Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in antigen presenting cell (APC) within bladder tumor tissue by immunohistochemical (IHC) assessment
Time Frame: Baseline up to 2 years
|
APC infiltration (CD68+, CD11c+, or CD83+) will be assessed by IHC staining, and quantitated by the number of APCs/um^2.
Therefore, the number of APCs will be normalized per unit area.
APC will be enumerated from 3 tissue regions: tumor/benign tissue interface (from here on referred to as the ?tumor interface?),
tumor center, and benign glands
|
Baseline up to 2 years
|
Change in circulating immune cells following intravesical talimogene laherparepvec, by flow cytometric assessment
Time Frame: Baseline up to 2 years
|
Flow cytometry will be performed in both pre- and post-treatment peripheral blood mononuclear cells to determine the change in T cell activation (both regulatory T cells and T effector cells) after intravesical talimogene laherparepvec therapy.
Descriptive statistics for continuous measurements will be used to summarize the changes.
|
Baseline up to 2 years
|
Change in T cell and other immune cell infiltration within bladder tumor tissue by IHC assessment
Time Frame: Baseline up to 2 years
|
T cell tumor infiltration (of selected T cell subsets) will be scored by IHC assessment, and scored by the number of T cells/um^2.
Therefore, the number of T cells will be normalized per unit area.
T cell-infiltration for both the pre- treatment diagnostic biopsy specimen and the post-treatment specimen will be quantitated in this fashion.
Separate scores will be reported for further characterization of T cell infiltration for tumor interface, tumor center, and benign tissue.
|
Baseline up to 2 years
|
Herpes simplex virus (HSV) status assessed by rate of HSV seroconversion in patients who were previously HSV-seronegative and relationship between HSV status and immunologic infiltration within tumor
Time Frame: Up to day 43
|
In patients who were previously HSV-seronegative, the proportion of patients with HSV seroconversion will be reported, with 95% confidence intervals.
The relationship between APC infiltration and baseline HSV status will be reported as a binary outcome: positive or negative.
Patients with baseline HSV negative status who experience seroconversion will be assessed by the chi-square test separately.
|
Up to day 43
|
Viral replication as measured by viral titers
Time Frame: Up to 2 years
|
Viral replication will be assessed by urinary viral titers drawn and assessed by polymerase chain reaction and cellular based assays as previously described.
These assays will be performed prior to each dose, as well as at +1 hour (h), +2 h, +24 h and +168 h, with a window of 6 hours for the +24 and +168 h to accommodate for logistical issues patients returning to the clinic.
Results will be summarized descriptively as change from baseline using appropriate statistical methods.

Antibody responses measured by spotted antigen arrays
Time Frame: Up to 6 weeks following therapy
|
To characterize antibody responses to a broad panel of antigens, sera will be collected at baseline and 6 weeks following therapy, and profiled using spotted antigen array.
After standard preprocess of the protein array data, Cluster and Treeview software will be used for unsupervised clustering of the data with Pearson correlation and complete linkage.
For each array, an antigen is identified as being detected if its value is above the median.
To determine the number of up- and down modulated antibodies, the difference in log2 intensity values of pretreatment and posttreatment samples will be

Apoptosis by IHC assessment of cleaved caspase-3
Time Frame: Up to 2 years
|
Will be scored on a 0-100 continuous scale based on % area that is positive for stain in regions of tumor.
Special attention will be paid to areas of high grade tumor for scoring purposes; areas of interface, benign, and tumor tissue will be scored separately.
For each subject, the change in cleaved caspase-3 IHC score following talimogene laherparepvec will be calculated in order to characterize the biological impact of talimogene laherparepvec in NMIBC.
Descriptive statistics for continuous measurements will be used to summary the IHC score change for each location.
Furthermore, univariate a

Change in PD-L1 expression by IHC assessment
Time Frame: Baseline up to 2 years
|
For each subject, the change in PD-L1 expression score defined as either an increase of decrease by at least 1 (on a scale of 1-3) following talimogene laherparepvec will be calculated for exploratory characterization of the impact on PD-L1 expression of talimogene laherparepvec in non-muscle invasive bladder cancer.
Descriptive statistics for categorical measurements will be used to summary the PD-L1 expression change for each location.
Furthermore, univariate analysis (proportion test) will be applied to explore the PD-L1 expression score change between locations.
