Plain-language summary
This phase II trial tests whether sacituzumab govitecan given before radical cystectomy works in treating patients with non-urothelial bladder cancer. Sacituzumab govitecan contains a monoclonal antibody, called sacituzumab, linked to a chemotherapy drug, called govitecan. Sacituzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as TROP2 receptors, and delivers govitecan to kill them. Giving sacituzumab govitecan before radical cystectomy may make the surgery more effective in patients with muscle invasive bladder cancer.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Participants must be at least 18 years of age on the day of signing informed consent. Participant (or legally acceptable representative if applicable) provides written informed consent for trial
* Participants must have either histologically or by clinical consensus (based on imaging and/or exam under anesthesia) confirmed diagnosis of muscle invasive bladder cancer (cT2-T4aN0-N1M0 or cT1-4aN1M0 clinical stage per American Joint Commission on Cancer \[AJCC\]). Patients with clinical node-positive (N1) stage are eligible provided the lymph node (LN) is confined to the true pelvis and is within the planned surgical LN dissection template; cN1 is defined as a lymph node with \>= 15 mm short axis or biopsy-positive for carcinoma
* Must have clinical non-metastatic bladder cancer (M0) determined by cross-sectional Computed tomography (CT) chest, abdomen and pelvis (CAP) or magnetic resonance imaging (MRI)
* Review of pathology by local expert genitourinary (GU) pathologist is required. Any component (%) of non-conventional urothelial (variant histology) noted on transurethral resection of bladder tumour (TURBT) is allowed, for histologic types not listed below. However, for the variant histologic types listed below, the following parameters need to be met:
* Squamous cell carcinoma / squamous cell features need to be pure or predominant (\>= 1 variant histologic with total non-conventional urothelial component \> 50%).
* Adenocarcinoma / glandular featu…
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.
