Mitomycin C Intravesical Chemotherapy in Conjunction With Synergo® Radiofrequency-Induced Hyperthermia for Treatment of Carcinoma in Situ Non-Muscle Invasive Bladder Cancer Patients Unresponsive to Bacillus Calmette-Guérin, With or Without Papillary Tumors.

This study will determine whether Synergo® RITE + MMC treatment is efficacious as second-line therapy for CIS NMIBC BCG-unresponsive patients with or without papillary NMIBC, through examination of the complete response rate (CRR) and disease-free duration for complete responders. The study will also explore progression-free survival time, bladder preservation rate, and overall survival time. The study will address an unmet need to identify a treatment effective in both ablating the disease and providing a prolonged disease-free period for patients. Ideally, the treatment will delay progression to invasive disease, thus preserving the bladder.
