A Randomized, Multicenter, Two-ARM, Single-Dose, Double-Blind, Placebo-Controlled Phase 3 Study of Intravesical Qapzola (Apaziquone) as a Chemotherapy Adjuvant to TransUrethral Resection of Bladder Tumors in Patients with Low-to Intermedicate-Risk Non-Muscle Invasive Bladder Cancer (CONQUER)
The primary purpose of the study is to gather information on an investigational study drug called apaziquone. If you choose to take part in this study, this study drug would be given to you after you have had bladder tumor surgery.
Apaziquone (Qapzola) is an investigational, anti-cancer drug known as a bio-reductive alkylating indoloquinone which is thought to cause cell death. Early studies in humans have shown apaziquone has some anti-cancer activity that may prevent or delay the return of bladder cancer following surgery.
The standard of care for bladder cancer is to surgically remove the tumors through surgery. This is known as a transurethral resection of bladder tumor (TURBT). However, bladder cancer often comes back, even after surgery. This study is to determine if giving apaziquone right after the surgery will decrease the risk of the cancer coming back.
One dose of either Qapzola or placebo(a substance that has no therapeutic effect) will be administered into the bladder after the transurethral resection of bladder tumor(TURBT) is completed and this will be instilled through an indwelling foley catheter and will be retained in the bladder for 60 minutes.
