| Prostate Cancer Metastatic Prostate Cancer | Drug: ODM-201 Other: Placebo | Phase 2 |
The treatment of metastatic castration-resistant prostate cancer has evolved rapidly over the past few years. First line treatment with one of the novel antihormonal drugs abiraterone or enzalutamide followed by chemotherapy with docetaxel is now standard of care. If a patient has disease stabilization on chemotherapy he undergoes a watchful waiting period and further treatment is only started at the time of disease progression. This trial tests the immediate use of the novel androgen receptor antagonist ODM-201 as maintenance treatment after chemotherapy aiming at prolonging radiographic progression free survival as compared to watchful waiting.
The main objective of the trial is to assess impact of maintenance therapy with ODM-201 on radiographic progression-free survival (rPFS) of patients with mCRPC pretreated with novel hormonal agents who have non-progressive disease after chemotherapy with a taxane.

- Radiographic progression-free survival (rPFS) at 12 weeks [ Time Frame: At 12 weeks after treatment start ]Radiographic progression-free survival is defined as the time from treatment start to radiographic disease progression or death from any cause, whichever occurs earlier.
- Radiographic progression-free survival (rPFS) [ Time Frame: Every 12 weeks until disease progression (estimated up to 1 year) ]Radiographic progression-free survival is defined as the time from treatment start to radiographic disease progression or death from any cause, whichever occurs earlier.
- Time to PSA progression [ Time Frame: PSA level at baseline and every 4 weeks until disease progression (estimated up to 1 year) ]
PSA progression is defined as:
- In case PSA levels had not decreased under treatment with the study drug: ≥ 25% increase over baseline (last PSA measurement before treatment start) AND an increase in the absolute PSA value of ≥ 5 ng/mL.
- In case of PSA response < 50% under treatment with the study drug: ≥ 25% increase over the nadir AND an increase in the absolute PSA value of ≥ 5 ng/mL.
- In case of PSA response ≥ 50% under treatment with the study drug: ≥ 50% increase over the nadir AND an increase in the absolute PSA value of ≥ 5 ng/mL
- Time to symptomatic/clinical progression [ Time Frame: treatment start to the time point of symptomatic/clinical progression (estimated up to 1 year) ]
Symptomatic/clinical progression is defined by one of the following:
- Occurrence of a SRE due to bone metastases, defined as pathologic fracture, spinal cord compression, palliative radiation to bone, or surgery to bone
- Treating physician decides for intervention due to new disease related complications (e.g., urinary obstruction, hydronephrosis)
- Event-free survival [ Time Frame: treatment start until the event of interest (estimated up to 1 year) ]Event-free survival is defined as the time from treatment start until the event of interest.
- Overall survival [ Time Frame: time from trial randomization to the date of death from any cause (estimated up to 6 years) ]Overall survival is defined as the time from treatment start until death from any cause.
- PSA response (30%, 50%, 90% and best) [ Time Frame: PSA level at baseline and every 4 weeks until disease progression (estimated up to 1 year) ]
30% PSA response is defined as a decrease in PSA level of at least 30% (compared to baseline PSA).
50% PSA response is defined as a decrease in PSA level of at least 50% (compared to baseline PSA).
90% PSA response is defined as a decrease in PSA level of at least 90% (compared to baseline PSA).
Best PSA response is defined as the percentage of change in PSA from baseline to the maximum decline in PSA at any point under treatment. If there is a steady increase after baseline, the best response is defined as the percentage of change in PSA from baseline to the minimum increase in PSA at any point under treatment. Baseline is defined as the latest recorded measurement prior to the first dose of trial treatment.
