Percent of Participants With Best Overall Response Rate in Safety Population and in Tumor Evaluable Population
The Best Overall Response Rate (BORR) was defined as the number of participants who had a confirmed complete response (CR) or partial response (PR) during the study divided by the total number of participants evaluated. Response was based on tumor assessment for both target and non-target lesions using: Clinical examination; Chest X-ray; Computed Tomography and Magnetic Resonance Imaging; Bone scan; Ultrasound. Per National Cancer Institute Response Evaluation Criteria in Solid Tumors (RECIST) v1.0, best overall response (BOR) for tumors was confirmed CR or PR. CR=disappearance of all target and non-target lesions; PR=at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the screening sum longest diameter. Confidence intervals (CIs) were computed using the Clopper and Pearson method.
Time frame: Day 1 up to 2 Years.
Percent of Participants With Prostate-Specific Antigen (PSA) Response After the First Dose by Day 85 In Participants With Hormone-Refractory Prostate Adenocarcinoma (HRPC)
The PSA response rate was defined as the number of participants who had at least a 50% decrease of the PSA value from the PSA reference value divided by the total number of participants evaluated (percent of participants). PSA reference value was the PSA concentration measured immediately prior to dosing on Day 1. PSA response was assessed using the Recommendations from the National Cancer Institute Prostate-Specific Antigen Working Group. A PSA response had to be confirmed at least 4 weeks after first response. 95% exact CIs were computed using the Clopper and Pearson method.
Time frame: Day 1 to Day 85
Number of Participants With Best Overall Response (BOR) by Category in Safety Population
Measurable and non-measurable disease/target lesions were evaluated according to National Cancer Institute standardized RECIST.Complete Response (CR)=disappearance of all target and non-target lesions and no new lesions; Partial Response=at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the screening sum longest diameter; Stable disease (SD)=neither sufficient shrinkage to qualify for partial response nor sufficient increase to qualify for progressive disease (PD), taking as reference the smallest sum longest diameter since treatment; PD=at least a 20% increase in the sum of the longest diameter recorded since screening, or the appearance of one or more new lesions. BOR was recorded between the first tumor assessment and last tumor assessment. CR and PR had to be confirmed by repeat assessment no less than 4 weeks after the criteria were first met. SD assessment must have met the criteria at least once at or after Week 12.
Time frame: Day 1 to Day 85
Percentage of Participants With Disease Control and Major Durable Disease Control
Disease control rate was defined as number of participants whose Best Overall Response (BOR) was complete response (CR), partial response (PR), or stable disease (SD) divided by the total number of participants. Major durable disease control rate was defined as the total number of participants whose BOR was CR, PR, or SD ≥24 weeks, divided by the total number of participants. Per RECIST v 1.0, BOR for tumors was confirmed CR or PR. CR=disappearance of all target and non-target lesions; PR=at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the screening sum longest diameter since treatment; SD=neither sufficient shrinkage to qualify for partial response nor sufficient increase to qualify for PD. PD=at least a 20% increase in the sum of the longest diameter recorded since screening, or the appearance of one or more new lesions. 95% CIs were computed using the Clopper and Pearson method.
Time frame: Day 1 to 2 Years
Median Time to Tumor Response and Duration of Tumor Response
Time to tumor response: from the date of first dose to the first date of tumor response (CR or PR confirmed at least 4 weeks later); for nonresponders, it was censored at the date of the maximum tumor assessment time in the dose cohort by the end of study. Duration of tumor response was calculated from the first date of response of CR or PR to the date of the first PD or the date of death if a participant died due to disease progression (whichever occurred first). Duration of response was censored at the last tumor assessment date by the end of study if a responder did not have PD or death. Nonresponders had the duration of response as an event of 0 days.
Time frame: Day 1 to 2 Years
Time to Tumor Progression and Tumor Progression Free Survival
Time to tumor progression (TTP) was measured in days from date of the first dose to the date of the first PD or the date of death if due to PD. For those who died without PD it was censored at the date of death. TTP was censored at the last tumor assessment by the end of study if a participant did not have PD or death. Tumor progression free survival (PFS) was measured in days from the date of first dose to the date of the first disease progression or to the date of death. PFS was censored at the last tumor assessment date by the end of study if a participant did not have PD or death.
Time frame: Day 1 to 2 Years
Median Time to PSA Progression in Days and Median PSA Progression Free Survival in Days in PSA Evaluable Population
Time to PSA progression: first dose to first PSA progression. Missing date of progression was censored: if death during the study, time to progression was right-censored at last PSA assessment; if no progression from first dose and still alive at end of study, time to progression was right-censored at last PSA assessment by end of study; if no PSA progression and one has discontinued from the study (other than death or PSA progression), time to progression was right-censored at last PSA assessment. PSA progression free survival (PFS): first dose to first PSA progression or death, whichever comes first. Missing date of progression was censored: if one did not have PSA progression from first dose and was still alive at end of study, PSA PFS was right-censored at last PSA assessment; if one does not have any progression and discontinued from the study for reasons other than death or progression, PFS was right-censored at last assessment. CI computed using Brookmeyer and Crowley method.
Time frame: Day 1 to 2 Years
Mean Change From Baseline in PSA Relative Velocity at Days 29, 57, and 85 With Cycle 1 in PSA Evaluable Population
PSA relative velocity (PSA RV) was defined as = (d\[PSA\]/dt)/ \[PSA\], where \[PSA\] =concentration of PSA, and t= time, and in the limit reflects the instantaneous change in PSA levels as a fraction of total PSA level. Decreases in PSA RV may occur while measured \[PSA\] is still rising, and may indicate that continued therapy may lead to a treatment benefit, particularly in the setting of immunotherapy, where expansion of an effective immune response is likely to require weeks to mature. Baseline PSA RV was based on the velocity of last PSA measurement before the first infusion of study drug and the screening PSA measurement.
Time frame: Day 29, Day 57, Day 85
Mean Change From Baseline in Electrocardiogram Parameters PR, QRS and QT in Safety Population
12-lead ECGs were performed at screening, baseline, Day 2 and at completion of the dose cycle (Day 85 in first dose cycle). In those participants undergoing re-treatment, ECG was repeated at the completion of the re-treatment. Baseline was defined as the last measurement before the first dose of study drug, which was calculated from pre-dose or from screening if pre-dose was not available. PR, QRS and QT interval were measured in milliseconds (msec).
