TroFuse-019: A Study to Assess Efficacy and Safety of Pembrolizumab With or Without Sacituzumab Tirumotecan (MK- 2870) in Adult Participants With Resectable Non Small Cell Lung Cancer (NSCLC) Not Achieving Pathological Complete Response (pCR) (MK-2870-019)

OS is defined as the time from randomization to death due to any cause.

DMFS is defined as the time from randomization to the first documented distant metastasis or death due to any cause, whichever occurs first. Distant metastasis refers to cancer that has spread from the original (primary) tumor to distant organs or distant lymph nodes.

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

LCSS is defined as the time from randomization to the date of death due to lung cancer.

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. The percentage of participants who discontinue study treatment due to an AE will be presented.

The European Organisation for Research and Treatment of Cancer (EORTC) quality of life questionnaire (QLQ) is a psychometrically and clinically validated instrument appropriate for assessing the health-related quality of life (HRQoL) of cancer patients in oncology studies. Each scale or item is scored between 0 and 100, for the global health status or QoL a higher value indicates a better level of function.

The EORTC-QLQ is a psychometrically and clinically validated instrument appropriate for assessing the HRQoL of cancer patients in oncology studies. Each scale or item is scored between 0 and 100, for all physical functional scales, a higher value indicates a better level of function.

The EORTC-QLQ is a psychometrically and clinically validated instrument appropriate for assessing the HRQoL of cancer patients in oncology studies. Each scale or item is scored between 0 and 100, for all role functional scales, a higher value indicates a better level of function.

The EORTC-QLQ is a psychometrically and clinically validated instrument appropriate for assessing the HRQoL of cancer patients in oncology studies. Each scale or item is scored between 0 and 100, for symptom scales such as dyspnea, a higher value indicates increased severity of symptoms.

The lung cancer module of the EORTC, QLQ-LC24 is a revised and updated version of the Lung Cancer Module QLQ-LC13 and is a supplementary lung cancer specific module to be used along with EORTC QLQ C30. The QLQ-LC24 incorporates 4 multi-item scales to assess coughing, shortness of breath, hair problems, and fear of progression, for symptom scales as for cough, a higher value indicates increased severity of symptoms.
