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.

Plain-language summary
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.

Inclusion criteria
. Patients with current CIS of the bladder, with or without coexisting papillary Ta/T1 NMIBC tumor(s), who experienced an occurrence or recurrence of CIS within 12 months of completion of adequate BCG7 therapy. An adequate BCG regimen shall consist of at least 2 courses of BCG where the first course (induction) must have included at least 5 of 6 weekly treatments and the second course may have included a re-induction (at least 2 of 6 treatments) or maintenance, (at least 2 of 3 treatments) administered on a schedule similar to the SWOG 8507 study regimen.
. All clinical, intra-operative and pathological items for the AUA risk stratification must be documented. This includes bladder mapping, according to the instructions specified in the protocol. With regard to BCG and/or other NMIBC treatments documentation must include:
. Date of initial treatment,
. Date of last treatment,
. The number of courses administered and the number of treatments administered in each course.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
complete response rate (CRR)
Timeframe: 3 months after the initiation of study therapy
. Patients with concomitant papillary tumor(s) must have undergone a repeat TUR 2-4 weeks prior to the first study treatment:
. if the previous TUR was incomplete,
. if there was no muscle in the specimen after the initial TUR (except in TaLG tumors),
Exclusion criteria
. Non-UC tumor of the urinary tract.
. Upper tract and/or intramural tumors (e.g., in ostium).
. Positive selective cytology from the upper tract.
. History of stage \> T1 UC.
. Papillary tumors \> T1 in repeat TUR.
. Known or suspected reduced bladder capacity. Patients will have an ultrasonic estimation of maximum bladder capacity or void spontaneously the maximum they can retain in their bladder, and this will be used to determine urine volume. A minimum volume of 250 ml is required.
. Patients with severe bladder outlet obstruction not adequately controlled with medication (AUA symptom score ≥ 20).
