Study of Pembrolizumab/Vibostolimab (MK-7684A) in Combination With Concurrent Chemoradiotherapy Followed by Pembrolizumab/Vibostolimab Versus Concurrent Chemoradiotherapy Followed by Durvalumab in Participants With Stage III Non-small Cell Lung Cancer (MK-7684A-006/KEYVIBE-006)

Clinical Trial Summary

This study is to evaluate the safety and efficacy of pembrolizumab/vibostolimab (MK-7684A) in combination with concurrent chemoradiotherapy (cCRT) followed by pembrolizumab/vibostolimab versus cCRT followed by durvalumab in participants with unresectable, locally advanced, stage III Non-small Cell Lung Cancer (NSCLC). The primary hypotheses are that pembrolizumab/vibostolimab with cCRT followed by pembrolizumab/vibostolimab is superior to cCRT followed by durvalumab with respect to the following:

• progression free survival (PFS) per Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1 by blinded independent central review (BICR) in participants with programmed cell death ligand 1 (PD-L1) tumor proportion score (TPS) ≥1% and PD-L1 all comer participants.

• overall survival (OS) in participants with PD-L1 TPS ≥1% and PD-L1 all comer participants.

Up to approximately 75 months
Secondary	Number of Participants Who Discontinue Study Treatment Due to an Adverse Event (AE)	An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention.	Up to approximately 75 months
Secondary	Duration of Response (DOR) For All Participants	Duration of Response (DOR) is the time from first documented evidence of Complete Response (CR: disappearance of all target lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) until progressive disease (PD) or death. DOR per RECIST 1.1 will be assessed by blinded independent central review (BICR).	Up to approximately 75 months
Secondary	Duration of Response (DOR) For Participants With Programmed Cell Death Ligand 1 (PD-L1) Tumor Proportion Score (TPS) =1%	Duration of Response (DOR) is the time from first documented evidence of Complete Response (CR: disappearance of all target lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) until progressive disease (PD) or death. DOR per RECIST 1.1 will be assessed by blinded independent central review (BICR).	Up to approximately 75 months

Participant responses to Items 29 and 30 ("How would you rate your overall health during the past week?" and "How would you rate your overall QoL during the past week?") are scored on a 7-point scale (1=Very Poor to 7=Excellent). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. A higher score indicates a better overall health status.	Baseline (at randomization) and at the end of study (approximately 75 months post randomization)
Secondary	Change from Baseline in the Global Health Status/Quality of Life Items 29 and 30 Combined Score on the EORTC QLQ-C30 For Participants With PD-L1 TPS =1%	The EORTC-QLQ-C30 is a 30-item questionnaire developed to assess the quality of life (QoL) of individuals with cancer. Participant responses to Items 29 and 30 ("How would you rate your overall health during the past week?" and "How would you rate your overall QoL during the past week?") are scored on a 7-point scale (1=Very Poor to 7=Excellent).

Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. A higher score indicates more chest pain.	Baseline (at randomization) and at the end of study (approximately 75 months post randomization)
Secondary	Change from Baseline in Dyspnea (Item 8) Score on the EORTC QLQ-C30 For All Participants	The EORTC QLQ-C30 is a cancer specific health-related quality of life (QoL) questionnaire. Participant responses to the question "Were you short of breath?" are scored on a 4-point scale (1=Not at All to 4=Very Much). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. A higher score indicates a worse level of dyspnea.	Baseline (at randomization) and at the end of study (approximately 75 months post randomization)

Secondary	Time to True Deterioration (TTD) in the Global Health Status/Quality of Life Items 29 and 30 Combined Score on the EORTC QLQ-C30 For All Participants	The EORTC-QLQ-C30 is a 30-item questionnaire developed to assess the quality of life (QoL) of individuals with cancer. Participant responses to Items 29 and 30 ("How would you rate your overall health during the past week?" and "How would you rate your overall QoL during the past week?") are scored on a 7-point scale (1=Very Poor to 7=Excellent). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. A higher score indicates a better overall outcome. TTD is defined as the time to first onset of =10-point deterioration (out of 100) from baseline and confirmed by a second adjacent =10-point deterioration from baseline.	Up to approximately 75 months post randomization

Secondary	Time to True Deterioration (TTD) in Physical Functioning (Items 1-5) Combined Score on the EORTC QLQ-C30 For All Participants	The EORTC-QLQ-C30 is a 30-item questionnaire developed to assess the quality of life (QoL) of individuals with cancer. Participant responses to 5 questions about their physical functioning are scored on a 4-point scale (1=Not at All to 4=Very Much). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. A higher score indicates a better level of function. TTD is defined as the time to first onset of =10-point deterioration (out of 100) from baseline and confirmed by a second adjacent =10-point deterioration from baseline.
