SECONDARY outcome

Timeframe: Weeks 3-24 minus baseline, and Weeks 3-48 minus baseline

Population: Study participants who were in biochemically recurrent prostate cancer and not exposed to androgen deprivation therapy for the management of prostate cancer were evaluable for this endpoint.

"PSA slope log" was calculated using Memorial Sloan Kettering Cancer Center Prostate Cancer Nomograms (http://nomograms.mskcc.org/Prostate/PsaDoublingTime.aspx) Slope log represents the speed of change of a series of values. Thus, it is reported without any units as it is with a concept of ratio. The clinical meaning of PSA slope change would be decrease or increase of the "speed (velocity)" of changes in PSA, not the changes in PSA values. Decreasing PSA slope after the investigational treatment would mean the PSA rise is slower than pre-treatment baseline. Lowered PSA slope has been reported to show a relationship with was reported as related to improved outcomes.

SECONDARY outcome

Timeframe: Week 24 and Week 48 following immunization with the 2nd generation Multi-Epitope (ME) TARP

Population: 13/14 participants were evaluable for this outcome measure. Week 48 was not done due to issues in laboratory resources: samples were available in very limited number of participants and assay was not done (data not collected). As the samples were too low, the cost/resources needed to analyze week 48 were prohibitive funding wise considering the limited information to be generated with a small sample size.

Measure of activity to WT27-35 and EE29-37-9V TARP peptides was done by interferon (IFN)-gamma enzyme-linked immunosorbent spot (ELISPOT) assay. Positivity was defined by higher counts of spot counts than the counts in negative controls. and reactivity defined by higher spot counts than the negative controls.

OTHER_PRE_SPECIFIED outcome

Timeframe: Date treatment consent signed to date off study, approximately 82 months and 6 days

Here is the number of participants with serious and/or non-serious adverse events assessed by the Common Terminology Criteria for Adverse Events (CTCAE v.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.
