Ages Eligible for Study: | 20 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Patients who have provided written informed consent
-
Patients who have urothelial cell carcinoma of the bladder with clinically apparent stage Ta, grade G1-G2 and satisfy both of the following criteria:
- The maximum number of tumors is 5.
- Each tumor diameter: ≤ 3.5 cm.
- Age: ≥20 years old at enrollment.
-
The functions of the major organs are adequate, and the following test value criteria are satisfied:
- Neutrophil count ≥1,500/μL
- Platelet count ≥10×10^4/μL
- Hemoglobin ≥10 g/dL
Exclusion Criteria:
- Patients with a single, primary bladder cancer of <0.5 cm.
- Patients with CIS lesions in the bladder or a history thereof.
- Patients with a history of other than stage Ta, histological grade G1 or G2 disease.
- Patients experiencing recurrence within 4 months following TURBT for prior NMIBC (duration between the last TURBT and cystoscopic confirmation of the present recurrence is within 4 months).
- Patients without at least a three-month cystoscopically confirmed recurrence-free interval between the last TURBT and the time of study screening
- Patients having a bladder tumor with a histological diagnosis other than urothelial carcinoma of the bladder or a history thereof.
- Patients who had been administered EO9 in the past.
- Patients who had been administered any other investigational drug within the past 30 days.
- Patients having a medical condition that would make it unsafe for them to undergo TURBT under general or spinal anesthesia.
