Hi Ann,
As far as I understand everything Greg wrote is OK. One of the differences between Vidaza and Dacogen seems to be that Vidaza is incorporated into both RNA and DNA. In contrast, Dacogen is incorporated solely into DNA.

Vidaza has showed better overall survival but we know that some patients that don’t respond to Vidaza do respond to Dacogen like the member Kirby Stone.
There are studies reporting that transfusion dependent low risk MDS patients don’t respond well to Vidaza.

One Dacogen study (rather small) showed clinical benefit was shown in 50% of those known to be intermediate-1 MDS.
