Bladder Cancer | Drug: Apaziquone Drug: Placebo Procedure: TURBT | Phase 3 |
This was a Phase 3, multicenter, randomized, double-blind, placebo-controlled study. Within 14 days of Screening, eligible patients underwent a TURBT during Visit 1 (Day 0) following which they were immediately randomized in a 1:1 ratio to receive either placebo or 4 mg apaziquone, instilled in a volume of 40 mL into the bladder within 6 hours from the end of the TURBT procedure. After a 60-minute retention period, study drug was drained from the bladder.
A postoperative follow-up examination and review of the local pathology report were performed at Visit 2, which occurred 21 days (±10 days) after the TURBT (Week 3).
- If the histology of the patient's tumor was confirmed as Ta, G1-G2 (ie, low grade according to World Health Organization [WHO]/International Society of Urologic Pathology [ISUP] classification), no further treatment was given and the patient was observed cystoscopically every 3 months through Year 2 for tumor recurrence (Visit 3 through Visit 10).
- If the histology of the patient's tumor was other than Ta, G1 or G2 (low grade [WHO/ISUP classification]), further treatment was given in accordance with current treatment guidelines, and the patient was followed up cystoscopically every 3 months through Year 2 for tumor recurrence (Visit 3 through Visit 10).
All patients were to be followed for 2 years.
