Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Disease Control Rate (DCR) | DCR was defined as the percentage of participants who have a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: At least a 30% decrease in the sum of diameters of target lesions) or a Stable Response per RECIST 1.1 | up to approximately 2 year | 
| Progression Free Survival (PFS) include PFS1,PFS2 | PFS was defined as the time from first day of study treatment to the first documented PD or death due to any cause during the specific treatment period, whichever occurred first | up to approximately 2 year | 
| Overall Survival (OS) | OS was defined as the time from first day of study treatment to death due to any cause. Participants without documented death at the time of the final analysis were censored at the date of the last follow-up | up to approximately 3 year | 
| Safety: AE | Safety was defined as the Number of Participants With an Adverse Event | up to approximately 2 year | 
| Change From Baseline in Health-related Quality of life (HRQoL) Score Using European Organization for the Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30) | The EORTC QLQ-C30 is a questionnaire to assess the overall HRQoL. Participant responses to the question  How would you rate your overall quality of life (QoL) during the past week? are scored on a 7-point scale (1=Very Poor to 7=Excellent). A higher score indicates a better overall QoL. Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. The change from baseline in HRQoL EORTC QLQ-C30 score in participants will be presented. | up to approximately 2 year | 
| Change From Baseline in HRQoL Score Using EORTC Quality of Life Questionnaire-Oesophageal Module (QLQ-OES18) | The EORTC QLQ-OES18 is a disease-specific questionnaire to assess measurements specific to esophageal cancer. It contains 18 items and is based on four subscales-dysphagia, eating, reflux and pain. All items are scored using a four-point scale that offers these response choices: 1=not at all, 2=a little, 3=quite a bit, 4=very much. A higher score indicates worse level of symptoms. Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. The change from baseline in HRQoL QLQ-OES18 score in participants will be presented. | up to approximately 2 year | 
| The 1-year OS rate | OS was defined as the time from first day of study treatment to death due to any cause. Participants without documented death at the time of the final analysis were censored at the date of the last follow-up | 1 year | 
| The 2-year OS rate | OS was defined as the time from first day of study treatment to death due to any cause. Participants without documented death at the time of the final analysis were censored at the date of the last follow-up | 2 years | 
| The 3-year OS rate | OS was defined as the time from first day of study treatment to death due to any cause. Participants without documented death at the time of the final analysis were censored at the date of the last follow-up | 3 years |
