Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Patients who have provided written informed consent

  2. 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.
  3. Age: ≥20 years old at enrollment.

  4. 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:

  1. Patients with a single, primary bladder cancer of <0.5 cm.
  2. Patients with CIS lesions in the bladder or a history thereof.
  3. Patients with a history of other than stage Ta, histological grade G1 or G2 disease.
  4. 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).
  5. Patients without at least a three-month cystoscopically confirmed recurrence-free interval between the last TURBT and the time of study screening
  6. Patients having a bladder tumor with a histological diagnosis other than urothelial carcinoma of the bladder or a history thereof.
  7. Patients who had been administered EO9 in the past.
  8. Patients who had been administered any other investigational drug within the past 30 days.
  9. Patients having a medical condition that would make it unsafe for them to undergo TURBT under general or spinal anesthesia.

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
