Hi Joseph,
There are several trials where they try Vidaza for consolidation after AML treatment but I have only found results from this study that is from 2010 (my doctor is the first author):

It is positive that your father has so good counts - Vidaza often decreases counts initially. It can take several cycles before Vidaza has a positive effect and doctors usually wait until the patients has received 6 cycles before they evaluate the result.
Kind regards
