OS was defined as the time from randomization to the date of death from any cause. Per the sSAP, the China Cohort was evaluated for efficacy separately from the Global Cohort, with Final Analysis performed using a data cut-off of 27-Sep-2024.

PFS was defined as the time from date of randomization to the date of the first documentation of progressive disease (PD) or death from any cause, whichever occurs first. Per RECIST 1.1 modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ, PD was defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. Note: The appearance of one or more new lesions was also considered PD. PFS as assessed by BICR per modified RECIST 1.1 is presented. Per the sSAP, Final Analysis for the Global Cohort was performed with a data cut-off date of 20-Feb-2023.

An adverse event is defined as 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. Per the sSAP, Final Analysis for the Global Cohort was performed with a data cut-off date of 20-Feb-2023.

The EORTC QLQ-C30 is a cancer specific health-related quality-of life (QoL) questionnaire. Participant responses to the questions regarding Global Health Status (GHS; "How would you rate your overall health during the past week?") and Quality of Life (QoL; "How would you rate your overall quality of life 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. The change from baseline in GHS (EORTC QLQ-C30 Item 29) and QoL (EORTC QLQ-C30 Item 30) combined score is presented. A higher score indicates a better outcome.

The EORTC QLQ-C30 is a cancer specific health-related quality-of life (QoL) questionnaire. Participant responses to 5 questions about their physical functioning (Items 1-5) 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. Higher scores meant a better level of function. The change from baseline in the EORTC QLQ-C30 Physical Functioning (Items 1-5) scale score is presented.

The EORTC QLQ-C30 is a cancer specific health-related quality-of life (QoL) questionnaire, including a single-item scale score for appetite loss (QLQ-C30 Item 13). For this item, individual responses to the question "Have you lacked appetite?" are given on a 4-point scale (1=Not at all; 4=Very much). Scores are transformed to a range from 0-100, with a lower score indicating a better outcome. The change from baseline in the EORTC QLQ-C30 appetite loss (Item 13) scale score is presented.

The EORTC QLQ-CR29 is a health-related quality-of life (QoL) questionnaire specific for colorectal cancer, including a single-item scale score for bloating (QLQ-CR29 Item 37). For this item, individual responses to the question "Did you have a bloated feeling in your abdomen?" are given on a 4-point scale (1=Not at all; 4=Very much). Scores are transformed to a range from 0-100, with a lower score indicating a better outcome. The change from baseline in the EORTC QLQ-CR29 bloating (Item 37) scale score is presented.

TTD is defined as the time from baseline to the first onset of a ≥10-point deterioration (decrease) from baseline in Global Health Status (GHS; EORTC QLQ-C30 Item 29) & Quality of Life (QoL; EORTC QLQ-C30 Item 30) combined score. Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. The TTD, as assessed based on a ≥10-point negative change (decrease) from baseline in GHS and QoL combined score, is presented. A longer TTD indicates a better outcome.

TTD is defined as the time from baseline to the first onset of a ≥10-point deterioration (decrease) from baseline in physical functioning score (QLQ-C30 Items 1-5). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. The TTD, as assessed based on a ≥10-point negative change (decrease) from baseline in physical functioning score, is presented. A longer TTD indicates a better outcome.

TTD is defined as the time from baseline to the first onset of a ≥10-point deterioration (increase) from baseline in appetite loss (QLQ-C30 Item 13) score. Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. The TTD, as assessed based on a ≥10-point change (increase) from baseline in appetite loss score, is presented. A longer TTD indicates a better outcome.

TTD is defined as the time from baseline to the first onset of a ≥10-point deterioration (increase) from baseline in bloating (QLQ-CR29 Item 37) score.
