E.2.2 | Secondary objectives of the trial |
To compare the overall survival of subjects with relapsing and locally advanced prostate cancer responsive to androgen-deprivation therapy ADT treated with intermittent vs. continuous ADT To compare the effects of these treatment regimens on impotence, libido and vitality/fatigue as well as the physical and emotional well-being of these subjects To compare general symptoms, role functioning, global perception of quality of life and social functioning of subjects treated with these regimens To measure and compare bone turnover and exploratory biochemical/prognostic markers for disease progression in subjects treated with these regimens |

E.5 End points |
E.5.1 | Primary end point(s) |
Time to PSA progression Defined as three consecutive increasing PSA values and equal 4 ng/ml modified ASTRO definition 1 Based on the ASTRO definition the date of PSA progression is the mid-point between the PSA nadir during or after the induction period and the first of the three increasing PSA values and equal to 4 ng/ml. Time to progression is calculated from the date of randomization. The confirmatory PSA measurements second third should be performed at the next routine study visits. |
