Event-Free Survival (EFS)
時間枠:From randomization until the first occurrence of a protocol-defined EFS event, death, withdrawal from study follow-up, or study completion, assessed for up to approximately 36 months.
|
EFS is defined as the time from randomization to the earliest occurrence of a protocol-defined EFS event, including radiographic and/or clinical disease progression that precludes initiation or completion of planned definitive curative-intent therapy; locoregional recurrence, progression, or distant metastasis following definitive treatment, confirmed by imaging, pathology, salvage intervention with viable tumor or other protocol-defined assessments, where applicable, or death from any cause. EFS will be analyzed by blinded independent central review (BICR) using RECIST v1.1 and protocol-defined pathology criteria, as applicable. The primary analysis will be conducted in the intent-to-Treat ( ITT) population using stratified log-rank testing and Cox proportional hazards models. |
From randomization until the first occurrence of a protocol-defined EFS event, death, withdrawal from study follow-up, or study completion, assessed for up to approximately 36 months.

EuroQol-5 Dimension, 5-Level (EQ-5D-5L).
Change from baseline in the EQ-5D-5L Health Utility Index score.
The Health Utility Index is derived from responses to the five EQ-5D-5L dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) using a country-specific value set.
Scores typically range from less than 0 (health states considered worse than death) to 1.0 (full health), with higher scores indicating better health-related quality of life.

Baseline through approximately 36 months.
