Pre-TURBT TC-3 Gel Intravesical Instillation in NMIBC
This trial is active, not recruiting.
|Condition||carcinoma of urinary bladder, superficial|
|Treatments||40 mg mmc gel, standard of care mmc mixed with water, 80 mg mmc gel|
|Sponsor||UroGen Pharma Ltd.|
|Start date||June 2013|
|End date||July 2016|
|Trial size||80 participants|
|Trial identifier||NCT01803295, TAS-4M-CS-0002-0|
In the proposed study the investigators aim to evaluate the effect of the standard of care dose (40mg) of MMC mixed with TC-3 gel (with sustained release mechanism on the drug) on low risk recurrent NMIBC lesions and to compare our findings to instillation with the standard mode of instillation- 40mg MMC in water in order to examine our hypothesis that MMC mixed with TC-3 gel will have at least non-inferior and even superior results over the standard instillation mode
The investigators believe that this study is of importance of several aspects:
1. It evaluates a new mode of bladder instillation that may bypass the drawbacks of the current instillation mode.
2. If proved effective this mode of treatment might save the need of TURBT performance and serve as a new mode of tumor ablation.
3. Even if proved partially effective this mode of treatment will diminish tumors size or number thus enable a more limited TURBT procedure.
4. This mode of treatment will enable immediate medical attendance to the patient's tumor recurrence without the waiting period (resulting from queues in the medical centers) for TURBT, which might improve the patient's prognostic outcome.
5. If this experimental treatment will prove to have a better ablative effect, this could be translated to a better prophylactic effect of tumor recurrence.

|Official title||Evaluating the Effect of Pre-TURBT Intravesical Instillation of Mitomycin C (MMC) Mixed With TC-3 Gel in Patients With Non Muscle Invasive Bladder Cancer (NMIBC)|
|Principal investigator||Fred Witjes, Prof|
|Description||Non-muscle-Invasive Bladder cancer is mainly treated by tumor resection (Trans Urethral Resection - TUR), followed by series of intravesical instillations of prophylactic chemotherapeutic drugs as Mitomycin C (MMC) or BCG. This treatment approach is limited due to rapid dilution the chemotheraputic drug by the incoming urine and clearance by urination. TheraCoat core technology is based on a reverse thermal biodegradable gel (TC-3) (low viscosity at 5°C gel appearance at body temperature)for drug retention in the urinary bladder. Prior to instillation, the TC-3 hydrogel, in a liquid state, is mixed with MMC.TC-3 mixed with MMC is instilled to the bladder by a catheter. Following gel insertion to the bladder, the gel solidifies and forms a drug reservoir inside the bladder. Upon contact with urine the gel dissolves and is cleared out from the bladder. Intravesical MMC instillation using TheraCoat gel is expected to increase treatment efficiency due to prolongation of treatment duration and consequently improving bladder exposure to MMC. Treatment Protocol - Immediately following baseline cystoscopy and tumor diagnosis and patient undergoes 6 weekly instillations followed by 2-4 weeks healing period. 1st Follow-Up Visit (Pre-Scheduled TURBT Visit): The patient will undergo a second Cystoscopy to compare to the Baseline status and after that a follow-up period: 3,6,9,12 months.|
