Eligibility Criteria

Age18 Years+
Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Males, age 18 or greater.
  • Patients with histologically confirmed non-muscle invasive urothelial carcinoma.
  • Patients have been recommended for a course of intravesical BCG induction treatment by their urologist
  • Patients who received gemcitabine, epirubicin or mitomycin C instillations immediately post-operatively will be eligible for enrollment.
  • Patients with partners of child-bearing potential must agree to 2 acceptable forms of birth control and be continued for at least 3 months after study drug is discontinued.

You may not qualify if:

  • Patients who have received induction BCG therapy within the last 5 years will be ineligible for enrolment.
  • Patients with a history of myocardial infarction or hospital admission for heart failure within the previous 12 months or who have unstable cardiovascular status will be ineligible for enrolment.
  • Patients 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.
  • Patients 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.
  • Patients with clinical hypogonadism, those on androgen replacement therapy, or those with prostate cancer or other diseases treated with systemic hormonal therapy will be ineligible for study enrolment. Patients receiving 5ARIs will not be excluded.
  • Patients who have cancer treatment ongoing or planned in the near future which can be anticipated to decrease their 2-year survival or BCa treatment plan will be ineligible.
  • Patients taking an investigational drug within 2 weeks of enrolment into this study will be ineligible.
  • Patients receiving or planning to receive coumadin therapy will be ineligible.
