Study Endpoints
Primary Endpoints
Disease- Free Survival (DFS)
Up to ~78 months

DFS is defined as the time from randomization to any recurrence (local, locoregional, regional or distant), occurrence of new primary NSCLC, as assessed by the investigator, or death due to any cause, whichever occurs first.

Recurrence-Free Survival (RFS)
Up to approximately 74 months

RFS is defined as the length of time from when the participant starts the study until either the cancer comes back, or the cancer spreads as assessed by the investigator, or death due to any cause.

Progression Free Survival (PFS)
Up to ~32 months

PFS is defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurs first as assessed by Response Criteria in Solid Tumors Version 1.1 (RECIST 1.1). PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions is also considered PD. PFS as assessed by blinded independent central review (BICR) will be presented.

Overall Survival (OS)
Up to ~42 months

OS, defined as the time from randomization to death due to any cause. OS will be presented.

Progression-free Survival (PFS)
Up to approximately 36 months

PFS is defined as the time from randomization to the first documented disease progression per Response Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by investigator assessment or death due to any cause, whichever occurs first. Progressive disease (PD) is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions is also considered PD. PFS per RECIST 1.1 as assessed by investigator will be presented.

Cohort A: Event-free Survival (EFS)
Up to approximately 5 years

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.

Disease-Free Survival (DFS)
up to ~43 months

DFS, as assessed by the investigator, is defined as the time from randomization to the first documented local recurrence, or occurrence of distant kidney cancer metastasis(es), or death due to any cause, whichever occurs first.

Overall Survival (OS)

Intismeran autogene + PembrolizumabEXPERIMENTALParticipants will receive 1 mg of intismeran autogene via intramuscular (IM) injection once every 3 weeks for 9 doses PLUS 400 mg of pembrolizumab via intravenous (IV) infusion once every 6 weeks for up to 9 doses until disease recurrence or unacceptable toxicity or for a total treatment duration of up to approximately 1 year, whichever is sooner.
Placebo + PembrolizumabACTIVE_COMPARATORParticipants will receive intismeran autogene-matched placebo via IM injection once every 3 weeks for 9 doses PLUS 400 mg of pembrolizumab via IV infusion once every 6 weeks for up to 9 doses until disease recurrence or unacceptable toxicity or for a total treatment duration of up to approximately 1 year, whichever is sooner.
Intismeran Autogene + Pembrolizumab + ChemoEXPERIMENTALInduction phase: Participants receive pembrolizumab 400 mg intravenous (IV) infusion on Day 1 of a six week cycle plus a platinum doublet chemotherapy regimen (carboplatin area under the curve (AUC) 6 or 5 mg/mL/min IV infusion every 3 weeks (Q3W) × 2 doses combined either with paclitaxel 200 or 175 mg/m\^2 IV infusion Q3W × 2 doses, OR with nab paclitaxel 100 mg/m\^2 IV infusion weekly × 6 doses). Intismeran Autogene 1 mg intramuscular (IM) injection is administered on Days 1 and 22 of Cycle 2 Induction (Q3W) for up to 2 doses. Maintenance phase: Participants receive pembrolizumab 400 mg IV infusion on Day 1 every 6 weeks (Q6W) for up to 15 doses. Intismeran Autogene 1 mg IM injection is administered on Days 1 and 22 (Q3W) for up to 7 doses during maintenance.
Placebo + Pembrolizumab + ChemoEXPERIMENTALInduction phase: Participants receive pembrolizumab 400 mg intravenous (IV) infusion on Day 1 of a six week cycle plus a platinum doublet chemotherapy regimen (carboplatin area under the curve (AUC) 6 or 5 mg/mL/min IV infusion every 3 weeks (Q3W) × 2 doses combined either with paclitaxel 200 or 175 mg/m\^2 IV infusion Q3W × 2 doses, OR with nab paclitaxel 100 mg/m\^2 IV infusion weekly × 6 doses). Placebo intramuscular (IM) injection is administered on Days 1 and 22 of Cycle 2 Induction (Q3W) for up to 2 doses. Maintenance phase: Participants receive pembrolizumab 400 mg IV infusion on Day 1 every 6 weeks (Q6W) for up to 15 doses. Placebo IM injection is administered on Days 1 and 22 (Q3W) for up to 7 doses during maintenance.
Intismeran autogene + BCGEXPERIMENTALParticipants in Cohort A receive 1 mg of intismeran autogene via intramuscular (IM) injection every 3 weeks (Q3W) for 9 doses. Participants also receive 50 mg of TICE® BCG once weekly for 6 weeks, then once weekly on weeks 13-15, 25-27, 49-51, and 73-75.
