Primary Outcome Measures:
  • To evaluate the recurrence rate at 2 years in randomized patients with tumor histology Ta, G1-G2 who receive TUR-BT plus EOquin® versus those who receive TUR-BT plus placebo. [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To evaluate time to first recurrence in patients with tumor histology Ta, G1-G2 who receive TUR-BT plus EOquin® versus those who receive TUR-BT plus placebo. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • To evaluate progression to higher stage or grade, number of recurrences per patient, disease free interval, disease free survival and overall survival. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • To assess the safety of EOquin instilled into the bladder in the early postoperative period. [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]

Detailed Description:

This is a multicenter, randomized, placebo-controlled, double-blind, study. Following TUR-BT, eligible patients will be randomized to receive either intravesical EOquin® (Apaziquone) or matching placebo instilled within 6 hours of surgery. Patients will be seen for a postoperative follow-up exam 21±10 days after the TUR. At this time, the pathology report will be reviewed. If the histology of the patient's tumor is Ta, G1-G2 (low grade [WHO/ISUP classification]), then the patient will receive no further treatment and will be observed cystoscopically every three months through year two for tumor recurrence and progression. If the histology of the patient's tumor is other than Ta, G1-G2 (low grade [WHO/ISUP classification]), then the patient will receive further treatment in accordance with current treatment guidelines, following which the patient will be followed up cystoscopically every three months through year two for tumor recurrence and progression.

  5. If the patient is a female of childbearing potential, has she had a negative serum pregnancy test within the past 14 days?
  6. Is the patient willing and able to abide by the protocol?

Exclusion Criteria:

All of the following questions must be answered "No" in order for the patient to participate in the study.

  1. Does the patient have more than 5 bladder tumors?
  2. Does any single bladder tumor exceed 3.5 cm in diameter?
