This study is designed to assess the antitumor efficacy and safety of pembrolizumab in combination with chemoradiotherapy (CRT) versus CRT alone in participants with muscle-invasive bladder cancer (MIBC). The primary hypothesis is that pembrolizumab + chemoradiotherapy is superior to placebo + chemoradiotherapy with respect to bladder intact event-free survival.

All Sponsor personnel will be blinded to treatment assignments, with the exception of designated unblinded team members. Chemoradiotherapy will be administered to all participants and will be open-label.

Efficacy and Safety of Pembrolizumab (MK-3475) in Combination With Chemoradiotherapy (CRT) Versus CRT Alone in Muscle-invasive Bladder Cancer (MIBC) (MK-3475-992/KEYNOTE-992)

A Phase 3, Randomized, Double-blind, Placebo-controlled Clinical Trial to Study the Efficacy and Safety of Pembrolizumab (MK-3475) in Combination With Chemoradiotherapy (CRT) Versus CRT Alone in Participants With Muscle-invasive Bladder Cancer (MIBC) (KEYNOTE-992)

BI-EFS is defined as the time from randomization to any of the following events: residual/recurrent MIBC post-chemoradiotherapy (CRT), nodal or distant metastases as assessed by computerized tomography (CT) and CT urography (CTU) or magnetic resonance urography (MRU) per blinded independent central review (BICR) and/or biopsy results assessed by central pathology review, radical cystectomy, or death due to any cause. If biopsy is not feasible due to participant safety, the imaging alone will be sufficient. The BI-EFS for all participants will be presented.

Time from randomization to death due to any cause.

MFS is defined as the time from randomization to the first documented occurrence of nodal or distant metastases as assessed by CT and CTU or MRU per BICR and/or biopsy results assessed by central pathology review If biopsy is not feasible due to participant safety, the imaging alone will be sufficient.

Time to occurrence of low-grade disease, defined as the time from randomization until the development of NMIBC, will be presented.

An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants who experience an AE will be presented.

An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants who discontinue study treatment due to an AE will be presented.

The EORTC-QLQ-C30 is a 30-item questionnaire developed to assess the quality of life of cancer patients. Participant responses to the questions "How would you rate your overall health during the past week?" and "How would you rate your overall quality of life during the past week?" are scored on a 7-point scale (1=Very Poor to 7=Excellent). A higher score indicates a better overall outcome. The change from baseline in Global Health Status/Quality of Life (EORTC QLQ-C30 Items 29 and 30) combined score will be presented.

EORTC-QLQ-C30 is a 30-item questionnaire developed to assess the quality of life of cancer patients. Participant responses to 5 questions about their physical functioning are scored on a 4-point scale (1=Not at All to 4=Very Much). A higher score indicates a better quality of life. The change from baseline in Physical Functioning (EORTC QLQ-C30 Items 1-5) combined score will be presented.

The BCI is a validated, condition-specific health questionnaire assessing quality of life among participants with bladder cancer. The BCI contains 36 items which assess 3 domains (urinary, bowel, and sexual) with function and bother subdomains. Scores range from 0 to 100 with higher scores corresponding to better functioning and health-related quality of life. The change from baseline in the combined scores of the urinary, bowel, and sexual domains of the BCI will be presented.

The EQ-5D-5L VAS records the respondent's self-rated health on a 10 cm vertical, visual analogue scale. It is rated by the respondent on a scale 0 to 100, with 0 being "the worst health you can imagine" and 100 being "the best health you can imagine". The change from baseline in EQ-5D-5L VAS will be presented.

Participant responses to the questions "How would you rate your overall health during the past week?" and "How would you rate your overall quality of life during the past week?" are scored on a 7-point scale (1=Very Poor to 7=Excellent). A higher score indicates a better overall outcome. TTD in Global Health Status/Quality of Life is defined as the time from baseline to the first onset of a 10 point or greater decrease from baseline in the Global Health Status/Quality of Life (EORTC QLQ-C30 Items 29 and 30) combined score, with or without subsequent confirmation.

Participant responses to 5 questions about their physical functioning are scored on a 4-point scale (1=Not at All to 4=Very Much). A higher score indicates a better quality of life. TTD in Physical Functioning (EORTC QLQ-C30 Items 1-5) combined score is defined as the time from baseline (at randomization) to the first onset of a ≥10-point decrease with confirmation by the subsequent visit of a ≥10-point decrease in physical functioning Items 1 to 5 scale scores.

The BCI is a validated, condition-specific health questionnaire assessing quality of life among participants with bladder cancer. The BCI contains 36 items which assess 3 domains (urinary, bowel, and sexual) with function and bother subdomains. Scores range from 0 to 100 with higher scores corresponding to better functioning and health-related quality of life. TTD in BCI is defined as a 6, 7, and 7 points or greater worsening from baseline for urinary, bowel, and sexual domains, respectively, with or without subsequent confirmation, under a right-censoring rule.

The EQ-5D-5L VAS records the respondent's self-rated health on a 10 cm vertical, visual analogue scale. It is rated by the respondent on a scale 0 to 100, with 0 being "the worst health you can imagine" and 100 being "the best health you can imagine". TTD in EQ-5D-5L VAS is defined as the time from baseline to the first onset of a 7 point or greater decrease from baseline in EQ-5D-5L VAS, with or without subsequent confirmation, under a right-censoring rule.

Time to cystectomy is defined as time from a participant's randomization to date of cystectomy.
