PSA Response Rate
64 percentage of participants

SECONDARY outcome

Timeframe: At baseline, then weekly for 4 weeks up to 36 weeks

Population: The sponsor, Aventis Pasteur Limited, stopped the study early before it met the study accrual goal. Since the study ended early due to lack of funding. The pre-specified measurement values were not obtained and they will never be collected in the future.

Participants will be considered evaluable for a pain response if the baseline analgesic use was determined, and at least 4 weekly assessments of PPI and analgesic score are available from any 8-week period from the period after the initiation of therapy until discontinuation of study medication.

Outcome measures
