PRIMARY outcome

Timeframe: Assessed monthly from Baseline until the end of study (up to 8 months)

Population: The Intent-to-treat population, which included all patients enrolled in the study who took at least 1 dose of study medication.

PRIMARY outcome

Timeframe: From Baseline through to the end of study (up to 8 months)

Population: The Safety population included all enrolled patients who received at least 1 dose of study medication.

A treatment-related AE was defined as an event with a definite, probable, or possible causality to study medication. A serious AE is an event resulting in death, hospitalization, persistent or significant disability/incapacity, or is life threatening, a congenital anomaly/birth defect or requires medical or surgical intervention to prevent 1 of the outcomes above. The intensity of an AE was graded according to the National Cancer Institute common terminology criteria for adverse events (NCI-CTCAE) version 3.0: Grade 1 (Mild); Grade 2 (Moderate); Grade 3 (Severe); Grade 4 (life-threatening).

SECONDARY outcome

Timeframe: From Baseline until the end of study (up to 8 months).

Population: According to the protocol, the sponsor decided to close the study after it was determined that less than 2 of the first 22 patients showed a PSA50 response. Given that all patients discontinued the study due to lack of efficacy, the secondary endpoint of median time to progression was not assessed.

The time from first dosing day to the date of disease progression: * Progressive measurable disease by RECIST criteria (regardless of bone scan or prostate-specific antigen (PSA) results). * Development of unequivocal new lesions on bone scan without clinical suspicion of a "flare" reaction. * In patients who responded or had a decreased PSA from Baseline, a rise of 50% from PSA nadir, if the increase is ≥ 5 ng/mL or back to Baseline and confirmed by a 2nd value. * In patients with no decrease in PSA from Baseline, a 25% rise over Baseline and ≥ 5 ng/mL confirmed by a 2nd value.

SECONDARY outcome

Timeframe: From Baseline through the end of study (up to 8 months)

Population: According to the protocol, the sponsor decided to close the study after it was determined that less than 2 of the first 22 patients showed a PSA50 response. Given that all patients discontinued the study due to lack of efficacy, the secondary endpoint of tumor response rate was not assessed.

Complete Response (CR) and Partial Response (PR) defined by the Response Evaluation Criteria in Solid Tumor (RECIST) criteria. CR: Disappearance of all target and nontarget lesions. PR: At least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum longest diameter, or persistence of 1 or more nontarget lesion(s) or/and maintenance of tumor marker level above the normal limits.
