BillyH. My aggressive treatment is part of a clinical trial at UCLA medical school and hospital. I had 6 months of ADT ( lupron ) and Erleada, then 1 month break when I had RP, then 6 more months of Lupron and Erleada. Now they monitor my PSA every 3 Months and they are taking a pet scan in the first 3 month monitor period. 13 months after the ADT, Erleada and RP my PSA was .01 and testaterom (sp) was also very low. If my PSA or pet scan results create a concern, I suspect that they will put me back on ADT and Erleada, which I tolerated satisfactorily.
