- The relative Epidermal Growth Factor Receptor (EGFR) expression level [ Time Frame: Up to 28 days ]Will be analyzed as a continuous variable. A two-sample Wilcoxon rank-sum test will be conducted to test whether there is significant differences of the log-transformed EGFR expression level measured by reverse transcriptase polymerase chain reaction (rt-PCR) in normal appearing urothelium adjacent to tumor (measured as a ratio relative to urothelium and lamina-propria specific markers) in participants treated with anti-androgen therapy versus (vs.) untreated participants.
- Effect of apalutamide on EGFR expression [ Time Frame: Up to 28 days ]A two-sample Wilcoxon rank-sum test will be conducted to compare the difference of EGFR expression in androgen receptor (AR) positive participants treated with and without apalutamide
- AR expression in adjacent urothelium with EGFR expression in treated and untreated participants. [ Time Frame: Up to 28 days ]Pearson correlation and Spearman's rank correlation will be calculated between the AR expression and EGFR expression.

- Morbidities of treatment [ Time Frame: Up to 28 days ]Breast tenderness, sexual or urinary side effects, seizure(s), depression, abnormal liver function tests (LFTs). Will be summarized by descriptive statistics such as rates and proportions and compared between untreated and apalutamide using nonparametric tests such as the Kurskal-Wallis test.
- Pre vs. post intervention urinary biomarkers [ Time Frame: Up to 28 days ]Comparison of pre vs. post intervention urinary biomarkers (CxBladderTM) in both groups, examining the 5 ribonucleic acids (RNAs) (by rtPCR) that make up the test, both as a group and each RNA separately.
- Analysis of fibroblast growth factor receptor 3 (FGFR3) in deoxyribonucleic acid (DNA) [ Time Frame: Up to 28 days ]Extracted from fixed paraffin embedded (FFPE) blocks from neighboring normal urothelium and tumor tissue in treated vs. untreated participants. Will be summarized by descriptive statistics such as rates and proportions and compared between untreated and apalutamide using nonparametric tests such as the Kurskal-Wallis test.
- Changes in the tumor immune microenvironment pre- and post-apalutamide [ Time Frame: Up to 28 days ]Will be summarized by descriptive statistics such as rates and proportions and compared between untreated and apalutamide using nonparametric tests such as the Kurskal-Wallis test.
- Analysis of tumor (biopsy specimen) infiltrating CD8+ T-cells [ Time Frame: Up to 28 days ]Measured by single RNA Sequencing (scRNA-seq) and high dimensional spectral flow cytometry to evaluate TCF1/Tcf7 transcript levels, and perform IHC of CD44+, CD62L, and SLAMF6. Will be summarized by descriptive statistics such as rates and proportions and compared between untreated and apalutamide using nonparametric tests such as the Kurskal-Wallis test.
- Exploratory markers [ Time Frame: Up to 28 days ]Will be summarized by descriptive statistics such as rates and proportions and compared between untreated and apalutamide using nonparametric tests such as the Kurskal-Wallis test.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | Male |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
-
Biologic male adults ( >= 18 years old)
- Note: Because no dosing or adverse event (AE) data are currently available on the use of apalutamide in participants < 18 years of age, children are excluded from this study but will be eligible for future pediatric trials, if applicable.
- Have suspected non-muscle invasive bladder carcinoma (NMIBC) on clinic-based cystoscopy or imaging as viewed by an American Urological Association (AUA) board-certified urologist
-
Have had cross sectional imaging of the abdomen and pelvis (computed tomography [CT] or magnetic resonance imaging [MRI] with or without contrast) within 6 months prior to enrollment with no signs of upper tract urothelial cancer (UC), invasive, nor metastatic disease
- Note: If adenopathy or upper tract abnormalities are identified, a negative biopsy and or ureteroscopy is required prior to enrollment
