Gemcitabine/Cisplatin Plus Cemiplimab With or Without Fianlimab in Localized Muscle-invasive Bladder Cancer (NeoSTOP-IT)
United States36 participantsStarted 2025-08-14
Plain-language summary
The goal of this clinical trial is to learn if gemcitabine/cisplatin plus cemiplimab with or without fianlimab works to treat bladder cancer in adults. The main question it aims to answer is: Can gemcitabine, cisplatin, and cemiplimab with or without fianlimab treat bladder cancer?
Participants will be randomly selected (like the loss of a coin) to treatment with gemcitabine, cisplatin, cemiplimab, and fianlimab or gemcitabine, cisplatin, and cemiplimab.
Participants will:
* Undergo transurethral resection of bladder tumor (TURBT) followed by the start of treatment, receive 4 cycles of treatment (21 day cycles)
* After 4 cycles of treatment, patients will undergo repeat maximal TURBT with imaging
* Participants with a complete response will continue maintenance cemiplimab or cemiplimab/fianlimab for 13 more cycles with imaging every 3 months
* Participants without a complete clinical response will undergo cystectomy (bladder surgery).

* Performance status of 0-1 using the Eastern Cooperative Oncology Group (ECOG) Performance Scale.
* Histologically confirmed muscle-invasive urothelial carcinoma of the bladder defined as T2-T3, N0, M0 stage. Mixed histology is permitted if there is a urothelial component. Upper tract disease in not permitted.
* Prior Bacillus Calmette-Guerin (BCG) or other intravesical treatment of non-muscle invasive bladder cancer is permitted if completed at least 6 weeks prior to initiating study treatment. Only one course (includes induction + maintenance) of BCG or intravesical therapy is permitted.
* No metastatic disease based on cross-sectional imaging.

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?

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?
