Objective response rate is defined as the percentage of participants who had a best overall response of confirmed complete response (CR) or partial response (PR) assessed by the Investigator according to the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.

Response evaluations were performed using computed tomography or magnetic resonance imaging (MRI) approximately every 6 weeks for the first 54 weeks and then every 12 weeks thereafter.

CR: Disappearance of all target and non-target lesions; any pathological lymph nodes (whether target or non-target) \< 10 mm, and no new lesions.

PR: At least a 30% decrease in the size of target lesions, with no progression of non-target lesions and no new lesions, or disappearance of target lesions with persistence of 1 or more non-target lesion(s) and/or maintenance of tumor marker level above the normal limits, and no new lesions.

Response (CR or PR) must have been confirmed 4 weeks or later after the first response was observed.

Change From Baseline in European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30) Global Health Status (GHS)/Quality of Life (QOL) and Physical Functioning ScoresBaseline, Cycle 5 Day 1 and Cycle 7 Day 1 (each cycle was 3 weeks)

The EORTC QLQ-30 contains 30 questions that incorporate 5 functional scales (physical functioning, role functioning, emotional functioning, cognitive functioning, and social functioning), 1 global health status scale, 3 symptom scales (fatigue, nausea and vomiting, and pain), and 6 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties). The participant answers questions about their health during the past week. There are 28 questions answered on a 4-point scale where 1 = Not at all (best) and 4 = Very Much (worst) and 2 global health quality of life (QOL) questions answered on a 7-point scale where 1 = Very poor and 7 = Excellent. Raw scores are transformed into a 0 to 100 scale via linear transformation. Higher scores in GHS and functional scales indicate better quality of life.

Change From Baseline in EORTC Quality of Life Oesophageal Cancer Questionnaires 18 (QLQ-OES18) Dysphagia, Eating, Reflux and Pain ScalesBaseline, Cycle 5 Day 1 and Cycle 7 Day 1 (each cycle was 3 weeks)

The EORTC-QLQ-OES18 is the specific esophageal symptoms module of the QLQ-C30. QLQ-OES18 is comprised of 18 questions grouped into 4 multi-item subscales: Dysphagia (3 items), Eating (4 items), Reflux (2 items), and Pain (3 items) and 6 single item subscales (saliva swallowing, choking, dry mouth, taste, coughing, and talking). Participants indicate the extent to which they have experienced symptoms on a scale from 1 (Not at all) to 4 (Very much). Scores are calculated and transformed to a scale from 0 to 100; higher scores indicate a higher level of symptomatology or problems.

Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)From first dose of study drug until 30 days after last dose; median duration of treatment was 3.45 months in Tislelizumab + Ociperlimab arm and 2.79 months in the Tislelizumab + Placebo arm.

An AE is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study drugs, whether related to study drugs or not.

An SAE is any untoward medical occurrence that, at any dose:

* Resulted in death

* Was life-threatening

* Required hospitalization or prolongation of existing hospitalization

* Resulted in disability/incapacity

* Was a congenital anomaly/birth defect

* Was considered a significant medical AE by the Investigator based on medical judgement.

AEs were considered "related" to study drugs if there was evidence to suggest a causal relationship.

The investigator assessed the severity of each AE reported based upon National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) v5.0, where ≥ 3 includes severe or medically significant, life-threatening events or death related to AE.

Immune-mediated AEs were diagnosed by the investigator.
