About this trial
Researchers are looking for new ways to treat people with high-risk non-muscle invasive bladder cancer (HR NMIBC). NMIBC is cancer in the tissue that lines the inside of the bladder but has not spread to the bladder muscle or outside of the bladder. High-risk means NMIBC may have a high chance of getting worse or coming back after treatment. HR NMIBC can also include carcinoma in situ (CIS). CIS is bladder cancer that appears flat and is only in the inner layer (surface) of the bladder. CIS is not raised and is not growing toward the center of the bladder.
The standard treatment for HR NMIBC is a procedure to remove the tumor called transurethral resection of the bladder tumor (TURBT) followed by Bacillus Calmette-Guerin (BCG). Standard treatment is something that is considered the first line of treatment for a condition. BCG is an immunotherapy, which is a treatment that helps the immune system fight cancer. However, BCG may not work to treat HR NMIBC in some people. Researchers want to learn if adding intismeran autogene, the study treatment, to standard treatment can help treat HR NMIBC. Intismeran autogene is designed to help a person's immune system attack their specific cancer.
The goal of this study are to learn if people who receive V940 with BCG live longer and without the cancer growing, spreading, or coming back compared to people who receive BCG alone.

Trial outcomes
Primary outcomes
Cohort A: Event-free Survival (EFS)
EFS is defined as the time from randomization to any of the following events, as determined by blinded independent central review (BICR): High-grade (HG) non-invasive papillary carcinoma (Ta) or carcinoma in situ (CIS) in the bladder at the 24-week assessment or later; Any T1 stage disease in the bladder; Any T2 stage or greater in the bladder, including transurethral prostate stromal invasion of urothelial carcinoma (UC); High-risk disease (defined as HG Ta, CIS, ≥T1) of the urethra or upper tract (ureters, renal pelvis); Metastatic UC \[defined as regional lymph node metastasis of UC (stage N1 or greater), or distant metastasis of UC including non-regional lymph nodes (stage M1)\]; Or death due to any cause. The EFS for BCG-treated participants will be presented.
Secondary outcomes
Cohort A: 12-Month Event-free Survival (EFS)
EFS is defined as the time from randomization to any of the following events, as determined by BICR where applicable: HG Ta or CIS in the bladder at the 24-week assessment or later; Any T1 stage disease in the bladder; Any T2 stage or greater in the bladder, including transurethral prostate stromal invasion of UC; High-risk disease (defined as HG Ta, CIS, ≥T1) of the urethra or upper tract (ureters, renal pelvis); Metastatic UC \[defined as regional lymph node metastasis of UC (stage N1 or greater), or distant lymph node or visceral metastasis of UC (stage M1)\]; Or death due to any cause. The EFS at 12 months for BCG-treated participants will be presented.
Cohort A: 24-Month Event-free Survival (EFS)
EFS is defined as the time from randomization to any of the following events, as determined by BICR where applicable: HG Ta or CIS in the bladder at the 24-week assessment or later; Any T1 stage disease in the bladder; Any T2 stage or greater in the bladder, including transurethral prostate stromal invasion of UC; High-risk disease (defined as HG Ta, CIS, ≥T1) of the urethra or upper tract (ureters, renal pelvis); Metastatic UC \[defined as regional lymph node metastasis of UC (stage N1 or greater), or distant lymph node or visceral metastasis of UC (stage M1)\]; Or death due to any cause. The EFS at 24 months for BCG-treated participants will be presented.
Cohort A: Recurrence-free Survival (RFS)
RFS is defined as the time from randomization to any of the following events, as determined by BICR where applicable: HG Ta or CIS in the bladder at the 24-week assessment or later; Any T1 stage disease in the bladder; Any T2 stage or greater in the bladder, including transurethral prostate stromal invasion of UC; High-risk disease (defined as HG Ta, CIS, ≥T1) of the urethra or upper tract (ureters, renal pelvis); Metastatic UC \[defined as regional lymph node metastasis of UC (stage N1 or greater), or distant lymph node or visceral metastasis of UC (stage M1)\]; Death due to any cause; or any other UC recurrence including low-grade (LG) Ta at any timepoint as well as HG Ta or CIS in the bladder before the 24-week assessment. The RFS will be presented.
Cohort A: Disease-specific Survival (DSS)
DSS is defined as the time from randomization to death due to bladder cancer. The DSS will be presented.
