Who can join

Age: 18 and older. Sex: male. Healthy volunteers: not accepted.

You may qualify if…

• Subjects with histologically confirmed NMIBC who have undergone their TURBT.
• Per the European Association of Urology (EAU) guidelines, only subjects with "Intermediate" or "High risk" bladder cancer will be enrolled21:
• For patients with "high risk" bladder cancer, only those who undergo BCG therapy following their TURBT will be eligible for enrollment.
• Subjects who receive BCG instillations post-operatively will be eligible for enrollment.
• Subjects whose tumors are AR(+) as well as AR(-) will be included, but we will restrict inclusion of AR(-) subjects so that they represent no more than 1/3 of the total study population, or any single cohort (ie. the intermediate or high-risk groups).
• Subjects of child-bearing potential must agree to 2 acceptable forms of birth control.

You may not qualify if…

• Subjects with "low risk" bladder cancer, as defined by the EAU guidelines21, will be ineligible for enrollment.
• Subjects with "high risk" bladder cancer who do not undergo BCG therapy following their TURBT will be ineligible for enrollment.
• Subjects who have "failed" BCG therapy in the past (had a recurrence of bladder cancer despite prior use of BCG) will be ineligible for enrollment.
• Subjects who receive an immediate post-TURBT single instillation of intravesical chemotherapy will be ineligible for enrollment.
• Subjects who receive a post-operative induction course of intravesical chemotherapy (ie. more than just a single immediate post-operative dose of intravesical chemotherapy) will be ineligible for enrollment.
• Subjects who undergo blue-light/fluorescence cystoscopy will be ineligible for enrollment.
• Subjects with a history of heart attack within the previous 12 months or who have unstable cardiovascular status will be ineligible for enrollment.
• Subjects who have uncontrolled hypertension (for our purposes, defined as those having a systolic blood pressure > 160 documented on 2 occasions despite appropriate medical therapy) will similarly be ineligible.
• Subjects with a history of venous thrombo-embolism (DVT/PE) within the past 3 years.
• Subjects with a history of seizure disorders, or those with a history of stroke or transient ischemic attacks (TIA) within the previous 12 months will be ineligible.
• Subjects with a history of liver disease whose hepatic enzymes, alkaline phosphatase or bilirubin are greater than twice the upper limit of normal will be ineligible.
• Subjects with kidney disease with an estimated glomerular filtration rate (eGFR) < 30 will be ineligible.
• Subjects with neutropenia will be ineligible.
• Subjects with clinical hypogonadism, those on androgen replacement therapy, or those with prostate cancer or other diseases treated with various forms of hormonal therapy (not including 5-alpha reductase inhibitors) will also be ineligible for study enrollment.
• Subjects who have undergone therapy for any malignancy within the past 5 years except for basal and squamous cell carcinomas of the skin will also be ineligible.
• Subjects with prior histories of prostate cancer treated by definitive local therapy > 5 years ago will only be eligible if they have had no clinical or biochemical evidence of recurrent prostate cancer.
