am looking for a quick sale though while the market is ripe :-).
One more interesting note from the study is that the Vitamin D treated group had worse clinical characteristics to begin with: viral load (50% vs 42%, P < 0.01), and fibrosis score (> F2: 42% vs 19%, P < 0.001) than the controls.
So the observed benefit with Vitamin D could just represent regression to the mean?
