Has there been a clinical trial for Zytiga without the inclusion of Prednisone? If not, how do they conclude Zytiga 'must be taken' with prednisone?
My husband has not been on the prednisone while taking Zytiga and his labs (every 6 wks - 3 months) have been completely normal. Potassium remains in the high-normal range. Blood pressure remains in normal range. No fluid retention.
Just wondering.
