Inclusion criteria
. Are aged 18 years or older;
. Have a history of pathologically confirmed high-grade Ta or T1 NMIBC without CIS who have completed SOC previously, with recurrent papillary disease seen on cystoscopy, and who are undergoing TURBT without perioperative intravesical chemotherapy;
. Are considered high risk for recurrence;
. Have Eastern Cooperative Oncology Group (ECOG) Performance Status of 0, 1, or 2;
. Have adequate organ and marrow function as defined below:
Exclusion criteria
. Have a history of CIS or MIBC;
. Are receiving any other investigational agents;
. Have a history of allergic reactions attributed to compounds of similar chemical or biologic composition to resiquimod (R848), or excipients used in STM-416 including poloxamer 407 and sodium hyaluronate;
. Have an uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
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
Incidence of dose-limiting toxicities (DLTs) [Safety and Tolerability] Phase 1
Timeframe: 21 days
2
Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] Phase 1
Timeframe: Time on trial up to 90 days
3
Recurrence free survival time (Phase 2a)
Timeframe: Through study completion up to 24 months
. Are a woman of childbearing potential regardless of contraceptive use; Note: Women of childbearing potential are only to be excluded in Phase 1 and Phase 2a to avoid bias due to the low prevalence of NMIBC in this population. However, they will be included in subsequent Phase 2/3 studies.
