Criteria

INCLUSION CRITERIA:

NOTE: Both patients who will and will not receive standard of care concomitant mitomycin C are eligible to enroll in this study.

• Ability to understand and the willingness to sign a written informed consent

• Diagnosis of presumed non-muscle invasive bladder cancer based on office based cystoscopy (primary or recurrent), and planned transurethral resection of bladder tumor (TURBT)

• Participants must have tumors with anticipated transurethral resection time ≤ 1 hour

• Previous history of intravesical therapy allowed

• Age ≥ 18 years

• Performance Status 0-1

• Adequate organ and marrow function as defined below:

• leukocytes ≥ 3,000/mcL

• absolute neutrophil count ≥ 1,500/mcL

• platelets ≥ 100,000/mcl

• total bilirubin within normal institutional limits

• Aspartate Aminotransferase (AST) ≤ 2.5 X institutional upper limit of normal

• Alanine Aminotransferase (ALT) ≤ 2.5 X institutional upper limit of normal

• creatinine ≤ 2.5 X institutional upper limit of normal

• Women of child-bearing potential (WOCP) and men with partners of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 90 days following completion of therapy. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately *A woman of child-bearing potential is any female (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria:

• Has not undergone a hysterectomy or bilateral oophorectomy; or

• Has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months)

EXCLUSION CRITERIA:

Participants meeting any of the exclusion criteria at baseline will be excluded from study participation.

• Current or anticipated use of other investigational agents.

• Patient has known nodal or distant metastatic disease. Patients with nodal or metastatic disease require systemic chemotherapy. Furthermore, they should be excluded from this clinical trial because of their poor overall prognosis.

• Patients with locally advanced bladder cancer based on cross-sectional imaging (suspicion of extravesical disease or hydronephrosis)

• Patients with tumors with anticipated transurethral resection time greater than 1 hour

• History of allergic reactions attributed to compounds of similar chemical or biologic composition to Ethacrynic acid or other agents used in study.

• Systolic blood pressure < 90 mmHg and/or diastolic blood pressure < 50 mmHg

• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

• Pregnant or nursing. There is a potential for congenital abnormalities and for this regimen to harm nursing infants.
