<p>Cystoscopic and pathological effect (evaluated at TUR-BT visit) of pre-TURBT<br /><br>intravesical instillations with 40mg of MMC mixed with 60cc TC-3 Hydrogel on<br /><br>bladder lesion(s) of NMIBC patients.<br /><br><br /><br>Demonstration of Pre-TURBT TC-3 gel-MMC instillation safety and adverse event<br /><br>rate.<br /><br><br /><br>(pag 22-24 of the protocol)</p><br>
Secondary Outcome Measures
NameTimeMethod
<p>Comparison of the cystoscopic and pathological effect of pre-TURBT<br /><br>instillations with MMC mixed with TC-3 Hydrogel on bladder lesion(s) to that of<br /><br>pre-TURBT MMC in water instillation.<br /><br><br /><br>Comparison of one year tumor recurrence rate between both treatment groups.<br /><br><br /><br>Demonstration that blood levels of MMC following Pre-TURBT TC-3 gel-MMC<br /><br>instillation are below the toxic level (400ng/ml) known in the art for IV MMC<br /><br>administration..<br /><br><br /><br>(pag 25 of the protocol)</p><br>
