Study Description

Brief Summary:

Summary

In patients with prostate cancer (PC) who have only biochemically relapsed disease after curative treatment (or some locally advanced PC patients), hormonal therapy remains a de facto standard of care treatment. Adding docetaxel-based chemotherapy to a standard-of-care hormonal therapy has an increased potential to treat prostate cancer cell clones resistant to androgen withdrawal and to possibly shorten the duration of therapy needed to control the disease.

This clinical trial is designed on the basis of an unmet clinical need, as well as other factors including: 1) a consensus among investigators on endpoints for studies of patients with a rising PSA, 2) the ability to identify subjects at high risk for developing radiographic metastases, 3) the fact that hormonal therapy has already been shown to improve survival when applied early in the natural history, and 4) the availability of chemotherapy such as docetaxel that can improve survival in subjects with advanced disease.

It is our hypothesis that a more appropriate group of patients who may benefit from the curative potential of systemic chemo-hormonal modality is that with minimal, but detectable disease who have a high probability of developing metastatic disease, clinical symptoms and eventually death from prostate cancer in a defined time frame. The investigators hypothesize further that the approach is likely to be more effective at a time of minimal tumour burden, resulting in minimization of the overall burden of therapy and better quality of life while on treatment.

This trial will determine whether any benefit is gained by adding chemotherapy to hormonal therapy alone in the population of subjects with a rising PSA. Two therapeutic approaches will be compared in this two-arm randomized clinical trial. The control Arm A provides antiandrogen (bicalutamide 150 mg x 1) alone. The experimental Arm B involves treatment with docetaxel for 8-10 cycles and antiandrogen (bicalutamide 150 mg x 1) treatment. For the schematic representation of study design please see Section 7.3.1.

Subjects with a rising PSA following definitive local curative therapy will be eligible, if their PSA doubling time is < 12 months. Also PC patients planned for anti-.androgen therapy are eligible, with the same criteria. Subjects with radiographic metastases will be excluded. The primary endpoint of the trial is progression-free survival of subjects that do not experience biochemical failure at 60 months from the start of therapy.

Based on the yearly number of prostate cancer patients who undergo definitive local therapies and the estimated probabilities of relapse, upwards of 400 men (if +15% improvement) in the Scandinavian countries are potential candidates for this approach.

Outcome Measures

Primary Outcome Measures :

1. Progression free survival [ Time Frame: From date of randomization until the date of first documented progression or date of death from any cause, which ever came first, assessed up to 60 months ]

   Progression free survival defined as the time from randomization to the date of first documentation of:

   • PSA progression PSA progression is considered to occur when PSA is +2.0 ng/ml above nadir. A confirmatory PSA must be taken no less than 6 weeks following the first rising PSA above nadir +2.0 ng/ml. If that confirmatory PSA also exceeds the above parameters, then progression has occurred. If the confirmatory PSA fails to confirm progression, then the patient will remain on study.
   • Radiographic progression Outcome in patients who develop radiographically metastatic disease while on study will be defined as progression independent of their respective PSA values.

   These patients will be followed for evaluation of survival.

   - Death Death due to prostate cancer in the absence of previous documentation of disease progression,

Secondary Outcome Measures :

1. Difference between groups in PSA doubling time (PSADT). [ Time Frame: From date of randomization until the date of first documented PSADT, assessed up to 60 months ]
   The PSADT can be calculated by the natural log of 2 (0.693) divided by the slope of the relation between the log of PSA and the time of PSA measurement.
2. Difference between groups regarding QoL [ Time Frame: At date of randomization and yearly, assessed up to 60 months ]
   The quality of life (QoL) will be assessed using the FACT-P-T disease-specific subscale. The scoring will be in accordance with version 4 of the FACT manual.
3. Difference between groups regarding metastasis free survival [ Time Frame: From date of randomization until the date of first documented date of metastases, assessed yearly by bone-scan after first PSA_progression until first sign of metastasis, whichever came first, assessed up to 100 months ]
   Metastasis free survival will be assessed yearly by bone-scan after first PSA progression until the date of first documented metastasis on bone scan, date of death from any cause, whichever came first, assessed up to 100 months
4. Difference between groups regarding overall survival [ Time Frame: From date of randomization until the date of death from any cause reported yearly by the study sites up to 100 months ]
   Survival will be assessed yearly up to 100 months after inclusion
5. Difference between groups regarding cancer specific survival [ Time Frame: From date of randomization until date of death from prostate cancer,reported yearly by the study sites up to 100 months ]
   Cancer specific survival will be assessed yearly up to 100 months after inclusion
6. Measurement of grade of toxicity of given treatments [ Time Frame: At date of randomization, during treatment and follow up questionaries until 60 months ]
   Adverse events recording using NCI-CTCAE (v3.0)
