NCT05825950

Brief Summary

This is a multi-center study and the aim is to develop and validate an Artificial Intelligence (AI) -based histologic analysis tool to predict responsiveness to intravesical Bacillus Calmette-Guérin (BCG) and intravesical chemotherapy in intermediate and high-risk non-muscle invasive bladder cancer patients.

Outcome Measures

Primary Outcomes (4)

  • Recurrence free survival (RFS) at 3 months after TURBT in participants with HR NMIBC

    Recurrence free survival (RFS) is measured as the time from start of clinical treatment / study enrollment to the date of first procedure confirming histopathological recurrence, disease progression or death as a first event from any cause during surveillance cystoscopy at 3 months.

    3 months

  • Recurrence free survival (RFS) at 6 months after TURBT in patients with HR NMIBC

    Recurrence free survival (RFS) is measured as the time from start of clinical treatment / study enrollment to the date of first procedure confirming histopathological recurrence, disease progression or death as a first event from any cause during surveillance cystoscopy at 6 months.

    6 months

  • Recurrence free survival (RFS) at 12 months after TURBT in patients with HR NMIBC

    Recurrence free survival (RFS) is measured as the time from start of clinical treatment / study enrollment to the date of first procedure confirming histopathological recurrence, disease progression or death as a first event from any cause during surveillance cystoscopy at 12 months.

    12 months

  • Recurrence free survival (RFS) at 24 months after TURBT in patients with HR NMIBC

    Recurrence free survival (RFS) is measured as the time from start of clinical treatment / study enrollment to the date of first procedure confirming histopathological recurrence, disease progression or death as a first event from any cause during surveillance cystoscopy at 24 months.

    24 months

Secondary Outcomes (6)

  • Recurrence free survival (RFS) at 3 months following the first negative surveillance cystoscopy after TURBT in patients with IR NMIBC

    3 months

  • Recurrence free survival (RFS) at 6 months following the first negative surveillance cystoscopy after TURBT in patients with IR NMIBC

    6 months

  • Recurrence free survival (RFS) at 12 months following the first negative surveillance cystoscopy after TURBT in patients with IR NMIBC

    12 months

  • Recurrence free survival (RFS) at 24 months following the first negative surveillance cystoscopy after TURBT in patients with IR NMIBC

    24 months

  • Progression-free survival (PFS) at 12 months following the first negative surveillance cystoscopy after TURBT in patients with HR or IR NMIBC

    12 months

Study Arms (2)

HR NMIBC group

High Risk (HR) NMIBC group of participants studied include ones with American Urological Association (AUA) / Society of Urologic Oncology (SUO) criteria such as : high grade T1, recurrent high grade Ta, high grade Ta \>3 cm, multifocal high grade Ta, any Carcinoma in-situ (CIS), any BCG failure in high grade disease, any variant histology, any lymphovascular invasion. Note: Ta means the cancer is just in the innermost layer of the bladder lining. T1 means the cancer has started to grow into the connective tissue beneath the bladder lining.

IR NMIBC group

Intermediate Risk (IR) NMIBC group of participants studied include ones with AUA/SUO criteria such as : recurrence within 1 year low grade Ta, solitary low grade Ta \>3 cm, multifocal low grade Ta, high grade Ta ≤3 cm, low grade T1 Note: Ta means the cancer is just in the innermost layer of the bladder lining. T1 means the cancer has started to grow into the connective tissue beneath the bladder lining.
