E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1. To compare bladder intact event-free survival in participants from Arm A (pembrolizumab + chemoradiotherapy) and Arm B (placebo + chemoradiotherapy), based on cystoscopy, biopsy with central pathology review (if applicable), urine cytology and radiographic assessment by blinded independent central review. |
|
E.2.2 | Secondary objectives of the trial |
1. To compare overall survival between Arm A (pembrolizumab + chemoradiotherapy) and Arm B (placebo + chemoradiotherapy). 2. To evaluate rate of metastasis-free survival. 3. To evaluate time to occurrence of non–muscle-invasive bladder cancer (NMIBC). 4. To evaluate the safety and tolerability of pembrolizumab + chemoradiotherapy. 5. To evaluate changes from baseline in health-related quality of life and time to deterioration, using 2 general instruments (European Organization for Research and Treatment of Cancer [EORTC] QoL questionnaire-Core 30 [QLQ-C30], and European Quality of Life [EuroQoL]-5 Dimensions, 5-level Questionnaire [EQ-5D-5L]) and one disease-specific instrument (Bladder Cancer Index [BCI]). 6. To evaluate time to cystectomy.

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Merck will conduct Future Biomedical Research on DNA (blood and tissue and others specimens collected during this clinical trial). Such research is for biomarker testing to address emergent questions not described elsewhere in the protocol (as part of the main trial) and will only be conducted on specimens from appropriately consented subjects. The objective of collecting specimens for Future Biomedical Research is to explore and identify biomarkers that inform the scientific understanding of diseases and/or their therapeutic treatments. The overarching goal is to use such information to develop safer, more effective drugs, and/or to ensure that subjects receive the correct dose of the correct drug at the correct time. |

E.3 | Principal inclusion criteria |
1. Has a histologically confirmed diagnosis of MIBC with predominant urothelial histology (histology and presence of muscle invasion to be confirmed by BICR) obtained via a diagnostic or maximal TURBT performed within 60 days prior to enrollment (signing of ICF). 2. Has clinically non-metastatic bladder cancer (N0M0) determined by imaging (CT of the chest and CTU/MRU of abdomen and pelvis), confirmed by BICR. 3. Has provided tumor specimen to the central vendor to determine PD-L1 status prior to randomization. 4. Has planned and is eligible to receive CRT and one of the protocol-specified radiosensitizing chemotherapy regimens. 5. Has an ECOG performance status of 0, 1, or 2 assessed within 7 days prior to randomization. 6. Demonstrates adequate organ function. All screening laboratory tests should be performed within 14 days prior to randomization. 7. Is male or female, at least 18 years of age, at the time of signing the informed consent. 8. Male participants are eligible to participate if they agree to the following during the intervention period and for at least 180 days after the last dose of study intervention. • Refrain from donating sperm PLUS either: • Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent OR • Must agree to use contraception unless confirmed to be azoospermic (vasectomized or secondary to medical cause) as detailed below: ◦ Agree to use a male condom plus partner use of an additional contraceptive method when having penile-vaginal intercourse with a WOCBP who is not currently pregnant. 9. A female participant is eligible to participate if she is not pregnant or breastfeeding, and at least one of the following conditions applies: - Is not a WOCBP OR - Is a WOCBP and using a contraceptive method that is highly effective (with a failure rate of <1% per year), with low user dependency, or be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis), during the intervention period and for at least 180 days after the last dose of study intervention and agrees not to donate eggs (ova, oocytes) to others or freeze/store for her own use for the purpose of reproduction during this period. The investigator should evaluate the potential for contraceptive method failure (ie, noncompliance, recently initiated) in relationship to the first dose of study intervention. - A WOCBP must have a negative highly sensitive pregnancy test (urine or serum, as required by local regulations) within 24 hours before the first dose of study intervention. - If a urine test cannot be confirmed as negative (eg, an ambiguous result), a serum pregnancy test is required. In such cases, the participant must be excluded from participation if the serum pregnancy result is positive. - The investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy. 10. The participant (or legally acceptable representative if applicable) provides written informed consent/assent for the study. The participant may also provide consent/assent for future biomedical research. However, the participant may participate in the main study without participating in future biomedical research. |
