A Study of Sasanlimab in People With Non-muscle Invasive Bladder Cancer
United States, Australia, Belgium1,068 participantsStarted 2019-12-30
Plain-language summary
The purpose of this study is to learn about the safety and effects of the study medicine (sasanlimab) in people with non-muscle invasive bladder cancer. This study is seeking participants whose bladder cancer is still in early stages, has not spread outside of the bladder, has been removed with surgery, and is high risk (Part A) or was previously treated with BCG (Bacillus Calmette Guerin), a standard treatment for bladder cancer (Part B).
In Part A (enrollment closed), each participant was assigned to one of three study treatment groups.
* One group is given sasanlimab and BCG at the study clinic.
* The second group is given sasanlimab and BCG at the study clinic. This group will receive BCG for the first six weeks only.
* The third group is given BCG only and will not receive sasanlimab.
In Part B of the study, each new participant will be assigned to a study treatment group based on the type of their bladder tumor.
\- Both groups will be given sasanlimab at the study clinic.
On August 31, 2022, the Sponsor announced the discontinuation of enrollment to Part B. The decision to discontinue enrollment to Part B was not made for safety reasons.

Inclusion Criteria:
* Histological confirmed diagnosis of high risk non-muscle invasive transitional cell carcinoma (TCC) of the urothelium of the urinary bladder (tumors of mixed transitional/non-transitional cell histology are allowed, but TCC must be the predominant histology)
* Complete resection of all Ta/T1 papillary disease (including participants with concurrent CIS), with most recent positive TURBT occurring within 12 weeks prior to randomization or study intervention. A second TURBT must have been performed if indicated according to the current locally applicable guidelines, ie, American Urological Association, European Association of Urology
* (Cohorts B1 and B2 only): Histological confirmed diagnosis of BCG-unresponsive high-risk, non-muscle invasive TCC of the urothelium within 12 months (CIS only) or 6 months (recurrent Ta/T1 disease) of completion of adequate BCG therapy.
* Have refused or are ineligible for radical cystectomy
Exclusion Criteria:
* Evidence of muscle-invasive, locally advanced or metastatic urothelial cancer or concurrent extravesical, non-muscle invasive TCC of the urothelium
* (Cohort A only): Intravesical BCG therapy within 2 years prior to randomization. Prior intravesical chemotherapy for NMIBC is allowed.
(Cohorts B1 and B2 only): Any systemic or intravesical chemotherapy or immunotherapy from the time of most recent positive TURBT to initiation of study intervention.
* Prior immunotherapy with anti PD-1, anti PD-L1, anti PD-L2, or a…
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?
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

Cohort A: Event Free Survival (EFS) as Assessed by the Investigator: Arm A Versus Arm C
Timeframe: From randomization (Day 1) to first documentation of high-grade disease, progression of disease, persistence of CIS or death due to any cause, whichever occurred first (maximum follow up duration was up to 257.1 weeks)
