Adverse Event
Časové okno: End of blinded phase (wk 9)
|
Occurrence of adverse events (AE) was compared between the placebo and vaccine groups during the blinded phase (the 1st 9 weeks).
At the end of this phase, all were unblinded, and those who received placebo crossed over to now receive vaccine.
All serious AEs and any other AEs that occurred 5 times or more are reported.
The exact binomial test was used to compare the occurrence of each AE between groups.

Immunogenicity of the DC/LNCaP Vaccine. Pre- vs Post-vaccination Bulk T Cell Proliferation (3H Thymidine Incorporation) by Type of Antigen. The "Number" Indicated is the Median Difference of Post-Pre, of Each Antigen Group.
Časové okno: pre- vs post-vaccination. Pre-vaccination T cells were collected at Wk 0 and post-vaccination T cells were collected at Wk 13
|
The difference between post minus pre-vaccination bulk T cell proliferation was calculated for each antigen.

Change in PSA Slope, Pre- vs Post-vaccination.
Časové okno: pre- vs post- vaccination PSA slopes.
|
To model the evolution of PSA (in log-scale) during the three study phases (pre-vaccine, vaccine, and post-vaccine phases), a mixed linear spline model was used.
Two knots (one at the start of the vaccine phase and the other at the start of the post-vaccine phase) were used to directly quantify the differences in slopes between each phase.
To account for the heterogeneous treatment effect and the repeated measures structure, random effects are incorporated into the model.
For the general model, random effects for the intercept, slope and the first knot were considered.
